    For this study 20 patients with periodontal disease were selected. The treatment required for all of then was the gingivectomy, a ressective periodontal surgery. This technique consists of removing the whole excess of gingival tissue with the intent of reestablishing the anatomy and the correct function. The gingival area was submitted to 2 different wavelengths and then histologically analysed to search for alterations, mainly concerning mast cells behavior, a blood cell responsible, among other things, for blood vases enlargement. During the surgical procedure each gingival area was submitted to infrared low intensity laser ({lambda} = 785 nm) or to red laser ({lambda} = 688 nm), both with 50 mW of power and fluence of 8 J/cm{sup 2}. A third area was analysed, the control area, in which no laser treatment was employed. The samples were fixated in formol, cut and stained by hematoxyline eosine and toluidine blue. Based on the result we can conclude: the 2 wavelengths used in this study led to the reduction in the number of mast cells present in the tissue as well as to the increase on the degranulation of the remaining mast cells, considered statistically significant taken the degranulation index and; there was no significant difference caused by the action of the two laser wavelengths {lambda}=785 nm and {lambda}=688 nm -50 mW of power and fluence of 8 J/cm{sup 2}-, over the degranulation of the mast cells; the length and width of the randomly chosen blood vases were not statistically different among the analysed groups.

    Full Text Available The Bolsa Escola (‘school stipend’ and its successor the Bolsa Familia (‘family stipend’ schemes have formed a crucial and successful part of Brazil’s welfare program. Bolsa Escola provided aid to Brazil’s poorest families on the condition that their children attended school, and Bolsa Familia has extended this idea, giving aid on the condition that children both attend school and receive vaccinations. Bolsa Familia is currently the largest Conditional Cash Transfer Program (CCTP in the world, costing roughly 0.5% of Brazilian GDP and helping around 11.2 million families (around 44 million Brazilians, constituting roughly one fifth of the population. Multilateral institutions have praised the schemes, and they are setting a leading example to other developing nations. In 2005, Paul Wolfowitz (former president of the World Bank said, ‘Bolsa Familia has already become a highly praised model of effective social policy. Countries around the world are drawing lessons from Brazil’s experience and are trying to produce the same results for their own people’.

    Full Text Available Periodontitis is an infectious disease caused by predominantly gram-negative, anaerobic bacteria like P. gingivalis, A. actinomycetemcomitans T. denticola and T. forsythus etc.. Various immunization approaches both as active and passive immunization, against periodontal pathogens have been explored either using the whole microorganism or their specific virulence factors. Non-human primate and other study models have demonstrated raised production of specific antibody titers against various antigens without any recognizable systemic side-effects. But, the current status of our understanding in the field of vaccines against periodontal disease is incomplete. Ongoing research & collaborative efforts can result in development of functional periodontal vaccine for human use in future.

    In general, the new term "localized aggressive periodontitis" replaces what was previously known as "localized juvenile periodontitis." Similarly, "generalized aggressive periodontitis" replaces what used to be called "generalized juvenile periodontitis." Aggressive periodontitis is a specific type of periodontitis with clearly identifiable clinical and laboratory findings, making it sufficiently different from chronic periodontitis and warranting separate classification. Not all the characteristics must be present to assign a diagnosis or classify the disease. The diagnosis may be based on clinical, radiographic, and historical data, and laboratory testing may not be essential for assigning a diagnosis.

  18. Periodontal diagnostics.

    Kinane, D F

    2000-10-01

    Periodontitis affects a subset of the population and our current thinking is that progression of periodontal disease may be either continuous or cyclical (burst hypothesis). These features make screening and diagnostic tools desirable in the management of this disease. Although many potential markers exist, several difficulties hamper our ability to declare them diagnostic tests with proven utility. The 'gold standard' for active periodontal disease is not available and inflammation due to gingivally confined lesions (gingivitis) and periodontal inflammation which results in attachment loss is a potential confounder of any test based on assessing the host response elements of the disease. The current absence of proof for the progression of periodontal disease i.e., whether or not the burst hypothesis is correct, is a further problem. Although much is written about the need for markers of current or future disease which will prevent us from overtreating pockets, the time, effort and cost involved in testing these sites has to be balanced against the relative ease and speed of routine therapy such as root planing. In addition, we are still some way from the development and validation of reliable host or microbial testing methods. In terms of screening tests for diseases such as the early-onset forms of periodontitis, the research and development on diagnostic tools involving genetic polymorphisms, specific genes, systemic antibodies or leucocyte cell surface markers of the patients, may become a clinical reality in time. One could envisage chairside tests using blood from thumb pricks being capable of determining a young individual's risk of developing disease at a later age, and thus the need for a timely prevention programme. Before applying any test we should reconsider what treatment planning effects a positive or negative result will have, and any test which does not influence the treatment plan is redundant. Whether periodontal diagnostic tests will be

    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.

    2006-03-01

    Full Text Available A doença periodontal é morbidade com alta prevalência na população mundial. É causada pelo acúmulo de componentes microbianos do biofilme dental no interior das áreas subgengivais do periodonto, desencadeando processo inflamatório que afeta as estruturas de suporte dental, resultando em formação de bolsa periodontal e perda dos dentes, se não tratada. O tratamento convencional consiste de raspagem e alisamento radicular, associado ou não ao uso de antimicrobianos de ação sistêmica, o que implica altas doses, porém com eficácia reduzida, efeitos adversos e dificuldades de adesão ao tratamento por parte do paciente. Nas últimas décadas, o tratamento tem sido otimizado pelo uso de sistemas de liberação de fármaco intrabolsa periodontal, com a vantagem de liberar o fármaco no local de ação, possibilitando prolongar e/ou controlar sua concentração. A presente revisão aborda os principais sistemas de liberação de fármaco intrabolsa periodontal, o potencial de utilização, assim como os protocolos disponíveis para a avaliação da efetividade dos mesmos na terapia periodontal.Periodontal disease is very common in the world population. It is caused by the accumulation of microbial components of the dental biofilm inside the subgingival areas, producing an inflammatory process that affects the supporting structures of tooth, periodontal pockets and loss of the teeth, if not treated. The conventional treatment consists of tooth surface mechanical cleaning and root planning, associated or not to the systemic use of high concentrations of antibiotics, but with reduced effectiveness, and adverse effects. The patient compliance to the therapeutic is committed too. In the last decades, the treatment has been optimized for the use of drug delivery systems to the periodontal pocket, with the advantage of delivering the drug in the specific site, sustaining and/or controlling the drug concentration.

    This paper investigates the impact of the Bolsa Família Program on the immunization of children from 0 to 6 years of age in Brazil and its regions. The Bolsa Família program is a conditional cash transfer program. One of its conditionalities is the compliance of children with the immunization schedule ordered by the Ministry of Health. The evaluation was performed using the Propensity Score Matching technique. We used data from a survey conducted in 2005 evaluating the program - Pesquisa de Avaliação de Impacto do Programa Bolsa Família. The main findings suggest that the Bolsa Família Program does not affect the immunization status of children.

    Over the past 20 years, numerous investigations have demonstrated epidemiologically and biologically that smoking is one of the most significant risk factors with respect to the development and progression of periodontal disease. In terms of the mechanism via which smoking influences periodontitis progression, various factors contribute to the deleterious periodontal effects of smoking, including alteration of both microbial and host response factors. Furthermore, since it is well known that smoking is also a risk factor of osteoporosis, the combination of smoking with osteoporosis further enhances the risk of periodontal disease. Recent investigations reported that passive smoking exposure may be a risk factor of periodontal disease and may stimulate inflammatory responses of periodontal tissue.

    2014-03-01

    The goal of regenerative periodontal therapy is to completely restore the tooth's supporting apparatus that has been lost due to inflammatory periodontal disease or injury. It is characterized by formation of new cementum with inserting collagen fibers, new periodontal ligament, and new alveolar bone. Indeed conventional, nonsurgical, and surgical periodontal therapy usually result in clinical improvements evidenced by probing depth reduction and clinical attachment gain, but the healing occurs predominantly through formation of a long junctional epithelium and no or only unpredictable periodontal regeneration. Therefore, there is an ongoing search for new materials and improved surgical techniques, with the aim of predictably promoting periodontal wound healing/regeneration and improving the clinical outcome. This article attempts to provide the clinician with an overview of the most important biologic events involved in periodontal wound healing/ regeneration and on the criteria on how to select the appropriate regenerative material and surgical technique in order to optimize the clinical outcomes.

    Over the last decade, there has been a great improvement in the oral health of Brazilians. However, such a trend was not observed among five-year-old children. Dental caries are determined by the interplay between biological and behavioral factors that are shaped by broader socioeconomic determinants. It is well established that dental disease is concentrated in socially disadvantaged populations. To reduce social and health inequalities, the Brazilian government created Family Health Program (ESF), and the Bolsa Família Program, the Brazilian conditional cash transfer program (Bolsa Família Program). The aim of this study was to examine the oral health care and promotion provided by the Family Health Teams to children and caregivers covered by the Bolsa Família Program. Data was collected through interviews with three groups of participants: 1) dentists working for the Family Health Program; 2) Family Health Program professionals supervising the Bolsa Família Program health conditionalities (Bolsa Família Program supervisors); and 3) parents/caregivers of children covered by the Bolsa Família Program. A pretested questionnaire included sociodemographic, Bolsa Família Program, oral health promotion, dental prevention and dental treatment questions. The results showed that most dentists performed no systematic efforts to promote oral health care to children covered by the Bolsa Família Program (93.3%; n = 69) or to their parents/caregivers (74.3%; n = 55). Many dentists (33.8%) did not provide oral health care to children covered by the Bolsa Família Program because they felt it was beyond their responsibilities. Nearly all Bolsa Família Program supervisors (97.3%; n = 72) supported the inclusion of oral health care in the health conditionality of the Bolsa Família Program, but 82.4% (n = 61) stated they did not promote oral health activities to children covered by the Bolsa Família Program. Children in the routine care setting were more often referred

Apesar de o programa ter atingido sua meta de atendimento de 11 milhões de domicílios ao final de 2006, há evidências de que cerca de 3,4 milhões de domicílios elegíveis ainda se encontram a descoberto. Simulações evidenciam que garantir a cobertura de todos os domicílios elegíveis tem maior impacto sobre os indicadores de pobreza que conceder o novo benefício, criado em 2008, aos jovens nos domicílios já atendidos pelo programa.After a brief retrospective of the evolution of income transfer programs in Brazil, this article uses information from the 2004 and 2006 official national household survey (PNAD in order to analyze the recent evolution of the Bolsa Familia program regarding targeting and coverage. Despite the fact that the BF met its goal of assisting 11 million households by the end of 2006, still around 3.4 million eligible households do not receive the transfer benefit. Simulations show that guaranteeing the basic income transfer to all eligible households has a stronger impact on poverty indicators than to grant the new benefit - created in 2008 - to youngsters who live in the already assisted households.

    Full Text Available INTRODUÇÃO: A doença periodontal pode ter seu início na infância e na adolescência, e progredir lentamente ao longo da vida. Em universitários, a forma mais comum e prevalente da doença é a gengivite. OBJETIVO: Mensurar a condição de saúde periodontal de uma amostra de universitários e verificar existência da associação com variáveis sociodemográficas e os fatores de risco envolvidos. MATERIAL E MÉTODO: A amostra consistiu de 306 universitários voluntários, com idade entre 19 e 35 anos, sendo usados como indicadores de saúde bucal os índices: Índice Periodontal Comunitário (CPI e Índice de Dentes Cariados, Perdidos e Obturados (CPO-D. Para processamento e análise dos dados, foi usado o programa SPSS versão 18.0. A classificação da condição periodontal foi dicotomizada em CPI 3. Realizou-se regressão logística bivariada e multivariada para analisar a associação entre a condição periodontal e as variáveis independentes. RESULTADO: A amostra consistiu de 51,3% de mulheres e 48,7% de homens, tendo a maioria renda menor do que 6 salários mínimos. Observou-se que 14,4% da amostra era livre de cárie. A pior condição periodontal foi encontrada no sextante 6 e 20,9% da amostra apresentou bolsas rasas em ao menos um sextante. Houve associação entre a condição periodontal e as variáveis: gênero, renda, nível de higiene bucal e uso do fio dental (p < 0,05; entretanto, não houve associação entre aquela e o CPO-D da amostra (p = 0,48. CONCLUSÃO: A amostra apresentou leve condição de doença periodontal, com ausência de bolsas periodontais profundas. Indivíduos do gênero feminino, de renda acima de 4 salários, com bom nível de higiene bucal e que usam o fio dental tiveram melhor condição de saúde periodontal.

A checklist has been included to assist the general dental practitioner identify individuals with undiagnosed diabetes. The literature indicates a similar incidence of periodontitis exists between well-controlled diabetics and non-diabetics. However, a greater incidence and severity of periodontitis is observed in both Type 1 and 2 long-term diabetics with poor metabolic control. There is an undeniable link between diabetes mellitus and periodontitis with complex interactions occurring between these diseases. A critical review of the literature fails to support the notion that periodontal therapy has a beneficial effect on the long-term control of diabetes. We have explored the associations between periodontitis and diabetes in the hope of providing the general dental practitioner with the knowledge to support the diabetic patient with the best possible dental care and advice.

    Periodontal disease is synonymous with the presence of periodontal pockets, and very often the clinical success of periodontal therapy is based on periodontal pocket depth reduction. Therefore, in the fields of periodontology and implant dentistry, significant research effort has been placed on the etiopathogenesis, diagnosis and treatment of periodontal/peri-implant disease and as a consequence on pocket pathology. In this volume of Periodontology 2000, the in-depth reviews include topics ranging from preclinical models, anatomy and structure of tissues, and molecular and bacterial components, to treatments of pockets around teeth and implants. These reviews aim to provide the readers with current and future perspectives on the different areas of research into the periodontal pocket. © 2017 John Wiley & Sons A/S.

    2014-06-01

    For decades, Aggregatibacter actinomycetemcomitans has been considered the most likely etiologic agent in aggressive periodontitis. Implementation of DNA-based microbiologic methodologies has considerably improved our understanding of the composition of subgingival biofilms, and advanced open-ended molecular techniques even allow for genome mapping of the whole bacterial spectrum in a sample and characterization of both the cultivable and not-yet-cultivable microbiota associated with periodontal health and disease. Currently, A. actinomycetemcomitans is regarded as a minor component of the resident oral microbiota and as an opportunistic pathogen in some individuals. Its specific JP2 clone, however, shows properties of a true exogenous pathogen and has an important role in the development of aggressive periodontitis in certain populations. Still, limited data exist on the impact of other microbes specifically in aggressive periodontitis. Despite a wide heterogeneity of bacteria, especially in subgingival samples collected from patients, bacteria of the red complex in particular, and those of the orange complex, are considered as potential pathogens in generalized aggressive periodontitis. These types of bacterial findings closely resemble those found for chronic periodontitis, representing a mixed polymicrobial infection without a clear association with any specific microorganism. In aggressive periodontitis, the role of novel and not-yet-cultivable bacteria has not yet been elucidated. There are geographic and ethnic differences in the carriage of periodontitis-associated microorganisms, and they need to be taken into account when comparing study reports on periodontal microbiology in different study populations. In the present review, we provide an overview on the colonization of potential periodontal pathogens in childhood and adolescence, and on specific microorganisms that have been suspected for their role in the initiation and progression of aggressive

    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.

    Full Text Available Tobacco use has been recognized to be a significant risk factor for the development and progression of periodontal disease. Its use is associated with increased pocket depths, loss of periodontal attachment, alveolar bone and a higher rate of tooth loss. Nicotine, a major component and most pharmacologically active agent in tobacco is likely to be a significant contributing factor for the exacerbation of periodontal diseases. Available literature suggests that nicotine affects gingival blood flow, cytokine production, neutrophil and other immune cell function; connective tissue turnover, which can be the possible mechanisms responsible for overall effects of tobacco on periodontal tissues. Inclusion of tobacco cessation as a part of periodontal therapy encourages dental professionals to become more active in tobacco cessation counseling. This will have far reaching positive effects on our patients′ oral and general health.

    Periodontal disease is considered to be an opportunistic infection as a result of interactions between the causative agents (dental plaque) and the host responses which may be modulated by genetic, environmental and acquired risk factors. Besides being a well-confirmed risk factor in a number of systemic diseases, tobacco smoking has also been associated with periodontal disease. Over the past 10-15 years, more and more scientific data on the impact of smoking on various aspects of periodontal disease and the underlying mechanisms has been published. The purpose of this review was to provide an overview of the available data in order to give practitioners a better understanding of the relationship between smoking and periodontal disease. Subsequently, they can use some of the information in treatment decisions and give advice to patients who are smokers suffering from periodontal disease.

Cross-sectional study carried out with students from the fourth grade of elementary school in the municipal capital of the southeastern region of Brazil. Food consumption and anthropometry were investigated by a questionnaire administered in school, while participation in the Bolsa Família program and other socio-economic information was obtained through a protocol applied to mothers/guardians. Statistical analysis included the Mann-Whitney test, the chi-squared test, and Poisson regression with robust variance, and the 5% significance level was adopted. There were 319 children evaluated; 56.4% were male, with a median of 9.4 (8.6-11.9) years, and 37.0% were beneficiaries of Bolsa Família program. Between the two groups, there was high prevalence of regular soda consumption (34.3%), artificial juice (49.5%), and sweets (40.3%), while only 54.3% and 51.7% consumed fruits and vegetables regularly, respectively. Among participants of Bolsa Família program, a prevalence 1.24 times higher in the regular consumption of soft drinks (95% CI: 1.10-1.39) was identified compared to non-beneficiaries. The prevalence of overweight was higher in the sample (32.9%), with no difference according to participation in the program. The study found increased consumption of soft drinks among BFP participants. The high rate of overweight and poor eating habits denote the need to develop actions to promote healthy eating, especially for the beneficiaries of the Bolsa Família program, to promote improvements in nutritional status and prevent chronic diseases throughout life.

    Full Text Available O Programa Bolsa Família (PBF é um programa de transferência condicionada de renda que vem sendo implementado no Brasil desde 2003 e atinge hoje milhões de famílias, tendo trazido inovações importantes tanto no desenho do programa como em sua gestão. Seus impactos sociais positivos têm sido amplamente discutidos pela literatura, contudo, o PBF também deve ser analisado sob o ponto de vista de inovações institucionais. Neste trabalho, partimos do neoinstitucionalismo histórico para discutir a gestão do PBF e algumas de suas inovações, tais como a criação do Cadastro Único e a gestão compartilhada e descentralizada.

    Conditional cash transfers are becoming the standard approach to reducing poverty levels; the Brazilian Bolsa Familia Program, in particular, is the largest program of this kind, and the evaluation of its impact allows for drawing some interesting conclusions, which may apply to other countries. In this paper, the lack of positive results in terms of both health status and modification of unhealthy habits is underlined. Among different causes, which are discussed here, the existence of barriers on the supply side appears as the most important limitation for obtaining better results. The positive impact of this program on both education and poverty reduction however, allows for predicting improvements in health status in the long run.

  5. Redistribution and development? the political economy of the Bolsa Família program

    Full Text Available The article offers a qualitative evaluation of Brazil's Bolsa Família (Family Grant or Family Stipend Program, viewing it from the perspective of an income redistribution and development policy. Analyzing the program's most striking institutional characteristics -- targeting the poorest and setting conditions such as school enrollment and immunization of the family's children -- the article identifies a major weakness in the program's political economy that could jeopardize its sustainability as a redistributive and development policy. The article suggests that policies with such characteristics in extremely unequal countries like Brazil can make budget limitations endogenous, thus hindering the achievement of the program's own objectives. Two alternative directions are briefly explored: conversion of the program into a hybrid policy, both targeted and universal, and emphasis on the provision of child education services.

    Full Text Available The paper examines the intergovernmental coordination of the Bolsa Família Program (PBF, given its goal to tackle poverty in acountry with deep social and regional inequality. It seeks to qualify the debate on the centralization of cash transfer programs in Brazil through the analysis of intergovernmental relations adopted under the three main dimensions of the PBF - cash transfer, monitoring of conditionalities and articulation of complementary programs - considering the federative implications derived from the intersectoral perspective that drives the Program. Two categories of challenges are highlighted. The first one relates to the need for greater investment in space and opportunities for intergovernmental negotiation, especially in the dimension of income transfer, which initially was characterized by centralization. In the second, the intergovernmental matter demands the organization of a coordinated national strategy for the articulation of complementary programs, suggesting greater involvement of states in the regional coordination of the Program

    Despite etiological differences between aggressive and chronic periodontitis, the treatment concept for aggressive periodontitis is largely similar to that for chronic periodontitis. The goal of treatment is to create a clinical condition that is conducive to retaining as many teeth as possible for as long as possible. When a diagnosis has been made and risk factors have been identified, active treatment is commenced. The initial phase of active treatment consists of mechanical debridement, either alone or supplemented with antimicrobial drugs. Scaling and root planing has been shown to be effective in improving clinical indices, but does not always guarantee long-term stability. Antimicrobials can play a significant role in controlling aggressive periodontitis. Few studies have been published on this subject for localized aggressive periodontitis, but generalized aggressive periodontitis has been subject to more scrutiny. Studies have demonstrated that systemic antibiotics as an adjuvant to scaling and root planing are more effective in controlling disease compared with scaling and root planing alone or with supplemental application of local antibiotics or antiseptics. It has also become apparent that antibiotics ought to be administered with, or just after, mechanical debridement. Several studies have shown that regimens of amoxicillin combined with metronidazole or regimens of clindamycin are the most effective and are preferable to regimens containing doxycycline. Azithromycin has been shown to be a valid alternative to the regimen of amoxicillin plus metronidazole. A limited number of studies have been published on surgical treatment in patients with aggressive periodontitis, but the studies available show that the effect can be comparable with the effect on patients with chronic periodontitis, provided that proper oral hygiene is maintained, a strict maintenance program is followed and modifiable risk factors are controlled.

    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.)

    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)

    Today's knowledge and studies show a firm correlation between osteoporosis and periodontitis, particularly in postmenopausal women. This review study deals with epidemiological and etiopathogenetic association between chronic periodontitis and an osteoporosis. A special emphasis is put on explanation of possible relations between a premature tooth loss and decrease of length and density of jaw bones, particularly their alveolar prolongations. The second part of the paper deals with principles of treatment in patients suffering of osteoporosis. Osteoporosis reduces density of jaw bones and decreases a number of teeth in jaws, but it does not affect other clinical signs and markers of periodontitis such as inflammation, bleeding and the depth of periodontal pockets and microbial plaque.

    2008-08-01

    Clinical signs and symptoms, as well as medical and dental history, are all considered in the clinical determination of gingival inflammation and periodontal disease severity. However, the "biologic systems model" highlights that the clinical presentation of periodontal disease is closely tied to the underlying biologic phenotype. We propose that the determination and integration of subject-level factors, microbial composition, systemic immune response, and gingival tissue inflammatory mediator responses will better reflect the biology of the biofilm-gingival interface in a specific patient and may provide insights on clinical management. Disease classifications and multivariable models further refine the biologic basis for the increasing severity of periodontal disease expression. As such, new classifications may better identify disease-susceptible and treatment-non-responsive individuals than current classifications that are heavily influenced by probing and attachment level measurements alone. New data also suggest that the clinical characteristics of some complex diseases, such as periodontal disease, are influenced by the genetic and epigenetic contributions to clinical phenotype. Although the genetic basis for periodontal disease is considered imperative for setting an inflammatory capacity for an individual and, thus, a threshold for severity, there is evidence to suggest an epigenetic component is involved as well. Many factors long associated with periodontitis, including bacterial accumulations, smoking, and diabetes, are known to produce strong epigenetic changes in tissue behavior. We propose that we are now able to rethink periodontal disease in terms of a biologic systems model that may help to establish more homogeneous diagnostic categories and can provide insight into the expected response to treatment.

    Poor women in the Bolsa Família program are accused of having more children in order to enroll or remain in the program. In an ethnographic study (2012-2014), we analyzed reports by five beneficiaries of the program and found exactly the opposite. The women reported that they had gone to public health services in Recife, Pernambuco State, Brazil, in hopes of avoiding more children, but that they had encountered various obstacles. Such barriers included difficulties in obtaining reversible contraception and restrictions in the supply of sterilization in these services, which increases the demand for cesarean sections. Their argument that they are beneficiaries of Bolsa Família aims to emphasize their poverty and increase the odds of obtaining sterilization (not always successful). Only two of the women had succeeded in obtaining sterilization, which they attributed to "luck" and "the grace of God" rather than as a right. The study's findings suggest that poor women increase their offspring not because they are enrolled in Bolsa Família, but due to the lack of access to reproductive rights.

    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

    Periodontal disease can significantly impact on the appearance of the anterior teeth. Prior to any definitive treatment, stabilization of the periodontal condition is a requirement. Treatment options can range from the placement of simple restorations, through orthodontic realignment, to the extraction and replacement of hopeless teeth. Each treatment plan must be individually tailored to the patient and level of periodontal disease, and must include provision for maintenance periodontal therapy. Periodontal diseases may compromise the prognosis of anterior teeth. Management is challenging and clinicians should take into consideration the short and long-term survival in treatment planning.

    Assessment of periodontal conditions in epidemiologic studies usually requires a clinical examination, which is resource-intensive. We investigated the ability of serum immunoglobulin G (IgG) antibodies to periodontal bacteria to reflect clinical periodontal status. We used checkerboard immunoblotting to assess serum IgG levels to 19 species, including established/putative periodontal pathogens and non-pathogenic bacteria, in 5,747 dentate adults aged > or = 40 years who participated in the third National Health and Nutrition Examination Survey between 1988 and 1994. Three earlier described alternative definitions of periodontitis were used, based on specific combinations of probing depth and attachment level values. Optimized elevated titer thresholds and corresponding sensitivities and specificities were calculated for each definition. Titers significantly associated with periodontitis were identified in univariable and multivariable logistic regression models. Parsimonious models were subsequently developed using age, gender, race/ethnicity, education, smoking, and diagnosed diabetes. In unadjusted models, high titers to Porphyromonas gingivalis were most strongly associated with periodontitis across all definitions (odds ratio, 2.07 to 2.74; P periodontitis, whereas high Eubacterium nodatum titers were associated with periodontal health in two of three definitions. Receiver operating characteristic curves for the parsimonious multivariable models showed that the area under the curve ranged between 0.72 and 0.78. Serum IgG titers to selected periodontal species, combined with demographic and behavioral characteristics, resulted in a moderately accurate classification of periodontal status in epidemiologic studies. The external validity of these findings must be examined further.

    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.

    Aim The purpose of the present study was to assess the extent to which the three periodontitis case definition systems proposed by van der Velden, Tonetti & Claffey and Page & Eke identify the same cases in a population of never-treated adults with limited tradition for oral hygiene procedures...... of the concomitant presence of CAL and BOP at the site level. Results The case definitions by Tonetti & Claffey and by Page & Eke yielded similar results, which were also quite similar to the results of simply identifying a case of periodontitis as a person having at least one site showing both CAL ≥ 4 mm and BOP....... Conclusions The results indicate that it should be feasible for the periodontal community to reach an agreement over the distinction between a case and a non-case. The classification system proposed by van der Velden is better suited for providing clinicians with a clear image of the case....

    The main nutritional deficiencies during childhood, namely anemia and malnutrition, are predominantly related to socio-economic factors. Thus, as the Bolsa Família Program (BFP) is the main policy to combat poverty, it is expected that it will have an impact on child nutrition. The aim was to analyze the differences in the nutritional situation of children registered with the BFP of a municipality located in Zona da Mata of Minas Gerais state. 446 children aged between 6 and 84 months were evaluated, of which 262 were non-beneficiaries and 184 were beneficiaries. Nutritional evaluation included analysis of weight and height parameters through weight/age, weight/height, height/age and Body Mass Index/age indexes and hemoglobin levels, using the Hemocue. The prevalence of anemia, short stature and obesity were 22.6, 6.3 and 5.2%, respectively, and there were no statistical differences between beneficiaries and non-beneficiaries. The beneficiary group initially had worse socio-economic conditions, but with the BFP it managed to financially match the non-beneficiary group. It is possible that the similarity between the two groups, also in the nutritional status, can be attributed to the program benefits, due to the financial funding as well as to the nutritional monitoring required as a condition of the program.

    Full Text Available Today, policies of combat to poverty prioritize women as owners in programs of income transference, among them, Bolsa Família Program. Considering that women empowerment is influenced by this social policy, this research aimed to identify the dimensions of the process of empowerment achieved by riparian women, beneficiary of the program. The research was performed at Combú Island, Belém do Pará. Four riparian mothers took part in the study. For data collection, the Sociodemographic Inventory and semi structured interviews were used. As procedure of organization of information, content analysis was used. The categories, which appeared from the beneficiary perceptions were adapted from literature and defined as economic, family, social and psychological empowerment. The results showed that after the entrance in BFP the notion of a owned income and bigger control of resources were obtained by a parcel of the participants, providing a partial economic empowerment. The befit increased the purchase power, and gave to these women grater management over family decision-making. The ownership of the program’s card made them to feel benefited when following-up children, providing social visibility to these mothers, when not depending completely of the husbands’ intermediation. Lastly, the benefit generated in the participants a feeling of stability, for having money, security for the family monthly needs. The empowerment that riparian women achieved shows that they passed to interfere in the dynamics and providing of the family before the lack or not of their husbands’ income.

    Full Text Available Income transfer programmes are common in various countries and play an important role in combating poverty. This article presents a review of the results of the Bolsa Família (Family Grant Programme, implemented in Brazil by the government of Lula da Silva in 2004. Over the last seven years many evaluations of the programme have been conducted, allowing an overview of its results and its strong and weak points to be mapped. Five central aspects relating to the programme are discussed in article five: (1 programme access, (2 hunger fighting results, (3 programme financial impacts, (4 conditioning factors of education and health, (5 supplementary programs and social mobility. The results of scientific research were presented for each of these aspects, and any of these believed to be convergent or divergent were discussed. As a general result it was concluded that the programme has generated significant results for the country, but there are still some issues that need to be reviewed, such as conditioning factors and the integrated management of the programme.

    This study evaluated the quality of diet of the population receiving the Bolsa Familia Program in Curitiba, state of Parana, Brazil. It was a population-based cross-sectional study, conducted from July 2006 to July 2007. 747 beneficiaries were interviewed from 19 years of age, of both genders. A 24 hour-recall was implemented in order to assess the quality of the diet and the Healthy Eating Index (HEI) was used as a parameter for the classification of the group in consumption levels. Descriptive statistics were used to describe the diet quality of the studied population. Wald test and ANOVA test were performed to compare the means of the index according to the socio-economic variables, considering a significance level of 5%. The sample comprised 91.4% of women and 8.6% of men. The average age of the population was 36.4 ± 13.3 years, with 75% having completed elementary school. The mean HEI was 51 points, which features a diet that needs improvement. The population has a monotonous diet with an adequate intake of legumes, but low for fruits, vegetables and dairy products. Comparing the categories of diet quality of individuals, all components, except sodium, showed statistically different median score (p < 0.01). Studies that evaluate the quality of the diet are essential to support the implementation of nutrition education programs targeted to the core of the problem in the populations studied.

    Periodontal disease has been associated with an increased risk of cardiovascular events. The purpose of our study was to investigate whether a correlation between periodontitis and chronic heart failure exists, as well as the nature of the underlying cause. We enrolled 71 patients (mean age, 54 ± 13 yr; 56 men) who had stable chronic heart failure; all underwent complete cardiologic and dental evaluations. The periodontal screening index was used to quantify the degree of periodontal disease. We compared the findings to those in the general population with use of data from the 4th German Dental Health Survey. Gingivitis, moderate periodontitis, and severe periodontitis were present in 17 (24%), 17 (24%), and 37 (52%) patients, respectively. Severe periodontitis was more prevalent among chronic heart failure patients than in the general population. In contrast, moderate periodontitis was more prevalent in the general population (P periodontal disease was not associated with the cause of chronic heart failure or the severity of heart failure symptoms. Six-minute walking distance was the only independent predictor of severe periodontitis. Periodontal disease is highly prevalent in chronic heart failure patients regardless of the cause of heart failure. Prospective trials are warranted to clarify the causal relationship between both diseases.

    Cochrane Library, Ovid, Medline, Embase and LILACS were searched using no language restrictions and included information up to July 2014. Bibliographic references of included articles and related review articles were hand searched. On-line hand searching of recent issues of key periodontal journals was performed (Journal of Clinical Periodontology, Journal of Dental Research, Journal of Periodontal Research, Journal of Periodontology, Oral Health and Preventive Dentistry). Prospective and retrospective cohort studies were used for answering the question of prediction since there were no randomised controlled trials on this topic. Risk of bias was assessed using the validated Newcastle-Ottawa quality assessment scale for non-randomised studies. Cross-sectional studies were included in the summary of currently reported risk assessment tools but not for risk of progression of disease, due to the inability to properly assess bias in these types of studies. Titles and abstracts were scanned by two reviewers independently.Full reports were obtained for those articles meeting inclusion criteria or those with insufficient information in the title to make a decision. Any published risk assessment tool was considered. The tool was defined to include any composite measure of patient-level risk directed towards determining the probability for further disease progression in adults with periodontitis. Periodontitis was defined to include both chronic and aggressive forms in the adult population. Outcomes included changes in attachment levels and/or deepening of periodontal pockets in millimeters in study populations undergoing supportive periodontal therapy. Data extraction was performed independently and in collaboration by two reviewers; completed evidence tables were reviewed by three reviewers. Studies were each given a descriptive summary to assess the quantity of data as well as further assessment of study variations within study characteristics. This also allowed for

  1. Nonsurgical periodontal therapy.

    Regular home care by the patient in addition to professional removal of subgingival plaque is generally very effective in controlling most inflammatory periodontal diseases. When disease does recur, despite frequent recall, it can usually be attributed to lack of sufficient supragingival and subgingival plaque control or to other risk factors that influence host response, such as diabetes or smoking. Causative factors contributing to recurrent disease include deep inaccessible pockets, overhangs, poor crown margins and plaque-retentive calculus. In most cases, simply performing a thorough periodontal debridement under local anesthesia will stop disease progression and result in improvement in the clinical signs and symptoms of active disease. If however, clinical signs of disease activity persist following thorough mechanical therapy, such as increased pocket depths, loss of attachment and bleeding on probing, other pharmacotherapeutic therapies should be considered. Augmenting scaling and root planing or maintenance visits with adjunctive chemotherapeutic agents for controlling plaque and gingivitis could be as simple as placing the patient on an antimicrobial mouthrinse and/or toothpaste with agents such as fluorides, chlorhexidine or triclosan, to name a few. Since supragingival plaque reappears within hours or days after its removal, it is important that patients have access to effective alternative chemotherapeutic products that could help them achieve adequate supragingival plaque control. Recent studies, for example, have documented the positive effect of triclosan toothpaste on the long-term maintenance of both gingivitis and periodontitis patients. Daily irrigation with a powered irrigation device, with or without an antimicrobial agent, is also useful for decreasing the inflammation associated with gingivitis and periodontitis. Clinically significant changes in probing depths and attachment levels are not usually expected with irrigation alone. Recent

    Full Text Available Resumen Las enfermedades periodontales son un significativo problema mundial a nivel de salud humana. Décadas de investigaciones, evidencian que en la mayoría de los casos la periodontitis crónica es la más común, caracterizada por ser de evolución lenta, con formación de bolsas periodontales, posterior reabsorción del hueso alveolar, pérdida y destrucción de piezas dentarias y tejido óseo. Si bien se reconoce el origen multifactorial en el desarrollo de la periodontitis, es relevante la participación de la microbiota subgingival en la etiología de la enfermedad periodontal. Algunas de las especies bacterianas patógenas que han sido asociadas con el desarrollo de la enfermedad periodontal son Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia, Fusobacterium nucleatum, entre otras. En este estudio, nos propusimos investigar cuáles de éstas cinco especies estaban presentes en las bolsas periodontales de 51 pacientes uruguayos con periodontitis crónica. Para alcanzar éste objetivo se utilizó una técnica convencional microbiológica y metagenómica (multiplex-PCR. Los resultados de la técnica convencional microbiológica evidenciaron la presencia de A. actinomycetemcomitans (33% y de bacterias negras pigmentadas anaerobias (100% en las muestras. De los resultados obtenidos en la multiplex-PCR, se demostró que las especies de mayor prevalencia fueron F. nucleatum (100%, T. forsythia (92% y P. gingivalis (88%.

    There has been increasing attention paid in recent years to the possibility that oral bacterial infection, particularly periodontal disease may influence the initiation and or progression of systemic diseases. These studies confirm the observation that heart disease is the most commonly found systemic condition in patients with periodontal disease. Moreover, the literature has also highlighted substantial evidence indicating the presence of Gram-negative periodontal pathogens in atheromatous plaques. This study intends to investigate the possible association between periodontal health and coronary artery disease by evaluating periodontal status, association between the periodontal plaque and coronary atheromatous plaques for presence of micro-organisms such as, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, and Tannerella forsythia. A case-control study was designed with seven patients who had undergone coronary endarterectomy for cardiovascular disease and 28 controls. The periodontal examination for cases was performed 1 day before vascular surgery and the controls were clinically examined. The atheromatous plaque sample collected during endarterectomy and the intraoral plaque samples were subjected to polymerase chain reaction for identification of A. actinomycetemcomitans, P. gingivalis, P. intermedia and T. forsythia. The presence of periodontal bacteria DNA in coronary atheromatous plaques and sub-gingival plaque samples of the same patients was confirmed by this study. CONCLUSION A correlation was established between putative bacteria contributing to atheromatous plaques and species associated with periodontal disease. One particularly important study to be carried out is the investigation of a possible clinically meaningful reduction in coronary heart disease resulting from the prevention or treatment of periodontal disease.

  4. PERIODONTAL DISEASE: LITERATURE REVIEW

    Directory of Open Access Journals (Sweden)

    J. D. Baia

    2017-10-01

    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.

  5. Necrotizing ulcerative periodontitis.

    Science.gov (United States)

    Novak, M J

    1999-12-01

    In patients with no known systemic disease or immune dysfunction, necrotizing periodontitis (NUP) appears to share many of the clinical and etiologic characteristics of necrotizing ulcerative gingivitis (NUG) except that patients with NUP demonstrate loss of clinical attachment and alveolar bone at affected sites. In these patients, NUP may be a sequela of a single or multiple episodes of NUG or may be the result of the occurrence of necrotizing disease at a previously periodontitis-affected site. The existence of immune dysfunction may predispose patients to NUG and NUP, especially when associated with an infection of microorganisms frequently associated with periodontal disease such as Treponema and Selenomonas species, Fuscobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. The role of immune dysfunction is exemplified by the occasionally aggressive nature of necrotic forms of periodontal disease seen in patients with HIV infection or malnutrition, both of which may impact host defenses. Clinical studies of HIV-infected patients have shown that patients with NUP are 20.8 times more likely to have CD4+ cell counts below 200 cells/mm3. However, these same studies have demonstrated that most patients with CD4+ cell counts below 200 cells/mm do not have NUP, suggesting that other factors, in addition to immunocompromisation, are involved. Further studies are needed to define the complex interactions between the microbial, or viral, etiology of necrotic lesions and the immunocompromised host. It is, therefore, recommended that NUG and NUP be classified together under the grouping of necrotizing periodontal diseases based on their clinical characteristics.

    Full Text Available ABSTRACT OBJECTIVE To describe the focalization and coverage of Bolsa Família Program among the families of children who are part of the 2004 Pelotas birth cohort (2004 cohort. METHODS The data used derives from the integration of information from the 2004 cohort and the Cadastro Único para Programas Sociais do Governo Federal (CadÚnico – Register for Social Programs of the Federal Government, in the 2004-2010 period. We estimated the program coverage (percentage of eligible people who receive the benefit and its focus (proportion of eligible people among the beneficiaries. We used two criteria to define eligibility: the per capita household income reported in the cohort follow-ups and belonging to the 20% poorest families according to the National Economic Indicator (IEN, an asset index. RESULTS Between 2004 and 2010, the proportion of families in the cohort that received the benefit increased from 11% to 34%. We observed an increase in all wealth quintiles. In 2010, by income and wealth quintiles (IEN, 62%-72% of the families were beneficiaries among the 20% poorest people, 2%-5% among the 20% richest people, and about 30% of families of the intermediate quintile. According to household income (minus the benefit 29% of families were eligible in 2004 and 16% in 2010. By the same criteria, the coverage of the program increased from 43% in 2004 to 71% in 2010. In the same period, by the wealth criterion (IEN, coverage increased from 29% to 63%. The focalization of the program decreased from 78% in 2004 to 32% in 2010 according to income, and remained constant (37% according to the IEN. CONCLUSIONS Among the families of the 2004 cohort, there was a significant increase in the program coverage, from its inception until 2010, when it was near 70%. The focus of the program was below 40% in 2010, indicating that more than half of the beneficiaries did not belong to the target population.

    Chronic gingivitis and periodontitis are common inflammatory conditions of the periodontal tissues. Given the ‘right’ concurrence of risk factors, a person with periodontitis can experience significant destruction of tooth-supporting bone, ultimately resulting in tooth loss. Poorly controlled diabetes is an important risk factor for periodontitis, and gingivitis and periodontitis are sometimes the first sign that a patient has diabetes. As severe periodontitis can lead to the loss of teeth, i...

    Periodontal disease is characterized by the destruction of tooth supporting tissues. Regeneration of periodontal tissues using ex vivo expanded cells has been introduced and studied, although appropriate methodology has not yet been established. We developed a novel cell transplant method for periodontal regeneration using periodontal ligament stem cell (PDLSC)-transferred amniotic membrane (PDLSC-amnion). The aim of this study was to investigate the regenerative potential of PDLSC-amnion in a rat periodontal defect model. Cultured PDLSCs were transferred onto amniotic membranes using a glass substrate treated with polyethylene glycol and photolithography. The properties of PDLSCs were investigated by flow cytometry and in vitro differentiation. PDLSC-amnion was transplanted into surgically created periodontal defects in rat maxillary molars. Periodontal regeneration was evaluated by microcomputed tomography (micro-CT) and histological analysis. PDLSCs showed mesenchymal stem cell-like characteristics such as cell surface marker expression (CD90, CD44, CD73, CD105, CD146, and STRO-1) and trilineage differentiation ability (i.e., into osteoblasts, adipocytes, and chondrocytes). PDLSC-amnion exhibited a single layer of PDLSCs on the amniotic membrane and stability of the sheet even with movement and deformation caused by surgical instruments. We observed that the PDLSC-amnion enhanced periodontal tissue regeneration as determined by micro-CT and histology by 4 weeks after transplantation. These data suggest that PDLSC-amnion has therapeutic potential as a novel cell-based regenerative periodontal therapy. PMID:24032400

    The association between osteoporosis and jawbones remains an argument of debate. Both osteoporosis and periodontal diseases are bone resorptive diseases; it has been hypothesized that osteoporosis could be a risk factor for the progression of periodontal disease and vice versa. Hypothetical models linking the two conditions exist: in particular, it is supposed that the osteoporosis-related bone mass density reduction may accelerate alveolar bone resorption caused by periodontitis, resulting i...

  20. Efficiency of nonsurgical periodontal therapy in moderate chronic periodontitis.

    Science.gov (United States)

    Mlachkova, Antoaneta M; Popova, Christina L

    2014-01-01

    Chronic periodontitis is defined as an inflammatory disease of the supporting tissues of teeth caused by microorganisms in the dental biofilm, resulting in progressive destruction of the periodontal ligament and alveolar bone with pocket formation and gingival recession. Treatment of chronic periodontitis aims at arresting the inflammation and stopping the loss of attachment by removal and control of the supra- and subgingival biofilm and establishing a local environment and microflora compatible with periodontal health. The AIM of this study was to evaluate the effectiveness of non-surgical therapy (scaling and root planning) in the treatment of moderate chronic periodontitis. The study included 30 patients aged between 33 and 75 years, of which 46.7% women and 53.3% men, diagnosed with moderate and, at some sites, severe periodontitis. They were treated with non-surgical periodontal therapy methods (scaling and root planning and curettage if indicated). Additionally, chemical plaque control with rinse water containing chlorhexidine was applied. The diagnostic and reassessment procedures included measuring the periodontal indices of 601 periodontal units before and after the therapy. The indices measured were the papillary bleeding index (PBI), the hygiene index (HI), the probing pocket depth (PPD) and the clinical attachment level (CAL). Significant reduction of plaque and gingival inflammation was found in all treated patients; we also found a statistically significant reduction of periodontal pockets with clinically measured depth 5 mm did not show statistically significant lower incidence rates probably due to the initially small percentage of deep pockets in the patients studied. There was a statistically significant reduction of all sites with attachment loss, the highest significance found at sites where the attachment loss was greater than 5 mm. The results of the study suggest that nonsurgical periodontal therapy is effective in managing the moderate

    2014-09-01

    Full Text Available Atherosclerotic disease (AD is one of the most important causes of morbidity and mortality in the world. It expresses inflammatory markers such as C-reactive protein (CRP and can provoke arterial wall thickening, which can be evaluated using Doppler ultrasound. Risk factors associated with AD include diabetes mellitus, systemic arterial hypertension, dyslipidemia and smoking. More recently, periodontal disease (PD has been identified as a factor related to AD. Periodontal disease has a high prevalence in the global population and the inflammatory process and bacterial activity at the periodontium appear to increase the risk of AD. Encouraging good oral hygiene can reduce expression of inflammatory markers of AD. A review of literature on PD, AD and inflammatory markers and the interrelationships between the two diseases was conducted using data published in articles indexed on the PUBMED, SCIELO and BIREME databases.

    2013-05-01

    Concrescence is a developmental anomaly of dental hard tissues. It is a condition showing union of adjacent teeth by cementum. The concrescence leads to a loss of gingival architecture leading to the development of funnels, which may cause plaque accumulation thus, resulting in periodontal tissue destruction. There is a slight predilection for the mandible especially in the premolar area followed by the molar and anterior regions. Awareness of these developmental disturbances with proper diagnosis and treatment is very essential because it can compromise the periodontal attachment and can lead to the tooth loss. This article highlights the presence of a concrescence between mandibular second molar and the supernumerary fused teeth with their clinical and radiographic findings, along with its management.

    2002-05-01

    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 which includes generalized or localized prepubertal periodontitis and juvenile periodontitis) and periodontal diseases associated with systemic disorders. The best approach to managing periodontal diseases is prevention, followed by early detection and treatment. This paper reviews the current literature concerning the most common periodontal diseases affecting children: chronic gingivitis (or dental plaque-induced gingival diseases) and early onset periodontitis (or aggressive periodontitis), including prepubertal and juvenile periodontitis. In addition, systemic diseases that affect the periodontium and oral lesions commonly found in young children are addressed. The prevalence, diagnostic characteristics, microbiology, host-related factors, and therapeutic management of each of these disease entities are thoroughly discussed.

    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.

    Full Text Available Background: There has been increasing attention paid in recent years to the possibility that oral bacterial infection, particularly periodontal disease may influence the initiation and or progression of systemic diseases. These studies confirm the observation that heart disease is the most commonly found systemic condition in patients with periodontal disease. Moreover, the literature has also highlighted substantial evidence indicating the presence of Gram-negative periodontal pathogens in atheromatous plaques. Aim: This study intends to investigate the possible association between periodontal health and coronary artery disease by evaluating periodontal status, association between the periodontal plaque and coronary atheromatous plaques for presence of micro-organisms such as, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, and Tannerella forsythia. Materials and methods: A case-control study was designed with seven patients who had undergone coronary endarterectomy for cardiovascular disease and 28 controls. The periodontal examination for cases was performed 1 day before vascular surgery and the controls were clinically examined. The atheromatous plaque sample collected during endarterectomy and the intraoral plaque samples were subjected to polymerase chain reaction for identification of A. actinomycetemcomitans, P. gingivalis, P. intermedia and T. forsythia. Results: The presence of periodontal bacteria DNA in coronary atheromatous plaques and sub-gingival plaque samples of the same patients was confirmed by this study. CONCLUSION A correlation was established between putative bacteria contributing to atheromatous plaques and species associated with periodontal disease. One particularly important study to be carried out is the investigation of a possible clinically meaningful reduction in coronary heart disease resulting from the prevention or treatment of periodontal disease.

    Full Text Available As bolsas guturais são divertículos da tuba auditiva, divididas em compartimentos lateral e medial, possuindo função termorregulatória. Suas mais frequentes afecções são empiema, micose e timpanismo. O empiema é o que ocorre com maior frequência, tendo como principal agente causador o Streptococcus equi. Animais acometidos apresentam secreção nasal e quando crônico, há espessamento deste material, resultando em concreções duras, os condróides. O objetivo deste trabalho é relatar a utilização do acesso cirúrgico através do triângulo de Viborg, fenestração videoendoscópica do septo mediano e retirada de condróides da bolsa gutural. Relata-se o caso de um equino que apresentava secreção nasal, apatia e anorexia. Através de endoscopia observou-se secreção purulenta principalmente na bolsa direita, caracterizando empiema. Realizou-se coleta deste material para realização de exame microbiológico. Foi instituído o tratamento clínico, porém sem resultados satisfatórios. Realizou-se, sob anestesia geral, a fenestração do septo mediano e acesso à bolsa pelo triângulo de Viborg no lado esquerdo, com implantação de sonda de Foley até a entrada da bolsa direita. Sem sucesso no tratamento pós-cirúrgico foi realizada nova endoscopia onde verificou-se a presença de condróides os quais foram retirados por novo procedimento cirúrgico, desta vez pelo lado direito. Conclui-se com este relato que a técnica de acesso à bolsa gutural pelo triângulo de Viborg mostra-se muito eficaz na remoção de condróides, que a fenestração do septo potencializa a limpeza diária das bolsas e que o exame endoscópico é a principal forma de diagnóstico do empiema, podendo este ser causado por Pseudomonas aeruginosa.

    Periodontal disease is one of the most common infectious diseases in adults and is characterized by the destruction of tooth-supporting tissues. Mesenchymal stem cells (MSCs) comprise the mesoderm-originating stem cell population, which has been studied and used for cell therapy. However, because of the lower rate of cell survival after MSC transplantation in various disease models, paracrine functions of MSCs have been receiving increased attention as a regenerative mechanism. The aim of this study was to investigate the regenerative potential of transplanted conditioned medium (CM) obtained from cultured periodontal ligament stem cells (PDLSCs), the adult stem cell population in tooth-supporting tissues, using a rat periodontal defect model. Cell-free CM was collected from PDLSCs and fibroblasts, using ultrafiltration and transplanted into surgically created periodontal defects. Protein content of CM was examined by antibody arrays. Formation of new periodontal tissues was analyzed using microcomputed tomography and histological sections. PDLSC-CM transplantation enhanced periodontal tissue regeneration in a concentration-dependent manner, whereas fibroblast-CM did not show any regenerative function. Proteomic analysis revealed that extracellular matrix proteins, enzymes, angiogenic factors, growth factors and cytokines were contained in PDLSC-CM. Furthermore, PDLSC-CM transplantation resulted in the decreased mRNA level of tumor necrosis factor-α (TNF-α) in healing periodontal tissues. In addition, we found that PDLSC-CM suppressed the mRNA level of TNF-α in the monocyte/macrophage cell line, RAW cells, stimulated with IFN-γ. Our findings suggested that PDLSC-CM enhanced periodontal regeneration by suppressing the inflammatory response through TNF-α production, and transplantation of PDLSC-CM could be a novel approach for periodontal regenerative therapy.

Utiliza-se o procedimento de propensity score matching para encontrar mães não atendidas pelo programa comparáveis às mães atendidas, a partir de três grupos de controle. Os resultados apontam a existência de um efeito-renda associado ao valor do benefício, uma vez que quanto maior a transferência recebida, menor o engajamento da mãe no mercado de trabalho. Entretanto, o efeito líquido de ser beneficiário do programa é positivo, indicando a existência de um efeito-substituição, provavelmente decorrente da redução da oferta de trabalho dos filhos, da maior disponibilidade de tempo das mães para trabalhar ou mesmo do estigma em participar do programa.This paper investigates the existence of a possible adverse incentive on the labor supply and weekly working hours of beneficiary mothers of the Bolsa Família Program. Three control groups are analyzed using propensity-score matching to compare non-beneficiary mothers to beneficiary mothers. The results show that there is a wealth effect related to the value of the benefits, given that the larger the benefit, the less active beneficiary mothers are in the labor market. Nonetheless, the net effect is positive, showing that there is a substitution effect due to a reduction in the children´s labor supply, a rise in the mother's available time, as well as decreasing the stigma.

    Bacterial etiology of periodontal disease is an established fact today. However, despite advances in the field of pharmacology with advent of newer and better antibiotics prevalence of the disease could not be abated. Moreover, unpredictable remissions and indefinite pattern in a single host force us to go back to the exact etiology of the disease. Present is a short review highlighting the role and plausible mechanisms by which viruses can affect the development of periodontal disease. This broadens our concept and will help establish a better treatment protocol for periodontal disease. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2015-01-01

    Periodontal disease is a high prevalent disease. In the United States 47.2% of adults ≥ 30 years old have been diagnosed with some type of periodontitis. Longitudinal studies have demonstrated a two-way relationship between diabetes and periodontitis, with more severe periodontal tissue destruction in diabetic patients and poorer glycemic control in diabetic subjects with periodontal disease. Periodontal treatment can be successful in diabetic patients. Short term effects of periodontal treatment are similar in diabetic patients and healthy population but, more recurrence of periodontal disease can be expected in no well controlled diabetic individuals. However, effects of periodontitis and its treatment on diabetes metabolic control are not clearly defined and results of the studies remain controversial. PMID:26185600

    Periodontitis is a biofilm-induced inflammatory disease affecting the periodontium with a high and even increasing prevalence in the German population. During recent years, there is emerging evidence for systemic effects of a periodontal infection, in particular in relation to diabetes and atherosclerosis. There is a bi-directional relationship between periodontitis and diabetes. Diabetes promotes the occurrence, the progression, and the severity of periodontitis. The periodontal infection complicates the glycemic control in diabetes, increases the risk of diabetes-associated complications and possibly even of its onset. As a consequence, the treatment of periodontal infections should become an integral part of the management of diabetes, whereas glycemic control is a prerequisite for successful periodontal therapy. Periodontal infections are considered as independent risk factor for atherosclerosis and their clinical sequelae, e.g., cerebro- and cardiovascular diseases. The positive association is only moderate, however remarkably consistent. Periodontal therapy can result in positive effects on subclinical markers of atherosclerosis.

    2009-12-01

    Smoking is an independent risk factor for periodontal disease and tooth loss. Smoking impairs inflammatory and immune responses to periodontal pathogens, and exerts both systemic and local effects. Periodontal disease is increased both in prevalence and severity in smokers. Smoking is a predisposing factor to acute necrotizing ulcerative gingivitis and is associated with an increased rate of periodontal disease in terms of pocket formation and attachment loss, as well as alveolar bone loss. Cigar, pipe, water-pipe and cannabis smoking have similar adverse effects on periodontal health as cigarette smoking. Passive smoking is also an independent periodontal disease risk factor. Smokeless tobacco is associated with localized periodontal disease. Smokers respond less favourably to both non-surgical and surgical treatments and have higher failure rates and complications following dental implantation. Smoking cessation may halt the disease progression and improve the outcome of periodontal treatment. Smoking cessation counselling should be an integral part of periodontal therapy and prevention.

    Full Text Available Obesity is associated with an increased risk for developing characteristic features of metabolic syndrome, including hypertension, type 2 diabetes, and dyslipidemia. Interestingly, chronic exposure to periodontal pathogens’ endotoxin and increased cytokine production have been proposed to enhance the risk for causing type 2 diabetes and cardiovascular complications. Obesity has also recently been reported to be associated with periodontitis. Obesity induces macrophage accumulation in adipose tissue, promotes chronic low-grade inflammation, and increases adipokines derived from adipocytes. In this review, we summarize recent advances in understanding the roles of adipokines in chronic inflammatory states such as periodontitis and focus primarily on adiponectin, leptin, and resistin. Understanding the role of adipokines may help elucidate relationships among periodontitis, obesity, type 2 diabetes, and cardiovascular diseases.

    Aggressive periodontitis is a type of periodontitis with early onset and rapid progression and mostly affecting young adults who occupy a large percentage of orthodontic patients. The role of the orthodontist is important in screening the disease, making a provisional diagnosis, and referring it to a periodontist for immediate treatment. The orthodontist should be aware of the disease not only before starting the appliance therapy, but also during and after the active mechanotherapy. The orthodontic treatment plan, biomechanics, and appliance system may need to be modified to deal with the teeth having reduced periodontal support. With proper force application and oral hygiene maintenance, orthodontic tooth movement is possible without any deleterious effect in the tooth with reduced bone support. With proper motivation and interdisciplinary approach, orthodontic treatment is possible in patients with controlled aggressive periodontitis. PMID:28299350

    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. In conclusion there were increasing pocket depth and alveolar bone damage in smokers.

    Population projections predict an increasing number of dentate older people who will require assessment and treatment of periodontal disease. Studies show that healthy, older patients show no increased risk of periodontal disease progression compared to younger individuals, while periodontal treatment can be equally successful in the older age group. However, co-morbidity can impact negatively on both the periodontal tissues and the dentition. These effects range from a reduced ability to maintain adequate plaque control, to the use of drug and other therapies directly affecting the periodontal tissues and salivary flow. An individualized treatment plan is required for older patients, taking account of all factors impacting on the periodontal tissues.

    The two most prevalent and most investigated periodontal diseases are dental plaque-induced gingivitis and chronic periodontitis. The last 10 to 15 years have seen the emergence of several important new findings and concepts regarding the etiopathogenesis of periodontal diseases. These findings include the recognition of dental bacterial plaque as a biofilm, identification and characterization of genetic defects that predispose individuals to periodontitis, host-defense mechanisms implicated in periodontal tissue destruction, and the interaction of risk factors with host defenses and bacterial plaque. This article reviews current aspects of the etiology and pathogenesis of periodontal diseases.

    It is critical to understand the underlying host responses in aggressive periodontitis to provide a better appreciation of the risk and susceptibility to this disease. Such knowledge may elucidate the etiology and susceptibility to aggressive periodontitis and directly influence treatment decisions and aid diagnosis. This review is timely in that several widely held tenets are now considered unsupportable, namely the concept that Aggregatibacter actinomycetemycomitans is the key pathogen and that chemotactic defects in polymorphonuclear leukocytes are part of the etiopathology. This review also serves to put into context key elements of the host response that may be implicated in the genetic background of aggressive periodontitis. Furthermore, key molecules unique to the host response in aggressive periodontitis may have diagnostic utility and be used in chairside clinical activity tests or as population screening markers. It is becoming increasingly appreciated that the microbial etiology of aggressive periodontitis and the histopathology of this disease are more similar to than different from that of chronic periodontitis. An important therapeutic consideration from the lack of support for A. actinomycetemycomitans as a critical pathogen here is that the widely held belief that tetracycline had a role in aggressive periodontitis therapy is now not supported and that antibiotics such as those used effectively in chronic periodontitis (metronidazole and amoxicillin) are not contraindicated. Furthermore, A. actinomycetemycomitans-related molecules, such as cytolethal distending toxin and leukotoxin, are less likely to have utility as diagnosis agents or as therapeutic targets. © 2014 John Wiley & Sons A/S.

    Early diagnosis is necessary if the prevalence of periodontal disease is to be brought under control. For periodontal screening in dental practice we propose to employ the C.P.I.T.N. system, combined with examination of two or four dental bite-wing radiographs. Both of these procedures can be accurately applied in general dental practice conditions. The screening is not time consuming and can yield very important diagnostic data.

    Current periodontal disease taxonomies have limited utility for predicting disease progression and tooth loss; in fact, tooth loss itself can undermine precise person-level periodontal disease classifications. To overcome this limitation, the current group recently introduced a novel patient stratification system using latent class analyses of clinical parameters, including patterns of missing teeth. This investigation sought to determine the clinical utility of the Periodontal Profile Classes and Tooth Profile Classes (PPC/TPC) taxonomy for risk assessment, specifically for predicting periodontal disease progression and incident tooth loss. The analytic sample comprised 4,682 adult participants of two prospective cohort studies (Dental Atherosclerosis Risk in Communities Study and Piedmont Dental Study) with information on periodontal disease progression and incident tooth loss. The PPC/TPC taxonomy includes seven distinct PPCs (person-level disease pattern and severity) and seven TPCs (tooth-level disease). Logistic regression modeling was used to estimate relative risks (RR) and 95% confidence intervals (CI) for the association of these latent classes with disease progression and incident tooth loss, adjusting for examination center, race, sex, age, diabetes, and smoking. To obtain personalized outcome propensities, risk estimates associated with each participant's PPC and TPC were combined into person-level composite risk scores (Index of Periodontal Risk [IPR]). Individuals in two PPCs (PPC-G: Severe Disease and PPC-D: Tooth Loss) had the highest tooth loss risk (RR = 3.6; 95% CI = 2.6 to 5.0 and RR = 3.8; 95% CI = 2.9 to 5.1, respectively). PPC-G also had the highest risk for periodontitis progression (RR = 5.7; 95% CI = 2.2 to 14.7). Personalized IPR scores were positively associated with both periodontitis progression and tooth loss. These findings, upon additional validation, suggest that the periodontal/tooth profile classes and the derived

Obese individuals have an increased risk of periodontitis, and elevated circulating levels of nicotinamide phosphoribosyltransferase (NAMPT) may be a pathomechanistic link between both diseases. Recently, increased levels of NAMPT have also been found in patients with periodontitis, irrespective of the presence of obesity. This in vitro study sought to examine the effects of NAMPT on the regenerative capacity of human periodontal ligament (PDL) cells and, thereby, periodontal healing. PDL cells treated with enamel matrix derivative (EMD), which was used to mimic regenerative healing conditions in vitro, were grown in the presence and absence of NAMPT for up to 14 d. EMD stimulated significantly (P periodontal regeneration are counteracted by NAMPT. Enhanced levels of NAMPT, as found in obesity and periodontal inflammation, may compromise the regenerative capacity of PDL cells and, thereby, periodontal healing in the presence of EMD.

Unfortunately, its application in periodontics is not widely popularized. The objective of this article is to emphasize the application of microsurgical principles in various periodontal surgical procedures and to reinforce the incorporation of microscope into periodontal practice. The most recent periodontal journals were reviewed and a search of databases such as PubMed or Medline and Google Scholar was conducted for relevant material from published literature up to 2017. Medical Subject Headings words looked for were “periodontal microsurgery” and “minimally invasive periodontal surgery.” The available literature, specifically to periodontal surgical procedures was analyzed and compiled. The analysis indicates that incorporation of magnification in periodontal practice is associated with improved visual acuity, ergonomic benefits, decreased patient morbidity, rapid healing, and enhanced patient acceptance.

    Full Text Available Income transfer programmes are common in various countries and play an important role in combating poverty. This article presents a review of the results of the Bolsa Família (Family Grant Programme, implemented in Brazil by the government of Lula da Silva in 2004. Over the last seven years many evaluations of the programme have been conducted, allowing an overview of its results and its strong and weak points to be mapped. Five central aspects relating to the programme are discussed in article five: (1 programme access, (2 hunger fighting results, (3 programme financial impacts, (4 conditioning factors of education and health, (5 supplementary programs and social mobility. The results of scientific research were presented for each of these aspects, and any of these believed to be convergent or divergent were discussed. As a general result it was concluded that the programme has generated significant results for the country, but there are still some issues that need to be reviewed, such as conditioning factors and the integrated management of the programme.Les programmes de transfert de revenus sont courants dans plusieurs pays et jouent un rôle important dans la lutte contre la pauvreté.

    Full Text Available Relations between poor people and the government that creates the Programa Bolsa Familia at Brazil may be summarized in two dimensions: 1 favor direct relationships without the intervention of collective action and 2 are distant relations in terms of type of interaction and communication between the authorities and beneficiaries. While there are instances of formal social control, operation of the program makes minimal intermediation and highly institutional and civic organizations have little room to act and to represent the beneficiaries of Bolsa Familia in institutionalized interfaces. Direct links generate positive effect low levels of political patronage vote buying and coercion, but also generate unintended effects such as the lack of program operation, difficulty to defend themselves collectively by irregularities and create an active citizenry.

    Periodontal diseases are initiated by bacterial species living in polymicrobial biofilms at or below the gingival margin and progress largely as a result of the inflammation initiated by specific subgingival species. In the past few decades, efforts to understand the microbiota of periodontal diseases have led to an exponential increase in information about biofilms associated with periodontal health and disease. In fact, the oral microbiota is one of the best characterized microbiomes that colonize the human body. Despite this increased knowledge, one has to ask if our fundamental concepts of the etiology and pathogenesis of periodontal diseases have really changed. In this chapter we will review how our comprehension of the structure and function of the subgingival microbiota evolved over the years in search of lessons learned and unlearned in periodontal microbiology. More specifically, this review focuses on: 1) how the data obtained through molecular techniques has impacted our knowledge of the etiology of periodontal infections; 2) the potential role of viruses in the etiopathogenesis of periodontal diseases; 3) how concepts of microbial ecology have expanded our understanding of host microbial interactions that might lead to periodontal diseases; 4) the role of inflammation in the pathogenesis of periodontal diseases; and 5) the impact of these evolving concepts on treatment and preventive approaches to periodontal infections. We will conclude by reviewing how novel systems biology approaches promise to unravel new details of the pathogenesis of periodontal diseases and, hopefully, lead to a better understanding of periodontal disease mechanisms.

    The aim of this study is to determine whether periodontal health knowledge is associated with frequency of tooth brushing and periodontal treatment need. Four hundred and two subjects participated in the study. Data on sociodemographic variables (age, gender, marital status, income, and education), general health, smoking behaviour tooth cleaning habits and knowledge on periodontal health/disease were collected with a questionnaire. Periodontal treatment need was examined using the Community Periodontal Index of Treatment Needs (CPITN). According to the CPITN scores, the treatment needs were grouped as minimum (CPITN = 0), low-level (CPITN = 1-2), or high-level (CPITN = 3-4). Statistical differences were found between the frequency of tooth brushing and smoking status, marital status, periodontal health knowledge and periodontal treatment needs. Gender (females), place of residence (urban areas), education and periodontal health knowledge had positive relationship with tooth brushing frequency, while smoking and periodontal treatment need had negative relationship. When multivariate logistic regression analysis was applied, age, marriage and poor periodontal knowledge were associated with increased low-level periodontal treatment needs, and age, marriage and smoking were associated with increased high-level periodontal treatment need. In the limits of this study, we suggest that gender, smoking habits, marital status, place of residence, education and periodontal health knowledge are determining factors related to tooth brushing frequency. Periodontal knowledge and smoking are associated with periodontal treatment needs.

    Full Text Available ABSTRACT Objective: To assess the impact of the Bolsa Família Program on the energy and nutrient intakes of beneficiaries from the Brazilian Northeast and Southeast regions. Methods: The study used data from the 2008-2009 Pesquisa de Orçamento Famíliar, which assessed individual food intake on two nonconsecutive days of individuals aged more than 10 years. Based the personal information booklet, food intake values were transformed into nutritional values (energy and nutrients. Analysis of the impact measure was preceded by propensity score matching, a technique that matches some socioeconomic characteristics of beneficiaries and nonbeneficiaries. Once the score was calculated, the impact of the Bolsa Família Program was estimated by nearest neighbor matching. Results: The program increased energy and macronutrient intakes and decreased calcium and vitamin A, D, E, and C intakes of adolescent beneficiaries in both regions. Adult beneficiaries from the Southeast region increased their fiber, iron, and selenium intakes, and those from the Northeast region decreased their energy, lipid, added sugar, sodium, zinc, vitamin E, and pyridoxine intakes. Conclusion: The results show a positive impact of the program on the energy and macronutrient intakes, and a negative impact on the intakes of most study micronutrients, especially in adolescents, which reinforce the importance of implementing intersectoral actions to improve the nutritional quality of the Bolsa Família Program beneficiaries' diet.

    The association between osteoporosis and jawbones remains an argument of debate. Both osteoporosis and periodontal diseases are bone resorptive diseases; it has been hypothesized that osteoporosis could be a risk factor for the progression of periodontal disease and vice versa. Hypothetical models linking the two conditions exist: in particular, it is supposed that the osteoporosis-related bone mass density reduction may accelerate alveolar bone resorption caused by periodontitis, resulting in a facilitated periodontal bacteria invasion. Invading bacteria, in turn, may alter the normal homeostasis of bone tissue, increasing osteoclastic activity and reducing local and systemic bone density by both direct effects (release of toxins) and/or indirect mechanisms (release of inflammatory mediators). Current evidence provides conflicting results due to potential biases related to study design, samples size and endpoints. The aim of this article is to review and summarize the published literature on the associations between osteoporosis and different oral conditions such as bone loss in the jaws, periodontal diseases, and tooth loss. Further well-controlled studies are needed to better elucidate the inter-relationship between systemic and oral bone loss and to clarify whether dentists could usefully provide early warning for osteoporosis risk.

    Full Text Available This case report demonstrates an orthodontic method that offers short treatment time and the ability to simultaneously reshape and increase the buccolingual thickness of the supporting alveolar bone. A 23-year-old female with Angle′s Class I moderately to severely crowded malocclusion with periodontal pocket with 31 and reduced thickness of the buccal cortical plate of lower anteriors, requested shortened orthodontic treatment time. This surgery technique included buccal full-thickness flaps, selective partial decortication of the cortical plates, concomitant bone grafting/augmentation, and primary flap closure. Following the surgery, orthodontic adjustments were made approximately every 2 weeks. From bracketing to debracketing, the case was completed in approximately 7 months and 3 weeks. Posttreatment evaluation of patient revealed good results. Preexisting thin labial bony cortical plate with lower anteriors was covered. This finding suggests credence to the incorporation of the bone augmentation procedure into the corticotomy surgery because this made it possible to complete the orthodontic treatment with a more intact periodontium. The rapid expansive tooth movements with no significant apical root resorption may be attributed to the osteoclastic or catabolic phase of the regional acceleratory phenomenon.

    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.

    The validity of using pretreatment Periodontal Screening and Recording (PSR) index sextant scores to estimate periodontal access surgery needs is evaluated in patients with chronic periodontitis before and after completion of non-surgical periodontal therapy. In 110 adults, pretreatment probing data identified 486 sextants with PSR scores of 4 and 125 sextants with PSR scores of 3. Periodontal access surgery needs for all sextants were determined prior to treatment and after completion of non-surgical periodontal therapy for 213 sextants in 38 patients by two experienced periodontist examiners. PSR scores of 4 identified untreated sextants with periodontal access surgery needs significantly better than PSR scores of 3 (odds ratio = 27.8; P periodontal access surgery need continued to have surgical access needs after completion of non-surgical periodontal therapy. A higher percentage of sextants with PSR scores of 4 or 3 revealed periodontal access surgical needs when Class II or III furcation involvements and/or Grade II or III tooth mobility were also detected in the sextant than when these parameters were not detected. Pretreatment PSR index scores of 4 were a strong indicator of periodontal access surgery needs in untreated dentition sextants but markedly overestimated surgical access needs remaining after completion of non-surgical periodontal therapy. These findings raise questions about the usefulness of pretreatment PSR evaluations for estimating potential periodontal access surgery needs in patients to be initially treated with non-surgical periodontal therapy.

    The association between diabetes and periodontal diseases is well-established. Diabetes is a risk factor for periodontal disease, with diabetic patients exhibiting an increased prevalence, extent and severity of gingivitis and perio- dontitis compared to healthy adults. Several mechanisms involved in the pathogenesis of diabetes have also been associated with periodontal disease progression. It is recognized today that there is a bidirectional relationship between diabetes and periodontal disease, with recent research showing that periodontal disease may affect the metabolic control of diabetes in diabetic patients. In this review, we present the current knowledge of the interplay between periodontal diseases and diabetes through the evaluation of randomized control and longitudinal cohort studies published in the past 15 years. Current data support the conclusion that diabetic patients are at increased risk for periodontal diseases, and that patients with poorly controlled diabetes are at risk for severe periodontitis. This results in the destruction of oral connective tissue and generalized bone loss, leading ultimately to tooth loss. Although the effect of periodontal disease on glycemic control in type 1 diabetic patients is controversial, evidence does show a direct correlation between periodontal health and glycemic control in type 2 diabetic patients. Furthermore, several studies have demonstrated the beneficial effect of periodontal treatment on metabolic control of type 2 diabetic patients.

  3. Periodontitis and increase in circulating oxidative stress

    Full Text Available Reactive oxygen species (ROS are products of normal cellular metabolism. However, excessive production of ROS oxidizes DNA, lipids and proteins, inducing tissue damage. Studies have shown that periodontitis induces excessive ROS production in periodontal tissue. When periodontitis develops, ROS produced in the periodontal lesion diffuse into the blood stream, resulting in the oxidation of blood molecules (circulating oxidative stress. Such oxidation may be detrimental to systemic health. For instance, previous animal studies suggested that experimental periodontitis induces oxidative damage of the liver and descending aorta by increasing circulating oxidative stress. In addition, it has been revealed that clinical parameters in chronic periodontitis patients showed a significant improvement 2 months after periodontal treatment, which was accompanied by a significant reduction of reactive oxygen metabolites in plasma. Improvement of periodontitis by periodontal treatment could reduce the occurrence of circulating oxidative stress. Furthermore, recent studies indicate that the increase in circulating oxidative stress following diabetes mellitus and inappropriate nutrition damages periodontal tissues. In such cases, therapeutic approaches to systemic oxidative stress might be necessary to improve periodontal health.

    No information exists on periodontitis-associated subgingival microbiota from Turkey. We determined the occurrence, interspecies relationships, and clonal characteristics for a group of periodontal bacteria in a Turkish study population. Subgingival microbial samples were obtained from patients with localized (LAgP, N = 18) or generalized (GAgP, N = 17) types of aggressive periodontitis, generalized chronic periodontitis (GCP, N = 14), and non-periodontitis subjects (N = 20). Culture methods were used to recover 6 periodontal bacterial species and yeasts, and a polymerase chain reaction technique was used to detect Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis. Intraspecies characterization of A. actinomycetemcomitans was carried out by serotyping and genotyping. All species, except for Micromonas micros (formerly Peptostreptococcus micros) occurred more frequently (P periodontitis than non-periodontitis subjects. Detection frequencies for Tannerella forsythensis (formerly Bacteroides forsythus) and Campylobacter rectus differed among the periodontitis subgroups; the lowest frequency occurred in LAgP. The mean proportions of A. actinomycetemcomitans, P. gingivalis, and C. rectus were higher (P periodontitis subjects. Significant positive associations were seen between 7 of the 22 possible combinations (P periodontitis. However, A. actinomycetemcomitans was not overrepresented in LAgP, and the serotype distribution resembled that reported from the East.

    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.

    Full Text Available Periodontitis is a chronic inflammatory process which affects the tooth - supporting structures of the teeth. The disease is initiated by subgingival periopathogenic bacteria in susceptible periodontal sites. The host immune response towards periodontal pathogens helps to sustain periodontal disease and eventual alveolar bone loss. Although scaling and root planing is the standard treatment modality for periodontitis, it suffers from several drawbacks such as the inability to reach the base of deep pockets and doesn’t arrest migration of periodontal pathogens from other sites in the oral cavity. In order to overcome the limitations of scaling and root planning, adjunctive chemotherapeutics and host modulatory agents to the treatment are used. These therapeutic agents show substantial beneficial effects when compared to scaling and root planning alone. This review will cover an update on chemotherapeutic and past and future host immune modulatory agents used adjunctively to treat and manage periodontal diseases.

    To investigate the correlation between postmenopausal osteoporosis (PMO) and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-)6, the receptor activator of nuclear factor- κB ligand (RANKL), and osteoprotegerin (OPG) and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues.

    This study evaluates the accuracy of periodontitis prevalence determined by the National Health and Nutrition Examination Survey (NHANES) partial-mouth periodontal examination protocols. True periodontitis prevalence was determined in a new convenience sample of 454 adults ≥ 35 years old, by a full-mouth "gold standard" periodontal examination. This actual prevalence was compared with prevalence resulting from analysis of the data according to the protocols of NHANES III and NHANES 2001-2004, respectively. Both NHANES protocols substantially underestimated the prevalence of periodontitis by 50% or more, depending on the periodontitis case definition used, and thus performed below threshold levels for moderate-to-high levels of validity for surveillance. Adding measurements from lingual or interproximal sites to the NHANES 2001-2004 protocol did not improve the accuracy sufficiently to reach acceptable sensitivity thresholds. These findings suggest that NHANES protocols produce high levels of misclassification of periodontitis cases and thus have low validity for surveillance and research.

  10. Programa Bolsa Família e violência doméstica contra a mulher no Brasil

    Directory of Open Access Journals (Sweden)

    Gustavo Carvalho Moreira

    Full Text Available Resumo A violência contra as mulheres implica custos diretos e indiretos ao indivíduo, à família e à sociedade, atingindo principalmente as classes de baixa renda. Diante dessa realidade, o presente estudo procurou analisar como uma política pública de transferência de renda condicionada - Programa Bolsa Família (PBF é capaz de influenciar tal fenômeno. Os resultados encontrados apresentam evidências de que o PBF possui efeito de aumentar a violência contra a mulher. Ademais, aquelas domiciliadas no meio rural, com baixa escolaridade e com rendimentos relativamente menores aos do cônjuge são as que merecem maior atenção, uma vez que este grupo possui maior risco de sofrer violência. Como sugestão, as políticas públicas deveriam expandir a condicionalidade da saúde para a mulher por meio de ações educativas, como o acompanhamento da situação intrafamiliar, que é fornecido pela assistência social do Serviço de Proteção e Atendimento Integral à Família - PAIF.

    Full Text Available This article proposes a critical reflection and analyzes the factors that build, naturalize and reproduce social inequalities in the structuring and development of the current Brazilian society. Specifically, it faces this challenge through perceptions of maintenance on the relationships between women’s roles, based on the relationship between the matter of gender, the social protection system, and the role of power. This paper uses a privileged field for this reflection - the analysis of women beneficiary of the “Bolsa Familia” program as a locus of challenge for the action of Occupational Therapy - considering the historical and social consequences of the scenario in which these women are included and the consequent fragility with relational ties. It also analyzes the objectives proposed by the program and its possible contributions to the empowerment of women in the social context, besides being guided by the recent inclusion of the occupational therapist in the Unified Social Assistance System (SUAS, legitimizing its practice in the social field and opening possibilities for action in this system.

    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

    Full Text Available ABSTRACT A large number of studies have shown a potential association between periodontal and autoimmune diseases, such as rheumatoid arthritis and systemic lupus erythematosus (SLE. Similar mechanisms of tissue destruction concerning periodontitis and other autoimmune diseases have stimulated the study of a possible relationship between these conditions. This study aims to review the literature about this potential association and their different pathogenic mechanisms. Considering that periodontal disease is a disease characterized by inflammation influenced by infectious factors, such as SLE, it is plausible to suggest that SLE would influence periodontal disease and vice-versa. However, this issue is not yet fully elucidated and several mechanisms have been proposed to explain this association, as deregulation mainly in innate immune system, with action of phagocytic cells and proinflammatory cytokines such as IL-1β and IL-18 in both conditions’ pathogenesis, leading to tissue destruction. However, studies assessing the relationship between these diseases are scarce, and more studies focused on common immunological mechanisms should be conducted to further understanding.

  19. Aggressive periodontitis: The unsolved mystery.

    Science.gov (United States)

    Clark, Danielle; Febbraio, Maria; Levin, Liran

    2017-01-01

    Aggressive periodontal disease is an oral health mystery. Our current understanding of this disease is that specific bacteria invade the oral cavity and the host reacts with an inflammatory response leading to mass destruction of the alveolar bone. Aggressive periodontal disease is typically observed in a population under the age of 30 and occurs so rapidly that it is difficult to treat. Unfortunately, the consequence of this disease frequently involves tooth extractions. As a result, the aftermath is chewing disability and damage to self-esteem due to an altered self-image. Furthermore, patients are encumbered by frequent dental appointments which have an economic impact in regards to both personal financial strain and absent days in the workplace. Aggressive periodontal disease has a tremendous effect on patients' overall quality of life and needs to be investigated more extensively in order to develop methods for earlier definitive diagnosis and effective treatments. One of the mysteries of aggressive periodontal disease is the relatively nominal amount of plaque present on the tooth surface in relation to the large amount of bone loss. There seems to be a hidden factor that lies between the response by the patient's immune system and the bacterial threat that is present. A better mechanistic understanding of this disease is essential to provide meaningful care and better outcomes for patients.

    Full Text Available The objective of this study was to compare the periodontal status in postmenopausal women with osteopenia and osteoporosis. Material and Methods: We examined 43 postmenopausal women aged from 55 to 74 years. Material assessment of bones in every patient was performed by means of dual energy X-ray absorptiometry (DXA from two points on the skeleton – part of the femur neck and between the first and fourth lumbar vertebrae. A lipid blood test was done for patients of both groups. All patients were divided into two groups (the 1st with osteopenia, and the 2nd with osteoporosis. All patients were subjected to an oral clinical examination: the periodontal examination was composed of Plaque Index (PI, Pocket Score (PS, and Papillary Bleeding Index (PBI. X-ray analysis was performed for every patient. Results: The results of the clinical periodontal examination demonstrated that the mean PBI in patients in the 1st group had no significant differences from the PBI in patients in the 2nd group. PI value and PS findings in patients with general osteoporosis also had no statistical differences from the same parameters in patients with osteopenia. Conclusion: Under the circumstances of these patients’ characteristics and within the limits of the present study, we concluded that there is no significant difference in the periodontal status of postmenopausal women with systemic osteopenia and with osteoporosis.

    2017-01-01

    Periodontitis is a common inflammatory disease, which is initiated by bacterial infection and subsequently progressed by aberrant host response. It can result in the destruction of teeth supporting tissues and have an influence on systemic health. When periodontitis occurs, reactive oxygen species, which are overproduced mostly by hyperactive neutrophils, could not be balanced by antioxidant defense system and cause tissues damage. This is characterized by increased metabolites of lipid peroxidation, DNA damage and protein damage. Local and systemic activities of antioxidants can also be influenced by periodontitis. Total antioxidant capacity, total oxidant status and oxidative stress index have been used to evaluate the oxidative stress associated with periodontitis. Studies have confirmed that inflammatory response in periodontitis is associated with an increased local and systemic oxidative stress and compromised antioxidant capacity. Our review focuses on increased oxidative stress in periodontal disease, specifically, on the relationship between the local and systemic biomarkers of oxidative stress and periodontitis and their association with the pathogenesis of periodontitis. Also, the relationship between periodontitis and systemic inflammation, and the effects of periodontal therapy on oxidative stress parameters will be discussed. PMID:29180965

    2015-10-01

    Full Text Available Periodontal diseases are infectious diseases with a mixed microbial aetiology and marked inflammatory response leading to destruction of underlying tissue. Periodontal therapy aims to eliminate pathogens associated with the disease and attain periodontal health. Periodontitis is generally treated by nonsurgical mechanical debridement and regular periodontal maintenance care. Periodontal surgery may be indicated for some patients to improve access to the root surface; however, mechanical debridement alone may not be helpful in all cases. In such cases, adjunctive systemic antibiotic therapy remains the treatment of choice. It can reach microorganisms at the base of the deep periodontal pockets and furcation areas via serum, and also affects organisms residing within gingival epithelium and connective tissue. This review aims to provide an update on clinical issues regarding when and how to prescribe systemic antibiotics in periodontal therapy. The points discussed are the mode of antibiotic action, susceptible periodontal pathogens, antibiotic dosage, antibiotic use in treatment of periodontal disease, and mechanism of bacterial resistance to each antibiotic.

    Full Text Available Cigarette smoking is a major lifestyle-related risk factor for periodontal diseases. However, the pathophysiological role of cigarette smoking in periodontal disease has yet to be fully elucidated. Here we report that the systemic administration of cigarette smoke condensate or nicotine, which is the major ingredient of cigarette smoke, augmented alveolar bone loss. Concomitantly, the number of osteoclasts in periodontal tissues increased and the expression of receptor activator of nuclear factor κB ligand was upregulated at the ligated side in mice with periodontitis. Nicotine also attenuated alveolar bone repair after ligature removal. These observations highlight the destruction of periodontal tissue by smoking and the unfavorable clinical course of periodontal disease in patients with a cigarette smoking habit. The present study demonstrates that periodontal disease models are useful for elucidating the pathogenesis of cigarette smoking-related periodontal diseases.

    The primary ecological niche for suspected periodontal pathogens seems to be the subgingival area, even though periodontal pathogens are also frequently recovered from saliva. The interrelationship of different periodontal conditions and the salivary levels of suspected periodontal pathogens is not known. In the present study, salivary levels of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Campylobacter rectus, and Peptostreptococcus micros were determined by bacterial culture and related to clinical periodontal status in 40 subjects with either advanced, moderate, or initial/no periodontitis. Culture-positive subjects harbored the 5 bacterial species in mean numbers ranging from 2 x 10(5) to 6 x 10(7) colony-forming units (CFU)/mL saliva. A. actinomycetemcomitans was found in none and P. gingivalis in one of the subjects with initial periodontitis, whereas both species were found in 33% and 44%, respectively, of the subjects with moderate periodontitis and in 60% and 40%, respectively, of the subjects with advanced periodontitis. The mean numbers of CFU/mL of P. intermedia, C. rectus and P. micros were significantly higher in subjects with advanced periodontitis than in subjects with initial/no periodontitis. Ten patients with advanced periodontitis were treated mechanically and with adjunctive systemic metronidazole, and were re-examined 1 and 6 months after treatment. Periodontal treatment eradicated or significantly reduced the levels of salivary periodontal pathogens for half a year, whereas in untreated subjects, the levels and the detection frequencies generally remained fairly stable. In conclusion, the results showed that the salivary levels of periodontal pathogens reflect the periodontal status of the patient.

    Depressed chemotactic activity of polymorphoneutrophil (PMN) and monocyte (MN) appears to be one of the significant risk factors in the development of periodontal disease. Although bacteria are the primary etiologic factor in periodontal disease, the patient's host response is a determinant of disease susceptibility. Depressed chemotaxis of PMN and MN could lead to periodontal destruction by altering the host response i.e. impairment of the normal host response in neutralizing infection and alterations that result in destruction of the surrounding periodontal tissues. Thirty patients (10 healthy subjects, 10 chronic periodontitis, and 10 with aggressive periodontitis) participated in this study. Clinical parameters like plaque index, gingival index, probing pocket depth, and radiographic assessment were done. The peripheral blood PMNs and MNs were isolated from the patient and the chemotactic response was studied. Statistical analysis was performed using post-hoc Newman-Keul range test. PMN and MN chemotaxis was found to be statistically significant (Pperiodontal therapy in chronic and aggressive periodontitis group compared to healthy subjects. However on comparison between chronic and aggressive periodontitis group statistical significance was not found (P>0.05).Comparision between chronic periodontitis, aggressive periodontitis with healthy subjects, PMN and MN chemotaxis showed statistical significance (Pperiodontal therapy, Whereas statistically there was no difference when chronic periodontitis was compared with aggressive periodontitis. Depressed chemotaxis of PMN and MN results in increased periodontal destruction. In this study, depressed PMN and MN chemotaxis is seen in both aggressive periodontitis group and chronic periodontitis group and the response was altered although to a lesser degree after periodontal therapy in both groups indicating that effect of treatment does exist.

    Full Text Available Background: Calprotectin is a calcium-binding protein expressed by neutrophil, monocytes, gingival keratinocytes, and oral epithelial cells. The concentrations of calprotectin increase in plasma, urine and synovial fluid of patients with inflammatory diseases. This protein is known as a marker for periodontal diseases and is detected in gingival crevicular fluids. Purpose: This study was aimed to investigate the detection of inflammation on the aggressive periodontitis by calprotectin expression. Method: The gingival crevicular fluids were taken from five aggressive periodontitis patients and five healthy subjects by using sterile paper points. Calprotectin expression was analyzed by ELISA technique. Result: The results showed the significant difference in calprotectin expression between subject with aggressive periodontitis and healthy subjects p = 0.002 (p < 0.05. Conclusion: It was concluded that the calprotectin expression on the aggressive periodontitis patients may be useful for evaluation the progression of inflammation in periodontitis.

    Periodontitis is a complex, multifactorial disease and its susceptibility is genetically determined. The present book systematically reviews the evidence of the association between the genetic variants and periodontitis progression and/or treatment outcomes. Genetic syndromes known to be associated with periodontal disease, the candidate gene polymorphisms investigated in relation to periodontitis, the heritability of chronic and aggressive periodontitis, as well as common guidelines for association studies are described. This growing understanding of the role of genetic variation in inflammation and periodontal chronic disease presents opportunities to identify healthy persons who are at increased risk of disease and to potentially modify the trajectory of disease to prolong healthy aging. The book represents a new concept in periodontology with its pronounced focus on understanding through knowledge rather than presenting the presently valid answers. Connections between genetics and periodontology are systematically reviewed and covered in detail. (orig.)

    In this study, we investigated the periodontal regenerative potential of dental follicle cell (DFC) sheets and periodontal ligament cell (PDLC) sheets in the simulating inflammatory microenvironment of periodontitis, to confirm their regenerative potential for clinical application and explain the possible mechanism. The biological characteristics of DFC sheets and PDLC sheets were explored in lipopolysaccharide from Porphyromonas gingivalis (P. gingivalis LPS)-induced inflammation microenvironment in vitro, then cell sheets were transplanted into canine periodontal defects with experimental periodontitis in situ for 3 months. The results showed that P. gingivalis LPS greatly impaired the differentiation of PDLC sheets, whereas promoted gene expression of bone sialoprotein (BSP), osteopontin (OPN), and periostin (POSTN) in DFC sheets. LPS activated toll-like receptor 4 and NF-κB p65 phosphorylation in PDLC sheets. In experimental periodontitis, new periodontal attachment could be obtained in both PDLC sheets and DFC sheets. However, the complete periodontal regeneration, including periodontal ligament-cementum complex structure was observed only in DFC sheet groups, which also showed more alveolar bone formation than PDLC sheets. These results suggest that DFC sheets were more effective for periodontal regeneration in chronic inflammatory microenvironment of periodontitis. It is probably because of their ability to adapt the inflammatory environment and strong capacity to promote periodontal regeneration. This approach provides a tangible pathway toward clinical translation.

    Full Text Available Objective: To identify the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and low birth weight babies. Methods: A case-control study was conducted to determine the relationship between periodontitis in pregnant women through the periodontal disease index (PDI and the low birth weight babies (LBW. The participants were mothers with periodontitis and non-periodontitis mothers aged 20–35 years who gave birth in the Department of Obstetrics and Gynecology-Dr. Hasan Sadikin General Hospital, Bandung in the period of December to January 2005. Results: Based on the chisquare test results a highly significant relationship between periodontitis and low birth weight (p=0.002 was found. The Odd’s ratio showed that the risk of low birth weight in pregnant women with periodontitis was 15.58 times higher compared to those who did not suffer from periodontitis. The periodontal disease index has an accuracy of 88.6% in predicting the incidence of LBW. It strongly influenced the incidence of LBW with a high Odd’s ratio of 28.0. Pregnant women who suffer from periodontitis with a PDI > 3.25, have 19.2 times higher risk for delivering babies with LBW compared to the non-periodontitis mothers. Conclusions: The loss of attachment affects the possibility of delivering LBW babies.

    MicroRNAs (miRNAs) are a group of small RNAs that control gene expression in all aspects of eukaryotic life, primarily through RNA silencing mechanisms. The purpose of the present review is to introduce key miRNAs involved in periodontal homeostasis, summarize the mechanisms by which they affect downstream genes and tissues, and provide an introduction into the therapeutic potential of periodontal miRNAs. In general, miRNAs function synergistically to fine-tune the regulation of biological processes and to remove expression noise rather than by causing drastic changes in expression levels. In the periodontium, miRNAs play key roles in development and periodontal homeostasis and during the loss of periodontal tissue integrity as a result of periodontal disease. As part of the anabolic phase of periodontal homeostasis and periodontal development, miRNAs direct periodontal fibroblasts toward alveolar bone lineage differentiation and new bone formation through WNT, bone morphogenetic protein, and Notch signaling pathways. miRNAs contribute equally to the catabolic aspect of periodontal homeostasis as they affect osteoclastogenesis and osteoclast function, either by directly promoting osteoclast activity or by inhibiting osteoclast signaling intermediaries or through negative feedback loops. Their small size and ability to target multiple regulatory networks of related sets of genes have predisposed miRNAs to become ideal candidates for drug delivery and tissue regeneration. To address the immense therapeutic potential of miRNAs and their antagomirs, an ever growing number of delivery approaches toward clinical applications have been developed, including nanoparticle carriers and secondary structure interference inhibitor systems. However, only a fraction of the miRNAs involved in periodontal health and disease are known today. It is anticipated that continued research will lead to a more comprehensive understanding of the periodontal miRNA world, and a systematic

    To evaluate the association of oral Treponema (T.) spp. with severity of canine periodontitis, subgingival plaque samples of dogs of various breeds undergoing surgery were investigated. A wide range of oral Treponema spp. was analysed by a molecular and culture-independent approach applying DNA-DNA dot blot hybridization analysis and fluorescence in situ hybridization using Treponema specific oligonucleotide probes specific for phylogenetic groups I-VII of oral treponemes as well as probes specific for T. socranskii and T. denticola. To assess the periodontal status of affected dogs clinical parameters were measured and the periodontal status was classified from grade 0 (physiological periodont) to 3 (severe periodontitis). The periodontal status correlated significantly with an increasing concentration of volatile sulfur compounds (VSC, r=0.854) determined with a Halimeter, indicating a positive correlation between the presence of VSC-producing bacteria and periodontitis. In this study Treponema spp. of phylogenetic groups III, V-VII were not detected in any sample, whereas T. denticola-like treponemes were found only in 2 of 51 animals. However, treponemes belonging to phylogenetic groups I, II and IV of oral treponemes or T. socranskii were found in up to 64.84% of the dogs. The detection rate of Treponema spp. was significantly associated with an increased periodontal status. Treponemes present in periodontal lesions were also visualized by fluorescence in situ hybridization of gingival biopsies showing Treponema spp. not only in the microbial biofilm but also within the gingival tissue. The data presented here indicate that oral Treponema spp. are associated with canine periodontitis. Similar to human periodontitis, treponemes of groups I, II and IV and T. socranskii were found more frequently the higher the degree of periodontitis was.

No curto prazo, esses programas visam aliviar os problemas decorrentes da situação de pobreza, sendo que, no longo prazo, o objetivo é investir no capital humano, quebrando o ciclo intergeracional da pobreza. Estudos têm sido realizados para avaliar os impactos desses programas sobre variáveis como freqüência escolar, trabalho infantil, gastos com alimentação, entre outros. Este trabalho avalia o impacto da transferência de renda do Programa Bolsa Família sobre os gastos com alimentos de famílias rurais. As estimações foram feitas com base no método de Propensity Score Matching (PSM, que corrige para o viés de seleção amostral. Os resultados mostram que o valor médio das despesas anuais para as famílias beneficiárias supera em R$ 246 os gastos totais das famílias não-participantes. Considerando que a média anual recebida por essas famílias é de R$ 278, pode-se inferir que 88% desse valor é utilizado para consumo de alimento. Portanto, o programa de transferência condicionada Bolsa Família exerce um impacto positivo sobre o consumo de alimentos dessas famílias selecionadas.Conditional income transfer programs are social policies currently adopted to reduce poverty in several countries.

    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?

    The prevention and treatment of the periodontal diseases is based on accurate diagnosis, reduction or elimination of causative agents, risk management and correction of the harmful effects of disease. Prominent and confirmed risk factors or risk predictors for periodontitis in adults include smoking, diabetes, race, P. gingivalis, P. intermedia, low education, infrequent dental attendance and genetic influences. Several other specific periodontal bacteria, herpesviruses, increased age, male, sex, depression, race, traumatic occlusion and female osteoporosis in the presence of heavy dental calculus have been shown to be associated with loss of periodontal support and can be considered to be risk indicators of periodontitis. The presence of furcation involvement, tooth mobility, and a parafunctional habit without the use of a biteguard are associated with a poorer periodontal prognosis following periodontal therapy. An accurate diagnosis can only be made by a thorough evaluation of data that have been systematically collected by: 1) patient interview, 2) medical consultation as indicated, 3) clinical periodontal examination, 4) radiographic examination, and 5) laboratory tests as needed. Clinical signs of periodontal disease such as pocket depth, loss of clinical attachment and bone loss are cumulative measures of past disease. They do not provide the dentist with a current assessment of disease activity. In an attempt to improve the ability to predict future disease progression, several types of diagnostic tests have been studied, including host inflammatory products and mediators, enzymes, tissue breakdown products and subgingival temperature. In general, the usefulness of these tests for predicting future disease activity remains to be established in terms of sensitivity, specificity and predictive value. Although microbiological analysis of subgingival plaque is not necessary to diagnose and treat most patients with periodontitis, it is helpful when treating

    Periodontal and restorative dentistry are mutually important facets of clinical dentistry. Today's clinicians have many treatment options at their disposal, including biotolerant restorative materials and implants, to maintain periodontal health. It is crucial for the clinician to understand the biologic principles that form the foundation for restorative reconstruction of the periodontally involved tooth. This article discusses new techniques and trends in the critical management of the restorations, particularly at the gingival margins, and explores the role of implant dentistry as an option for the restorative plan of the periodontal patient.

    To explore the clinical characteristics of IgA nephropathy (IgAN) with severe chronic periodontitis and aggressive periodontitis. A total of 436 hospitalized patients who underwent renal needle biopsy in the department of nephrology of China-Japan Friendship Hospital from November 2013 to December 2014 were recruited in the study and blindly had periodontal examination. The patients were divided into IgAN group and non-IgAN group according to the renal pathology. The patients with IgAN were further categorized as non-periodontitis, chronic periodontitis and aggressive peridontitis group by Haas classification. The chronic periodontitis group was continually divided into mild, moderate and severe periodontitis group. The levels of interleukin (IL)-1β and IL-6 in gingival crevicular fluid were analyzed by enzyme-linked immunosorbent assays. The prevalence of periodontitis in the study was 88.3% (385/436). The prevalence of chronic periodontitis and aggressive periodontitis were higher in patients with IgAN than those with non-IgAN (Pperiodontitis was correlated with pathologic grading of IgAN (r=0.48, Pperiodontitis, those with severe chronic and aggressive periodontitis had more severe pathology, more frequent recurrent gross hematuria, higher levels of 24 h proteinuria, serum triglyceride and uric acid, higher periodontal probing depth and clinical attatchment level, as well as higer levels of IL-1β and IL-6, but had lower creatinine clearance rate (all Paggressive periodontitis was higher in patients with IgAN. Chronic periodontitis is correlated with the onset and development of IgAN. Patients with IgAN have worse condition with the aggravation of periodontitis.

    Immediate hypersensitivity reactions were induced in the periodontium and skin of monkeys sensitized with novo alcalase. Animals were challenged in the gingival papillae with 0.1, 1.0, and 10 micrograms of antigen for 1, 3, 5, or 7 consecutive days prior to sacrifice. At the same time, skin sites were challenged with 1 microgram of antigen. With repetitive immediate hypersensitivity reactions, the inflammatory infiltrate changed from one characterized by polymorphonuclear leukocytes to one characterized by plasma cells and lymphocytes. The repetitive gingival exposure to bacterial antigens which occur in periodontal disease could lead to repetitive immediate hypersensitivity reactions. Such reactions could play a role in the histopathology of human periodontal disease.

    To elucidate plausible associations between periodontal disease (PD) and pregnancy events through meta-analysis of original research published between 1998 and 2010. One hundred and twenty-five randomized, case-control, matched-cohort studies on pregnancy and postpartum specifics in women with PD are identified through PubMed, LILACS, and Cochrane Register. Meta-study is performed on a sample of 992 births allocated from studies of level I-II-1 evidence. An oral inflammation score (OIS) is composed from parameteric and observational components of maternal PD. Pearson arrival process is modeled for exchangeable correlations. Women with preeclampsia and preterm birth have poor periodontal parameters in both, treatment and placebo groups (OR 1.94-2.9). In puerperae with severe periodontitis birth weight is negatively correlated with maternal probing depth (r = -0.368), and C-reactive protein (r = -0.416). Higher rates of tobacco use (RR 3.02), bacterial vaginosis (RR 2.7), clinical attachment level (OR 2.76), and fetal tyrosine kinase (OR 1.6) contribute in increased rates of preeclamsia (RR 1.68), and prematurity (RR 2.75). After adding confounders into the model OIS remains significantly associated with preterm birth (OR 2.3). Maternal PD has strong associations with preeclampsia and prematurity.

    Full Text Available Estudos têm apontado possíveis relações de risco existentes entre doenças bucais, principalmente a doença periodontal, e complicações gestacionais, como parto prematuro, nascimento de recém-nascidos de baixo peso e pré-eclâmpsia. As explicações para tais hipóteses baseiam-se no fato de a doença periodontal ser de origem infecciosa, o que poderia provocar aumento de citocinas inflamatórias no sangue materno, por liberação direta da bolsa periodontal ou por disseminação de bactérias patogênicas, induzindo sua produção sistêmica. Esta suposição fundamenta-se no conhecimento de que a fisiopatologia das complicações obstétricas citadas está associada à presença de algumas citocinas no sangue materno. O presente trabalho teve como objetivo realizar revisão da literatura em busca de evidências para estas supostas associações. Apesar do grande número de estudos clínicos encontrados nesta revisão, observa-se a falta de padronização metodológica dos mesmos, fato que limita conclusões definitivas a respeito. Por outro lado, o fato de a doença periodontal ainda não ser comprovadamente um fator de risco para as complicações obstétricas não diminui a importância da manutenção da saúde bucal das gestantes, que devem apresentar condições orais que propiciem adequada alimentação, sem dor e sangramento, e assim manter seu aporte nutricional adequado.Studies have shown possible risk relations among oral illnesses, mainly periodontal disease and adverse pregnancy outcomes, such as prematurity, low birth weight and preeclampsia. The explanation for this hypothesis is based on the fact that periodontal disease is an infectious state, which may increase maternal serum cytokines through the release of such agents directly from the periodontal pocket or by through the dissemination of pathogenic bacteria, inducing systemic production.

    Objective Periodontal disease resolution was hypothesized to impact systemic HIV measures. Methods In this longitudinal cohort study, 73 HIV-positive subjects received comprehensive dental care. AAP, CDC/AAP and biofilm gingival interface case definitions determined periodontal classification. In a subset, IL-6 was measured. Multivariable binary logistic regression models estimated odds of periodontitis development for comparisons between HIV and NHANES (2009–12) groups. Results In both groups, moderate/severe periodontitis was positively associated with non-white race, smoking, male gender, low income and increased pro-inflammatory cytokines. Likelihood of HIV periodontitis was higher across demographic variables. Subjects with severe periodontitis on antiretroviral therapy demonstrated high plasma viral loads at baseline (median= 464 co/ml; mean 65,773 co/ml). Post intervention, HIV periodontitis distribution became similar to NHANES and IL-6 levels decreased 2-fold (p=0.07). Subjects with suppressed viral load at baseline demonstrated increased CD4 counts at 12 months post intervention (P=0.027) (n=26). Conclusions Smoking, being non-white and low income were associated with periodontitis in HIV and NHANES. Higher Il-6, higher HIV VL and lower CD4 were associated with moderate/severe periodontal disease. Periodontitis decreased significantly with treatment producing periodontal profiles mirroring the national norm. In a subset of suppressed subjects, decreased oral inflammation, and associated microbial translocation, yielded improved CD4 counts. PMID:27109277

    Periodontitis is an infectious/inflammatory disease characterized by the loss of periodontal ligament and alveolar bone. Herpesviruses are frequent inhabitants of periodontitis lesions, and the periodontopathogenicity of these viruses is the topic of this review. In 26 recent studies from 15 countries, subgingival cytomegalovirus, Epstein-Barr virus and herpes simplex virus type 1, respectively, yielded median prevalences of 49%, 45% and 63% in aggressive periodontitis, 40%, 32% and 45% in chronic periodontitis, and 3%, 7% and 12% in healthy periodontium. An active herpesvirus infection of the periodontium exhibits site specificity, is a potent stimulant of cellular immunity, may cause upgrowth of periodontopathic bacteria and tends to be related to disease-active periodontitis. Pro-inflammatory cytokines induced by the herpesvirus infection may activate matrix metalloproteinases and osteoclasts, leading to breakdown of the tooth-supportive tissues. The notion that a co-infection of herpesviruses and specific bacteria causes periodontitis provides a plausible etiopathogenic explanation for the disease. Moreover, herpesvirus virions from periodontal sites may dislodge into saliva or enter the systemic circulation and cause diseases beyond the periodontium. Periodontal treatment can diminish significantly the periodontal load of herpesviruses, which may lower the incidence and magnitude of herpesvirus dissemination within and between individuals, and subsequently the risk of acquiring a variety of medical diseases. Novel and more effective approaches to the prevention and treatment of periodontitis and related diseases may depend on a better understanding of the herpesvirus-bacteria-immune response axis. © 2015 John Wiley & Sons A/S.

    Full Text Available Abstract Background Bacteria in periodontal pockets develop complex sessile communities that attach to the tooth surface. These highly dynamic microfloral environments challenge both clinicians and researchers alike. The exploration of structural organisation and bacterial interactions within these biofilms is critically important for a thorough understanding of periodontal disease. In recent years, Filifactor alocis, a fastidious, Gram-positive, obligately anaerobic rod was repeatedly identified in periodontal lesions using DNA-based methods. It has been suggested to be a marker for periodontal deterioration. The present study investigated the epidemiology of F. alocis in periodontal pockets and analysed the spatial arrangement and architectural role of the organism in in vivo grown subgingival biofilms. Results A species-specific oligonucleotide probe, FIAL, was designed and evaluated. A total of 490 subgingival plaque samples were submitted to PCR and subsequent dot blot hybridization to compare the prevalence of F. alocis in patients suffering from generalized aggressive periodontitis (GAP, chronic periodontitis (CP, and control subjects resistant to periodontitis. Moreover, a specially designed carrier system was used to collect in vivo grown subgingival biofilms from GAP patients. Subsequent topographic analysis was performed using fluorescence in situ hybridization. While the majority of patients suffering from GAP or CP harboured F. alocis, it was rarely detected in the control group. In the examined carrier-borne biofilms the organism predominantly colonized apical parts of the pocket in close proximity to the soft tissues and was involved in numerous structures that constitute characteristic architectural features of subgingival periodontal biofilms. Conclusions F. alocis is likely to make a relevant contribution to the pathogenetic structure of biofilms accounting for periodontal inflammation and can be considered an excellent marker

    Periodontal disease is a chronic inflammatory disease of the jaws and is more prevalent in obesity. Local and systemic oxidative stress may be an early link between periodontal disease and obesity. The primary aim of this study was to detect whether increased periodontal disease susceptibility in obese individuals is associated with local and systemic oxidative stress. Accordingly; we analyzed periodontal status and systemic (serum) and local (gingival crevicular fluid [GCF]) oxidative status markers in young obese women in comparison with age-matched lean women.Twenty obese and 20 lean women participated. Periodontal condition was determined by clinical periodontal indices including probing depth, clinical attachment level, gingival index, gingival bleeding index, and plaque index. Anthropometric, hormonal, and metabolic measurements were also performed. Blood and GCF sampling was performed at the same time after an overnight fasting. Serum and GCF total antioxidant capacity (TAOC), and total oxidant status (TOS) levels were determined, and oxidative stress index (OSI) was calculated.Clinical periodontal analyses showed higher gingival index and gingival bleeding index in the obese group (P = 0.001 for both) with no significant difference in probing depth, clinical attachment level, and plaque index between the obese and the lean women. Oxidant status analyses revealed lower GCF and serum TAOC, and higher GCF and serum OSI values in the obese women (P periodontal indices showed significant correlations with body mass index, insulin, and lipid levels, and also oxidant status markers.Our results suggest that young obese, otherwise healthy, women show findings of early periodontal disease (gingival inflammation) compared with age-matched healthy lean women, and that local/periodontal oxidative stress generated by obesity seems to be associated with periodontal disease.

    Dimensions of periodontal tissues are thought to predispose to the development of periodontal disease in man and dogs. Several studies have suggested that thin gingiva correlates with an increased incidence of periodontal disease. In this study, we hypothesized that the dimensions of periodontal tissues will vary in different breeds of dogs and could possibly correlate with the incidence of periodontal disease. Forty-two jaws of dogs aged up to 5-years were examined post-mortem and gingival and alveolar bone thickness were measured using methods of transgingival probing and digital calipers, respectively. Dogs were divided into three groups based on their body weight. Group I (dogs compared with small and medium-sized breed dogs. Both gingival and alveolar bone dimensions may be predictors for severity of periodontal disease and influence clinical outcome in certain periodontal surgical procedures.

    A novel index, the periodontal inflamed surface area (PISA), represents the sum of the periodontal pocket depth of bleeding on probing (BOP)-positive sites. In the present study, we evaluated correlations between PISA and periodontal classifications, and examined PISA as an index integrating the discrete conventional periodontal indexes. This study was a cross-sectional subgroup analysis of data from a prospective cohort study investigating the association between chronic periodontitis and the clinical features of ankylosing spondylitis. Data from 84 patients without systemic diseases (the control group in the previous study) were analyzed in the present study. PISA values were positively correlated with conventional periodontal classifications (Spearman correlation coefficient=0.52; P variable. PISA is advantageous for quantifying periodontal inflammation and plaque accumulation.

Para tanto, foi utilizada a técnica de pareamento por escore de propensão, a fim de identificar mulheres e homens não atendidos pelo programa comparáveis a mulheres e homens atendidos. Com base na Pesquisa Nacional por Amostra de Domicílio de 2006, estimaram-se a jornada de trabalho doméstico, a participação no mercado de trabalho e as horas de trabalho remunerado de homens e mulheres. Os resultados não foram conclusivos para participação no mercado de trabalho. Para a jornada de trabalho remunerado, há indícios de que o Programa Bolsa Família reduza as horas trabalhadas de homens e mulheres. Para a jornada de trabalho doméstico, há indicativos de aumento de tempo de cuidado doméstico para mulheres e redução para homens. Os resultados da pesquisa sugerem que o programa reforçaria papéis tradicionais de gênero, não contribuindo para a individualização das mulheres pobres.

Fez-se uso combinado desses métodos em dois períodos: antes da implantação do Programa e após sua implantação. Os resultados revelaram que, após a implantação do Bolsa Família, o "ciclo da pobreza" apresentou sinais de ruptura, devido a uma tendência de convergência para níveis de renda mais elevados e probabilidade de mitigar a pobreza nas classes de renda menos favorecidas da população brasileira. Assim, no longo prazo, vislumbra-se a possibilidade de alterar e combater a dinâmica do ciclo da pobreza e exclusão social.

    Some studies have revealed the impact of the family welfare allowance based on the fulfillment of certain conditions on improving living conditions and access to health and education services in different countries. However, gaps persist relating to the evaluation of the benefits of such programs among the groups that have greater difficulty in gaining access to public services or advances in the quality of education and school performance. Moreover, there is limited evidence of adequacy of the program to the respective contexts of implementation, levels of adhesion and local cooperation and strategies adopted for integration with other social policy programs. The scope of this article is to discuss the findings of the study of the implementation of the "Bolsa Familia" in the Manguinhos shantytown area in Rio de Janeiro conducted in 2007 and 2008 based on semi-structured interviews with program officials and local stakeholders. In conclusion, the study shows that the sustainability of "Bolsa Familia" actions to reduce poverty and promote health equity calls for strengthening the vertical and horizontal communication channels between government levels, public managers and civil associations, recognition of the complexity of the local social demands and an intersectoral agenda.

    Periodontitis is a complex immune-inflammatory disease that results from a preestablished infection in gingiva, mainly due to Gram-negative bacteria that colonize deeper in gingival sulcus and latter periodontal pocket. Host inflammatory and immune responses have both protective and destructive roles. Although cytokines, prostaglandins, and proteases struggle against microbial burden, these molecules promote connective tissue loss and alveolar bone resorption, leading to several histopathological changes, namely destruction of periodontal ligament, deepening of periodontal pocket, and bone loss, which can converge to attain tooth loss. Despite the efforts of genomics, transcriptomics, proteomics/peptidomics, and metabolomics, there is no available biomarker for periodontitis diagnosis, prognosis, and treatment evaluation, which could assist on the established clinical evaluation. Nevertheless, some genes, transcripts, proteins and metabolites have already shown a different expression in healthy subjects and in patients. Though, so far, ‘omics approaches only disclosed the host inflammatory response as a consequence of microbial invasion in periodontitis and the diagnosis in periodontitis still relies on clinical parameters, thus a molecular tool for assessing periodontitis lacks in current dental medicine paradigm. Saliva and gingival crevicular fluid have been attracting researchers due to their diagnostic potential, ease, and noninvasive nature of collection. Each one of these fluids has some advantages and disadvantages that are discussed in this review. PMID:24828325

    Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, a defect in insulin action or a combination of both. Periodontitis is now considered a chronic localized infection of the oral cavity that can trigger inflammatory host immune responses at local and systemic levels, and can also be a source of bacteremia. It is now known that periodontitis has an influence on the pathogenesis of certain systemic diseases. The biological relationship between diabetes and periodontal disease is well documented. In the mid-90s sufficient scientific support for the association between diabetes and periodontitis was published, and periodontitis was designated as the sixth complication of diabetes. There have been studies that show an improvement in both clinical and immunological parameters of periodontitis and glycemic control in long-term diabetes after treatment of periodontal disease. In addition, scientific evidence confirms that poorer glycemic control contributes to a worse periodontal condition. The interplay between the 2 conditions highlights the importance of the need for a good communication between the internist and dentist about diabetic patients, considering always the possibility that the 2 diseases may be occurring simultaneously in order to ensure an early diagnosis of both.

    Diabetes mellitus and periodontal diseases are common chronic diseases in the United States. Periodontal infection may adversely affect glycemic control in people with diabetes. This article reviews the evidence regarding how treatment of periodontal diseases affects glycemic control. The review consisted of a MEDLINE literature search to identify primary research reports on the relationship between periodontal therapy and changes in glycemic control. The review identified three randomized clinical trials and nine nonrandomized clinical follow-up studies. The strength, quantity and breadth of evidence are varied, precluding clear-cut guidance for determining whether treating periodontal infection has a beneficial effect on glycemic control. Despite the variation and limitations in the literature, evidence supports the concept that periodontal diseases can contribute to poorer glycemic control in people with diabetes. Although the evidence is not unequivocal, it provides sufficient support for additional investigations of the effect of preventing and treating periodontal infections on managing glycemic control. Sufficient evidence exists to incorporate oral examinations and periodontal care in management regimens for people with diabetes. It is prudent to assess patients' glycemic control status and communicate the importance of referring patients with diabetes for thorough oral health evaluations and necessary care.

    Few epidemiologic studies have investigated aggressive periodontitis in Koreans, but such studies of disease prevalence and other clinical characteristics would be invaluable in providing proper treatment. The aim of this study was to assess the prevalence of aggressive periodontitis and to measure the extent of associated periodontal breakdown. The study population consisted of 1,692 patients who visited the Department of Periodontology, Wonkwang Daejeon Dental Hospital from January to December, 2010. Clinical parameters (probing depth, gingival recession, periodontal attachment loss) were measured by a single examiner, and radiographic examination was performed at the baseline. Twenty-eight (1.65%) patients showed clinical features of aggressive periodontitis, of which 27 patients exhibited the generalized form, and 1 exhibited the localized form. There was no significant difference between the percentage of male and female patients. The probing pocket depth of the maxillary first molar was deeper than that of the other teeth and gingival recession was also the most serious at the maxillary first molar. The periodontal attachment loss was the highest at the maxillary first molar. The average number of missing teeth was 1.29 per subject. Loss of the second molar was prominent. Within the limitations of this study, the periodontal breakdown evaluated by attachment loss was found to be most severe at the first molars of aggressive periodontitis patients. However, further large scale multicenter studies are necessary to access more precise data, including prevalence.

    2002-12-01

    The inflammatory and immune processes in periodontitis are complex and, although a great deal of information is available, many questions remain. Variation in human susceptibility to periodontitis has long been accepted, but the pathological basis of this is poorly understood. Similarly, we know little of the differences, if any, between the pathology of chronic and aggressive periodontitis. Genetics and environmental influences play a role in the susceptibility process, but if and how that translates through the immune and inflammatory processes to produce the plasma cell-dominated lesions seen in periodontitis remain to be elucidated. This review will focus on immunological aspects of the inflammatory changes seen in gingivitis and periodontitis, addressing both humoral and cellular responses to the microbial insult from dental plaque. A tendency for an individual or site to form an extensive plasma cell infiltrate may indicate an inability to defend against periodontopathogens and thus a predisposition to periodontitis. The issues to be considered include: 1) homing of immune and inflammatory cells to target tissues; 2) their local proliferation and synthetic activity; 3) the cytokine profile of the leukocytes; 4) the immunoglobulin subclasses of locally produced antibodies; 5) mucosal and systemic immune characteristics of the response; 6) the humoral immune response in periodontal health and disease states; and 7) the antigenic target of the immune response in periodontal lesions.

    Periodontitis is a chronic, multifactorial, polymicrobial disease causing inflammation in the supporting structures of the teeth. There is a plethora of nonoral risk factors which can be quoted to aid in the development of chronic periodontitis. According to WHO, depression is a common mental disorder that presents with depressed mood, loss of interest or pleasure, feelings of guilt, disturbed sleep or appetite, low energy and poor concentration. Depression is associated with negligent oral health care and another mechanism proposed disturbance in the hypothalamic-pituitary axis system and hypothalamic-pituitary-thyroid system, which can affect the periodontal status by affecting the immune system. The aim of this study was to assess the association between periodontal clinical parameters and depression rating. The study design is a case-control study with 35 patients each in case and control group. The periodontal parameters taken for measurement were probing depth and clinical attachment loss. Depression was calculated using Beck's depression scale. The statistical analysis was performed by means of SPSS software (SPSS Inc., Chicago, IL, USA; version 17.0 under windows 2000). Student's t-test was used to determine the relationship between the clinical periodontal parameters and depression. Self-reported scoring of depression by using Beck's depression inventory has shown that periodontal patients had a significantly higher total depression score than normal controls. This study reveals that there is a direct correlation between the severity of periodontal disease and the severity of depression in patients.

    This paper focused on the relationship between periodontitis and Type 2 diabetes mellitus (T2DM). There is an abundance of evidence that diabetes mellitus play important etiological roles in periodontal diseases. In addition, periodontal diseases have powerful and multiple influences on the occurrence and severity of systemic conditions and diseases, such as diabetes mellitus, cardiovascular disease, respiratory disease and pregnancy complications. The relationship of periodontitis and diabetes has been supported by sufficient evidences in the past twenty years: (1) diabetes is an independent risk factor of chronic periodontitis; (2) metabolic control will improve the prognosis of chronic periodontitis; (3) the treatment of chronic periodontitis will improve the metabolic level. Our recent investigation on periodontal status in the families of type 2 diabetes mellitus further confirmed the relationship. It was showed that the periodontal index such as probing depth (PD), attachment loss (AL) and numbers of tooth loss in diabetes family members were significantly higher than non-diabetes family members, while no difference of periodontal parameters was found between well control family members and non diabetes family members. In the development of type 2 diabetes (T2DM) and its complications, the advanced glycation end products (AGEs) and its receptors were to be recognized as important factors. The distributions of AGEs and the receptor for AGEs (RAGE) are highly consistent in various tissues. One study in our laboratory demonstrated that RAGE was strongly expressed in gingival tissues gathered from T2DM patients with periodontitis compared with systemically healthy chronic periodontitis patients, the expression of RAGE was positively correlated with the expression of TNF-alpha, indicating that AGE-RAGE pathway was involved in the development of periodontitis in T2DM patients. It is known that inflammation could induce the prediabetic status characterized by

    Full Text Available The purpose of this review is to highlight the orthodontics and periodontics interface in clinical practice for optimized treatment outcomes. Orthodontic treatment aims at providing an acceptable functional and esthetic occlusion. Tooth movements are strongly related to interactions of teeth with their supportive periodontal tissues. In recent years, due to the increased number of adult patients seeking orthodontic treatment, orthodontists frequently face patients with periodontal problems.Esthetic considerations, like uneven gingival margins or functional problems resulting from inflammatory periodontal diseases, should be considered in orthodontic treatment planning. Potentials and limitations that derive from the interdisciplinary approach of complex orthodontic-periodontal clinical problems are discussed along with the role of light forces and self-ligating brackets.

    Evolution of periodontal disease is one of the most important data for the clinicians in order to achieve correct planning and treatment. Clinical measure of the periodontal sulcus depth is the most important datum to know the exact state of periodontal disease. These measures must be done periodically study bone resorption evolution around teeth. Time factor of resorption indicates aggressiveness of periodontitis. Manual probes are commonly used with direct reading. Mechanical probes give automatic signal but this method uses complicated and heavy probes that are only limited for University researchers. Probe position must be the same to have right diagnosis. Digital image analysis of periodontal probing provides practical, accurate and easy tool. Gum and plaque index could also be digitally measured with this method.

    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)

    Full Text Available Influence of systemic disorders on periodontal diseases is well established. However, of growing interest is the effect of periodontal diseases on numerous systemic diseases or conditions like cardiovascular disease, cerebrovascular disease, diabetes, pre-term low birth weight babies, preeclampsia, respiratory infections and others including osteoporosis, cancer, rheumatoid arthritis, erectile dysfunction, Alzheimer′s disease, gastrointestinal disease, prostatitis, renal diseases, which has also been scientifically validated. This side of the oral-systemic link has been termed Periodontal Medicine and is potentially of great public health significance, as periodontal disease is largely preventable and in many instances readily treatable, hence, providing many new opportunities for preventing and improving prognosis of several systemic pathologic conditions. This review article highlights the importance of prevention and treatment of periodontal diseases as an essential part of preventive medicine to circumvent its deleterious effects on general health.

    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.

    2015-01-01

    Full Text Available Periodontal disease results from inflammation of the supporting structure of the teeth and in response to chronic infection caused by various periodontopathic bacteria. The mechanical removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have been the conventional methods of periodontal therapy. However, the removal of plaque and the reduction in the number of infectious organisms can be impaired in sites with difficult access. Photodynamic therapy (PDT is a powerful laser-initiated photochemical reaction, involving the use of a photoactive dye (photosensitizer activated by light of a specific wavelength in the presence of oxygen. Application of PDT in periodontics such as pocket debridement, gingivitis, and aggressive periodontitis continue to evolve into a mature clinical treatment modality and is considered as a promising novel approach for eradicating pathogenic bacteria in periodontitis.

    Wactawski-Wende, J

    2001-12-01

    There is increasing evidence that osteoporosis, and the underlying loss of bone mass characteristic of this disease, is associated with periodontal disease and tooth loss. Periodontitis has long been defined as an infection-mediated destruction of the alveolar bone and soft tissue attachment to the tooth, responsible for most tooth loss in adult populations. Current evidence including several prospective studies supports an association of osteoporosis with the onset and progression of periodontal disease in humans. The majority of studies have shown low bone mass to be independently associated with loss of alveolar crestal height and tooth loss. However studies that focus on the relation of clinical attachment loss and osteoporosis are less consistent. To date, the majority of studies on the relationship between periodontal disease and osteoporosis have been hindered by small sample sizes, limited control of other potential confounding factors, varying definitions of both periodontal disease and osteoporosis, and few prospective studies where the temporality of the association can be established. Potential mechanisms by which host factors may influence onset and progression of periodontal disease directly or indirectly include underlying low bone density in the oral cavity, bone loss as an inflammatory response to infection, genetic susceptibility, and shared exposure to risk factors. Systemic loss of bone density in osteoporosis, including that of the oral cavity, may provide a host system that is increasingly susceptible to infectious destruction of periodontal tissue. Studies have provided evidence that hormones, heredity, and other host factors influence periodontal disease incidence and severity. Both periodontal disease and osteoporosis are serious public-health concerns in the United States. Prevalence of both osteoporosis and tooth loss increase with advancing age in both women and men. Understanding the association between these common diseases and the

    Periodontal health can be restored through assessment, diagnosis, treatment and management of periodontal osseous defects by the periodontist-dental hygienist team. Treatment of periodontitis has evolved over time, with regenerative periodontal therapy at the forefront in cutting-edge periodontal care. While the techniques and materials available today are allowing therapists to push the limits of periodontal regeneration and achieve success in increasingly more difficult cases, the principles of successful regeneration remain the same. Case selection, identification and resolution of etiologic and contributing factors, proper surgical technique, follow-up and patient education are keys to obtaining a successful outcome. The impact of the dental hygienist in assessment and maintenance is highlighted. Literature review of the key research studies evaluating the etiology and contributing factors in the development osseous defects, osseous defect and tooth-related characteristics, and principles of successful regenerative therapy. The authors draw upon their experience with patient care and clinical research to synthesize the evidence relevant to today's dental hygienist. Periodontal regeneration is a well-supported and predictable therapy that can be utilized to restore periodontal support and health. The dental hygienist is key in assessing and caring for the periodontal health of patients over time. Identifying who may benefit from regenerative periodontal therapy is an essential skill for today's practicing dental hygienist. Copyright © 2014 Elsevier Inc. All rights reserved.

    Biomarkers are highly specific and sensitive indicators of disease activity. Resistin is a recently discovered adipocytokine, having a potent biomarker quality. Initially resistin was thought to be produced by adipocytes alone; however, emerging evidence suggests that it is also produced in abundance by various cells of the immunoinflammatory system, indicating its role in various chronic inflammatory diseases. Data suggests that resistin plays a role in obesity, insulin resistance, cardiovascular diseases, and periodontitis. Resistin derived its name from the original observation that it induced insulin resistance (resist-in: resist insulin) in mice and is downregulated in mature murine adipocytes cultured in the presence of insulin sensitizing drugs like thiazolidinediones. It is well recognized that obesity, is associated with insulin resistance and diabetes. A three-way relationship has been established between diabetes, obesity and periodontitis. Recent evidence also suggests an association between obesity and increased risk for periodontitis. Our previous research showed incremental elevation of resistin with periodontal disease activity and a reduced level of resistin, after periodontal therapy. Thus resistin would be one of the molecular links connecting obesity, periodontitis, and diabetes and may serve as a marker that links periodontal disease with other systemic diseases. A Medline/PubMed search was carried out for keywords "Diabetes Mellitus," "Periodontitis," and "Resistin," and all relevant research papers from 1990 in English were shortlisted and finalized based on their importance. This review provides an insight into the biological action of resistin and its possible role in periodontitis influenced diabetes mellitus and diabetes induced periodontitis.

    To derive from a validated questionnaire a periodontal screening score, intended as an user-friendly tool to identify individuals at risk of periodontitis in epidemiological studies. A French 12-item self-reported questionnaire was developed by translating English questions previously used for periodontitis screening and surveillance. After a cognitive evaluation, the questionnaire was validated in a sample of 232 individuals (mean age: 46.1±12.6 years) receiving full-mouth periodontal examination, including probing pocket depth and clinical attachment level recordings. Case definition was based on the American Academy of Periodontology/Centers for Disease Control and Prevention criteria. Logistic regression analyses and C-statistics were used to assess the validity and accuracy of the questionnaire and to develop the periodontal screening score. The sample was constituted of 109 individuals with severe periodontitis, who were compared with 123 individuals with no/moderate periodontitis. The questionnaire had moderate-to-high accuracy in identifying severe cases; the periodontal screening score (calculated on 5 self-report items, age, and smoking) showed a sensitivity of 78.9% and a specificity of 74.8%, with an area under the receiver operating characteristics curve of 0.821. The periodontal screening score represents a valuable and accurate tool to screen for severe periodontitis at the population level. This article is protected by copyright. All rights reserved.

    Implantation of periodontal ligament stem cells is emerging as a potential periodontal regenerative procedure. This systematic review considers the evidence from animal models investigating the use of periodontal ligament stem cells for successful periodontal regeneration. PubMed, Embase, MEDLINE and Google Scholar were searched to December 2013 for quantitative studies examining the outcome of implanting periodontal ligament stem cells into experimental periodontal defects in animals. Inclusion criteria were: implantation of periodontal ligament stem cells into surgically created periodontal defects for periodontal regeneration; animal models only; source of cells either human or animal; and published in English. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From the literature search, 43 studies met the inclusion criteria. A wide variety of surgical defects were created in four species of animal (dog, rat, pig and sheep). Owing to wide variability in defect type, cell source and cell scaffold, no meta-analysis was possible. Outcome measures included new bone, new cementum and new connective tissue formation. In 70.5% of the results, statistically significant improvements of these measures was recorded. These results are notable in that they indicate that irrespective of the defect type and animal model used, periodontal ligament stem cell implantation can be expected to result in a beneficial outcome for periodontal regeneration. It is recommended that there is sufficient evidence from preclinical animal studies to warrant moving to human studies to examine the efficacy, safety, feasibility (autologous vs. allogeneic transplantation) and delivery of periodontal ligament stem cells for periodontal regeneration. © 2014 John Wiley & Sons A/S.

    Chronic periodontitis is associated with systemic diseases such as atherosclerosis. In this study, we evaluated the efficacy of serum IgG antibody titer to periodontal bacteria for prognosis of periodontitis recurrence during supportive periodontal therapy (SPT) phase. The 139 patients during SPT phase were selected and divided to two groups as follows: "Stable" and "Recurrence" group at SPT phase for case-control study: "High IgG titer" and "Normal IgG titer" group before transition to SPT phase for cohort study. We examined whether clinical findings or serum IgG antibody titers to periodontal bacteria are risk factors for the development of periodontitis recurrence. Case-control study showed that there were significant differences between the stable and recurrence groups in age and number of teeth. The serum IgG antibody titer to Eikenella corrodens FDC1073, Porphyromonas gingivalis SU63, and Campylobacter rectus ATCC33238 was significantly higher in the recurrence group. Next, we found, that the recurrence ratio in the high IgG titer group to Gram-negative obligate anaerobe, Prevotella intermedia, Treponema denticola, and C. rectus was significantly higher than that of the normal IgG titer group. Taken together, serum IgG antibody titer test is useful in the prognosis of periodontitis recurrence during the SPT phase. © 2011 Wiley-Liss, Inc.

    Periodontal disease (PD) is one of the most commonly known human chronic disorders. The relationship between PD and several systemic diseases such as diabetes mellitus (DM) has been increasingly recognized over the past decades. The purpose of this review is to provide the reader with knowledge concerning the relationship between PD and DM. Many articles have been published in the English and Portuguese literature over the last 50 years examining the relationship between these two chronic diseases. Data interpretation is often confounded by varying definitions of DM, PD and different clinical criteria were applied to determine the prevalence, extent and severity of PD, levels of glycemic control and diabetes-related complications. This paper provides a broad overview of the predominant findings from research conducted using the BBO (Bibliografia Brasileira de Odontologia), MEDLINE, LILACS and PubMed for Controlled Trials databases, in English and Portuguese languages published from 1960 to October 2012. Primary research reports on investigations of relationships between DM/DM control, PD/periodontal treatment and PD/DM/diabetes-related complications identified relevant papers and meta-analyses published in this period. This paper describes the relationship between PD and DM and answers the following questions: 1- The effect of DM on PD, 2- The effects of glycemic control on PD and 3- The effects of PD on glycemic control and on diabetes-related complications. The scientific evidence reviewed supports diabetes having an adverse effect on periodontal health and PD having an adverse effect on glycemic control and on diabetes-related complications. Further research is needed to clarify these relationships and larger, prospective, controlled trials with ethnically diverse populations are warranted to establish that treating PD can positively influence glycemic control and possibly reduce the burden of diabetes-related complications.

    To evaluate bone loss around implants placed in patients with a history of treated chronic periodontitis and who did or did not attend supportive periodontal therapy, after one year in function. Furthermore, the influence of periodontal biotype and level of plaque was also evaluated. Forty-nine patients participated voluntarily in the study. All subjects had a history of chronic periodontitis, which had been previously treated. After the active treatment, 27 patients attended supportive periodontal therapy (SPT) and the rest did not (No SPT). The O'Leary plaque index and periodontal biotype were recorded for each subject and 246 Astra Tech® OsseospeedTM implants were radiographically analysed (123 placed in SPT patients and 123 in No SPT patients) at the time of loading and one year later, measuring marginal bone loss with the program Dental Studio NX 6.0®. The statistical analysis was performed with Windows SPSS, applying Pearson's correlation index and the Kruskal-Wallis and U-Mann Whitney non-parametric tests. Six patients were found to have periimplantitis and sixteen mucositis. The survival rate was 99.59% (100% SPT and 99.18% No SPT). Mean bone loss was 0.39 mm (range [-0.71 - 8.05]). Among SPT patients, 95% of the implants had losses less than or equal to the mean (mean bone loss of 0.16 mm) compared to 53.7% for the No SPT group (mean bone loss of 0.62 mm). A statistically significant relationship was demonstrated between bone loss around the implant and the patient's periodontal biotype and plaque index. The marginal bone loss around implants in patients with treated chronic periodontitis is minimal if they are in a controlled SPT programme and there is individual control of plaque index. Moreover, the presence of a thin periodontal biotype represents a risk factor for additional bone loss.

    In the next few years there will be a great increase in the percentage of the population aged over 65. Not only will they have more teeth than previous generations, but also a large number of implants. The increase in age is accompanied by an increase in the prevalence and incidence of periodontal diseases. In addition, there is a decrease in manual dexterity and an increase in co-morbidity and medications affecting the oral cavity. Dental care in aged care facilities can be poor and access to dental professionals difficult. This article discusses these issues. © 2015 Australian Dental Association.

    Full Text Available Systemic antibiotics in conjunction with scaling and root planing (SRP, can offer an additional benefit over SRP alone in the treatment of periodontitis, in terms of clinical attachment loss (CAL and pocket depth change, and reduced risk of additional CAL loss. However, antibiotics are not innocuous drugs. Their use should be justified on the basis of a clearly established need and should not be substituted for adequate local treatment. The aim of this review is to discuss the rationale, proper selection, dosage and duration for antibiotic therapy so as to optimize the usefulness of drug therapy.

    Periodontitis is a chronic inflammatory condition of the tissues that surround and support the teeth and is initiated by inappropriate and excessive immune responses to bacteria in subgingival dental plaque leading to loss of the integrity of the periodontium, compromised tooth function, and eventually tooth loss. Periodontitis is an economically important disease as it is time-consuming and expensive to treat. Periodontitis has a worldwide prevalence of 5–15% and the prevalence of severe disease in western populations has increased in recent decades. Furthermore, periodontitis is more common in smokers, in obesity, in people with diabetes, and in heart disease patients although the pathogenic processes underpinning these links are, as yet, poorly understood. Diagnosis and monitoring of periodontitis rely on traditional clinical examinations which are inadequate to predict patient susceptibility, disease activity, and response to treatment. Studies of the immunopathogenesis of periodontitis and analysis of mediators in saliva have allowed the identification of many potentially useful biomarkers. Convenient measurement of these biomarkers using chairside analytical devices could form the basis for diagnostic tests which will aid the clinician and the patient in periodontitis management; this review will summarise this field and will identify the experimental, technical, and clinical issues that remain to be addressed before such tests can be implemented.

    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.

    Full Text Available Curettage is used in periodontics to scrap off the gingival wall of a periodontal pocket, and is needed to reduce loss of attachment (LOA by developing new connective tissue attachment in patients with periodontitis. The purpose of this study was to evaluate the success of curettage by the formation of tissue attachment. This clinical experiment was done by comparing LOA before curettage, 2 weeks and 3 weeks after curettage on 30 teeth with the indication of curettage. Study population were periodontitis patient who attending dental clinic at Hospital University Science Malaysia (HUSM with inclusion criteria good general health condition, 18 to 55 years old male or female and presented with pocket depth > 3mm. The teeth were thoroughly scaling before intervention and evaluated by measuring the periodontal attachment before curettage, two weeks and three weeks after curettage. Repeated measure ANOVA and Paired T Test were used to analyze the data. The result of the study showed that there was reduction in the periodontal attachment loss in periodontitis patient after curettage either in the anterior or posterior teeth which were supported by statistical analysis. This study concluded that curettage could make reattachment of the tissue

  18. Periodontitis and Cognitive Decline in Alzheimer's Disease.

    Directory of Open Access Journals (Sweden)

    Mark Ide

    Full Text Available Periodontitis is common in the elderly and may become more common in Alzheimer's disease because of a reduced ability to take care of oral hygiene as the disease progresses. Elevated antibodies to periodontal bacteria are associated with an increased systemic pro-inflammatory state. Elsewhere raised serum pro-inflammatory cytokines have been associated with an increased rate of cognitive decline in Alzheimer's disease. We hypothesized that periodontitis would be associated with increased dementia severity and a more rapid cognitive decline in Alzheimer's disease. We aimed to determine if periodontitis in Alzheimer's disease is associated with both increased dementia severity and cognitive decline, and an increased systemic pro inflammatory state. In a six month observational cohort study 60 community dwelling participants with mild to moderate Alzheimer's Disease were cognitively assessed and a blood sample taken for systemic inflammatory markers. Dental health was assessed by a dental hygienist, blind to cognitive outcomes. All assessments were repeated at six months. The presence of periodontitis at baseline was not related to baseline cognitive state but was associated with a six fold increase in the rate of cognitive decline as assessed by the ADAS-cog over a six month follow up period. Periodontitis at baseline was associated with a relative increase in the pro-inflammatory state over the six month follow up period. Our data showed that periodontitis is associated with an increase in cognitive decline in Alzheimer's Disease, independent to baseline cognitive state, which may be mediated through effects on systemic inflammation.

    2014-01-01

    Full Text Available To investigate the correlation between postmenopausal osteoporosis (PMO and the pathogenesis of periodontitis, ovariectomized rats were generated and the experimental periodontitis was induced using a silk ligature. The inflammatory factors and bone metabolic markers were measured in the serum and periodontal tissues of ovariectomized rats using an automatic chemistry analyzer, enzyme-linked immunosorbent assays, and immunohistochemistry. The bone mineral density of whole body, pelvis, and spine was analyzed using dual-energy X-ray absorptiometry and image analysis. All data were analyzed using SPSS 13.0 statistical software. It was found that ovariectomy could upregulate the expression of interleukin- (IL-6, the receptor activator of nuclear factor-κB ligand (RANKL, and osteoprotegerin (OPG and downregulate IL-10 expression in periodontal tissues, which resulted in progressive alveolar bone loss in experimental periodontitis. This study indicates that changes of cytokines and bone turnover markers in the periodontal tissues of ovariectomized rats contribute to the damage of periodontal tissues.

    The aim of this study was to investigate the potential relationship between alexithymia and chronic periodontitis. A case-control study of 222 male and female subjects aged 21-63 years was conducted. The participants were divided into a chronic periodontitis group (n = 114) and a control group (n = 108) with no history of periodontitis. The Toronto Alexithymia Scale (TAS-20) was used to evaluate alexithymia status of the subjects. Clinical data were collected on parameters such as the plaque index, bleeding on probing, probing depth, and the clinical attachment level (CAL). Socioeconomic data on the patients were also recorded. Chronic periodontitis group showed higher frequency in alexithymic patients as compared to control group. The proportion of high dental anxiety did not differ between the groups. The total TAS-20 score was statistically significantly higher in male subjects than in female subjects (P psychometric measures and the periodontal parameters revealed positive correlations with the severity of periodontal disease/CAL and the total TAS-20 score (P periodontitis. Further research is needed to identify the underlying mechanism.

    Full Text Available Aggressive periodontitis is characterized by a rapid and severe periodontal destruction in young systemically healthy subjects. A greater prevalence is reported in Africans and African descendent groups than in Caucasians and Hispanics. We first fine mapped the interval 1q24.2 to 1q31.3 suggested as containing an aggressive periodontitis locus. Three hundred and eighty-nine subjects from 55 pedigrees were studied. Saliva samples were collected from all subjects, and DNA was extracted. Twenty-one single nucleotide polymorphisms were selected and analyzed by standard polymerase chain reaction using TaqMan chemistry. Non-parametric linkage and transmission distortion analyses were performed. Although linkage results were negative, statistically significant association between two markers, rs1935881 and rs1342913, in the FAM5C gene and aggressive periodontitis (p = 0.03 was found. Haplotype analysis showed an association between aggressive periodontitis and the haplotype A-G (rs1935881-rs1342913; p = 0.009. Sequence analysis of FAM5C coding regions did not disclose any mutations, but two variants in conserved intronic regions of FAM5C, rs57694932 and rs10494634, were found. However, these two variants are not associated with aggressive periodontitis. Secondly, we investigated the pattern of FAM5C expression in aggressive periodontitis lesions and its possible correlations with inflammatory/immunological factors and pathogens commonly associated with periodontal diseases. FAM5C mRNA expression was significantly higher in diseased versus healthy sites, and was found to be correlated to the IL-1beta, IL-17A, IL-4 and RANKL mRNA levels. No correlations were found between FAM5C levels and the presence and load of red complex periodontopathogens or Aggregatibacter actinomycetemcomitans. This study provides evidence that FAM5C contributes to aggressive periodontitis.

    The purpose of this study was to compare periodontal status of postmenopausal women with mild to moderate osteoporosis who use risedronate therapy with those who do not. In this cross-sectional study, a total of 60 age-matched postmenopausal women with mild to moderate osteoporosis diagnosed by a bone density scan T score below -2.5 at either spine or hip were divided into two groups. Women in the experimental group had used systemic risedronate once weekly (35 mg) for at least 3 months. Women in the control group had never used bisphosphonate therapy. The periodontal status of each subject was evaluated through a clinical periodontal examination including evaluation of periodontal probing depth, gingival recession, gingival index, plaque score, attachment loss, and alveolar bone level. The significance in differences between the two groups was assessed using two-tailed paired t tests. Significant differences (P periodontal probing depth (2.6 vs 2.9 mm), gingival index (0.37 vs 0.71), plaque score (56.2 vs 77.0), attachment loss (2.8 vs 3.2 mm), and alveolar bone level (3.1 and 4.0), respectively. Gingival recession parameters did not differ significantly. Five of six periodontal parameters evaluated show that postmenopausal women with mild to moderate osteoporosis using risedronate therapy have healthier periodontal status than those who do not use bisphosphonates. Women using risedronate therapy show significantly less plaque accumulation, less gingival inflammation, lower probing depths, less periodontal attachment loss, and greater alveolar bone levels. These observations suggest that risedronate therapy may play a beneficial role in periodontal status.

    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.

  5. Neutrophil Functions in Periodontal Homeostasis

    Directory of Open Access Journals (Sweden)

    Ricarda Cortés-Vieyra

    2016-01-01

    Full Text Available Oral tissues are constantly exposed to damage from the mechanical effort of eating and to microorganisms, mostly bacteria. In healthy gingiva tissue remodeling and a balance between bacteria and innate immune cells are maintained. However, excess of bacteria biofilm (plaque creates an inflammation state that recruits more immune cells, mainly neutrophils to the gingiva. Neutrophils create a barrier for bacteria to reach inside tissues. When neutrophils are insufficient, bacteria thrive causing more inflammation that has been associated with systemic effects on other conditions such as atherosclerosis, diabetes, and cancer. But paradoxically when neutrophils persist, they can also promote a chronic inflammatory state that leads to periodontitis, a condition that leads to damage of the bone-supporting tissues. In periodontitis, bone loss is a serious complication. How a neutrophil balance is needed for maintaining healthy oral tissues is the focus of this review. We present recent evidence on how alterations in neutrophil number and function can lead to inflammatory bone loss, and how some oral bacteria signal neutrophils to block their antimicrobial functions and promote an inflammatory state. Also, based on this new information, novel therapeutic approaches are discussed.

    Full Text Available Recent epidemiological studies reveal that more than two-third of the world′s population suffers from one of the chronic forms of periodontal disease. The primary etiological agent of this inflammatory disease is a polymicrobial complex, predominantly Gram negative anaerobic or facultative bacteria within the sub-gingival biofilm. These bacterial species initiate the production of various cytokines such as interleukin-8 and TNF-α, further causing an increase in number and activity of polymorphonucleocytes (PMN along with these cytokines, PMNs also produce reactive oxygen species (ROS superoxide via the respiratory burst mechanism as the part of the defence response to infection. ROS just like the interleukins have deleterious effects on tissue cells when produced in excess. To counter the harmful effects of ROS, human body has its own defence mechanisms to eliminate them as soon as they are formed. The aim of this review is to focus on the role of different free radicals, ROS, and antioxidants in the pathophysiology of periodontal tissue destruction.

    The purpose of this study was to compare salivary calcium (Ca) level in smokers and non-smokers with chronic periodontitis, aggressive periodontitis, and healthy controls. 56 subjects were included in the study and were grouped as follows: 12 subjects who were periodontally healthy (Group I), 12 subjects having chronic periodontitis who were non-smokers (Group II), 12 non-smokers having aggressive periodontitis (Group III), 12 smokers with chronic periodontitis (Group IV), and 8 smokers with aggressive periodontitis (Group V). Clinical measurements and non-stimulated whole saliva samples were obtained and analyzed for Ca levels by ion-selective electrolyte analyzer. When salivary Ca values were compared between the groups, they showed statistically significant values (P periodontitis and smokers with aggressive periodontitis, respectively, than in other groups. Between groups II and III also, the mean salivary Ca level was statistically significant (P periodontitis than in non-smokers having aggressive periodontitis. The present study showed that smokers having chronic periodontitis as well as smokers having aggressive periodontitis have higher salivary calcium levels. Also, patients with aggressive periodontitis were found to have lesser salivary calcium level than chronic periodontitis patients by ion-selective electrolyte analyzer.

    2012-07-01

    Periodontal and endodontic diseases are inflammatory responses leading to periodontal and pulpal tissue loss. Regenerative therapies aim to restore the lost structures to vitality and function. Various materials and treatments methods have been used such as bone grafts, guided tissue regeneration, enamel matrix derivatives, growth and differentiation factors, and stem cells. Although the current materials and methods demonstrated adequate clinical results, true and complete biological tissue regeneration is not yet attainable. The current article reviews chronologically the materials and methods used in periodontal and endodontic regeneration highlighting their clinical success and shortcomings, and discussing future directions in regenerative therapy.

    The impact of smoking on general health has been widely studied and is directly related to several important medical problems including cancer, low birth weight, and pulmonary and cardiovascular disease. In the past 25 years, there has also been an increasing awareness of the role of cigarette consumption in oral health problems such as periodontal disease. Smoking is considered the major risk factor in the prevalence, extent and severity of periodontal diseases. This article will discuss the available evidence and provide the reader with an overview of the impact of smoking and its cessation on the pathogenesis and treatment of periodontal diseases.

  10. The antioxidant master glutathione and periodontal health

    Directory of Open Access Journals (Sweden)

    Vivek Kumar Bains

    2015-01-01

    Full Text Available Glutathione, considered to be the master antioxidant (AO, is the most-important redox regulator that controls inflammatory processes, and thus damage to the periodontium. Periodontitis patients have reduced total AO capacity in whole saliva, and lower concentrations of reduced glutathione (GSH in serum and gingival crevicular fluid, and periodontal therapy restores the redox balance. Therapeutic considerations for the adjunctive use of glutathione in management of periodontitis, in limiting the tissue damage associated with oxidative stress, and enhancing wound healing cannot be underestimated, but need to be evaluated further through multi-centered randomized controlled trials.

    2016-01-01

    We report a case of generalized chronic periodontitis and type 2 diabetes mellitus requiring periodontal treatment including regenerative therapy. The patient was a 66-year-old man who presented with the chief complaint of gingival inflammation and mobile teeth in the molar region. He had been being treated for type 2 diabetes mellitus since 1999. His glycated hemoglobin (HbA1c) level was 7.8%. An initial examination revealed sites with a probing depth of ≥7 mm in the molar region, and radiography revealed angular bone defects in this area. Based on a clinical diagnosis of generalized chronic periodontitis, the patient underwent initial periodontal therapy. An improvement was observed in periodontal conditions on reevaluation, and his HbA1c level showed a reduction to 6.9%. Periodontal regenerative therapy with enamel matrix derivative was then performed on #16, 26, and 27. Following another reevaluation, a removable partial denture was fabricated for #47 and the patient placed on supportive periodontal therapy (SPT). To date, periodontal conditions have remained stable and the patient's HbA1c level has increased to 7.5% during SPT. The results show the importance of collaboration between dentist and physician in managing periodontal and diabetic conditions in such patients.

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

    Directory of Open Access Journals (Sweden)

    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

    2007-01-01

    Aggressive periodontitis renders a great challenge to clinicians with regards to treatment and prosthodontic rehabilitation. A compromised remaining dentition and a tendency toward refractory disease make it difficult to establish a treatment plan that renders an adequate long-term prognosis. Although the use of implants has become a common treatment modality, limited data are available on the use of dental implants in patients with aggressive periodontitis, especially for cases necessitating the use grafting procedures preceding implant placement. In this case report the successful treatment of a patient with aggressive periodontitis by the combined use of periodontal and implant treatment necessitating preceding augmentive procedures is described.

    2017-01-01

    Purpose A novel index, the periodontal inflamed surface area (PISA), represents the sum of the periodontal pocket depth of bleeding on probing (BOP)-positive sites. In the present study, we evaluated correlations between PISA and periodontal classifications, and examined PISA as an index integrating the discrete conventional periodontal indexes. Methods This study was a cross-sectional subgroup analysis of data from a prospective cohort study investigating the association between chronic periodontitis and the clinical features of ankylosing spondylitis. Data from 84 patients without systemic diseases (the control group in the previous study) were analyzed in the present study. Results PISA values were positively correlated with conventional periodontal classifications (Spearman correlation coefficient=0.52; Pperiodontal indexes, such as BOP and the plaque index (PI) (r=0.94; Pperiodontal classification, PI, bleeding index, and smoking, but not in the multivariate analysis. In the multivariate linear regression analysis, PISA values were positively correlated with the quantity of current smoking, PI, and severity of periodontal disease. Conclusions PISA integrates multiple periodontal indexes, such as probing pocket depth, BOP, and PI into a numerical variable. PISA is advantageous for quantifying periodontal inflammation and plaque accumulation. PMID:29093989

    Periodontitis is driven by disproportionate host inflammatory immune responses induced by an imbalance in the composition of oral bacteria; this instigates microbial dysbiosis, along with failed resolution of the chronic destructive inflammation. The objectives of this study were to identify microbial signatures for health and chronic periodontitis at the genus level and to propose a model of dysbiosis, including the calculation of bacterial ratios. Published sequencing data obtained from several different studies (196 subgingival samples from patients with chronic periodontitis and 422 subgingival samples from healthy subjects) were pooled and subjected to a new microbiota analysis using the same Visualization and Analysis of Microbial Population Structures (VAMPS) pipeline, to identify microbiota specific to health and disease. Microbiota were visualized using CoNet and Cytoscape. Dysbiosis ratios, defined as the percentage of genera associated with disease relative to the percentage of genera associated with health, were calculated to distinguish disease from health. Correlations between the proposed dysbiosis ratio and the periodontal pocket depth were tested with a different set of data obtained from a recent study, to confirm the relevance of the ratio as a potential indicator of dysbiosis. Beta diversity showed significant clustering of periodontitis-associated microbiota, at the genus level, according to the clinical status and independent of the methods used. Specific genera ( Veillonella , Neisseria , Rothia , Corynebacterium , and Actinomyces ) were highly prevalent (>95%) in health, while other genera ( Eubacterium , Campylobacter , Treponema , and Tannerella ) were associated with chronic periodontitis. The calculation of dysbiosis ratios based on the relative abundance of the genera found in health versus periodontitis was tested. Nonperiodontitis samples were significantly identifiable by low ratios, compared to chronic periodontitis samples. When

    2014-01-01

    Treatment of periodontal disease is a complex and multidisciplinary procedure, requiring periodontal, surgical, restorative, and orthodontic treatment modalities. Several authors attempted to formulate models for periodontal treatment that orders the treatment steps in a logical and easy to remember manner. In this article, we discuss two models of periodontal treatment planning from two of the most well-known textbook in the specialty of periodontics internationally. Then modify them to arrive at a new model of periodontal treatment planning, The Trimeric Model. Adding restorative and orthodontic interrelationships with periodontal treatment allows us to expand this model into the Extended Trimeric Model of periodontal treatment planning. These models will provide a logical framework and a clear order of the treatment of periodontal disease for general practitioners and periodontists alike. PMID:25177662

    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.

    We have, in this preliminary study, investigated the use of optical coherence tomography for diagnosis of periodontal disease. We took in vitro OCT images of the dental and periodontal tissues from a young pig and compared them to histological sections. These images distinguish tooth and soft tissue relationships that are important in diagnosing and assessing periodontal disease. We have imaged the attachment of gingiva to the tooth surface and located the cemento-enamel junction. This junction is an important reference point for defining attachment level in the diagnosis of periodontal disease. the boundary between enamel and dentin is also visible for most of the length of the anatomical crown, allowing quantitation of enamel thickness and character.

    Full Text Available Epigenome refers to "epi" meaning outside the "genome." Epigenetics is the field of study of the epigenome. Epigenetic modifications include changes in the promoter CpG Islands, modifications of histone protein structure, posttranslational repression by micro-RNA which contributes to the alteration of gene expression. Epigenetics provides an understanding of the role of gene-environment interactions on disease phenotype especially in complex multifactorial diseases. Periodontitis is a chronic inflammatory disorder that affects the supporting structures of the tooth. The role of the genome (in terms of genetic polymorphisms in periodontitis pathogenesis has been examined in numerous studies, and chronic periodontitis has been established as a polygenic disorder. The potential role of epigenetic modifications in the various facets of pathogenesis of periodontitis is discussed in this paper based on the available literature.

    The aim of the present study was to examine tissue integration of implants placed (i) in subjects who had lost teeth because of advanced periodontal disease or for other reasons, (ii) in the posterior maxilla exhibiting varying amounts of mineralized bone. Thirty-six subjects were enrolled; 19 had lost teeth because of advanced periodontitis (group P) while the remaining 17 subjects had suffered tooth loss from other reasons (group NP). As part of site preparation for implant placement, a 3 mm trephine drill was used to remove one or more 2 mm wide and 5-6 mm long block of hard tissue [biopsy site; Lindhe et al. (2011). Clinical of Oral Implants Research, DOI: 10.1111/j.1600-0501.2011.02205.x]. Lateral to the biopsy site a twist drill (diameter 2 mm) was used to prepare the hard tissue in the posterior maxilla for the placement of a screw-shaped, self-tapping micro-implant (implant site). The implants used were 5 mm long, had a diameter of 2.2 mm. After 3 months of healing, the micro-implants with surrounding hard tissue cores were retrieved using a trephine drill. The tissue was processed for ground sectioning. The blocks were cut parallel to the long axis of the implant and reduced to a thickness of about 20 μm and stained in toluidine blue. The percentage of (i) implant surface that was in contact with mineralized bone as well as (ii) the amount of bone present within the threads of the micro-implants (percentage bone area) was determined. Healing including hard tissue formation around implants placed in the posterior maxilla was similar in periodontitis susceptible and non-susceptible subjects. Thus, the degree of bone-to-implant contact (about 59%) as well as the amount of mineralized bone within threads of the micro-implant (about 45-50%) was similar in the two groups of subjects. Pearson's coefficient disclosed that there was a weak negative correlation (-0.49; P < 0.05) between volume of fibrous tissue (biopsy sites) and the length of bone to implant

    Directory of Open Access Journals (Sweden)

    Mlachkova Antoaneta M.

    2014-08-01

    Full Text Available INTRODUCTION: Chronic periodontitis is defined as an inflammatory disease of the supporting tissues of teeth caused by microorganisms in the dental biofilm, resulting in progressive destruction of the periodontal ligament and alveolar bone with pocket formation and gingival recession. Treatment of chronic periodontitis aims at arresting the inflammation and stopping the loss of attachment by removal and control of the supra- and subgingival biofilm and establishing a local environment and microflora compatible with periodontal health. The AIM of this study was to evaluate the effectiveness of non-surgical therapy (scaling and root planning in the treatment of moderate chronic periodontitis. MATERIALS AND METHODS: The study included 30 patients aged between 33 and 75 years, of which 46.7% women and 53.3% men, diagnosed with moderate and, at some sites, severe periodontitis. They were treated with non-surgical periodontal therapy methods (scaling and root planning and curettage if indicated. Additionally, chemical plaque control with rinse water containing chlorhexidine was applied. The diagnostic and reassessment procedures included measuring the periodontal indices of 601 periodontal units before and after the therapy. The indices measured were the papillary bleeding index (PBI, the hygiene index (HI, the probing pocket depth (PPD and the clinical attachment level (CAL. RESULTS: Significant reduction of plaque and gingival inflammation was found in all treated patients; we also found a statistically significant reduction of periodontal pockets with clinically measured depth ⋋ 5 mm (PD ⋋ 5 mm. Pockets with PD > 5 mm did not show statistically significant lower incidence rates probably due to the initially small percentage of deep pockets in the patients studied. There was a statistically significant reduction of all sites with attachment loss, the highest significance found at sites where the attachment loss was greater than 5 mm. CONCLUSION

    Full Text Available Proteins are the building blocks for both microorganisms and periodontium. Periodontitis is the result of complex interrelationship between infectious agents and host factors. The onset, progression and severity of periodontal disease are mainly mediated by various protein molecules. The study of proteins as biomarkers in periodontal diseases has increased attention during the last few years. The proteins involved in pathogenesis of periodontal disease can be used as biomarkers. The knowledge of various proteins involved in periodontal disease pathogenesis can be used in the diagnosis, prevention and treatment of periodontal diseases.

    Oro-facial clefts are one of the most common birth defects and may be associated with other genetic anomalies. Aggressive periodontitis is a rare condition that progresses rapidly, but affects only a small percentage of the population. Most of the cases of aggressive periodontitis are familial. Even though, literature has documented the association of various genetic disorders with aggressive periodontitis, the aggressive periodontitis in patients with isolated cleft lip (CL) have never been addressed. Here, we report a rare case of isolated CL with generalized aggressive periodontitis. The concomitant presentation of isolated CL with aggressive periodontitis in an individual has clinical significance for multi-disciplinary care.

    2002-04-01

    A multifaceted antimicrobial approach is necessary for the successful management of destructive periodontal disease. Effective antimicrobial periodontal therapy aims to overwhelm periodontal pathogens with aggressive initial therapy and prevent previously suppressed pathogens from rising up anew through daily oral hygiene measures and frequent professional cleaning. Current antimicrobial periodontal therapy employs mechanical debridement performed with and without surgery, antibiotics, and antiseptics. Subgingival irrigation with povidone-iodine at the dentist's office and subgingival irrigation with dilute sodium hypochlorite for home-care constitute effective, safe, and affordable periodontal antimicrobial therapy. This article describes theoretical and practical guidelines for implementing rational and cost-effective antimicrobial principles in the management of periodontal disease.

    Enterococcus faecalis may contribute to periodontal breakdown in heavily infected subgingival sites, particularly in patients responding poorly to mechanical forms of periodontal therapy. Because only limited data are available on the antimicrobial sensitivity of enterococci of subgingival origin, this study evaluates the in vitro antibiotic susceptibility of E. faecalis isolated from periodontitis patients in the United States. Pure cultures of 47 subgingival E. faecalis clinical isolates were each inoculated onto specially prepared broth microdilution susceptibility panels containing vancomycin, teicoplanin, and six oral antibiotics of potential use in periodontal therapy. After incubation in ambient air for 18 to 20 hours, minimal inhibitory drug concentrations were determined using applicable Clinical and Laboratory Standards Institute criteria and interpretative guidelines. The organisms were additionally evaluated for in vitro resistance to metronidazole at 4 μg/mL. Periodontal E. faecalis exhibited substantial in vitro resistance to tetracycline (53.2% resistant), erythromycin (80.8% resistant or intermediate resistant), clindamycin (100% resistant to 2 μg/mL), and metronidazole (100% resistant to 4 μg/mL). In comparison, the clinical isolates were generally sensitive to ciprofloxacin (89.4% susceptible; 10.6% intermediate resistant) and 100% susceptible in vitro to ampicillin, amoxicillin/clavulanate, vancomycin, and teicoplanin. Tetracycline, erythromycin, clindamycin, and metronidazole revealed poor in vitro activity against human subgingival E. faecalis clinical isolates, and would likely be ineffective therapeutic agents against these species in periodontal pockets. Among orally administered antibiotics, ampicillin, amoxicillin/clavulanate, and ciprofloxacin exhibited marked in vitro inhibitory activity against periodontal E. faecalis, and may be clinically useful in treatment of periodontal infections involving enterococci.

    For a successful clinical outcome, periodontal regeneration requires the coordinated response of multiple soft and hard tissues (periodontal ligament, gingiva, cementum, and bone) during the wound-healing process. Tissue-engineered constructs for regeneration of the periodontium must be of a complex 3-dimensional shape and adequate size and demonstrate biomechanical stability over time. A critical requirement is the ability to promote the formation of functional periodontal attachment between regenerated alveolar bone, and newly formed cementum on the root surface. This review outlines the current advances in multiphasic scaffold fabrication and how these scaffolds can be combined with cell- and growth factor–based approaches to form tissue-engineered constructs capable of recapitulating the complex temporal and spatial wound-healing events that will lead to predictable periodontal regeneration. This can be achieved through a variety of approaches, with promising strategies characterized by the use of scaffolds that can deliver and stabilize cells capable of cementogenesis onto the root surface, provide biomechanical cues that encourage perpendicular alignment of periodontal fibers to the root surface, and provide osteogenic cues and appropriate space to facilitate bone regeneration. Progress on the development of multiphasic constructs for periodontal tissue engineering is in the early stages of development, and these constructs need to be tested in large animal models and, ultimately, human clinical trials.

    Full Text Available Alzheimer's disease is the preeminent cause and commonest form of dementia. It is clinically characterized by a progressive descent in the cognitive function, which commences with deterioration in memory. The exact etiology and pathophysiologic mechanism of Alzheimer's disease is still not fully understood. However it is hypothesized that, neuroinflammation plays a critical role in the pathogenesis of Alzheimer's disease. Alzheimer's disease is marked by salient inflammatory features, characterized by microglial activation and escalation in the levels of pro-inflammatory cytokines in the affected regions. Studies have suggested a probable role of systemic infection conducing to inflammatory status of the central nervous system. Periodontitis is common oral infection affiliated with gram negative, anaerobic bacteria, capable of orchestrating localized and systemic infections in the subject. Periodontitis is known to elicit a "low grade systemic inflammation" by release of pro-inflammatory cytokines into systemic circulation. This review elucidates the possible role of periodontitis in exacerbating Alzheimer's disease. Periodontitis may bear the potential to affect the onset and progression of Alzheimer's disease. Periodontitis shares the two important features of Alzheimer's disease namely oxidative damage and inflammation, which are exhibited in the brain pathology of Alzheimer's disease. Periodontitis can be treated and hence it is a modifiable risk factor for Alzheimer's disease.

  7. Association between Hypertension and Periodontitis: Possible Mechanisms

    This review is to examine the current literatures on the relationship between periodontitis and hypertension as well as to explore the possible biological pathways underlying the linkage between these health conditions. Hypertension is one of the major risk factors for cardiovascular diseases. Oxidative stress and endothelial dysfunction are among the critical components in the development of hypertension. Inflammation has received much attention recently and may contribute to a pivotal role in hypertension. Periodontitis, a chronic low-grade inflammation of gingival tissue, has been linked to endothelial dysfunction, with blood pressure elevation and increased mortality risk in hypertensive patients. Inflammatory biomarkers are increased in hypertensive patients with periodontitis. Over the years, various researches have been performed to evaluate the involvement of periodontitis in the initiation and progression of hypertension. Many cross-sectional studies documented an association between hypertension and periodontitis. However, more well-designed prospective population trials need to be carried out to ascertain the role of periodontitis in hypertension. PMID:24526921

    Radiographs are a well-accepted tool in diagnosing periodontal bone lesions and making an accurate evaluation of the treatment. However, the assessment of bone is hampered by the complicated and as it were unpredictable pattern of bone structure. Therefore, and to compensate for the bias always present in human observations, a computer aided procedure was developed to detect and describe periodontal bone lesions. This paper describes a comparison of the performance by human observers and of the computer program. Two series of artificial periodontal bone lesions served as material for the assessments. This study shows that the automated lesion detection program enables an assessment of periodontal bone lesions, which is at least comparable with the results of a group of experienced observers and probably better. It is considerably better than the results of observers individually, and decreases the time-dependent variability appearing in repeated assessments of a single observer. The computer aided detection of periodontal lesions can be considered as a useful and reliable tool in periodontal diagnosis. 9 ref.; 2 figs

    New products and treatment modalities for the management of periodontal disease continue to offer the clinician a large number of choices, many of which involve antimicrobials. Specific pathogenic bacteria play a central role in the etiology and pathogenesis of destructive periodontal disease. Under suitable conditions, periodontal pathogens colonize the subgingival environment and are incorporated into a tenacious biofilm. Successful prevention and treatment of periodontitis is contingent upon effective control of the periodontopathic bacteria. This is accomplished by professional treatment of diseased periodontal sites and patient-performed plaque control. Attention to community factors, such as water contamination and bacterial transmission among family members, facilitates preventive measures and early treatment for the entire family. Subgingival mechanical debridement, with or without surgery, constitutes the basic means of disrupting the subgingival biofilm and controlling pathogens. Appropriate antimicrobial agents that can be administered systemically (antibiotics) or via local delivery (povidone-iodine) may enhance eradication or marked suppression of subgingival pathogens. Microbiological testing may aid the clinician in the selection of the most effective antimicrobial agent or combination of agents. Understanding the benefits and limitations of antibiotics and antiseptics will optimize their usefulness in combating periodontal infections.

    These case series were aimed at highlighting late presentations of aggressive periodontitis (AP) in a teaching hospital as well as proffering possible reasons for such presentations which would serve as part of the solution to prevent such presentations in the future. Aggressive periodontitis is a severe form of destructive periodontitis traditionally believed to present around puberty. However, many cases seen in a teaching hospital presented much later for yet-to-be explained reasons. Seven patients referred to the specialist periodontal clinic of a Nigerian teaching hospital presented with clinical features consistent with AP. Most of the patients were over twenty and some over thirty years of age. Aggressive periodontitis patients seen in our center were often outside the traditional age brackets. The range of treatment options available to the patients were under-utilized due to serious financial constraints. Aggressive periodontitis comes with serious psychological challenges and severe morbidity. Prompt diagnosis and effective management hold the key to success It is important to investigate why many of the cases seen in our center presented that late. Could be due to ignorance and poverty or could be due to failure of dentists recognize these cases and consequent misdiagnosis? Further studies are needed to answer these questions.

    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.

    2015-01-01

    Full Text Available Dental anatomy is quite complex and diverse factors must be taken into account in its analysis. Teeth with anatomical variations present an increase in the rate of severity periodontal tissue destruction and therefore a higher risk of developing periodontal disease. In this context, this paper reviews the literature regarding enamel pearls and their implications in the development of severe localized periodontal disease as well as in the prognosis of periodontal therapy. Radiographic examination of a patient complaining of pain in the right side of the mandible revealed the presence of a radiopaque structure around the cervical region of lower right first premolar. Periodontal examination revealed extensive bone loss since probing depths ranged from 7.0 mm to 9.0 mm and additionally intense bleeding and suppuration. Surgical exploration detected the presence of an enamel pearl, which was removed. Assessment of the remaining supporting tissues led to the extraction of tooth 44. Local factors such as enamel pearls can lead to inadequate removal of the subgingival biofilm, thus favoring the establishment and progression of periodontal diseases.

    Nuclear factor of activated T-cells (NFAT) and NF-kB pathway associated processes are involved in the pathogenesis of various inflammatory disorders, for example, periodontal disease. The activation of these pathways is controlled by the regulator of calcineurin 1 (RCAN1). The aim of this study was to elucidate the role of RCAN1 in periodontal disease. Healthy and inflamed periodontal tissues were analyzed by immunohistochemistry and immunofluorescence using specific rabbit polyclonal anti-RCAN1 antibodies. For expression analysis human umbilical vein endothelial cells (HUVEC) were used. HUVEC were incubated for 2 h with Vascular Endothelial Growth Factor (VEGF) or with wild type and laboratory strains of Porphyromonas gingivalis (P. gingivalis). Expression analysis of rcan1 and cox2 was done by real time PCR using specific primers for rcan1.4 and cox2. The expression of rcan1 was found to be significantly suppressed in endothelial cells of chronically inflamed periodontal tissues compared to healthy controls. Rcan1 and cox2 were significantly induced by VEGF and wild type and laboratory P. gingivalis strains. Interestingly, the magnitude of the rcan1 and cox2 induction was strain dependent. The results of this study indicate that RCAN1 is suppressed in endothelial cells of chronically inflamed periodontal tissues. During an acute infection, however, rcan1 seems to be upregulated in endothelial cells, indicating a modulating role in immune homeostasis of periodontal tissues.

    Investigations about possible correlations between vegetarian diet and periodontal conditions are rare and characterized by small case numbers. The aim of this clinical study was to investigate the influence of a vegetarian diet on periodontal parameters with an appropriate sample size. A total of 200 patients, 100 vegetarians and 100 non-vegetarians, were included in the study. All patients were examined including a full mouth assessment of the periodontal and dental conditions. In addition, a questionnaire was handed out to ask for patients' oral hygiene habits and level of education. For statistical analysis the Mann-Whitney Test (χ(2) for analysis of the questionnaire) was applied (level of significance: Pvegetarians versus 41.72 years non-vegetarians). Vegetarians had significantly lower probing pocket depths (P=0.039), bleeding on probing (P=0.001), periodontal screening index (P=0.012), a better hygiene index (Pvegetarians. Furthermore, vegetarians had a higher level of education (PVegetarians revealed better periodontal conditions (less inflammation signs, less periodontal damage and a better dental home care). However, it should be considered that vegetarians are not only avoiding meat in their nutrition but are also characterized by an overall healthier life style.

    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.

    to verify the association of osteoporosis with periodontal disease. the study has included 39 postmenopausal women divided in three groups according to bone mass categories, through evaluation of mineral bone density (MBD), measured by X-ray double emission absorbimetry in the lumbar area (L1-L4): ): normal bone; osteopenia and osteoporosis. In all the participants the Clinical Insertion Level (CIL) index has been determined at the research onset and after one year, by the same examiner. The periodontal situation data have been submitted to statistical analysis with the paired t-Student test. the periodontal exam has shown that postmenopausal women in the osteopenia presented lower CIL at the initial periodontal clinical exam (2.1+/-1.1 mm), while the ones in the normal bone showed less teeth support tissue loss after one year (3.1+/-1.6 mm). The statistical analysis has shown that there was no significant difference for the periodontal situation in the normal bone, but there was significant statistical difference for the osteopenia and osteoporosis patients, when CIL values from both evaluation periods were compared. it is concluded that postmenopausal osteoporosis may be a possible risk factor for periodontal disease.

    Full Text Available Background and Aim: It has been suggested that osteoporosis may be a predisposing factor for periodontitis and tissue destruction, thus periodontitis and mandibular bone density might be related. The purpose of the present study was to evaluate the clinical signs of periodontal tissue destruction in postmenopausal women. Materials and Methods: In this cross-sectional study, 60 postmenopausal women (51 to 78 years of age underwent radiographic examination of the right mandibular premolar. Mandibular bone density (MBD was measured using optical densitometry. Periodontal status variables examined included: probing pocket depth (PPD, clinical attachment level (CAL, bleeding on probing (BOP and plaque index (PLI. Data were analyzed by statistical tests using P<0.05 as the limit of significance. Results: This study found no statistically significant association between the four indicators of periodontal disease and mandibular bone density, but there was statistically significant association between mandibular bone density and the number of remaining teeth. There was also statistically significant association between PPD and the number of remaining teeth. Conclusion: These findings suggest that individuals with high MBD seem to retain teeth with deep periodontal pockets more easily than those with lower MBD.

    Many middle aged and old persons take periodontal diseases that mainly cause teeth loss and result in some systemic diseases. The prevention of periodontal diseases is very important for oral and systemic health, but the present diagnostic examination is not fully objective and suitable. To diagnose periodontal diseases exactly, some biomarkers shown inflammation, tissue degradation and bone resorption, in gingival crevicular fluid (GCF) and saliva are known. We demonstrated that GCF levels of calprotectin, inflammation-related protein, and carboxy-terminal propeptide of type I procollagen, bone metabolism-related protein, were associated with clinical condition of periodontal diseases, and suggested that these proteins may be useful biomarkers for periodontal diseases. Recently, determinations of genes and proteins by using microdevices are studied for diagnosis of some diseases. We detected calprotectin protein by chemiluminescent immunoassay on a microchip and showed the possibility of specific and quantitative detection of calprotectin in a very small amount of GCF. To determine plural markers in GCF by using microdevices contributes to develop accurate, objective diagnostic system of periodontal diseases.

    2007-09-01

    This article reviews the available studies assessing the association between chronic inflammatory periodontal diseases with atherosclerosis-induced diseases, cardiovascular diseases, and their complications, using standard evidence based criteria. This study is based on a literature search using Medline medical database covering the period from 2001 to April 2006 and applying specific inclusion criteria. The authors reviewed randomized controlled trials, systematic reviews, narrative reviews and meta-analyses, which investigated the relationship of periodontal and cardiovascular diseases with clinically derived documentation. The critical evaluation of the studies was performed based on the Impact Factor of the journals, on which they were published. On the basis of clinical aspects, the periodontitis-cardiovascular association was evaluated in 2 randomized controlled trials, 5 systematic reviews, 5 narrative reviews and 2 meta-analyses. The evidence linking periodontitis with an increased risk for cardiovascular disease and atherosclerosis is limited. Current evidence supporting the causal, periodontitis-cardiovascular disease, association is weak. There is a clear need for new, well designed observational and intervention studies to confirm that thus far observed associations explore the validity of the associations in diverse populations, to establish whether they are causal in nature and determine potential benefits of periodontal intervention in reducing the risk for these medical conditions.

    2016-01-01

    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.

    During HIV infection different lesions may occur in the area of the gingiva and/or the periodontium. An increased frequency and severity of periodontal diseases has been observed. Different forms of Candida albicans infection have been clinically characterized as pseudomembranous, erythematous (atrophic) or hyperplastic form or as papillary variant. While infection with Candida albicans may occur frequently in other areas of the oral mucosa, candidiasis of the gingiva seems to be quite rare. Due to the underlying immunodeficiency, HIV-infected patients are prone to infection with and/or reactivation of different viruses, which may cause oral lesions as well. Recurrent progressive ulcerations may occur due to herpes simplex virus 1/2, while ulcerations with a punched-out appearance may result from disseminated CMV infection. Oral Kaposi's sarcoma may clinically present as bluish or red spots, which may increase into exophytic tumors during the progress of the disease.

    Periodontal disease is a family of chronic inflammatory conditions caused by bacterial infections.' It is manifested in red, swollen gingiva (gums) and can lead to destruction of the connective tissue and bone that hold teeth in place. Conventional treatments typically require some form of invasive surgery, depending on the disease stage at time of detection. Photodynamic Therapy (PDT) is the use of light-activated drugs (photosensitizers) for treatment of a variety of conditions 2 such as solid tumors, pre-malignancies, macular degeneration and actinic keratitis. There have been a number of studies of PDT as an antibacterial agent. 3'4 Depending on the photosensitizer and strain of bacteria, significant killing (several LOGS) can be achieved.

    Full Text Available Chronic periodontitis is the most common type of periodontitis and it is associated with various species of microorganisms. Enteric rods, Pseudomonas, Staphyloccocus and Candida have been retrieved from periodontal pockets of patients with chronic periodontitis and correlated to cases of superinfection. Local or systemic antibiotic therapy is indicated to reinforce the effects of the conventional mechanical therapy. Minocycline has been suggested as one of the most effective drugs against periodontal pathogens. The aim of this work was to evaluate the minimal inhibitory concentration (MIC of minocycline on superinfecting microorganisms isolated from the periodontal pocket and the oral cavity of individuals with chronic periodontitis. Isolates of Enterobacteriaceae (n = 25, Staphylococcus spp. (n = 25, Pseudomonas aeruginosa (n = 9 and Candida spp. (n = 25 were included in the study. Minimal inhibitory concentrations (MIC of minocycline were determined using the Müeller-Hinton agar dilution method. Staphylococcus spp. isolates were the most sensitive to minocycline with a MIC of 8 µg/mL, followed by Enterobacteriaceae with a MIC of 16 µg/mL. The concentration of 16 µg/mL inhibited 96% of Candida spp. isolates. The MIC for 88.8% of the isolates of Pseudomonas aeruginosa was 128 µg/mL. A concentration of 1,000 µg/mL was not enough to inhibit 100% of the tested isolates.Periodontite crônica é a forma mais comum de periodontite e está associada a diversas espécies de microrganismos. Enterobactérias, Pseudomonas, Staphyloccocus e Candida têm sido recuperados de bolsas periodontais de indivíduos com periodontite crônica e implicados em casos de superinfecção. A terapia antimicrobiana local ou sistêmica pode ser utilizada para reforçar os efeitos da terapia mecânica convencional, e a minociclina tem sido sugerida como antimicrobiano eficaz frente a periodontopatógenos.

A partir do primeiro ano de governo do presidente Lula (2003, o Brasil enfatiza esta forma de política social, ao unificar diferentes modelos de transferência do governo anterior (1995-2002 em um só programa: o Bolsa Família. O artigo em questão busca expor a crítica da regulação da pobreza e o impacto das condicionalidades referentes a esta lógica de intervenção na reprodução social de um grupo específico. A relação entre o Estado e as mulheres – responsáveis únicas pelo sustento financeiro de suas casas e, majoritariamente, as maiores beneficiárias destes programas – é caracterizada por atravessamentos em termos de classe social, gênero e raça. Ao apresentar a perspectiva feminista, o artigo procura abrir uma série de questões ao analisar como as condicionalidades impostas pelo Programa Bolsa Família tendem a naturalizar o papel reprodutivo das mulheres na sociedade brasileira, limitando seu espaço de agenciamento e emancipação

    Full Text Available Abstract The purpose of this cross-sectional study was to investigate the effect of different forms of periodontal diseases on Oral Health-Related Quality of Life (OHRQoL. Fifty-two patients with Aggressive Periodontitis (AP or Chronic Periodontitis (CP were included: nine patients with Localized Aggressive Periodontitis (LAP, thirty-three patients with Generalized Aggressive Periodontitis (GAP and ten patients with Generalized Chronic Periodontitis (GCP. Oral Health Impact Profile questionnaires (OHIP-14 were distributed after a clinical examination that measured the following periodontal parameters: tooth loss, bleeding on probing (BoP, probing depth (PD, gingival recession (REC and clinical attachment level (CAL. The global OHIP-14 score means were 10.6 for LAP, 16.5 for GAP, and 17.5 for GCP. A statistically significant difference (p < 0.01 was observed between the LAP group and the other two groups. There was significantly less bleeding and recession in the LAP group than in the patients with the generalized forms of periodontitis. LAP, GAP and GCP have an impact on patient quality of life when measured using the OHIP-14. Patients with GAP and GCP had poorer OHRQoL than LAP patients.

    It has been claimed that periodontal dressing reduces the risk of wound infection, bleeding and granulation tissue formation and improves tissue healing. This study sought to assess the effect of periodontal dressing on wound healing and patient satisfaction following periodontal flap surgery. This clinical trial was conducted on 33 patients presenting to Hamadan University, School of Dentistry in 2012 whose treatment plan included two periodontal surgical procedures on both quadrants of the maxilla or mandible. The variables evaluated were severity of pain, bleeding, facial swelling and ease of nutrition experienced by patient during the first 3 days after surgery and inflammation, granulation tissue formation and gingival color at 7 and 14 days. Obtained data were analyzed using SPSS version 16.0 and R software and chi-square and t-tests. The mean (±SD) pain score was 1.73±1.153 and 2.79±1.933 in surgical sites with and without periodontal dressing, respectively and this difference was statistically significant (P=0.005). No significant difference was noted between sites with and without periodontal dressing in terms of swelling, bleeding, gingival consistency, granulation tissue formation, gingival color and ease of nutrition (P>0.05). According to the results of the present study, patients did not experience more bleeding, facial swelling or nutritional problems without periodontal dressing; however, the level of pain experienced was lower after surgeries with the use of periodontal dressing.

    Periodontitis shares several clinical and pathogenic characteristics with chronic arthritis, and there is some degree of coexistence. The aims of this study were to elucidate whether patients with localized aggressive periodontitis (LAgP), generalized aggressive periodontitis (GAgP), juvenile idiopathic arthritis (JIA), and rheumatoid arthritis (RA) share periodontal and hematological characteristics distinguishing them from individuals free of diseases. The study population consisted of white adults (or=4 mm, CAL>or=2 mm, and ABL>or=2 mm compared to controls. The percentage of sites with CAL>or=2 mm significantly correlated with the levels of IgM-RF and IgA-RF. Missing teeth in JIA and RA patients were not lost due to periodontitis. Patients with GAgP showed higher levels of leukocytes, including neutrophils, and CRP compared to controls. In part, JIA and RA patients showed similar results. Young adults with RA may develop periodontal destruction, and these patients require professional attention. Both differences and similarities in periodontal and hematological variables were seen in individuals with periodontitis, JIA, and RA.

    A systematic review of clinical trials has been performed to evaluate the reproducibility of manual (MP) and electronic probes (EP) in the measurement of clinical periodontal attachment level (AL) in untreated periodontitis subjects. Systematic electronic (PubMed Medline and Latin American and Caribbean Health Science--LILACS literature databases) and hand searches (English, Spanish and Portuguese languages; search terms "periodontitis diagnosis", "clinical attachment level measurements", "clinical attachment level detection", "clinical diagnosis of periodontitis", "manual probe", "electronic probe", "periodontitis or periodontal disease or attachment level or clinical attachment level") were performed to identify clinical trials involving CAL measurements, MP and EP in untreated periodontitis subjects. Quality and external validity were determined for selected studies. The initial search identified 37 articles. Ten studies met the initial eligibility, but eight were excluded after thorough analysis. The results from those two selected studies showed that the average variance and the absolute mean difference of CAL measurements for both types of probes cannot be considered different. "Based on this systematic review, MP and EP probes showed a tendency to have similar reliability in the measurement of CAL in untreated periodontitis subjects when used by a calibrated examiner. However, this finding is not supported by strong evidence.

    Gingivitis and chronic periodontitis are highly prevalent chronic inflammatory diseases. Gingivitis affects the majority of people, and advanced periodontitis is estimated to affect 5-15% of adults. The detection and diagnosis of these common diseases is a fundamentally important component of oral health care. All patients should undergo periodontal assessment as part of routine oral examination. Periodontal screening using methods such as the Basic Periodontal Examination/Community Periodontal Index or Periodontal Screening Record should be performed for all new patients, and also on a regular basis as part of ongoing oral health care. If periodontitis is identified, full periodontal assessment is required, involving recording of full mouth probing and bleeding data, together with assessment of other relevant parameters such as plaque levels, furcation involvement, recession and tooth mobility. Radiographic assessment of alveolar bone levels is driven by the clinical situation, and is required to assess bone destruction in patients with periodontitis. Risk assessment (such as assessing diabetes status and smoking) and risk management (such as promoting smoking cessation) should form a central component of periodontal therapy. This article provides guidance to the oral health care team regarding methods and frequencies of appropriate clinical and radiographic examinations to assess periodontal status, to enable appropriate detection and diagnosis of periodontal conditions.

    To evaluate the effectiveness of community periodontal care intervention in type 2 diabetic patients with chronic periodontitis who participated in community non-communicable diseases management service. The randomized controlled and blinded community trial with a duration of six months was designed to compare effects of "periodontal initial therapy" on group I(22 cases), of "professional mechanical tooth cleaning (PMTC), i.e. coronal scaling" on group II(19 cases)and of "non-clinical therapy" on the control group(25 cases). The clinical periodontal indexes, such as probing depth (PD), attachment loss (AL), modified bleeding index (mBI), plaque index (PLI) were obtained with a Williams type periodontal probe; Laboratory examinations including glycosylated haemoglobin A1(HbA1C), glucose assay, were conducted. The reductions of PD in groups I and II were 0.71 and 0.70 mm, respectively, which was more significant than in control group (0.20 mm); the reductions of AL in groups I, II, and control group were 0.86, 0.57, and 0.03 mm, respectively, which showed significance in all the three groups. The subjects of groups I and II had 0.56% and 1.01% reductions of HbA1C respectively, and the significance was observed in group II. In addition, the improvement of HbA1C values in group II was highly correlated with the decrease in gingivitis (r=0.51, P=0.03). The community periodontal care approaches implemented in the community health service centers have significantly improved periodontal health as well as reduced glycemic level, which could be regarded as basic health care strategies for the patients with diabetes.

    Here we report a case of generalized aggressive periodontitis treated with periodontal therapy including adjunct antimicrobial therapy and periodontal surgery. The patient was a 22-year-old woman who presented with the chief complaint of gingival recession. Baseline examination revealed generalized plaque deposition and gingival inflammation. Thirty-nine percent of the sites had a probing depth (PD) of 4-6 mm and 2% a PD of ≥7 mm; 63% exhibited bleeding on probing (BOP). Radiographic examination revealed vertical bone loss in the molars and horizontal bone loss in other teeth. Microbiological examination of subgingival plaque revealed the presence of Aggregatibacter actinomycetemcomitans and Tannerella forsythia. Oral health-related quality of life was assessed as a measure of patient-reported outcome. Based on a clinical diagnosis of generalized aggressive periodontitis, initial periodontal therapy and adjunct antimicrobial therapy were implemented. After reducing inflammation and subgingival bacteria, open flap debridement was performed for teeth with a PD of ≥4 mm. Reevaluation showed no sites with a PD of ≥5 mm, a minimal level of BOP, and a marked reduction in the level of the targeted periodontal pathogens. The patient's oral health-related quality of life was slightly worsened during supportive periodontal therapy (SPT). Implementation of adjunct antimicrobial therapy targeting periodontal pathogens and subsequent periodontal surgery resulted in improvement in periodontal and microbiological parameters. This improvement has been adequately maintained over a 2-year period. However, additional care is necessary to further improve the patient's oral health-related quality of life during SPT.

    Full Text Available Biomarkers are highly specific and sensitive indicators of disease activity. Resistin is a recently discovered adipocytokine, having a potent biomarker quality. Initially resistin was thought to be produced by adipocytes alone; however, emerging evidence suggests that it is also produced in abundance by various cells of the immunoinflammatory system, indicating its role in various chronic inflammatory diseases. Data suggests that resistin plays a role in obesity, insulin resistance, cardiovascular diseases, and periodontitis. Resistin derived its name from the original observation that it induced insulin resistance (resist-in: resist insulin in mice and is downregulated in mature murine adipocytes cultured in the presence of insulin sensitizing drugs like thiazolidinediones. It is well recognized that obesity, is associated with insulin resistance and diabetes. A three-way relationship has been established between diabetes, obesity and periodontitis. Recent evidence also suggests an association between obesity and increased risk for periodontitis. Our previous research showed incremental elevation of resistin with periodontal disease activity and a reduced level of resistin, after periodontal therapy. Thus resistin would be one of the molecular links connecting obesity, periodontitis, and diabetes and may serve as a marker that links periodontal disease with other systemic diseases. A Medline/PubMed search was carried out for keywords “Diabetes Mellitus,” “Periodontitis,” and “Resistin,” and all relevant research papers from 1990 in English were shortlisted and finalized based on their importance. This review provides an insight into the biological action of resistin and its possible role in periodontitis influenced diabetes mellitus and diabetes induced periodontitis.

    Bacterial invasion of the periodontal tissues has been suggested as a relevant step in the etiopathogenesis of periodontal disease. However, its exact importance remains to be defined. The present systematic review assessed the scientific evidence concerning the relationship between the quality or quantity of periodontal microbiota in periodontal tissues and development of periodontal disease. The databases Medline-PubMed, Cochrane-CENTRAL, ISI Web of Knowledge and SCOPUS were searched, up to January 2014. Studies that reported evaluation of periodontal pathogens invasion on human tissues were selected. The screening of 440 title/abstracts elected 26 papers for full-text reading. Twenty three papers were subsequently excluded because of insufficient data or a study protocol not related to the objectives of this systematic review. All included studies were case-control studies that evaluated intracellular or adherent bacteria to epithelial cells from periodontal pockets versus healthy sulci. Study protocols presented heterogeneity regarding case and control definitions and methodological approaches for microbial identification. No consistent significant differences were found related to the presence/absence or proportion of specific periopathogens across the studies, as only one study found statistically significant differences regarding the presence of A. actinomycetemcomitans (p = 0.043), T. forsythia (P < 0.001), P. intermedia (P < 0.001), C. ochracea (P < 0.001) and C. rectus (P = 0.003) in epithelial cells from periodontal pockets vs. healthy sulci. All studies reported a larger unspecific bacterial load in or on the epithelial cells taken from a diseased site compared to a healthy sulcus. The current available data is of low to moderate quality and inconsistent mainly due to study design, poor reporting and methodological diversity. As so, there is insufficient evidence to support or exclude the invasion by periodontal pathogens as a key step in the

    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

    A relationship between periodontal disease and atherosclerosis has been suggested by epidemiological studies. Ligature-induced experimental periodontitis is an adequate model for clinical periodontitis, which starts from plaque accumulation, followed by inflammation in the periodontal tissue. Here we have demonstrated using a ligature-induced periodontitis model that periodontitis activates monocytes/macrophages, which subsequently circulate in the blood and adhere to vascular endothelial cells without altering the serum TNF-α concentration. Adherent monocytes/macrophages induced NF-κB activation and VCAM-1 expression in the endothelium and increased the expression of the TNF-α signaling cascade in the aorta. Peripheral blood-derived mononuclear cells from rats with experimental periodontitis showed enhanced adhesion and increased NF-κB/VCAM-1 in cultured vascular endothelial cells. Our results suggest that periodontitis triggers the initial pathogenesis of atherosclerosis, inflammation of the vasculature, through activating monocytes/macrophages. PMID:24893991

    The periodontal pocket, one of the definitive signs of periodontal disease, is the most common parameter to be assessed by dental clinicians. Periodontal probes have been the instruments most commonly used to locate and measure these pockets. Regular use of periodontal probes in routine dental practice facilitates and increases the accuracy of the process of diagnosing the condition, formulating the treatment, and predicting the outcome of therapy. Advances in the field of periodontal probing have led to the development of probes that may help reduce errors in determining this parameter used to define the state of active periodontal disease. One such advance is the emergence of probes that purportedly assess periodontal disease activity noninvasively. The selection of periodontal probe depends on the type of dental practice: a general dental practitioner would require first- or second-generation probes, while third- through fifth-generation probes generally are used in academic and research institutions as well as specialty practices.

    This article is a traditional literature review on caries levels in aggressive periodontitis. Aggressive periodontitis generally affects systemically healthy individuals aged aggressive periodontitis has long been debated. Initial research indicated that caries levels were high in patients with aggressive periodontitis, but high-quality studies have consistently shown that caries and aggressive periodontitis are inversely related. A recent in vitro study showed that Streptococcus mutans was killed more readily in the saliva of patients with aggressive periodontitis and Aggregatibacter actinomycetemcomitans positivity than in patients with A. actinomycetemcomitans negativity. Other mechanisms possibly explaining the inverse relationship between caries and aggressive periodontitis in cases of Down's syndrome are also discussed in this literature review. The usefulness of caries level in the diagnosis of aggressive periodontitis in developing countries such as India, where the disease is diagnosed primarily on the basis of clinical and radiographic features and familial history is also discussed.

    To evaluate neutrophil myeloperoxidase (MPO) staining procedure as a reliable, affordable and easily available diagnostic assay for aggressive periodontitis. Fifteen subjects were recruited in the study wherein five each were diagnosed as aggressive periodontitis and chronic periodontitis respectively, and five were periodontally healthy. Three millilitres (ml) of venous blood was collected using Vacutainers containing ethylene diamine tetra acetate (EDTA) and was subjected to MPO staining procedure. Histological picture was evaluated using a visual analogue scale (VAS). MPO stained specimen of all the patients showed positive MPO staining of the neutrophils. The intensity of the stain of MPO granules was more in aggressive periodontitis specimen as compared to the chronic periodontitis patient specimen and healthy subject specimen. The staining characteristics were comparable for chronic periodontitis patients and healthy subject. This study shows that there is a potential and probable place for MPO staining as an economical, relatively convenient and easily available assay in the diagnosis of aggressive periodontitis.

    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.

    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.

    Full Text Available Background/Aim. Diabetes mellitus (DM as a complex metabolic disease influences functioning of numerous organs. Therefore, frequent diabetic complication is chronic periodontitis. The aim of the study was to investigate the influence of various risk factors, like age, sex, duration of DM, oral hygiene, on oral manifestations of diabetes. Methods. The group of diabetics included 52 adult patients, 18-79-year of age, both sexes (33 females, 19 males out of which 35 patients were with diabetes mellitus type I and 17 with type II. Mean age of the patients was 54.6 years and the mean duration of diabetes was 11.1 years. The controls consited of 67 volunteers from the city of Belgrade, 19-24-year of age, both sexes (47 females, 20 males with no paradonthopathy and non-systemic diseases. Estimation of periodontal status of the patients was performed by measuring dental plaque index, gingival index and periodontal pockets' depth. Results. The results suggest an increased incidence and severity of periodontitis in diabetic patients. It was established that duration of diabetes, patients' age and bad oral hygiene had a negative influence on status of remained teeth in diabetics, while the sex had no influence on parameters monitored. Conclusion. Indices of oral hygiene level and periodontal status (dental plaque index, gingival index and periodontal pockets' depth were significantly worsened in patients with diabetes. Negative influence on remained teeth had patients' age (>50 years, duration of diabetes (> 20 years and bad oral hygiene. About half of the patients had a total or partial bridge suggesting that periodontitis is significant complication of diabetes mellitus.

  18. Aggressive periodontitis: case definition and diagnostic criteria.

    Science.gov (United States)

    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 Background. Periodontal therapy for treatment of periodontitis involves the elimination of anatomic defect. There are two primary approaches to eliminating these anatomic defects : resective (gingivectomy, osseous resection, and apically positioned flaps, and regenerative surgery (osseous graft, guided tissue regeneration, resorbable barriers, coronally position flaps. Aims. The dentist know the outcomes after periodontal surgery. References. Periodontal regeneration means healing after periodontal surgery that results in the formation of a new attachment apparatus, consisting of cementum, periodontal ligament, and alveolar bone. Periodontal repair implies healing without restoration of the normal attachment apparatus. Histologic evaluation is the only reliable method to determine the true efficacy of periodontal therapies. Discussion. The variables involved in periodontal wound healing to solve how to achieve periodontal regeneration are manipulation of progenitor cell, alteration of pathologically exposed root surfaces, exclusion of gingival epithelium, and wound stabilization. Conclusions. Periodontal surgery usually do not result in periodontal regeneration. Gingival epithelium that proliferates apically can be inhibited by stabilization of the flap margin and regenerative surgery.

    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.

    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

    Full Text Available Este trabalho teve como objetivo analisar o empoderamento das mulheres beneficiárias do Programa de Transferência de Renda, conhecido como "Programa Bolsa Família", na percepção dos agentes sociais dos Centros de Referência de Assistência Social (Cras. Para tanto, realizou-se um estudo de caso múltiplo, tendo como sujeitos de pesquisa 11 gestores de diferentes Cras do estado de Minas Gerais. A partir da técnica de análise de conteúdo, as respostas das perguntas, que compuseram as entrevistas, foram agrupadas de acordo com as categorias Bolsa Família, Cras e Mulher. Os resultados apontam a importância do Cras na execução do Programa Bolsa Família e no processo de empoderamento, pois a convivência e a participação neste local têm contribuído para a conscientização sobre direitos, para a inserção social e para a melhoria do bem-estar das mulheres, fatores evidenciados por intermédio do interesse das mulheres por cursos, oficinas, informações sobre programas sociais e atendimento psicológico. Na percepção dos agentes, foi possível observar melhoria nas condições de vida, nas relações familiares, conscientização e autoestima, implicando reflexos sobre o empoderamento feminino. Portanto, embora sendo um processo lento e embrionário, pode-se dizer que o ciclo do empoderamento das mulheres beneficiárias do Bolsa Família pode ser completado, pois consegue atingir as três dimensões (individual, familiar e comunitária.

    Full Text Available Introduction: Bacterial plaque has been identified as the primary factor for the onset of periodontal disease. Although pathogens are very important in the pathogenesis of periodontal diseases, the hosts’ systemic and predisposing factors should also be considered. Sex hormones are important factors contributing to periodontal diseases. The purpose of this study was to investigate the effects of menstruation cycle on periodontal indices. Materials & Methods: In this study, 20 premenopausal women (17-45 years old were selected. Before the examination, scaling and oral health instruction for all subjects was done. Clinical examinations were done during the menstrual cycle specifically during ovulation (OV time, during pre-menstruation (PM and during menstruation (M with four month in tervals.

    Full Text Available Evidence for the link between periodontal disease and several systemic diseases is growing rapidly. Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life causing morbidity and mortality. Periodontitis, one of these complications, is a chronic infection associated with substantial morbidity in the form of tooth loss and that affects the quality of life directly. The association between diabetes and inflammatory periodontal disease has been studied extensively. The relationship between these two conditions appears bidirectional. The presence of one condition tends to promote the other and the meticulous management of either may assist treatment of the other. It also provides a perfect example of a cyclical association, whereby a systemic disease predisposes the individual to oral infections, and once the oral infection is established, it exacerbates the systemic disease. This review focuses to explain the interrelationship between the two based on information in the literature and the potential common immunoregulatory connections involved, exploring the mechanisms through which periodontal infection can contribute to the low-grade general inflammation associated with diabetes. Keywords: Diabetes mellitus; inflammation; insulin resistance; periodontitis.

    About 85-94% of the Spanish adults older than 35 experience gum problems, and about 15-30% suffer from periodontitis, being severe in up to 5-11% of them. Unlike other inflammatory conditions, periodontal disease rarely causes discomfort, or limits life or causes functional limitations until its advanced stages, when clinical signs and symptoms arise (gingival recession, pathological teeth migration, or mobility). Lack of knowledge about the disease, together with the idea that tooth loss is linked to ageing, frequently results in a late diagnosis, requiring extensive treatments with a worse prognosis. At Primary Care level, there is series of drugs have been related to periodontal disease (anticonvulsants, immunosuppressive drugs, and calcium channel blockers) as secondary effects, which vary as regards their frequency and severity depending of the amount of accumulated plaque. Stress and depression have also been reported to alter the immune response and to increase the inflammatory response as well as periodontal susceptibility. Certain systemic conditions, such as diabetes mellitus, cardiovascular disorders, respiratory diseases, as well as low-weight pre-term birth, have also been linked to periodontitis.

    2010-09-01

    For many years an association between the low bone density of osteoporosis and increased risk of periodontal bone loss has been suspected. In this review the relationship between osteoporosis and periodontal disease is considered. For this narrative review a very broad search strategy of the literature was developed using both PubMed and Scopus databases using the search words "perio" and "osteoporosis". The reference lists from the selected papers were also scanned and this provided an additional source of papers for inclusion. The inclusion/exclusion criteria, were also quite liberal with only those papers dealing with bisphosphonates and osteonecrosis of the jaws, osteoporosis in edentulous individuals, as well as those not written in English being excluded. The data available suggest that reduced bone mineral density is a shared risk factor for periodontitis rather than a causal factor. However, more prospective studies are required to fully determine what, if any, relationship truly exists between periodontitis and reduced bone mineral density. More prospective studies are required to determine what, if any, relationships exist between periodontal disease and reduced bone mineral density. © 2010 The Authors.

    Full Text Available Periodontitis in cattle is an infectious purulent progressive disease associated with strict anaerobic subgingival biofilm and is epidemiologically related to soil management at several locations of Brazil. This study aimed to detect Treponema species in periodontal pockets of cattle with lesions deeper than 5mm in the gingival sulcus of 6 to 24-month-old animals considered periodontally healthy. We used paper cones to collect the materials, after removal of supragingival plaques, and kept frozen (at -80°C up to DNA extraction and polymerase chain reaction (PCR using T. amylovorum, T. denticola, T. maltophilum, T. medium and T. vincentii primers. In periodontal pocket, it was possible to identify by PCR directly, the presence of Treponema amylovorum in 73% of animals (19/26, T. denticola in 42.3% (11/26 and T. maltophilum in 54% (14/26. Among the 25 healthy sites, it was possible to identify T. amylovorum in 18 (72%, T. denticola in two (8% and T. maltophilum in eight (32%. Treponema medium and T. vincentii were not detected over all 51 evaluated samples. The presence of Treponema amylovorum, T. maltophilum and, in particular, the widely recognized T. denticola in subgingival microflora brings an original and potencially important contribution in studies of the bovine periodontitis.

    Full Text Available Purpose. The aim of this study was to analyse the levels of interleukin-6 (IL-6 and interleukin-8 (IL-8 in gingival crevicular fluid (GCF of patients with chronic periodontitis prior to and following surgical and/or nonsurgical periodontal therapy for a period of 32 weeks. Methods. GCF samples were obtained from 24 nondiseased and 72 diseased sites of 12 periodontal patients prior to as well as at 6, 16, and 32 weeks following non-surgical and surgical periodontal therapy. IL-6 and IL-8 levels were determined by enzyme-linked immunosorbent assay (ELISA. Results. Periodontal treatment improved all clinical parameters. Both treatment modalities resulted in similar IL-6 as well as IL-8 levels. Mean IL-6 and IL-8 concentrations were significantly higher in non-diseased compared to diseased sites and increased significantly following treatment in diseased sites. Mean total amounts of IL-6 and IL-8 (TAIL-6, TAIL-8 did not differ significantly between diseased and nondiseased sites, while following therapy TAIL-8 levels decreased significantly. Conclusions. The data suggest that periodontal therapy reduced the levels of IL-8 in GCF. However, a strong relationship between IL-6, IL-8 amounts in GCF and periodontal destruction and inflammation was not found.

    The purpose of this study was to induce experimental periodontitis in rats previously fed diets containing arginine silicate inositol (ASI) complex and examine the biochemical, immunological, and radiological effects. Fifty two 8-week-old female Sprague Dawley rats were equally divided into four groups. The control group included those fed a standard rat diet with no operation performed during the experiment. The periodontitis, ASI I, and ASI II groups were subjected to experimental periodontitis induction for 11 days after being fed a standard rat diet alone, a diet containing 1.81 g/kg ASI complex, or a diet containing 3.62 g/kg ASI complex, respectively, for 8 weeks. Throughout the 11-day duration of periodontitis induction, all rats were fed standard feed. The rats were euthanized on the eleventh day, and their tissue and blood samples were collected. In the periodontitis group, elevated tissue destruction parameters and reduced tissue formation parameters were found, as compared to the ASI groups. Levels of enzymes, cytokines, and mediators associated with periodontal tissue destruction were lower in rats fed a diet containing ASI complex after experimental periodontitis. These results indicate that ASI complex could be an alternative agent for host modulation.

    Human periodontal ligament stem cells (hPDLSCs) transplantation represents a promising approach for periodontal regeneration; however, the cell source is limited due to the invasive procedure required for cell isolation. As human umbilical cord mesenchymal stem cells (hUCMSCs) can be harvested inexpensively and inexhaustibly, here we evaluated the regenerative potentials of hUCMSCs as compared with hPDLSCs to determine whether hUCMSCs could be used as new cell sources for periodontal regeneration. Methods The characteristics of hUCMSCs, including multi-differentiation ability and anti-inflammatory capability, were determined by comparison with hPDLSCs. We constructed cell aggregates (CA) using hUCMSCs and hPDLSCs respectively. Then hPDLSCs-CA and hUCMSCs-CA were combined with β-tricalcium phosphate bioceramic (β-TCP) respectively and their regenerative potentials were determined in a rat inflammatory periodontal defect model. Results hPDLSCs showed higher osteogenic differentiation potentials than hUCMSCs. Meanwhile, hUCMSCs showed higher extracellular matrix secretion and anti-inflammatory abilities than hPDLSCs. Similar to hPDLSCs, hUCMSCs were able to contribute to regeneration of both soft and hard periodontal tissues under inflammatory periodontitis condition. There were more newly formed bone and periodontal ligaments in hPDLSCs and hUCMSCs groups than in non-cell treated group. Moreover, no significant differences of regenerative promoting effects between hPDLSCs and hUCMSCs were found. Conclusion : hUCMSCs generated similar promoting effects on periodontal regeneration compared with hPDLSCs, and can be used as new cell sources for periodontal regeneration.

    The Centers for Disease Control and Prevention (CDC) has as one of its strategic goals to support and improve surveillance of periodontal disease. In 2003, the CDC initiated the CDC Periodontal Disease Surveillance Project in collaboration with the American Academy of Periodontology to address population-based surveillance of periodontal disease at the local, state, and national levels. This initiative has made significant advancements toward the goal of improved surveillance, including developing valid self-reported measures that can be obtained from interview-based surveys to predict prevalence of periodontitis in populations. This will allow surveillance of periodontitis at the state and local levels and in countries where clinical resources for surveillance are scarce. This work has produced standard case definitions for surveillance of periodontitis that are now widely recognized and applied in population studies and research. At the national level, this initiative has evaluated the validity of previous clinical examination protocols and tested new protocols on the National Health and Nutrition Examination Survey (NHANES), recommending and supporting funding for the gold-standard full-mouth periodontal examination in NHANES 2009 to 2012. These examinations will generate accurate estimates of the prevalence of periodontitis in the US adult population and provide a superior dataset for surveillance and research. Also, this data will be used to generate the necessary coefficients for our self-report questions for use in subsets of the total US population. The impact of these findings on population-based surveillance of periodontitis and future directions of the project are discussed along with plans for dissemination and translation efforts for broader public health use.

    What is the family history of periodontal disease and the prevalence of smoking status among patients with professionally diagnosed periodontitis? Are these factors related to extent and severity of periodontitis? Over a 10-year period, referred patients from a clinic for periodontology in the Netherlands were examined in a cross-sectional study. Patients received at the intake appointment a full-mouth periodontal examination. Data regarding family history of periodontitis and smoking status were recorded. A total of 5375 adult periodontitis patients were included in this study sample with a mean age of 50 years. The prevalence of smoking was 34% and 37% of the subjects had at least one parent or sibling with periodontitis. The chance to have severe periodontitis was higher if the patient was male, smoker or had a brother with periodontitis. Being male, smoker and having a parent with periodontitis were significantly associated with a larger extent of periodontitis. Within the investigated population familial aggregation, smoking status, age and gender are factors that were related to extent and severity of adult periodontitis. © 2016 John Wiley & Sons A/S.

    The direct cytotoxicity of sonic extracts (SE) from nine periodontal bacteria for human gingival fibroblasts (HGF) was compared. Equivalent dosages (in terms of protein concentration) of SE were used to challenge HGF cultures. The cytotoxic potential of each SE was assessed by its ability to (1) inhibit HGF proliferation, as measured by direct cell counts; (2) inhibit 3H-thymidine incorporation in HGF cultures; or (3) cause morphological alterations of the cells in challenged cultures. The highest concentration (500 micrograms SE protein/ml) of any of the SEs used to challenge the cells was found to be markedly inhibitory to the HGFs by all three of the criteria of cytotoxicity. At the lowest dosage tested (50 micrograms SE protein/ml); only SE from Actinobacillus actinomycetemcomitans, Bacteroides gingivalis, and Fusobacterium nucleatum caused a significant effect (greater than 90% inhibition or overt morphological abnormalities) in the HGFs as determined by any of the criteria employed. SE from Capnocytophaga sputigena, Eikenella corrodens, or Wolinella recta also inhibited cell proliferation and thymidine incorporation at this dosage; however, the degree of inhibition (5-50%) was consistently, clearly less than that of the first group of three organisms named above. The SE of the three other organisms tested (Actinomyces odontolyticus, Bacteroides intermedius, and Streptococcus sanguis) had little or no effect (0-10% inhibition) at this concentration. The data suggest that the outcome of the interaction between bacterial components and normal resident cells of the periodontium is, at least in part, a function of the bacterial species

    The term 'quorum sensing' describes intercellular bacterial communication which regulates bacterial gene expression according to population cell density. Bacteria produce and secrete small molecules, named autoinducers, into the intercellular space. The concentration of these molecules increases as a function of population cell density. Once the concentration of the stimulatory threshold is reached, alteration in gene expression occurs. Gram-positive and Gram-negative bacteria possess different types of quorum sensing systems. Canonical LuxI/R-type/acyl homoserine lactone mediated quorum sensing system is the best studied quorum sensing circuit and is described in Gram-negative bacteria which employ it for inter-species communication mostly. Gram-positive bacteria possess a peptide-mediated quorum sensing system. Bacteria can communicate within their own species (intra-species) but also between species (inter-species), for which they employ an autoinducer-2 quorum sensing system which is called the universal language of the bacteria. Periodontal pathogenic bacteria possess AI-2 quorum sensing systems. It is known that they use it for regulation of biofilm formation, iron uptake, stress response and virulence factor expression. A better understanding of bacterial communication mechanisms will allow the targeting of quorum sensing with quorum sensing inhibitors to prevent and control disease.

Realiza-se, ainda, uma análise de sensibilidade dos resultados obtidos a fim de se verificar a robustez do método à presença de variáveis não observadas, bem como à especificação do modelo de escore de propensão. Os resultados estimados sugerem um efeito positivo das transferências monetárias sobre o consumo das famílias pobres beneficiárias. O fato de os recursos serem prioritariamente destinados a despesas com alimentos, educação, produtos de higiene e vestuário em detrimento de itens como bebidas e cigarros, despesas diversas e bens duráveis significa que, em alguma medida, estes recursos estão sendo gastos de forma eficiente. É provável, também, que o aumento do consumo destas famílias eleve o seu nível de bem-estar, representando um "alívio" imediato sobre a pobreza.The aim of this work is to analyze the effects of cash transfers of public programs on household’s expenditures and their components, taking the Brazilian program Bolsa-Escola as a representative example.

    Diabetes mellitus (DM) is a complex disease with varying degrees of systemic and oral complications. The periodontium is also a target for diabetic damage. Diabetes is a pandemic in both developed and developing countries. In recent years, a link between periodontitis and diabetes mellitus has been postulated. The oral cavity serves as a continuous source of infectious agents that could further worsen the diabetic status of the patient and serve as an important risk factor deterioration of diabetes mellitus. The present review highlights the relationship between diabetes mellitus and periodontitis. The potential mechanisms involved in the deterioration of diabetic status and periodontal disease are also discussed. © 2011 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd.

    Full Text Available Both type 1 and type 2 diabetes have been associated with increased severity of periodontal disease for many years. More recently, the impact of periodontal disease on glycaemic control has been investigated. The role of the oral microbiota in this two-way relationship is at this stage unknown. Further studies, of a longitudinal nature and investigating a wider array of bacterial species, are required in order to conclusively determine if there is a difference in the oral microbiota of diabetics and non-diabetics and whether this difference accounts, on the one hand, for the increased severity of periodontal disease and on the other for the poorer glycaemic control seen in diabetics.

    Periodontal examination involves evaluation of soft and hard tissue parameters to gauge gingival inflammatory changes and quantify attachment loss. Conventional radiographs are vital components of this process and can be used to assess the presence of calculus and other local factors to establish a diagnosis, prognosis, and periodontal treatment plan. The 2-dimensional nature of these images limits their utility. The advent of high-resolution cone beam computed tomography (CBCT) offers 3-dimensional images that might overcome these limitations. We discuss the use of conventional radiographic techniques as well as CBCT for evaluating, diagnosing, and treatment planning patients presenting for periodontal and/or implant therapy.

A questionnaire was distributed to the participants to assess and evaluate the use of oral hygiene aids. The data were analyzed using SPSS version 17, and various comparisons were performed using the chi-square test. The study revealed that there was a statistically significant association in CPITN scores between the orthodontic and non-orthodontic patients (p < 0.01. The study showed that patients undergoing orthodontic treatment have increased plaque accumulation and probing depth resulting in periodontal tissue destruction. Proper oral hygiene practices and interdental aids should be employed to control plaque.

    Tobacco smoking is the main risk factor associated with chronic destructive periodontal disease. No other known factor can match the strength of smoking in causing harm to the periodontium. The harmful effects manifest themselves by interfering with vascular and immunologic reactions, as well as by undermining the supportive functions of the periodontal tissues. The typical characteristic of smoking-associated periodontal disease is the destruction of the supporting tissues of the teeth, with the ensuing clinical symptoms of bone loss, attachment loss, pocket formation, and eventually tooth loss. A review of the international literature that has accumulated over the past 20 years offers convincing evidence that smokers exhibit greater bone loss and attachment loss, as well as more pronounced frequencies of periodontal pockets, than non-smokers do. In addition, tooth loss is more extensive in smokers. Smoking, thus, considerably increases the risk for destructive periodontal disease. Depending on the definition of disease and the exposure to smoking, the risk is 5- to 20-fold elevated for a smoker compared to a never-smoker. For a smoker exposed to heavy long-life smoking, the risk of attracting destructive periodontal disease is equivalent to that of attracting lung cancer. The outcome of periodontal treatment is less favorable or even unfavorable in smokers. Although long-term studies are rare, available studies unanimously agree that treatment failures and relapse of disease are predominantly seen in smokers. This contention is valid irrespective of treatment modality, suggesting that smoking will interfere with an expected normal outcome following commonplace periodontal therapies. The majority of available studies agree that the subgingival microflora of smokers and non-smokers are no different given other conditions. As a consequence, the elevated morbidity in smokers does not depend on particular microflora. The mechanisms behind the destructive effects of

    Aggressive periodontitis previously termed as juvenile periodontitis is characterised by rapid destruction of the periodontium at a relatively young age. Rehabilitation of these patients is often challenging and difficult. Controlling the disease and restoring periodontal health is essential for successful prosthodontic rehabilitation. This clinical report describes an interdisciplinary approach in the rehabilitation of a young adult patient with generalised aggressive periodontitis. Treatment objectives included plaque control, prevention of further attachment loss, reduction/elimination of pockets, and prosthetic rehabilitation to enhance aesthetics and restore masticatory function. One year recall evaluation revealed stable periodontal support with no further loss of attachment and no other complications. 2015 BMJ Publishing Group Ltd.

    Prosthodontics and periodontics are collaborative disciplines. A successful prosthesis depends on a healthy periodontal environment, and periodontal health depends on the continued integrity of the prosthodontic restoration. To facilitate this collaboration, prosthodontists should not only appreciate the periodontic implications of gingival displacement procedures and tooth preparation, but should be knowledgeable about the types of gingival tissues, osseous topography, occlusal effects, and their implications for abutment choice. Working as a team, the periodontist can identify for the prosthodontist a patient's periodontal strengths and limitations. In that way, the prosthodontist can then assume responsibility for a given treatment plan based on a mutual understanding of the critical factors involved.

    The aim of this paper is to propose a single stage global treatment of endodontic, periapical and periodontal lesions in a lateral maxillary incisor with dens invaginatus. A 24 year-old woman presenting a lateral maxillary incisor with dens invaginatus in association with periapica1 and periodontal lesions underwent simultaneous surgical, endodontic and periodontal regenerative procedures. At 2, 6, 12, 18 months follow-up the radiographic healing appeared to be improved and the periapical lesion healed completely 1 year after surgical intervention. Surgery in association with endodontic and periodontal procedures represents the treatment of choice to maximize long term prognosis in cases of dens invaginatus with chronic periapical and periodontal lesions.

    Full Text Available Periodontal diseases usually refer to common inflammatory disorders known as gingivitis and periodontitis, which are caused by a pathogenic microbiota in the subgingival biofilm, including Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia and Treponema denticola that trigger innate, inflammatory, and adaptive immune responses. These processes result in the destruction of the tissues surrounding and supporting the teeth, and eventually in tissue, bone and finally, tooth loss. The innate immune response constitutes a homeostatic system, which is the first line of defense, and is able to recognize invading microorganisms as non-self, triggering immune responses to eliminate them. In addition to the innate immunity, adaptive immunity cells and characteristic cytokines have been described as important players in the periodontal disease pathogenesis scenario, with a special attention to CD4+ T-cells (T-helper cells. Interestingly, the T cell-mediated adaptive immunity development is highly dependent on innate immunity-associated antigen presenting cells, which after antigen capture undergo into a maturation process and migrate towards the lymph nodes, where they produce distinct patterns of cytokines that will contribute to the subsequent polarization and activation of specific T CD4+ lymphocytes. Skeletal homeostasis depends on a dynamic balance between the activities of the bone-forming osteoblasts (OBLs and bone-resorbing osteoclasts (OCLs. This balance is tightly controlled by various regulatory systems, such as the endocrine system, and is influenced by the immune system, an osteoimmunological regulation depending on lymphocyte- and macrophage-derived cytokines. All these cytokines and inflammatory mediators are capable of acting alone or in concert, to stimulate periodontal breakdown and collagen destruction via tissue-derived matrix metalloproteinases, a characterization of the progression of periodontitis as

    Epidemiologic studies of aggressive periodontitis have used different study designs and a range of examination methods and case definitions, and this greatly complicates the study of disease prevalence in populations. The wide range of disease case definitions, in particular, profoundly impacts the reported rate of disease, and the use of a standard disease definition is strongly recommended. Surveys of aggressive periodontitis that use only clinical examinations, without radiographic examination to confirm the presence of a distinctive pattern of tissue loss, may overestimate the prevalence of this disease, particularly when a low threshold of attachment loss is used. The prevalence of aggressive periodontitis varies significantly between populations, and differences in race/ethnicities seem to be a key factor. Studies consistently show that aggressive periodontitis is most prevalent in Africa and in populations of African descent and is least prevalent in Caucasians in Europe and North America. Among children and young adults the prevalence of this disease is higher in older than in younger age groups. Most studies show comparable disease prevalence in male and female subjects. These findings show that aggressive periodontitis is a significant health problem in certain populations. This review also highlights a lack of information on the epidemiology and demographics of this disease in many parts of the world, particularly in Asia and Africa. Epidemiologic studies of aggressive periodontitis in high-risk populations are important and could provide vital data on the determinants of this disease, and this information is needed for the establishment of effective health-promotion measures. © 2014 John Wiley & Sons A/S.

    Full Text Available Inflammatory processes in the tissues surrounding tooth root are frequent enough and develop as the direct complication of caries. As acute periodontitis is manifested with grinding toothache and violation of ph¬y¬sio¬logical act of chewing, symptoms of general intoxication, the continuous sluggish chronic periodontitis is harmful and dangerous to the organism as well. It forms the state of chronic оdontogenetic intoxication and chroneosepsis with wrong functioning of some internal organs and body systems. The like complications can cause significant disturbance to the function of kidneys, liver, heart, joints and their treatment without ablating focus of inflammation is often in- effective; this must be taken into account by doctors-interns. However, scanning of the oral cavity by conservative means has its difficulties mostly because of ignoring pathogenesis of such inflammation. That is why activity of ferments of blood dehydrogenases from the periapical tissues of the teeth affected with the chronic periodontitis was studied. The level of succinate dehydrogenase and alpha-glycerophosphate degydrogenase of lymphocytes of 110 schoolchildren aged 13-17 years old was studied. The main group of examined individuals included those of infected with tuber¬culousis – 50 individuals, and the control group (60 individuals – clinically healthy ones without tuberculousis desease. All schoolchildren had 1 or 2 teeth affected with chronic periodontitis of the apical localization. The researchers found that a significant inhibition of activity of succinate dehydrogenase and alpha-glycerophosphate degydrogenase ferments occurs in the inflammatory periodontal tissues, which indicates to local immunity decline, and as a consequence, pathogenic bacteria activation. In people infected with tuberculousis these violations were more developed. Such features of periodontitis pathogenesis must be taken into account when providing a combined treatment.

    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

    Many studies have attempted to define the relationship between postmenopausal osteoporosis and periodontal disease. Most studies support a positive association between these common diseases; however, many are cross-sectional in nature, include relatively small sample sizes, and have inadequate control of potential confounding factors, such as age, gender, hormone intake, race, and smoking, limiting our understanding of the nature of the relationship between these diseases. Clinical conditions causing low estrogen environments in postmenopausal women allow increased local production of the bone-active cytokine and the progression of periodontal disease. Prospective studies are needed to confirm or refute a causal relation.
