    Full Text Available Se realizó un estudio epidemiológico transversal en 3 áreas de salud del municipio Santa Clara en el período de enero a diciembre de 1999, con el objetivo de determinar la condición periodontal de los encuestados y establecer sus nexos con factores locales y sistémicos existentes. Se determinó la prevalencia y gravedad de la enfermedad periodontal mediante la aplicación del índice de necesidad de tratamiento periodontal en la comunidad, y se relacionaron sus categorizaciones con factores locales y generales explorados durante el estudio. La prevalencia fue alta, vinculada con la edad y con el grado de higiene bucal. El hábito de fumar se asoció con la enfermedad ya establecida, la caries dental con estados incipientes; los casos con maloclusiones eran mayoritariamente enfermos y la patología sistémica más asociada con la enfermedad periodontal fue la diabetes.A cross-sectional epidemiological study was conducted in 3 health areas of the municipality of Santa Clara from January to December, 1999, with the aim of determining the periodontal conditions of the surveyed and to establish its links with the existing local and systemic factors. The prevalence and severity of the periodontal disease was determined by applying the index of need of periodontal treatment in the community and its categorizations were related to local and general factors explored during the study. The prevalence was high related to the age and to the degree of oral hygiene. Smoking was associated with the already established disease, whereas dental caries were associated with incipient states. Most of the cases with malocclusions were sick and diabetes was the systemic pathology most associated with periodontal disease.

    María Elena González Díaz

    Full Text Available De forma compactada se explica la relación biológicamente plausible que existe entre la aparición de accidentes cerebrovasculares, particularmente de infarto cerebral isquémico aterotrombótico y la precedencia de enfermedad periodontal inmuno-inflamatoria crónica. Se sugiere la necesidad de estudios que vinculen ambas entidades para conciliar los resultados de las investigaciones internacionales con las realizadas en nuestro medio. Se propone el análisis del estado periodontal en los pacientes pertenecientes a grupos de riesgo o víctimas de enfermedades cerebrovasculares. La consideración de la enfermedad periodontal inmuno-inflamatoria crónica como un factor de riesgo más para el infarto cerebral isquémico aterotrombótico, debe pasar de una interrogante a una estrategia.

    Full Text Available Se realizó una revisión bibliográfica exhaustiva acerca de la presencia de enfermedad periodontal como factor de riesgo asociado con diversas enfermedades sistémicas. Algunos autores han propuesto el nacimiento de la medicina periodontal, como nueva disciplina, para explicar estas asociaciones. Las evidencias que emergieron en el último decenio arrojaron luz sobre el lado inverso de la relación entre salud general y salud bucal, o sea, los efectos potenciales de la enfermedad periodontal sobre una amplia variedad de sistemas de órganos. En los últimos años han surgido numerosos informes basados en estudios epidemiológicos en los que las infecciones buco-dentales se asocian con enfermedades sistémicas, entre ellas alteraciones cerebrovasculares, respiratorias, diabetes mellitus y resultados adversos del embarazo, debido a los lipopolisacáridos, las bacterias gramnegativas viables del biofilm y citoquinas proinflamatorias que pueden ingresar al torrente sanguíneo e influir en la salud general y susceptibilidad a ciertas enfermedades. Se reúnen los modelos de interacción y mecanismos propuestos, además de evidencias que sustentan las teorías proclamadas, prestando especial interés a la causalidad entre ambos procesos.An exhaustive bibliographic review of the presence of the periodontal disease as a risk factor associated with diverse systemic diseases was made. Some authors have proposed the emergence of periodontal medicine as a new discipline to explain these associations. The evidences that appeared in the last decade shed light on the opposite side of the relation between general health and oral health, that is, the potential effects of the periodontal diseases on a wide range of organ systems. In the last years, several reports have been based on epidemiological studies in which the oro-dental diseases are associated with systemic diseases, such as cerebrovascular and respiratory disorders, diabetes mellitus and adverse

    Full Text Available La enfermedad periodontal inflamatoria ocasiona la destrucción de los tejidos que protegen y soportan al diente; es por eso de gran importancia el papel que pueden desempeñar las enzimas que sean capaces de degradar la matriz del tejido conectivo, como las enzimas proteolíticas. Existen evidencias de que las metaloproteinasas de la matriz, las proteasas leucocitarias y las bacterianas, pueden participar en la etiopatogenia de esta enfermedad. Su acción es regulada en los tejidos, por la presencia de inhibidores específicos, de manera que un desbalance proteasas-inhibidores a favor de los primeros, conduciría a la destrucción de las proteínas de la matriz del tejido conectivo. A su vez, en la actividad proteolítica influyen diferentes factores, que de manera global, inducen un fenotipo degradativo o formativo, y que por lo tanto, podrían estar involucrados en la etiopatogenia de la enfermedad periodontal inflamatoria.The periodontal disease brings about the destruction of the protective and supporting tissues of the teeth, therefore, the role of enzymes capable of degrading connective tissue matrix is of great importance. There are evidences of the possible involvement of the matrix metalloproteinases, leukocyte proteases and bacterial proteases in the pathogenesis of such disease. Their action is controlled by specific inhibitors in the tissues. This means that any protease-inhibitor imbalance favouring the presence of proteases may lead to the destruction of matrix connective tissue. In turn, proteolytic activity is influenced by different factors that globally induce a degradative or formative phenotype, and thus, may be involved in the pathogenesis of the periodontal disease.

    2017-01-01

    Full Text Available La Proteína C Reactiva (PCR es una de las proteínas plasmáticas que aparecen en la fase aguda de la inflamación. La periodontitis se relaciona con niveles elevados de PCR en adul tos y con una reducción de la misma después de su tratamiento. La diabetes, por otro lado, es una enfermedad que compromete la respuesta tanto inflamatoria como reparativa del organismo y los tejidos periodontales son particularmente sensibles a su efecto. La PCR por lo tanto, puede ser útil en el diagnóstico y en la determinación de progresión de la enfermedad periodontal (EP. El objetivo del presente estudio fue evaluar los niveles de PCR en pacientes con EP y pacientes con EP y diabetes mellitus tipo 2 (DM2. Se incluyeron 60 sujetos distribuidos en 3 grupos: 15 pacientes con EP (Grupo 1, 15 pacientes con EP y DM2 (grupo 2 y 30 pacientes sistémicamente sanos (grupo 3. A cada uno de los participantes se les realizaron pruebas bioquímicas: Proteína C Re activa (NycoCard® PCR, HbA1c (NycoCard® y glucosa en sangre. Para el diagnóstico de la enfermedad periodontal se siguieron los parámetros del 5° Taller Europeo de Periodontología. Para evaluar las diferencias entre los grupos se usó la prueba de Kruskal Wallis. Se encontraron diferencias estadísticas significativas al comparar la concentración de PCR en los 3 grupos (p<0.01, siendo el grupo de pacientes sanos el que presentaba el menor promedio (4.88±0.08 y los mayores promedios para los grupos de EP (5 .95±2.23 y EP/DM2 (5.21±0.20. Además se encontraron diferencias significativas (p<0.01 en los tres grupos con respecto a la concentración hemoglobina, talla, IMC y PI. Los resultados indican que los niveles séricos de PCR se elevan en pacientes con EP y en pacientes con EP y DM2. Aunque se notó esta diferencia, existen diversos factores tanto locales como sistémicos que pueden potencialmente influir en los niveles de PCR y estos representan una limitación y dificultad al momento de

    Full Text Available La peroxidación de los lípidos de las membranas de los tejidos periodontales, parece estar implicada en la etiopatogenia de la enfermedad periodontal inflamatoria. En este estudio utilizamos perros Beagles, a los cuales se les provocó la enfermedad, por ligadura de los dientes de una hemiarcada, mientras la hemiarcada opuesta se empleó como control. Al final del experimento, las variables estudiadas (profundidad del surco gingival, altura ósea y niveles de malonil-dialdehído fueron significativamente superiores en la hemiarcada ligada, con respecto a la no ligada. Concluimos que el uso de este modelo es factible en nuestras condiciones. Estos resultados apoyan la teoría de la participación de la peroxidación lipídica en la etiopatogenia de la enfermedad periodontal inflamatoria.The lipid peroxidation of the periodontal membranes seems to be involved in the pathogenesis of the periodontal disease. We used for this study Beagles dogs which were caused such a disease by applying a ligature to a dental hemiarch teeth whereas the opposite hemiarch was used as a control. At the end of the experiment, the studied variables (gingival sulcus depth, bone height and malonyl-dialdehyde levels were significantly higher in the ligated hemiarch. We concluded that the use of this model is feasible in our conditions. These results back up the theory of the role of lipid peroxidation in the pathogenesis of the periodontal diseases.

We found association between the myocardial infarction and cigarette smoking, high blood pressure, cholesterol above 250 mg/dl, triglycerides above 150 mg/dl, uric acid over 8 mg/dill men or 6 mg/dill women, family history of diabetes or coronary heart disease, sedentary Life style, amount of coffee drinking and use of birth-control pills. These factors were synergistic. The high prevalence of smoking In the general population leads to the suggestion that It Is the most Important risk factor and that It could explain the greater number of cases of coronary disease, even If the association was not strong. Any public health actions aimed at reducing the frequency of this disease should include smoking reduction.

    Multivariate statistical analysis is indispensable to assess the associations and interactions between different factors and the risk of periodontitis. Among others, regression analysis is a statistical technique widely used in healthcare to investigate and model the relationship between variables. In our work we study the impact of socio-demographic, medical and behavioral factors on periodontal health. Using regression, linear and logistic models, we can assess the relevance, as risk factors for periodontitis disease, of the following independent variables (IVs): Age, Gender, Diabetic Status, Education, Smoking status and Plaque Index. The multiple linear regression analysis model was built to evaluate the influence of IVs on mean Attachment Loss (AL). Thus, the regression coefficients along with respective p-values will be obtained as well as the respective p-values from the significance tests. The classification of a case (individual) adopted in the logistic model was the extent of the destruction of periodontal tissues defined by an Attachment Loss greater than or equal to 4 mm in 25% (AL≥4mm/≥25%) of sites surveyed. The association measures include the Odds Ratios together with the correspondent 95% confidence intervals.

Leukocyte activation released a great amount of these species the function of which is to eliminate pathogen agents. If antioxidant tissue defenses do not act properly, then radical reactions affecting biomolecules are induced. The attack on cell membrane lipids caused their peroxidation followed by the formation of new radical species and toxic metabolites. The existence of a strong inflammatory infiltrate in periodontal tissues in the course of the periodontal disease suggest the possible involvement of reactive oxygen species in the pathogenesis of this disease. It is supposed that the attack of these substances on the poorly antioxidant defended periodontal tissues makes the lipid peroxidation take place, which may lead to cellular lysis and proteases activation.

    Multiple risk factor syndrome is a clustering of cardiovascular risk factors, such as diabetes, dyslipidemia, hypertension, and obesity associated epidemiologically with insulin resistance. This report describes the clinical course of a patient suffering from severe periodontitis with multiple risk factor syndrome, and discusses the association between periodontal infection and systemic health. The patient had a history of type 2 diabetes, dyslipidemia, and hypertension for over 10 years. At baseline, her hemoglobin A1 c was 8.1%. However, she had no diabetic complications except periodontitis. The IgG antibody titers against Porphyromonas gingivalis FDC 381 and SU63 were elevated above the mean of healthy subjects +2 standard deviations. Intensive periodontal treatment, including periodontal surgery, was performed to reduce periodontal infection and bacteremia. Her systemic and periodontal conditions were evaluated longitudinally for 10 years. Following periodontal treatment, antibody titers against Porphyromonas gingivalis and hemoglobin A1c values were significantly improved. The other clinical data and medication for her systemic condition also remained stable during supportive periodontal therapy. However, she developed myocardial infarction, and showed continuous deterioration of hemoglobin A1 c level and periodontitis. The long-term clustering of risk factors, such as diabetes, dyslipidemia, hypertension, and periodontitis, are associated with the development of myocardial infarction. Treatment of systemic conditions in combination with comprehensive periodontal treatment is important in management of patients with multiple risk factor syndrome.

    Full Text Available Over the last two decades, the amount of evidence corroborating an association between dental plaque bacteria and coronary diseases that develop as a result of atherosclerosis has increased. These findings have brought a new aspect to the etiology of the disease. There are several mechanisms by which dental plaque bacteria may initiate or worsen atherosclerotic processes: activation of innate immunity, bacteremia related to dental treatment, and direct involvement of mediators activated by dental plaque and involvement of cytokines and heat shock proteins from dental plaque bacteria. There are common predisposing factors which influence both periodontitis and atherosclerosis. Both diseases can be initiated in early childhood, although the first symptoms may not appear until adulthood. The formation of lipid stripes has been reported in 10-year-old children and the increased prevalence of obesity in children and adolescents is a risk factor contributing to lipid stripes development. Endothelium damage caused by the formation of lipid stripes in early childhood may lead to bacteria penetrating into blood circulation after oral cavity procedures for children as well as for patients with aggressive and chronic periodontitis.

    Full Text Available La gingivitis del embarazo es una enfermedad inflamatoria producida por bacterias con una alta prevalencia, que va del 35 al 100%, según estudios. La severidad de la gingivitis aumentó gradualmente y alcanzó su peak en el tercer trimestre, seguido por una súbita disminución de la severidad en postparto, el cual se correlacionó con un aumento gradual en el nivel plasmático de progesterona y niveles de estrógenos que alcanzan su peak en el tercer trimestre y que sufren una repentina caída después del postparto. La asociación entre gingivitis y aumento de los esteroides sexuales sistémicos ha sido extensamente reportada y los mecanismos biológicos detrás de este florido estado inflamatorio han sido estudiados por décadas. Este artículo muestra el rol de las hormonas sexuales femeninas en la gravedad de la gingivitis aunque la higiene bucal sea buena constantemente.

    “No debemos olvidar que la Psicología forma parte de la medicina y que en su mayor parte no es más que la fisiología de las porciones más altas del cerebro”. Charcot 1891.

    El hecho, que se olvida con tanta frecuencia en la práctica médica, de que el hombre (sano pero sobre todo cuando está enfermo piensa, siente, interpreta correctamente, pero especialmente teme. teme la muerte, teme la enfermedad, teme la incapacidad, teme el dolor, debe ser tenido siempre presente para así no olvidarse de examinar físicamente al paciente, y también explorar sus características psicológicas, su personalidad y sus problemas para poder apreciar adecuadamente sus síntomas de origen orgánico, psicológico o las modificaciones que los factores psicológicos provocan en las enfermedades orgánicas.

    Se olvida también inexplicablemente que el hombre, tanto o más que cualquier otro miembro del reino animal, está dirigido en todos sus actos voluntarios o involuntarios por su Sistema Nervioso Central; que el hombre es lo que su comportamiento lo lleva a ser y que el comportamiento traduce una determinada forma de funcionar cada cerebro.

    El hombre, por tener un cerebro más desarrollado, ha dominado a las demás especies. En la especie humana antes, ahora y siempre el mejor dotado cerebralmente sobresaldrá, en cualquier sentido, sobre sus semejantes y en esto interviene no sólo la capacidad intelectual sino las habilidades de distinto tipo, la capacidad de trabajo, la tenacidad y sobre todo la capacidad de adaptación o de modificación adecuada del ambiente, que es una de las cualidades de la especie humana que más han influido en su progreso.

    En todo sentido, pero especialmente desde el punto de vista médico influye también sobre todo, el adecuado equilibrio emocional. Vive en general más feliz, más tranquilo y más sano el individuo más equilibrado emocionalmente, enfrente de tantas otras

    Full Text Available OBJECTIVE: The main objective of this study was to investigate the risk factors associated with periodontitis in pregnant women. METHODS: This study was conducted in two stages. In Stage 1, a cross-sectional study was conducted to determine the prevalence of periodontitis among 810 women treated at the maternity ward of a university hospital. In Stage 2, the factors associated with periodontitis were investigated in two groups of pregnant women: 90 with periodontitis and 720 without. A hierarchized approach to the evaluation of the risk factors was used in the analysis, and the independent variables related to periodontitis were grouped into two levels: 1 socio-demographic variables; 2a variables related to nutritional status, smoking, and number of pregnancies; and 2b variables related to oral hygiene. Periodontitis was defined as a probing depth > 4 mm and an attachment loss > 3 mm at the same site in four or more teeth. A logistic regression analysis was also performed. RESULTS: The prevalence of periodontitis in this sample was 11%. The variables that remained in the final multivariate model with the hierarchized approach were schooling, family income, smoking, body mass index, and bacterial plaque. CONCLUSION: The factors identified underscore the social nature of the disease, as periodontitis was associated with socioeconomic, demographic status, and poor oral hygiene.

    There have been an association between systemic diseases and hormonal changes particularly diabetes which has been cited as a risk factor in the progression of periodontitis in pregnant women. The incidence and severity of periodontal diseases are increasing at a higher rate and a common condition in pregnant diabetic women among Bangladeshi population. This cross sectional study included 200 pregnant women who were selected from gynecological department and examined at the dental unit. The clinical parameters used were the Silness and Loe plaque index (PI), gingival scores and periodontal status and any relationship to socio demographic variables (age, occupation, level of education and urban or rural residence) and clinical variables (gestation period, previous pregnancy, type of diabetes and periodontal maintenance) were evaluated. The results showed that these clinical parameters increased concomitantly with an increase in the stage of pregnancy and in women with multiple pregnancies. Increased age, lower level of education, unemployment and patients residing in rural areas were associated with significantly higher gingival scores and periodontal measures. Women with increased age and multiple pregnancies usually have less interest to frequent periodontal maintenance showing a significant statistical relation between an increased age and changes in gingival and periodontal status; however no significant association was found between increased age and plaque index. It is concluded that gingival inflammatory symptoms are aggravated during pregnancy in diabetic women and are related to different clinical and demographic variables.

    Both gingival tissue destruction and regeneration are associated with chronic periodontitis, although the former overwhelms the latter. Studies have shown that transforming growth factor beta 1 (TGF-β1), a growth factor largely involved in tissue regeneration and remodeling, is upregulated in chronic periodontitis. However, the gingival expression of connective tissue growth factor (CTGF or CCN2), a TGF-β1-upregulated gene, in patients with periodontitis remains undetermined. Although both CTGF/CCN2 and TGF-b1 increase the production of extracellular matrix, they have many different biological functions. Therefore, it is important to delineate the impact of periodontitis on gingival CTGF/CCN2 expression. Periodontal tissue specimens were collected from seven individuals without periodontitis (group 1) and from 14 with periodontitis (group 2). The expression of CTGF and TGFβ1 mRNAs were quantified using real-time PCR. Analysis using the nonparametric Mann-Whitney U-test showed that the levels of expression of both CTGF/CCN2 and TGFβ1 mRNAs were significantly increased in individuals with periodontitis compared with individuals without periodontitis. Furthermore, analysis using a nonparametric correlation (Spearman r) test showed a positive correlation between TGFβ1 and CTGF/CCN2 mRNAs. The gingival expression levels of CTGF/CCN2 and TGFβ1 mRNAs in individuals with periodontitis are upregulated and correlated. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Se han determinado una serie de factores de riesgo, tanto clásicos como emergentes, implicados en el desarrollo de esta enfermedad. Recientes investigaciones han demostrado que la inflamación juega un papel clave en el desarrollo de la ateroesclerosis. Las células del sistema inmune se encuentran presentes en todos los estadios de las lesiones arterioescleróticasy sus moléculas efectoras pueden acelerar la progresión de las lesiones y orquestar los mecanismos de inflamación inducidos en los síndromes coronarios agudos. La evidencia crítica implica a mediadores de la inmunidad tanto innata como adquirida en los diferentes estados de la ateroesclerosis. Dentro de loscomponentes inmunes involucrados en el proceso de la ateroesclerosis se encuentran componentes celulares como macrófagos, linfocitos, células dendríticas, mastocitos, células NK; componentes humoralescomo anticuerpos, citocinas proinflamatorias y moduladoras de la respuesta inmune, complemento, proteínas de fase aguda; y otros componentes como moléculas de adhesión y de choque térmico. A partirdel esclarecimiento del papel del sistema inmune en el desarrollo de la arterioesclerosis, han surgido una serie de perspectivas diagnósticas y terapéuticas para la enfermedad cardiovascular.

    To evaluate the efficacy of periodontal treatment for the management of cardiovascular risk factors. Eligible studies in Cochrane Controlled Trials Register/CENTRAL, PubMed, EMBASE, and China Biology Medicine disc (CBMdisc) were searched until October 13, 2011. References of the included studies were hand searched. Two reviewers assessed the risk of bias and extracted the data of the included studies in duplicate. Meta-analysis was conducted with Revman 5.1. Six randomized controlled trials involving 682 participants were included. One case had low risk of bias, another one had moderate risk of bias, and the remaining four had high risk of bias. Meta-analysis showed that periodontal treatment has no significant effect on C-reactive protein, total cholesterol, low-density lipoprotein cholesterol, and triglycerides (P > 0.05). However, the treatment had a significant effect on high-density lipoprotein cholesterol [MD = 0.05, 95% CI (0.00, 0.09), P = 0.04]. Periodontal treatment has good effects on controlling high-density lipoprotein cholesterol although more randomized controlled trials must be conducted to verify its effectiveness.

    Full Text Available Introduction: The periodontal disease represents a malady characterized by an extremely high incidence. The manifestations and evolution of the periodontal diseases vary for each form in part, being influenced by systemic and local risk factors. Scope of the study: To evaluate the periodontal status on a group of patients, versus the syste‐ mic and local factors. Materials and method: The study was performed on a group of 170 patients, whose odonto‐periodontal status was evaluated by strict clinical and paraclinical examinations, on establishing the inflammation indices and the periodontal diagnosis. Results: The main cause of the analysis was gingival ble‐ eding; an increased number of smokers was registered among the patients. Out of the local factors, especially important were edentations and malocclusions. Also, a higher number of aggressive generalized periodontites has been noticed. Discussion: The forms of the periodontal diseases are obviously influenced by the systemic context, while the forms of localized chronic periodontitis associa‐ ted with generalized chronic gingivitis reflect the role pla‐ yed by the local risk factors. Conclusions: Stress and smoking represent significant risk factors in the installation of periodontal pathology, with a really alarming preva‐ lence. The aggressive forms of periodontitis showed a higher frequency than that recorded in literature.

    Periodontitis is a chronic bacterial infection characterized by persistent inflammation, connective tissue breakdown and alveolar bone destruction mediated by pro-inflammatory mediators. Tumor necrosis factor-alpha (TNF-α) is an important pro-inflammatory mediator that produced causes destruction of periodontal tissues. The aim of the study is to estimate the salivary TNF-α in chronic and aggressive periodontitis and control participants and further correlate the levels with clinical parameter such as gingival index (GI), plaque index (PI), probing pocket depth (PPD) and clinical attachment loss. The study population consisted of 75 subjects age ranging from 25 to 55 years attending the outpatient section of Department of Periodontics, Saveetha Dental College and Hospital. The study groups included Groups 1, 2, and 3 with participants with healthy periodontium (n = 25), generalized chronic periodontitis (n = 25) and generalized aggressive periodontitis (n = 25), respectively. Salivary samples from the participants were used to assess the TNF-α levels using enzyme-linked immunosorbent assay. GI and PI were found to be significantly higher in chronic and aggressive periodontitis compared to the controls. The mean TNF-α value in chronic periodontitis patients (12.92 ± 17.21 pg/ml) was significantly higher than in control subjects (2.15 ± 3.60 pg/ml). Whereas, in aggressive periodontitis patients the mean TNF-α (7.23 ± 7.67) were not significantly different from chronic periodontitis or healthy subjects. Among periodontitis participants, aggressive periodontitis subjects exhibited a significant positive correlation between the salivary TNF-α and PPD. Salivary TNF-α levels are significantly higher in chronic periodontitis than in healthy subjects, but there was no significant correlation with the clinical parameters.

    Numerous indicators for disease progression have been described in the last decade. The purpose of this study was to examine, longitudinally, a large battery of clinical, microbiological, and immunological indicators, to try to determine whether the presence of one or a combination of these parameters at baseline, would correlate positively with increased attachment and or bone loss (true prognostic factors). Following initial screening, 79 patients with established periodontitis were monitored longitudinally for one year. Whole mouth clinical measurements, plaque gingival and calculus indices, together with pocket depth and attachment level measurements, were repeated every three months. Full mouth radiographic survey, performed at baseline and 12 months, served to determine changes in crestal bone height using an image enhancement technique. Subgingival plaque samples were taken at baseline and every 3 months. Immunofluorescence assays were performed for the a battery of target microorganisms. Serum and GCF samples for IgG subclasses analysis were obtained at each visit and assayed using ELISA techniques. Likewise blood, samples were also drawn at each visit for a quantitative analysis of serum cotinine level. The overall mean attachment loss (AL) and bone loss (BL) were almost identical (0.159 mm and 0.164 mm, respectively). Individual patients variation was large (-0.733 to +1.004 mm). An overall 6.89% of sites were active; individual patients' means ranged from 0-28.9%. Mean pocket depth (PD) showed minimal change over the study period (-0.033 mm) thus suggesting that most if not all the AL was accompained by concomitant gingival recession. Smokers exhibited greater AL and radiographic BL compared to non-smokers. Likewise, patients' cotinine level showed direct correlation with outcomes of progressive periodontal breakdown. Past severity of periodontal involvement, as reflected in the patients baseline PD, AL and crestal bone height, showed good correlation

    Full Text Available Hepatocyte growth factor (HGF production by oral fibroblasts is enhanced by various molecules that are induced during inflammatory conditions including periodontitis. HGF plays an important role in the progression of periodontitis, by stimulating intense growth of epithelial cells and preventing regeneration of connective tissue attachments. Smokers have a greater risk factor in the pathogenesis and progression of periodontal disease. The objective of the study was to estimate the level of HGF in saliva and gingival crevicular fluid (GCF in smokers with periodontitis and to compare these levels with that of nonsmokers with periodontitis and healthy controls. The HGF levels were found to be significantly high in the saliva and GCF of smokers with periodontitis compared to both never-smokers with periodontitis and the healthy control group. The elevated levels of HGF in the saliva and GCF in the study population could explain the intrinsic mechanism triggering the severity of the periodontitis in smokers. Further studies are necessary to validate the current observations and to establish a sensitive marker to predict periodontal disease activity.

    Full Text Available Objective. To evaluate the effects of psychological stress on periodontitis healing in rats and the contribution of basic fibroblast growth factor (bFGF expression to the healing process. Methods. Ninety-six rats were randomly distributed into control group, periodontitis group, and periodontitis plus stress group. Then, the rats were sacrificed at baseline and week(s 1, 2, and 4. The periodontitis healing condition was assessed, and the expression of interleukin-1β (IL-1β, tumor necrosis factor-α (TNF-α, and bFGF were tested by immunohistochemistry. Results. The stressed rats showed reduced body weight gain, behavioral changes, and increased serum corticosterone and ACTH levels (. The surface of inflammatory infiltrate, alveolar bone loss, attachment loss, and expression of IL-1β and TNF-α in the stress group were higher than those in the periodontitis group at weeks 2 and 4 (. Rats with experimental periodontitis showed decreased bFGF expression (, and the recovery of bFGF expression in the stress group was slower than that in the periodontitis group (. Negative correlations between inflammatory cytokines and bFGF were detected. Conclusion. Psychological stress could delay periodontitis healing in rats, which may be partly mediated by downregulation of the expression of bFGF in the periodontal ligament.

Dentro de éstas, se encuentra la enfermedad renal crónica (ERC, y sus factores de riesgo, diabetes e hipertensión. ERC, cuya prevalencia se estima en 10%, se asocia a un alto riesgo de mortalidad cardiovascular y progresión renal; su evolución es habitualmente silenciosa, y puede pasar inadvertida para los pacientes, médicos y autoridades de salud. Sólo recientemente ha aumentado la conciencia de ERC, como un problema de salud pública, considerando su amplia distribución, complicaciones y costo. Una nueva definición y clasificación de ERC ha contribuido a establecer programas de detección e intervención precoz, que deben hacerse en el nivel de atención primaria. Los gobiernos deben implementar con urgencia programas de tamizaje y vigilancia de ERC, para establecer su magnitud, epidemiología, morbimortalidad y tendencias.

    To determine whether periodontitis is a modifiable risk factor for dementia. Prospective cohort study. National Health Insurance Research Database in Taiwan. Individuals aged 65 and older with periodontitis (n = 3,028) and an age- and sex-matched control group (n = 3,028). Individuals with periodontitis were compared age- and sex-matched controls with for incidence density and hazard ratio (HR) of new-onset dementia. Periodontitis was defined according to International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes 523.3-5 diagnosed by dentists. To ensure diagnostic validity, only those who had concurrently received antibiotic therapies, periodontal treatment other than scaling, or scaling more than twice per year performed by certified dentists were included. Dementia was defined according to ICD-9-CM codes 290.0-290.4, 294.1, 331.0-331.2. After adjustment for confounding factors, the risk of developing dementia was calculated to be higher for participants with periodontitis (HR = 1.16, 95% confidence interval = 1.01-1.32, P = .03) than for those without. Periodontitis is associated with greater risk of developing dementia. Periodontal infection is treatable, so it might be a modifiable risk factor for dementia. Clinicians must devote greater attention to this potential association in an effort to develop new preventive and therapeutic strategies for dementia. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Antimicrobial peptides (AMPs) play a critical role in controlling innate and acquired immune responses. Local dysregulation of AMP is implicated in the pathogenesis of periodontal diseases as a response to periodontal pathogen challenge. Changes in AMP expression also characterize tobacco smoking, diabetes mellitus, obesity and rheumatoid arthritis, which are established risk factors of periodontal diseases, suggesting AMP may act as putative mechanistic links between these. The aim was to evaluate and summarize critically the current evidence pertaining to interrelationships between AMPs, periodontal diseases and selected periodontal disease risk factors. General and theme specific keywords were used to search the PUBMED database for studies relevant to AMP, periodontal diseases, smoking, diabetes mellitus, obesity and rheumatoid arthritis and critically reviewed. A total of 131 abstracts and 119 full text articles were screened for relevance; 13 studies were selected for inclusion after critical review. Local AMP dysregulation characteristic to periodontal diseases appears to occur within a broader landscape of complex systemic immune perturbations independently induced by smoking, metabolic and rheumatoid disease. The nature of these interactions and mechanistic pathways involved are inadequately understood. AMPs could be possible mechanistic interlinks between periodontal diseases and its risk factors. However, such evidence is very limited and more in vivo and in vitro studies are necessary to clarify the nature of such relationships. A greater understanding of AMPs as shared mediators is essential for unraveling their value as therapeutic or biomarker candidates. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Periodontal disease is one of the most common chronic infectious diseases. It has been reported that periodontal disease is associated with various adverse pregnancy outcomes including preterm birth, low birth weight, and gestational diabetes mellitus. Given the fact that the treatment for periodontal disease during pregnancy was ineffective in improving pregnancy outcomes by most of studies, the pre-conception period has been put forward as a more optimal time. However, very few studies have reported the prevalence of periodontal disease among pre-conception women. This study aimed to examine the prevalence and risk factors of periodontal disease among Chinese pre-conception women. A survey was conducted among pre-conception women at the Maternal and Child Health Hospital, Changzhou, China between January 2012 and December 2014. A total of 987 pre-conception women were recruited for a full-mouth dental examination after providing informed consent. A dental examination was carried out by probing six sites per tooth using a manual UNC-15 probe and a recording form. The overall rate of periodontal disease among participants was 73.9% (729/987) (95% confidence interval (CI): 71.0-76.6%). Among women with periodontal disease, 48.0% of cases were mild, 50.9% were moderate and 1.1% were severe. Self-reported bleeding during tooth brushing was the only significant predictive factor for overall periodontal disease (adjusted odds ratio (aOR): 3.71, 95% CI: 2.24, 6.15, P periodontal disease (aOR: 5.17, 95% CI: 3.05, 8.79, P periodontal disease was found in pre-conception Chinese women. Women who have bleeding during tooth brushing could be at increased risk of periodontal disease, and might require further oral health care.

    Periodontal maintenance (PM) is a critical factor in the long-term success of both periodontal and dental implant therapy. Studies have shown both modern periodontal and dental implant therapies are effective in maintaining natural teeth and replacing lost teeth, respectively. However, without a regular program of clinical reevaluation, plaque control, oral hygiene instruction, and reassessment of biomechanical factors, the benefits of treatment often are lost and inflammatory disease in the form of recurrent periodontitis or periimplantitis may result. This article reviews the goals, types, and appropriate frequency of PM in periodontal and dental implant therapy, as well as the incidence and etiology of periimplant disease and strategies for management when recurrent disease develops during the maintenance phase of treatment.

Metabolic elimination of these substance depends on vitamins B6, B12 and folic acid and enzymes such like cistationine -sintase, and metilentetrahidrofolate reductase. The common denominators in heredity deficiency of one fo these enzymes or the ones taking part of the metabolism of the folate or the vitamin B12 are a significant raise of Hcy in blood and cardiovascular diseases. Since these observations, they began to relate the Hcy vith vascular disease. Researches in the last two decades point a moderate raise of Hcy as a risk factor in vascular alterations. This metabolity for mechanisms including activation of some ciagulation factors and inactivation of natural anticoagulants helps the thrombi forming and vascular endothelium damage. The raise of this substance is easy to midify through drug and diet media. Due to this, the Hcy takes part of an analytic parameter of growing use in clinical practice, in cardiovascular diseases patients, in the diagnosis and motitorizing of the response to anemia treatment caused by lack of vitamins B12 and/or folic acid, the value of the risk of having defects of the neural tube or espontaneus abortion, specially in cases where they are repetitive.

    Full Text Available This study was performed to assess the relationship between the amount of green tea that is consumed and periodontitis. It is based on data obtained from the Korea National Health and Nutrition Examination Survey, conducted between 2008 and 2010. A community periodontal index equal to code 3 was defined as moderate periodontitis, and code 4 was defined as severe periodontitis (n = 16,726. Consumption of green tea less than one cup per day was associated with a decreased prevalence of periodontal disease among Korean adults. The association between the consumption of green tea and periodontal disease was independent of various potential confounding factors, such as age, sex, body mass index, smoking, drinking, exercise, metabolic syndrome, frequency of tooth brushing per day, use of secondary oral products, the number of dental examination per year, diabetes, hypertension, and white blood cell count. Adjusted odds ratio and 95% confidence interval of no consumption was 1.360 (1.156, 1.601 when participants with consumption of two times per week ≤ x < 7 times per week was considered as a reference. However, consumption of one or more cups per day increased the prevalence of moderate and severe periodontitis. In conclusion, excessive consumption of green tea may be considered as a risk factor for periodontal disease among Korean adults.

    Full Text Available Actualmente, el control de la enfermedad de Chagas se basa en acciones químicas contra la vinchuca. Sin embargo, existen factores de riesgo como la falta de higiene y el desorden que serían responsables de la persistencia de focos de triatominos. Teniendo en cuenta que las comunidades expuestas al riesgo de contraer la enfermedad poseen escasos conocimientos sobre ella, se definió el nivel óptimo de conocimientos y se determinó el nivel medio de conocimientos de los habitantes de dos zonas epidemiológicamente diferentes de Argentina y se identificaron los factores de riesgo presentes en ambas. El nivel óptimo de conocimientos se definió por 25 "nociones elementales" sobre la enfermedad, a partir de las cuales se elaboraron los cuestionarios para evaluar el nivel medio de conocimientos. Los resultados obtenidos reflejaron un predominio de los factores de riesgo relacionados con la construcción de las viviendas y el desorden y un limitado nivel de conocimientos sobre la enfermedad. Resultó deficiente el conocimiento de información básica sobre la enfermedad, relacionada, por ejemplo, con el reconocimiento de las ninfas y el mecanismo de transmisión. Un mejor conocimiento del tema supondría un importante avance en la lucha contra la enfermedad de Chagas, conduciendo a los habitantes de áreas endémicas a una mejor comprensión de su realidad y a la adquisición de hábitos que les permitan ser los protagonistas de su propio bienestar.

    Khat (Catha edulis) chewing is a highly prevalent habit in the Arabian Peninsula and East Africa, and has recently spread to Western countries. The association between khat chewing and oral mucosal lesions is well documented in the literature. However, there is no concrete evidence on the association between khat chewing and periodontal disease. The purpose of this systematic review was to analyze the influence of khat chewing on periodontal health. A literature search of PubMed, Scopus and Web of Sciences databases was carried out to identify relevant articles published from 1990 to May 2017. The inclusion criteria were all clinical studies that assessed the relationship between khat chewing and periodontal disease. The search yielded 122 articles, of which 10 were included in this systematic review. Most of the studies exhibited a positive correlation between khat chewing and periodontal disease. Altogether, the analysis of the current evidence reveals that khat chewing is destructive to the periodontium and enhances the risk of periodontal disease progression. However, due to variability of studies, more longitudinal case-controlled studies are highly warranted to establish a causal relation between khat chewing and periodontal disease. Key words: Khat chewing, periodontal health, periodontal disease, risk factor.

    Chronic periodontitis is a multifactorial polygenetic disease with an increasing number of associated factors that have been identified over recent decades. Longitudinal epidemiologic studies have demonstrated that the risk factors were related to the progression of the disease. A traditional multivariate regression model was used to find risk factors associated with chronic periodontitis. However, the approach requirement of standard statistical procedures demands individual independence. Multilevel modelling (MLM) data analysis has widely been used in recent years, regarding thorough hierarchical structuring of the data, decomposing the error terms into different levels, and providing a new analytic method and framework for solving this problem. The purpose of our study is to investigate the relationship of clinical periodontal index and the risk factors in chronic periodontitis through MLM analysis and to identify high-risk individuals in the clinical setting. Fifty-four patients with moderate to severe periodontitis were included. They were treated by means of non-surgical periodontal therapy, and then made follow-up visits regularly at 3, 6, and 12 months after therapy. Each patient answered a questionnaire survey and underwent measurement of clinical periodontal parameters. Compared with baseline, probing depth (PD) and clinical attachment loss (CAL) improved significantly after non-surgical periodontal therapy with regular follow-up visits at 3, 6, and 12 months after therapy. The null model and variance component models with no independent variables included were initially obtained to investigate the variance of the PD and CAL reductions across all three levels, and they showed a statistically significant difference (P periodontal therapy with regular follow-up visits had a remarkable curative effect. All three levels had a substantial influence on the reduction of PD and CAL. Site-level had the largest effect on PD and CAL reductions.

La diabetes mellitus (DM se ha convertido en un creciente problema de salud en el mundo. Ahora se sabe que fumar causa diabetes tipo 2 (DM2, también conocida como la diabetes del adulto. Los fumadores tienen entre el 30 y el 40 % más de probabilidades de tener DM2 que los no fumadores. Mientras más cigarrillos fume una persona, más alto es su riesgo de DM. La DM puede producir complicaciones de salud graves como las enfermedades cardiacas, la ceguera, la insuficiencia renal y el daño en los nervios y los vasos sanguíneos de los pies y las piernas, lo cual puede llevar a situaciones como la amputación.

    42 periodontitis patients and 15 health controls are selected to determine the amount of tumor necrosis factor-α (TNF-α) in inflamed gingival and the normal gingival by RIA. The elations between TNF-α and clinical parameters are analysed. The results show that the level of TNF-α in inflamed gingival is higher than that in the controls (P<0.01). The relationship between TNF-α and clinical parameters indicate that the level of TNF-α positively correlate to the degree of periodontitis and group damage. It indicates TNF-α may be one of the mechanism in the pathogenesis of periodontitis disease

    Highlights: Black-Right-Pointing-Pointer Mesenchymal stem cells (MSCs) secrete a variety of cytokines. Black-Right-Pointing-Pointer Cytokines were detected in conditioned medium from cultured MSCs (MSC-CM). Black-Right-Pointing-Pointer MSC-CM enhanced activation of dog MSCs and periodontal ligament cells. Black-Right-Pointing-Pointer MSC-CM significantly promoted alveolar bone and cementum regeneration. Black-Right-Pointing-Pointer Multiple cytokines contained in MSC-CM promote periodontal regeneration. -- Abstract: The effect of conditioned medium from cultured mesenchymal stem cells (MSC-CM) on periodontal regeneration was evaluated. In vitro, MSC-CM stimulated migration and proliferation of dog MSCs (dMSCs) and dog periodontal ligament cells (dPDLCs). Cytokines such as insulin-like growth factor, vascular endothelial growth factor, transforming growth factor-{beta}1, and hepatocyte growth factor were detected in MSC-CM. In vivo, one-wall critical-size, intrabony periodontal defects were surgically created in the mandible of dogs. Dogs with these defects were divided into three groups that received MSC-CM, PBS, or no implants. Absorbable atelo-collagen sponges (TERUPLUG Registered-Sign ) were used as a scaffold material. Based on radiographic and histological observation 4 weeks after transplantation, the defect sites in the MSC-CM group displayed significantly greater alveolar bone and cementum regeneration than the other groups. These findings suggest that MSC-CM enhanced periodontal regeneration due to multiple cytokines contained in MSC-CM.

    Objective Alterations in the microbiome, including the periodontal microbiome, may be a risk factor for rheumatoid arthritis (RA). Most studies that have analyzed this association are relatively small, focus primarily on a single periodontal pathogen (Porphyromonas gingivalis), and are not population-based. We investigated the association between elevated serum IgG antibodies to 19 periodontal species and the prevalence of rheumatoid factor (RF) in a large nationally representative sample of adults. Methods The Third National Health and Nutrition Examination Survey is a cross-sectional sample of the non-institutionalized US population (n=33,994). Our study population included all dentate participants ≥60 years, who did not have RA as defined by a modified version of the American College of Rheumatology 1987 criteria, and had complete data for both serum IgG antibodies against periodontal bacteria and serum RF antibody titer (n=2461). Results Adjusted odds ratios (ORs) (95% CI) summarizing the relationship between the 19 periodontal serum IgGs and RF seropositivity ranged from 0.53 (0.29, 0.97) to 1.27 (0.79, 2.06), and 17 of the 19 observed ORs were periodontal IgGs to be mostly unassociated with RF seropositivity in the nationally representative NHANES III. Elevated antibody levels to P. intermedia and C. ochracea were associated with lower odds of RF seropositivity. PMID:27110949

    Periodontal diseases are associated with bacterial challenge and the host immune response, and are also modulated by genetic factors. There is evidence that sickle cell anaemia (SCA) does not represent a risk factor for periodontal diseases. However, it is still unclear whether the heterozygous condition [sickle cell trait (SCT)] is associated with periodontal diseases. SCT is a genetic condition that can cause vaso-occlusive events, which may be associated with a propensity to bacterial infections. The aim of this study was to investigate the association of SCA and SCT with periodontal diseases by evaluating clinical and radiographic characteristics. The sample (n = 369) was selected and divided into two groups: exposed groups [HbSS (SCA genotype) and HbAS (SCT genotype) = 246] and a nonexposed group (HbAA = 123). HbAA consisted of individuals without SCA and SCT. The clinical parameters evaluated were plaque index, gingival index, calculus index, clinical probing depth, clinical attachment level, gingival recession, tooth mobility and furcation involvement. The percentage of alveolar bone loss was measured using a Schei ruler. Binomial and Poisson regressions were used to estimate correlations of interest (α = 0.05). None of the periodontal parameters was associated with SCA. SCT was associated with gingivitis (p = 0.041) and periodontitis (p = 0.002). Individuals with SCT had a lower plaque index (p = 0.044) but a higher calculus index (p = 0.003) and greater alveolar bone loss (p = 0.010) compared with subjects in the HbAA group. SCT can act as a predictor for establishment of periodontal diseases. There was no correlation between SCA and periodontal diseases. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Iatrogenic factors refer to anyinadequate medical treatment or diagnostic proceduresconducted inadvertently by practitioners who precipitate adverse injuries or symptoms. The unavoidable consequences of these factors should be corrected promptly, as they may result in erroneous treatment or new injury either on the tooth or the periodontium or both. Periodontal disease has a multifactorial etiology, which results from the interaction of local and systemic factors, intrinsically or extrinsically. Therefore, in most cases of periodontal disease, aninterdisciplinary approach is needed, such as restorative treatment of interproximal cavities that may induced food impacted. In contrary, a periodontal therapy could also act as an iatrogenic factor in the case of dentinal hypersensitivity or gingival recessionthat frequently creates an adverse effect in esthetic. Our discussion here is presented so that dentists could treat carefully and give a lot of attention to potential danger of other consequences of iatrogenic factors.

  8. Periodontal disease as a potential factor of migraine chronification.

    Ameijeira, Pablo; Leira, Yago; Blanco, Juan; Leira, Rogelio

    2017-05-01

    Migraine is a hereditary constitutional base disorder, which is characterized by recurrent episodes of headache pulsatile characteristics associated with photophobia/phonophobia, nausea and/or vomiting. The main complication in migraine is the chronicity of the process, now recognized as a chronic migraine. Although pathogenic mechanisms that may influence the pathophysiology of migraine and its possible chronicity are not fully understood, previous studies have shown in patients with migraine molecular alterations of systemic inflammation, neurogenic inflammation, endothelial dysfunction, innate immunity, dysfunction of matrix proteases and blood-brain barrier. Periodontal disease is an inflammatory lesion caused by bacteria. After the bacterial infection begins, an immune response that will be responsible for individual susceptibility appears. More advanced forms of periodontitis have demonstrated molecular alterations of inflammation, endothelial dysfunction, dysfunction of matrix proteases and innate immunity, similar to those observed in migraine. Furthermore, the main molecular mediators of neurogenic inflammation related to activation of the trigeminovascular system, which are characteristic of migraine, are overexpressed in gingival crevicular fluid and mucosa in patients with periodontal disease. Hypertension, hypercholesterolemia, insulin resistance, stroke or coronary artery disease are comorbidities that periodontal disease and migraine could share. Therefore, several mechanisms and hypotheses could explain the possible association between both diseases. However, epidemiological and molecular studies will be necessary to provide a better understanding of this potential association, which could be implicated in the chronification of migraine.

    2014-02-01

    Chronic inflammation is a prominent feature of aging and of common age-related diseases, including atherosclerosis, cancer and periodontitis. This volume examines modifiable risk factors for periodontitis and other chronic inflammatory diseases. Oral bacterial communities and viral infections, particularly with cytomegalovirus and other herpesviruses, elicit distinct immune responses and are central in the initiation of periodontal diseases. Risk of disease is dynamic and changes in response to complex interactions of genetic, environmental and stochastic factors over the lifespan. Many modifiable risk factors, such as smoking and excess caloric intake, contribute to increases in systemic markers of inflammation and can modify gene regulation through a variety of biologic mechanisms (e.g. epigenetic modifications). Periodontitis and other common chronic inflammatory diseases share multiple modifiable risk factors, such as tobacco smoking, psychological stress and depression, alcohol consumption, obesity, diabetes, metabolic syndrome and osteoporosis. Interventions that target modifiable risk factors have the potential to improve risk profiles for periodontitis as well as for other common chronic diseases. © 2013 John Wiley & Sons A/S.

    Bacterial invasion in subgingival sites especially of gram-negative organisms are initiators for periodontal diseases. The periodontal pathogens with persistent inflammation lead to destruction of periodontium. In recent years, periodontal diseases have been associated with a number of systemic diseases such as rheumatoid arthritis, cardiovascular-disease, diabetes mellitus, chronic respiratory diseases and adverse pregnancy outcomes including pre-term low-birth weight (PLBW) and pre-eclampsia. The factors like low socio-economic status, mother's age, race, multiple births, tobacco and drug-abuse may be found to increase risk of adverse pregnancy outcome. However, the same are less correlated with PLBW cases. Even the invasion of both aerobic and anerobic may lead to inflammation of gastrointestinal tract and vagina hence contributing to PLBW. The biological mechanism involved between PLBW and Maternal periodontitis is the translocation of chemical mediators of inflammation. Pre-eclampsia is one of the commonest cause of both maternal and fetal morbidity as it is characterized by hypertension and hyperprotenuria. Improving periodontal health before or during pregnancy may prevent or reduce the occurrences of these adverse pregnancy outcomes and, therefore, reduce the maternal and perinatal morbidity and mortality. Hence, this article is an attempt to review the relationship between periodontal condition and altered pregnancy outcome.

    The treatment of oral and periodontal diseases and associated anomalies accounts for a significant proportion of the healthcare burden, with the manifestations of these conditions being functionally and psychologically debilitating. A challenge faced by periodontal therapy is the predictable regeneration of periodontal tissues lost as a consequence of disease. Growth factors are critical to the development, maturation, maintenance and repair of oral tissues as they establish an extra-cellular environment that is conducive to cell and tissue growth. Tissue engineering principles aim to exploit these properties in the development of biomimetic materials that can provide an appropriate microenvironment for tissue development. The aim of this paper is to review emerging periodontal therapies in the areas of materials science, growth factor biology and cell/gene therapy. Various such materials have been formulated into devices that can be used as vehicles for delivery of cells, growth factors and DNA. Different mechanisms of drug delivery are addressed in the context of novel approaches to reconstruct and engineer oral and tooth supporting structure. Key words: Periodontal disease, gene therapy, regeneration, tissue repair, growth factors, tissue engineering. PMID:22143705

    The acute phase of chronic periodontitis may occur even in patients during supportive periodontal therapy. However, the details are not fully understood. Since the natural environment, including meteorology affects human health, we hypothesized that weather conditions may affect occurrence of acute phase of chronic periodontitis. The aim of this study was to investigate the relationship between weather conditions and acute phase of chronic periodontitis in patients under supportive periodontal therapy. Patients who were diagnosed with acute phase of chronic periodontitis under supportive periodontal therapy during 2011-2013 were selected for this study. We performed oral examinations and collected questionnaires and meteorological data. Of 369 patients who experienced acute phase of chronic periodontitis, 153 had acute phase of chronic periodontitis without direct-triggered episodes. When using the autoregressive integrated moving average model of time-series analysis, the independent covariant of maximum hourly range of barometric pressure, maximum hourly range of temperature, and maximum daily wind speed were significantly associated with occurrence of acute phase of chronic periodontitis (p chronic periodontitis.

    Full Text Available BACKGROUND: Periodontal disease is common among adults and is associated with an increasing risk of chronic kidney disease (CKD. We aimed to investigate the prevalence and risk factors of CKD in patients with periodontal disease in China. METHODS: In the current cross-sectional study, patients with periodontal disease were included from Guangdong Provincial Stomatological Hospital between March 2011 and August 2011. CKD was defined as estimated glomerular filtration rate (eGFR <60 mL/min/1.73 m(2, the presence of albuminuria, or hematuria. All patients with periodontal disease underwent a periodontal examination, including periodontal probing pocket depth, gingival recession, and clinical attachment level by Florida Probe. They completed a questionnaire and had blood and urine samples taken. The adjusted prevalence of indicators of kidney damage was calculated and risk factors associated with CKD were analyzed. RESULTS: A total of 1392 patients with periodontal disease were invited to participate this study and 1268 completed the survey and examination. After adjusting for age and sex, the prevalence of reduced eGFR, albuminuria, and hematuria was 2.7% (95% CI 1.7-3.7, 6.7% (95% CI 5.5-8.1 and 10.9% (95% CI 9.2-12.5, respectively. The adjusted prevalence of CKD was 18.2% (95% CI 16.2-20.3. Age, male, diabetes, hypertension, history of CKD, hyperuricemia, and interleukin-6 levels (≥7.54 ng/L were independent risk factors for reduced eGFR.

    Objective: To investigate the periodontal status and associated risk factors among women of childbearing age to increase the awareness of oral health. Methods: The study was conducted on childbearing age women in Cixi, a city in Zhejiang Province in the southeast of China. A total of 754 women participated in periodontal examination while receiving prenatal care. Data of the women were collected from the Cixi Family Planning Commission and during an interview. Clinical periodontal indices, such as bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) were measured during the examination. Statistical analysis on subject-based data was performed. Results: The prevalence of periodontal disease among childbearing age women in Cixi was high (84.7%). A significant association was found between the disease and educational level, pregnancy, taking oral contraceptives, stress, alcohol consumption, overweight, dental visit, and teeth brushing (Pperiodontal disease showed deep PD, obvious BOP, and clinical attachment loss. Among this population, pregnancy was closely associated with higher BOP percentage; teeth brushing no more than once per day or brushing for less than 1 min (Pperiodontal status of childbearing age women in Cixi needs to be improved urgently.

    This study evaluated second-, third-, and fourth-year dental students' ability to identify systemic conditions associated with periodontal disease, risk factors most important for referral, and medications with an effect on the periodontium and their ability to apply this knowledge to make clinical decisions regarding treatment and referral of periodontal patients. A twenty-one question survey was administered at one U.S. dental school in the spring semester of 2012 to elicit the students' knowledge and confidence regarding clinical reasoning. The response rate was 86 percent. Periodontal risk factors were accurately selected by at least 50 percent of students in all three classes; these were poorly controlled diabetes, ≥6 mm pockets posteriorly, and lack of response to previous non-surgical therapy. Confidence in knowledge, knowledge of risk factors, and knowledge of medications with an effect on the periodontium improved with training and were predictive of better referral decision making. The greatest impact of training was seen on the students' ability to make correct decisions about referral and treatment for seven clinical scenarios. Although the study found a large increase in the students' abilities from the second through fourth years, the mean of 4.6 (out of 7) for the fourth-year students shows that, on average, those students missed correct treatment or referral on more than two of seven clinical cases. These results suggest that dental curricula should emphasize more critical decision making with respect to referral and treatment criteria in managing the periodontal patient.

Asimismo, estudiar las ar - ticulaciones entre la biomedicina y el sistema de salud tradicional. Materiales y métodos: Investigación cualitativa, mediante un abordaje etnográfico en el que la observación participante, la corresidencia y las entrevistas abiertas de sesiones múltiples cumplen un rol primordial. La pesquisa se ha centrado en los pobladores locales que regularmente asisten a la posta sanitaria, los enfermeros, los agentes sanitarios y los miembros del equipo de salud itinerante. La población total del lugar es aproximadamente 235 habitantes. Resultados: Se ha constatado que los procesos de salud y enfermedad no se limitan al cuerpo humano, sino que también en ellos intervienen el paisaje y los seres que lo pueblan. Se ha identificado que en la resolución de numerosas patologías resulta central la figura del especialista ritual. Se ha determinado que la gente valora y utiliza la biomedicina, aunque la asistencia a la institución hospitalaria suele ser rehuida. Conclusiones: Se ha identificado un uso combinado de ambos sistemas. En él influyen las valoraciones de las personas sobre la enfermedad de que se trate, pero también otros factores como la distancia hasta el centro asistencial y las relaciones interpersonales con los profe - sionales de la salud. Se resalta la relevancia del enfoque cualitativo para dar cuenta de las especificidades de las categorías locales, que resultan esquivas para un abordaje construido a partir de conceptos derivados del dualismo cartesiano.

This group of respondents has been chosen by presence of such social stressor as change of place of living (97,9% cadets have arrived in St.-Petersburg from other cities and republics of the Russian Federation and strict disciplinary conditions. The research has revealed a low level of oral hygiene, cases of mild gingivitis in most respondents. The general mental state of group under study is characterized by raised level of personal anxiety and low indices of reactive anxiety. The examined group has demonstrated anxiety, tension, indecision and lowered stress stability. Clinically healthy persons are more liable to develop inflammatory and inflammatory-destructive periodontal diseases. It was possible to determine psychophysiological features correlated with physiological parameters of risk degree of periodontal diseases. It may have a great significance in defining of periodontal disease etiology and pathogenesis

    It is inconclusive that periodontitis is an independent risk factor for adverse pregnancy outcomes. This study aims to investigate the association between maternal periodontitis and preterm and/or low birth weight babies. This was a prospective cross-sectional study. After prior informed consent, 3500 postpartum mothers were selected from various hospitals in Tamil Nadu and categorized into the following groups: group-1 - Normal term normal birth weight ( n = 1100); Group-2 - Preterm normal birth weight ( n = 400); Group-3 - preterm low birth weight (PTLBW) ( n = 1000); and Group-4 - Normal term low birth weight ( n = 1000). Periodontal examination was done, and risk factors were ascertained by means of questionnaire and medical records. Comparison between case groups and control groups were done, odds ratio (OR) was calculated, and statistical significance were assessed by Chi-square tests. To control for the possible confounders, all variables with P < 0.05 were selected and entered into multivariate regression model, and OR and 95% confidence limits were again estimated. SPSS-15 software was used. Periodontitis was diagnosed in 54.8%, 52.3%, 53.8%, 59.4%, respectively. On comparison between the groups, none of periodontal parameters showed significant association except for the crude association observed in Group-4 for mild periodontitis (OR - 1.561; P = 0.000) and PTLBW. Periodontitis is not a significant independent risk factor, and obstetric factors contribute a major risk for preterm and/or low birth weight babies.

    Obesity in young adults and adolescents is associated with chronic co-morbidities. This project investigated whether being overweight or obese is a risk factor for periodontitis in adolescents (13-17 years) and young adults (18-34 years). A search of 12 databases was conducted using Medical Subject Headings/Index and Emtree terms. Based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, articles published between 2003 and 2016 were screened that reported periodontal and anthropometric measures. The Newcastle-Ottawa Scale was used to appraise the quality of studies. Of 25 eligible studies from 12 countries, 17 showed an association between obesity and periodontitis (odds ratios ranged from 1.1 to 4.5). The obesity indicators of body mass index, waist circumference, waist-hip ratio and body fat percentage were significantly associated with measures of periodontitis of bleeding on probing, plaque index, probing depths, clinical attachment loss, calculus, oral hygiene index and community periodontal index. Two prospective cohort studies in the review showed no significant association between obesity and periodontitis, but these studies had limitations of study design and used inappropriate epidemiological diagnostic measures of periodontitis. There was evidence to suggest that obesity is associated with periodontitis in adolescents and young adults.

    Stem and progenitor cells are currently being investigated for their applicability in cell-based therapy for periodontal tissue regeneration. We recently demonstrated that the transplantation of adipose tissue-derived multi-lineage progenitor cells (ADMPCs) enhances periodontal tissue regeneration in beagle dogs. However, the molecular mechanisms by which transplanted ADMPCs induce periodontal tissue regeneration remain to be elucidated. In this study, trophic factors released by ADMPCs were examined for their paracrine effects on human periodontal ligament cell (HPDL) function. ADMPC conditioned medium (ADMPC-CM) up-regulated osteoblastic gene expression, alkaline phosphatase activity and calcified nodule formation in HPDLs, but did not significantly affect their proliferative response. ADMPCs secreted a number of growth factors, including insulin-like growth factor binding protein 6 (IGFBP6), hepatocyte growth factor and vascular endothelial growth factor. Among these, IGFBP6 was most highly expressed. Interestingly, the positive effects of ADMPC-CM on HPDL differentiation were significantly suppressed by transfecting ADMPCs with IGFBP6 siRNA. Our results suggest that ADMPCs transplanted into a defect in periodontal tissue release trophic factors that can stimulate the differentiation of HPDLs to mineralized tissue-forming cells, such as osteoblasts and cementoblasts. IGFBP6 may play crucial roles in ADMPC-induced periodontal regeneration. - Highlights: • ADMPC-derived humoral factors stimulate cytodifferentiation of HPDLs. • ADMPCs secret growth factors including IGFBP6, VEGF and HGF. • IGFBP6 is involved in the promotion effect of ADMPC-CM on HPDL cytodifferentiation.

    2017-01-01

    COPD is recognized as having a series of comorbidities potentially related to common inflammatory processes. Periodontitis is one of the most common human inflammatory diseases and has previously been associated with COPD in numerous observational studies. As periodontitis and COPD are both chronic, progressive conditions characterized by neutrophilic inflammation with subsequent proteolytic destruction of connective tissue, it has been proposed that they share common pathophysiological processes. The mechanisms proposed to link COPD and periodontitis include mechanical aspiration of oral contents into the respiratory tree, overspill of locally produced inflammatory mediators into the systemic circulation or oral or lung-derived bacteremia activating an acute-phase response and also reactive oxygen species (ROS) and cytokine release by systemic neutrophils at distant sites. Studies of systemic neutrophils in COPD and chronic periodontitis describe altered cellular functions that would predispose to inflammation and tissue destruction both in the lung and in the mouth, again potentially connecting these conditions. However, COPD and periodontitis also share risk factors such as age, chronic tobacco smoke exposure, and social deprivation that are not always considered in observational and interventional studies. Furthermore, studies reporting associations have often utilized differing definitions of both COPD and periodontitis. This article reviews the current available evidence supporting the hypothesis that COPD and inflammatory periodontal disease (periodontitis) could be pathologically associated, including a review of shared inflammatory mechanisms. It highlights the potential limitations of previous studies, in particular, the lack of uniformly applied case definitions for both COPD and periodontitis and poor recognition of shared risk factors. Understanding associations between these conditions may inform why patients with COPD suffer such a burden of comorbid

    To detect the salivary factors related to caries and periodontal disease and to analyze the risk of caries and periodontal disease in children and adolescents with diabetes mellitus. The study comprised 30 children with diabetic mellitus, aged 7-15 years old, and 60 healthy age-and gender-matched children. Caries and periodontal indexes were recorded and saliva related factors were analyzed. Caries indexes of diabetes children [permanent teeth: decay missing filling tooth (DMFT) M (Q1,Q3) = 0(0, 4), deciduous teeth: decay missing filling tooth (dmft) M (Q1,Q3) = 0(0, 1)] were not significantly different with those of healthy children [DMFT M (Q1,Q3) = 1(0, 3), dmft M (Q1,Q3) = 0(0, 4)], but plaque index (PLI) (1.25 ± 0.33) and bleeding index (BI) (0.74 ± 0.45) of diabetes children were significantly higher than those of healthy children (PLI was 0.93 ± 0.31,BI was 0.34 ± 0.22) (P 0.05). Salivary glucose, immunoglobulin sIgA and sIgG were not significantly different between the two groups (P > 0.05).Salivary lysozyme of diabetes children was significantly higher than that of healthy children (P 0.05). Diabetes mellitus can lead to the changes of some salivary factors related to gingivitis in diabetes children. Children and adolescents with diabetes mellitus may have a higher risk of periodontal disease.

    Full Text Available Dental implant success requires placement after periodontal therapy, with adequate bone volume, plaque control, primary stability, control of risk factors, and use of well-designed prostheses. This report describes the surgical and prosthetic management of a patient with severe iatrogenic periodontal/periimplant bone destruction. Methods. A 55-year-old female smoker with fixed partial dentures (FPDs supported on teeth and implants presented with oral pain, swelling, bleeding, and a 10-year history of multiple implant placements and implants/prosthesis failures/replacements. Radiographs showed severe bone loss, subgingival caries, and periapical lesions. All implants and teeth were removed except implants #4 and #10 which served to retain an interim maxillary restoration. Bone defects were covered with nonresorbable dPTFE membranes. In the mandible, three new implants were placed and loaded immediately with a bar-retained temporary denture. Results. Seven months postoperatively, the bone defects were regenerated, and three additional mandibular implants were placed. All mandibular implants were splinted and loaded with a removable overdenture. Conclusions. In this case, periimplant infection and tissue destruction resulted from the lack of periodontal treatment/maintenance and failure to use evidence-based surgical and loading protocols. Combination therapy resolved the disease and the patient's severe discomfort while providing immediate function and an aesthetic solution.

    Alterations in the microbiome, including the periodontal microbiome, may be a risk factor for rheumatoid arthritis (RA). Most studies that have analyzed this association are relatively small, focus primarily on a single periodontal pathogen (Porphyromonas gingivalis), and are not population based. This study was undertaken to investigate the association between elevated serum levels of IgG antibodies to 19 periodontal species and the prevalence of rheumatoid factor (RF) in a large nationally representative sample of adults. The Third National Health and Nutrition Examination Survey (NHANES-III) is a cross-sectional sample of the noninstitutionalized US population (n = 33,994). Our study population included all dentate participants who were 60 years and older, did not have RA as defined by a modified version of the American College of Rheumatology 1987 criteria, and had complete data for both serum IgG antibodies against periodontal bacteria and serum RF antibody titer (n = 2,461). Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) summarizing the relationship between the 19 periodontal serum IgG antibodies and RF seropositivity ranged from 0.53 (95% CI 0.29-0.97) to 1.27 (95% CI 0.79-2.06), and 17 of the 19 observed ORs were periodontal bacteria are mostly unassociated with RF seropositivity in the nationally representative NHANES-III. Elevated levels of antibodies to P intermedia and C ochracea are associated with lower odds of RF seropositivity. © 2016, American College of Rheumatology.

    Growth/differentiation factor-5 (GDF-5) plays critical roles in mesenchymal cell differentiation and stimulates human periodontal ligament cell proliferation. Potentially, GDF-5 may also play roles in wound healing including periodontal regeneration and alveolar augmentation. The objective of this review was to provide up-to-date information from pre-clinical/clinical studies evaluating GDF-5 for these indications. A comprehensive search using PubMed and Google search engines was conducted to identify reports on GDF-5 applied to periodontal and alveolar indications. Two reviewers independently screened the titles and abstracts from a total of 479 reports. Full-length articles of 17 pre-clinical and four clinical studies were selected and reviewed. Canine-, porcine- and non-human primate-based models as well as human clinical trials were used in the evaluation of GDF-5 in support of periodontal regeneration and alveolar augmentation. An absorbable collagen sponge (ACS), β-tricalcium phosphate (β-TCP) and a poly(lactic-co-glycolic) acid (PLGA) were evaluated as candidate carriers for GDF-5 using various dose and healing intervals demonstrating significantly enhanced periodontal regeneration/alveolar augmentation including cementum, periodontal ligament and alveolar bone with limited, if any, adverse effects. Growth/differentiation factor-5 supports periodontal regeneration/alveolar augmentation without aberrant healing events documented in qualified pre-clinical models and clinical pilot studies. In perspective, GDF-5 appears a promising technology for periodontal regeneration/alveolar augmentation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available To estimate the prevalence and related aspects of periodontitis in a rural area of the State of Bahia, Brazil, this cross-sectional study was carried out in the village of Matinha dos Pretos, Feira de Santana County, Bahia, among 172 subjects ranging from 20 to 60 years of age. During household visits, a full-mouth periodontal exam was performed on each subject, who also answered a questionnaire about socio-demographic, economic and health-related issues. The factors assessed were plaque index, bleeding on probing index, probing depth, gingival recession or hyperplasia measurements. Clinical attachment loss was also calculated. The multivariate logistic regression method was used to evaluate the relative contribution of these factors to the periodontitis condition. The prevalence of periodontitis was 24.4%. The following factors were all positively associated with the presence of periodontitis: being male (OR = 1.58; 1.00 - 2.53, being 30 years of age or older (OR = 2.80; 1.00 - 7.39, living in a house where there was more than one person per room (OR = 1.53; 0.96 - 2.45, being a cigarette or pipe smoker or ex-smoker (OR = 1.49; 0.92 - 2.39, having a plaque index of over 65% (OR = 2.97; 2.72 - 7.39 and more than four missing teeth (OR = 1.51; 0.82 - 2.78.

    Full Text Available Background and Aim: It is inconclusive that periodontitis is an independent risk factor for adverse pregnancy outcomes. This study aims to investigate the association between maternal periodontitis and preterm and/or low birth weight babies. Settings and Design: This was a prospective cross-sectional study. After prior informed consent, 3500 postpartum mothers were selected from various hospitals in Tamil Nadu and categorized into the following groups: group-1 – Normal term normal birth weight (n = 1100; Group-2 – Preterm normal birth weight (n = 400; Group-3 – preterm low birth weight (PTLBW (n = 1000; and Group-4 – Normal term low birth weight (n = 1000. Periodontal examination was done, and risk factors were ascertained by means of questionnaire and medical records. Statistical Analysis: Comparison between case groups and control groups were done, odds ratio (OR was calculated, and statistical significance were assessed by Chi-square tests. To control for the possible confounders, all variables with P < 0.05 were selected and entered into multivariate regression model, and OR and 95% confidence limits were again estimated. SPSS-15 software was used. Results: Periodontitis was diagnosed in 54.8%, 52.3%, 53.8%, 59.4%, respectively. On comparison between the groups, none of periodontal parameters showed significant association except for the crude association observed in Group-4 for mild periodontitis (OR - 1.561; P = 0.000 and PTLBW. Conclusion: Periodontitis is not a significant independent risk factor, and obstetric factors contribute a major risk for preterm and/or low birth weight babies

    Periodontitis and gingivitis are one of the most infectious diseases in human. Several studies have been carried out on dependence of periodontitis and stroke. The aim of this study was to investigate the gingivitis and periodontitis as a risk factor for stroke in Iranian population. A case-control study was conducted on 100 patients suffering from stroke as case group, and 100 hospitalized patients as control group. The case group included 42 males and 58 females, and in control group there were 44 males and 56 females. Using a University of North Carolina-15 manual probe, the clinical attachment level, the distance between the cemento-enamel junction and the probed base of the periodontal pocket, were recorded by gingival and periodontal indexes. The data were analyzed by multiple logistic regressions, Chi-square test, Fisher's test, t-test, Man Whitney, and SPSS11.5 software program. P > 0.05 was considered as significant. The case group included 42 males and 58 females, and in control group 44 males and 56 females were included. In this investigation, the average of gingival index in men and women of case group was 1.22 ± 0.55 and 1.31 ± 0.55, respectively. This study showed that the average of gingival index in case group was more than control group. Periodontal index in both groups in men was more than women. The moderate and severe periodontitis in case group were more than that of control group (P = 0.003, P = 0.001). The result of this study shows that there is a significant relation between stroke and periodontal index; however, there isn't any significant relation between stroke and gingival index.

  11. A critique on nuclear factor-kappa B and signal transducer and activator of transcription 3: The key transcription factors in periodontal pathogenesis

    Full Text Available Periodontal disease is initiated by microorganisms in dental plaque, and host immunoinflammatory response to the microbial challenge helps in disease progression. Conventional periodontal therapy was mainly targeted on the elimination of microbial component. However, a better understanding of molecular aspects in host response will enable the clinicians to formulate effective host modulation therapy (HMT for the periodontal management. Inflammatory mediators were the main targets for HMT in the past. Transcription factors can regulate the production of multiple mediators simultaneously, and inhibition of these factors will be more beneficial than blocking individual molecule. Two important transcription factors implicated in chronic inflammatory diseases are nuclear factor kappa B (NF-κB and signal transducers and activators of transcription 3. The role of these factors in periodontal disease is a less explored area. This comprehensive review is aimed at unveiling the critical role of NF-κB and signal transducers and activators of transcription 3 in periodontal pathogenesis. An online search was performed using MEDLINE/PubMed database. All publications till 2016 related to NF-κB, signal transducer and activator of transcription 3 (STAT3, and inflammation were included in writing this review. A total of 27,390 references were published based on the search terms used. Out of these, 507 were related to the periodontal research published in English till 2016. Relevant papers were chosen after carefully reading the abstract. This review has attempted to comprehend the existing knowledge regarding the role of transcription factors NF-κB and STAT3 in periodontal disease. Moreover, it also provides a connecting molecular link for the periodontal medicine concept.

    Many studies have shown that periodontal diseases are risk factors for adverse pregnancy outcomes. The aim of this study is to assess the knowledge and clinical attitude of French obstetricians and/or gynecologists regarding periodontal diseases. A cross-sectional study was performed on randomly selected French obstetricians and/or gynecologists using a self-administered, structured questionnaire during an annual French professional congress. The questionnaire was completed by 190 French obstetricians and/or gynecologists. Among respondents, 88% were aware of the inflammatory and infectious nature of periodontal diseases. Furthermore, 74.7% of respondents were conscious of its negative impact on pregnancy outcomes. Few obstetricians and/or gynecologists (26.3%) interviewed patients about oral health. Information on oral health was systematically provided to patients by 10.5% of the practitioners. However, 55.6% addressed this issue if they considered the patient at risk for pregnancy. Only 33.2% of practitioners systematically referred the patient to a dentist. Periodontal disease knowledge and consideration levels increased in more experienced practitioners with a private practice and a personal history of periodontal disease. Periodontal knowledge of the French obstetricians and/or gynecologists surveyed seemed satisfyingly apparent and influenced by levels of professional experience and personal history. However, clinical behavior did not adequately correlate with this knowledge.

    Although many reports have been published on the functional roles of periodontal ligament (PDL) cells, the mechanisms involved in the maintenance and homeostasis of PDL have not been determined. We investigated the effects of biomechanical force on growth factor production, phosphorylation of MAPKs, and intracellular transduction pathways for growth factor production in human periodontal ligament (hPDL) cells using MAPK inhibitors. hPDL cells were exposed to mechanical force (6 MPa) using a hydrostatic pressure apparatus. The levels of growth factor mRNA and protein were examined by real-time RT-PCR and ELISA. The phosphorylation of MAPKs was measured using BD™ CBA Flex Set. In addition, MAPKs inhibitors were used to identify specific signal transduction pathways. Application of biomechanical force (equivalent to occlusal force) increased the synthesis of VEGF-A, FGF-2, and NGF. The application of biomechanical force increased the expression levels of phosphorylated ERK and p38, but not of JNK. Furthermore, the levels of VEGF-A and NGF expression were suppressed by ERK or p38 inhibitor. The growth factors induced by biomechanical force may play a role in the mechanisms of homeostasis of PDL.

    Periodontitis is one of the most widespread infectious diseases in humans. We previously promoted significant periodontal tissue regeneration in swine models with the transplantation of autologous periodontal ligament stem cells (PDLSCs) and PDLSC sheet. We also promoted periodontal tissue regeneration in a rat model with a local injection of allogeneic bone marrow mesenchymal stem cells. The purpose of the present study is to investigate the roles of the hepatocyte growth factor (HGF) and human dental pulp stem cells (DPSCs) in periodontal tissue regeneration in swine. In the present study, we transferred an adenovirus that carried HGF gene into human DPSCs (HGF-hDPSCs) under good manufacturing practice (GMP) conditions. These cells were then transplanted into a swine model for periodontal regeneration. Twenty miniature pigs were used to generate periodontitis with bone defect of 5 mm in width, 7 mm in length, and 3 mm in depth. After 12 weeks, clinical, radiological, quantitative and histological assessment of regenerated periodontal tissues was performed to compare periodontal regeneration in swine treated with cell implantation. Our study showed that injecting HGF-hDPSCs into this large animal model could significantly improve periodontal bone regeneration and soft tissue healing. A hDPSC or HGF-hDPSC sheet showed superior periodontal tissue regeneration compared to the injection of dissociated cells. However, the sheets required surgical placement; thus, they were suitable for surgically-managed periodontitis treatments. The adenovirus-mediated transfer of the HGF gene markedly decreased hDPSC apoptosis in a hypoxic environment or in serum-free medium, and it increased blood vessel regeneration. This study indicated that HGF-hDPSCs produced under GMP conditions significantly improved periodontal bone regeneration in swine; thus, this method represents a potential clinical application for periodontal regeneration.

    The purpose of the present study was to investigate the progression risk factors of periodontal disease by individual characteristics at baseline in a Greek adult population. The study sample consisted of 854 individuals. All participants were clinically examined and answered questions regarding sex, smoking status, socioeconomic status, low educational level, frequency of dental follow up, and oral hygiene habits. Serum levels of disease markers were investigated, and attachment levels were clinically recorded. For the assessment of periodontal disease progression, additional clinical attachment loss (CAL) was used if one or more sites showed a 3 mm or more increase in probing attachment level over a 2-year period. Statistical analysis was performed by using a modified multiple Poisson's analysis model. A total of 74% of the participants exhibited additional CAL over a 2-year period. Significant associations were observed between additional CAL and smoking (relative risk [RR] = 0.78, 95% confidence level [CI] = 0.65-0.92), attachment level of 5 mm or more at baseline (RR = 0.89, 95% CI = 0.75-1.05), educational level (RR = 0.90, 95% CI = 0.76-1.07), socioeconomic status (RR = 0.86, 95% CI = 0.59-1.14), and irregular dental follow up (RR = 1.23, 95% CI = 1.04-1.45). Smoking, baseline attachment level of 5 mm or more, low educational level, low socioeconomic status, and irregular dental follow up could be considered risk factors for further CAL. © 2015 Wiley Publishing Asia Pty Ltd.

    This study evaluates the expression of interleukin-18 (IL-18) and hypoxia-inducible factor (HIF)-lα in rat periodontitis model exposed to normoxia and chronic intermittent hypoxia (CIH) environments. The possible correlation between periodontitis and obstructive sleep apnea-hypopnea syndrome (OSAHS) was also investigated. Methods: Thirty-two Sprague-Dawley (SD) rats were randomly assigned into four groups: normoxia control, normoxia periodontitis, hypoxia control, and hypoxia periodontitis groups. The periodontitis models were established by ligating the bilateral maxillary second molars and employing high-carbohydrate diets. Rats in hypoxia control and hypoxia periodontitis groups were exposed to CIH treatment mimicking a moderately severe OSAHS condition. All animals were sacrificed after eight weeks, and the clinical periodontal indexes were detected. The levels of IL-18 and HIF-1α in serum and gingival tissues were determined using enzyme-linked immunosorbent assay (ELISA). The correlation between attachment loss (AL) and the levels of IL-18 and HIF-lα in hypoxia periodontitis group was evaluated. The levels of IL-18 and HIF-lα in hypoxia periodontitis group were significantly higher than that in normoxia periodontitis and hypoxia control groups (Pperiodontal tissues, which is correlated with IL-18 and HIF-lα levels.

    Full Text Available Several epidemiological evidence have been correlated with the effect of environmental factors over infectious diseases. Since the El Niño phenomenon in 1973, this event has been incriminated in the onset or trigger of epidemic changes and outbreaks. El Niño, which is responsible for the Ecuatorial Pacific Ocean water warming, produce a global effect, and as a consequence atmospheric humidity and environmental temperature are higher than usual. Currently, there are evidence that those changes have a direct effect on the biological life cycle of infectious diseases vectors and some microorganisms with a correlation in the epidemiology of those diseases. Recently, the molecular biology and the mathematical model analysis have been improving our understood about biological explanations, allowing the opportunity to predict outbreaks, risky areas, or epidemiological changes.

    Full Text Available A high percentage of prevalence of inflammatory periodontal diseases in young age causes urgency of treatment and prevention of inflammatory diseases of periodontal tissue in young age. Therefore, the research purpose was to investigate the hygienic condition and identification of the main risk factors for gingivitis in patients aged 18-30 years. 286 people aged from 18 to 30 years were observed in the study. To assess hygienic condition of the oral cavity and to determine the thickness of plaque indices OHI-S (simplified oral hygiene index Green Vermilyona and Silness Loe were used. Studies of oral hygiene status suggests that in patients with different etiologies of periodontal tissue inflammation, oral hygienic condition ranged from "satisfactory" to "poor." Therefore the results of study of hygiene and periodontal indices and samples confirmed presence of moderately expressed inflammation in the gums in young adults with chronic catarrhal gingivitis. Most often inflammation in the gums, namely, chronic catarrhal gingivitis was determined in patients with fixed prosthesis designs in the mouth or in violation of the bite, related to the major risk factors for periodontal disease occurring in young adults aged from 18 to 30 years.

    Periodontitis is a chronic infectious disease that leads to inflammation of the tissues supporting the teeth, bone loss, attachment loss progressively. In chronic periodontitis for starting the host response and inflammatory reaction, the presence of the infectious agent is necessary. One of inflammatory factors is tumor necrosis factor-alpha (TNF-α) that appear to be important in the destruction of periodontal tissues that were examined in this study. This study was performed in the laboratory and case-control study. The samples of study collected from 30 individuals with chronic periodontitis and 30 healthy controls that matched for age and sex, together. Unstimulated saliva samples were collected from patients and then TNF-α level were measured by enzyme-linked immunosorbent assay and were compared with the control group. In this study for statistical analysis, Mann-Whitney was used. There were differences in mean salivary concentrations of TNF-α in controls and patients. The average concentration in the case group was 9.1 (pg/ml) and the control group was 8.7 (pg/ml), but there was no significant difference between case and control groups (P > 0.05). The results of this analysis showed no significant relationship between two groups TNF-α concentration. This biomarker can not seem to be a good index to evaluate or predict periodontal disease.

    The number of graduates of U.S. dental schools enrolled in U.S. postdoctoral programs in periodontics has been decreasing. The aims of this study were to determine the perspectives of periodontics department chairs regarding 1) features of a school's predoctoral curriculum that promote student interest in advanced periodontal education and 2) characteristics of a periodontal residency program that make it more attractive to dental students over other specialty programs. In 2015, a 14-question survey was designed and sent to chairs of periodontics departments at all 65 U.S. dental schools at the time. Questions addressed number of instructional hours; specialty clinic rotations; elective courses; number of applicants to periodontal residency; existence of a residency program; length of the residency program; and externships, fellowships, and financial stipends offered. The survey response rate was 73.8%. The results showed that departments offering more than seven clinical credit hours in periodontics to predoctoral students had the greatest number of residency applicants. Most of the applicants were from institutions that offered specialty clinic rotations, elective courses, and residency programs in periodontics. The number of applicants did not change significantly if a stipend or fellowship was offered. However, the availability of an externship was significantly associated with a greater number of applicants (p=0.042). These results suggest that offering periodontal clinical rotations, elective courses, and especially externships in periodontics during predoctoral education may encourage more graduating students to pursue postdoctoral periodontal education.

    Periodontal disease is an inflammatory disease that has numerous consequences both locally and systemically The aim of this study was to assess whether periodontal disease causes systemic inflammatory response in otherwise healthy, adult dogs. We estimated the total mouth periodontal score (TMPS), measured the concentration of C-reactive protein (CRP), hematocrit, and albumin, and determined the white blood cell (WBC) and polymorphonuclear cell (PMN) counts in client-owned dogs. There was a statistically significant relationship between the gingival bleeding index (TMPS-G) and CRP concentration, and WBC and PMN counts, possibly during the active periods of periodontal tissue destruction. No correlation was found between the periodontal destruction index (TMPS-P) and the measured blood parameters. We conclude that chronic periodontal disease does not cause anemia or a reduction in serum albumin. However, active periods of periodontal inflammation may be associated with laboratory values suggestive of a systemic inflammatory response.

    Full Text Available El factor de crecimiento de fibroblastos 23 es una proteína recientemente descubierta, producida por osteocitos y cuya función principal es regular la homeostasis del fosfato y del calcio en el metabolismo mineral óseo. Algunos estudios han encontrado evidencia que sugiere la asociación entre el aumento de las concentraciones del factor de crecimiento fibroblástico 23 y la aparición de diferentes patologías cardiovasculares como: la hipertrofia ventricular izquierda, la falla cardiaca, el choque cardiogénico, la ateroesclerosis, la calcificación vascular, la fibrilación auricular y el accidente cerebrovascular. Sin embargo, son necesarios más estudios para esclarecer el rol de esta hormona y las patologías antes mencionadas.

    The aim of this study is the evaluation of levels of serum interleukin (IL)-1β, IL-6, IL-10, tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), placental growth factor (PIGF), and soluble VEGF receptor (sVEGFR)-1 and -2 in the association between periodontal disease and adverse pregnancy outcomes. One hundred and nine mothers, who recently gave birth, and 51 women who were not recently pregnant, aged 18 to 35 years, were included in this study. The mothers were classified as term birth, preterm birth (PTB), and preterm low birth weight (PLBW) in respect to their gestational age and baby's birth weight. The birth mothers were grouped as having gingivitis or periodontitis. The non-pregnant group also included periodontally healthy patients. Venous blood samples were collected to evaluate serum IL-1β, IL-6, IL-10, TNF-α, VEGF, PIGF, and sVEGFR-1 and -2 levels. Mother's weight, education, and income level were significantly associated with pregnancy outcomes. Serum levels of IL-1β, TNF-α, IL-6, VEGF, and sVEGFR-1 and -2 showed an increase in significance when related to pregnancy. Whereas in the PLBW group IL-1β, VEGF, and sVEGFR-2 levels were increased, in the PTB group sVEGFR-1 levels were increased. Additionally, the patients in the PLBW group with periodontitis had higher serum levels of IL-1β, VEGF, sVEGFR-2, and IL-1β/IL-10. The serum levels of IL-1β, VEGF, and sVEGFR-1 and -2 may have a potential effect on the mechanism of the association between periodontal disease and adverse pregnancy outcomes.

    Full Text Available There is little information about the knowledge and attitudes of physicians regarding oral care. This study aimed to assess the knowledge and attitudes of obstetricians about the relationship between periodontal disease and preterm/low birth weight. A questionnaire was emailed to members of the Brazilian Federation of Gynecology and Obstetrics (FEBRASGO. The questionnaire elicited both personal information and knowledge and attitudes regarding the relationship between periodontal diseases and preterm labor. A total of 875 obstetricians responded to the questionnaire. The majority of respondents were female (54.1%, resided in the Southeast (45.6%, worked in both the public and private sectors (61.4%, and had over 15 years of experience in obstetrics (48.9%. A large proportion of obstetricians (93.4% stated that bacteria were associated with periodontal disease, and 94% reported that periodontitis was a condition more severe than gingivitis. In total, over 80% of participating obstetricians reported smoking, preeclampsia, bacterial vaginosis and periodontal disease as risk factors or possible risk factors for preterm birth or low birth weight. A correlation between the experience of the obstetricians and referral of their patients for dental examinations (p < 0.001 was observed. Also, obstetricians who had had their own dental visits more recently were more likely to recommend the same for their patients (p < 0.001. It is concluded that, although obstetricians were aware of the association between gingival inflammation and adverse obstetric outcomes, the attitudes of these professionals were not in agreement with their apparent knowledge regarding periodontal diseases and their possible repercussions.

    Research highlights: → Concomitant use of FGF-2 and β-TCP (an osteo-conductive scaffold) significantly promotes periodontal regeneration in the severe periodontitis model (1-wall defect model) of beagle dog. → FGF-2 enhanced new bone formation via β-TCP at the defects. → In particular, FGF-2 dramatically regenerated new periodontal ligament and cementum formations at the defects, that is one of the most important healing outcomes during the process of periodontal regeneration. → Epithelial downgrowth (undesirable wound healing) was decreased by administration of FGF-2. → This manuscript indicates for the first time that concomitant use of FGF-2 and β-TCP is efficacious in regenerating periodontal tissue following severe destruction of the tissue by progression of periodontitis. -- Abstract: The effects of concomitant use of fibroblast growth factor-2 (FGF-2) and beta-tricalcium phosphate (β-TCP) on periodontal regeneration were investigated in the beagle dog 1-wall periodontal defect model. One-wall periodontal defects were created in the mesial portion of both sides of the mandibular first molars, and 0.3% FGF-2 plus β-TCP or β-TCP alone was administered. Radiographic evaluation was performed at 0, 3, and 6 weeks. At 6 weeks, the periodontium with the defect site was removed and histologically analyzed. Radiographic findings showed that co-administration of FGF-2 significantly increased bone mineral contents of the defect sites compared with β-TCP alone. Histologic analysis revealed that the length of the regenerated periodontal ligament, the cementum, distance to the junctional epithelium, new bone height, and area of newly formed bone were significantly increased in the FGF-2 group. No abnormal inflammatory response or ankylosis was observed in either group. These findings indicate the efficacy of concomitant use of FGF-2 and β-TCP as an osteoconductive material for periodontal regeneration following severe destruction by progressive

    2008-04-01

    Full Text Available El factor nuclear kB (NF-kB es un dímero constituido por proteínas de la familia Rel. El NF-kB se encuentra en el citoplasma unido a proteínas inhibidoras (IkB. Las IkB son fosforiladas por diferentes cinasas que hacen parte del signalosoma como las cinasas de IKKa e IKKb y el modulador esencial de NF-kB (NEMO, la proteína cinasa activadora de mitosis (MAPK o p38 y la cinasa inductora de NF-kB (NIK. Estas cinasas al ser activadas por señales dependientes de citocinas y luz ultravioleta, fosforilan las IkB provocando su ubiquitinación, su degradación por proteosoma y la subsecuente liberación y translocación al núcleo de NF-kB. Recientemente se le ha dado una gran importancia al NF-kB en la vía de señalización desencadenada por estrés oxidativo, estrés genotóxico y daño en el DNA. A diferencia de la vía denominada clásica, en esta ruta ocurre una SUMOilación de NEMO y translocación al núcleo. En el núcleo NEMO interactúa con la proteína de la ataxia telangiectasia mutada (ATM activada en respuesta a modificaciones en la cromatina y daño en el DNA. El complejo ATM/NEMO es translocado al citoplasma donde la ATM fosforila a las IKK llevando a la ubiquitinación y posterior liberación de NF-kB que es translocado al núcleo. NF-kB desencadena procesos de supervivencia incluyendo el aumento de la transcripción de enzimas antioxidantes como la superóxido dismutasa, catalasa y glutatión. Estas enzimas participan en el control de los niveles de especies reactivas de oxígeno en la célula. La sobreactivación de NF-kB se relaciona con inflamación y cáncer. En la actualidad se desarrolla una búsqueda de fármacos que actúen sobre moléculas del signalosoma de NF-kB, no sólo para el manejo de enfermedades inflamatorias sino también para el uso durante el tratamiento de tumores resistentes a radio y quimioterapia.

    Tumor necrosis factor (TNF)-α inhibitor has been shown to affect the periodontal condition of patients with rheumatoid arthritis (RA). The aim of the present study is to assess the effect of a fully humanized anti-TNF-α monoclonal antibody, adalimumab (ADA), on the periodontal condition of patients with RA and to compare serum protein profiles before and after ADA therapy. The study participants consisted of 20 patients with RA treated with ADA. Clinical periodontal and rheumatologic parameters and serum cytokine levels were evaluated at baseline and 3 months later. Serum protein spot volume was examined with two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis. Proteins with significant difference in abundance before and after ADA therapy were found and identified using mass spectrometry and protein databases. The patients showed a significant decrease in gingival index (P = 0.002), bleeding on probing (P = 0.003), probing depth (P = 0.002), disease activity score including 28 joints using C-reactive protein (P protein spots obtained, nine spots were significantly decreased in abundance at reassessment, corresponding to complement factor H, phospholipase D, serum amyloid A, complement component 4, and α-1-acid glycoprotein (P periodontal condition of patients with RA, which might be related to differences in serum protein profiles before and after ADA therapy.

    Objective To evaluate the prevalence of periodontal disease (PD) among Brazilian low-risk pregnant women and its association with sociodemographic factors, habits and oral hygiene. Method This cross-sectional study included 334 low-risk pregnant women divided in groups with or without PD. Indexes of plaque and gingival bleeding on probing, probing pocket depth, clinical attachment level and gingival recession were evaluated at one periodontal examination below 32 weeks of gestation. Independent variables were: age, race/color, schooling, marital status, parity, gestational age, smoking habit, alcohol and drugs consumption, use of medication, presence of any systemic diseases and BMI (body mass index). Statistical analyses provided prevalence ratios and their respective 95%CI and also a multivariate analysis. Results The prevalence of PD was 47% and significantly associated with higher gestational age (PR 1.40; 1.01 - 1.94 for 17-24 weeks and PR 1.52; 1.10 - 2.08 for 25-32 weeks), maternal age 25-29 years, obesity (PR 1.65; 1.02 - 2.68) and the presence of gingival bleeding on probing (ORadj 2.01, 95%CI 1.41 - 2.88). Poor oral hygiene was associated with PD by the mean values of plaque and bleeding on probing indexes significantly greater in PD group. Conclusions The prevalence of PD is high and associated with gingival bleeding on probing, more advanced gestational age and obesity. A program of oral health care should be included in prenatal care for early pregnancy, especially for low-income populations. PMID:22273008

    The effect of a common habit among Yemeni population on the periodontal status was investigated. This cross-sectional study was done on 2500 Yemenis with mean age 27.01 years (1818 males and 682 females). Among these 1528 were qat chewers and 972 were non-chewers. Detailed questionnaire and pre-designed scoring system for the periodontal status were employed for each case. Study results indicated that out of 972 non-chewers 116(12%) had periodontal pocketing and 18 (1.9%) cases had gingival recession. On the other hand, out of 1528 chewers, 468 (31.8%) had periodontal pockets and 98 (6.4%) with gum bleeding, p<0.05. These effects were found to increase with increased frequency and duration of chewing. It was concluded that habit of qat can cause damage to the periodontal ligament as pocketing and gum recession.

    Gingival and Periodontal diseases represent a major concern both in dentistry and medicine. The majority of the contributing factors and causes in the etiology of these diseases are reduced or treated with ozone in all its application forms (gas, water, oil). The beneficial biological effects of ozone, its anti-microbial activity, oxidation of bio-molecules precursors and microbial toxins implicated in periodontal diseases and its healing and tissue regeneration properties, make the use of ozone well indicated in all stages of gingival and periodontal diseases. The primary objective of this article is to provide a general review about the clinical applications of ozone in periodontics. The secondary objective is to summarize the available in vitro and in vivo studies in Periodontics in which ozone has been used. This objective would be of importance to future researchers in terms of what has been tried and what the potentials are for the clinical application of ozone in Periodontics.

    The aim of the study was to investigate the influence of local and general adverse risk factors and their role in the development of inflammatory periodontal diseases in children and adolescents. The study of the dental status among 618 school children, 9 to 15 years of age has been performed. The obtained results revealed an ambiguous influence of general and local risk factors on the development of inflammatory periodontal diseases. Namely, among the general risk factors the main role is given to hormonal functioning state of juvenile age (26.5%) - (arhythmia formation of hormonal activity). Among the local risk factors inducing inflammatory periodontal diseases at young age, the most significant are tooth-jaw anomalies (32.2%), especially - dental occlusion pathology, lips' bridle attachment anomalies, absence of interdental contacts, small vestibule of the mouth and so on. Poor oral hygiene, however, is also a significant factor in all age groups. Definition of the role and importance of general and local risk factors, taking into consideration patient's age, is of great importance in organization of early prevention, giving the possibility to predict disease possible development, choose most appropriate way to treat the specific situation, reduce the need of complex treatment and improve treatment outcomes.

    Full Text Available This study investigated some immunological features by experimental periodontitis (EP and rheumatoid arthritis (RA disease interact in destructive processes in arthritic rats. Rats were assigned to the following groups: EP +RA; RA; EP; and Negative Control. RA was induced by immunizations with type-II collagen and a local immunization with Complete Freund's adjuvant in the paw. Periodontitis was induced by ligating the right first molars. The serum level of rheumatoid factor (RF and anti-citrullinated protein antibody (ACCPA were measured before the induction of EP (T1 and at 28 days after (T2 by ELISA assay. ACCPA levels were also measured in the gingival tissue at T2. The specimens were processed for morphometric analysis of bone loss, and the gingival tissue surrounding the first molar was collected for the quantification of interleukin IL-1β, IL-4, IL-6, IL-17 and TNF-α using a Luminex/MAGpix assay. Paw edema was analyzed using a plethysmometer. Periodontitis increased the RF and ACCPA levels in the serum and in the gingival tissue, respectively. Besides, the level of paw swelling was increased by EP and remained in progress until the end of the experiment, when EP was associated with RA. Greater values of IL-17 were observed only when RA was present, in spite of PE. It can be concluded that periodontitis increases rheumatic factor serum levels and citrullinated proteins level in gingival tissues and alter cytokine balance in arthritic rats; at the same time, arthritis increases periodontal destruction, confirming the bidirectional interaction between diseases.

    The ultimate goal of periodontal therapy is the regeneration of the tissues destroyed as a result of periodontal disease. Currently, two clinical techniques, based on the principles of "guided tissue regeneration" (GTR) or utilization of the biologically active agent "enamel matrix derivative" (EMD), can be used for the regeneration of intrabony and Class II mandibular furcation periodontal defects. In cases where additional support and space-making requirements are necessary, both of these procedures can be combined with a bone replacement graft. There is no evidence that the combined use of GTR and EMD results in superior clinical results compared to the use of each material in isolation. Great variability in clinical outcomes has been reported in relation to the use of both EMD and GTR, and these procedures can be generally considered to be unpredictable. Careful case selection and treatment planning, including consideration of patient, tooth, site and surgical factors, is required in order to optimize the outcomes of treatment. There are limited data available for the clinical effectiveness of other biologically active molecules, such as growth factors and platelet concentrates, and although promising results have been reported, further clinical trials are required in order to confirm their effectiveness. Current active areas of research are centred on tissue engineering and gene therapy strategies which may result in more predictable regenerative outcomes in the future.

    Abstract Although the relationship between diabetes and periodontitis is well established, the association between periodontitis and prediabetes has been investigated less extensively. Furthermore, there has been little research on the prevalence of periodontitis among individuals with prediabetes and diabetes as well as in the overall population using nationally representative data. Among 12,406 adults (≥19 years’ old) who participated in the 2012–2013 Korea National Health and Nutrition Examination Survey, a total of 9977 subjects completed oral and laboratory examinations and were included in this analysis. Periodontitis was defined as a community periodontal index score of ≥3 according to the World Health Organization criteria. The fasting plasma glucose level was categorized into the following 5 groups: normal fasting glucose (NFG) 1 (periodontitis among the Korean adult population was 24.8% (23.3–26.4%) (weight n = 8,455,952/34,086,014). The unadjusted weighted prevalences of periodontitis were 16.7%, 22.8%, 29.6%, 40.7%, and 46.7% in the NFG 1, NFG 2, IFG 1, IFG 2, and diabetes groups, respectively (P periodontitis increased to 29.7% in the IFG 2 group (P = 0.045) and 32.5% in the diabetes group (P periodontitis with the above-mentioned variables as covariates were 1.42 (95% confidence interval [CI] 1.14–1.77, P = 0.002) in the diabetes group and 1.33 (95% CI 1.01–1.75, P = 0.044) in the IFG 2 group, respectively, compared with the NFG1 group. In conclusion, a higher range of IFG levels as well as diabetes, were positively associated with chronic periodontitis in a representative sample of Korean adults. This study suggests that individuals with a higher range of IFG levels before diabetes are at risk of periodontitis, and may benefit from dental screening. PMID:27057854

    Using data from the Third National Health and Nutrition Examination Survey (1988-1994), the authors examined the relation between periodontal health and cardiovascular risk factors: serum total and high density lipoprotein cholesterol, C-reactive protein, and plasma fibrinogen. A total of 10,146 participants were included in the analyses of cholesterol and C-reactive protein and 4,461 in the analyses of fibrinogen. Periodontal health indicators included the gingival bleeding index, calculus index, and periodontal disease status (defined by pocket depth and attachment loss). While cholesterol and fibrinogen were analyzed as continuous variables, C-reactive protein was dichotomized into two levels. The results show a significant relation between indicators of poor periodontal status and increased C-reactive protein and fibrinogen. The association between periodontal status and total cholesterol level is much weaker. No consistent association between periodontal status and high density lipoprotein cholesterol was detectable. Similar patterns of association were observed for participants aged 17-54 years and those 55 years and older. In conclusion, this study suggests that total cholesterol, C-reactive protein, and fibrinogen are possible intermediate factors that may link periodontal disease to elevated cardiovascular risk.

    Therapeutic concepts involving the application of matrix, growth and differentiation factors have been advocated in support of periodontal wound healing/regeneration. Growth/differentiation factor-5 (GDF-5), a member of the bone morphogenetic protein family, represents one such factor. The purpose of this review is to provide a background of the therapeutic effects of GDF-5 expressed in various musculoskeletal settings using small and large animal platforms. A comprehensive literature search was conducted to identify all reports in the English language evaluating GDF-5 using the PubMed and Google search engines, and a manual search of the reference lists from the electronically retrieved reports. Two reviewers independently screened the titles and abstracts from a total of 69 reports, 22 of which were identified as pre-clinical (in vivo) evaluations of GDF-5. The full-length article of the 22 pre-clinical reports was then reviewed. Various applications including cranial and craniofacial bone formation, spine fusion, long bone fracture healing, cartilage, and tendon/ligament repair using a variety of small and large animal platforms evaluating GDF-5 as a therapeutic agent were identified. A majority of studies, using biomechanical, radiographic, and histological analysis, demonstrated significant dose-dependent effects of GDF-5. These include increased/enhanced local bone formation, fracture healing/repair, and cartilage and tendon/ligament formation. GDF-5 frequently was shown to accelerate wound maturation. Several studies demonstrated GDF-5 to be a realistic alternative to autograft bone. Studies using pre-clinical models and human histology suggest GDF-5 may also increase/enhance periodontal wound healing/regeneration. GDF-5 appears a promising therapeutic agent for periodontal wound healing/regeneration as GDF-5 supports/accelerates bone and tendon/ligament formation in several musculoskeletal settings including periodontal tissues.

    Periodontal disease is a chronic disease causing an inflammatory process that affects various organs and is as-sociated with an increased risk of many diseases, including bone and cardiovascular disease. The aim of this study was to establish the prevalence of periodontal disease in continuous patients scheduled for hip or knee replacement surgery. The study was a prospective, epidemiological analysis performed in consecutive patients scheduled for total joint (hip or knee) replacement surgery. Patients enrolled into the study were screened for classical risk factors and had a dental evaluation performed for the diagnosis of periodontal disease. The study population consisted of 228 patients. A total of 137 (60.1%) patients were scheduled for a hip replace-ment surgery, while 91 (39.9%) had a knee replacement. The mean age of the study population was 66.8 ± 12.2 years, and 83 (36.4%) patients were male. A clinically significant disease was present in 65 (28.5%) cases, while all (100%) of the patients had at least minimal signs of periodontal disease. In patients with periodontal disease the percentage of tartar involvement of the teeth was 33.1 ± 26.8%, mean dental plaque coverage was 48.1 ± 29.8%, and bleeding occurred at a rate of 35.4 ± 29%. As for the hygiene level, it was generally poor in the majority of patients with periodontal disease. No differences in terms of baseline risk factors were present between patients with and without periodontal disease. In conclusion, periodontal diseases are highly prevalent in patients undergoing hip and/or knee replacement surgery. The presence of the periodontal disease is possibly associated with a worse prognosis and should be treated.

    Full Text Available Las enfermedades del sistema cardiovascular se constituyen en la principal causa de morbilidad y mortalidad en la población adulta de los países occidentales, sin embargo en la actualidad la incidencia de estas patologías en la población menor de 30 años esta alcanzando niveles alarmantes. Una de las explicaciones a este fenómeno es el aumento de actitudes que promueven los llamados factores de riesgo modificables como el sedentarismo, los malos hábitos alimenticios, el tabaquismo y el alcoholismo; lo anterior sumado a factores no modificables como la herencia y el género, contribuyen al desencadenamiento de las enfermedades cardiovasculares. Adicionalmente estas patologías fueron consideradas casi exclusivas de los países industrializados, sin embargo el problema se está expandiendo a los países en vía de desarrollo como Colombia, esto quizá producto del aumento en el ritmo de vida y a la adquisición de estilos de vida poco saludables El objetivo de este estudio fue investigar la presencia de factores de riesgo asociados con las enfermedades cardiovasculares en un grupo de estudiantes del programa de medicina de la Universidad del Magdalena, como parte de un trabajo de investigación formativa correspondiente a la cátedra de Bioquímica. Como resultado se encontró que el 24% de los sujetos investigados presentó niveles de colesterol total y LDL por encima de los parámetros seguros. Los factores de riesgo asociados con estos altos niveles fueron, los antecedentes familiares con un 83%y el sobrepeso con un 50%.

    Most studies comparing prevalence of periodontal disease and risk factors by using partial protocols were performed in adult populations, with several studies being conducted in clinical settings. The aim of this study is to assess the accuracy of partial protocols in estimating the prevalence of periodontal outcomes in adolescents and young adults from two population-based birth cohorts from Pelotas, Brazil, and to assess differences in the estimation and strength of the effect measures when partial protocols are adopted compared to full-mouth examination. Gingival bleeding at probing among adolescents (n = 339) and young adults (n = 720) and dental calculus and periodontal probing depth among young adults were assessed using full-mouth examinations and four partial protocols: Ramfjord teeth (RT), community periodontal index (CPI), and two random diagonal quadrants (1 and 3, 2 and 4). Socioeconomic, demographic, and periodontal health-related variables were also collected. Sensitivity, absolute and relative bias, and inflation factors were calculated. Prevalence ratio for each periodontal outcome for the risk factors was estimated. Two diagonal quadrants showed better accuracy; RT had the worst, whereas CPI presented an intermediate pattern when compared to full-mouth examination. For bleeding assessment in adolescence, RT and CPI underestimated by 18.4% and 16.2%, respectively, the true outcome prevalence, whereas among young adults, all partial protocols underestimated the prevalence. All partial protocols presented similar magnitude of association measures for all investigated periodontal potential risk factors. Two diagonal quadrants protocol may be effective in identifying the risk factors for the most relevant periodontal outcomes in adolescence and in young adulthood.

    Rui Vicente Oppermann

    2012-01-01

    Full Text Available Periodontal diseases comprise a number of infectious and inflammatory conditions brought about by the interaction between supragingival and subgingival biofilms and the host inflammatory response. Periodontal diseases should be considered systemic conditions. This means that they are both modulated by the body's systems and play a role as a risk factor for systemic derangements. The current evidence supports some of these interactions, such as smoking as a risk factor for periodontal disease and diabetes mellitus, as both influenced by and influencing inflammatory changes in the periodontal tissue. Other potential associations are still being researched, such as obesity, hormonal changes, cardiovascular disease, and adverse outcomes in pregnancy. These, and others, still require further investigation before the repercussions of periodontal disease can be fully elucidated. Nevertheless, at the present time, the treatment of periodontal diseases-and, most importantly, their prevention-enables adequate intervention as a means of ensuring periodontal health.

Además del número de repeticiones del triplete, existirían otros factores que explicarían el inicio de esta enfermedad a más temprana edad. Se sabe que la neuroinflamación es un protagonista en los trastornos neurodegenerativos, no siendo la enfermedad de Huntington una excepción. La neuroinflamación exacerba el daño neuronal producido por la mutación, al existir activación aberrante de la célula microglía, disfunción de astrocitos y células dendríticas; compromiso de la barrera hematoencefálica y activación de complemento, todas ellas como efecto directo e indirecto de la mutante y otros estímulos como infecciones crónicas. Es el interés del presente trabajo analizar la periodontitis, como modelo de infección bucodental crónica y fuente de inflamación sistémica. Hipotetizamos que el potencial rol de la periodontitis en la enfermedad de Huntington y los mecanismos por los cuales contribuiría a la manifestación temprana y progreso de dicha enfermedad, para lo cual se consideraron revisiones sistemáticas, metanálisis y estudios experimentales publicados tanto en español como en inglés obtenidos del PubMed y SciELO. Son diversos los mecanismos que generan inflamación en el cerebro de estos pacientes, adquiriendo especial protagonismo los mecanismos de la inmunidad innata. Las infecciones buco dentarias crónicas, como la enfermedad periodontal, pueden constituir un factor exacerbante de la neuroinflamación que per se asocia la enfermedad de Huntington.

    The current rapid progression in tissue engineering and local gene delivery system has enhanced our applications to periodontal tissue engineering. In this study, porous chitosan/collagen scaffolds were prepared through a freeze-drying process, and loaded with plasmid and adenoviral vector encoding human transforming growth factor-β1 (TGF-β1). These scaffolds were evaluated in vitro by analysis of microscopic structure, porosity, and cytocompatibility. Human periodontal ligament cells (HPLCs) were seeded in this scaffold, and gene transfection could be traced by green fluorescent protein (GFP). The expression of type I and type III collagen was detected with RT-PCR, and then these scaffolds were implanted subcutaneously into athymic mice. Results indicated that the pore diameter of the gene-combined scaffolds was lower than that of pure chitosan/collagen scaffold. The scaffold containing Ad-TGF-β1 exhibited the highest proliferation rate, and the expression of type I and type III collagen up-regulated in Ad-TGF-β1 scaffold. After implanted in vivo, EGFP-transfected HPLCs not only proliferated but also recruited surrounding tissue to grow in the scaffold. This study demonstrated the potential of chitosan/collagen scaffold combined Ad-TGF-β1 as a good substrate candidate in periodontal tissue engineering

    Full Text Available OBJETIVO: Estimar la carga de la enfermedad, su proporción atribuible a los principales factores de riesgo cardiovascular modificables y los costos médicos directos por hospitalización, asociados con las enfermedades coronarias y los accidentes cerebrovasculares en Argentina. MÉTODOS: Se elaboró un modelo analítico a partir de los datos de mortalidad en Argentina en 2005 y la prevalencia de los principales factores de riesgo cardiovascular (hipertensión arterial, hipercolesterolemia, sobrepeso, obesidad, hiperglucemia, tabaquismo actual y pasado, sedentarismo y consumo inadecuado de frutas y verduras. Se estimaron la carga de la enfermedad -años potenciales de vida perdidos (APVP y años de vida saludable (AVISA perdidos- y los costos de hospitalización por las enfermedades cardiovasculares analizadas. RESULTADOS: En 2005 se perdieron en Argentina más de 600 000 AVISA y se contabilizaron casi 400 000 APVP por enfermedades coronarias y accidentes cerebrovasculares; 71,1% de los AVISA perdidos, 73,9% de APVP y 76,0% de los costos asociados son atribuibles a facto-res de riesgo modificables. La hipertensión arterial fue el factor de riesgo de mayor impacto, tanto en hombres como en mujeres: 37,3% del costo total, 37,5% de los APVP y 36,6% de los AVISA perdidos. CONCLUSIONES: La mayor parte de la carga de la enfermedad en Argentina por enfermedades cardiovasculares está relacionada con factores de riesgo modificables -por lo tanto evitables- y podría reducirse mediante intervenciones poblacionales y clínicas basadas en un enfoque de riesgo, que ya han demostrado ser efectivas en función del costo, asequibles y factibles en países como Argentina.OBJETIVE: Estimate the burden of disease, the proportion attributable to the principal modifiable cardiovascular risk factors, and the direct medical cost of hospitalization associated with coronary heart disease and stroke in Argentina.

    The microflora, immunological profiles of host defence functions, and human leukocyte antigen (HLA) findings are reported for a mother, son and daughter who were diagnosed as having 'periodontitis as a manifestation of systemic diseases, associated with hematological disorders'. Examinations were made of the bacterial flora from the periodontal pocket, neutrophil chemotaxis, neutrophil phagocytosis, and the genotypes (DQB1) and serotypes (DR locus) of HLA class II antigens. Phenotypic analyses of the peripheral lymphocytes were also conducted. The subgingival microflora from the mother was dominated by Gram-negative rods, especially Porphyromonas endodontalis, Prevotella intermedia/Prevotella nigrescens and Fusobacterium nucleatum. Subgingival microflora samples from the son and daughter were dominated by Gram-positive cocci and Gram-positive rods. Through the use of polymerase chain reaction, Campylobacter rectus and Capnocytophaga gingivalis were detected in all subjects, whereas Porphyromonas gingivalis, P. intermedia, and Treponema denticola were not detected in any subjects. All three subjects showed a remarkable level of depressed neutrophil chemotaxis to N-formyl-methionyl-leucyl-phenylalanine, although their phagocyte function levels were normal, in comparison to healthy control subjects. Each subject had the same genotype, HLA-DQB1*0601, while the mother had HLA-DR2 and HLA-DR8, and the son and daughter had HLA-DR2 only. In summary, the members of this family showed a similar predisposition to periodontitis with regard to certain host defence functions. It is suggested that the depressed neutrophil chemotaxis that was identified here could be a significant risk factor for periodontitis in this family.

    Full Text Available Aims: Periodontal disease has been considered a systemic exposure implicated in a higher risk of adverse pregnancy outcomes. The aim of the present study was to determine whether maternal oral health is associated with an increased risk of pre-eclampsia. Subjects and Methods: A case-control study was conducted which included 40 pregnant women patients admitted to the Department of Obstetrics and Gynecology, J.N. Medical College, A.M.U, Aligarh. Pre-eclampsia was defined as classic triad of hypertension, proteinuria and symptoms such as swelling/edema esp. in hands and face, headache, visual changes etc., A periodontal examination was done during 48 h after child delivery. Maternal oral status was evaluated using gingival index by Loe and Silness, oral hygiene index (simplified by greene and vermillion and periodontal pockets and clinical attachment level (CAL. Statistical Analysis: Null hypothesis that no difference exist between the two groups (pre-eclamptic and non-pre-eclamptic Group was calculated using paired t-test, Chi-square and Mann-Whitney U statistical tests using SPSS 11.5 (Statistical Package for Social sciences, Chicago. P < 0.05 was considered to be statistically significant. Results: The amount of gingival inflammation, oral hygiene levels, pocket depth and CALs as measured by their respective indices were higher in the pre-eclamptic group when compared to non-pre-eclamptic group. Furthermore CAL was significantly increased in the test group. This study showed that pre-eclamptic cases were more likely to develop periodontal disease (P < 0.05. 30% of the test group and 65% of the case group had periodontal disease (P < 0.05 which had shown that pre-eclamptic cases were 4.33 times more likely to have periodontal disease (odds ratio = 4.33. Conclusions: Maternal oral status was determined to be associated with an increased risk of pre-eclampsia.

    Full Text Available Aims and Objectives : A relationship between poor periodontal health and respiratory disease has been suggested by a number of recent studies. The present study was undertaken to evaluate potential association between respiratory diseases and periodontal health status and to co-relate the severity of periodontal disease with that of chronic obstructive pulmonary disease (COPD. Materials and Methods : 150 patients of COPD (test group and 50 Patients without COPD (control group were recruited for the study. Information regarding patient′s demographic and socioeconomic status and lifestyle (history of smoking were considered in the study. Patients with COPD were grouped into mild, moderate and severe category on the basis of Spirometry. Periodontal health was assessed by measuring probing pocket depth, Clinical Attachment Loss (CAL and Oral Hygiene Index (OHI. Results : The results showed that the subjects with COPD had significantly more mean CAL and a higher mean OHI than those without COPD. The risk for COPD appeared to be significantly elevated when attachment loss was found to be severe. A trend was noted in that lung function appeared to diminish as the amount of attachment loss increased. Conclusion : On the basis of the observed results of the study it can be concluded that the risk for COPD appeared to be significantly elevated when attachment loss was found to be severe. It is conceivable that oral interventions that improve oral health status may prove to lower the severity of lung infection in susceptible populations.

    Full Text Available Abstract Background Information on the socio-behavioral distribution of periodontal status and tooth loss in pregnancy emanating from sub Saharan Africa is sparse. This study examined periodontal status and tooth loss in pregnant Ugandan women and assessed the relationship with socio-demographics factors, parity, dental care and oral hygiene. Methods Mothers were participants of a multicentre cluster-randomized behavioral intervention study (PROMISE-EBF Safety and Efficacy of Exclusive Breast feeding Promotion in the Era of HIV in Sub-Saharan Africa. In Uganda, these were pregnant women resident in Mbale district, recruited into the PROMISE EBF study between January 2006 and June 2008. A total of 886 women were eligible to participate of whom information became available for 877 (participation rate 98.9%, mean age 25.6 women who participated in the recruitment interview and 713 (mean age 25.5 women who got a clinical oral examination. Periodontal status was assessed using the Community Periodontal Index of Treatment Needs (CPITN. Results The prevalence of tooth loss was 35.7%, 0.6% presented with pockets shallow pockets (4–5 mm, whereas 3.3% and 63.4% displayed bleeding and calculus, respectively. A total of 32.7% were without any sign of periodontal disease. Binary logistic regression analyses revealed that older women, women from larger households and those presenting with microbial plaque were respectively, 3.4, 1.4 and 2.5 times more likely to have CPI score >0. Rural (OR = 0.9, nulliparous (OR = 0.4 and women who never visited a dentist (OR = 0.04 were less likely, whereas women from larger households (OR = 1.5 were more likely to have lost at least one tooth. Conclusion The results revealed moderate prevalence of bleeding and tooth loss, high prevalence of calculus, low frequency of pockets 4–5 mm. Disparity in pregnant women's oral health related to parity suggests that education of maternity care providers concerning oral health in

    Full Text Available Objectives: The purpose of this review was to evaluate whether history of periodontitis and smoking habits could represent a risk factor for peri-implantitis and implant loss. Material and Methods: This systematic review followed PRISMA guidelines and was registered at the PROSPERO database [registration numbers CRD42016034160 (effect of history of periodontitis and CRD42016033676 (effect of smoking]. Broad electronic (MEDLINE and manual searches were conducted among articles published from January 1st 1990 up to December 31st 2015, resulting in 49332 records for history of periodontitis and 3199 for smoking habits. Selection criteria included prospective studies comparing two cohorts of patients, with and without the investigated risk factor, with a minimum follow-up period of three years, and reporting data on peri-implantitis and implant loss occurrence. Considering that only prospective studies were included, dichotomous data were expressed as risk ratios and 95% confidence intervals. Results: Three studies evaluating history of periodontitis (on which quantitative analysis was performed and one study on smoking effect were included. Both implant and patient-based meta-analyses revealed a significantly higher risk of developing peri-implantitis in patients with a history of periodontitis compared with periodontally healthy subjects, but not a statistically significant increased risk for implant loss. Conclusions: The outcomes of this systematic review indicate history of periodontitis as a possible risk factor for peri-implantitis, while insufficient data are present in literature to evaluate the role of smoking. However, available evidence is still weak and immature, and sound epidemiological studies are needed to analyse the specific contribution of these potential risk factors.

    Full Text Available La periodontitis juvenil es una enfermedad del periodonto propia de adolescentes y adultos jóvenes, afecta principalmente los primeros molares y los incisivos y se caracteriza por la pérdida severa del hueso alveolar alrededor de dientes permanentes sin correspondencia entre la rapidez y severidad de la destrucción con los factores locales. En la causa de la enfermedad se citan factores genéticos, infecciosos e inmunológicos. Estudiamos algunos marcadores de inmunorrespuesta en 6 adolescentes que acudieron a nuestro servicio con el diagnóstico de periodontitis juvenil, además de su valoración clínica y radiológica. Ambos sexos se afectaron por igual, la movilidad dentaria y el sangramiento al sondeo fueron los hallazgos clínicos más relevantes y el índice de higiene bucal fue adecuado en todos los casos. No encontramos homogeneidad en las alteraciones inmunológicas, pero todos los pacientes estuvieron afectados en más de un marcador. Predominaron las alteraciones funcionales de linfocitos T en los estudios celulares. La hipogammaglobulinemia y la IgM elevada fueron las alteraciones más frecuentes en la inmunidad de anticuerpos. Se señala la dificultad que aún existe para explicar la patogenia de la enfermedad basándose solamente en un único factor de riesgo, así como la importancia de la valoración individual de cada enfermo.Juvenile periodontitis is a disease of the periodontium inherent to adolescents and young adults, affecting mainly the first molars and incisives and characterized by the severe loss of the alveolar bone sorrounding the permanent teeth with no correspondance between the celerity and severity of the destruction and the local factors.

    Recombinant human growth/differentiation factor-5 (rhGDF-5) in a particulate beta-tricalcium phosphate (beta-TCP) carrier is being evaluated to support periodontal regeneration. The objective of this study was to evaluate periodontal wound healing/regeneration following an established clinical (benchmark) protocol including surgical implantation of rhGDF-5/beta-TCP in comparison with that following implantation of recombinant human platelet-derived growth factor-BB (rhPDGF) combined with a particulate beta-TCP biomaterial using an established canine defect model. Bilateral, 4 x 5 mm (width x depth), one-wall, critical-size, intrabony periodontal defects were surgically created at the mandibular second and fourth pre-molar teeth in five adult Beagle dogs. Defect sites were randomized to receive rhGDF-5/beta-TCP or the rhPDGF construct followed by wound closure for primary intention healing. The animals were sacrificed following an 8-week healing interval for histological and histometric examination. Clinical healing was generally uneventful. Sites receiving rhGDF-5/beta-TCP exhibited a significantly enhanced cementum formation compared with sites receiving the rhPDGF construct, averaging (+/-SD) 4.49+/-0.48 versus 2.72+/-0.91 mm (palveolar bone. Both protocols displayed beta-TCP residues apparently undergoing resorption. Application of both materials appears safe, as they were associated with limited, if any, adverse events. rhGDF-5/beta-TCP shows a significant potential to support/accelerate periodontal wound healing/regeneration. Application of rhGDF-5/beta-TCP appears safe and should be further evaluated in human clinical trials.

    Mónica Sánchez-Aguilar

    Full Text Available Resumen Resumen: La industria de la construcción es sin lugar a dudas una de las mayores generadoras de riesgos de trabajo, sin embargo, los programas de prevención no hacen evidente dicha situación. Los trabajadores de la industria de la construcción laboran bajo condiciones precarias, carecen de seguridad social, y desconocen por completo los derechos que les son consignados por ley pese a no firmar un contrato. Es imprescindible que dichos trabajadores y los responsables de su actividad laboral, conozcan los factores de riesgo a que se encuentran expuestos, pero sobre todo las graves afecciones a la salud que estos pueden provocar, que van más allá de las lesiones músculo-esqueléticas incapacitantes tan reconocidas en bibliografía. Conforme se establezca la necesidad de un adecuado diagnóstico situacional al interior de las industrias, la prevención de patologías que hoy se consideran meramente generales y cuyo origen se encuentra en el desempeño del trabajo, encaminará a la salud pública a la adopción de políticas en mejora de las condiciones del mismo. Objetivo: Identificar las enfermedades actuales que se asocian a los factores de riesgo de la industria de la construcción en México. Material y Métodos: Revisión bibliográfica publicada desde enero del 2000 hasta noviembre del 2016 en bases de datos: PUBMED, SciELO y Medline. Se consultaron bibliografías tanto en inglés como en español. Las palabras clave consideradas en la búsqueda incluyeron: industria de la construcción, factores de riesgo, trabajo, enfermedades. Conclusiones: La industria de la construcción al presentar mayor cantidad de riesgos ergonómicos en México, debería ser una de las más estrechamente vigiladas, epidemiológicamente hablando, pues de ella derivan un gran número de enfermedades que aquejan a la población y que saturan diariamente al sistema de salud de nuestro país además de que afecta al desarrollo económico debido a la

    The present case-control study of 79 subjects (19-69 yr) was designed to assess the relationship of several psychological determinants to periodontal disease and obesity. Periodontal clinical examinations were performed, and the subjects were asked to complete a set of questionnaires measuring Type A personality, anxiety, depression, dental anxiety, hopelessness, emotional intelligence, stress, self-esteem, optimism and satisfaction with life. In a bivariate analysis, overweight individuals presented higher levels of smoking exposure, anxiety and depression and lower levels of optimism and satisfaction with life. They were mainly females, with a higher number of sites and teeth with probing depth (PD) >6 mm and clinical attachment level (CAL) >5 mm. Patients with a mean PD exceeding 3 mm and a bleeding on probing index of >25% presented higher values of dental anxiety and lower levels of self-esteem. Multiple linear regression analyses revealed that dental anxiety was positively associated with the number of teeth with a PD of >6 mm and with reasons for visiting a dentist, while satisfaction with life was associated with flossing frequency. We conclude that there is an association between several psychological determinants, periodontitis, and body mass index.

    2006-04-01

    Full Text Available Stress is hypothesized as a common pathway for several related chronic diseases of man. Psychosocial stress as modified by perceptions and coping by patients can lead to physical processes. Psychoneuroimmunologic (PNI studies have suggested that psychosocial stress can alter immune function and increase vulnerability to illnesses. The patients also have high sensitivity to periodontal disease (PD. This article describes the association of stress as a physiological response to diseases such as PD, rheumatoid arthritis (RA, and inflammatory bowel disease. The psychosocial stress can lead to physiological processes through 1 the hypothalamic-pituitary-adrenal (HPA axis leading to glucocortico-steroid secretion; 2 the autonomic nervous system, resulting in the release of catecholamine; or 3 the hypothalamic-pituitary-gonadal axis, resulting in the release of sex hormones. These processes may affect chronic diseases. It can be concluded that psychosocial stress in periodontal disease patients must be considered and social support must be provided in order to achieve an optimum periodontal therapy result.

Las formas más comunes son la diabetes tipo 11 o diabetes no insulino dependiente (DMNID y la tipo 1 (antigua juvenil o insulino-dependiente (DMID. Las más notables diferencias entre la frecuencia e intensidad de sus manifestaciones clínicas y complicaciones así como de su etiología son muy conocidas pero las anotaremos a manera de repaso.

    En la DMID o tipo 1 (la menos frecuente al menos dos genes localizados en el sistema HLA, región de antígenos de histocompatibilidad en el brazo corto del cromosoma 6, aumentan el riesgo. Se observa la presencia en el haplotipo de los antígenos B8/BWI5 y DW3/DW4. Posteriormente un virus (paperas, sarampión, mononucleosis, Cocksakie B desencadenarían una destrucción autoinmune de islotes!.

    En la DMNID o tipo II influyen la herencia y la obesidad como factores más notorios. Como en la DMID la producción de insulina es cerca a cero o cero, hay mayor tendencia a hiperglicemias marcadas, coma diabético y complicaciones microvasculares (nefropatía, retinopatía y neuropatía, pero también pueden haber complicaciones “macrovasculares” o aterogénicas, como enfermedad coronaria y arterioesclerosis periférica. La DMNID o tipo 11 presenta mayor incidencia de la última clase de complicaciones y menos de las primeras y generalmente hay “hiperinsulinemia” y obesidad asociadas. Los tipo 1generalmente mueren de falla renal y ciegos mientras los de tipo 11 mueren de infarto

    Como noticias recientes en diabetes, se ha comprobado que el control estricto de la hiperglicemia (manifestado por normalización de la hemoglobina glicosilada Al en la diabetes tipo 1previene o retarda la presencia de complicaciones microvasculares; esto se logra con un manejo intensivo, que incluye también uso intensivo de regímenes de insulina.

    Halitosis is a general term used to describe an unpleasant or offensive odor emanating from the oral cavity. It is a condition that has health and social implications in the life of those who suffer from it. The origin of halitosis is related to both systemic and oral conditions although the oral causes predominate. Volatile sulfur compound is the primary gas responsible for halitosis. They are formed as a result of gram-negative bacterial putrefaction. The major sites for oral halitosis are the dorsum of the tongue and periodontal pockets. There is a correlation between the amount of plaque on the tongue and periodontitis with the severity of halitosis. The aim of this article was to review the data and correlate periodontitis with severity of halitosis and the effect of halitosis- inducing factors on the progress of periodontal diseases. (author)

    Full Text Available Bajo la perspectiva del interaccionismo simbólico se analiza como influyen los factores del entorno en la relación de cuidado establecida por cuidadores primarios de personas con enfermedad mental severa en México. El cuidado se encuentra circunscrito al ámbito familiar dado el escaso desarrollo de una red social que proporcione los apoyos necesarios para favorecer la integración social. A esta situación han contribuido la naturalización cultural de los roles que desempeñan las mujeres como cuidadoras natas y las personas con enfermedad mental como dependientes, favoreciendo de esta forma la aceptación de alternativas como la institucionalización. La visualización del cuidado como responsabilidad individual favorece la situación de vulnerabilidad social, emocional y económica en la que se encuentran los cuidadores primarios y personas con enfermedad mental de este estudio.Under the perspective of symbolic interactionism analyzes how environmental factors influence the relationship of care provided by primary caregivers of people with severe mental illness in Mexico. The care is restricted to the family given the limited development of a social network to provide the necessary support to promote social integration. This situation has contributed the cultural naturalization of the roles that women plays as natural born caregivers and people with mental illness as a dependent person, consequently, encouraging the acceptance of alternatives such as institutionalization. The display of care as individual responsibility benefits the vulnerable social, emotional and economic situation, in which are the primary caregivers and people with mental illness in this study.

    Tannerella forsythia is a Gram-negative anaerobic organism that inhabits the subgingival cavity and initiates connective tissue destruction and alveolar bone resorption in periodontal disease (PD). PD is a chronic immunoinflammatory disease and has been linked to several systemic diseases including atherosclerosis. This study evaluated the effects of a chronic oral infection with T. forsythia ATCC 43037 on the induction of PD, inflammatory markers and atherosclerosis risk factors in hyperlipidemic ApoE(null) mice. Mice were orally infected for 12 and 24 weeks prior to euthanasia. Bacterial colonization of the oral cavity and bacteremia was confirmed via isolation of genomic DNA from oral plaque and tissues. Oral infection elicited significantly elevated levels of serum IgG and IgM antibodies and alveolar bone resorption compared to control mice. Tannerella forsythia-infected mice had increased serum amyloid A, and significantly reduced serum nitric oxide when compared to controls. Tannerella forsythia chronic infection also significantly increased serum lipoproteins suggesting altered cholesterol metabolism and potential for aortic inflammation. Despite enhanced acute phase reactants and altered lipid profiles, T. forsythia infection was associated with decreased aortic plaque. This study investigates the potential of a known periodontal bacterial pathogen found in atherosclerotic plaque in humans to accelerate atherosclerosis in hyperlipdemic mice. © FEMS 2015.

    Full Text Available Parkinson's disease (PD is a neurodegenerative disorder, predominantly characterized by the presence of motor symptoms. However, the non motor manifestations (NMM are a frequent complaint in the PD patients. There is a lack of information about the risk factors associated with the NMM in these patients. The aim of this study is to evaluate the prevalence of the more common NMM in a population of PD patients and to determine the features associated with its development. We studied 124 ambulatory PD patients. NMM were defined by the presence of neuropsychiatric manifestations, cognitive disorder, autonomic dysfunction or sleep related problems. In a multivariate analysis we found that the years of evolution of the PD and the presence of cognitive dysfunction are the risk factors for the neuropsychiatric and autonomic manifestations, whereas axial impairment is a risk factor for cognitive disorders and dyskinesias is for sleep related problems. In conclusion, this study shows that the features related to the PD progression appear as the main risk factors associated with NMM.La enfermedad de Parkinson (EP es un trastorno neurodegenerativo, caracterizado predominan-temente por la presencia de síntomas motores.

    Periodontal disease is a highly prevalent group of illnesses of microbial etiology, whose consequence is a severe breakdown of tooth-supporting structures. A link between periodontal infection and several systemic conditions, among which adverse pregnancy outcomes, has been suggested in the recent years. The aim of this review based on case-control studies was to evaluate if periodontal disease could be considered as a risk factor for preterm birth, low birth-weight and preterm low birth-weight. An electronic search (via Pubmed) was performed for case-control studies investigating the relationship between periodontal disease and adverse pregnancy outcomes. From the initially retrieved 417 articles, 17 case-control studies, accounting for a total of 10,148 patients, were included in the review and in the meta-analysis. The estimated odds ratio was 1.78 (CI 95%: 1.58, 2.01) for preterm birth, 1.82 (CI 95%: 1.51, 1.20) for low birth-weight and 3.00 (CI 95%: 1.93, 4.68) for preterm low birth-weight. Despite the results of the analysis of pooled data suggested a link between periodontal diseases and adverse pregnancy outcomes, the presence of important confounders, whose effect could not be addressed, prevents a validation of the meta-analysis outcomes. Further more accurate investigations based on individual data analysis could give a better insight into the topic of the present review.

    Several studies have suggested a link between periodontal disease and preterm birth, but the mechanism of how this occurs remains controversial. Therefore, this study aimed to investigate whether periodontal disease, defined according to two commonly used clinical definitions, is associated with preterm birth and to examine the association regarding oral health-related behaviors during pregnancy. This case-control study included women 18-40 years of age. Demographic and socio-economic data, information on current and previous pregnancies, and data on dental health-related behaviors and periodontal clinical parameters were collected within 48 h postpartum. Periodontal disease was assessed according to two definitions: four or more teeth with at least one site showing a probing depth of ≥ 4 mm and clinical attachment level of ≥ 3 mm (Definition 1); or at least one site with probing depth and clinical attachment level of ≥ 4 mm (Definition 2). The chi-square test was used to examine differences in the proportion of categorical variables. Bivariate analysis was performed to analyze the proportion of preterm births with respect to independent variables. Multiple logistic regression analyses were used to assess the association between periodontal disease and preterm birth. Odds ratios (ORs) were calculated with a 95% confidence interval (95% CI). A total of 296 postpartum women met the inclusion criteria. The case group included 74 women who delivered a preterm neonate (Periodontal disease according to Definition 1 was not associated with fewer weeks of gestation (adjusted OR (OR adjusted ) = 1.62; 95% CI = 0.80-3.29; p = 0.178). However, a significant association was found between periodontal disease, according to Definition 2, and preterm birth (OR adjusted = 1.98; 95% CI = 1.14-3.43; p = 0.015). Increased appetite and a low number of daily toothbrushings were associated with preterm birth, regardless of the definition of periodontal disease used. Periodontal

    Andrographolide is a herbal extract traditionally used in South Asian countries for treating inflammatory diseases. To evaluate the efficacy of andrographolide in management of periodontal disease which is a highly prevalent oral disease. Periodontal ligament fibroblasts (PDLF) were cultured from healthy and diseased periodontium using explant culture methods. The safe dose of AG was determined using MTT assay. LPS (lipopolysaccharide) of the most important periodontopathogen, P gingivalis was used to activate NF-κB and STAT3 in PDLF. The efficacy of AG in inhibiting NF-κB and STAT3 was analyzed using immunofluorescence. Down regulation of expression of target genes of these transcription factors related to inflammation and bone resorption were analyzed using real time PCR. AG up to the concentration of 25μM was found to be safe as determined by MTT assay. Statistically significant activation of NF-κB and STAT3 in cultured PDLF was observed in diseased group compared to healthy controls before and after LPS challenge. 5μM AG pretreatment significantly inhibited activation of NF-κB and STAT3 and down regulated expression of inflammatory and bone resorptive genes in cultured PDLF. The findings of the present study propose the adjunctive use of a novel herbal drug andrographolide as a promising host modulation agent for periodontal therapy by inhibiting NF-κB and STAT3 activation and inhibition of inflammation and bone resorption related genes.

    Full Text Available Periodontal disease can have significant effects by increasing the circulating levels of TNF-α, therefore its prevention and treatment is important in maintaining the overall health of the body. Objective: The aim of our research was to assess the differences in the salivary concentration of TNF-α between patients with periodontal disease and those free of the disease and to studz whether it can represent an indicator of the evolution of periodontal disease. We also aimed to assess the practical applicability of the method for the determination of this cytokine in the saliva. Materials and methods: Our study included two groups of subjects, the first group consisting in patients diagnosed with periodontal disease, while the control group included subjects free of periodontal disease. TNF-α concentration was determined with the ELISA test for human TNF-α and the results were expressed in pg/ mL. The data were statistically processed with GraphPad software and the statistical nonparametric Mann-Whitney test was applied. Results: We observe nearly double values of the TNF-α salivary level in the group of patients suffering from periodontal disease compared to the subjects free of periodontal disease, which allows us to notice that saliva analysis is a useful and safely enough method for the diagnosis and follow-up in the development of periodontal disease. Conclusion: The salivary level of TNF-α in patients with periodontal disease is not only an indicator of periodontal disease progression, but also a reflection of the pathogen potential that periodontal disease may have on the overall health of the body.

    Full Text Available Genetics is the study and understanding of the phenomena of heredity and variation. A large number of genes are associated with many systemic conditions. Periodontitis is inflammatory condition of periodontium. Periodontium consists of gingiva, periodontal ligament, cementum, and alveolar bone. It is considered being a multifactorial disease. Studies of animals and humans support the concept that a large number of genes' factor may be associated with periodontitis and clearly play a role in the predisposition and progression of periodontal diseases. It has been proven that genetic factors impair inflammatory and immune responses during periodontal diseases. Research on identifying specific genes causing periodontitis may improve and prevent the disease progression. The aim of this article is to focus on genetic risk factors and its influence for the various forms of periodontal disease.

    Among patients receiving clopidogrel for coronary artery disease, concomitant therapy with proton pump inhibitors (PPIs) has been associated with an increased risk for recurrent coronary events. Factores de Riesgo y ENfermedad Arterial (FRENA) is an ongoing, multicenter, observational registry of consecutive outpatients with coronary artery disease, cerebrovascular disease, or peripheral artery disease. We retrospectively examined the influence of concomitant use of PPIs on outcome in patients receiving clopidogrel. As of March 2009, 1222 patients were using clopidogrel: 595 had coronary artery disease, 329 cerebrovascular disease, and 298 had peripheral artery disease. Of these, 519 (42%) were concomitantly using PPIs. Over a mean follow-up of 15 months, 131 patients (11%) had 139 subsequent ischemic events: myocardial infarction 44, ischemic stroke 40, and critical limb ischemia 55. Seventeen of them (13%) died within 15 days of the subsequent event. PPI users had a higher incidence of myocardial infarction (rate ratio, 2.5; 95% confidence interval [CI], 1.3-4.8), ischemic stroke (rate ratio, 1.9; 95% CI, 1.03-3.7), and a nonsignificantly higher rate of critical limb ischemia (rate ratio, 1.6; 95% CI, 0.95-2.8) than nonusers. On multivariate analysis, concomitant use of clopidogrel and PPIs was independently associated with an increased risk for subsequent ischemic events both in the whole series of patients (hazard ratio, 1.8; 95% CI, 1.1-2.7) and in those with cerebrovascular disease or peripheral artery disease (hazard ratio, 1.5; 95% CI, 1.01-2.4). In patients with established arterial disease, concomitant use of PPIs and clopidogrel was associated with a nearly doubling of the incidence of subsequent myocardial infarction or ischemic stroke. This higher incidence persisted after multivariate adjustment.

    This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

    Full Text Available Diabetes mellitus is a systemic disease characterized by increased blood glucose levels and abnormalities of lipid metabolism due to absence or decreased level of insulin. It affects all the body organs and their functions either directly or indirectly. Every dentist should have a basic understanding of the etiopathogenesis, oral and systemic manifestations of this disease. The periodontal diseases are a consequence of extension of the gingival inflammation into the underlying supporting structures of the periodontium, initiated by the presence of plaque and its products on the surfaces of the teeth and the adjoining structures. The progression of periodontal disease is influenced by variety of factors like microorganisms, host response, systemic background, and genetic makeup of the host. Amongst them, diabetes mellitus tops the list. Diabetes and periodontitis influence the clinical outcome of each other and control of both influences the clinical improvement of each.

    Abstract Periodontitis is a systemic and chronic inflammatory disease associated with multiple physical conditions. Distress and depression are other problems affecting the progression of periodontitis. However, the causal relationship between depression and periodontitis has not been adequately investigated. This aim of this study was to determine the association between periodontitis and the subsequent development of depression. We identified 12,708 patients with newly diagnosed periodontitis from 2000 to 2005 and 50,832 frequency-matched individuals without periodontitis. Both groups were followed until diagnosed with depression, withdrawal from the National Health Insurance program, or the end of 2011. The association between periodontitis and depressio was analyzed using Cox proportional hazard regression models. The incidence density rate of depression was higher in the periodontitis group than in the nonperiodontitis group, with an adjusted hazard ratio of 1.73 (95% confidence interval 1.58–1.89) when adjusting for sex, age, and comorbidity. Cox models revealed that periodontitis was an independent risk factor for depression in patients, except for comorbidities of diabetes mellitus (DM), alcohol abuse, and cancer. Periodontitis may increase the risk of subsequent depression and was suggested an independent risk factor regardless of sex, age, and most comorbidities. However, DM, alcohol abuse, and cancer may prevent the development of subsequent depression because of DM treatment, the paradoxical effect of alcohol, and emotional distress to cancer, respectively. Prospective studies on the relationship between periodontitis and depression are warranted. PMID:26705230

    Recent studies have demonstrated the beneficial effects of omega-3 polyunsaturated fatty acids (PUFAs) on physiological processes and on a variety of chronic inflammatory diseases, including periodontal diseases. In this study, we evaluated the impact of omega-3 PUFAs in conjunction with scaling and root planing (SRP) on salivary markers in patients with chronic periodontitis. Thirty systemically healthy subjects with chronic periodontitis were enrolled and randomly allocated into two groups. The control group (n = 15) was treated with SRP + placebo whereas the test group was treated with SRP and dietary supplementation of low-dose omega-3 PUFAs (6.25 mg eicosapentaenoic acid and 19.19 mg docosahexaenoic acid). Clinical parameters were taken at baseline, 1, 3 and 6 mo following therapy. Saliva samples were obtained at the same time intervals and analyzed for tumor necrosis factor-α (TNF-α) and superoxide dismutase (SOD). Both groups showed significant changes in clinical parameters in response to treatment compared to baseline with no significant difference between groups. Salivary TNF-α levels showed a statistically significant decrease in the test group at 6 mo compared to the control group. Salivary SOD levels increased significantly at 3 and 6 mo in the test group and at 6 mo in placebo groups compared to baseline with no statistically significant differences between the groups. The results demonstrated that dietary supplementation with low-dose omega-3 PUFAs improves salivary TNF-α without any significant impact on clinical parameters in patients with chronic periodontitis, suggesting that the systemic benefits of dietary omega-3 PUFAs may not be translated to periodontal health.

    Según el diccionario de la Real Academia Española (11, divertículo, del latín, diverticulum, quiere decir desviación de un camino; y desde el punto de vista anatómico, apéndice hueco y terminado en fondo de saco. (Gráfica No. 1.

    Goligher (17 lo define como la “posada al borde del camino, probablemente un lugar, a menudo, de mala reputación”.

    Historia

    Según Hackford (18, el proceso fué descrito brevemente por Littre a comienzos del siglo XVIII; pero se le atribuye a Cruveilhier la primera descripción como proceso patológico en 1849, quien, además, mencionó: “encontramos, no rara vez, en el sigmoide, entre las bandas de fibras musculares longitudinales, una serie de pequeños tumores piriformes oscuros, que están formados por hernias de la mucosa a través de brechas en la capa muscular” (17.

    Fleischman en 1815 hizo la primera observación de la enfermedad y empleó el término divertículo (45.

    Rokitansky en 1.849, habló de una enfermedad adquirida y consideró que su causa consistía en la constipación (45.

    2013-06-01

    Full Text Available La enfermedad renal se ha convertido en una patología crónica de gran prevalencia en los países industrializados. Una modalidad de tratamiento sustitutivo renal es la hemodiálisis, para la cual es imprescindible tener un acceso vascular. Como acceso vascular de elección preferible al catéter venoso central, está la fístula arteriovenosa por haber demostrado menos complicaciones. Sin embargo, no está exenta de riesgos y dado que los problemas relacionados con el acceso vascular constituyen la primera causa de morbilidad y hospitalización, se pretendió estudiar aquellos factores de riesgo que influyen en la disfunción de las fístulas arteriovenosas. Material y métodos: Se trata de un diseño de caso-control en el que se comparó el grupo que presentó alguna disfunción de su fístula, ya fuera autóloga o protésica, con el que no presentó ninguna disfunción para analizar las diferencias entre ambos. Las variables se agruparon en tres apartados definidos para organizar los resultados y se estratificó por sexo, edad y por haber padecido o no disfunción de la fístula. Resultados: La edad y el sexo no influyen en padecer disfunción de la fístula sino que tiene más influencia la dislipemia, el haber comenzado tratamiento con hemodiálisis, el tipo de fístula y el haber portado catéter venoso central. Discusión: A diferencia de estudios publicados, en nuestra población no se han encontrado diferencias de disfunción de fístula en cuanto a edad y sexo. Sin embargo, se ha visto que hay menos riesgo de disfunción en aquellos pacientes con dislipemia, en los que su fístula es autóloga y en los que no han iniciado hemodiálisis o lo han hecho de manera programada y, por tanto, no han portado catéteres venosos centrales.

    Background: Periodontitis is a local inflammatory process mediating destruction of periodontium triggered by bacterial insult leading to systemic inflammatory mayhem in the host. Epidemiologically, it has been modestly associated with cardiovascular diseases (CVD) with elevated acute-phase reactant C-reactive protein (CRP) and rheological variables such as total leukocyte count and differential leukocyte count (TLC and DLC), which are potential predictors of CVD. Aim: The aim of this study was to investigate the serum CRP level, leukocyte count in chronic periodontitis patients and their relation to the severity of chronic periodontitis. Subjects and Methods: This cross-sectional study comprised 30 subjects, of which 20 were diagnosed as chronic periodontitis based on the Gingival index, probing depth and clinical attachment levels and 10 healthy subjects as controls. Following, which peripheral blood samples were drawn and serum CRP, TLC and DLC were quantified using the turbidimetric immunoassay. Data was analyzed using Intercooled Stata 9.2 version, (Stata corporation, LP, USA) ANOVA, Mann Whitney U test and Newman-Keuls post hoc procedures. P values less than) 0.05 were considered as significant Results: The mean serum CRP levels were statistically significant (P periodontitis subjects when compared with healthy controls. Leukocytes were significantly elevated in severe periodontitis compared with moderate periodontitis and controls; this finding was primarily explained by the increase in number of neutrophils. Conclusion: The increased serum CRP levels and neutrophils in chronic periodontitis subjects suggest an addition to the inflammatory burden of the individual potentially striking toward an increasing risk for cardiovascular events. Further research is needed to determine the specificity of these markers and their role in the inflammatory burden of one's systemic health. PMID:24971214

    Full Text Available Dental plaque is the primary etiological factor in periodontal diseases. However, there are many factors that can modify how an individual periodontal tissue will respond to the accumulation of dental plaque. Among such risk factors, there is increasing evidence that smoking tobacco products alters the expression and rate of progression of periodontal diseases. The aim of this study was to find out the loss of periodontal tissue adhesion in smokers by measuring pocket depth using probe, and by measuring alveolar bone damage using Bone Loss Score (BLS radiographic methods on teeth 12, 11, 21, 22, 32, 31, 41, 42. Based on T Test statistical analysis, there were significant differences in pocket depth damage of alveolar bone in smokers and non smokers.

    Full Text Available Periodontal diseases are among the most frequent diseases affecting children and adolescents. These include gingivitis, localized or generalized aggressive periodontitis (a.k.a., early onset periodontitis and periodontal diseases associated with systemic disorders. The effects of periodontal diseases observed in adults have earlier inception in life period. Gingival diseases in a child may progress to jeopardize the periodontium in adulthood. Therefore, periodontal diseases must be prevented and diagnosed early in the life. This paper reviews the most common periodontal diseases affecting children: chronic gingivitis (or dental plaque-induced gingival diseases and aggressive periodontitis. In addition, systemic diseases that affect the periodontium in young children and necrotizing periodontal diseases are addressed. The prevalence, diagnostic characteristics, microbiology, host- related factors, and therapeutic management of each of these disease entities are discussed.

    Full Text Available The periodontal disease is the most common disorder of oral cavity of the dogs, being characterized by the inflammation of the gingiva (gingivitis and periodontium (periodontitis, as a result of aerobic bacteria accumulation on the tooth surface, shaped as a biofilm, creating a microaerophilic environment that enhances the development of pathogenic anaerobic bacteria. The process of gingivitis can be reversed after proper treatment. If untreated, it progresses to periodontitis, an irreversible condition, because of the loss of epithelial adhesion. Animals with periodontitis have bone loss and consequently tooth mobility. This condition has the feeding as the main modifier factor. This means that the more solid is the food, the more friction with the tooth it will do, helping the removal of the biofilm. There are several predisposing factors of this disease, such as race, age, occlusion problems, immunodeficiency, among others. The clinical signs of periodontal disease may vary, being halitosis and gingivitis the most common findings. The diagnosis is made by direct inspection, where furcation exposure, inflammation and dental calculus can be seen. The best complementary tool to diagnose is the intra-oral radiography, which allows the visualization of bone structures that can not be seen during clinical inspection, helping to manage the treatment. The use of antibiotics is only complementary to treatment and only chosen in special cases. The treatment for this condition is surgical and requires sedation. It basically consists in the complete removal of dental calculus, followed by teeth polishing. The whole procedure is performed using specific techniques and instrumentation. There are various prophylactic methods, although daily brushing and the awareness of the owner about this condition are considered the ideal combination.

    Full Text Available Cyclic Neutropenia (CN is characterized by recurrent infections, fever, oral ulcerations, and severe periodontitis as result of the reduced host defences. The previous studies have established the effectiveness of recombinant granulocyte colony-stimulating factor (GCSF to increase the number and the function of neutrophils in the peripheral blood in this disease. In a 20-year-old Caucasian female with a diagnosis of cyclic neutropenia, oral clinical examination revealed multiple painful ulcerations of the oral mucosa, poor oral hygiene conditions, marginal gingivitis, and moderate periodontitis. The patient received a treatment with G-CSF (Pegfilgrastim, 6 mg/month in order to improve her immunological status. Once a month nonsurgical periodontal treatment was carefully performed when absolute neutrophil count (ANC was ≥500/L. The treatment with G-CSF resulted in a rapid increase of circulating neutrophils that, despite its short duration, leaded to a reduction in infection related events and the resolution of the multiple oral ulcerations. The disappearance of oral pain allowed an efficacy nonsurgical treatment and a normal tooth brushing that determined a reduction of probing depth (PD≤4 mm and an improvement of the oral hygiene conditions recorded at 6-month follow-up.

  19. Using risk assessment in periodontics.

    Risk assessment has become a regular feature in both dental practice and society as a whole, and principles used to assess risk in society are similar to those used in a clinical setting. Although the concept of risk assessment as a prognostic indicator for periodontal disease incidence and activity is well established in the management of periodontitis, the use of risk assessment to manage the practical treatment of periodontitis and its sequelae appears to have less foundation. A simple system of initial risk assessment - building on the use of the Basic Periodontal Examination (BPE), clinical, medical and social factors - is described, linked to protocols for delivering care suited to general dental practice and stressing the role of long-term supportive care. The risks of not treating the patient are considered, together with the possible causes of failure, and the problems of successful treatment are illustrated by the practical management of post-treatment recession.

    Full Text Available Evidence indicates that chronic infections and inflammation are associated with increased risk of cancer development. There has also been considerable evidence that proves the interrelationship between bacterial and viral infections and carcinogenesis. Periodontitis is a chronic oral infection thought to be caused by gram-negative anaerobic bacteria in the dental biofilm. Periodontal bacteria and viruses may act synergistically to cause periodontitis. Many studies have shown that periodontal pockets may act as reservoirs for human papilloma virus, cytomegalovirus, Epstein Barr virus, and suspected agents associated with oral cancer. Periodontitis, characterized by epithelial proliferation and migration, results in a chronic release of inflammatory cytokines, chemokines, growth factors, prostaglandins, and enzymes, all of which are associated with cancer development. This review article intends to shed light on the association between periodontal health and carcinogenesis.

    Full Text Available Periodontal health is influenced by a number of factors such as oral hygiene, genetic and epigenetic factors, systemic health, and nutrition. Many studies have observed that a balanced diet has an essential role in maintaining periodontal health. Additionally, the influences of nutritional supplements and dietary components have been known to affect healing after periodontal surgery. Studies have attempted to find a correlation between tooth loss, periodontal health, and nutrition. Moreover, bone formation and periodontal regeneration are also affected by numerous vitamins, minerals, and trace elements. The aim of this review is to critically appraise the currently available data on diet and maintenance of periodontal health and periodontal healing. The effects of nutritional intervention studies to improve the quality of life and well-being of patients with periodontal disease have been discussed.

    2008-09-01

    The aim of this review is to present the current status of the occurrence and management of a periodontal abscess during supportive periodontal therapy (SPT). A periodontal abscess depicts typical features and has been described in patients under SPT in clinical trials. Common periodontal pathogens have been observed in this lesion and some etiologic factors may be responsible for its recurrence. This condition can be isolated or associated with factors that can change the prognosis of affected teeth. Although it has been frequently noticed in untreated periodontitis, the periodontal abscess can also occur in patients under SPT and has been regarded as one of the possible complications of SPT. Patients with a high susceptibility to periodontal disease lost more teeth than those with a healthy periodontium. Early diagnosis and appropriate intervention for periodontal abscesses in patients under SPT are extremely important for the management of the periodontal abscess since this condition can lead to loss of the involved tooth. A single case of a tooth diagnosed with periodontal abscess that responds favorably to adequate treatment does not seem to affect its longevity. An accurate diagnosis and adequate treatment can preserve the longevity of affected teeth.

    Full Text Available Aim. The aim of this study was to determine tumor necrosis factor-alpha (TNF-α levels in periapical exudates and to evaluate their relationship with radiological findings. Methodology. Periapical exudates were collected from root canals of 60 single-rooted teeth using absorbent paper points. TNF-α levels were determined by enzyme-linked immunosorbent assays. The samples were divided into three groups according to the periapical radiolucent area. Results. Nonparametric Kruskal-Wallis test revealed significant differences between TNF-α concentrations in control group (40, 57±28, 15 pg/mL and group with larger radiolucent areas (2365, 79±582, 95 pg/mL, as well as between control and canals with small radiolucent areas (507, 66±278, 97 (P<.05. Conclusions. The levels of TNF-α increase significantly in teeth with periapical pathosis, from smaller to bigger lesions. This research and its results have shown that objective analysis of the TNF-α levels enables establishment of a relationship between different concentrations of TNF-α and different radiological changes.

    Definición
    La enfermedad de Hirschsprung, megacolon congénito o agangliónico, o Aganglionosis Intestinal Congénita, es una anomalía caracterizada por la ausencia congénita de células ganglionares del sistema parasimpático de los piejos intermientéricos de Auerbach, situado entre las capas musculares, circular y longitudinal, y el submucoso de Meissner; con conducción inefectiva del peristaltismo, ocasionando obstrucción funcional (24, 37, 65, 82, 120, 130, 134.

    Historia
    La descripción del megacolon congénito fue hecha por e! pediatra danés, HARALD HIRSCHSPRUNG, en 1886, en el Congreso de Pediatría de Berlín, donde describió dos casos, un niño de 7, Y otro de II meses de edad, quienes murieron, y al practicar la autopsia observó “dilatación enorme del colon”, con fecalomas en su interior y ulceraciones de la mucosa. Su informe apareció en la literatura médica un año después, en 1887.

    Sin embargo, la prime¡a anotación de esta alteración se le asigna a FREDERICK RUYSCH, quien en 1691, publicó en Amsterdam, en la Revista “Observationum AnatomiciChirurgicarum Centuria”, la descripción de la autopsia de una niña de cinco años quien había sido tratada por dolor y distensión abdominal, y flatos, finalmente murió; al abrir el cadáver pudo apreciar “todas las vísceras abdominales cubiertas por el colon distendido desde el recto”, descartó lo demás por considerarlo normal.

    Pustulosis palmaris et plantaris (PPP) is a chronic, inflammatory, autoimmune-type disease characterized by sterile pustules of skin. The skin inflammation is influenced by several factors such as drugs, sunlight, metabolic and psychogenic factors as well as metal allergy. Here, we report a rare case that intensive periodontal treatment might have contributed to the improvement of skin inflammation. Skin inflammation regressed 1 month after intensive periodontal treatment. Both CD4/CD8 ratio and % of B cells in the blood sample were slightly decreased corresponding to the improvement of periodontal inflammation. Infection control of periodontal lesions might be one of attractive therapeutic targets in management of PPP.

    Wang, Chin-Wei Jeff; McCauley, Laurie K

    2016-12-01

    Osteoporosis and periodontitis are both diseases characterized by bone resorption. Osteoporosis features systemic degenerative bone loss that leads to loss of skeletal cancellous microstructure and subsequent fracture, whereas periodontitis involves local inflammatory bone loss, following an infectious breach of the alveolar cortical bone, and it may result in tooth loss. Most cross-sectional studies have confirmed the association of osteoporosis and periodontitis primarily on radiographic measurements and to a lesser degree on clinical parameters. Multiple shared risk factors include age, genetics, hormonal change, smoking, as well as calcium and vitamin D deficiency. Both diseases could also be risk factors for each other and have a mutual impact that requires concomitant management. Suggested mechanisms underlying the linkage are disruption of the homeostasis concerning bone remodeling, hormonal balance, and inflammation resolution. A mutual interventional approach is emerging with complex treatment interactions. Prevention and management of both diseases require interdisciplinary approaches and warrants future well-controlled longitudinal and interventional studies for evidence-based clinical guidelines.

    There is a strong body of evidence to support the relationship between periodontal diseases and diabetes mellitus. Unless dental practitioners are aware of this link, they cannot apply the information to their daily practice. The aim of the study was, therefore, to evaluate the knowledge of dental practitioners concerning the effect of diabetes on periodontal health. This was a cross-sectional survey of randomly selected dental practitioners in Kuwait. Participants were asked about specific periodontal complications which they believed that patients diagnosed with diabetes were more susceptible to. A total of 220 dental practitioners (133 general dental practitioners and 87 dental specialists) participated in the study. Less than 60% of all study participants reported that tooth loss due to periodontal reasons and periodontal abscess were frequent among diabetic patients. Dental specialists, especially periodontists, were significantly more aware of periodontal complications associated with diabetes. Factors significantly associated with having knowledge about the effect of diabetes on periodontal health in logistic regression analysis were dentists who were older and those who were specialists. The results of this study indicate that knowledge about the effects of diabetes on periodontal health among this sample of dental practitioners is generally low, and dentists may underestimate the outcomes of periodontal diseases in diabetic patients.

    Full Text Available Chronic periodontitis is an infectious disease associated with the progressive destruction of periodontal tissues. In recent years, more and more data indicate an existing relationship between periodontal disease and rheumatoid arthritis. The link between both diseases has been confirmed in multiple studies. Despite the fact that this association might be based on shared environmental and genetic risk factors, a possible causal relation was advocated by experimental, epidemiological and interventional studies, with the leading role of Porphyromonas gingivalis. Individuals with chronic periodontitis are at an increased risk of developing rheumatoid arthritis, as well as rheumatoid arthritis patients are at an increased risk of chronic periodontitis and more severe forms of periodontitis. Furthermore, there is a correlation between the activity in both diseases – patients with more severe periodontitis suffer from more active rheumatoid arthritis. Intervention attempts were also performed, which demonstrated that eliminating periodontal infection and inflammation can affect the severity of rheumatoid arthritis. In this paper, we review the current knowledge about the link between both diseases, focusing on its clinical implications. Will periodontal treatment become a part of standard therapy for rheumatoid arthritis?

    Accumulated lines of evidence suggest that hyperimmune responses to periodontal bacteria result in the destruction of periodontal connective tissue and alveolar bone. The etiological roles of periodontal bacteria in the onset and progression of periodontal disease (PD) are well documented. However, the mechanism underlying the engagement of periodontal bacteria in RANKL-mediated alveolar bone resorption remains unclear. Therefore, this review article addresses three critical subjects. First, we discuss earlier studies of immune intervention, ultimately leading to the identification of bacteria-reactive lymphocytes as the cellular source of osteoclast-induction factor lymphokine (now called RANKL) in the context of periodontal bone resorption. Next, we consider (1) the effects of periodontal bacteria on RANKL production from a variety of adaptive immune effector cells, as well as fibroblasts, in inflamed periodontal tissue and (2) the bifunctional roles (upregulation vs. downregulation) of LPS produced from periodontal bacteria in a RANKL-induced osteoclast-signal pathway. Future studies in these two areas could lead to new therapeutic approaches for the management of PD by down-modulating RANKL production and/or RANKL-mediated osteoclastogenesis in the context of host immune responses against periodontal pathogenic bacteria.

    Periodontitis has been identified as a potential risk factor for systemic pathologies such as cardiovascular disease (CVD). The aims of this investigation were to assess the relationship between periodontitis and systemic inflammatory factor, as well as to discover whether there is a relation to the severity of periodontitis and to the periodontopathogens. Periodontal examinations and serum C-reactive protein (CRP) level measurements were performed in 50 patients with periodontitis. Periodontal health indicators included the gingival bleeding on probing index and periodontal disease status. The patients with moderate periodontitis had low attachment loss and pocket depth periodontitis had high attachment loss and pocket depth >5 mm. The control group comprised 25 volunteers with healthy gingiva, gingival sulcus periodontal parameters and CRP levels were significantly higher in the patients with periodontitis. Patients who had severe periodontitis, with high levels of mean clinical attachment loss, and subjects with moderate periodontitis had higher mean CRP levels. The percentage of subjects with elevated levels of CRP >5 mg/l was greater in the higher clinical attachment loss group compared to the group with lower attachment loss. The presence of P. gingivalis and A. actinomycetemcomitans were also associated with elevated CRP levels and poor periodontal status. Periodontitis and the presence of P. gingivalis are associated with an enhanced inflammatory response expressed by higher CRP levels. The association of periodontitis with CRP levels appears to be a contributing factor for CVD and might be a possible intermediate pathway in this association.

    Apical periodontitis is characterized by the presence of immunocompetent cells producing a wide variety of inflammatory mediators. Releasing cytokines with long-range action, such as interleukin-6 (IL-6) and granulocyte-macrophage colony-stimulating factor (GM-CSF), apical periodontitis may induce changes in remote organs of the host. This study quantified the levels of IL-6 and GM-CSF in symptomatic and asymptomatic human periradicular lesions. Lesions were also characterized by size and histologic findings. Tissue samples were homogenized and supernatants were assayed using an enzyme-linked immunosorbent assay (ELISA). Correlations between cytokine levels and characteristic features (as single variables) of the lesions were analysed. There was a trend for higher levels of IL-6 and GM-CSF in symptomatic than in asymptomatic lesions, but the difference was not significant. Levels also tended to be higher in large than in small lesions, in polymorphonuclear (PMN) cell-rich than in PMN cell-poor samples, and in epithelialized than in non-epithelialized lesions. Significantly higher levels of IL-6 (778.1 +/- 220.5 pg/microg) and GM-CSF (363.3 +/- 98.4 pg/microg) were found in samples coincidentally possessing symptomatic and epithelialized features than in asymptomatic, small, PMN cell-poor, non-epithelialized lesions (IL-6: 45.2 +/- 13.1 pg/microg and GM-CSF: 135.1 +/- 26.4 pg/microg). These results suggest that symptomatic lesions containing epithelial cells represent an immunologically active stage of apical periodontitis, whereas asymptomatic, small, PMN cell-poor, non-epithelialized lesions represent healing apical lesions.

    Endodontic-periodontal lesions present challenges to the clinician regarding diagnosis, treatment planning and prognosis. Etiologic factors, such as bacteria and viruses, as well as contributing factors, such as trauma, root resorptions, perforations, cracks and dental malformations, play an important role in the development and progression of such lesions. Treatment and prognosis of endodontic-periodontal lesions vary, depending on the etiology, pathogenesis and correct diagnosis of each specific condition. This chapter will appraise the interrelationship between endodontic and periodontal lesions and provide biological and clinical evidence for diagnosis, prognosis and decision-making in the treatment of these conditions. © 2017 John Wiley & Sons A/S.

    Full Text Available Periodontal disease is one of the risk factors for certain systemic conditions. Retrospective and prospective studies showed that pregnant women with periodontitis have significantly higher risk to deliver preterm low birth weight infants (gestation period < 37 weeks and birth weight < 2500 grams, and the risk increase as the periodontitis progressed during pregnancy. Periodontal disease could mediate this systemic effect through the action of periodontal pathogens and lipopolysaccharide increasing the production of prostaglandin and cytokine (physiologic mediators in parturition which will trigger the delivery of preterm low birth weight among women with periodontitis. It is concluded that periodontal disease is an independent risk factor for preterm low birth weight, and inclusion of oral prophylaxis procedure during pregnancy should be considered.

    The acute-phase response involves molecules including tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and C-reactive protein (CRP). This study aimed to determine whether subgingival scaling resulted in rapid changes in plasma concentrations of these molecules. Twenty-three non-smoking adults with chronic periodontitis received subgingival scaling for 60 minutes. Venous blood samples were taken at 0, 15, 30, 60, and 120 minutes. TNF-alpha and IL-6 were assayed from all samples and CRP from the baseline and final samples. Lipopolysaccharide (LPS) was assayed at 0, 15, and 30 minutes using limulus lysate assay (LAL) and EndoCAb Ig assays. LPS assays were suggestive of a transient low-grade bacteremia, but changes in LPS approaching significance (P=0.061) were seen with LAL only. There was a significant increase in circulating TNF-alpha (P=0.0387) and IL-6 (Pperiodontal breakdown (P=0.001). There was also a significant correlation between levels of IL-6 and TNF-alpha (Pperiodontitis patients undergoing an episode of subgingival scaling show a significant elevation in circulating TNF-alpha and IL-6. This may account for anecdotal reports of pyrexia following treatment and may be significant in terms of the relationship between periodontal disease, bacteremia, and cardiovascular disease.

    Mani Ameet M, Mani Shubhangi A, Tejnani Avneesh H, Gupta Ankit

    2013-04-01

    Full Text Available It is now well established that tobacco use in general and cigarette smoking in particular, is a major risk factor in the incidence and severity of several forms of periodontal diseases.A large number of studies have been published in the dental literature regarding this possible role. Much of the literature has also indicated that smokers affected with periodontitis respond less favourably to periodontal treatment be it non-surgical, surgical or regenerative. Numerous studies of the potential mechanisms whereby smoking tobacco may predispose to periodontal disease have been conducted, and it appears that smoking may affect the vasculature, the humoral immune system, and the cellular immune and inflammatory systems, and have effects throughout the cytokine and adhesion molecule network. The aim of this review is to consider the evidence for the association between smoking and periodontal diseases and to highlight the biological mechanisms whereby smoking may affect the periodontium.

    During the last three to four decades, extensive changes in opinion concerning the etiology, pathogenesis, and treatment of periodontal disease have taken place. During these decades, contributing factors are standardized and controlled trials, as well as epidemiological studies, were performed. Periodontics is no longer an art as it was at the end of the 19th century- it is a science based on research. Pyorrhea alveoiaris or periodontitis has been considered a multifactorial disease with bad prognosis which, together with caries, causes loss of teeth in the population. It was supposed to affect most of the population with age progress, trauma from occlusion, systemic diseases, and bad oral hygiene. The discovery that plaque was the cause of gingivitis, and that the subgingival microflora differed in composition between sites, teeth, and individuals created new suggestions and demands for the treatment of periodontal disease. The aim of this paper is to summarize some modern aspects on periodontal disease. (author)

    Recombinant human growth/differentiation factor-5 (rhGDF-5) is being evaluated as a candidate therapy in support of periodontal regeneration. The objective of this study was to evaluate cementum and alveolar bone formation, and aberrant healing events following surgical implantation of rhGDF-5 in an absorbable collagen sponge (ACS) carrier using an established periodontal defect model. Bilateral 4 x 5 mm (width x depth), one-wall, critical-size, intrabony periodontal defects were surgically created at the mandibular second and fourth pre-molar teeth in 15 Beagle dogs. Five animals received 1 microg/defect and five animals 20 microg/defect rhGDF-5 in unilateral defect sites. Contralateral sites received treatments reported elsewhere. Five animals received rhGDF-5/ACS with 0 (buffer control) and 100 microg/defect rhGDF-5 in contralateral defect sites. The animals were euthanized at 8 weeks post-surgery for histologic and histometric evaluation. Surgical implantation of rhGDF-5 stimulated significant periodontal regeneration. Cementum formation was significantly enhanced in sites implanted with rhGDF-5 (1 and 100 microg) compared with control (phealing/regeneration in intrabony periodontal defects without complications.

    Physiologic and metabolic changes that occur immediately after a damage or disease are known as Acute Phase Reaction (APR). Acute Phase Proteins (APP) are blood proteins secreted by hepatocytes during APR C-Reactive Protein (CRP) being the important one. Present study was designed to estimate and compare the levels of the serum CRP in current smokers, former smokers and non-smokers, with and without periodontitis. An experimental study was planned on 165 subjects who were divided into four groups. Group 1- nonsmokers with periodontitis. Group 2- smokers without periodontitis. Group 3- smokers with periodontitis. Group 4- former smokers without periodontitis. Healthy controls were not included in the study as the normal range of CRP in health is already established. Periodontal examination was done and serum CRP was measured. After getting the acceptance to be a part of the study, written informed consent was taken from each participant. Data analysis was done by ANOVA and post-hoc tests. Highest level of CRP was found in smokers with periodontitis followed by non-smokers with periodontitis and smokers without periodontitis. Former smokers had minimum CRP compared to the other groups (p-value=0.03). Periodontitis alone and in combination with smoking increases the systemic inflammatory burden and associated cardiovascular risk. This fact should be communicated thoroughly to the general population, general dentist, physicians and cardiovascular specialist to enhance early screening and multidisciplinary treatment.

  1. The periodontal pain paradox: Difficulty on pain assesment in dental patients (The periodontal pain paradox hypothesis

    Haryono Utomo

    2006-12-01

    Full Text Available In daily dental practice, the majority of patients’ main complaints are related to pain. Most patients assume that all pains inside the oral cavity originated from the tooth. One particular case is thermal sensitivity; sometimes patients were being able to point the site of pain, although there is neither visible caries nor secondary caries in dental radiograph. In this case, gingival recession and dentin hypersensitivity are first to be treated to eliminate the pain. If these treatments failed, pain may misdiagnose as pulpal inflammation and lead to unnecessary root canal treatment. Study in pain during periodontal instrumentation of plaque-related periodontitis revealed that the majority of patients feel pain and discomfort during probing and scaling. It seems obvious because an inflammation, either acute or chronic is related to a lowered pain threshold. However, in contrast, in this case report, patient suffered from chronic gingivitis and thermal sensitivity experienced a relative pain-free sensation during probing and scaling. Lowered pain threshold which accompanied by a blunted pain perception upon periodontal instrumentation is proposed to be termed as the periodontal pain paradox. The objective of this study is to reveal the possibility of certain factors in periodontal inflammation which may involved in the periodontal pain paradox hypothesis. Patient with thermal hypersensitivity who was conducted probing and scaling, after the relative pain-free instrumentation, thermal hypersensitivity rapidly disappeared. Based on the successful periodontal treatment, it is concluded that chronic gingivitis may modulate periodontal pain perception which termed as periodontal pain paradox

    Mangiferin is a natural polyphenol compound with anti-inflammatory properties. However, there have been few reports on the effect of mangiferin on periodontitis. Here, we investigated the anti-inflammatory effects of this compound on experimental periodontitis and the underlying mechanisms. Mice were inoculated with Porphyromonas gingivalis to induce periodontitis, and treated with mangiferin orally (50 mg/kg bodyweight, once a day) for 8 wk. Then, the alveolar bone loss was examined using a scanning electronic microscope. Expression of tumor necrosis factor-α (TNF-α) and the phosphorylation levels of nuclear factor-κB (NF-κB) and Janus kinase 1-signal transducer and activator of adhesion (JAK1-STAT) pathways in the gingival epithelium were detected using western blot analysis and immunohistochemical staining. The results showed that mice with periodontitis exhibited greater alveolar bone loss, stronger expression of TNF-α and higher phosphorylation levels of NF-κB and JAK1-STAT1/3 pathways in gingival epithelia, compared with control mice with no periodontitis. Moreover, treatment with mangiferin could significantly inhibit alveolar bone loss, TNF-α production and phosphorylation of NF-κB and JAK1-STAT1/3 pathways in gingival epithelia. Mangiferin has anti-inflammatory effects on periodontitis, which is associated with its ability to down-regulate the phosphorylation of NF-κB and JAK1-STAT1/3 pathways in gingival epithelia. © 2016 John Wiley & Sons A/S.

    Periodontal disease is among the most common inflammatory conditions which is associated with many different factors. One of the contributing factors to the pathogenesis of this condition may compromise the defensive mechanism of antioxidants. The present study evaluates the antioxidant capacity of saliva in periodontal patients before and after periodontal treatment. In this cross sectional study, 31 patients systemically healthy non smokers with chronic periodontitis were recruited. The antioxidant capacity of saliva was measured before the initial phase of periodontal therapy and after completion of the treatment. Data were analyzed using SPSS 19 software. Paired T-Test, Independent sample T-test and ANOVA tests were used as appropriated. The mean and standard deviation antioxidant capacity of the saliva after the treatment.(0.962± 0.287µM)was significantly higher than before the treatment (0.655 ± 0.281 µM ,pperiodontal treatment was higher among men than among women; however, the difference was not significant (P=0.07). The mean difference of salivary antioxidant capacity was not significantly differed among different ages (P=0.772). The antioxidant capacity of saliva was higher after periodontal therapy among patients with periodontal disease, however the change was not varied across the ages and gender. Therefore, the alterations in the defensive mechanism of antioxidants could be the key factors contribute to the pathogenesis of periodontal diseases.

    Full Text Available Las enfermedades pulmonares intersticiales en el niño, comprenden un gran y heterogéneo grupo de raras enfermedades difusas pulmonares de morbilidad variada. Se caracterizan por cambios inflamatorios y fibróticos que causan remodelación de las paredes alveolares y de las vías respiratorias distales, y ocasionan un defecto restrictivo funcional y una alteración en el intercambio gaseoso, con hipoxemia progresiva. Son muchas las enfermedades que pueden afectar al intersticio pulmonar y múltiples las formas etiológicas causadas por una variedad de procesos patológicos, que incluyen, factores genéticos, asociación a enfermedades sistémicas, así como a respuestas inflamatorias o fibróticas a diferentes estímulos. Sin embargo, algunas veces su origen es desconocido, y se catalogan entonces como idiopáticas. Los neumólogos pediátricos han tratado de clasificar los casos de las enfermedades pulmonares intersticiales en las diferentes categorías descritas originalmente en adultos, pero, en realidad, existen formas del adulto que no se observan en la infancia, y formas únicas de presentación pediátrica. Se señala la importancia del conocimiento de estas entidades, particularmente las de origen desconocido o idiopáticas.

    Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual. However, a subgroup of these diseases include aggressive and acute forms that have a relatively low prevalence but show a rapid-course, high rate of progression leading to severe destruction of the periodontal tissues, or cause systemic symptoms that often require urgent attention from healthcare providers. Aggressive periodontitis is an early-onset, destructive disease that shows a high rate of periodontal progression and distinctive clinical features. A contemporary case definition of this disease is presented. Population studies show that the disease is more prevalent in certain geographic regions and ethnic groups. Aggressive periodontitis is an infectious disease, and recent data show that in affected subjects the subgingival microbiota is composed of a mixed microbial infection, with a wide heterogeneity in the types and proportions of microorganisms recovered. Furthermore, there are significant differences in the microbiota of the disease among different geographic regions and ethnicities. There is also evidence that the Aggregatibacter actinomycetemycomitans-JP2 clone may play an important role in the development of the disease in certain populations. The host response plays an important role in the susceptibility to aggressive periodontitis, where the immune response may be complex and involve multiple mechanisms. Also, genetic factors seem to play an important role in the pathogenesis of this disease, but the mechanisms of increased susceptibility are complex and not yet fully understood. The available data suggest that aggressive periodontitis is caused by mutations either in a few major genes or in multiple small-effect genes, and there is also evidence of gene-gene and gene-environment interaction effects. Diagnostic methods for this disease, based on a specific microbiologic, immunologic or

    Gingivitis and periodontitis are immunoinflammatory periodontal diseases characterized by chronic localized infections usually associated with insidious inflammation This narrative review discusses periodontal diseases and mechanisms influencing the immune response and autoimmunity in pediatric rheumatic diseases (PRD), particularly juvenile idiopathic arthritis (JIA), childhood-onset systemic lupus erythematosus (C-SLE) and juvenile dermatomyositis (JDM). Gingivitis was more frequently observed in these diseases compared to health controls, whereas periodontitis was a rare finding. In JIA patients, gingivitis and periodontitis were related to mechanical factors, chronic arthritis with functional disability, dysregulation of the immunoinflammatory response, diet and drugs, mainly corticosteroids and cyclosporine. In C-SLE, gingivitis was associated with longer disease period, high doses of corticosteroids, B-cell hyperactivation and immunoglobulin G elevation. There are scarce data on periodontal diseases in JDM population, and a unique gingival pattern, characterized by gingival erythema, capillary dilation and bush-loop formation, was observed in active patients. In conclusion, gingivitis was the most common periodontal disease in PRD. The observed association with disease activity reinforces the need for future studies to determine if resolution of this complication will influence disease course or severity.

    The oral cavity is a part of the body. The health of the oral cavity affects the health of the entire body. This relationship is reciprocal, as the overall health of an individual will also affect the health of that individual's oral cavity. Periodontal disease is a common, chronic inflammatory disease affecting the supporting structures of the teeth. It has been proposed that periodontal disease is a risk factor for systemic diseases such as diabetes.

    The microorganisms that form dental plaque are the main cause of periodontitis. Their identification and the understanding of the complex relationships and interactions that involve these microorganisms, environmental factors and the host's health status enable improvement in diagnostics and targeted therapy in patients with periodontitis. To this end, molecular diagnostics techniques (both techniques based on the polymerase chain reaction and those involving nucleic acid analysis via hybridization) come increasingly into use. On the basis of a literature review, the following methods are presented: polymerase chain reaction (PCR), real-time polymerase chain reaction (real-time PCR), 16S rRNA-encoding gene sequencing, checkerboard and reverse-capture checkerboard hybridization, microarrays, denaturing gradient gel electrophoresis (DGGE), temperature gradient gel electrophoresis (TGGE), as well as terminal restriction fragment length polymorphism (TRFLP) and next generation sequencing (NGS). The advantages and drawbacks of each method in the examination of periopathogens are indicated. The techniques listed above allow fast detection of even small quantities of pathogen present in diagnostic material and prove particularly useful to detect microorganisms that are difficult or impossible to grow in a laboratory.

    Full Text Available Abstract Background In periodontitis, treatment aimed at controlling the periodontal biofilm infection results in a resolution of the clinical and histological signs of inflammation. Although the cell types found in periodontal tissues following treatment have been well described, information on gene expression is limited to few candidate genes. Therefore, the aim of the study was to determine the expression profiles of immune and inflammatory genes in periodontal tissues from sites with severe chronic periodontitis following periodontal therapy in order to identify genes involved in tissue homeostasis. Gingival biopsies from 12 patients with severe chronic periodontitis were taken six to eight weeks following non-surgical periodontal therapy, and from 11 healthy controls. As internal standard, RNA of an immortalized human keratinocyte line (HaCaT was used. Total RNA was subjected to gene expression profiling using a commercially available microarray system focusing on inflammation-related genes. Post-hoc confirmation of selected genes was done by Realtime-PCR. Results Out of the 136 genes analyzed, the 5% most strongly expressed genes compared to healthy controls were Interleukin-12A (IL-12A, Versican (CSPG-2, Matrixmetalloproteinase-1 (MMP-1, Down syndrome critical region protein-1 (DSCR-1, Macrophage inflammatory protein-2β (Cxcl-3, Inhibitor of apoptosis protein-1 (BIRC-1, Cluster of differentiation antigen 38 (CD38, Regulator of G-protein signalling-1 (RGS-1, and Finkel-Biskis-Jinkins murine osteosarcoma virus oncogene (C-FOS; the 5% least strongly expressed genes were Receptor-interacting Serine/Threonine Kinase-2 (RIP-2, Complement component 3 (C3, Prostaglandin-endoperoxide synthase-2 (COX-2, Interleukin-8 (IL-8, Endothelin-1 (EDN-1, Plasminogen activator inhibitor type-2 (PAI-2, Matrix-metalloproteinase-14 (MMP-14, and Interferon regulating factor-7 (IRF-7.

    This volume of Periodontology 2000 represents the 25th anniversary of the Journal, and uses the occasion to assess important advancements in periodontology over the past quarter-century as well as the hurdles that remain. Periodontitis is defined by pathologic loss of the periodontal ligament and alveolar bone. The disease involves complex dynamic interactions among active herpesviruses, specific bacterial pathogens and destructive immune responses. Periodontal diagnostics is currently based on clinical rather than etiologic criteria, and provides limited therapeutic guidance. Periodontal causative treatment consists of scaling, antiseptic rinses and occasionally systemic antibiotics, and surgical intervention has been de-emphasized, except perhaps for the most advanced types of periodontitis. Plastic surgical therapy includes soft-tissue grafting to cover exposed root surfaces and bone grafting to provide support for implants. Dental implants are used to replace severely diseased or missing teeth, but implant overuse is of concern. The utility of laser treatment for periodontitis remains unresolved. Host modulation and risk-factor modification therapies may benefit select patient groups. Patient self-care is a critical part of periodontal health care, and twice-weekly oral rinsing with 0.10-0.25% sodium hypochlorite constitutes a valuable adjunct to conventional anti-plaque and anti-gingivitis treatments. A link between periodontal herpesviruses and systemic diseases is a strong biological plausibility. In summary, research during the past 25 years has significantly changed our concepts of periodontitis pathobiology and has produced more-effective and less-costly therapeutic options. © 2017 John Wiley & Sons A/S.

    Periodontal disease, which includes gingivitis and periodontitis, is highly prevalent in adults and disease severity increases with age. The relationship between periodontal disease and oral cancer has been examined for several decades, but there is increasing interest in the link between periodontal disease and overall cancer risk, with systemic inflammation serving as the main focus for biological plausibility. Numerous case-control studies have addressed the role of oral health in head and neck cancer, and several cohort studies have examined associations with other types of cancers over the past decade. For this review, we included studies that were identified from either 11 published reviews on this topic or an updated literature search on PubMed (between 2011 and July 2016). A total of 50 studies from 46 publications were included in this review. Meta-analyses were conducted on cohort and case-control studies separately when at least 4 studies could be included to determine summary estimates of the risk of cancer in relation to 1) periodontal disease or 2) tooth number (a surrogate marker of periodontal disease) with adjustment for smoking. Existing data provide support for a positive association between periodontal disease and risk of oral, lung, and pancreatic cancers; however, additional prospective studies are needed to better inform on the strength of these associations and to determine whether other cancers are associated with periodontal disease. Future studies should include sufficiently large sample sizes, improved measurements for periodontal disease, and thorough adjustment for smoking and other risk factors. © The Author 2017.

El objetivo de este estudio fue determinar, según género, los patrones de conglomeración de algunos factores de riesgo de comportamiento en personas de 18 a 29 años de dos áreas urbanas de Bogotá. Métodos: Mediante la utilización de una encuesta se determinaron en 1.465 adultos jóvenes los patrones de conglomeración en cuatro factores de riesgo de comportamiento: aconsumo de alcohol, b bajo consumo de frutas y verduras, c inactividad física en tiempo libre y d consumo de tabaco. La muestra poblacional tuvo un diseño probabilístico multietápico. Mediante modelos de regresión logística se identificaron las variables sociodemográficas asociadas a tener dos o más de los comportamientos mencionados. Resultados: 13,9% de los adultos jóvenes no tenía ningún factor de riesgo, 35,5% tenía uno, 32,9% dos y, 17,7% tres o cuatro. El consumo agudo de alcohol fue el factor de riesgo más frecuente en los patrones de conglomeración en hombres; en mujeres lo fue la inactividad física en tiempo libre. En las mujeres tener dos o más factores de riesgo de comportamiento estuvo asociado con estar separada o divorciada; en los hombres se asoció con haber trabajado como principal actividad realizada en los últimos 30 días. Conclusiones: Las combinaciones de los factores de riesgo de comportamiento estudiados y los factores asociados a su nivel de conglomeración presentaron patrones diferentes en hombres y en mujeres. Estos hallazgos enfatizan la necesidad de diseñar intervenciones que sean sensibles a las diferencias de género.

    Full Text Available En este artículo planteamos una aproximación crítica a la «cuestión animal» desde la perspectiva de la enfermedad. El problema de la «animalidad», en efecto, y de su relación con lo humano, constituye un problema clave en las experiencias modernas de «lo patológico». Es frecuente, ciertamente, que en un contexto de enfermedad grave o ante un proceso patológico agudo se produzca un efecto de acercamiento o de asimilación entre el sujeto enfermo y el animal. En la mayoría de los casos, dicha animalización está íntimamente relacionada con el discurso y la práctica médica. Sin embargo, creemos que «lo animal» está irrumpiendo también de otro modo en nuestras experiencias de enfermedad. Para entender esta irrupción, creemos que es adecuado volver a recurrir a la idea del «devenir animal» de Deleuze. Con esta herramienta, nos enfrentamos a un corpus de textos literarios recientes en los se aprecia un «devenir animal» del enfermo que contesta a los procesos de animalización ligados a la clínica. El «devenir animal» del enfermo se materializa específicamente, en estos casos, en relación con un particular «devenir animal de la lengua».

    Chronic systemic inflammation, a non traditional risk factor of cardiovascular diseases, is associated with increasing mortality in chronic kidney disease, especially peritoneal dialysis patients. Periodontitis is a potential treatable source of systemic inflammation in peritoneal dialysis patients. Clinical periodontal status was evaluated in 32 stable chronic peritoneal dialysis patients by plaque index and periodontal disease index. Hematologic, blood chemical, nutritional, and dialysis-related data as well as highly sensitive C-reactive protein were analyzed before and after periodontal treatment. At baseline, high sensitive C-reactive protein positively correlated with the clinical periodontal status (plaque index; r = 0.57, P periodontal disease index; r = 0.56, P periodontal therapy, clinical periodontal indexes were significantly lower and high sensitivity C-reactive protein significantly decreased from 2.93 to 2.21 mg/L. Moreover, blood urea nitrogen increased from 47.33 to 51.8 mg/dL, reflecting nutritional status improvement. Erythropoietin dosage requirement decreased from 8000 to 6000 units/week while hemoglobin level was stable. Periodontitis is an important source of chronic systemic inflammation in peritoneal dialysis patients. Treatment of periodontal diseases can improve systemic inflammation, nutritional status and erythropoietin responsiveness in peritoneal dialysis patients. © 2013 The Authors.

    Substantial ongoing research continues to explore the contribution of genetics and environment to the onset, extent and severity of periodontal disease(s). Existing evidence supports that periodontal disease appears to have an increased prevalence in family units with a member having aggressive periodontitis. We have been using the nonhuman primate as a model of periodontal disease for over 25 years with these species demonstrating naturally occurring periodontal disease that increases with age. This report details our findings from evaluation of periodontal disease in skulls from 97 animals (5-31 years of age) derived from the skeletons of the rhesus monkeys (Macaca mulatta) on Cayo Santiago. Periodontal disease was evaluated by determining the distance from the base of the alveolar bone defect to the cemento-enamel junction on 1st/2nd premolars and 1st/2nd molars from all four quadrants. The results demonstrated an increasing extent and severity of periodontitis with aging across the population of animals beyond only compensatory eruption. Importantly, irrespective of age, extensive heterogeneity in disease expression was observed among the animals. Linking these variations to multi-generational matriarchal family units supported familial susceptibility of periodontitis. As the current generations of animals that are descendants from these matrilines are alive, studies can be conducted to explore an array of underlying factors that could account for susceptibility or resistance to periodontal disease. © 2016 Wiley Periodicals, Inc.

    Full Text Available El objetivo de este trabajo fue validar herramientas para que escolares puedan vigilar sus viviendas. Se desarrollaron dos tipos de planillas, una sobre la presencia de factores de riesgos y otra para registrar la presencia de vinchucas en las viviendas. Estas planillas fueron puestas a prueba en campo por 100 escolares de escuelas de áreas endémicas de Argentina y validadas en campo por personal técnico. Los resultados obtenidos por los escolares sobre porcentajes de viviendas que presentan factores de riesgos y viviendas positivas fueron similares a los obtenidos por el personal técnico. La información recabada permitió a los docentes caracterizar las viviendas como "con mucho riesgo", "de riesgo" o "sin riesgo". Esta información sobre nivel de riesgo de las viviendas puede ser una importante ayuda para los agentes primarios de salud. Por lo tanto, se recomienda incluir estas estrategias educativas en los programas de control, en especial para la fase de vigilancia.

    The cytokine, interleukin (IL)-32, is a relatively new discovery. However, it is very powerful for stimulating tumor necrosis factor-alpha (TNF-α) under inflammatory conditions. The objective of this research was to explore fluctuations in the levels of TNF-α, IL-32 and IL-10, in both saliva and gingival crevicular fluid. The focus was on measurements taken before and after clinical treatment of chronic periodontitis. For the purposes of the study, a total of 27 patients with chronic periodontitis and 27 controls (periodontally healthy) were recruited. Important clinical periodontal criteria were established before and 4 wk after the start of the research. The chronic periodontitis group was given an initial form of periodontal care. Samples of saliva and gingival crevicular fluid were collected exactly 4 wk preceding and 4 wk following the care. The levels of IL-10, IL-32 and TNF-α present in saliva and gingival crevicular fluid were recorded via the use of an ELISA. At baseline, the levels of TNF-α and IL-32 in the gingival crevicular fluid and saliva were significantly higher among patients in the chronic periodontitis group than among patients in the control group (p chronic periodontitis group than the control group (p chronic periodontitis group when compared with the baseline readings. However, the levels of IL-10 were significantly higher (p periodontitis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The purpose of this study was to assess the effect of a novel chemically modified curcumin (CMC 2.24) on NF-κB and MAPK signaling and inflammatory cytokine production in two experimental models of periodontal disease in rats. Experimental model I: Periodontitis was induced by repeated injections of LPS into the gingiva (3×/week, 3 weeks); control rats received vehicle injections. CMC 2.24, or the vehicle, was administered by daily oral gavage for 4 weeks. Experimental model II: Diabetes was induced in adult male rats by streptozotocin injection; periodontal breakdown then results as a complication of uncontrolled hyperglycemia. Non-diabetic rats served as controls. CMC 2.24, or the vehicle, was administered by oral gavage daily for 3 weeks to the diabetics. Hemimaxillae and gingival tissues were harvested, and bone loss was assessed radiographically. Gingival tissues were pooled according to the experimental conditions and processed for the analysis of matrix metalloproteinases (MMPs) and bone-resorptive cytokines. Activation of p38 MAPK and NF-κB signaling pathways was assessed by western blot. Both LPS and diabetes induced an inflammatory process in the gingival tissues associated with excessive alveolar bone resorption and increased activation of p65 (NF-κB) and p38 MAPK. In both models, the administration of CMC 2.24 produced a marked reduction of inflammatory cytokines and MMPs in the gingival tissues, decreased bone loss, and decreased activation of p65 (NF-κB) and p38 MAPK. Inhibition of these cell signaling pathways by this novel tri-ketonic curcuminoid (natural curcumin is di-ketonic) may play a role in its therapeutic efficacy in locally and systemically associated periodontitis.

    Full Text Available   Background and Aims: Periodontitis does not affect on all patients by the same way. There are some risk factors in some people that make them more sensitive to progress of periodontitis. Smoking, uncontrolled diabetes, and special pathogens increase the risk of periodontitis. Other factors such as stress, depression and anxiety, are not crucial risk factors for periodontitis yet. Biologic explanation of this relation is that mental conditions and exposure to stressful situations can alter immune response. The aim of this study was to review the psychological factors of anxiety and depression associated with periodontitis.   Materials and Methods: For this review article, we have searched through internet by the following keywords; periodontal disease, anxiety, depression. We have tried to cover almost all dental– related sites and journals as well as Pubmed from 1990-2010.   Conclusion: Most published studies support a positive relationship between periodontitis and several psycho-social factors. Life style, stressful conditions, hormonal changes, nonchalance in oral hygiene, habits such as smoking are predisposing factors in periodontal diseases.

Existen múltiples estudios en la literatura médica internacional que confirman lo anterior (2- 4. Las investigaciones demuestran que el consumo frecuente de bebidas azucaradas se ha asociado con el riesgo de sufrir sobrepeso y obesidad, el desarrollo de síndrome metabólico, diabetes de tipo 2 y con la aparición de cardiopatías. Si bien la obesidad consiste en un proceso multicausal, requiere de un conjunto de medidas estratégicas como advertencias en las etiquetas, la limitación del tamaño de los envases o la restricción del uso de máquinas dispensadoras de bebidas azucaradas como gaseosas; y, teniendo en cuenta que el precio constituye uno de los principales factores influyentes en la elección de esos alimentos, se espera que el impuesto disminuya el consumo, particularmente entre las clases populares en las cuales el riesgo de adquirir las patologías mencionadas es mayor.

    Siguiendo esta línea, los nuevos impuestos a este consumo conforman una tendencia mundial que ha sido recomendada por la Organización Mundial de la Salud (OMS como medida clave para evitar la expansión de enfermedades no transmisibles.

    Although the relationship between diabetes and periodontitis is well established, the association between periodontitis and prediabetes has been investigated less extensively. Furthermore, there has been little research on the prevalence of periodontitis among individuals with prediabetes and diabetes as well as in the overall population using nationally representative data.Among 12,406 adults (≥19 years' old) who participated in the 2012-2013 Korea National Health and Nutrition Examination Survey, a total of 9977 subjects completed oral and laboratory examinations and were included in this analysis. Periodontitis was defined as a community periodontal index score of ≥ 3 according to the World Health Organization criteria. The fasting plasma glucose level was categorized into the following 5 groups: normal fasting glucose (NFG) 1 (fasting glucose (IFG) 1 (100-110  mg/dL), IFG 2 (111-125  mg/dL), and diabetes (≥126  mg/dL).Overall, the weighted prevalence of periodontitis among the Korean adult population was 24.8% (23.3-26.4%) (weight n = 8,455,952/34,086,014). The unadjusted weighted prevalences of periodontitis were 16.7%, 22.8%, 29.6%, 40.7%, and 46.7% in the NFG 1, NFG 2, IFG 1, IFG 2, and diabetes groups, respectively (P < 0.001). After adjusting for age, sex, smoking history, heavy alcohol drinking, college graduation, household income, waist circumference, serum triglyceride level, serum high-density lipoprotein cholesterol level, and the presence of hypertension, the adjusted weighted prevalence of periodontitis increased to 29.7% in the IFG 2 group (P = 0.045) and 32.5% in the diabetes group (P < 0.001), compared with the NFG 1 group (24%). The odds ratios for periodontitis with the above-mentioned variables as covariates were 1.42 (95% confidence interval [CI] 1.14-1.77, P = 0.002) in the diabetes group and 1.33 (95% CI 1.01-1.75, P = 0.044) in the IFG 2 group, respectively, compared with the NFG1 group.In conclusion, a

Esta creciente prevalencia supone implicaciones tanto para el riesgo de desarrollo de diabetes y enfermedades cardiovasculares como para el desarrollo de enfermedad renal crónica. Un elevado índice de masa corporal es uno de los factores de riesgo más importantes para el desarrollo de enfermedad renal crónica. En individuos afectados por la obesidad, tiene lugar una hiperfiltración compensatoria necesaria para alcanzar la alta demanda metabólica secundaria al aumento del peso corporal. El incremeno de la presión intraglomerular puede generar daño renal y elevar el riesgo de desarrollar enfermedad renal crónica a largo plazo. La incidencia de glomerulopatía asociada a obesidad se ha incrementado 10 veces en los últimos años. Así mismo se ha demostrado que la obesidad es un factor de riesgo para el desarrollo de nefrolitiasis y un número de neoplasias, incluyendo cáncer renal.

    Periodontitis is a highly prevalent infectious disease, characterized by destruction of the periodontium, and is the main cause of tooth loss. Periodontitis is initiated by periodontal pathogens, while other risk factors including smoking, stress, and systemic diseases aggravate its progression. Periodontitis affects many people worldwide, but the molecular mechanisms by which pathogens and risk factors destroy the periodontium are unclear. Programmed cell death (PCD), different from necrosis, is an active cell death mediated by a cascade of gene expression events and can be mainly classified into apoptosis, autophagy, necroptosis, and pyroptosis. Although PCD is involved in many inflammatory diseases, its correlation with periodontitis is unclear. After reviewing the relevant published articles, we found that apoptosis has indeed been reported to play a role in periodontitis. However, the role of autophagy in periodontitis needs further verification. Additionally, implication of necroptosis or pyroptosis in periodontitis remains unknown. Therefore, we recommend future studies, which will unravel the pivotal role of PCD in periodontitis, allowing us to prevent, diagnose, and treat the disease, as well as predict its outcomes. © 2016 John Wiley & Sons A/S.

    Increasing evidence suggests that maternal gingivitis and periodontitis may be a risk factor for preterm birth and other adverse pregnancy outcomes. To clarify the possible mechanisms behind the association between periodontal disease and preterm delivery, the authors reviewed studies of the effect of infection with periodontal pathogens in animal models on pregnancy outcomes including fetal growth, placental structural abnormalities and neonatal health. After the first report, in 1996, of a potential association between maternal periodontal disease and delivery of a preterm/low-birth-weight infant in humans, many case control and prospective studies were published. This review summarizes these, as well as early studies involving periodontal intervention to reduce risk. Although there are some conflicting findings and potential problems regarding uncontrolled underlying risk factors, most of the clinical studies indicate a positive correlation between periodontal disease and preterm birth. Recent studies also have shown that there are microbiologic and immunological findings that strongly support the association. The studies indicate that periodontal infection can lead to placental-fetal exposure and, when coupled with a fetal inflammatory response, can lead to preterm delivery. Data from animal studies raise the possibility that maternal periodontal infections also may have adverse long-term effects on the infant's development. Education for patients and health care providers regarding the biological plausibility of the association and the potential risks is indicated, but there is insufficient evidence at this time for health care policy recommendations to provide maternal periodontal treatments for the purpose of reducing the risk of adverse pregnancy outcomes.

    The purpose of this study was to identify factors promoting formation of the cemento-periodontal ligament junction. Regeneration of the cemento-periodontal ligament junction is an important factor in recovery of the connective tissue attachment to the cementum and it is important to identify all specific substances that promote its formation. To clarify the substances involved in cemento-periodontal ligament junction formation, we produced a monoclonal antibody (mAb) to human cemento-periodontal ligament junction (designated as the anti-TAP mAb) and examined its immunostaining properties and reactive antigen. Hybridomas producing monoclonal antibody against human cemento-periodontal ligament junction antigens were established by fusing P3U1 mouse myeloma cells with spleen cells from BALB/c mice immunized with homogenized human cemento-periodontal ligament junction. The mAb, the anti-TAP mAb for cemento-periodontal ligament junction, was then isolated. The immunoglobulin class and light chain of the mAb were examined using an isotyping kit. Before immunostaining, antigen determination using an enzymatic method or heating was conducted. Human teeth, hard tissue-forming lesions, and animal tissues were immunostained by the anti-TAP mAb. The anti-TAP mAb was positive in human cemento-periodontal ligament junction and predentin but negative in all other human and animal tissues examined. In the cemento-osseous lesions, the anti-TAP mAb was positive in the peripheral area of the cementum and cementum-like hard tissues and not in the bone and bone-like tissues. The anti-TAP mAb showed IgM (kappa) and recognized phosphoprotein. The anti-TAP mAb is potentially useful for developing new agents promoting cementogenesis and periodontal regeneration.

    Studies have supported the notion that subjects with periodontitis and patients with multiple tooth extractions as a result of chronic advanced periodontal disease (PDD) have a greater risk of developing Cardiovascular disease (CVD) than those who had little or no periodontal infection. Periodontitis may predispose affected patients to CVD by elevating systemic C-reactive protein level and pro-inflammatory activity in atherosclerotic lesions and accelerate development of cardiovascular diseases, Oral health variables including loss of teeth, positive plaque Benzoyl-D-L-Arginine- Naphthyl Amide test (BANA) scores, and compliant of xerostomia may by considered as risk indicators for CVD. Exact mechanism which links PDD and CVD has not been firmly established. The link between PDD and CVD may be attributed to bacteria entering blood stream and attaching to the fatty plaque in coronary artery and contributing to clot formation which can lead to heart attack. Inflammation caused by PDD increases the plaque build up. The association between the two disease entities is cause for concern. However, dental and medical practitioners should be aware of these findings to move intelligently to interact with inquiring patients with periodontitis. They should be urged to maintain medical surveillance of their cardiovascular status, and work on controlling or reducing all known risk factors associated with CVD, including periodontal infection.

    Full Text Available Background and Aim: Preeclampsia is a considerable problem of pregnancy. Endothelial dysfunction and placental hypoxia are the current hypothesis of preeclampsia. Chronic inflammation, including periodontitis may provoke systemic maternal and placental pro-inflammatory endothelial dysfunction, which represent a significant risk factor for diseases of vascular origin. So this study was carried out to evaluate the possible relationship between periodontitis and preeclampsia. Methods: A total of 360 pregnant women were included, corresponding to 180 pregnant women with mild or sever periodotitis in one group and 180 pregnant women with periodontal health in the other group. Periodontitis was determined by the sum of all pockets with pocket probing depth (PPD ≥4mm and bleeding on probing. periodontal health was defined as the absence of PPD≥ 4mm. Then two groups evaluated to determine the presence of preeclampsia. After delivery, Child weight at birth and gestational age was also evaluated. Chi square and t test analysis were used to analyze the data. Results: There was statistically significant difference between two groups in presence of preeclampsia (p=0.003. Women who had a worse periodontal condition were at higher risk for preeclampsia. In addition, birth weight and gestational age was statistically lower in the case group than the control group (p < 0.001. Conclusion: The results indicate that the presence and severity of peridontitis increase the risk for occurrence of preeclampsia and adverse pregnancy outcomes.

    Periodontal disease (periodontitis) is a chronic inflammatory condition initiated by microbial infection that leads to gingival tissue destruction and alveolar bone resorption. The periodontal tissue's response to dental plaque is characterized by the accumulation of polymorphonuclear leukocytes, macrophages, and lymphocytes, all of which release inflammatory mediators and cytokines to orchestrate the immunopathogenesis of periodontal disease. Ubiquitination is achieved by a mechanism that involves a number of factors, including an ubiquitin-activating enzyme, ubiquitin-conjugating enzyme, and ubiquitin-protein ligase. Ubiquitination is a post-translational modification restricted to eukaryotes that are involved in essential host processes. The ubiquitin system has been implicated in the immune response, development, and programmed cell death. Increasing numbers of recent reports have provided evidence that many approaches are delivering promising reports for discovering the relationship between ubiquitination and periodontal disease. The scope of this review was to investigate recent progress in the discovery of ubiquitinated protein in diseased periodontium and to discuss the ubiquitination process in periodontal diseases.

    Periodontitis is an inflammatory disease of gums involving the degeneration of periodontal ligaments, creation of periodontal pocket and resorption of alveolar bone, resulting in the disruption of the support structure of teeth. According to WHO, 10-15% of the global population suffers from severe periodontitis. The disease results from the growth of a diverse microflora (especially anaerobes) in the pockets and release of toxins, enzymes and stimulation of body's immune response. Various local or systemic approaches were used for an effective treatment of periodontitis. Currently, controlled local drug delivery approach is more favorable as compared to systemic approach because it mainly focuses on improving the therapeutic outcomes by achieving factors like site-specific delivery, low dose requirement, bypass of first-pass metabolism, reduction in gastrointestinal side effects and decrease in dosing frequency. Overall it provides a safe and effective mode of treatment, which enhances patient compliance. Complete eradication of the organisms from the sites was not achieved by using various surgical and mechanical treatments. So a number of polymer-based delivery systems like fibers, films, chips, strips, microparticles, nanoparticles and nanofibers made from a variety of natural and synthetic materials have been successfully tested to deliver a variety of drugs. These systems are biocompatible and biodegradable, completely fill the pockets, and have strong retention on the target site due to excellent mucoadhesion properties. The review summarizes various available and recently developing targeted delivery devices for the treatment of periodontitis.

    Studies have supported the notion that subjects with periodontitis and patients with multiple tooth extractions as a result of chronic advanced periodontal disease (PDD) have a greater risk of developing Cardiovascular disease (CVD) than those who had little or no periodontal infection. Periodontitis may predispose affected patients to CVD by elevating systemic C-reactive protein level and pro-inflammatory activity in atherosclerotic lesions and accelerate development of cardiovascular diseases, Oral health variables including loss of teeth, positive plaque Benzoyl-D-L-Arginine- Naphthyl Amide test (BANA) scores, and compliant of xerostomia may by considered as risk indicators for CVD. Exact mechanism which links PDD and CVD has not been firmly established. The link between PDD and CVD may be attributed to bacteria entering blood stream and attaching to the fatty plaque in coronary artery and contributing to clot formation which can lead to heart attack. Inflammation caused by PDD increases the plaque build up. The association between the two disease entities is cause for concern. However, dental and medical practitioners should be aware of these findings to move intelligently to interact with inquiring patients with periodontitis. They should be urged to maintain medical surveillance of their cardiovascular status, and work on controlling or reducing all known risk factors associated with CVD, including periodontal infection.

    Full Text Available Context Oral cavity is one of the most common sites for neoplasms with a multifactorial etiology. Tobacco and alcohol are the main risk factors. Periodontal disease is an inflammatory disease affecting periodontal tissues such as gingiva, periodontal ligament and alveolar bone. Periodontal disease is linked to many systemic diseases. Recently a link between periodontal disease and cancer is suggested. The current review article aimed to evaluate the association between periodontal disease and risk of cancer in the oral cavity and some related factors. Evidence Acquisition Evidence suggests that oral cavity cancer is significantly more prevalent in patients with periodontal disease, poor oral hygiene or more missing teeth. Clinically, gingival squamous cell carcinoma (GSCC usually appears as an exophytic mass with a granular, papillary or verrucous surface or presents as an ulcerative lesion. Some reported cases of GSCC mimicking periodontal disease include gingival enlargement with no bone invasion, dentoalveolar abscess, erosive erythematosus lesion with keratotic papules, root exposure and tooth mobility, verrucous leukoplakia, verruciform xanthoma and development of hyperplastic granulation tissue after tooth extraction. Greater burden of oral flora that produce carcinogenic metabolites, human papilloma virus (HPV and other viruses that are residents of periodontal pocket, increased amount of inflammatory mediators and markers and some periodontal pathogens affecting cell cycle leading to mutation and dysplasia are considered as the rational for the relationship between malignant lesions of oral cavity and periodontal disease. Results Cancer of the oral cavity and periodontal disease are related from different aspects. Periodontal disease and tooth loss are considered as independent risk factors for cancer. Gingival squamous cell carcinoma can also mimic periodontal disease leading to misdiagnosis and delayed commencement of appropriate

    Chronic periodontitis is multifactorial and numerous risk factors have been identified to contribute in the disease progression. Current study aimed to conduct a cross-sectional study in a population of patients with cardiovascular diseases in order to correlate the association between obesity [body mass index (BMI) and waist circumference (WC)] and periodontal disease parameters. The study was of a cross-sectional design and a total of 201 patients were examined after obtaining their informed consent. Subjects who had a history of cardiovascular diseases and under treatment were included in the study. Two indicators of obesity were used: BMI and WC. The following periodontal parameters were assessed: Probing depth, clinical attachment level. The oral hygiene status of the subjects was assessed by the oral hygiene index (OHI, simplified) given by John C Greene and Jack R Vermillion. The influence of the BMI and other confounding variables on periodontitis severity was assessed by multivariate logistic regression analysis. Data were analyzed using SPSS. Significant association was seen with low density lipoproteins (LDL) and severity of periodontitis (p < 0.005), triglyceride levels (TGL) and severity of periodontitis (p < 0.005), cholesterol and severity of periodontitis (p < 0.005), BMI and severity of periodontitis (p < 0.001), OHI and severity of periodontitis (p < 0.001). Significant association was seen with smoking and severity of periodontitis (p < 0.005), BMI and severity of periodontitis (p < 0.001), WC and severity of periodontitis (p < 0.001), cholesterol and severity of periodontitis (p < 0.001), OHI and severity of periodontitis (p < 0.001). Obesity has been implicated as a risk factor for several conditions including cardiovascular disease, diabetes, etc. In our study the relation between measures of overall and abdominal obesity (BMI and WC) and periodontal disease showed significant association in the multivariate logistic regression analysis

    Full Text Available Background: Periodontal disease, commonly known as periodontitis is an infectious disease which has multifactorial etiologic factors. It may affect everybody in any ages with no gender nor sex predilection and usually can be detected under routine clinical examination. This disease is a manifestation of local factors, host factor and environmental factors, resulting in periodontal tissue damage which may cause tooth mobility and tooth loss. Interleukin-1 is a pro-inflammatory protein which functions primarily as inflammatory mediator in host innate immune responses. IL-1 is a regulator, affecting many biological activities including proliferation, development, homeostasis, regeneration, repair and inflammation which contribute to tissue damage and alveolar bone resorption. Purpose: This research was aimed to reveal the basic pathogenesis of periodontitis and could determine the future definitive treatment for patients with periodontitis. Methods: Data were obtained from 40 patients with aggressive periodontitis and 40 patients with chronic periodontitis. Samples were collected from periodontal tissue patients and protein expression of IL-1β was performed with immunohistochemistry. Results: Most female patient suffer aggressive periodontitis and chronic periodontitis. The datas were analyzed with t-test. The t values result was -8623, significance 0.001, with α = 5%, which indicated there was significant difference in IL-1β expression between aggressive and chronic periodontitis. The box plot diagram showed marked difference in distribution of protein expression of IL-1β between patients with aggressive periodontitis and chronic periodontitis. With a regression equation, it might be concluded that the protein expression of IL-1β might affect the incidence of aggressive periodontitis and chronic periodontitis. The OR value was calculated for 0.746 (sign.= 0.001, which indicate each increment of one unit protein expression of IL-1β will lead

    We have discussed the essential property for periodontal disease medication using protein, such as recombinant human basic fibroblast growth factor (rhbFGF). In our previous study, the criteria of thickener for the medication, viscosity, flowability etc., were set. The aim of this study was to evaluate the physical and chemical effect of concomitant use of general dental drug or device on thickener properties for the clinical use of viscous rhbFGF formulation. Viscous formulation was prepared with six cellulose derivatives, two types hydroxy propyl cellulose (HPC), three types hydroxy ethyl cellulose (HEC) and methyl cellulose (MC). Antibiotic ointment, local anesthetic, bone graft substitute, agent for gargle and mouthwashes, were chosen as general dental drug and device. These drugs and device were mixed with the viscous formulations and the change of viscosity and flowability, the remaining ratio of rhbFGF were evaluated. When the various thickener solutions were mixed with the liquid drugs, viscosity and flowability did not changed much. However, in the case of MC solution, viscous property declined greatly when MC solution was mixed with cationic surfactant for gargle. The flowabilities of thickener solutions were declined with insoluble bone graft. The stabilities of rhbFGF in thickener solutions were no problem for 24 hours even in the case of mixing with dental drug or device. Our findings suggested that the viscous rhbFGF formulations prepared in this research were not substantially affected by the concomitant use of dental drug or device, especially the formulation with HPC or HEC was useful.

    There is a deep relationship between cardiovascular disease and periodontitis. It has been reported that myocardial hypertrophy may be affected by periodontitis in clinical settings. Although these clinical observations had some study limitations, they strongly suggest a direct association between severity of periodontitis and left ventricular hypertrophy. However, the detailed mechanisms between myocardial hypertrophy and periodontitis have not yet been elucidated. Recently, we demonstrated that periodontal bacteria infection is closely related to myocardial hypertrophy. In murine transverse aortic constriction models, a periodontal pathogen, Aggregatibacter actinomycetemcomitans markedly enhanced cardiac hypertrophy with matrix metalloproteinase-2 activation, while another pathogen Porphyromonas gingivalis (P.g.) did not accelerate these pathological changes. In the isoproterenol-induced myocardial hypertrophy model, P.g. induced myocardial hypertrophy through Toll-like receptor-2 signaling. From our results and other reports, regulation of chronic inflammation induced by periodontitis may have a key role in the treatment of myocardial hypertrophy. In this article, we review the pathophysiological mechanism between myocardial hypertrophy and periodontitis.

    Periodontal diseases are among the most prevalent oral diseases in the world. Apart from repercussions in the oral cavity, there is evidence that periodontitis contributes to systemic damage in chronic diseases such as cardiovascular disease, diabetes, and preterm low birth weight. The aims of this study were to estimate the prevalence of chronic periodontitis in a sample urban population (<18 years) in Tamil Nadu and to estimate the inflammatory burden posed by chronic periodontitis by calculating the periodontal inflammatory surface area. This was a population-based study and cross-sectional design. A total of 1000 individuals (<18 years) were selected and screened for their periodontal status, oral hygiene status (OHI), and the periodontal inflamed surface area (PISA) in an outreach center located in Chennai, India. The proportion of individuals with different periodontal states (health, gingivitis, and periodontitis) was determined. A multivariate logistic regression analysis was performed to assess the influence of the individual risk factors such as habits (tobacco use), systemic conditions (diabetes), and oral hygiene maintenance on periodontitis prevalence in the sample population. A high prevalence of periodontal disease was observed in the study population (42.3%). Among the urban participants, age, cigarette smoking, pan chewing, decayed, missing, and filled teeth scores, OHI scores, and PISA scores were found to be significantly associated with periodontitis (P < 0.05). Periodontitis prevalence appears to be high even in areas with adequate access to oral health care and an inflammatory burden risk exists in a definitive manner.

    Full Text Available Intermittent hypoxia (IH recapitulates morphological changes in the maxillofacial bones in children with obstructive sleep apnea (OSA. Recently, we found that IH increased bone mineral density (BMD in the inter-radicular alveolar bone (reflecting enhanced osteogenesis in the mandibular first molar (M1 region in the growing rats, but the underlying mechanism remains unknown. In this study, we focused on the hypoxia-inducible factor (HIF pathway to assess the effect of IH by testing the null hypothesis of no significant differences in the mRNA-expression levels of relevant factors associated with the HIF pathway, between control rats and growing rats with IH. To test the null hypothesis, we investigated how IH enhances mandibular osteogenesis in the alveolar bone proper with respect to HIF-1α and vascular endothelial growth factor (VEGF in periodontal ligament (PDL tissues. Seven-week-old male Sprague–Dawley rats were exposed to IH for 3 weeks. The microstructure and BMD in the alveolar bone proper of the distal root of the mandibular M1 were evaluated using micro-computed tomography (micro-CT. Expression of HIF-1α and VEGF mRNA in PDL tissues were measured, whereas osteogenesis was evaluated by measuring mRNA levels for alkaline phosphatase (ALP and bone morphogenetic protein-2 (BMP-2. The null hypothesis was rejected: we found an increase in the expression of all of these markers after IH exposure. The results provided the first indication that IH enhanced osteogenesis of the mandibular M1 region in association with PDL angiogenesis during growth via HIF-1α in an animal model.

    Full Text Available Aggressive periodontitis is a periodontal disease occurring in healthy adolescent which is characterized by rapid loss alveolar bone happened in more than one permanent tooth.This disease has been classified in two types: localized and generalized. Localized aggressive periodontitis is characteristized by bone loss around the first molar and incisal, while generalized aggressive periodontitis is characterized by bone widespread pattern of periodontal distraction. One of the clinical feature aggressive periodonitis is distolabial migration of the maxillary incisors with concomitant diastema  formation. Radiographic findings show alveolar bone loss extending from the distal surface of the second premolar to the mesial surface of the second molar. Diabetes mellitus (DM is one of the predisposition factors that cause infection. DM will increase quantity of bacteria in oral, which will cause destruction in periodontal tissue, and continue to cause tooth mobility. However, well controlled DM patients can decrease the infection. The purpose of this study is to to inform a case with aggressive periodontitis with diabetes mellitus. A male 36 old presented with chief complaint mobile teeth and esthetic problem teeth. Radiographic evidence of severe attachment loss and bone loss around almost all the teeth. Treatment consisted of consulted to internist to control blood glucose level, periodontal pocket treatment with scalling root planing, splinting, flap surgery and antibiotic administration. The patient’s periodontal condition was stablized post treatment. Controlling oral hygiene to preventive disease progression was scheduled every three months. Patient refered to ortodontist to get ortodontic treatment to get esthetic result.

    Pre-term birth is a major cause of infant mortality and morbidity that has considerable societal, medical, and economic costs. The rate of pre-term birth appears to be increasing world-wide and efforts to prevent or reduce its prevalence have been largely unsuccessful. To review the literature for studies investigating periodontal disease as a possible risk factor for pre-term birth and adverse pregnancy outcomes. Variability among studies in definitions of periodontal disease and adverse pregnancy outcomes as well as widespread inadequate control for confounding factors and possible effect modification make it difficult to base meaningful conclusions on published data. However, while there are indications of an association between periodontal disease and increased risk of adverse pregnancy outcome in some populations, there is no conclusive evidence that treating periodontal disease improves birth outcome. Based on a critical qualitative review, available evidence from clinical trials indicates that, although non-surgical mechanical periodontal treatment in the second trimester of pregnancy is safe and effective in reducing signs of maternal periodontal disease, it does not reduce the rate of pre-term birth. Clinical trials currently underway will further clarify the potential role of periodontal therapy in preventing adverse birth outcomes. Regardless of the outcomes of these trials, it is recommended that large, prospective cohort studies be conducted to assess risk for adverse pregnancy outcome in populations with periodontal disease. It is critical that periodontal exposure and adverse birth outcomes be clearly defined and the many potential confounding factors and possible effect modifiers for adverse pregnancy outcome be controlled in these studies. If periodontal disease is associated with higher risk of adverse pregnancy outcome in these specific populations, large multicenter randomized-controlled trials will be needed to determine if prevention or

    Background Periodontitis has been regarded as a potential risk factor for rheumatoid arthritis (RA). A systematic review is made to determine whether nonsurgical periodontal treatment in patients with RA offers benefits in terms of the clinical activity and inflammatory markers of the disease. Material and Methods A search was made of the Medline-PubMed, Cochrane, Embase and Scopus databases to identify studies on the relationship between the two disease processes, and especially on the effects of nonsurgical treatment in patients of this kind. The search was based on the following keywords: rheumatoid arthritis AND periodontitis (MeSH), rheumatoid arthritis AND periodontal treatment. Results Eight articles on the nonsurgical treatment of patients with periodontitis and RA were finally included in the study. All of them evaluated clinical (DAS28) and laboratory test activity (ESR, CRP, IL-6, TNFα) before and after treatment. A clear decrease in DAS28 score and ESR was recorded, while other parameters such as CRP, IL-6 and TNFα showed a non significant tendency to decrease as a result of treatment. Conclusions Nonsurgical treatment improved the periodontal condition of patients with periodontitis and RA, with beneficial effects upon the clinical and laboratory test parameters (DAS28 and ESR), while other inflammatory markers showed a marked tendency to decrease. However, all the studies included in the review involved small samples sizes and follow-up periods of no more than 6 months. Larger and particularly longitudinal studies are therefore needed to more firmly establish possible significant relations between the two disease processes.

    We report a case involving a 12-year follow-up after treatment for chronic periodontitis with furcation involvement. A 54-year-old woman presented with the chief complaint of hypersensitivity. Clinical examination at the first visit revealed 15% of sites with a probing depth ≥4 mm and 35% of sites with bleeding on probing. Initial periodontal therapy was implemented based on a clinical diagnosis of severe chronic periodontitis. Surgical periodontal therapy was subsequently performed at selected sites. For #44, regenerative periodontal therapy using enamel matrix derivative (Emdogain(®)) was selected. For #16, which exhibited a 2- to 3-wall vertical bony defect and class III (mesio-distal) furcation involvement, bone graft was scheduled. Other sites with residual periodontal pockets were treated by open flap debridement. For #37, with a gutter-shaped root, odontoplasty was performed. After reevaluation, the patient was placed on supportive periodontal therapy (SPT). During 12 years of SPT, the periodontal condition remained uneventful in most of the teeth. However, bone resorption was observed in the distal aspect of #37, making the prognosis poor. This indicates the need to continuously monitor risk factors, including inflammation and traumatic occlusion, during SPT. Although some problems still remain, severe periodontitis with furcation involvement was successfully maintained longitudinally with an adequate level of patient compliance and careful SPT.

    Full Text Available Periodontal disease is a multifactorial disease having various risk factors, but a dynamic interaction between bacterial products and host response in association with genetic and environmental factors is considered as the primary cause for periodontal tissue destruction in periodontitis. This bacterial-host interaction which is ever-so-present in periodontitis directs us toward utilizing antimicrobial agents along with the routine mechanical debridement. This case report present a case of a female patient with recurrent periodontal infections with gingival enlargement treated with systemic Minocycline in conjunction with the conventional non-surgical approach.

    A number of systemic disorders increase patient susceptibility to periodontal disease, which moreover evolves more rapidly and more aggressively. The underlying factors are mainly related to alterations in immune, endocrine and connective tissue status. These alterations are associated with different pathologies and syndromes that generate periodontal disease either as a primary manifestation or by aggravating a pre-existing condition attributable to local factors. This is where the role of bacterial plaque is subject to debate. In the presence of qualitative or quantitative cellular immune alterations, periodontal disease may manifest early on a severe localized or generalized basis--in some cases related to the presence of plaque and/or specific bacteria (severe congenital neutropenia or infantile genetic agranulocytosis, Chediak-Higiashi syndrome, Down syndrome and Papillon-Lefévre syndrome). In the presence of humoral immune alterations, periodontal damage may result indirectly as a consequence of alterations in other systems. In connective tissue disorders, bacterial plaque and alterations of the periodontal tissues increase patient susceptibility to gingival inflammation and alveolar resorption (Marfan syndrome and Ehler-Danlos syndrome). The management of periodontal disease focuses on the control of infection and bacterial plaque by means of mechanical and chemical methods. Periodontal surgery and even extraction of the most seriously affected teeth have also been suggested. There are variable degrees of consensus regarding the background systemic disorder, as in the case of Chediak-Higiashi syndrome, where antibiotic treatment proves ineffective; in severe congenital neutropenia or infantile genetic agranulocytosis, where antibiotic prophylaxis is suggested; and in Papillon-Lefévre syndrome, where an established treatment protocol is available.

    Coffee is a major dietary source of antioxidants as well as of other anti-inflammatory factors. Given the beneficial role of such factors in periodontal disease, whether coffee intake is associated with periodontal disease in adult males was explored. Existing data collected by a prospective, closed-panel cohort study of aging and oral health in adult males was used. Participants included the 1,152 dentate males in the Veterans Affairs (VA) Dental Longitudinal Study who presented for comprehensive medical and dental examinations from 1968 to 1998. Mean age at baseline was 48 years; males were followed for up to 30 years. Participants are not VA patients; rather, they receive their medical and dental care in the private sector. Periodontal status was assessed by probing depth (PD), bleeding on probing, and radiographic alveolar bone loss (ABL), measured on intraoral periapical radiographs with a modified Schei ruler method. Moderate-to-severe periodontal disease was defined as cumulative numbers of teeth exhibiting PD ≥4 mm or ABL ≥40%. Coffee intake was obtained from participant self-reports using the Cornell Medical Index and food frequency questionnaires. Multivariate repeated-measures generalized linear models estimated mean number of teeth with moderate-to-severe disease at each examination by coffee intake level. It was found that higher coffee consumption was associated with a small but significant reduction in number of teeth with periodontal bone loss. No evidence was found that coffee consumption was harmful to periodontal health. Coffee consumption may be protective against periodontal bone loss in adult males.

    The aim of our study was to assess the subgingival profile of 9 periodontal pathogens, by means of real-time PCR, in a group of predialysis chronic kidney disease patients with and without periodontal disease and to identify the risk factors associated with periodontal disease in these patients. This is a single centre cross-sectional cohort study performed on 70 CKD patients. Patients received a full-mouth periodontal examination and the following parameters were assessed: periodontal pocket depth (PPD), clinical attachment level, bleeding on probing, and plaque index; subgingival biofilm samples were collected from the deepest periodontal pocket of each quadrant and were pooled in one transporting unit. Clinical data were drawn from the medical file of the patients. T. denticola (P = 0.001), T. forsythia (P < 0.001), and P. micros (P = 0.003) are significantly associated with periodontal disease in CKD subjects but in a multivariate model only age and T. forsythia remain independent risk factors for periodontal disease in patients with CKD. In our cohort, age and T. forsythia are independently associated with periodontitis in CKD patients. Within the limits of this study, CKD was not significantly associated with a particular subgingival periodontal pathogens profile in periodontitis patients.

    Full Text Available The research goal is to study clinical and immunological features of parodentium and cytokine profile in oral cavity of pregnant women. The condition of parodentium tissues was studied at 200 women with physiological pregnancy and 300 women with pregnancy complicated by gestosis. According to the results of examination 50 women with gestosis and 50 women with physiological pregnancy had inflammatory periodontal diseases. Phenotyping of lymphocytes by immunofluorescence method, investigation of necrosis containing factor of tumour-a, interleukin-8, interleukin-4 and transforming growth factor beta-1 in oral cavity by immunofermental analysis were performed. Frequency and character of inflammatory periodontal diseases at pregnancy were defined. Correlation of gingivitis and periodontitis at pregnancy with extragenital pathology was demonstrated. Immune and cytokine disbalance contributed greatly to pathogenesis of inflammatory periodontal diseases at pregnant women. Thus pathogenesis of oral hygiene, smoking, gestosis, immunosuppression and cytokine disbalance affects inflammatory periodontal diseases at pregnant women

    The aim of the present study was to clarify whether there is any correlation between the levels of high-sensitivity C reactive protein (hs-CRP) and stem cell factor (SCF) in serum and gingival crevicular fluid (GCF) of patients with chronic periodontitis (CP) with and without type 2 diabetes mellitus (DM). A total of 40 subjects were divided into 3 groups: 10 periodontally healthy subjects (Group 1), 15 CP patients (Group 2), and 15 type 2 DM patients with CP (Group 3). Levels of hs-CRP and SCF in GCF and serum were quantified using different techniques. The clinical outcomes evaluated were gingival index (GI), probing depth (PD) and clinical attachment level (CAL), and the correlations of the two inflammatory mediators with clinical parameters were evaluated. The levels of these inflammatory mediators increased continuously from group 1 to group 2, and to group 3. The serum levels of both hs-CRP and SCF were correlated with PD in patients with CP (P periodontal disease, and elsewhere.

    Full Text Available La caries dental es una de las enfermedades más comunes en la infancia y las personas continúan siendo susceptible a través de la vida. Aunque actualmente puede ser detenida y potencialmente revertida en etapas tempranas, no es autolimitada, progresa en forma crónica si no existe un cuidado y control de los factores que la producen, llegando a la destrucción de dientes, dolor, alteraciones funcionales, sistémicas y consecuencias en la calidad de vida de las personas. La caries temprana de infancia, de inicio precoz en niños, es causada en forma frecuente por hábitos alimenticios inapropiados y la adquisición temprana de microorganismos como Streptococcus mutans. Se ha sugerido una transmisión vertical de madre a hijo como la vía principal de adquisición de Streptococcus mutans, y también se ha demostrado en la literatura, que existiría una transmisión horizontal entre niños y sus cuidadores, compañeros de jardín infantil y colegios. Por esta razón durante muchos años se ha definido la enfermedad caries como infecciosa y transmisible. Nuevos avances en técnicas moleculares han dado evidencia acerca de la microflora autóctona y cómo la placa dental o biofilm funciona como un sistema ecológico dinámico y complejo. Existe evidencia que la caries dental no es una enfermedad infecciosa clásica, como se creía hace unos años, por el contrario, esta enfermedad es el resultado de un cambio ecológico en la biopelícula adquirida en la superficie dental. Además la transmisión de Streptococcus mutans de la madre hacia el hijo no implica que la enfermedad se desarrolle, por el contrario, la caries dental hoy se describe como una enfermedad común, compleja y multifactorial, donde interactúan varios factores de riesgo, entre los más destacados conductuales, ambientales y genéticos.

    In the clinical dentists and periodontal researchers' community, there is an obvious demand for a systems model capable of linking the clinical presentation of periodontitis to underlying molecular knowledge. A computer-readable representation of processes on disease development will give periodontal researchers opportunities to elucidate pathways and mechanisms of periodontitis. An ontology for periodontitis can be a model for integration of large variety of factors relating to a complex disease such as chronic inflammation in different organs accompanied by bone remodeling and immune system disorders, which has recently been referred to as osteoimmunology. Terms characteristic of descriptions related to the onset and progression of periodontitis were manually extracted from 194 review articles and PubMed abstracts by experts in periodontology. We specified all the relations between the extracted terms and constructed them into an ontology for periodontitis. We also investigated matching between classes of our ontology and that of Gene Ontology Biological Process. We developed an ontology for periodontitis called Periodontitis-Ontology (PeriO). The pathological progression of periodontitis is caused by complex, multi-factor interrelationships. PeriO consists of all the required concepts to represent the pathological progression and clinical treatment of periodontitis. The pathological processes were formalized with reference to Basic Formal Ontology and Relation Ontology, which accounts for participants in the processes realized by biological objects such as molecules and cells. We investigated the peculiarity of biological processes observed in pathological progression and medical treatments for the disease in comparison with Gene Ontology Biological Process (GO-BP) annotations. The results indicated that peculiarities of Perio existed in 1) granularity and context dependency of both the conceptualizations, and 2) causality intrinsic to the pathological processes

    Full Text Available Background. Periodontitis is the most common chronic inflammatory condition worldwide and is associated with incident coronary disease. Hypothesis. We hypothesized that periodontal disease would also be associated with cardiac calcification, a condition which shares many risk factors with atherosclerosis and is considered a marker of subclinical atherosclerosis. Methods. Cross-sectional study at two sites (USA and Japan involving subjects with both clinical echocardiograms and detailed dental examinations. Semiquantitative scoring systems were used to assess severity of periodontal disease and echocardiographic calcification. Results. Fifty-six of 73 subjects (77% had cardiac calcifications, and 51% had moderate to severe periodontal disease (score > 2. In unadjusted analysis, a significant relationship between periodontal score and cardiac calcification (Spearman rho = 0.4, P=0.001 was noted, with increases in mean calcification score seen across increasing levels of periodontal disease. On multivariate logistic regression, adjusted for age, gender, race, glomerular filtration rate, and traditional risk factors, this association remained significant (P=0.024. There was no significant interaction by study site, race, or gender. Conclusions. In a multiracial population, we found a significant association between the degree of periodontal disease, a chronic inflammatory condition, and cardiac calcification. Further, higher periodontal scores were associated with greater degrees of calcification.

    In the course of life the periodontum is subject to changes which may be physiological or pathological. Intraoral radiographs give insight into the hard structures of the dentomaxillar region and provides information on lesions in the bone of the periodontum in that they show radiopacities and radiolucencies caused by such lesions. In this thesis the relation is investigated between the true shape and dimensions of periodontal bone lesions and their radiographic images. A method is developed and tested of making standardized and reproducible radiographs suitable for longitudinal studies of periodontal lesions. Also the possibility is demonstrated of an objective and reproducible interpretation of radiographic characteristics of periodontal bone lesions. (Auth.)

    The aim was to compare the detection frequency of periodontopathogens by using the Pado Test 4.5 and checkerboard DNA-DNA hybridization technique in chronic periodontitis patients. Thirty patients with chronic periodontitis were tested cross-sectionally with DNA/RNA oligogenomic probe method (IAI Pado Test 4.5) and DNA/DNA whole genomic probe (checkerboard) method. Samples were taken by two paper points at the deepest site in each of the four quadrants and pooled into one sample for each of the two methods. The samples were sent to the two laboratories (IAI, Zuchwil, Switzerland, and Oral Microbiology Laboratory, University of Gothenburg, Sweden) and were analyzed in a routine setting for the presence and amount of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia and Treponema denticola. While Pado Test 4.5 detected the four periodontal pathogens in 11 (36.7%) of the patients, the checkerboard method showed presence in all patients (100%) using the lower score (Score 1 corresponding to 104 bacterial cells) and 16 (53.3%) using a higher treshold (score 3 corresponding to between >105 and 106 cells). The results of the present study showed low agreement for a positive microbiological outcome using the two diagnostic methods. It was also concluded that microbiological analysis in practice should include a larger number of bacterial species to better serve as markers for a diseased associated flora in chronic periodontitis cases.

  18. Aggressive periodontitis: case definition and diagnostic criteria.

    Albandar, Jasim M

    2014-06-01

    Aggressive periodontitis is a destructive disease characterized by the following: the involvement of multiple teeth with a distinctive pattern of periodontal tissue loss; a high rate of disease progression; an early age of onset; and the absence of systemic diseases. In some patients periodontal tissue loss may commence before puberty, whereas in most patients the age of onset is during or somewhat after the circumpubertal period. Besides infection with specific microorganisms, a host predisposition seems to play a key role in the pathogenesis of aggressive periodontitis, as evidenced by the familial aggregation of the disease. In this article we review the historical background of the diagnostic criteria of aggressive periodontitis, present a contemporary case definition and describe the clinical parameters of the disease. At present, the diagnosis of aggressive periodontitis is achieved using case history, clinical examination and radiographic evaluation. The data gathered using these methods are prone to relatively high measurement errors. Besides, this diagnostic approach measures past disease history and may not reliably measure existing disease activity or accurately predict future tissue loss. A diagnosis is often made years after the onset of the disease, partly because current assessment methods detect established disease more readily and reliably than they detect incipient or initial lesions where the tissue loss is minimal and usually below the detection threshold of present examination methods. Future advancements in understanding the pathogenesis of this disease may contribute to an earlier diagnosis. Insofar, future case definitions may involve the identification of key etiologic and risk factors, combined with high-precision methodologies that enable the early detection of initial lesions. This may significantly enhance the predictive value of these tests and detect cases of aggressive periodontitis before significant tissue loss develops. © 2014

    Full Text Available Abstract Background Porphyromonas gingivalis is the foremost oral pathogen of adult periodontitis in humans. However, the mechanisms of bacterial invasion and the resultant destruction of the gingival tissue remain largely undefined. Results We report host-P. gingivalis interactions in primary human gingival fibroblast (HGF cells. Quantitative immunostaining revealed the need for a high multiplicity of infection for optimal infection. Early in infection (2–12 h, P. gingivalis activated the proinflammatory transcription factor NF-kappa B, partly via the PI3 kinase/AKT pathway. This was accompanied by the induction of cellular anti-apoptotic genes, including Bfl-1, Boo, Bcl-XL, Bcl2, Mcl-1, Bcl-w and Survivin. Late in infection (24–36 h the anti-apoptotic genes largely shut down and the pro-apoptotic genes, including Nip3, Hrk, Bak, Bik, Bok, Bax, Bad, Bim and Moap-1, were activated. Apoptosis was characterized by nuclear DNA degradation and activation of caspases-3, -6, -7 and -9 via the intrinsic mitochondrial pathway. Use of inhibitors revealed an anti-apoptotic function of NF-kappa B and PI3 kinase in P. gingivalis-infected HGF cells. Use of a triple protease mutant P. gingivalis lacking three major gingipains (rgpA rgpB kgp suggested a role of some or all these proteases in myriad aspects of bacteria-gingival interaction. Conclusion The pathology of the gingival fibroblast in P. gingivalis infection is affected by a temporal shift from cellular survival response to apoptosis, regulated by a number of anti- and pro-apoptotic molecules. The gingipain group of proteases affects bacteria-host interactions and may directly promote apoptosis by intracellular proteolytic activation of caspase-3.

    Metabolic syndrome (MetS) is a common chronic condition that increases the cardiovascular disease risk and is also linked to periodontitis. The study aim was to determine if a relationship exists between MetS and chronic periodontitis in adult Colombians. Participants were 220 healthy-gingivitis subjects and 431 periodontitis patients coming from the three largest Colombian cities. Periodontal status and MetS were determined in subjects. Univariate analysis and odds ratio were calculated within the 95 % confidence intervals and chi 2 test compared the groups. Variables were compared among the clinical periodontal groups and MetS by Wilcoxon and multivariate analysis, and logistic regression was performed for MetS and periodontitis. MetS had higher prevalence in periodontitis group (6.3 %) versus controls (3.2 %). In multivariate analysis, periodontitis was associated with MetS (adjusted OR = 2.72, 95 % CI 1.09-6.79), glucose intolerance with another component of MetS (adjusted OR = 1.78, 1.16 to 2.72), glucose resistance (adjusted OR = 11.46, 95 % CI 1.41-92.88), smoking (OR = 1.72, 95 % CI 1.09-2.71), and city of origin (2.69, 95 % CI 1.79-4.04). The study confirmed the positive association between MetS and periodontitis, being glucose sensitivity the strongly associated component. MetS must be taken into account by the dentist when evaluating risk factors for periodontitis, being useful for dentists to evaluate glycemia, lipidic profile, central obesity, and high blood pressure in patients. Interdisciplinary treatment must be recommended when a patient with MetS and periodontitis is being treated.

    To examine the prevalence and impact of gingivitis and periodontitis in patients having heart valve surgical procedures. Nationwide Inpatient Sample for the years 2004-2010 was used. All patients who had heart valve surgical procedures were selected. Prevalence of gingivitis/periodontitis was examined in these patients. Impact of gingivitis/periodontitis on hospital charges, length of stay, and infectious complications was examined. 596,190 patients had heart valve surgical procedures. Gingivitis/periodontitis was present in 0.2 percent. Outcomes included: median hospital charges ($175,418 with gingivitis/ periodontitis versus $149,353 without gingivitis/periodontitis) and median length of stay (14 days with gingivitis/periodontitis versus 8 days without gingivitis/periodontitis). After adjusting for the effects of patient- and hospital-level confounding factors, hospital charges and length of stay were significantly higher (p gingivitis/periodontitis compared to their counterparts. Further, patients with gingivitis/periodontitis had significantly higher odds for having bacterial infections (OR = 3.41, 95% CI = 2.33-4.98, p gingivitis/periodontitis. Presence of gingivitis and periodontitis is associated with higher risk for bacterial infections and significant hospital resource utilization.

    In this study, we aimed to investigate the efficacy of combined orthodontic-periodontic treatment in the treatment of patients with periodontitis and its effects on the levels of inflammatory cytokines. A total of 117 patients with periodontitis were randomly assigned to the basic group (receiving basic periodontic treatment, n = 58) and the combined group (receiving combined orthodontic-periodontic treatment, n = 59). In addition, 52 healthy people without periodontal disease were selected as the normal group. Probing depth, tooth mobility, plaque index, clinical attachment level, and sulcus bleeding index were recorded. ELISA was applied to detect gingival crevicular fluid (GCF) and serum levels of inflammatory cytokines. A 2-year clinical follow-up was conducted. Before treatment, the periodontal parameters (probing depth, tooth mobility, plaque index, clinical attachement level, and sulcus bleeding index) and GCF and serum levels of inflammatory cytokines (high-sensitivity C-reactive protein, interleukin-1β, interleukin-5, interleukin-6, interleukin-8, tumor necrosis factor-α, and prostaglandin E2) in the combined and basic groups were higher than those in the normal group. After 6 and 18 months of treatment, the periodontal parameters and GCF and serum levels of inflammatory cytokines decreased in the combined and basic groups. The periodontal parameters and the GCF and serum levels of inflammatory cytokines in the combined group were significantly lower than those in the basic group after 18 months of treatment. The combined group had a lower recurrence rate compared with the basic group. Combined orthodontic-periodontic treatment had good clinical efficacy in the treatment of periodontitis and could effectively decrease the levels of inflammatory cytokines.

    Periodontitis could be categorized as mild, moderate, and severe according to the severity of the disease. This categorizing system could also be used together with other classification systems. The present article introduced the status about the case definition of severe periodontitis, including the standard of case definitions for surveillance of periodontitis reported by the Centers for Disease Control and Prevention (CDC) in partnership with the American Academy of Periodontology (AAP) and the consensus report on the definition of periodontitis case for use in risk factor research by Europe workshop. A consensus on the state of the art definition of severe periodontitis for use in clinical work was gained base on the expertise of Chinese Society of Periodontology, Chinese Association of Stomatology. The background of this consensus and the significance of the criteria for the case definition were discussed.

    The periodontal status and treatment of three teenagers in a Finnish family with familial neutropenia is described. The mother was also diagnosed with neutropenia. At initial examination, the 15-year-old male and the 10-year-old female had severe periodontitis, whereas the 13-year-old male had oral ulcerations but no significant periodontal disease. The two siblings with periodontitis were treated and followed approximately 5 years. It was concluded that periodontal therapy including scaling, surgery, and use of antimicrobial agents can be successful in patients with familial neutropenia, and that such patients are not necessarily candidates for full mouth extraction. The role of granulocyte colony-stimulating factor in which was used in the treatment of these patients remains to be established.

    Chronic periodontitis is a progressive, infectious inflammation disease, caused by the dysbiosis of oral resident flora, leading to the destruction of periodontium. The onset of pathogenic microorganisms is the etiological factor of periodontitis, while the immuno-inflammatory response affects the progression of the disease. Under chronic periodontitis, oxidative stress occurs when excessive reactive oxygen species are produced and exceed the compensative capacity of the organism. Oxidative stress leads to the destruction of periodontium, in a direct way(damaging the biomolecule) or an indirect way(enhancing the produce of inflammatory cytokine and destructive enzymes). Therefore, as the antagonist of the reactive oxygen species, antioxidants may be helpful to treat the chronic periodontitis. This paper reviewed relevant literatures about the destructive role of excessive reactive oxygen species and protective role of antioxidants in chronic periodontitis.

    Periodontal disease, a relevant public health problem worldwide, is generally considered a common pathology of elderly people. In this respect, there is agreement about that nutritional status may be a modifying factor in the progression and healing of the periodontal tissues. Vitamins have been recommended as nutraceuticals for prevention and treatment of some pathological conditions, such as cardiovascular diseases, obesity or cancer. Thus, a systematic approach to determining how the different vitamin type could ameliorate periodontal risks or improve periodontal health is necessary to further the understanding of the potential benefits and risks of vitamins supplementation use. For this, a systematic review of English-written literature in PubMed until February 2018, which included both human and animal research on the relationship of each vitamin with periodontal disease, was conducted. Among all the analyzed vitamins those with antioxidant capacity and effects on immune system seem to be useful for prevention or improvement of periodontal disease, as well as those implicated in bone metabolism. In the first case, there are quite information in favor of various vitamins, mainly vitamin C, that is the most studied. In the second case, vitamin D seems to have the most relevant role.

    Background: The success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. The present study investigated the periodontal parameters at the end of the orthodontic treatment in patients with the aggressive periodontitis. Materials and Methods: Eight patients with an aggressive periodontal disease, extruded maxillary incisors, infrabony defects and probing depth of ≥5 mm were enrolled in this clinical trial (before, after). After periodontal therapy, orthodontic treatment was carried out for intrusion and alignment of teeth. Plaque index (PI), probing pocket depth (PPD), distance between incisal edge and interdental papilla, root length (RL), and defect dimensions (depth and width) were examined at the end of treatment and three as well as 6 months afterward. The data were subjected to repeated measure ANOVA test. P orthodontic approach would be a successful treatment with acceptable stability in the case of regular follow-up visits and controlled oral hygiene habits. PMID:24379862

    Deciphering the relative roles of heredity and environmental factors ("nature vs. nurture") in the pathogenesis of dental caries and diseases of the periodontium has occupied clinical and basic researchers for decades. Success in the endeavor has come more easily in the case of caries; the complex interactions that occur between host-response mechanisms and putative microbiologic pathogens in periodontal disease have made elucidation of genetic factors in disease susceptibility more difficult. In addition, during the 30-year period between 1958 and 1987, only meager resources were targeted toward the "nature" side of the nature/nurture dipole in periodontology. In this article, we present a brief history of the development of genetic epistemology, then describe the three main research mechanisms by which questions about the hereditary component of diseases in humans can be addressed. A critical discussion of the evidence for a hereditary component in caries susceptibility is next presented, also from a historical perspective. The evolution of knowledge concerning possible genetic ("endogenous", "idiotypic") factors in the pathogenesis of inflammatory periodontal disease is initiated with an analysis of some foreign-language (primarily German) literature that is likely to be unfamiliar to the reader. We identify a turning point at about 1960, when the periodontal research community turned away from genetics in favor of microbiology research. During the past five years, investigators have re-initiated the search for the hereditary component in susceptibility to common adult periodontal disease; this small but growing body of literature is reviewed. Recent applications of in vitro methods for genetic analyses in periodontal research are presented, with an eye toward a future in which persons who are at risk--genetically predisposed--to periodontal disease may be identified and targeted for interventive strategies. Critical is the realization that genes and environment

    Full Text Available Vascular disorders play a significant role in the development of dystrophic inflammatory process. There is a direct correlation between the degree of damage to blood vessels in the jaw and a depth of the destructive process in periodontal tissue. A certain role is played by endogenous factors, such as: age, vitamin deficiency, diabetes mellitus, essential hypertension and others. Clinical and epidemiological studies using pathological techniques showed significant changes in vascular wall of the artery in the periodontium, the interdental artery in particular.  Atherosclerosis, essential hypertension and periodontal pathology were proven to occur in individuals older than 40 years. The objective of the research was to determine periodontal tissue status in patients with stage II hypertension and generalized periodontitis of II degree of severity. Materials and methods. The study involved 36 patients with stage II hypertension and generalized periodontitis of II degree of severity (the main group. The patients’ age ranged from 35 to 54 years. The control group included 10 patients of corresponding age without generalized periodontitis and somatic pathology. To assess the status of periodontal tissues, we applied the Papillary-Marginal-Attached Index and the Community Periodontal Index of Treatment Needs. When diagnosing periodontal disease, the classification of M.F. Danilevskyi was used. Results. The analysis of the indicators of the Community Periodontal Index of Treatment Needs index showed the following results: in patients of the main group, the index was 2.38±0.07 points (p<0.001 pointing out a need for a course of professional oral hygiene. In patients of the control group, the index was 0.5±0.17 points indicating that there was no need for treatment, however, there was a need for improving oral hygiene. The indicators of the Papillary-Marginal-Attached Index in the main group were 55.49±1.96 points pointing out a severe degree of

    This review evaluates the possible relationship between periodontal disease and pre-eclampsia, a major pregnancy complication. A generalized inflammatory response plays an important role in the pathogenesis of pre-eclampsia. Because periodontal disease is a low-grade inflammatory state, periodontal disease might contribute to the pathogenesis of pre-eclampsia. A literature search of PubMed, EMBASE and CINAHL until August 2010 revealed 12 eligible observational studies and three randomized-controlled trials (RCTs). It appeared difficult to compare these studies, due to variations in definitions of periodontal disease and pre-eclampsia, timing of periodontal examination and inadequate control for confounding factors. Eight observational studies reported a positive association, while four studies found no association. None of the RTCs reported reductions in pre-eclamptic rate after periodontal therapy during pregnancy. Therefore, it is questionable whether periodontal disease plays a causal role in the pathogenesis of pre-eclampsia. The observed association in eight observational studies might be the result of induction of periodontal disease due to the pre-eclamptic state or it may be an epiphenomenon of an exaggerated inflammatory response to pregnancy. Larger RCTs with pre-eclampsia as the primary outcome and pathophysiological studies are required to explore causality and to dissect biological mechanisms involved. © 2010 John Wiley & Sons A/S.

    Full Text Available Background Periodontitis is one of the most common oral diseases associated with the host’s immune response against periodontopathogenic infection. Failure to accurately diagnose the stage of periodontitis has limited the ability to predict disease status. Therefore, we aimed to look for reliable diagnostic markers for detection or differentiation of early stage periodontitis using the immunoprotemic approach. Method In the present study, patient serum samples from four distinct stages of periodontitis (i.e., mild chronic, moderate chronic, severe chronic, and aggressive and healthy controls were subjected to two-dimensional gel electrophoresis (2-DE, followed by silver staining. Notably, we consistently identified 14 protein clusters in the sera of patients and normal controls. Results Overall, we found that protein levels were comparable between patients and controls, with the exception of the clusters corresponding to A1AT, HP, IGKC and KNG1 (p < 0.05. In addition, the immunogenicity of these proteins was analysed via immunoblotting, which revealed differential profiles for periodontal disease and controls. For this reason, IgM obtained from severe chronic periodontitis (CP sera could be employed as a suitable autoantibody for the detection of periodontitis. Discussion Taken together, the present study suggests that differentially expressed host immune response proteins could be used as potential biomarkers for screening periodontitis. Future studies exploring the diagnostic potential of such factors are warranted.

    Periodontal diseases constitute one of the major global oral health burdens, and periodontitis remains a major cause of tooth loss in adults worldwide. The World Health Organization recently reported that severe periodontitis exists in 5-20% of adult populations, and most children and adolescents exhibit signs of gingivitis. Likely reasons to account for these prevalent diseases include genetic, epigenetic, and environmental risk factors, as well as individual and socio-economic determinants. Currently, there are fundamental gaps in knowledge of such fundamental issues as the mechanisms of initiation and progression of periodontal diseases, which are undefined; inability to identify high-risk forms of gingivitis that progress to periodontitis; lack of evidence on how to prevent the diseases effectively; inability to detect disease activity and predict treatment efficacy; and limited information on the effects of integration of periodontal health as a part of the health care program designed to promote general health and prevent chronic diseases. In the present report, 12 basic, translational, and applied research areas have been proposed to address the issue of global periodontal health inequality. We believe that the oral health burden caused by periodontal diseases could be relieved significantly in the near future through an effective global collaboration.

    Periodontal disease is independently associated with cardiovascular disease. Identification of periodontal disease as a risk factor for incident ischemic stroke raises the possibility that regular dental care utilization may reduce the stroke risk. In the ARIC (Atherosclerosis Risk in Communities) study, pattern of dental visits were classified as regular or episodic dental care users. In the ancillary dental ARIC study, selected subjects from ARIC underwent fullmouth periodontal measurements collected at 6 sites per tooth and classified into 7 periodontal profile classes (PPCs). In the ARIC study 10 362 stroke-free participants, 584 participants had incident ischemic strokes over a 15-year period. In the dental ARIC study, 6736 dentate subjects were assessed for periodontal disease status using PPC with a total of 299 incident ischemic strokes over the 15-year period. The 7 levels of PPC showed a trend toward an increased stroke risk (χ 2 trend P periodontal disease). Periodontal disease was significantly associated with cardioembolic (hazard ratio, 2.6; 95% confidence interval, 1.2-5.6) and thrombotic (hazard ratio, 2.2; 95% confidence interval, 1.3-3.8) stroke subtypes. Regular dental care utilization was associated with lower adjusted stroke risk (hazard ratio, 0.77; 95% confidence interval, 0.63-0.94). We confirm an independent association between periodontal disease and incident stroke risk, particularly cardioembolic and thrombotic stroke subtype. Further, we report that regular dental care utilization may lower this risk for stroke. © 2018 American Heart Association, Inc.

    2012-12-01

    Full Text Available Insulin resistance (IR is now considered as a chronic and low level inflammatory condition. It is closely related to altered glucose tolerance, hypertriglyceridemia, abdominal obesity, and coronary heart disease. IR is accompanied by the increase in the levels of inflammatory cytokines like interleukin-1 and 6, tumor necrosis factor-α. These inflammatory cytokines also play a crucial part in pathogenesis and progression of insulin resistance. Periodontitis is the commonest of oral diseases, affecting tooth investing tissues. Pro-inflammatory cytokines are released in the disease process of periodontitis. Periodontitis can be attributed with exacerbation of IR. Data in the literature supports a "two way relationship" between diabetes and periodontitis. Periodontitis is asymptomatic in the initial stages of disease process and it often escapes diagnosis. This review presents the blurred nexus between periodontitis and IR, underlining the pathophysiology of the insidious link. The knowledge of the association between periodontitis and IR can be valuable in planning effectual treatment modalities for subjects with altered glucose homeostasis and diabetics. Presently, the studies supporting this association are miniscule. Further studies are mandatory to substantiate the role of periodontitis in the deterioration of IR.

    Virginia Woolf y Vincent Van Gogh, trágicos genios del arte, son quizá las figuras que más encarnan ante el público occidental la antigua pregunta que todavía permanece: ¿La enfermedad crea al artista? Tras un brote psicótico, Virginia Woolf dijo haber escuchado cantar a los pájaros en griego, y años más tarde lo incluyó en la caracterización de Septimus, protagonista en La Señora Dalloway:

    Por su parte, Van Gogh escribió en la segunda carta a su hermano Théo, en septiembre de 1889:

    Periodontitis and type 2 diabetes mellitus are known to be associated. The relationship between periodontal microbiota and early diabetes risk has not been studied. We investigated the association between periodontal bacteria and prediabetes prevalence among diabetes-free adults. ORIGINS (the Oral Infections, Glucose Intolerance and Insulin Resistance Study) cross sectionally enrolled 300 diabetes-free adults aged 20 to 55 y (mean ± SD, 34 ± 10 y; 77% female). Prediabetes was defined as follows: 1) hemoglobin A1c values ranging from 5.7% to 6.4% or 2) fasting plasma glucose ranging from 100 to 125 mg/dL. In 1,188 subgingival plaque samples, 11 bacterial species were assessed at baseline, including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, and Actinomyces naeslundii. Full-mouth clinical periodontal examinations were performed, and participants were defined as having no/mild periodontitis vs. moderate/severe periodontitis per the definition of the Centers for Disease Control and Prevention / American Academy of Periodontology. Modified Poisson regression evaluated prediabetes prevalence across bacterial tertiles. Prevalence ratios and 95% confidence intervals for third vs. first tertiles are presented. All analyses were adjusted for cardiometabolic risk factors. All results presented currently arise from the baseline cross section. Prediabetes prevalence was 18%, and 58% of participants had moderate/severe periodontitis. Prevalence ratios (95% confidence intervals) summarizing associations between bacterial levels and prediabetes were as follows: A. actinomycetemcomitans, 2.48 (1.34, 4.58), P = 0.004; P. gingivalis, 3.41 (1.78, 6.58), P = 0.0003; T. denticola, 1.99 (0.992, 4.00), P = 0.052; T. forsythia, 1.95 (1.0, 3.84), P = 0.05; A. naeslundii, 0.46 (0.25, 0.85), P = 0.01.

    Periodontitis is a ubiquitous and irreversible inflammatory condition and represents a significant public health burden. Severe periodontitis affects over 11% of adults, is a major cause of tooth loss impacting negatively upon speech, nutrition, quality of life and self-esteem, and has systemic inflammatory consequences. Periodontitis is preventable and treatment leads to reduced rates of tooth loss and improved quality of life. However, successful treatment necessitates behaviour change in patients to address lifestyle risk factors (e.g. smoking) and, most importantly, to attain and sustain high standards of daily plaque removal, lifelong. While mechanical plaque removal remains the bedrock of successful periodontal disease management, in high-risk patients it appears that the critical threshold for plaque accumulation to trigger periodontitis is low, and such patients may benefit from adjunctive agents for primary prevention of periodontitis. The aims of this working group were to systematically review the evidence for primary prevention of periodontitis by preventing gingivitis via four approaches: 1) the efficacy of mechanical self-administered plaque control regimes; 2) the efficacy of self-administered inter-dental mechanical plaque control; 3) the efficacy of adjunctive chemical plaque control; and 4) anti-inflammatory (sole or adjunctive) approaches. Two meta-reviews (mechanical plaque removal) and two traditional systematic reviews (chemical plaque control/anti-inflammatory agents) formed the basis of this consensus. Data support the belief that professionally administered plaque control significantly improves gingival inflammation and lowers plaque scores, with some evidence that reinforcement of oral hygiene provides further benefit. Re-chargeable power toothbrushes provide small but statistically significant additional reductions in gingival inflammation and plaque levels. Flossing cannot be recommended other than for sites of gingival and periodontal

    Periodontitis is a systemic and chronic inflammatory disease associated with multiple physical conditions. Distress and depression are other problems affecting the progression of periodontitis. However, the causal relationship between depression and periodontitis has not been adequately investigated. This aim of this study was to determine the association between periodontitis and the subsequent development of depression.We identified 12,708 patients with newly diagnosed periodontitis from 2000 to 2005 and 50,832 frequency-matched individuals without periodontitis. Both groups were followed until diagnosed with depression, withdrawal from the National Health Insurance program, or the end of 2011. The association between periodontitis and depressio was analyzed using Cox proportional hazard regression models.The incidence density rate of depression was higher in the periodontitis group than in the nonperiodontitis group, with an adjusted hazard ratio of 1.73 (95% confidence interval 1.58-1.89) when adjusting for sex, age, and comorbidity. Cox models revealed that periodontitis was an independent risk factor for depression in patients, except for comorbidities of diabetes mellitus (DM), alcohol abuse, and cancer.Periodontitis may increase the risk of subsequent depression and was suggested an independent risk factor regardless of sex, age, and most comorbidities. However, DM, alcohol abuse, and cancer may prevent the development of subsequent depression because of DM treatment, the paradoxical effect of alcohol, and emotional distress to cancer, respectively. Prospective studies on the relationship between periodontitis and depression are warranted.

    Periodontal diseases are prevalent both in developed and developing countries and affect about 20-50% of global population. High prevalence of periodontal disease in adolescents, adults, and older individuals makes it a public health concern. Several risk factors such as smoking, poor oral hygiene, diabetes, medication, age, hereditary, and stress are related to periodontal diseases. Robust evidence shows the association of periodontal diseases with systemic diseases such as cardiovascular disease, diabetes, and adverse pregnancy outcomes. Periodontal disease is likely to cause 19% increase in the risk of cardiovascular disease, and this increase in relative risk reaches to 44% among individuals aged 65 years and over. Type 2 diabetic individuals with severe form of periodontal disease have 3.2 times greater mortality risk compared with individuals with no or mild periodontitis. Periodontal therapy has been shown to improve glycemic control in type 2 diabetic subjects. Periodontitis is related to maternal infection, preterm birth, low birth weight, and preeclampsia. Oral disease prevention strategies should be incorporated in chronic systemic disease preventive initiatives to curtail the burden of disease in populations. The reduction in the incidence and prevalence of periodontal disease can reduce its associated systemic diseases and can also minimize their financial impact on the health-care systems. It is hoped that medical, dental practitioners, and other health-care professionals will get familiar with perio-systemic link and risk factors, and need to refer to the specialized dental or periodontal care.

    Apical periodontitis is a chronic inflammatory disorder of periradicular tissues caused by aetiological agents of endodontic origin. Persistent apical periodontitis occurs when root canal treatment of apical periodontitis has not adequately eliminated intraradicular infection. Problems that lead to persistent apical periodontitis include: inadequate aseptic control, poor access cavity design, missed canals, inadequate instrumentation, debridement and leaking temporary or permanent restorations. Even when the most stringent procedures are followed, apical periodontitis may still persist as asymptomatic radiolucencies, because of the complexity of the root canal system formed by the main and accessory canals, their ramifications and anastomoses where residual infection can persist. Further, there are extraradicular factors -- located within the inflamed periapical tissue -- that can interfere with post-treatment healing of apical periodontitis. The causes of apical periodontitis persisting after root canal treatment have not been well characterized. During the 1990s, a series of investigations have shown that there are six biological factors that lead to asymptomatic radiolucencies persisting after root canal treatment. These are: (i) intraradicular infection persisting in the complex apical root canal system; (ii) extraradicular infection, generally in the form of periapical actinomycosis; (iii) extruded root canal filling or other exogenous materials that cause a foreign body reaction; (iv) accumulation of endogenous cholesterol crystals that irritate periapical tissues; (v) true cystic lesions, and (vi) scar tissue healing of the lesion. This article provides a comprehensive overview of the causative factors of non-resolving periapical lesions that are seen as asymptomatic radiolucencies post-treatment.

    This study aimed to assess the relationship between socio-economic factors and community periodontal treatment needs in Korea. Data were obtained from the year 2009 Korean National Health and Nutrition Examination Survey. Our analysis included 7510 survey participants over the age of 19 years. To assess the relationship between socio-economic factors and the need for periodontal scaling, we performed multivariate logistic regression analyses for data with a complex sampling structure. PASW statistics 19.0 (SPSS Inc., Chicago, IL, USA) was used to perform the statistical analyses, and the results were expressed as odds ratios (OR) with corresponding 95% confidence intervals (CIs). A very high percentage of Korean adults required periodontal scaling (71.5%). After adjusting for sex, age, and socio-economic factors, the need for periodontal scaling was associated with low levels of education (OR: 1.41, 95% CI: 1.03-1.93), low incomes (OR: 1.27, 95% CI: 1.01-1.60), employment as a service and sales worker (OR: 1.39, 95% CI: 1.10-1.77), and employment as a manual worker (OR: 1.31, 95% CI: 1.02-1.69). In South Korea, the need for periodontal scaling was associated with socio-economic factors, such as low levels of education, low incomes, employment as a service and sales worker and employment as a manual worker. Consequently, clinical and community dental hygienists should consider adults with these risk factors as belonging to high-priority subgroups to whom they should respond first. © 2014 John Wiley & Sons A/S.

    Full Text Available Background: Periodontal infections, which serve as a reservoir of inflammatory mediators, may pose a threat to the fetal-placental unit and cause adverse pregnancy outcomes. Objective: The aim of this study was assessing the periodontal status of women during puerperium and determining the possible relationship between their periodontal disease and low birth weight delivery. Materials and Methods: This was a case-control study. The sample included 88 ex-pregnant women were seen at maternity hospitals of Yazd, Iran. Half of the mothers had low birth babies (LBW (birth weight below 2500g- case group and the others had normal weight babies (>2500g- control group. The mothers’ data were obtained from medical files, interview and periodontal clinical examination carried out up to 3 days after delivery. Bleeding on probing, presence of supra-gingival calculus and CPITN (Community Periodontal Index for Treatment Needs were used for periodontal assessment Results: Among the known risk factors of LBW babies, history of previous LBW infant among case mothers reached statistical significance (p=0.0081, Student t-test. Mothers of LBW infants had less healthy areas of gingiva (p=0.042, and more deep pockets (p=0.0006, Mann-Whitney test. Conclusion: The maternal periodontal disease can be a potential independent risk factor for LBW.

    Disease of systemic lupus erythematosus (SLE) and periodontal disease (PD) shares the common multiple characteristics. The aims of the present study were to evaluate the prevalence and severity of periodontal disease in Chinese SLE patients and to determine the association between SLE features and periodontal parameters. A cross-sectional study of 108 SLE patients together with 108 age- and sex-matched healthy controls was made. Periodontal status was conducted by two dentists independently. Sociodemographic characteristics, lifestyle factors, medication use, and clinical parameters were also assessed. The periodontal status was significantly worse in SLE patients compared to controls. In univariate logistic regression, SLE had a significant 2.78-fold [95% confidence interval (CI) 1.60-4.82] increase in odds of periodontitis compared to healthy controls. Adjusted for potential risk factors, patients with SLE had 13.98-fold (95% CI 5.10-38.33) increased odds against controls. In multiple linear regression model, the independent variable negatively and significantly associated with gingival index was education (P = 0.005); conversely, disease activity (P periodontitis of SLE in multivariate logistic regression (OR 1.348; 95% CI: 1.183-1.536, P < 0.001). Chinese SLE patients were likely to suffer from higher odds of PD. These findings confirmed the importance of early interventions in combination with medical therapy. It is necessary for a close collaboration between dentists and clinicians when treating those patients.

    Periodontal diseases are a major public health concern leading to tooth loss and also shown to be associated with several chronic systemic diseases. Smoking is a major risk factor for developing numerous systemic diseases, as well as periodontitis. While it is clear that smokers have a significantly enhanced risk for developing periodontitis leading to tooth loss, the population varies with regards to susceptibility to disease associated with smoking. This investigation focuses on identifying differences in four broad sets of variables consisting of: (a) host response molecules, (b) periodontal clinical parameters, (c) antibody measures for periodontal pathogens and oral commensal bacteria challenge, and (d) other variables of interest in a smoking population with (n = 171) and without periodontitis (n = 117). Subsequently, Bayesian network structured learning techniques (BNSL) techniques were used to investigate potential associations and cross-talk between the four broad sets of variables. BNSL revealed two broad communities with markedly different topology between the non-periodontitis and periodontitis smoking population. Confidence of the edges in the resulting network also showed marked variations within and between the periodontitis and non-periodontitis groups. The results presented validated known associations, as well as discovered new ones with minimal precedence that may warrant further investigation and novel hypothesis generation. Cross-talk between the clinical variables and antibody profiles of bacteria were especially pronounced in the case of periodontitis and mediated by the antibody response profile to P. gingivalis.

    The general dental practitioner and paediatric dentist are in a unique position to identify and distinguish between a seemingly innocuous condition that may be a normal physiological aberration or an early sign of severe destructive periodontal disease. Although severe destructive periodontal conditions are uncommon in children, it is essential that children receive a periodontal screening as part of their regular dental examination. Early diagnosis ensures a high likelihood of a successful therapeutic outcome, primarily by reduction of aetiologic factors, remedial therapy and development of an effective maintenance protocol. This prevents the recurrence and progression of disease and reduces the incidence of tooth loss. In the first article, we discussed the classification, plaque-induced and non plaque-induced gingival diseases, localized and generalized forms of chronic as well as aggressive periodontitis. In this second article, we discuss periodontitis as a manifestation of systemic disease, necrotizing periodontal diseases, periodontal screening and basic periodontal examination, and treatment of periodontal diseases in children and adolescents. Incorporation of periodontal screening in regular dental examination by dentists can help in early diagnosis and treatment of periodontal diseases. This could prevent further progression of disease and reduce the frequency of tooth loss.

Methods: A total of 200 subjects including two groups. Group A- 34 subjects undergoing tooth extraction with periodontitis, 46 subjects undergoing tooth extraction without periodontitis and 40 healthy controls. Group B: 40 confirmed cases of IE (17 with and 23 without periodontitis and 40 healthy controls. Subgingival plaque and blood samples were obtained and processed by standard procedures. Results: A total of 53 blood samples (66.25% yielded positive cultures after tooth extraction. The relationship between the presence of periodontitis and a positive blood culture was significantly higher (p = 0.05 for tooth extraction cases with periodontitis (79.40% than tooth extraction cases without periodontitis (56.50%. Periodontitis was observed in 42.5% of IE cases. Out of the 40 patients of IE, the blood samples yielded 40 different isolates, majority were viridans streptococci 15 (37.5% and staphylococci nine (22.5%. No statistically significant difference was observed between the subgingival plaque and blood isolates of periodontitis in both the groups, indicating similarity of biotypes of viridans streptococci isolated from the blood and the subgingival plaque. Similarity was also observed between the antibiogram profiles of viridans streptococci from both the groups. Conclusions: Periodontitis enhances viridans streptococcal bacteremia and may be a potential risk factor for IE. Keywords: Infective endocarditis, Periodontitis, Viridans group streptococci

    Lupus erythematosus is considered to be a high risk factor for periodontitis. As an autoimmune disease of unknown origin, cutaneous lupus erythematosus (CLE) is subdivided into 3 categories: chronic (CCLE), subacute (SCLE), and acute (ACLE). While the ACLE has a high prevalence of conjunctive periodontal lesions, aggressive periodontitis in patients with CCLE has been rarely reported. This article describes the case of a patient diagnosed with aggressive periodontitis. Three months after the diagnosis of periodontitis, the patient experienced advancing hair loss (alopecia), pale fingers and toes, as well as edema in the legs and around the eyes. Skin biopsy showed follicular hyperkeratosis with perivascular mononuclear cell infiltrate. Colliquation of the basal cells, thickening of the basal lamina, and vacuolar degeneration of basal keratinocytes were also found. A lupus band test was positive, and diagnosis of CCLE was established. Three months following the treatment of lupus with antimalarial agents, the periodontal condition became stable with no further exacerbation or progression of the existing periodontitis. An 11-month postsurgical follow-up revealed stable periodontal and general medical conditions. A patient's medical history should be re-evaluated in the event of recurrence of periodontal lesions refractory to periodontal treatment. The control of systemic conditions like lupus erythematosus is essential for a good prognosis in the treatment of periodontitis as well as for the general health of the patient.

    Background: A lot of studies have shown periodontal diseases as a risk factor for adverse pregnancy outcomes. The association between periodontitis and preeclampsia has been studied recently with controversy. Considering the importance of preventing preeclampsia as a dangerous and life-threatening disease in pregnant women, the present study was carried out. Methods: Two hundred and ten pregnant women participated in this case-control study (105 controls & 105 cases) during years 2007 and 2008. Preeclamptic cases were defined as blood pressure ≥140/90mmHg and proteinuria +1. Control group were pregnant women with normal blood pressure without proteinuria. Both groups were examined during 48 hours after child delivery. Plaque Index (PLI), Pocket Depth (PD), Clinical Attachment Level (CAL), Bleeding On Probing (BOP), Gingival Recession (GR) were measured on all teeth except for third molars and recorded as periodontal examination. Data was analyzed using t-test, chi-square, and Mann-Whitney U statistical tests. Results: There was no significant difference between the two study groups for PD. CAL, GR, BOP significantly increased in the case group (P< 0.02). This study showed that preeclamptic cases were more likely to develop periodontal disease (P< 0.0001). Eighty three percent of the control group and 95% of the case group had periodontal disease (P< 0.005) which had shown that preeclamptic cases were 4.1 times more likely to have periodontal disease (OR= 4.1). Conclusion: Preeclamptic cases significantly had higher attachment loss and gingival recession than the control group. PMID:23113094

    Situación Actual de Colombia.

    La enfermedad de Chagas o tripanosomiasis americana es una enfermedad parasitaria crónica causada por un protozoario flagelado el Trypanosoma cruzi, descrito por primera vez por Carlos Chagas, médico brasileño, a comienzos de este siglo y en su honor se denominó la enfermedad que lleva su nombre.

    Este parásito normalmente se transmite al ser humano a través de insectos triatomíneos estrictamente hematófagos de la familia Reduviidae, en el momento en que perforan la piel para succionar la sangre que los alimenta.

    Sin embargo, no se inocula directamente por intermedio de las estructuras bucales del insecto en el momento de la picadura como en el caso de las tripanosomiasis africanas, si no que se deposita pasivamente en la piel a través de las heces del insecto, penetrando en el cuerpo por la herida que causa la picadura u otras abrasiones de la piel o de la mucosa. El T. cruzi, también puede transmitirse por infección congénita, por transfusión de sangre contaminada o por el transplante de órganos contaminados. El ciclo vital del parásito es largo y complejo y su desarrollo tiene varias etapas, tanto en el vector triatomineo como en el huésped vertebrado .

    La Enfermedad de Chagas constituye una amenaza permanente para casi la cuarta parte de toda la población de América Latina. Si bien la enfermedad se encuentra presente en toda América Central y del Sur, sus manifestaciones y características epidemiológicas son altamente variables entre una y otra zona endémica. Existe una gran diversidad en las tasas de prevalencia, formas de transmisión, características parasitarias, patología clínica, vectores y reservorios.

    Más que cualquier otra enfermedad parasitaria, la enfermedad de Chagas se relaciona con el desarrollo económico y social de la población: los insectos triatomineos y las enfermedades que ellos transmiten existirán mientras en

    Periodontal disease is one of the most prevalent oral diseases. An association between this disease and pregnancy has been suggested, but available findings are controversial. We evaluated the expression levels of interleukins (IL-1β and IL-6), tumor necrosis factor-alpha (TNF-α), and inducible nitric oxide synthase (iNOS) in pregnant women with and without periodontal disease in comparison with non-pregnant women with and without periodontal disease since studies have suggested a relationship between periodontitis and the expression levels of these genes. The women in the sample were distributed into four groups: pregnant and non-pregnant women, with or without periodontal disease, a total of 32 women. The periodontal condition was evaluated according to the probing depth, clinical attachment level and bleeding on probing. Analysis of gene expression was performed by real-time PCR. Comparisons were made of the level of gene expression among the four groups. Expression of IL-1β in the non-pregnant women with periodontal disease was 12.6 times higher than in the non-pregnant women without periodontal disease (P periodontal disease was 3.5 times higher than in the pregnant women with periodontal disease (P periodontal disease in comparison with expression of the same genes in non-pregnant women with and without periodontal disease, suggesting that periodontal disease is not influenced by pregnancy.

    Periodontal regeneration can be defined as complete restoration of lost periodontal tissues to their original architecture and function. A variety of treatment modalities have been proposed to achieve it. Plasma rich in growth factors (PRGF) is a concentrated suspension of growth factors that promotes restoration of lost periodontal tissues. The objective of the present study is to assess the effect of PRGF associated with guided tissue regeneration (GTR) versus GTR only in the treatment of intrabony defects (IBDs) in patients with chronic periodontitis (CP). Patients with CP (n = 14) with 42 contralateral 2- and 3-walled defects were randomly assigned to test (PRGF+GTR) and control (GTR alone) treatment groups. Clinical and radiographic assessments performed at baseline and after 6 months were: 1) gingival index (GI), 2) probing depth (PD), 3) clinical attachment level (CAL), 4) radiologic defect depth, and 5) bone fill. Comparison of parameters measured at baseline and after 6 months showed mean PD reduction of 3.37 ± 1.62 mm in the control group (P <0.001) and 4.13 ± 1.59 mm in the test group (P <0.001). There was a significant difference in mean change in CAL (P <0.001) in the control group (5.42 ± 1.99) and the test group (5.99 ± 1.77). Mean change in GI was 1.89 ± 0.32 and 1.68 ± 0.58 in the control group and test group, respectively, and the difference was statistically significant (P <0.001). When compared between groups, clinical parameters did not show any statistically significant variations. Mean radiographic bone fill was 1.06 ± 0.81 and 1.0 ± 0.97 in the control group and test group, respectively. However, the difference was not statistically significant. PRGF with GTR, as well as GTR alone, was effective in improving clinical and radiographic parameters of patients with CP at the 6-month follow-up. There was no additive effect of PRGF when used along with GTR in the treatment of IBDs in patients with CP in terms of both clinical and

    Host Modulation Therapy (HMT) is a treatment concept that reduces tissue destruction and stabilizes or even regenerates inflammatory tissue by modifying host response factors. It has been used for treating osteoporosis and arthritis for several decades. However, its use in dentistry has only been recently reported. The objective of this article is to present a review of the various literatures available on HMT and also its role as adjunct therapy in periodontics. For identifying studies for this review, a PUBMED search was carried out in 2013 for all articles published till December 2012. The search was restricted to English language publications only. Longitudinal prospective and retrospective studies were included in the search. The key words used were: Host Modulation Therapy; Sub antimicrobial dose doxycycline and Non-Surgical Periodontal Therapy. The main outcomes sought were host modulation therapeutics in periodontics. Exclusion criteria included cross sectional studies, short case series as well as studies with short follow-up periods. There is a paucity of literature on HMT in periodontics although the only drug approved by United States Food and Drug Administration (FDA) is a subantimicrobial dose of doxycycline (SDD) with highly predictable results as a host modulating agent in periodontal diseases and also an effective adjunctive therapy in various diseases of periodontium. However, more randomized controlled trials are needed to obtain clinical guidelines on the usage of other host modulating agents as adjunct as well as definite therapy for periodontal diseases. SDD is an effective adjunct therapy when used in dosage of 20mg twice daily for minimum 3 months duration in various periodontal diseases with predictable clinical outcomes. It is also recommended that future clinical research on anti cytokine drugs, chemically modified tetracycline and other HMT agents should be conducted so that new drugs are available with highly predictable results.

    Full Text Available Introduction: Although bacterial plaque is regarded as the major cause of periodontitis, the role of smoking as an important risk factor has been established in the progression of periodontal disease. Thus, the present study aimed to evaluate knowledge and attitude of patients with periodontitis concerning effects of smoking on periodontal health. Method: In this descriptive cross-sectional study, 300 patients with periodontitis, aged between 18-74 years, were selected via convenience sampling out of patients referred to Periodontology Department of Shahid Sadoughi Dental Faculty and Khatam Alanbia professional clinic of Yazd. The study data were collected using a questionnaire, which were then analyzed by SPSS software (ver. 17 applying Chi-square, T-test and ANOVA statistical tests. Results: The mean total scores of patients' knowledge and attitude in regard with smoking effect on periodontal health were reported 86.7±18.4 and 48.1±7.3, respectively. A significant relationship was observed between knowledge and attitude with students' educational level. In the present study, 42% of smokers tried to quit smoking at least once, among which 14.3% of cases occured due to oral and dental health as well as consultation with dentists.
