Full Text Available Introducción: La premedicación anestésica está destinada a reducir la ansiedad y la respuesta al estrés que supone el período anterior a la intervención quirúrgica. El temor a lo desconocido, al dolor y la separación de los padres son elementos que se añaden a la ansiedad perioperatoria en la población pediátrica. La necesidad de encontrar una vía de administración idónea en niños que no añada más sufrimientos a los ya existentes, es un reto para los anestesiólogos. Objetivo: Los objetivos del presente estudio eran valorar la eficacia, el grado de sedación y el modo de aceptación de 2 modalidades de premedicación para niños: citrato de fentanilo oral transmucoso (CFOT y midazolam oral disuelto en zumo de fruta. Material y método: Se estudiaron 2 grupos aleatorizados de 40 niños que iban a someterse a cirugía de diversas especialidades. Las dosis administradas fueron de 10 μg/kg de CFOT y 0,3 mg/kg de midazolam, administrados 30 minutos antes de la punciσn venosa.

Full Text Available Objetivos: El objetivo de este estudio ha sido conocer si el uso crónico de citrato de fentanilo oral puede guardar relación con la aparición de caries y con la pérdida de piezas dentales, y de ser así, si hubiera forma de evitar o minimizar este efecto, a propósito de la aparición de un caso en nuestra unidad. Pacientes y métodos: Se estudió el caso de un varón de 53 años en tratamiento por nuestra Clínica del Dolor, que tomaba citrato de fentanilo oral para el tratamiento de un dolor crónico en el contexto de un síndrome postlaminectomía cervical y lumbar, y en el que aparecieron varias caries y pérdida de piezas dentales. Se revisaron los 77 pacientes a los que en la actualidad, también tratábamos de forma crónica con este fármaco, para estudiar la frecuencia y magnitud de esta posible asociación. Resultados: La higiene dental de los distintos pacientes no varió durante el tratamiento con citrato de fentanilo oral. La existencia de trastornos odontógenos añadidos con posterioridad al inicio del tratamiento, no apareció en ningún otro caso. Este único paciente presentaba un aseo dental defectuoso. Conclusión: El uso crónico de citrato de fentanilo oral es un factor que puede contribuir, aunque de forma infrecuente, a la aparición de caries y pérdida de piezas dentarias. Una adecuada higiene dental podría evitar, o al menos minimizar, la repercusión del uso crónico de citrato de fentanilo oral sobre la salud dentaria.Objectives: The aim of this study was to determine whether the use of oral fentanyl citrate can be related to teeth decay and loss, and if so, whether such effect can be prevented or minimized.

Full Text Available La cirugía en la población infantil representa una fuente de disconfort para el paciente y su entorno familiar que a menudo es infravalorado tanto por éstos como por los profesionales. Aún hay mucho por hacer para disminuir este impacto y proporcionar a los niños unas condiciones emocionales adecuadas para enfrentarse a la cirugía y al postoperatorio. El objetivo de este trabajo era demostrar la utilidad del citrato de fentanilo oral transmucosa (CFOT como medio de ansiolisis preoperatorio y analgesia postoperatoria. Para ello se administró previo a la intervención 10 ug/Kg de CFOT a un grupo de 45 niños sometidos a adenoamigdalectomía y se valoró el comportamiento, la colaboración y la analgesia obtenida en el antequirófano y postoperatorio inmediato. Los resultados obtenidos se compararon con los de un grupo control similar utilizando para ello la T de student y ANOVA, obteniéndose diferencias significativas en cuanto al grado de colaboración, ansiolisis y analgesia a favor del grupo CFOT. Nosotros sostenemos que este método es además seguro, sencillo y goza de una gran aceptación por parte de los padres y profesionales implicados en el proceso asistencial.The surgery in the paedriatic population represents a source of disconfort for the patient and his familiar surroundings that often are infravalued, so much by these as by the professionals.

Métodos: Estudio abierto, prospectivo y controlado. Los pacientes fueron tratados, inicialmente, con fentanilo TTS matricial de 12 µg/h + citrato de fentanilo oral transmucosa (CFOT de 200-400 pg., para el dolor irruptivo. A los 12 días de tratamiento, se aumento la dosificación del parche matricial de fentanilo TTS, a 25 ug/h. Se valoró la situación de los pacientes mensualmente y si el dolor no estaba controlado, se aumento la dosificación de fentanilo TTS matricial. Si por el contrario, el dolor permanecía controlado durante más de un mes y no se precisaba ningún comprimido de CFOT, se redujo la dosificación del fentanilo TTS matricial. Se analizaron los registros de intensidad del dolor, calidad del descanso nocturno, efectos secundarios y consumo medio de fetanilo TTS y CFOT, obtenidos al inicio, 1º, 3º y 6º mes de tratamiento. Resultados: La EVA medio pasó del 8,86 + 0,25, inicial hasta un 2,1 + 0,74, al 6º mes. El descanso nocturno, mejoró en una proporción idéntica a la del alivio del dolor. Solo 17 pacientes (6,80% abandonaron el tratamiento por efectos secundarios 11 por náuseas-vómitos, 5 por sedación excesiva y 1 por dermatitis.

Utilización del citrato de fentanilo oral transmucosa como rescate terapéutico en pacientes con altas dosis de opioides Use of oral transmucosal fentanyl citrate for therapeutic rescue in patients receiving high doses of opiates
crisis de DI en pacientes oncológicos que tienen controlado su dolor basal con dosis altas de opioides. Las dosis de CFOT pueden considerarase como bajas en relación a las utilizadas para su dolor basal. Su administración y titulación es sencilla, aunque el paciente requiere de una educación previa a su uso.The management of breakthrough pain in cancer patients treated with high doses of opiates raises particular problems, such as the election of the drug to be used, the appropriate dosage and the route of administration. No clear guidelines on this issue are found in the medical literature, so each service decides its own particular way of acting. In this paper we review the cases dealt with over a one-year period in terms of the use of high doses of opiates in cancer patients taken care of in 2003 and treated with opiates. Objectives: -To study the group of patients treated with high doses of opiates. -To use OTFC as rescue drug for breakthrough pain events. -To analyze side and toxic effects. -To determine the preferences of the patients. Material and methods: A population of 280 patients with advanced cancer, 25 of which were receiving high doses of opiates. In these patients, breakthrough pain crises were managed with OTFC, starting with 400 micrograms. The satisfaction questionnaire proposed by Kornick was used. Results: -Easy adherence to treatment. -Average effective dose of OTFC: 600 micrograms, median of 627. -Dose titration on the second day. -Seventeen patients preferred OTFC, 6 preferred oral morphine and 2 were indifferent. Conclusions: Easy use of OTFC for the management of breakthrough pain, requiring low doses compared to the total daily dose of the patient. Patient education is required before its administration.

Full Text Available El citrato es un potente inhibidor de la cristalización de sales de calcio. La hipocitraturia es una alteración bioquímica frecuente en la formación de cálculos de calcio en adultos y especialmente en niños. El pH ácido (sistémico, tubular e intracelular es el principal determinante de la excreción de citrato en la orina. Si bien la mayoría de los pacientes con litiasis renal presentan hipocitraturia idiopática, hay un número de causas para esta anormalidad que incluyen acidosis tubular renal distal, hipokalemia, dietas ricas en proteínas de origen animal y/o dietas bajas en álcalis y ciertas drogas, como la acetazolamida, topiramato, IECA y tiazidas. Las modificaciones dietéticas que benefician a estos pacientes incluyen: alta ingesta de líquidos y frutas, especialmente cítricos, restricción de sodio y proteínas, con consumo normal de calcio. El tratamiento con citrato de potasio es efectivo en pacientes con hipocitraturia primaria o secundaria y en aquellos desordenes en la acidificación, que provocan un pH urinario persistentemente ácido. Los efectos adversos son bajos y están referidos al tracto gastrointestinal. Si bien hay diferentes preparaciones de citrato (citrato de potasio, citrato de sodio, citrato de potasio-magnesio en nuestro país solo está disponible el citrato de potasio en polvo que es muy útil para corregir la hipocitraturia y el pH urinario bajo, y reducir marcadamente la recurrencia de la litiasis renal.

Full Text Available Breakthrough cancer pain is a component of chronic cancer pain that is particularly difficult to treat due to its severity and rapid onset. Effective relief of cancer pain is an integral part of comprehensive cancer care. Many cancer patients experience persistent pain that is treated with a fixed scheduled opioid regimen. But these patients can experience acute breakthrough pain, with sudden onset that occurs spontaneously or as a result of activity. To supply this occurrence is indicated an addictional prescription of opioids. The ideal preparation for managing breakthrough pain is one that is able to mirror its characteristics, i.e. rapid in onset and relatively short in duration. Oral transmucosal fentanyl (Actiq®, an innovative form of fentanyl citrate, provides a rapid onset of pain relief and it is more appropriate than morphine for treating episodes of breakthrough pain. Besides the impact on the patients’ quality of life, cancer pain involves remarkable expenditures, as direct and indirect costs, by the National Health Care System and the Society. This study presents the estimation of the costs associated with the use of oral transmucosal fentanyl (Actiq®. Aim of the study is to verify if the use of oral transmucosal fentanyl (Actiq® can be considered as cost saving or cost effective compared with current therapy.

Full Text Available El control del dolor en el paciente oncológico es un aspecto importante en la calidad de la asistencia a las personas. El fármaco de elección en el tratamiento del DIO requiere una potencia adecuada y una muy rápida velocidad de absorción. Esta velocidad es un aspecto crítico. Las preparaciones de fentanilo, debido a su gran potencia, son probablemente los fármacos que el clínico debe emplear en el DIO, pero no todas las preparaciones de fentanilo presentan una cinética similar. Las propiedades farmacocinéticas del comprimido bucal de fentanilo (CBF con tecnología OraVescent®, han mostrado una gran velocidad de absorción, mucho más rápida que otras preparaciones de opiáceos. Se dispone de evidencia suficiente que indica que la preparación de CBF es eficaz en los episodios de DIO. El CBF ha mostrado eficacia también en dolor irruptivo no relacionado con el cáncer.

Full Text Available El dolor irruptivo (DIO consiste en una exacerbación transitoria sobre un dolor de base persistente, por lo demás controlado. Se trata de un dolor moderado o intenso, que alcanza el pico de intensidad rápidamente y tiene una duración relativamente corta. Estas características hacen del fentanilo una buena opción de tratamiento por su alta lipofilia y capacidad de absorción rápida. Aquí cobra especial importancia la vía intranasal que, por su alta vascularización y permeabilidad, constituye una ruta especialmente rápida. Recientemente se ha desarrollado un espray nasal de fentanilo mezclado con una solución de pectina denominado PecFent®. El objetivo de este estudio es realizar una revisión de los estudios publicados sobre su uso para el tratamiento del DIO. Ensayos aleatorizados, controlados, a doble ciego han demostrado un inicio del alivio del dolor en tan sólo 5 minutos tras su administración, así como el alivio del dolor clínicamente significativo en 10 min. A pesar de ser el sulfato morfina de liberación inmediata el tratamiento estándar actual de los episodios de DIO, estudios comparativos han demostrado la superioridad del fentanilo intranasal para tratar este tipo de episodios porque logra un alivio del dolor clínicamente significativo y más rápido que otros fármacos. La administración por vía nasal del fentanilo ha demostrado ser bien tolerada. En el programa de ensayos clínicos se ha objetivado la presencia de efectos adversos típicos de los medicamentos opioides en esta población. Los más frecuentes fueron vómitos, náuseas, progresión de la enfermedad y estreñimiento, siendo la mayoría de leves a moderados en intensidad. La vía nasal no presentó daños por el uso continuado de fentanilo intranasal.

An aqueous precursor solution, containing citrato-VO2+ complexes, is synthesized for the formation of monoclinic VO2. With regard to the decomposition of the VO2+ complexes towards vanadium oxide formation, it is important to gain insights into the chemical structure and transformations of the precursor during synthesis and thermal treatment. Hence, the conversion of the cyclic [V4O12](4-) ion to the VO2+ ion in aqueous solution, using oxalic acid as an acidifier and a reducing agent, is stud...

Introducción: la literatura científica indica que dos de cada tres pacientes con dolor crónico sufren con cierta frecuencia exacerbaciones puntuales del mismo debido a diferentes causas, en ocasiones previsibles, y en otras inesperadas. Además del sufrimiento que conllevan, estos episodios constituyen un problema importante para el paciente pues generan ansiedad y añaden incapacidad funcional, lo cual se traduce en una mayor dificultad para controlar el dolor basal y una menor calidad de vida...
Full Text Available Introducción: el uso de medicamentos genéricos es una práctica cada vez más frecuente, encaminada fundamentalmente al control del gasto sanitario. Los genéricos, al ser bioequivalentes con la marca original, en general son intercambiables. No obstante, hay excepciones con los medicamentos de margen terapéutico estrecho. En el caso de los opiáceos potentes, y concretamente del fentanilo transdérmico, se cuestiona la intercambiabilidad de la prescripción inicial por parte de otros médicos o farmacéuticos, ya que podría incidir en un cambio en la analgesia o en la aparición de efectos secundarios y modificar la seguridad del fármaco para un determinado paciente. Material y métodos: se han revisado las comunicaciones recibidas en nuestra unidad del dolor de pacientes previamente controlados con una marca específica de fentanilo (en todos los casos Durogesic® que fueron cambiados a otra presentación de fentanilo transdérmico por un médico distinto al prescriptor inicial o en la propia oficina de farmacia. Resultados: en un período de 2 meses se recibieron 20 comunicaciones de pérdida o disminución de la analgesia o de la presencia de efectos secundarios, previamente inexistentes bajo el tratamiento con Durogesic®, tras el cambio por una especialidad genérica de fentanilo transdérmico Conclusión: sin entrar a discutir la política del uso de genéricos, consideramos que dada la potencia de fentanilo y los posibles cambios en la concentración plasmática al intercambiar una presentación por otra, la intercambiabilidad sólo debería realizarse bajo el control del médico que inició el tratamiento o por el médico responsable del paciente, al objeto de mantener la analgesia conseguida y evitar la aparición de efectos adversos.Introduction: the use of generic drugs is becoming increasingly widespread, a practice mainly aimed at controlling health expenditure. Because generic drugs are bioequivalent with the original make

Full Text Available El fentanilo es un opioide sintético 100 veces más potente que la morfina. Sus características farmacológicas lo hacen un buen fármaco para la administración transdérmica en pacientes con dolor crónico severo de origen oncológico y no oncológico. Hasta el nuestro sólo ha sido publicado un caso referente al empleo de fentanilo transdérmico (FT en mujeres gestantes y el consiguiente síndrome de abstinencia neonatal a opiáceos (SANO. Mujer de 35 años, gestante de 23 semanas, controlada domiciliariamente por presentar dolor severo (EVA 10 en región lumbar irradiado a miembros inferiores, secundario a paraplejia tras intervención por escoliosis a los 16 años y a reintervención con artrodesis estabilizadora a los 32, y reagudizado desde la 20ª semana de gestación. Tras tratamiento inefectivo con paracetamol, metamizol, ketorolaco, petidina y cloruro mórfico, se controló el cuadro con FT a dosis de 50 mg/h y sulfato de morfina oral a dosis de 5-10 mg a demanda como rescate, que se mantuvieron durante el resto de la gestación. El parto se produjo prematuramente a las 34 semanas, y la recién nacida mostró clínica compatible con SANO en las primeras 24 horas. Fue ingresada en la UCI neonatal con intubación hasta el sexto día, siendo tratada con dosis decrecientes de cloruro mórfico hasta la suspensión previa al alta al 18º día de vida. Durante sus primeros seis meses de vida la niña ha presentado un adecuado desarrollo psicomotor. En su madre se ha reducido progresivamente la dosis de opiáceos hasta suspenderlos, sin reaparición de la clínica de dolor. El SANO aparece en recién nacidos cuyas madres han recibido opioides de forma prolongada durante la gestación. Se presenta en las primeras 24-48 horas de vida con clínica neurológica (temblor, irritabilidad, hipertonicidad, convulsiones, descoordinación, autónoma (fiebre, sudoración, digestiva (diarrea, vómitos y respiratoria (hipoventilación, taquipnea, con
Full Text Available Polímeros sintéticos biorreabsorvíveis podem ser utilizados sob a forma de membranas para sustentar e guiar o crescimento celular, através do processo de reparação tecidual. Este trabalho avaliou membranas de poli(ácido lático, PLLA, com adição de 10% de trietil-citrato usadas como curativos de feridas cutâneas agudas em ratos Wistar. Inicialmente uma ferida de 2cm² foi provocada na região dorsal de 24 animais. Estes foram divididos em 2 grupos: tratamento, nos quais as feridas foram recobertas pela membrana polimérica e controle, com feridas permanecendo cruentas. Os resultados obtidos em 1, 3, 7 e 15 dias mostraram uma resposta inflamatória mais satisfatória nas feridas protegidas pelas membranas, com reparação precoce e colágeno mais organizado quando comparadas com as áreas incialmente mantidas sem proteção. Além do que, as áreas protegidas pelas membranas não mostraram alterações inflamatórias irritativas que pudessem ser imputadas ao uso da membrana polimérica. Diante disso, conclui-se que a membrana de PLLA/Trietil-citrato protegeu efetivamente as feridas, permitindo o processo de reparação e mostrando-se promissora como curativo cutâneo.

Full Text Available OBJETIVO: Um amplo corpo de evidência oriundo de estudos experimentais indica que a sepse se associa com um aumento da produção de espécies de oxigênio reativo, depleção de antioxidantes, e acúmulo de marcadores de estresse oxidativo. Além disto, a disfunção mitocondrial foi implicada na patogênese da síndrome de disfunção de múltiplos órgãos. A citrato sintase é uma enzima que se localiza no interior das células, na matriz mitocondrial, sendo uma etapa importante do ciclo de Krebs; esta enzima foi utilizada como um marcador enzimático quantitativo da presença de mitocôndrias intactas. Assim, investigamos a atividade da citrato sintase no cérebro de ratos submetidos ao modelo sepse com de ligadura e punção do ceco. MÉTODOS: Em diferentes horários (3, 6, 12, 24 e 48 horas após cirurgia de ligadura e punção do ceco, seis ratos foram sacrificados por decapitação, sendo seus cérebros removidos e dissecados o hipocampo, estriato, cerebelo, córtex cerebral e córtex pré-frontal, e utilizados para determinação da atividade de citrato sintase. RESULTADOS: Verificamos que a atividade de citrato sintase no córtex pré-frontal estava inibida após 12, 24 e 48 horas da ligadura e punção do ceco. No córtex cerebral, esta atividade estava inibida após 3, 12, 24 e 48 horas da ligadura e punção do ceco. Por outro lado a citrato sintase não foi afetada no hipocampo, estriato e cerebelo até 48 horas após a ligadura e punção do ceco. CONCLUSÃO: Considerando-se que é bem descrito o comprometimento da energia decorrente da disfunção mitocondrial na sepse, e que o estresse oxidativo desempenha um papel essencial no desenvolvimento da sepse, acreditamos que o comprometimento da energia pode também estar evolvido nestes processos. Se a inibição da citrato sintase também ocorre em um modelo de sepse, é tentador especular que a redução do metabolismo cerebral pode provavelmente estar relacionada com a

Full Text Available Los agonistas 5-HT1A presentan efecto analgésico. El efecto analgésico de los agonistas µ puede ser bloqueado por antagonistas selectivos 5-HT1A. Para determinar el mecanismo de producción del sinergismo observado entre los receptores µ y serotoninérgico 5-HT1A en relación con su efecto antinociceptivo, determinamos el efecto analgésico de fentanilo tras estímulo nociceptivo de tipo térmico y mecánico en la rata relacionándolo con la afinidad y la densidad máxima de los receptores 5-HT1A de trece áreas cerebrales mediante técnicas de autorradiografía. Fentanilo presentó un efecto analgésico dosis y tiempo dependiente ante los dos estímulos nociceptivos. Paralelamente a la aparición del efecto analgésico, fentanilo originó una regulación a la alta de los receptores 5-HT1A al incrementar de forma dosis-dependiente su densidad sin modificar su afinidad. La dosis mayor de fentanilo (12,8 µg.kg-1 originó un incremento de la densidad de los receptores 5-HT1A estadísticamente significativo y que se correlacionó de forma positiva con su efecto analgésico en las áreas terminales corticales fronto-parietal externa (+64%, interna (+69% y piriforme (+113%, las regiones del hipocampo CA1 (+111% y DGm (+60%, los núcleos amigdalinos PMCo (+101% y AHiAL (+91% y el hipotálamo (+127%. El efecto analgésico de fentanilo en tratamiento agudo se explicaría, al menos, por dos mecanismos. Su capacidad de estimular la neurotransmisión opiácea actuando directamente sobre los receptores opiáceos µ. Y porque, al incrementar los niveles de 5-HT a nivel central y al regular a la alta los receptores 5-HT1A de zonas cerebrales terminales, se facilitaría la estimulación de estos receptores. Dado que los receptores 5-HT1A postsinápticos actúan como heteroreceptores de efecto inhibidor sobre neuronas no serotoninérgicas originando una hiperpolarización neuronal, fentanilo, al facilitar el estímulo de estos receptores originaría una

Full Text Available La cateterización de una vena central como acceso vascular para la hemodiálisis supone una alternativa rápida y segura, que permite ser utilizada inmediatamente y obtener flujos sanguíneos óptimos. Sin embargo, el uso de catéteres no está exento de complicaciones, lo que provoca una alta morbilidad aumentando las cargas de trabajo y el gasto económico. La colonización y la formación de una película producida por las bacterias (biofilm son considerados factores de riesgo, tanto en las infecciones relacionadas con catéter como en trombosis intraluminal. Para reducir estas complicaciones, utilizábamos como profilaxis un protocolo de sellado en los catéteres con una solución de heparina al 5% más gentamicina. Sin embargo, debido a complicaciones hemorrágicas, infecciosas y a una exposición constante del paciente a antibióticos, se decidió cambiar de protocolo a una solución de citrato trisódico concentrado (46,7% por sus propiedades anticoagulantes y antimicrobianas. Nuestro objetivo es valorar la implantación de un protocolo con citrato trisódico concentrado para el sellado de los catéteres. Los resultados obtenidos en este estudio son: importante descenso en el número de infecciones; menor número de manipulaciones; menor utilización de antibióticos, evitando crear resistencias y sensibilizaciones; dosis dialítica adecuada, disminución del coste económico de las cargas de trabajo y de la morbilidad de los pacientes.Placing a catheter in a central vein as vascular access for haemodialysis is a quick and safe alternative that can be used immediately and lets optimal blood flows be obtained. However, the use of catheters is not free from complications, causing high morbility and increasing the work load and economic cost. The colonization and formation of a film produced by bacteria (biofilm are considered risk factors, both in infections related to the catheter and in intraluminal thrombosis. To reduce these
Full Text Available Histoplasmosis is a systemic fungal disease that takes various clinical forms, among which oral lesions are rare. The disseminated form of the disease that usually occurs in association with Human Immunodeficiency Virus (HIV is one of the AIDS-defining diseases. Isolated oral histoplasmosis, without systemic involvement, with underlying immunosuppression due to AIDS is very rare. We report one such case of isolated oral histoplasmosis in a HIV-infected patient.

Full Text Available O óxido nítrico atua como neurotransmissor não adrenérgico e não colinérgico na bexiga e na uretra. Sua forma de ação se faz pela ativação da guanilatociclase responsável pela transformação de GMP em GMPc que promove o relaxamento da fibra muscular lisa. O citrato de sildenafil causa aumento do GMPc, através da inibição de fosfodiesterases, que hidrolisam o GMPc. Assim, o objetivo do experimento foi verificar sua ação na uretra. MÉTODOS: Estudou-se 6 ratas com peso aproximado de 200g. A anestesia foi com uretana na dose de 1,25 mg/kg. As cistometrias, em número de 3, foram realizadas através de cistostomia com cateter P50.

Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options. PMID:27343964
Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. PMID:21325845

Full Text Available Vascular anomalies comprise a widely heterogeneous group of tumours and malformations. Haemangioma is the most common benign tumour of vascular origin of the head and neck region. The possible sites of occurrence in oral cavity are lips, tongue, buccal mucosa, and palate. Despite its benign origin and behaviour, it is always of clinical importance to the dental profession and requires appropriate management. This case study reports a rare case of capillary haemangioma on the palatal gingiva in a 14-year-old female.

There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

Radiation-induced oral mucositis affects the quality of life of the patients and the family concerned. The present day management of oral mucositis is mostly palliative and or supportive care. The newer guidelines are suggesting Palifermin, which is the first active mucositis drug as well as Amifostine, for radiation protection and cryotherapy. The current management should focus more on palliative measures, such as pain management, nutritional support, and maintenance, of good oral hygiene
Although it had been shown as early as 1968 that oral rehydration therapy was as effective as intravenous rehydration therapy in the treatment of dehydration due to diarrhoea, use of oral rehydration therapy was limited to rural health centres. In large urban hospitals oral rehydration therapy was held to be inferior to intravenous therapy and tended to be used only when the latter was not available. The results reported in the article by Samadi et al. in 1983 were extremely important in help...
Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the...

Cancer is now the leading cause of death in Japan. A rapid increase in cancer mortality is expected as Japan is facing a super-aged society. Many causes of cancer are known to be closely linked to life style factors, such as smoking, drinking, and diet. The oral environment is known to be involved in the pathogenesis and development of various diseases such as bronchitis, pneumonia, diabetes, heart disease, and dementia. Because the oral cavity acts as the bodily entrance for air and food, it is constantly exposed to foreign substances, including bacteria and viruses. A large number of bacteria are endemic to the oral cavity, and indigenous oral flora act to prevent the settlement of foreign bacteria. The oral environment is influenced by local factors, including dental plaque, tartar, teeth alignment, occlusion, an incompatible prosthesis, and bad lifestyle habits, and systemic factors, including smoking, consumption of alcohol, irregular lifestyle and eating habits, obesity, stress, hormones, and heredity. It has recently been revealed that the oral environment is associated with cancer. In particular, commensal bacteria in the oral cavity are involved in the development of cancer. Moreover, Candida, human papilloma virus and Epstein-Barr virus as well as commensal bacteria have been reported to be associated with the pathogenesis of cancer. In this review, we introduce recent findings of the correlation between the oral environment and cancer. PMID:27482300

Pregnancy is the time when conscious approach to preventive oral care should increase. Preventive measures during pregnancy Preventive measures during pregnancy mean usage of fluorides, special dietary measures and increased oral hygiene habits. Preventive measures in pregnant women have one goal: providing conditions for development of fetal teeth as well as preventing tooth decay in pregnant women. The optimal period for introducing preventive measures is the first trimester of pregnancy. Alterations of oral health during pregnancy Because of hormonal alterations there is an increased incidence of dental diseases: gingivitis and low salivary pH (inflammation and bleeding gums. Impact of nutrition during pregnancy on oral health Eating habits of pregnant women may lead to frequent snacking on candy or other decay-promoting foods, thereby increasing the risk of caries. However, very poor oral health, possible dental complications and their consequences to the health as well as emotional status represent very strong reasons for activation of dental health care in this period.

Full Text Available Oral sex is commonly practiced by sexually active couples of various age groups, including male-female and same-gender adolescents. The various type of oral sex practices are fellatio, cunnilingus, and analingus. Oral sex can transmit oral, respiratory, and genital infections from one site in body to the other. Oral health has a direct correlation on the transmission of infection; a cut in the mouth, bleeding gums, lip sores or broken skin increases chances of life-threatening infections. Although oral sex is considered a low risk activity, it is important to use protection such as physical barriers, health and medical issues, ethical issues, and oral hygiene and dental issues. The ulcerations or unhealthy periodontium in mouth accelerates the phenomenon of transmission of infections into the circulation. Thus, consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

Oral cancer is one of the major global threats to public health. The development of oral cancer is a tobacco-related multistep and multifocal process involving field cancerization and carcinogenesis. The rationale for molecular-targeted prevention of oral cancer is promising. Biomarkers of genomic instability, including aneuploidy and allelic imbalance, are possible to measure the cancer risk of oral premalignancies. Understanding of the biology of oral carcinogenesis will yield important adv...

A growing body of evidence implicates human oral bacteria in the etiology of oral and gastrointestinal cancers. Epidemiological studies consistently report increased risks of these cancers in men and women with periodontal disease or tooth loss, conditions caused by oral bacteria. More than 700 bacterial species inhabit the oral cavity, including at least 11 bacterial phyla and 70 genera. Oral bacteria may activate alcohol and smoking-related carcinogens locally or act systemically, through c...

Oral sex is commonly practiced by sexually active couples of various age groups, including male-female and same-gender adolescents. The various type of oral sex practices are fellatio, cunnilingus, and analingus. Oral sex can transmit oral, respiratory, and genital infections from one site in body to the other. Oral health has a direct correlation on the transmission of infection; a cut in the mouth, bleeding gums, lip sores or broken skin increases chances of life-threatening infections. Alt...

While initially the oral cavity was considered to be mainly a source of various bacteria, their toxins and antigens, recent studies showed that it may also be a location of oxidative stress and periodontal inflammation. Accordingly, this paper focuses on the involvement of melatonin in oxidative stress diseases of oral cavity as well as on potential therapeutic implications of melatonin in dental disorders. Melatonin has immunomodulatory and antioxidant activities, stimulates the proliferatio...

Oral habits, if persist beyond certain developmental age, can pose great harm to the developing teeth, occlusion, and surrounding oral tissues. In the formative years, almost all children engage in some non-nutritive sucking habits. Clinicians, by proper differential diagnosis and thorough understanding of natural growth and developmental processes, should take a decision for intervening. This article describes case series reports of thumb sucking, finger sucking, and tongue thrusting habits,...

Pyogenic granuloma is one of the inflammatory hyperplasias seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection and in reality arises in response to various stimuli such as low-grade local irritation, traumatic injury, or hormonal factors. It predominantly occurs in the second decade of life in young females, possibly because of the vascular effects of female hormones. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic lesion manife...

The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

Immune mediated diseases of oral cavity are uncommon. The lesions may be self-limiting and undergo remission spontaneously. Among the immune mediated oral lesions the most important are lichen planus, pemphigus, erythema multiformi, epidermolysis bullosa, systemic lupus erythematosis. Cellular and humoral mediated immunity play a major role directed against epithelial and connective tissue in chronic and recurrent patterns. Confirmatory diagnosis can be made by biopsy, direct and indirect imm...

Full Text Available The paper analyzes a rise in the incidence of oral cancer in the Rostov Region since the 1990s. The study has indicated that this rise is associated with regional population growth due to the forced migrants after the collapse of the USSR. Financial problems, unbalanced nutrition, poor oral hygiene, and depression in this group of patients have contributed to the higher incidence of precancers and cancers.

Photoprotection can be provided not only by ultraviolet (UV) blockers but also by oral substances. Epidemiologically identified associations between foods and skin cancer and interventional experiments have discovered mechanisms of UV skin damage. These approaches have identified oral substances that are photoprotective in humans. UV inhibits adenosine triphosphate (ATP) production causing an energy crisis, which prevents optimal skin immunity and DNA repair. Enhancing ATP production with oral nicotinamide protects from UV immunosuppression, enhances DNA repair and reduces skin cancer in humans. Reactive oxygen species also contribute to photodamage. Nontoxic substances consumed in the diet, or available as oral supplements, can protect the skin by multiple potential mechanisms. These substances include polyphenols in fruit, vegetables, wine, tea and caffeine-containing foods. UV-induced prostaglandin E2 (PGE2 ) contributes to photodamage. Nonsteroidal anti-inflammatory drugs and food substances reduce production of this lipid mediator. Fish oils are photoprotective, at least partially by reducing PGE2 . Orally consumed substances, either in the diet or as supplements, can influence cutaneous responses to UV. A current research goal is to develop an oral supplement that could be used in conjunction with other sun protective strategies in order to provide improved protection from sunlight. PMID:24313740

Full Text Available INTRODUCTION: Oral Myiasis, a condition of infestation of the body by fly larvae (maggots is a rare pathology in humans. It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

Although excisional surgery is the treatment of choice , some other treatment protocols such as the use of Nd:YAG laser, flash lamp pulsed dye laser, cryosurgery, intralesional injection of ethanol or corticosteroids, and sodium tetradecyl sulfate sclerotherapy have been proposed. We present the case of a 25-year-old pregnant woman with large oral pyogenic granuloma.

Divers can have several oral problems. Firstly, problems caused by pressure changes. These are barodontalgia and odontocrexis. Barodontalgia is toothache by barotrauma. Odontocrexis is restorations coming lose or breaking or tooth fractures by expansion of air beneath restorations. Other problems can occur by cements used to fix casted restorations, by inflammations in the orofacial region, and by not yet fully healed oral wounds. Secondly, there are problems related to the diver's mouthpiece. To keep the mouthpiece in place, the mandible has to be forced in a forward position. Holding this position often and for long periods of time, may develop or aggravate temporomandibular dysfunction. Insufficient fit of the mouthpiece may induce oral mucosal lesions. Therefore, it is recommended to produce individual diver mouthpieces. It is also recommended to produce individual diver mouthpieces for complete dentures wearing divers and for divers with fixed orthodontic appliances. PMID:15932043

Full Text Available Oral myiasis is a rare condition in humans and is associated with poor oral hygiene, severe halitosis, mouth breathing during sleep, mental handicap, cerebral palsy, epilepsy, anterior open bite, incompetent lips, and other conditions. In this report, a 14 year-old boy who had an orofacial trauma in the maxillary dentoalveolar region,which was neglected, has been described. There was a deep lacerated wound on the upper vestibule which was infected and maggots were found on the same wound. The clinical features, management, treatment are discussed and relevant literature is reviewed.
Full Text Available Oral myiasis is a rare disease caused by larvae of dipteran flies. Houseflies are strongly suspected of transmitting at least 65 diseases to humans, including typhoid fever, dysentery and cholera. Flies regurgitate and excrete wherever they come to rest and thereby mechanically are the root cause for disease organisms. A case of oral myiasis caused by Chrysomya bezziana in the maxillary anterior region in a 40-year-old patient is presented. Manual removal of maggots, and surgical debridement of wound was done followed by broad-spectrum anti-parasitic medications. A note on the identification of the larva and histopathology of the tissue is also highlighted here.

Abstract. Oral allergy syndrome (OAS) is defined as a set of clinical manifestations caused by IgE-mediated allergic reactions that occur at oral and pharyngeal mucosae in the patients with pollen sensitization after ingestion of certain fruits, vegetables, nuts and spices. OAS arises from cross-reactivity between specific pollen and food allergens, due to similarity of a configuration and amino acid sequence of allergenic molecules. OAS is considered as class II food allergy, ...
Lichen planus is a mucocutaneous dermatological disorder, with intraoral manifestation. Skin lesions prevail with oral mucosal lesions. Prevalence of lichen planus, as an oral pre-malignant lesion, is 1-2 % population. Lateral border, dorsal tongue, gingiva, hard palate and vermilion border are common sites and lesions appear as reticular, plaque-like and papular intraoral types. Skin presents with pururitic, polygonal papules. Atrophic and erosive are the known intraoral pre-malignant types. A case report is presented, which responded well to steroid therapy. (author)

Oral diseases are known to be closely associated with oral biofilm metabolism, while cancer tissue is reported to possess specific metabolism such as the ‘Warburg effect’. Metabolomics might be a useful method for clarifying the whole metabolic systems that operate in oral biofilm and oral cancer, however, technical limitations have hampered such research. Fortunately, metabolomics techniques have developed rapidly in the past decade, which has helped to solve these difficulties. In vivo meta...

Full Text Available The title compound, [Zn3(C6H5O72(H2O2]n, is a polymer in which the repeating unit contains three zinc atoms, two hepta-dentate Hcit ligands (Hcit = citric acid trianion and two coordinated water molecules, only half of which are independent due to one of the metal atoms lying on a centre of symmetry. The two independent cations both exhibit an octahedral geometry, but the way in which they are coordinate are different; while the Zn atom in a general position is bound to three Hcit ligands and one water molecule, the one at the centre of symmetry is coordinated by six O atoms from two symmetry-related Hcit ligands through the (protonated hydroxyl and carboxylate groups. The three carboxylate groups coordinate to the Zn centres in three different ways, viz. chelating, bridging and a mixture of both, in an unusual coordination mode for citrate. The result is a two-dimensional structure parallel to (010, built up by a square-grid motif. Intermolecular O—H...O hydrogen bonds are present in the crystal structure

On the 50th birthday of the pill, it is appropriate to recall the milestones which have led to its development and evolution during the last five decades. The main contraceptive effect of the pill being inhibition of ovulation, it may be called a small miracle that this drug was developed long before the complex regulation of ovulation and the menstrual cycle was elucidated. Another stumbling block on its way was the hostile climate with regard to contraception that prevailed at the time. Animal experiments on the effect of sex steroids on ovulation, and the synthesis of sex steroids and orally active analogues were the necessary preliminaries. We owe the development of oral contraceptives to a handful of persons: two determined feminists, Margaret Sanger and Katherine McCormick; a biologist, Gregory Pincus; and a gynaecologist, John Rock. Soon after the introduction of the first pills, some nasty and life-threatening side effects emerged, which were due to the high doses of sex steroids. This led to the development of new preparations with reduced oestrogen content, progestins with more specific action, and alternative administration routes. Almost every decade we have witnessed a breakthrough in oral contraception. Social and moral objections to birth control have gradually disappeared and, notwithstanding some pill scares, oral contraceptives are now one of the most used methods of contraception. Finally, all's well that ends well: recent reports have substantiated the multiple noncontraceptive health benefits paving the way for a bright future for this 50-year-old product. PMID:21091163

Now in its fourth year, the AAS Oral History Project has interviewed over 80 astronomers from all over the world. Led by the AAS Historical Astronomy Division (HAD) and partially funded by the American Institute of Physics Niels Bohr Library and ongoing support from the AAS, volunteers have collected oral histories from astronomers at professional meetings starting in 2015, including AAS, DPS, and the IAU general assembly. Each interview lasts one and a half to two hours and focuses on interviewees’ personal and professional lives. Questions include those about one’s family, childhood, strong influences on one’s scientific career, career path, successes and challenges, perspectives on how astronomy is changing as a field, and advice to the next generation. Each interview is audio recorded and transcribed, the content of which is checked with each interviewee. Once complete, interview transcripts are posted online as part of a larger oral history library at https://www.aip.org/history-programs/niels-bohr-library/oral-histories. Future analysis will reveal a rich story of astronomers and will help the community address issues of diversity, controversies, and the changing landscape of science. We are still recruiting individuals to be interviewed from all stages of career from undergraduate students to retired and emeritus astronomers. Contact Jarita Holbrook to schedule an interview or to find out more information about the project (email@example.com). Also, contact Jarita Holbrook if you would like to become an interviewer for the project.

Age-related oral changes are seen in the oral hard and soft tissues as well as in bone, the temporomandibular joints and the oral mucosa. As older patients retain their natural teeth for longer, the clinical picture consists of normal physiological age changes in combination with pathological and iatrogenic effects. Clinical Relevance: With an ageing population retaining more of its natural teeth for longer, dental professionals should expect to observe oral age changes more frequently.
Aim: The main aim of this thesis was to generate initiatives promoting good oral health for institutionalised elderly. It was therefore essential to investigate how their oral health status has changed over time, whether care professionals have adequate oral care knowledge and if the oral hygiene of the institutionalised elderly can be improved in the long-term by a new quality assurance system. Methods: Several different methods were used, with both descriptive and analytical ...

Full Text Available Background: Vitiligo is one of the disorder that has social impact . Both skin and mucous membrane show depigmentation in vitiligo. Depigmentation in oral cavity can be more easily observed and the patient can be given awareness regarding the condition if they are unaware of vitiligo elsewhere in their body and can be guided for treatment. Aim and objectives: The aim of this study is to determine the frequency of occurrence of oral mucosal vitiligo in vitiligo patients and to determine the most commonly involved oral mucosal site. Materials and methods: The study sample included 100 vitiligo patients. The patients of all age groups and both genders were included. Vitiligo patients associated with systemic conditions such as thyroid disorders, juvenile diabetes mellitus, pernicious anemia, Addison′s disease were excluded in this study. Results: Out of 100 vitiligo patients 44 % male and 56% were female. The oral presentation of vitiligo in this study showed depigmentation of buccal mucosa in 5% of patients, labial mucosa in 5% of patients, palate in 8% of patients, gingiva in 2% of patients and alveolar mucosa 1% . Depigmentation of lip was seen in 42% of patients. Lip involvement refers to depigmentation of both the lips or either lip. Also vermilion border involvement was noted in majority of cases. In some cases, the depigmentation of lip extended to the facial skin also. Conclusion: In this study 55 patients out of 100 patients showed depigmentation in the oral cavity. Lip involvement was most common in this study showing about 42% of patients. Intraoral mucosal involvement was found in 21% of patients. Among intraoral mucosal site palate was common followed by buccal and labial mucosa, gingiva. Two patients had lip pigmentation as the only manifestation without any depigmentation in the skin.

Full Text Available There is a clear reported association between social disparity and oral health, for example, between dental caries and malnutrition in children. This fact is detected in several studies, and also found amongst the Brazilian population. However, several efforts have been made to improve the quality of life of the population and to achieve the 2015 Millennium Development Goals. Oral health is a branch to be improved among these goals. The Brazilian experience has been drawing the attention of authorities, insofar as there have been direct improvements in oral health through state oral health programs, and also indirect results by improving the quality of life of the population. Included within the Brazilian oral health programs are the Family Health Program and Smiling Brazil Program. The former is a global healthcare program which involves primary oral healthcare, while the latter is a specialized oral care program. Among the social programs that would indirectly improve oral health are Family Stipend and the Edmond and Lily Safra International Institute of Neuroscience of Natal (ELS-IINN. In conclusion, although oral health problems are related to socioeconomic factors, the implementation of primary oral health programs and programs to improve the population's quality of life may directly or indirectly improve the oral health scenario. This fact is being observed in Brazil, where the oral health policies have changed, and social programs have been implemented.

Full Text Available Immune mediated diseases of oral cavity are uncommon. The lesions may be self-limiting and undergo remission spontaneously. Among the immune mediated oral lesions the most important are lichen planus, pemphigus, erythema multiformi, epidermolysis bullosa, systemic lupus erythematosis. Cellular and humoral mediated immunity play a major role directed against epithelial and connective tissue in chronic and recurrent patterns. Confirmatory diagnosis can be made by biopsy, direct and indirect immunoflouresence, immune precipitation and immunoblotting. Therapeutic agents should be selected after thorough evaluation of immune status through a variety of tests and after determining any aggravating or provoking factors. Early and appropriate diagnosis is important for proper treatment planning contributing to better prognosis and better quality of life of patient.

Diagnosis of oral and facial pain is often difficult because several anatomical structures within this small area are capable of producing similar symptoms, and pain referred from cranial or distant sites and emotional or psychiatric disturbances complicate matters further. This article summarizes some of the more common causes of orofacial pain, with the exception of disorders of the temporomandibular joint and associated musculature, which are covered in a separate article.

The discovery during the first half of the 20th century of the link between natural fluoride, adjusted fluoride levels in drinking water and reduced dental caries prevalence proved to be a stimulus for worldwide on-going research into the role of fluoride in improving oral health. Epidemiological studies of fluoridation programmes have confirmed their safety and their effectiveness in controlling dental caries. Major advances in our knowledge of how fluoride impacts the caries process have led to the development, assessment of effectiveness and promotion of other fluoride vehicles including salt, milk, tablets, toothpaste, gels and varnishes. In 1993, the World Health Organization convened an Expert Committee to provide authoritative information on the role of fluorides in the promotion of oral health throughout the world (WHO TRS 846, 1994). This present publication is a revision of the original 1994 document, again using the expertise of researchers from the extensive fields of knowledge required to successfully implement complex interventions such as the use of fluorides to improve dental and oral health. Financial support for research into the development of these new fluoride strategies has come from many sources including government health departments as well as international and national grant agencies. In addition, the unique role which industry has played in the development, formulation, assessment of effectiveness and promotion of the various fluoride vehicles and strategies is noteworthy. This updated version of 'Fluoride and Oral Health' has adopted an evidence-based approach to its commentary on the different fluoride vehicles and strategies and also to its recommendations. In this regard, full account is taken of the many recent systematic reviews published in peer reviewed literature. PMID:27352462

Oral health includes freedom from disease in the gums, the mucosa and the teeth. There has been a striking reduction in dental caries and periodontitis in industrialized countries, although the proportion with severe disease has remained at 10-15%, and the prevalence increases in less developed countries. If left untreated, these diseases may lead to pain, and impaired quality of life and nutritional status. Prevention and treatment need, besides traditional implementation of proper oral hygiene, sugar restriction and use of fluoride, newer cost-effective strategies. Non-sweetened dairy products, which are proven non-cariogenic, or specific bioactive components from alike sources might prove to be part of such strategies. Thus, milk proteins, such as bovine and human caseins and lactoferrin, inhibit initial attachment of cariogenic mutans streptococci to hydroxyapatite coated with saliva or purified saliva host ligands. In contrast, both bovine and human milk coated on hydroxyapatite promotes attachment of commensal Actinomyces naeslundii and other streptococci in vitro, and phosphorylated milk-derived peptides promote maintenance of tooth minerals, as shown for the β-casein-derived caseino-phosphate peptide. Observational studies are promising, but randomized clinical trials are needed to reveal if dairy products could be a complementary treatment for oral health. PMID:21335990

Dermatologists often prescribe oral tetracycline for the control of acne, primarily, and to a much lesser extent, for the treatment of cutaneous infections. A number of the patients taking tetracycline are also taking birth control pills. A recent article in the British Medical Journal (1980;1:293) indicates that this combination can lead to a failure of the (OC) oral contraceptive. Such failure had been associated with ampicillin as well. It is believed that the mechanism for this was the disturbance in normal gut flora, with consequent effects on bacterial hydrolysis of steroid conjugates. This would interrupt the enterohepatic circulation of contraceptive steroids, resulting in a less than normal concentration of circulating steroids. It was recommended that women taking low-dose OCs take extra precautions against pregnancy during any cycle in which antibiotics are given. In regard to our care of and responsibilities to our patients, and in an era when malpractice suits for all types of reasons are more common, it certainly behooves dermatologists to recognize and be concerned about this potential consequence of prescribing oral antibiotics.

Full Text Available Introduction: Lymphangioma is a change of lymphatic vessels that frequently affects the head and neck region. Its occurrence at oral cavity is rare and it is most commonly identified at the anterior two-thirds of the tongue. At this location, it is clinically characterized as transparent and generally grouped vesicles, which can be red or purple. The deep lesions appear as nodular masses of variable color and superficial texture. It can be classified according to the size of vessels into three types: capillary, cavernous, and cystic lymphangioma. Several types of treatment have been suggested; and the most commonly used treatments are: surgical excision, application of carbon dioxide laser, cryotherapy using liquid nitrogen, and sclerosing agents. Objective and case report: To describe a case of oral lymphangioma diagnosed in a 17-year-old female patient. The lesion was presented as multiple vesicles of soft consistency with thin epithelial lining and color ranging from translucent to yellow-reddish, involving the soft palate and the left retromolar region. Incisional biopsy confirmed the hypothesis of cavernous lymphangioma. Patient was followed-up for one year without signs of lesion relapse. Conclusion: Through this clinical case report and literature review, this study emphasizes the relevance of the clinical and histopathological features that should be considered to confirm the clinical hypothesis and indicate the proper therapeutic for oral lymphangiomas.

This study, which is motivated by the substantial morbidity of local signs of mucositis and generalized symptoms that result from mucositis induced by therapeutic irradiation, has the following objectives: To investigate if it is possible to prevent irradiation mucositis via oral flora elimination, and, if it is true that flora plays a role in irradiation mucositis, what fraction of the oral flora may be involved; to evaluate oral Gram-negative bacillary carriage; to investigate the possibility to eradicate Gram-negative bacilli from the oral cavity; to evaluate oral yeast carriage; to investigate the possibility to eradicate yeasts stomatitis and the 'selectivity' of elimination of flora. Two methods are described for monitoring alterations of mucositis of the oral cavity and changes in oral flora. Chlorhexidine has been tested as the commonly used prophylaxis. The effect of chlorhexidine 0.1% rinses on oral flora and mucositis has been studied in a prospective placebo controlled double blind randomized programme. The results of the influence of saliva on the antimicrobial activity of chlorhexidine and the results of selective elimination of oral flora in irradiated patients who have head and neck cancer are reported. Salivary inactivation of the topical antimicrobials used for selective elimination of oral flora has been studied and the results are reported. Finally, the objectives that have been achieved (or not) are delineated. The significance of the results of the study are discussed in terms of published information and further lines of research are suggested. (author). 559 refs.; 29 figs.; 20 tabs

Full Text Available Thromboembolic disease (TED is the leading cause of morbidity and mortality worldwide. The hallmark of oral long-term anticoagulant therapy has been the use of vitamin K antagonists, whose anticoagulant effect is exerted inhibiting vitamin K epoxide reductase. Warfarin and acenocoumarol are the most commonly used. In the last five years several new drugs for long term anticoagulation have been developed, which can inhibit single clotting factors with the purpose of improving drug therapeutic range and, ideally, minimizing bleeding risks. This review addresses the state of the art on the clinical use of inhibitors of activated factor X and thrombin.

Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications

Full Text Available Both immunologic and nonimmunologic drug reactions can be seen in oral mucosa. Since considerable number of these reactions heals spontaneously without being noticed by the patients, exact frequency of the lesions is unknown. Most common lesions are xerostomia, taste disorders, mucosal ulcerations and edema. In this article, oral lesions resulting from drug intake similar to those from oral lesions of local and systemic diseases, and diagnostic problems caused by these similarities, have been reviewed.

Full Text Available Oral myiasis is a relatively rare pathology in humans caused by invasion of body tissue or cavities of living animals or humans by larvae of certain dipteran flies. It is an uncommon clinical condition, being more frequent in underdeveloped countries, and in countries with tropical climate. Common pre-disposing factors are poor oral hygiene, halitosis, trauma, senility, suppurative oral lesions, and in patients with neuro-psychiatric deficits. The present article reports a case of oral myiasis involving the anterior palate in a physically and mentally disabled 24-year-old female patient.
Full Text Available Although oral health is a major determinant of general health and quality of life, it has a low priority in the context of mental illness. Chronic mental illness and its treatment carry inherent risks for significant oral diseases. Both the disease itself and its various pharmacologic management modalities lead to a range of oral complications and side effects, with caries, periodontal disease and xerostomia being encountered most frequently. Older age, female gender, length of hospitalization, duration of mental illness, psychiatric diagnosis are the most discussed predictors for adverse dental outcomes in the reviewed studies. Poor oral hygiene, higher intake of carbonates, smoking, poor perception of oral health self-needs, length of psychiatric disorder, length of psychotropic treatment, and less access to dental care pose at high risk for poor oral health among this population. This article emphasizes the importance of preventive dentistry programs to improve dental healthcare psychiatric chronic inpatients and the signifance of bridging dental health education to psychiatric rehabilitation programs. In this review, general information concerning the oral manifestations of mental illness, effect of medication of mental illness on oral health, the factors affecting oral health among this special population have been provided.

Management of oral biofilms allows dentists to help control the pathogens responsible for periodontal disease and decay. Increasing evidence indicates that the oral system is a portal for pathogenic microorganisms. This is a cumulative situation with systemic effects that can overcome an individual's resistance threshold, culminating in systemic sequela. New evidence indicates that controlling these oral pathogens has systemic benefits, as oral pathology is related to cardiovascular and respiratory disease, diabetes, and systemic inflammatory responses, as well as low birth weight and pre-term deliveries. Some insurance companies now cover periodontal scaling for gingivitis and periodontal disease for pregnant women and patients at risk for pregnancy. PMID:17511362

Oral jewelry is popular. One of the most widely spread types are so-called tooth diamonds made of composite materials which are applied to the teeth with an adhesive. Note that parents are required to sign a release form for under-aged patients in Switzerland. Tooth cap grills and gold teeth are considered status symbols within the Hip-Hop fashion scene. However, tooth ornaments favour the accumulation of plaque and can diminish the ability to articulate. With respect to jewelry in oral soft tissue especially tongue and lip piercings are of significance to dentists. Besides the systemic complications, which are mostly caused by a lack of hygiene or the failure of noting medical contraindications by the piercer, local complications occur frequently. After surgery, pain, swelling, infections as well as hemorrhages or hematomas can be observed. Long-term effects can be problematic: gingival recession can be discernes mainly in the case of lip piercings the loss of hard tooth substance in the case of tongue piercings. Because of that, conservation therapies can become indespensable. Patients wearing dental jewelry have to be aware of risks of tooth damage, and they regularly have to undergo dental check-ups. Information campaigns--for dentists as well as patients--are necessary. PMID:20112640

The reactions of oral V(V/IV) anti-diabetic drugs within the gastrointestinal environment (particularly in the presence of food) are a crucial factor that affects their biological activities, but to date these have been poorly understood. In order to build up reactivity-activity relationships, the first detailed study of the reactivities of typical V-based anti-diabetics, Na3V(V)O4 (A), [V(IV)O(OH2)5](SO4) (B), [V(IV)O(ma)2] (C, ma = maltolato(-)) and (NH4)[V(V)(O)2(dipic)] (D, dipic = pyridine-2,5-dicarboxylato(2-)) with simulated gastrointestinal (GI) media in the presence or absence of food components has been performed by the use of XANES (X-ray absorption near edge structure) spectroscopy. Changes in speciation under conditions that simulate interactions in the GI tract have been discerned using correlations of XANES parameters that were based on a library of model V(V), V(IV), and V(III) complexes for preliminary assessment of the oxidation states and coordination numbers. More detailed speciation analyses were performed using multiple linear regression fits of XANES from the model complexes to XANES obtained from the reaction products from interactions with the GI media. Compounds B and D were relatively stable in the gastric environment (pH ∼ 2) in the absence of food, while C was mostly dissociated, and A was converted to [V10O28](6-). Sequential gastric and intestinal digestion in the absence of food converted A, B and D to poorly absorbed tetrahedral vanadates, while C formed five- or six-coordinate V(V) species where the maltolato ligands were likely to be partially retained. XANES obtained from gastric digestion of A-D in the presence of typical food components converged to that of a mixture of V(IV)-aqua, V(IV)-amino acid and V(III)-aqua complexes. Subsequent intestinal digestion led predominantly to V(IV) complexes that were assigned as citrato or complexes with 2-hydroxyacidato donor groups from other organic compounds, including certain

The prevalence of prosthodontic treatment has been well recognized, and the need is continuously increasing with the ageing population. While the oral mucosa plays a critical role in the treatment outcome, the associated biomechanics is not yet fully understood. Using the literature available, this paper provides a critical review on four aspects of mucosal biomechanics, including static, dynamic, volumetric and interactive responses, which are interpreted by its elasticity, viscosity/permeability, apparent Poisson's ratio and friction coefficient, respectively. Both empirical studies and numerical models are analysed and compared to gain anatomical and physiological insights. Furthermore, the clinical applications of such biomechanical knowledge on the mucosa are explored to address some critical concerns, including stimuli for tissue remodelling (interstitial hydrostatic pressure), pressure–pain thresholds, tissue displaceability and residual bone resorption. Through this review, the state of the art in mucosal biomechanics and their clinical implications are discussed for future research interests, including clinical applications, computational modelling, design optimization and prosthetic fabrication.

Full Text Available The diagnosis between different diseases may be impaired by clinical and histopathologic similarities, as observed in the oral lichen planus (OLP and oral lichenoid lesion (OLL. Inspite of similar clinicopathological features; etiology, diagnosis and prognosis differ which mandates separation of OLL from OLP. Hence, it is essential for the oral physician and oral pathologist to be familiarized with the individual variations among clinicopathological features of OLP and OLL as well as to obtain a thorough history and perform a complete mucocutaneous examination in addition to specific diagnostic testing. The difficulties faced to establish the diagnosis between these two pathologies are widely investigated in the literature with a lack of definite conclusion. This review is an attempt to throw some light on these clinicopathologic entities with the aim to resolve the diagnostic dilemma.

The oral health is influenced by systemic health, and one of the most common chronic diseases encountered in dental practice is diabetes mellitus. Diabetes can worsen oral infections and vice versa. In the literature, periodontitis and diabetes in the young to middle-aged adults have been the most widely researched area. Understanding the patho-physiology, clinical manifestations and management of different types of orofacial diseases in diabetic patients are important to the diabetologist and the dentist for the optimal care of patients with these diseases. This review explores the inter-link between diabetes and oral health. PMID:25487035

A laboratory study was undertaken with volunteer females (aged 20-25) to determine the effect of OCs (oral contraceptives) on hematologic and metabolic variables during exercise. 5 of the women studied were naturally cycling and 7 were taking OCs. The women worked at 2 workloads on a bicycle ergometer at 50% and 90% of their maximal aerobic capacity during 3 different phases of their menstrual cycle. There was no better time of the month for doing the 50% or the 90% workload in either group. Heartrate for the OC group was significantly higher at the 50% maximal capacity. Results of the test indicate tha women on OCs have somewhat reduced cardiac efficiency and are ventilating more to carry out a given amount of work when compared to women who are naturally cycling. Possible explanations for the higher heart rate are put forward. The main limitation of the study is that the subject numbers involved are small and the number of cycles studied is also small.

Full Text Available It has been shown that 40–60% of the bacteria found in different healthy and diseased oral sites still remain to be grown in vitro, phenotypically characterized, and formally named as species. The possibility exists that these as-yet-uncultivated bacteria play important ecological roles in oral bacterial communities and may participate in the pathogenesis of several oral infectious diseases. There is also a potential for these as-yet-uncultivated oral bacteria to take part in extra-oral infections. For a comprehensive characterization of physiological and pathogenic properties as well as antimicrobial susceptibility of individual bacterial species, strains need to be grown in pure culture. Advances in culturing techniques have allowed the cultivation of several oral bacterial taxa only previously known by a 16S rRNA gene sequence signature, and novel species have been proposed. There is a growing need for developing improved methods to cultivate and characterize the as-yet-uncultivated portion of the oral microbiome so as to unravel its role in health and disease.

Multiple sclerosis (MS) is a complex autoimmune disease of the central nervous system. Disease-modifying drugs licensed for MS treatment have been developed to reduce relapse rates and halt disease progression. The majority of current MS drugs involve regular, parenteral administration, affecting long-term adherence and thus reducing treatment efficacy. Over the last two decades great progress has been made towards developing new MS therapies with different modes of action and biologic effects. In particular, oral drugs have generated much interest because of their convenience and positive impact on medication adherence. Fingolimod was the first launched oral treatment for relapsing-remitting MS; recently, Teriflunomide and Dimethyl fumarate have also been approved as oral disease-modifying agents. In this review, we summarize and discuss the history, pharmacodynamics, efficacy, and safety of oral agents that have been approved or are under development for the selective treatment of MS.

The oral cavity is a rare site for extrapulmonary tuberculosis. A case is reported of a young woman with dysphagia and oral ulceration. The original mucosal biopsy was negative on smear for acid-fast bacilli, and the patient subsequently developed pulmonary symptoms. A diagnosis of Mycobacterium tuberculosis was ultimately made on open lung biopsy. Complete resolution of both mouth lesion and chest involvement occurred with standard antituberculous therapy.

Full Text Available Oral splints have been frequently used in the treatment of bruxism to protect teeth and periodontium from damage, but the mechanism of action and efficacy of oral splints remain controversial. It has been suggested that they can be used to treat bruxism, based on the assumption that the device can eliminate or remove occlusal interference. Currently there are no reliable data to support the assumption of occlusion as an etiologic factor for bruxism, because several other factors have a role in bruxism, such as psychiatric, neurological and systemic disorders. In this paper, the mechanism of action and efficacy of oral splints in bruxism are discussed. Conclusions: although oral splint may be beneficial in protecting the dentition, the efficacy of this device in reducing bruxism is still not confirmed. There are several aspects that would support the broad usage of oral splints in the treatment of bruxism, but there are also limitations associated with each of these aspects. In conclusion, oral splints can be considered as useful adjuncts in the management of sleep bruxism but not as a definitive treatment.DOI: 10.14693/jdi.v15i1.82

Full Text Available Objective: To assess the efficacy of oral health instructions, particularly in the control of dental plaque, as well as assess the effectiveness of the reinforcement of the same instructions. Methods: A quasi-experimental study was conducted at the University Clinic of the Portuguese Catholic University (UCP in Viseu-Portugal from January to June 2012. Three different assessments were performed with 30 participants using the O’Leary Plaque Index and a questionnaire on oral health behavior, with a one-month interval between each assessment. In the first assessment, all participants received the same instructions of oral hygiene and the O’Leary Plaque Index registration and the application of the questionnaire were performed; in the second assessment, a new registration of the O’Leary Index was made, but only the experimental group (n=16 received the reinforcement of oral health instructions, and in the third assessment, a new registration of the O’Leary Plaque Index was made for all the individuals (n=30. Results: Both control and experimental groups showed a decrease in the O’Leary Plaque Index, but the latter showed a more significant decrease in the last assessment: 38.19% (n=16 vs. 69.57% (n=14, p <0.05. Regarding the frequency of toothbrushing, in the experimental group, 68.8% (n=11 brushed the teeth at least twice a day, while in the control group only 57.1% (n=8 performed the same frequency of toothbrushing. In this case, statistically significant differences were found between the two groups (p<0.05. Conclusion: Oral health promotion through oral hygiene instruction was effective in improving oral health behaviors, and, consequentely, the control of dental biofilm. doi:10.5020/18061230.2014.p117

Full Text Available OBJECTIVES: Oral mucositis is a complication frequently associated with hematopoietic stem cell transplantation, decreasing a patient's quality of life and increasing the occurrence of opportunistic infections. The purpose of this study was to determine the incidence and severity of oral mucositis and to assess the correlation of this disease with the oral health of an individual at the time of hematopoietic stem cell transplantation. METHODS: Before transplantation, patients' oral health and inflammatory conditions were determined using the gingival index and the plaque index, which are based on gingival bleeding and the presence of dental plaque, respectively. Additionally, the dental health status was determined using the decayed, missing, and filled teeth index. The monitoring of oral mucositis was based on the World Health Organization grading system and was performed for five periods: from Day 0 to D+5, from D+6 to D+10, from D+11 to D+15, from D+16 to D+20, and from D+21 to D+30. RESULTS: A total of 97 patients (56% male and 44% female who underwent hematopoietic stem cell transplantation at the Hospital das Clinicas da Faculdade de Medicina da Universidade de Sao Paulo between January 2008 and July 2009 were prospectively examined. The incidence of ulcerative mucositis was highest from days +6 to +10 and from days +11 to +15 in the patients who underwent autologous and allogeneic hematopoietic stem cell transplantation, respectively. CONCLUSION: The data, including the dental plaque and periodontal status data, showed that these oral health factors were predictive of the incidence and severity of oral mucositis in a cohort of patients with similar conditioning regimens before hematopoietic stem cell transplantation.

Full Text Available This article reviews some of the more common benign oral papules and nodules of oral mucosa with emphasis on their etiology, epidemiology, clinical presentation, histopathology, and treatment. These lesions include mucocele, traumatic fibroma, epulis, pyogenic granuloma, oral papilloma, oral warts, lymphangioma, hemangioma, lipoma, oral nevi and some soft tissue benign tumors. These benign lesions must be separated clinically and histologically from precancerous and malign neoplastic lesions. Accurate clinico-pathological diagnosis is mandatory to insure appropriate therapy.

Aphthous ulcers are painful ulcerations located on the mucous membrane, generally in the mouth, less often in the genital area. Three clinical forms of aphthous ulcers have been described: minor aphthous ulcers, herpetiform aphthous ulcers and major aphthous ulcers. Many other conditions presenting with oral bullous or vesiculous lesions orulcerations and erosions can be mistaken for aphthous ulcers. Currently, treatment of aphthous ulcers is palliative and symptomatic. Topical treatments (topical anesthetics, topical steroids and sucralfate) are the first line therapy. Recurrent aphthous stomatitis (RAS) is defined by the recurrence of oral aphthous ulcers at least 4 times per year. RAS is often idiopathic but can be associated with gastro-intestinal diseases (i.e. celiac disease, inflammatory bowel diseases), nutritional deficiencies (iron, folates…), immune disorders (HIV infection, neutropenia) and rare syndromes. Behçet's disease is a chronic, inflammatory, disease whose main clinical feature is recurrent bipolar aphthosis. Colchicine associated with topical treatments constitutes a suitable treatment of most RAS. Thalidomide is the most effective treatment of RAS but its use is limited by frequent adverse effects. Oral ulcers can be related to a wide range of conditions that constitute the differential diagnoses of aphthous ulcers. Oral ulcers are classified into three main groups: acute ulcers with abrupt onset and short duration, recurrent ulcers (mainly due to postherpetic erythema multiforme) and chronic ulcers (with slow onset and insidious progression). Acute oral ulcers are due to trauma, bacterial infections (including acute necrotizing ulcerative gingivitis), deep fungal infection, gastro-intestinal (namely inflammatory bowel disease) or systemic diseases. Chronic oral ulcers may be drug-induced, or due to benign or malignant tumors. Every oral solitary chronic ulcer should be biopsied to rule out squamous cell carcinoma. A solitary palatal ulcer
This discussion of oral contraceptives (OCs) presents information on the following: types of steroidal contraception OCs, injectable contraceptive agents, implants, intravaginal rings, IUD bearing steroids, male pills, intracervical devices, contraceptive bracelets, and intranasal administration of hormones); guidelines for adolescent usage (why adolescents use OCs, common medical concerns, assessment, prescribing, educating for user effectiveness, and the length of time that the adolescent can use OCs); the marketing of OCs; attitudes toward OCs; the effect of OCs on insulin requirements in diabetes; mortality among OC users; assessing new knowledge of mortality trends and OCs; beneficial and adverse effects; sexual and psychological response to OCs; chromosomal abnormalities and OCs; ectopic pregnancies and the progestogen only pill; liver tumors and OCs; cancer and OCs; eye conditions and OCs; and postpill amenorrhea and infertility. Most adolescents choose OCs as their initial contraceptive method because it is probably the only method of which they have much knowledge. Most adolescents lack the needed level of sexual maturity and sexual sophistication to pause to insert a diaphrage or to use a condom. Another attraction of OCs is reliability. At this time 12 major companies based in 8 countries (excluding China) produce and market OCs. Basically either of 2 estrogens, ethinyl estradiol and mestranol, are used in combination with about 6 different progestogens. Attitudes vary greatly and range from total acceptance to total rejection. Despite some negative views about OC, 32.2% of Australian women in childbearing years are using OCs indicating a high degree of acceptance. The new data available indicate strongly that the hazards of using OCs are somewhat greater than previously suspected. In 1977 the Royal College of General Practitioners reported a death rate from circulatory disease which was in OC users 4.7 times that of women who had never used OCs. The

Pigmented oral lesions compose a large number of pathological entities, including exogenous pigmentat oral tattoos, such as amalgam and graphite tattoos. We report a rare case of a graphite tattoo on the palate of a 62-year-old patient with a history of pencil injury, compare it with amalgam tattoos, and determine the prevalence of oral tattoos in our Oral Pathology Service. We also compare the clinical and histological findings of grafite and amalgam tattoos. Oral tattoos affect women more frequently in the region of the alveolar ridge. Graphite tattoos occur in younger patients when compared with the amalgam type. Histologically, amalgam lesions represent impregnation of the reticular fibers of vessels and nerves with silver, whereas in cases of graphite tattoos, this impregnation is not observed, but it is common to observe a granulomatous inflammatory response, less evident in cases of amalgam tattoos. Both types of lesions require no treatment, but in some cases a biopsy may be done to rule out melanocytic lesions. PMID:26632800

The predominant diet fed to captive carnivores in North America consists of ground meat formulated to provide full nutritional requirements. However, this ground meat diet completely lacks the mechanical properties (i.e., toughness and hardness) of the foods these animals would consume in the wild. The goal of this study is to evaluate the effect of captivity on oral health by comparing the prevalence of periodontal disease and dental calculus accumulation in wild and captive lions and tigers (Panthera leo and Panthera tigris), and to also correlate oral health with cranial morphology in these specimens. To achieve this, 34 adult lion and 29 adult tiger skulls were scored for the presence and extent of dental calculus and periodontal disease. These oral health scores were also compared to cranial deformations examined in a previous study. We found that the occurrence and severity of calculus buildup and periodontal disease was significantly higher in captive felids compared to their wild counterparts. Further, higher calculus accumulation occurred on the posterior teeth when compared to the anterior teeth, while an opposite trend for periodontal disease was observed. We also found a significant correlation between oral health and cranial morphology of lions and tigers. The results suggest that food mechanical properties are significant factors contributing to oral health in felids. PMID:27473998
Full Text Available Acute leukaemia is the most common form of chilhood cancer. The aim of this paper was to underline the importance of oral manifestations in children with acute leukaemia. The disease and its treatment can directly or indirectly affect oral health. Oral manifestations are gingival inflammation and enlargement. Leukaemic cells are capable of infiltrating the gingiva and the deeper periodontal tissues which leads to ulceration and infection of oral tissues. Gingival bleeding is a common sign in patients with leukaemia. Symptoms include local lymphadenopathy, mucous membrane Petechiae and ecchymoses. Cytotoxic drugs have direct effects like mucositis, involving atrophy, desquamation and ulceration of the mucosa, with increasing the risk for local and systemic infections. Leukaemia can directly influence dental care and dental treatment, while oral lesions may have life-threatening consequences. Knowledge and skills among dentists may also not be adequate to treat children with acute leukaemia. It is therefore imperative that all stomatologists be aware of dental problems that occur in leukaemia in order to be able to effectively carry out appropriate measures to mitigate these problems.

It is very common in Southeast Asia but has started to spread to Europe and North America. OSF can lead to squamous cell carcinoma, a risk that is further increased by concomitant tobacco consumption. OSF is a diagnosis based on clinical symptoms and confirmation by histopathology. Hypovascularity leading to blanching of the oral mucosa, staining of teeth and gingiva, and trismus are major symptoms. Major constituents of betel quid are arecoline from betel nuts and copper, which are responsible for fibroblast dysfunction and fibrosis. A variety of extracellular and intracellular signaling pathways might be involved. Treatment of OSF is difficult, as not many large, randomized controlled trials have been conducted. The principal actions of drug therapy include antifibrotic, anti-inflammatory, and antioxygen radical mechanisms. Potential new drugs are on the horizon. Surgery may be necessary in advanced cases of trismus. Prevention is most important, as no healing can be achieved with available treatments.

Full Text Available Squamous cell carcinoma of the oral region (OSCC is one of the most common and highly aggressive malignancies worldwide, despite the fact that significant results have been achieved during the last decades in its detection, prevention and treatment. Although many efforts have been made to define the molecular signatures that identify the clinical outcome of oral cancers, OSCC still lacks reliable prognostic molecular markers. Scientific evidence indicates that transition from normal epithelium to pre-malignancy, and finally to oral carcinoma, depends on the accumulation of genetic and epigenetic alterations in a multistep process. Unlike genetic alterations, epigenetic changes are heritable and potentially reversible. The most common examples of such changes are DNA methylation, histone modification, and small non-coding RNAs. Although several epigenetic changes have been currently linked to OSCC initiation and progression, they have been only partially characterized. Over the last decade, it has been demonstrated that especially aberrant DNA methylation plays a critical role in oral cancer. The major goal of the present paper is to review the recent literature about the epigenetic modifications contribution in early and later phases of OSCC malignant transformation; in particular we point out the current evidence of epigenetic marks as novel markers for early diagnosis and prognosis as well as potential therapeutic targets in oral cancer.

The usefulness of pronunciation teaching is a widely debated subject in the language teaching world. Some of the current research would suggest that teachers can make little or no difference in improving their students’pronunciation. In contrast, there is research that indicates that the teacher can make a noticeable difference if certain criteria, such as the teaching of suprasegmen⁃tals and the linking of pronunciation with oral practice, are fulfilled. This paper intends to address the practical challenges related to integrating pronunciation into oral communication. First, the central difficulty in integrating pronunciation into the speaking classroom is described. Next, all-skill principles to guide the incorporation of pronunciation into oral communication courses are suggested. Finally, possible implementation strategies that can be applied to a wide variety of instructional settings are explored.
A focus often exists in dental practice on the maintenance and management of the dentition and the periodontium, however, conditions of the oral mucosa and orofacial pain can cause significant problems for older patients. Oral mucosal conditions are more prevalent in older patients and many orofacial pain disorders, such as burning mouth syndrome and trigeminal neuralgia, are more common in patients over the age of 50 years. Although these conditions may not be routinely managed in general practice, identification of these patients in primary care and appropriate referral will lead to more prompt and effective treatment. CLINICAL RELEVANCE: Dental practitioners need to be able to identify what is considered to be within the normal physiological limits of the ageing oral tissue and hence what is abnormal and requires further investigation to facilitate appropriate referral.

Full Text Available Oral cancers are malignant neoplasms that affect the mouth. Oral cancer remains a major personal tragedy and public health problem. There is a very high incidence of oral cancer in Southern Asia. In India, the oral cavity is the most common site for cancer. The majority of oral squamous cell carcinomas are related to tobacco, areca nut / betel quid chewing, alcoholism. Control of oral potentially malignant diseases will only be achieved by effective and comprehensive primary and secondary prevention by recognizing that the risk factors are common to most other diseases.

An oral drug delivery system using proteinoid microspheres is discussed with respect to its unique dependence on pH. It has been found that certain drugs such as insulin and heparin can be encapsulated in proteinoid spheres at stomach pH's (1-3). These spheres also dissemble at intestinal pH's (6-7) releasing the drug for absorption. Using this technique low molecular weight heparin and human growth hormone have been orally delivered successfully to several animal species. Future work has been proposed to study the interaction and binding of the specific drugs with synthesized oligopeptides.
Conclusion: The cytomorphometric changes observed in samples from oral SCC and oral leukoplakia were consistent with the current diagnostic features. Hence, the semi-automated cytomorphometric analysis of oral mucosal cells can be used as an objective adjunct diagnostic tool in the diagnosis of these lesions.

Last May, the New York State Dental Association and the New York State Dental Foundation convened the first "Oral Health Stakeholders' Summit on the Future of Special Needs Dentistry, Hospital Dentistry and Dental Education." The summit was chaired by David J. Miller, then NYSDA President Elect, and Carl H. Tegtmeier, then chair of the NYSDA Council on Dental Health Planning and Hospital Dentistry. It brought together experts, called to frame the issues and provide information necessary for a reasoned response. And it sought input from attendees to develop recommendations to ensure that patients with intellectual and developmental disabilities, as well as an aging population with Alzheimer's disease and dementia, have access to appropriate oral health care in the years ahead. Over 100 participants, representing dentistry, hospital training programs, third-party payers, state government offices and related patient support associations, attended the two-day event in Albany. They focused on the impact of reductions in funding, the transition of Medicaid services into a managed care model, a loss of service providers and the need for expanded training programs. They heard from speakers epresenting a broad spectrum of those involved in he oral health care of patients with intellectual and evelopmental disabilities, the Alzheimer's Association, dental educators and researchers, hospital dentistry and the benefits industry, whose presentations focused on a looming oral health crisis threatening access to dental care for patients with disabilities.

Oral malignant melanoma is a rare disease. The common sites of its occurrence are the palate and gingiva with the maxillary arch being affected 80% of the time. Because of their presence at relatively obscure areas in the oral cavity, most of the malignant melanomas of the oral cavity are diagnosed at a late stage. These lesions are associated with poor prognosis. The dental clinician must therefore carefully examine the head, neck, and oral cavity, and any pigmented lesion that may ex...

Full Text Available Paracoccidioidomycosis (PCM is a deep mycosis with primary lung manifestations that may present cutaneous and oral lesions. Oral lesions mimic other infectious diseases or even squamous cell carcinoma, clinically and microscopically. Sometimes, the dentist is the first to detect the disease, because lung lesions are asymptomatic, or even misdiagnosed. An unusual case of PCM with 5 months of evolution presenting pulmonary, oral, and cutaneous lesions that was diagnosed by the dentist based on oral lesions is presented and discussed.

Oral cancer is one of the most common cancers worldwide. Despite of various advancements in the treatment modalities, oral cancer mortalities are more, particularly in developing countries like India. This is mainly due to the delay in diagnosis of oral cancer. Delay in diagnosis greatly reduces prognosis of the treatment and also cause increased morbidity and mortality rates. Early diagnosis plays a key role in effective management of oral cancer. A rapid diagnostic technique can greatly aid...

Full Text Available Nutrition represents a summation of intake, absorption, storage and utilization of foods by the tissues. Oral tissues are one of the most sensitive indicators of nutritional state of the body. Nutritional deficiencies are associated with changes in the integrity (health and appearance of the oral structures/ tissues and these changes are frequently the first clinical signs of deficiency. Nutrition affects oral health and oral health affects nutrition. The effects of malnutrition can be seen in the oral structures in all stages of human growth and development from conception to old age. The consequence of certain oral diseases may compromise the nutrition by affecting the intake and mastication particularly in some vulnerable groups like people with severe caries, severe oral ulceration, advanced periodontal disease and the resulting edentulousness. The HIV pandemic has added another dimension to the issue of nutrition and oral health. Oral lesions are some of the earliest lesions seen in HIV/AIDS and 90% of HIV/AIDS patients will have oral lesions at a point in the course of the disease. These oral lesions are painful; disturb food intake and mastication thereby further compromising the nutrition of the affected individuals. In Africa, particularly the Sub-Saharan Africa, the burden of poverty, economic downturn and the HIV pandemic have added another dimension to the issue of food availability and nutrition. Malnutrition is a real problem in this area. This paper will examine the effects of compromised nutrition on oral health and the reverse.

Primary mucosal leishmaniasis is a rare infectious disease, particularly in immunocompetent patients. We present a 50-year-old patient with a 6-week history of a painful lesion of the left buccal mucosa that mimicked cancer. The exophytic lesion looked invasive, and we took an incisional biopsy specimen to exclude cancer. The diagnosis of leishmaniasis was unexpected, and the patient was successfully treated with amphotericin B for five weeks. After five months the patient had a visceral recurrence. Chronic exophytic and ulcerated mucosal lesions that do not heal within 3-4 weeks should be regarded as the first signs of oral cancer, but primary oral leishmaniasis can easily mimic it.

Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity. PMID:10518916

Metastatic lesions to the oral region are uncommon and account for approximately 1% of all malignant oral tumors. In 25% of the cases, oral metastases are found to be the first sign of the metastatic spread; and in 23% of the cases, it is the first indication of an undiscovered malignancy at a distant site. Metastases to oral soft tissues are even less frequent than jaw bones. Because of its rarity, the clinical presentation of a metastatic lesion in the oral cavity can be deceiving, leading ...

Despite the common prevalence of cutaneous psoriasis, the existence of manifestations in the oral cavity is subject to controversy. In this article, dermatologic psoriasis is reviewed, and a patient with generalized, symptomatic oral mucosal erythema resembling atrophic candidiasis synchronous with flare of chronic skin psoriasis is described. Diagnostic work up and therapeutic response supported that these mucosal findings were the oral counterpart of cutaneous disease. Dental providers should be familiar with the signs and symptoms of oral psoriasis, institute appropriate preventive measures, and provide palliation directed at symptomatic oral changes of psoriasis.

AIM: To investigate the pathological characteristics and carcinogenesis mechanism of benign lymphoadenosis of oral mucosa (BLOM).METHODS: The expressions of Ki-67, CD34 and apoptosis were evaluated by immunohistochemical SP staining in 64 paraffin-embedded tissue samples. Of them, 9 were from BLOM with dysplasia, 15 from BLOM without dysplasia,15 from oral squamous cell carcinoma (OSCC), 15 from oral precancerosis, and 10 from normal tissues. Cell proliferation, apoptosis and angiogenesis of tissue samples were also analyzed.RESULTS: The expression of Ki-67 in BLOM with dysplasia,oral precancerosis and OSCC was significantly higher than in BLOM without dysplasia and normal mucosa. The microvascular density (MVD) in BLOM with and without dysplasia, oral precancerosis, and OSCC was significantly higher than in normal mucosa. Apoptosis in BLOM and oral precancerosis was significantly higher than in OSCC and normal mucosa.CONCLUSION: Benign lymphoadenosis of oral mucosa has potentialities of cancerization.
Full Text Available Diabetes mellitus is a group of metabolic disorders characterized by abnormal secretion and metabolic action of insulin. Hyperglycemia, the key feature of this endocrine disorder causes multisystem damage leading to untoward effects in various tissues collectively referred to as "Diabetic complications". Diabetes alters the oral health to a great extent. Indeed, periodontitis has been reported as the sixth complication of this disease. This article gives an overview of the oral effects of diabetes with an emphasis on periodontal disease and its relationship with cardiovascular disorders and pre-term birth. Dental considerations for management of these patients and recent advances in the dental field with respect to diabetes are also highlighted.
Full Text Available Myiasis, a term first introduced by Hope (1840, refers to the invasion of tissues and organs of animals and human wounds and certain body cavities by the dipteran larvae which manifests as subcutaneous furunculoid or boillike lesions. Oral myiasis is a rare pathology and a risk to the patient′s life. Higher incidence is seen in rural areas affecting the tropical and sub-tropical zones of Africa and America. Myiasis affecting the oro-dental complex is rare. Here is a case report of oral myiasis in an 18-year-old male patient who is mentally challenged with anterior open bite, incompetent lips, and periodontal disease. The lesion was treated with turpentine oil, which forced larvae out and irrigated with normal saline solution. Follow-up examination revealed complete remission and healing of the lesion.

Direct oral anticoagulants (DOAC) are recommended for stroke prevention in atrial fibrillation and for the treatment of venous thromboembolism. However, they are associated with hemorrhagic complications. Management of DOAC-induced bleeding remains challenging. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain. Therapeutic options also include antidotes: idarucizumab, antidote for dabigatran, has been approved for use whereas andexanet alpha, antidote for anti-Xa agents, and aripazine, antidote for all DOAC, are under development. Other options include hemodialysis for the treatment of dabigatran-associated bleeding and administration of oral charcoal if recent DOAC ingestion. DOAC plasma concentration measurement is necessary to guide DOAC reversal. We propose an update on DOAC-associated bleeding, integrating the availability of dabigatran antidote and the critical place of DOAC concentration measurements. PMID:27297642

The majority of oral diseases present as growths and masses of varied cellular origin. Such masses may include simple hyperplasia, hamartoma, choristoma, teratoma, benign or malignant neoplasms. The distinguishing features of hamartomatous lesions are not certain, and often these non-neoplastic masses are indiscreetly denoted as neoplasms without weighing their pathology or biological behaviour. Essentially, understanding the dynamics of each of these disease processes forms an integral part ...
Full Text Available Abstract Background In western Sweden, the aim was to study the associations between oral health variables and total and central adiposity, respectively, and to investigate the influence of socio-economic factors (SES, lifestyle, dental anxiety and co-morbidity. Methods The subjects constituted a randomised sample from the 1992 data collection in the Prospective Population Study of Women in Gothenburg, Sweden (n = 999, 38- > =78 yrs. The study comprised a clinical and radiographic examination, together with a self-administered questionnaire. Obesity was defined as body mass index (BMI > =30 kg/m2, waist-hip ratio (WHR > =0.80, and waist circumference >0.88 m. Associations were estimated using logistic regression including adjustments for possible confounders. Results The mean BMI value was 25.96 kg/m2, the mean WHR 0.83, and the mean waist circumference 0.83 m. The number of teeth, the number of restored teeth, xerostomia, dental visiting habits and self-perceived health were associated with both total and central adiposity, independent of age and SES. For instance, there were statistically significant associations between a small number of teeth ( Conclusions Associations were found between oral health and obesity. The choice of obesity measure in oral health studies should be carefully considered.
Full Text Available Aims: To determine the level of oral cancer awareness and knowledge among patients referred to the Department of Oral and Maxillofacial Radiology in Central Anatolia. Settings and Design: The study was conducted with 1,125 patients who applied to the school of dentistry for routine dental examinations. The authors collect information with a 20-item written questionnaire from the participants about oral cancer risk factors, epidemiology, etiology, and signs and symptoms. Statistical Analysis: Descriptive statistics of demographic variables and other data were reported as means and percentages. Statistical analysis was performed by means of SPSS +11.0 statistical package. Results: Overall, only 48.9% of all patients showed awareness of oral cancer, with awareness especially poor among lower socioeconomic groups. Awareness of oral cancer risk factors and signs and symptoms did not vary significantly between men and women (P > 0.5; however, older participants (aged 40-64 years were more familiar with oral cancer signs than younger participants. More than half of all participants (56.8% were unaware of the common clinical presentations of oral cancer. Conclusions: The results of this survey showed knowledge regarding oral cancer to be quite low. Thus, educational programs are needed to increase public awareness about oral cancer, and dentists should request patients undergo examinations for oral cancer to ensure early detection.

A human oral microbiota is the ecological community of commensal, symbiotic, and pathogenic microorganisms found in human oral cavity. Oral microbiota exists mostly in the form of a biofilm and maintains a dynamic ecological equilibrium with the host body. However, the disturbance of this ecological balance inevitably causes oral infectious diseases, such as dental caries, apical periodontitis, periodontal diseases, pericoronitis, and craniofacial bone osteomyelitis. Oral microbiota is also correlated with many systemic diseases, including cancer, diabetes mellitus, rheumatoid arthritis, cardiovascular diseases, and preterm birth. Hence, oral microbiota has been considered as a potential biomarker of human diseases. The "Human Microbiome Project" and other metagenomic projects worldwide have advanced our knowledge of the human oral microbiota. The integration of these metadata has been the frontier of oral microbiology to improve clinical translation. By reviewing recent progress on studies involving oral microbiota-related oral and systemic diseases, we aimed to propose the essential role of oral microbiota in the prediction of the onset, progression, and prognosis of oral and systemic diseases. An oral microbiota-based prediction model helps develop a new paradigm of personalized medicine and benefits the human health in the post-metagenomics era. PMID:27051943

Malnutrition affects the oral health and a poor oral health in turn, may lead to malnutrition. This interdependent relationship sees good nutritional health, thus promoting good oral health and vice versa. Malnutrition may alter the homeostasis, which can lead to disease progression of the oral cavity, reduce the resistance to the microbial biofilm and reduce the capacity of tissue healing. It may even affect the development of the oral cavity. Protein-energy malnutrition occurs when there is a deficiency of protein, energy foods or both, which are relative to a body's need. Studies have suggested that enamel hypoplasia, salivary gland hypofunction and saliva compositional changes may be the mechanisms through which the malnutrition is associated with caries, while an altered eruption timing may create a challenge in the analysis of the age specific caries rates. This paper gives an insight on the relationship of the malnutrition and the protein-energy malnutrition with the oral health status. PMID:23449967
Oral English has always been a major problem for Chinese Eng-lish as Second Language (ESL) students. In fact, most Chinese students do not practice oral English very often, while their reading and writing abilities have gained rapid progress. However, language is a system that includes both words and sounds for communicative use, neither of which can be neglected. While there are hundred forms of classroom activities, the usage of most effective o-ral activities has become a serious issue that an ESL teacher should focuses on. The review is based on research results on effective oral ESL activities. The research results on the factors should be considered when selecting/plan-ning oral activities and applying oral activities ESL classes.

Oral lichen planus (OLP) and oral lichenoid reaction (OLR) are clinically and histopathologically similar diseases. Whereas OLP is a consequence of T cell mediated autoinflammatory process to a still unknown antigen, OLR might be caused by drugs, dental restorative materials and dental plaque. Pubmed was searched and 24 publications published over the last three years regarding etiology, diagnosis and malignant alteration were included in this study. Patients with OLR who have amalgam fillings near lesions should have them replaced, i.e. when possible they should be referred to patch test, as well as when drug-induced OLR are suspected. OLR lesions induced by drugs should disappear when the offending drug has been discontinued. Histology finding in OLR consists of more eosinophils, plasma cells and granulocytes in comparison to OLP lesions. Furthermore, OLP lesions showed more p53, bcl-2 and COX-2 positivity when compared to OLR. OLP is characterized by infiltration, atrophic epithelium, rete pegs and Max Joseph spaces, while deep infiltration into connective tissue and hyperkeratosis were the criteria for making the diagnosis of OLR. The number of degranulated mastocytes in the reticular layer, as well as the number of capillaries was higher in OLR in comparison to OLP. It seems that OLR are more prone to malignant alteration in comparison to OLP. PMID:27017728

The study involved biopsy samples from 47 patients with oral cancer of which 11 patients had cancer of tongue, 17 of buccal mucosa and 19 of alveolus. The results of excitation and emission spectroscopy at several wavelengths (280 nm less than or equal to (lambda) exless than or equal to 460 nm; 340 nm less than or equal to (lambda) em less than or equal to 520 nm) showed that at (lambda) ex equals 337 nm and 400 nm the mean value for the spectrally integrated fluorescence intensity [(Sigma) (lambda ) IF((lambda) )] from the normal tissue sites was about a factor of 2 larger than that from the malignant tissue sites. At other excitation wavelengths the difference in (Sigma) (lambda ) IF((lambda) ) was not statistically significant. Similarly, for (lambda) em equals 390 nm and 460 nm, the intensity of the 340 nm band of the excitation spectra from normal tissues was observed to be a factor of 2 larger than that from malignant tissues. Analysis of these results suggests that NADH concentration is higher in normal oral tissues compared to the malignant. This contrasts with our earlier observation of an reduced NADH concentration in normal sites of breast tissues vis a vis malignant sites. For the 337 nm excited emission spectra a 10-variable MVLR score (using (Sigma) (lambda ) IF((lambda) ) and normalized intensities at nine wavelengths as input parameters) provided a sensitivity and specificity of 95.7% and 93.1% over the sample size investigated.

Food allergy is a potentially life-threatening condition with no approved therapies, apart from avoidance and injectable epinephrine for acute allergic reactions. Oral immunotherapy (OIT) is an experimental treatment in which food-allergic patients consume gradually increasing quantities of the food to increase their threshold for allergic reaction. This therapy carries significant risk of allergic reactions. The ability of OIT to desensitize patients to particular foods is well-documented, although the ability to induce tolerance has not been established. This review focuses on recent studies for the treatment of food allergies such as cow's milk, hen's egg, and peanut. PMID:26617227

Full Text Available Osteosarcoma is the most common primary malignant mesenchymal tumor, accounting for approximately 20% of sarcomas, with 5% incidence in the jaws. They present various clinical and histological aspects as well as variable disease prognosis and outcome. About 50% of all osteosarcomas are osteoblastic, 25% fibroblastic, 25% chondroblastic. Metastasis of osteosarcoma in the oral cavity is rare, and very few cases have been described so far in the literature. This article presents a metastatic case of chondroblastic osteosarcoma in the mandibular right-attached gingiva arising from 4 th rib. This case report further suggests that chondroblastic osteosarcoma has poor prognosis.

The ability to generate 3-dimensional volumetric images of the maxillofacial area has allowed surgeons to evaluate anatomy before surgery and plan for the placement of implants in ideal positions. However, the ability to transfer that information to surgical reality has been the most challenging part of implant dentistry. With the advent of computer-assisted surgery, the surgeon may now navigate through the entire implant procedure with extremely high accuracy. A new portable laptop navigated system for oral implantology is discussed as an adjunct for complex implant cases. PMID:16569960
Erectile disfunction (E. D.) is more common in older men but may affect younger men too. Diabetes mellitus, coronary heart disease and hypertension are often associated with E. D. The majority of the patients are treated medically for erectile dysfunction and, recently, oral therapy has become most important since Viagra has been approved. New phosphodiesterase blockers are in preclinical evaluation since then. Phentolamine and apomorphine will become available soon for the treatment of E. D. It is important to know about the etiology of E. D. as well as the mechanisms by which drugs may improve erection in order to decide which drug is appropriate for a particular patient. PMID:10746289

Full Text Available Abstract Background Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted. Methods/design This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P, on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg to that of a historical control group. The study has been approved by IRBs (ethics committees of all involved sites. Results will be disseminated through publications and presentations at scientific meetings. Discussion The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study
The advent of the theory of communicative competence raised new issues for language teaching and testing. The importance of communicative ability is emphasized in language teaching. Therefore test that could reflect a student's communicative competence need to be constructed. Communicative testing is such a potentially effective approach.This paper is concerned with the theoretical basis of communicative testing, its distinguishing features and the construction of oral proficiency tests, so as to demonstrate how the theory of communicative testing is built into practical tests.

Age changes affect the oral mucosa (the protective lining of the oral cavity), but few of these have been studied objectively. The aim of this study was to quantitatively analyse a number of morphometric parameters of the ageing oral mucosa. The fractal dimension of the epithelial connective tissue interface (ECTI) was estimated in 42 samples of normal buccal mucosa to correlate any changes in their irregularity to the age of the individuals. Morphometric parameters extracted from theoretical...

This paper discusses the development, implementation, and evaluation of a semi-direct test of oral proficiency: the Rhetorical Task Examination (RTE). Many of the commonly used speaking instruments assess oral proficiency in terms of either discrete linguistic components-fluency, grammar, pronunciation, and vocabulary-or in terms of a single, global ability rating. The RTE proposes a compromise approach to rating oral skills by having two scales: one which ascertains the functional ability to...

Oral infections caused by yeast of the genus Candida and particularly Candida albicans (oral candidoses) have been recognised throughout recorded history. However, since the 1980s a clear surge of interest and associated research into these infections have occurred. This has largely been due to an increased incidence of oral candidosis over this period, primarily because of the escalation in HIV-infection and the AIDS epidemic. In addition, changes in medical practice leading to a greater use...

The purpose of this article was to draw attention to a periimplantitis-like clinical presentation of oral malignancy around dental implants, a phenomenon that may develop without any associated risk factors for oral cancer. Such a benign appearance of oral malignancy may lead to delay in the diagnosis and initiation of ensuing treatment. Therefore, chronic nonhealing inflammatory lesions around dental implants should be considered as highly suspicious. PMID:26803178

Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

Introduction The management of oral mucositis is a challenge, due to its complex biological nature. Over the last 10 years, different strategies have been developed for the management of oral mucositis caused by chemotherapy in cancer patients. Material and Methods An exhaustive search was made of the PubMed-Medline, Cochrane Library and Scopus databases, crossing the key words “oral mucositis”, “prevention” and “treatment” with the terms “chemotherapy” and “radiotherapy” by means of the boolean operators “AND” and “NOT”. A total of 268 articles were obtained, of which 96 met the inclusion criteria. Results Several interventions for the prevention of oral mucositis, such as oral hygiene protocols, amifostine, benzidamine, calcium phosphate, cryotherapy and iseganan, among others, were found to yield only limited benefits. Other studies have reported a decrease in the appearance and severity of mucositis with the use of cytoprotectors (sucralfate, oral glutamine, hyaluronic acid), growth factors, topical polyvinylpyrrolidone, and low power laser irradiation. Conclusions Very few interventions of confirmed efficacy are available for the management of oral mucositis due to chemotherapy. However, according to the reviewed literature, the use of palifermin, cryotherapy and low power laser offers benefits, reducing the incidence and severity of oral mucositis – though further studies are needed to confirm the results obtained. Key words:Chemotherapy-Induced Oral Mucositis Treatment. PMID:27034762
The individual oral statement is human story based on experience. The personal experience forms unconsciousness which appears in a form of oral statement by ego that doesn't want to lose existence. Thus, the process which exposes a tormented hearts is the objectification of oneself. Through this step, oral person attains a healing. If this sort of individual oral is accrued, the undeserved personal affairs could be a history. In case of Hansen's disease patient, She could escape from negative understanding about herself and the world. Furthermore, She kept formating her values about meaningful life and future oriented value. Also, She wants to keep a record of her life. She comes to know that what she denied is actually what she should surmount over oral statement. As a result, She could attains a healing for oneself through oral statement. The oral statement made her look into she's problems. Therefore, oral statement is a self-realization. Through this, person could know what the problem is and solution. This research is about only one person, so there is need for more cases and studies. If this sort of individual oral statement is accrued, there could be a curative narration. This can suggest an curative alternative when we suffer from problem of life. The merit of this research is rendering this possibility. PMID:24005645

We explore Aboriginal oral traditions that relate to Australian meteorite craters. Using the literature, first-hand ethnographic records, and fieldtrip data, we identify oral traditions and artworks associated with four impact sites: Gosses Bluff, Henbury, Liverpool, and Wolfe Creek. Oral traditions describe impact origins for Gosses Bluff and Wolfe Creek craters and non-impact origins of Liverpool and Henbury craters, with Wolfe Creek stories having both impact and non-impact origins. Three impact sites that are believed to have formed during human habitation of Australia - Dalgaranga, Veevers, and Boxhole - do not have associated oral traditions that are reported in the literature.

The oral carriage rate of Candida in healthy humans ranges from 40% to 60%. However for a prolonged period, the oral candidal prevalence in humans was documented essentially using data from studies in the West as their prevalence in inhabitants in different regions of the world, including Asia was not known. Yet, recent reports from a number of studies indicate the quality, quantity and prevalence of oral yeasts differ between Asia and other regions for reason that are still unclear. This mini review on such data from Asian studies on oral carriage of Candida provides another intriguing facet of the behavior of this ubiquitous yeast.

Oxidative species, including reactive oxygen species (ROS), are components of normal cellular metabolism and are required for intracellular processes as varied as proliferation, signal transduction, and apoptosis. In the situation of chronic oxidative stress, however, ROS contribute to various pathophysiologies and are involved in multiple stages of carcinogenesis. In head and neck cancers specifically, many common risk factors contribute to carcinogenesis via ROS-based mechanisms, including tobacco, areca quid, alcohol, and viruses. Given their widespread influence on the process of carcinogenesis, ROS and their related pathways are attractive targets for intervention. The effects of radiation therapy, a central component of treatment for nearly all head and neck cancers, can also be altered via interfering with oxidative pathways. These pathways are also relevant to the development of many benign oral diseases. In this review, we outline how ROS contribute to pathophysiology with a focus toward head and neck cancers and benign oral diseases, describing potential targets and pathways for intervention that exploit the role of oxidative species in these pathologic processes.

Full Text Available Halitosis is a widespread condition and believed to affect one-quarter of the population around the world; also, most people have this condition from time to time. Breath malodour may be an important factor in social communication, and therefore may be the origin of concern not only for a possible health condition but also for frequent psychological alterations, leading to social and personal isolation. The most conspicuous malodorous compounds are termed volatile sulphur compounds (VSCs, with hydrogen sulphide, methyl mercaptan, and dimethyl sulphide accounting for roughly 90% of the VSCs. A number of oral bacteria, especially Gram-negative anaerobic species found in the subgingival plaque, produce a diverse array of malodorous compounds as byproducts of their metabolism, including VSCs and short-chain organic acids. Assessment and management of halitosis is of paramount importance in enhancing the overall health; moreover, dentists play a significant role in combating halitosis by reducing the oral microbial stack. Thus, the aim of the present review was to describe the aetiological factors, assessment tools, and therapeutic approaches related to halitosis.
Neurocognitive decline and delirium, frailty, incontinence, falls, hearing and vision impairment, medication compliance and pharmacokinetics, skin breakdown, impaired sleep and rest are regarded as geriatric giants by gerontologists, geriatricians and nursing home staff. As these are all interrelated in the elderly, failure to act on one can impact on the others. However, the implications of poor oral health have for too long been ignored and deserve equal status. Mouth pain can be devastating for the elderly, compound psychosocial problems, frustrate carers and nursing home staff and disrupt family dynamics. As appearance, function and comfort suffer, so may a person's self-esteem and confidence. The contributing factors for poor oral health such as rapid dental decay, acute and chronic periodontal infections and compromised systemic health on a background of a dry mouth, coupled with xerostomia-inducing medications, reduced fine motor function, declining cognition and motivation will not only lead to an increase in both morbidity and mortality but also impact on quality of life.

Full Text Available High-risk human papillomaviruses (HR-HPV are considered necessary for the development of cervical cancer. Furthermore, there is no doubt that some types of oral squamous cell carcinoma are associated with HR-HPV. The epidemiology of oral HPV infections in healthy subjects remains unclear due to a lack of knowledge. The objective of this study was to investigate the epidemiology of human papillomavirus infections of the oral mucosa without pathology. A cross-sectional study was performed; samples from 390 women seeking prenatal care, Pap smears, family planning or gynecological diseases were studied. Oral cells were collected by direct swab sampling. Information regarding sociodemographic status, sexual behavior, infectious diseases, contraceptive history and tobacco and alcohol consumption were obtained through direct interviews. HPV and genotypes were detected by type-specific polymerase chain reaction. Our results revealed that 14% of the women studied had an oral HPV infection. Women ≤ 20 years of age had the highest HPV prevalence (24.5%. In total, seven genotypes were identified, including the high-risk genotypes 16, 18, 58 and 59 and the low-risk genotypes 6, 81 and 13, the latter of which is a type exclusive to oral mucosa. Sexual behavior was not associated with the presence of genital HPV types in the oral mucosa. Genital HPV types were present in the oral mucosa of women without associated clinical manifestations; however, sexual behavior was not associated with infection, and therefore others routes of transmission should be explored.

Full Text Available Objetivos: El afta es la lesión vesiculosa por antonomasia. Es difícil definir un afta verdadera ya que siempre se han llamado aftas a ulceraciones y erosiones de muy diverso origen. Este monográfico revisa la bibliografía más reciente acerca de la etiopatogenia, diagnóstico y tratamiento de éstas lesiones. Material y métodos: Se han revisado los estudios publicados desde 2000 hasta el 2008 mediante Pub-Med. Resultados: Las aftas se definen como un estado vesículo-ulceroso sobre una base eritematosa y fondo amarillento y pasan por una serie de periodos. La etiología aún sigue siendo desconocida. Se le atribuye una causa multifactorial y la literatura cuenta con numerosos estudios que sugieren por un lado, una posible base genética y por otro, la existencia de unos factores predisponentes como el trauma, el estrés, determinados alimentos, desequilibrio hormonal y tabaco; se habla incluso de otros posibles factores predisponentes como la actuación de virus o bacterias, deficiencias vitamínicas y factores inmunológicos. Existen tres formas clínicas de aparición que iremos describiendo tales como las aftas menores, aftas mayores y estomatitis aftosa herpetiforme además de una serie de síndromes que cursan con aparición de aftas a nivel oral y que por ello se denominan síndromes aftosos. El desconocimiento de la etiología y la naturaleza cíclica del proceso complican el tratamiento. Se han sugerido numerosas y diversas terapias contando con una amplia literatura al respecto pero con resultados inconsistentes. El tratamiento debe ser diseñado de forma individual y sintomática y persigue unos objetivos principales: acortar el proceso, evitar recidivas y disminuir los síntomas y tamaño de las úlceras durante el brote.Background: Aphthae is a common oral disorder whose definition is difficult due to the general denomination of several ulcerations and erosions as aphthae.

High level of periodontal problems of dental caries are frequently observed in mentally handicapped children. This group of patients presents various problems when they face dental treatments. Identification of such population and providing them affordable oral health care is the new concept. A systematic method for identification and screening of persons with mental retardation has been developed and is being followed. Cost and fear are the most commonly cited barriers to dental care. Physical or mental may lead to deterioration in self-care, and oral care state have a low priority. Risk factors are inter-related and are often barriers to oral health. With advancements in today's world sufficient information and support is available for each and every individual to lead a healthy life which include the access to the oral health care. Factors such as fear, anxiety and dental phobia plays a vital role in acceptance of dental care and also the delaying of dental care. Lack of knowledge of oral and dental disease, awareness or oral need, oral side-effects of medication and organization of dental services are highlighted in the literature. All health personnel should receive training to support the concept of primary oral health care. Training about dealing with such mentally handicapped people should be addressed urgently among the health professionals. PMID:25738098

Previous studies have used cryotherapy for the treatment of oral precancers including oral leukoplakia (OL) and oral verrucous hyperplasia (OVH) as well as oral cancers including oral verrucous carcinoma (OVC) and oral squamous cell carcinoma (OSCC). Cryotherapy is a method that locally destroys lesional tissues by freezing in situ. It can be carried out by either an "open" or a "closed" system. Lesional tissues are destroyed mainly through disruption of cell membrane, cellular dehydration, enzyme and protein damage, cell swelling and rupture, thermal shock injury to cells, damage to vasculature, and immune-mediated cytotoxicity. Cryotherapy is used frequently for the treatment of OL lesions with promising results. It can also be used to treat OVH and OVC lesions. Because OVH and OVC lesions are usually fungating and bulky, a combination therapy of shave excision and cryotherapy is needed to achieve a complete regression of the lesion. OSCCs have also been treated by cryotherapy. However, cryotherapy is not the main-stream treatment modality for OSCCs. Cryotherapy seems suitable for treatment of thin or relatively thick plaque-typed lesions such as OL lesions. By careful selection of patients, cryotherapy is a simple, safe, easy, conservative, and acceptable treatment modality for certain benign oral lesions and oral precancers. PMID:24560447

The delivery of proteins has gained momentum with the development of biotechnology sector that provided large-scale availability of therapeutic proteins. The availability is mostly due to the advances in recombinant DNA technology. The low oral bioavailability, however, continues to be a problem for several proteins because of their large molecular size, low permeation through biological membranes, and susceptibility to molecular changes in both biological and physical environments. The demand for effective delivery of proteins by the oral route has brought a tremendous thrust in recent years both in the scope and complexity of drug delivery technology. The important therapeutic proteins and peptides being explored for oral delivery include insulin, calcitonin, interferons, human growth hormone, glucagons, gonadotropin-releasing hormones, enkephalins, vaccines, enzymes, hormone analogs, and enzyme inhibitors. This article reviews the progress in oral delivery of these proteins, provides comments on the strategies to improve their oral bioavailability, and highlights their current market trends.

Full Text Available Fasting is a religious obligation, which can be challenging for individuals with oral conditions due to its stringent code of conduct. Moreover, food abstinence during fasting can restrict oral feeding even further in patients whose nutrition has been already compromised. Previous research has mainly concentrated on oral hygiene and gum health, disregarding orodental conditions and diseases. This highlights the importance of further research in this regard. In this paper, we intended to clarify the correlation between fasting and oral injections, bleeding following tooth extraction, and brushing to overcome common misconceptions which indicate the breach of religious disciplines under such circumstances. We also aimed to determine the grave effects of fasting on health in case of severe immunological deficiencies, chronic oral ulcers and certain drug administration protocols for those with rigid religious beliefs.
Full Text Available Oral malignant melanoma is a rare disease. The common sites of its occurrence are the palate and gingiva with the maxillary arch being affected 80% of the time. Because of their presence at relatively obscure areas in the oral cavity, most of the malignant melanomas of the oral cavity are diagnosed at a late stage. These lesions are associated with poor prognosis. The dental clinician must therefore carefully examine the head, neck, and oral cavity, and any pigmented lesion that may exhibit growth potential must be biopsied. This article describes a case of malignant melanoma that was present in the oral cavity and briefly reviews the relevant literature that explains the nature of this lesion.
We explore the professional value of the collection and analysis of oral histories in the history of radiography. Drawing on oral histories collected from radiographers, we analyse accounts of experiences to identify common themes, some of which are of current significance, whilst others have faded from existence. 15 oral histories were collected from radiographers whose combined practice spans the years 1930-1973. The sample consists of 6 male and 9 female radiographers. Themes identified in the oral histories include radiographers as invisible pioneers who worked in professionally unclaimed territory and their dangerous working environment. The oral histories reveal the working world of the radiographer as having encompassed a practice ethos where challenges became an accepted part of work. We gain insight into less observable aspects of the radiographer's role, the difficulties they faced, how they invented techniques and equipment, and how they managed their practice including protecting the public from ionising radiation sources.

Input multimodality combining speech and hand gestures has motivated numerous usability studies. Contrastingly, issues relating to the design and ergonomic evaluation of multimodal output messages combining speech with visual modalities have not yet been addressed extensively. The experimental study presented here addresses one of these issues. Its aim is to assess the actual efficiency and usability of oral system messages including brief spatial information for helping users to locate objects on crowded displays rapidly. Target presentation mode, scene spatial structure and task difficulty were chosen as independent variables. Two conditions were defined: the visual target presentation mode (VP condition) and the multimodal target presentation mode (MP condition). Each participant carried out two blocks of visual search tasks (120 tasks per block, and one block per condition). Scene target presentation mode, scene structure and task difficulty were found to be significant factors. Multimodal target presenta...

Retrospective and prospective studies were done to evaluate the efficacy of oral cholecystography (OCG) performed before hospital discharge on alcoholic patients with acute pancreatitis. In the retrospective study, OCG adequately opacified the gallbladder in 21 of 26 patients (81%). Of the 5 patients with inadequate opacification, 1 was jaundiced at the time of OCG; the other 4 had OCG before resumption of solid food. In the prospective study, OCG done in nonjaundiced patients shortly after resumption of food yielded adequate opacification in 19 of 21 patients (90%) without gallstones. We conclude that in nonjaundiced alcoholic patients with acute pancreatitis not caused by gallstones, OCG performed after resumption of a solid diet and before hospital discharge is usually successful in opacifying the gallbladder.

Patient: Male, 20 Final Diagnosis: Dermographism Symptoms: Unusual skin reaction to trauma Medication: — Clinical Procedure: — Specialty: Dentistry Objective: Unusual clinical course Background: Dermographism is a type of physical urticaria that can be induced by writing on the skin. It occurs in 2–5% of the population and is considered to be a normal physiological phenomenon. However, in a small subset of patients, it can be symptomatic and may affect the quality of life. The etiology of this disease remains unclear. Case Report: Herein, we present a case of dermographism in a 20-year-old male and discuss the involvement of the oral mucosa in this condition. Conclusions: Although this condition is well known to occur in the skin, we believe this condition is rarely discussed among dentists. All healthcare providers, especially dentists, should know its potential to cause complications during dental procedures. PMID:27324161

Consumers frequently encounter moral violations in everyday life. They watch movies and television shows about crime and deception, hear news reports of corporate fraud and tax evasion, and hear gossip about cheaters and thieves. How does exposure to moral violations influence consumption? Because moral violations arouse disgust and because disgust is an evolutionarily important signal of contamination that should provoke a multi-modal response, we hypothesize that moral violations affect a key behavioral response to disgust: reduced oral consumption. In three experiments, compared with those in control conditions, people drank less water and chocolate milk while (a) watching a film portraying the moral violations of incest, (b) writing about moral violations of cheating or theft, and (c) listening to a report about fraud and manipulation. These findings imply that "moral disgust" influences consumption in ways similar to core disgust, and thus provide evidence for the associations between moral violations, emotions, and consumer behavior.

The mortality of oral cancer (OC) has shown only moderate improvement over recent decades. Treatment of OC remains mainly surgical with increasing contributions from radio- and chemotherapy. Early diagnosis and adequate management improves patient prognosis whilst lymphatic spread worsens the prognosis significantly. Copious extirpation of the tumour achieving tumour-free margins, as well as the effective removal of affected or suspect lymph nodes are vital steps to ensure long-term survival. Reconstructive ablities have improved to such an extent that many patients can be fully integrated in society after treatment. New modalities such as intensity modulated radiation therapy (IMRT) or volumetric modulated arc therapy (VMAT) ensures selective radiation and significantly contributes to improved quality of life. Photodynamic therapy and other targeted therapy options will play an increasingly important role in the future. PMID:23957099
Eighty five patients of oral cavity cancer, treated with radiation at the Department of Therapeutic Radiology, Korea Cancer Center Hospital, during the period from March 1985 to September 1990 were analyzed retrospectively. Among 85 patients, 37 patients were treated with radiation only and 48 patients were treated with radiation following surgery And 70 patients received external irradiation only by 60Co with or without electron, the others were 7 patients for external irradiation plus interstitial implantation and 8 patients for external irradiation plus oral cone electron therapy. Primary sites were mobile tongue for 40 patients, mouth floor for 17 patients, palate for 12 patients, gingiva including retromolar trigone for 10 patients, buccal mucosa for 5 patients, and lip for 1 patient. According to pathologic classification, squamous cell carcinoma was the most common (77 patients). According to AJC TNM stage, stage I + II were 28 patients and stage III + IV were 57 patients. Acturial overall survival rate at 3 years was 43.9%, 3 year survival rates were 60.9% for stage I + II, and 23.1% for stage III + IV, respectively. As a prognostic factor, primary T stage was a significant factor (p<0.01). The others, age, location, lymph node metastasis, surgery, radiation dose, and cell differentiation were not statistically significant. Among those factors, radiation plus surgery was more effective than radiation only in T3 + T4 or in any N stage although it was not statistically sufficient(p<0.1). From those results, it was conclusive that definitive radiotherapy was more effective than surgery especially in the view of pertaining of anatomical integrity and function in early stage, and radiation plus surgery was considered to be better therapeutic tool in advanced stage

Full Text Available The aim of this paper is to make known the potential of fluoridated salt in community oral health programs, particularly in South Eastern Europe. Since 1922, the addition of iodine to salt has been successful in Switzerland. Goiter is virtually extinct. By 1945, the cariesprotective effect of fluorides was well established. Based on the success of water fluoridation, a gynecologist started adding of fluoride to salt. The sale of fluoridated salt began in 1956 in the Swiss Canton of Zurich, and several other cantons followed suit. Studies initiated in the early seventies showed that fluoride, when added to salt, inhibits dental caries. The addition of fluoride to salt for human consumption was officially authorized in 1980-82. In Switzerland 85% of domestic salt consumed is fluoridated and 67% in Germany. Salt fluoridation schemes are reaching more than one hundred million in Mexico, Colombia, Peru and Cuba. The cost of salt fluoridation is very low, within 0.02 and 0.05 € per year and capita. Children and adults of the low socio-economic strata tend to have substantially more untreated caries than higher strata. Salt fluoridation is by far the cheapest method for improving oral health. Conclusions. Salt fluoridation has cariostatic potential like water fluoridation (caries reductions up to 50%. In Europe, meaningful percentages of users have been attained only in Germany (67% and Switzerland (85%. In Latin America, there are more than 100 million users, and several countries have arrived at coverage of 90 to 99%. Salt fluoridation is by far the cheapest method of caries prevention, and billions of people throughout the world could benefit from this method.

The incidence of inflammatory bowel diseases (IBD) - Crohn's disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

Full Text Available Oral tolerance is classically defined as the suppression of immune responses to antigens (Ag that have been administered previously by the oral route. Multiple mechanisms of tolerance are induced by oral Ag. Low doses favor active suppression, whereas higher doses favor clonal anergy/deletion. Oral Ag induces Th2 (IL-4/IL-10 and Th3 (TGF-β regulatory T cells (Tregs plus CD4+CD25+ regulatory cells and LAP+T cells. Induction of oral tolerance is enhanced by IL-4, IL-10, anti-IL-12, TGF-β, cholera toxin B subunit (CTB, Flt-3 ligand, anti-CD40 ligand and continuous feeding of Ag. In addition to oral tolerance, nasal tolerance has also been shown to be effective in suppressing inflammatory conditions with the advantage of a lower dose requirement. Oral and nasal tolerance suppress several animal models of autoimmune diseases including experimental allergic encephalomyelitis (EAE, uveitis, thyroiditis, myasthenia, arthritis and diabetes in the nonobese diabetic (NOD mouse, plus non-autoimmune diseases such as asthma, atherosclerosis, colitis and stroke. Oral tolerance has been tested in human autoimmune diseases including MS, arthritis, uveitis and diabetes and in allergy, contact sensitivity to DNCB, nickel allergy. Positive results have been observed in phase II trials and new trials for arthritis, MS and diabetes are underway. Mucosal tolerance is an attractive approach for treatment of autoimmune and inflammatory diseases because of lack of toxicity, ease of administration over time and Ag-specific mechanism of action. The successful application of oral tolerance for the treatment of human diseases will depend on dose, developing immune markers to assess immunologic effects, route (nasal versus oral, formulation, mucosal adjuvants, combination therapy and early therapy.

Full Text Available Objectives: The aims of the study were to assess current practice in oral health care among residential homes for the elderly in Manchester, Salford and Stockport and to evaluate the effectiveness of a programme to increase carers’ knowledge in key areas. Methods: The study was part of a randomised control trial, conducted in 56 residential homes, allocated randomly to test and control groups matched using the minimisation method. Managers of participating homes were interviewed to gather baseline data on the homes and oral care provided. A training session in oral health care for the elderly was provided for care staff in the homes. Carers` knowledge was assessed before and after the training session and their perceptions of the training were sought. Results: The survey of mangers revealed common inadequacies: the lack of any training for care staff in oral care; the lack of protocols for oral care (at 68% of homes; the lack of initial oral assessment. After the training session, the oral health knowledge of carers (467 carers showed a significant improvement (McNemar Test, P< 0.005. Conclusion: Current practice in most homes is inadequate. The training sessions improved the carers’ knowledge in key areas but improvements in the organisation and delivery of care are clearly also required.

This study aimed to evaluate objectively and subjectively the oral health of elders with Parkinson's disease (PD), using clinical oral assessments and the General Oral Health Assessment Index (GOHAI). Subjects included 37 removable prosthesis wearers, 17 with PD (mean age 69.59±5.09 years) and 20 without PD (mean age 72.00±5.69 years). The objective assessment included an evaluation of oral characteristics, including the number of remaining teeth, decayed, missing and filled teeth (DMFT), visible plaque index (VPI), salivary flow rate and removable prosthesis conditions. The subjective assessment included self-perception of oral health collected using the GOHAI index. The number of remaining teeth, DMFT, VPI, salivary flow rate and GOHAI data were compared between the groups using t-tests. Removable prosthesis conditions were analyzed using χ2 tests (p0.05). Greater maxillary prosthesis defects were observed in the control group (p=0.037). GOHAI scores were low for the PD group and moderate for controls, yielding a group difference (p=0.04). In conclusion, elders with PD have similar oral health to controls. Although all elders had few remaining teeth, high DMFT and high VPI, PD elders had more negative self-perceptions of their oral health than did the controls. PMID:27224571

Oral cavity and oropharyngeal cancer (oral cancer) is a deadly disease that is increasing in incidence. Worldwide 5-year survival is only 50% due to delayed intervention with more than half of the diagnoses at stage III and IV, whereas earlier detection (stage I and II) yields survival rates up to 80% to 90%. Salivary soluble CD44 (CD44), a tumor-initiating marker, and total protein levels may facilitate oral cancer risk assessment and early intervention. This study used a hospital-based design with 150 cases and 150 frequency-matched controls to determine whether CD44 and total protein levels in oral rinses were associated with oral cancer independent of age, gender, race, ethnicity, tobacco and alcohol use, and socioeconomic status (SES). High-risk subjects receiving oral cancer prevention interventions as part of a community-based program (n = 150) were followed over 1 year to determine marker specificity and variation. CD44 ≥5.33 ng/mL was highly associated with case status [adjusted OR 14.489; 95% confidence interval (CI), 5.973-35.145; P cancer. In contrast, specificity in the high-risk community was 74% and reached 95% after annual retesting. Simple and inexpensive salivary CD44 and total protein measurements may help identify individuals at heightened risk for oral cancer from the millions who partake in risky behaviors.

Full Text Available Myiasis is a rare disease primarily caused by the invasion of tissue by larvae of certain dipteran flies. Oral myiasis is still more "rare" and "unique" owing to the fact that oral cavity rarely provides the necessary habitat conducive for a larval lifecycle. Common predisposing factors are poor oral hygiene, halitosis, trauma, senility, learning disabilities, physically and mentally challenged conditions. Oral myiasis can lead to rapid tissue destruction and disfigurement and requires immediate treatment. Treatment consists of manual removal of maggots from the oral cavity after application of chemical agents. Good sanitation, personal and environmental hygiene and cleanliness and special care for debilitated persons are the best methods to prevent oral myiasis. This case report describes the presentation of oral myiasis caused by musca nebulo (common house fly in a 40-year-old male patient, with recent maxillofacial trauma. The patient was treated by manual removal larvae by topical application of turpentine oil, followed by surgical debridement of the wound and open reduction and internal fixation of the fracture.
As the public's oral health care needs increase in complexity, there is renewed attention to the ethical dimensions of community oral health decision making and the development of public health ethics in teaching and research in dentistry. Despite their reduction globally, oral diseases persist with a particular distribution pattern that is a reflection of the increasingly widespread inequality in access to community oral health preventive and dental care. This is due to differences in the appropriateness, availability, accessibility, and acceptability of oral health education and the care provided. This article provides an overview of community oral health from an ethical perspective, including the importance of equity, human rights, and social justice in providing oral health care to the underserved. The need for a paradigm shift from highly technical and individualistic dental training curricula is discussed, together with the need to instill a holistic approach to ethical and social responsibility in new dental graduates. It concludes with some possible strategies, using the overarching principles of ethics and bioethics that are applicable to practice among vulnerable populations. PMID:25941240

Voriconazole (VRCZ), a broad-spectrum triazole, is served in two dosage forms-injection and oral. VRCZ is difference dosage of oral and intravenous administration writing a medical package insert in Japan. 6 mg/kg intravenous injection (IV) twice daily for first day as initial loading dose, followed by 3-4 mg/kg IV twice daily between meals is recommended. 300 mg orally twice daily for first day as initial loading dose, followed by 150-200 mg orally twice daily between meals is recommended. Patients weighing over 40 kg, 200 mg orally twice daily between meals is recommended. Patients weighing under 40 kg, 100 mg orally twice daily between meals is recommended, increase to 150 mg twice daily if inadequate response. This study evaluated VRCZ trough concentration and oral dosage in the 23 cases which administered VRCZ to analysis for TDM in Aichi University Hospital. Spearman rank correlation coefficient was calculated to examine relationships among variables. The level of statistical significance was set at p=0.05. All data were analyzed and processed on JMP 8 (SAS Institute Japan). There was a significant positive correlation between VRCZ trough concentration and dose/weight (r=0.47 poral dosage is appropriate to administer dose/weight (mg/kg) twice a day as same as IV.

Full Text Available Objectives: The study aims to establish an etiological association between diabetes and precancerous lesions of the oral cavity by cytomorphometric analysis of the oral epithelium. Study Design: Smears were obtained from three distinct oral sites - buccal mucosa, dorsum of the tongue and the floor of the mouth in ten controls and ten patients previously diagnosed with type II diabetes. The oral smears were stained with Papanicolaou SA-36 solution. An eye - piece graticule was used to obtain the cytoplasm and nuclear dimension; where larger dimension was denoted as "D" and the smaller dimension was denoted as "d". The nuclear area (NA, nuclear diameter (ND, cytoplasmic area (CA and the cytoplasmic / nuclear ratio (C/N were evaluated from 50 cells predominant in each oral site. Statistical Analysis: The cytomorphometric data obtained was compared between the group of diabetic patients and the control groups using the student′s t- test (SPSS version 11.0. Results: Results showed that the nuclear area and the nuclear diameter of oral epithelial cells were increased in diabetic patients, as compared to non- diabetics, while the non- diabetic patients demonstrated an increase in nuclear ratio. Conclusions: The results from this study suggest that diabetes mellitus can cause alterations in oral epithelial cells that are detectable with exfoliative cytology.

Oral cancer is historically linked to well-known behavioural risk factors such as tobacco smoking and alcohol consumption. Other risk factors include age over 40, male sex, several dietary factors, nutritional deficiencies, viruses, sexually transmitted infections, human papillomavirus, chronic irritation, and possibly genetic predisposition. Precancerous lesions in the oral cavity include leukoplakia, erythroplakia, and lichen planus. Histology of oral cancer varies widely but the great majority are squamous cell carcinomas.Epidemiological studies and cancer registries have shown a consistently increased risk of oral malignancies in kidney, bone marrow, heart, or liver transplantation, in graft vs host disease, and in patients with HIV infection. Because of the increasing use of immunosuppressive drugs in patients with inflammatory bowel disease, it is useful to more accurately delineate the consequences of chronic immunosuppression to the oral cavity. Oral cancer and precancerous oral lesions in patients with inflammatory bowel disease [IBD] have been scarcely reported and reviews on the topic are lacking.We conducted a literature search using the terms and variants of all cancerous and precancerous oral manifestations of inflammatory bowel diseases. By retrieving the existing literature, it is evident that patients with IBD belong to the high-risk group of developing these lesions, a phenomenon amplified by the increasing HPV prevalence. Education on modifiable risk behaviours in patients with oral cancer is the cornerstone of prevention.Oral screening should be performed for all IBD patients, especially those who are about to start an immunosuppressant or biological drug.

Full Text Available Introduction. It has been suggested that asthmatic patients may have a higher risk for oral diseases, both as a result of the medical condition and effects of medications. Objective. The aim of the study was to determine the oral health status of children with asthma and to evaluate the oral health parameters according to the medications and severity of the disease. Methods. The study group consisted of 158 children with asthma and 100 healthy control subjects aged 2-18 years. The diagnosis of dental caries was performed using the Decayed, Missing, and Filled Teeth (DMFT/dmft criteria. The oral hygiene, periodontal status and gingival health were assessed with the Simplified Oral Hygiene Index (Greene-Vermillion, Community Periodontal Index of Treatment Needs and Gingival Index (Löe-Silness, respectively. Results. Thirty (19% patients with asthma and 43 (43% healthy children were caries-free (p<0.001. There were no significant differences between asthmatic and control children in caries experience (for children with asthma mean DMFT=2.1±1.8, mean dmft=4.2±3.3; for healthy children mean DMFT=2.5±0.9, mean dmft=5.2±1.3. Level of asthma control did not have influence on dental health, while dose of inhaled corticosteroid had impact on primary dentition. Periodontal status and gingival health did not differ between asthmatic and control children. However, children with asthma had poorer oral hygiene (p<0.001. Conclusion. Results of the study do not show a relationship between asthma and oral diseases. However, further improvement could be made in educating children and parents on the importance of good oral hygiene and prevention of oral diseases.
Cancer is a major public health problem in the United States and many other parts of the world. One in 4 deaths in the United States is due to cancer. Oral cancer (OC) is the sixth most common cancer worldwide. Oral cancer can be divided into three clinic-pathological categories: carcinoma of the lip vermillion, carcinoma of the oral cavity proper, and carcinoma of the oropharynx. The chief predisposing factors are tobacco use, alcohol consumption, and persistent viral infections such as HPV ...

Full Text Available Oral allergy syndrome (OAS is an allergic reaction in the oral cavity subsequent to the consumption of food such as fruits, nuts, and vegetables. It occurs mainly due to homology of proteins of pollen to the proteins of fruits and vegetables. In OAS, the immune system produces antibodies that are directed against the proteins of pollen and structurally similar proteins in food, hence, resulting in allergic symptoms limited mainly to the oral cavity. In this review, we have summarized the etiopathogenesis, clinical features, diagnosis, and management of OAS as an update for stomatologists.

Full Text Available We report an unusual case of a glial heterotopia arising from the oral cavity of an African neonate. The patient presented with an external pedunculated oral mass which was connected to the anterior hard palate by a firm, rubbery stalk of mucosal tissue. While the mass appeared painless, it interfered with the infant's feeding and was disturbing to the parents. After a computed tomography scan excluded an intracranial connection, the mass was excised at its base and sent for biopsy. Histopathology examination confirmed glial heterotopia. Glial heterotopias should be included in the differential diagnosis of congenital masses in the oral region.

The oral cavity is an area of the human body that is often given only cursory surveillance by primary care physicians. In this article, I have discussed a comprehensive approach for collecting subjective and objective data from the patient that is pertinent to oral conditions. Most common and critical problems have been reviewed in detail, focusing on their definition, epidemiology, pathophysiology, clinical manifestations, diagnosis, and management. This review is intended to sensitize physicians to the need to evaluate oral complaints more completely, to diagnose them more accurately, and to treat them more successfully. PMID:2196616

Introduction The management of oral mucositis is a challenge, due to its complex biological nature. Over the last 10 years, different strategies have been developed for the management of oral mucositis caused by chemotherapy in cancer patients. Material and Methods An exhaustive search was made of the PubMed-Medline, Cochrane Library and Scopus databases, crossing the key words “oral mucositis”, “prevention” and “treatment” with the terms “chemotherapy” and “radiotherapy” by means of the bool...
Oral mucositis is a complication of head and neck radiotherapy. It is understood what causes the inflammation and what biological tissue changes occur, however, a definite cure for oral mucositis has not yet been found. Supportive treatments, analgesics, antimicrobials and anti-inflammatory agents have been prescribed, none of which has been a thorough measure of treatment. An effective cure for oral mucositis is still in the midst of scientific research. In the interim local palliative treatments will help to alleviate the patients', debilitating symptoms

The first part of this chapter describes the unique characteristics of the mouth with special emphasis on the oral microbiota. Next, the highly prevalent dental diseases are briefly described together with more rare but still important diseases and symptoms of the mouth. Prevention and treatment of oral and dental diseases are also discussed focusing on aspects considered important with respect to the potential application of prebiotics and probiotics. The second part of the chapter then concentrates on research data on prebiotics and probiotics in the oral health perspective, ending up with conclusions and visions for future research.

More than 300 000 new cases worldwide are being diagnosed with oral cancer annually. Complexity of oral cancer renders designing drug targets very difficult. We analyse protein-protein interaction network for the normal and oral cancer tissue and detect crucial changes in the structural properties of the networks in terms of the interactions of the hub proteins and the degree-degree correlations. Further analysis of the spectra of both the networks, while exhibiting universal statistical behaviour, manifest distinction in terms of the zero degeneracy, providing insight to the complexity of the underlying system.

Cryotherapy is the deliberate destruction of tissue by application of extreme cold. It is well received by patients due to a relative lack of discomfort, the absence of bleeding and minimal to no scarring after healing. It has many applications in oral medicine and clinical oral pathology, and is extremely usefu in patients for whom surgery is contra-indicated due to either age or medical history. In this paper we outline the principles, mechanisms of action, and current applications of cryotherapy in the treatment of oral lesions, and present some clinical cases. PMID:16669469

Athletes use intravenous (IV) saline in an attempt to maximize rehydration. The diuresis from IV rehydration may be circumvented through the concomitant use of oral glycerol. We examined the effects of rehydrating with differing regimes of oral and IV fluid, with or without oral glycerol, on hydration, urine, and endocrine indices. Nine endurance-trained men were dehydrated by 4% bodyweight, then rehydrated with 150% of the fluid lost via four protocols: (a) oral = oral fluid only; (b) oral glycerol = oral fluid with added glycerol (1.5 g/kg); (c) IV = 50% IV fluid, 50% oral fluid; and (d) IV with oral glycerol = 50% IV fluid, 50% oral fluid with added glycerol (1.5 g/kg), using a randomized, crossover design. They then completed a cycling performance test. Plasma volume restoration was highest in IV with oral glycerol > IV > oral glycerol > oral. Urine volume was reduced in both IV trials compared with oral. IV and IV with oral glycerol resulted in lower aldosterone levels during rehydration and performance, and lower cortisol levels during rehydration. IV with oral glycerol resulted in the greatest fluid retention. In summary, the IV conditions resulted in greater fluid retention compared with oral and lower levels of fluid regulatory and stress hormones compared with both oral conditions. PMID:25943662
To date, nine case-control studies conducted in developed countries have identified an association between oral contraceptives (OCs) and liver cancer. The most recent population-based data from both developed and developing countries failed to confirm such an association, however. A study conducted by the World Health Organization in eight developing countries (Chile, China, Colombia, Israel, Kenya, Nigeria, Philippines, and Thailand), in which 122 women with liver cancer were matched with 802 controls, found no elevated risk for OC users compared with never-users (relative risk, 0.7; 95% confidence interval, 0.4-1.2). This study is particularly significant since it was conducted in countries where hepatitis B virus infection, an important risk factor for primary liver cancer, is widespread. In addition, population mortality data from the US, UK, Japan, and Sweden have failed to document increases in liver cancer cases coincident with increases in OC use. Given that population statistics can detect changes on the magnitude of a 40-50% decrease in the risk of ovarian and endometrial cancer related to OC use, they should be able to detect increases of two to 20 times the risk of liver cancer. The increased risk of liver cancer found in the case-control studies may reflect bias resulting from the small size of these studies. PMID:12348250
Full Text Available In 1950, 520 newborn to adult patients with diarrhea and vomiting were hospitalized in Tehran and some of the southern cities of Iran. The patients were different in: States of nutrition, severity of fluid deficits and a wide range of electrolyte abnormalities. They were treated in two separate phases using 2 different solutions, which are formulated upon physiobiochemical principles being iso-osmatic with plasma. For deficit therapy solution no. 1 (Sodium 80, potassium 20 mmol/l was administrated orally at a rate of 40 ml/kg. Per hour until all signs of dehydration disappeared. (This is maintenance therapy the second solution (Potassium 30, sodium 40 mmol/l, i.e. K:Na in normal=75% was given sip by sip at a rate of 250 ml/kg/24 hours until diarrhea stopped. Intravenous fluids were not used at all even in severe dehydration and shock. The efficacy and safety of this regimen were confirmed by rapid and successful dehydration and correction of a wide range of electrolyte abnormalities present on admission.
Squamous cell carcinomas of the oral cavity are curable. When early tumor (T1 and T2) is diagnosed and treated, cure rates by surgery or irradiation are high. The choice of therapeutic modalities for these lesions is complex and depends on the site of origin and size of the tumor, the presence or absence of nodal metastases, and the age, physical, medical, and socioeconomic status of the patient. Other factors include the willingness of the patient to return for a protracted course of radiation therapy, the skill of the physician, and the relative morbidity and cosmesis of the two forms of treatment. In general, surgery may be considered for early (T1) lesions if the deformity resulting from surgery is minimal. If resection involves major morbidity, such as a deformity that alters cosmesis or the function of the speech and swallowing mechanisms, then radiation therapy is preferred. For medium-sized (T2) tumors, superficial radiation therapy is the treatment of choice, for it controls the disease and preserves normal function and anatomy. Surgery is reserved for radiation failures. Extensive disease (T3 and T4) often associated with bone and muscle involvement and cervical lymph node metastases is rarely curable by radiation therapy or surgery alone; a combined approach using radiation therapy and surgery is therefore the procedure of choice
Oral allergy syndrome (OAS) is an allergic reaction that occurs after consumption of fresh fruits and vegetables in patients with allergy to pollen. It is mediated by immunoglobulin E (IgE) antibodies and symptoms arise as a result of cross-reactivity between pollen and plant-derived food. OAS is rarely seen in young children, but the prevalence increases with age. The objectives of the study were to identify the prevalence of OAS and probable risk factors in children and adolescents with seasonal allergic rhinitis (AR). One-hundred and twenty patients with seasonal AR were included. Patients were diagnosed based on their clinical history, skin prick test outcome and specific IgE. In patients describing OAS, prick-by-prick tests with fresh fruit or vegetables were carried out. Thirty-two patients had OAS and it was more frequent in female patients than in male patients. OAS was more frequent in adolescents than in small children and in patients with higher total IgE. OAS was significantly more prevalent in patients with AR and asthma (P=0.0016), as was the case in patients with AR and atopic dermatitis (P=0.0004). OAS is rarely diagnosed in small children, partly because of an inadequate clinical history. Patients with OAS may have some risk factors in addition to pollen allergy, and those with more severe atopy are more likely to develop OAS. PMID:25819922
A number of acute oral complications may be associated with cancer therapy in children, but the extent and duration of these complications, and the most effective management techniques. have not been well described. The few studies differ in design, making comparisons difficult. Well-controlled, prospective clinical studies are needed to define the most effective strategies for the management of acute oral complications in children. However, it is clear that dental intervention prior to cancer therapy is an important factor in the optimal preparation of the patient. During cancer therapy, intensive supervised oral preventive protocols appear to be of benefit to the child's oral health, overall comfort, and well-being. Furthermore, the prevention of oral infection may significantly reduce the morbidity associated with cancer therapy. Long-term preventive oral care may help prevent dental disease and infection in medically compromised children and contribute to improving the quality of life. 41 references

Multiple sclerosis is a complex neurological condition affecting sensory and motor nerve transmission. Its progression and symptoms are unpredictable and vary from person to person as well as over time. Symptoms of orofacial pain, trigeminal neuralgia, spasticity, spasms, tremor, fatigue, depression and progressive disability, impact on the individual's ability to maintain oral health, cope with dental treatment and access dental services. Also, many of the medications used in the symptomatic management of the condition have the potential to cause dry mouth and associated oral disease. There is no cure for multiple sclerosis, and treatment focuses on prevention of disability and maintenance of quality of life. The oral health care team plays an essential role in ensuring that oral health impacts positively on general health. This review highlights the epidemiology, etiology, pathophysiology, diagnosis, oral and craniofacial manifestations and their management, and oral health care considerations in patients with MS.

According to theory, health beliefs are related to health behaviors. We investigated whether individuals who hold favorable oral-health-related beliefs over time have better adult oral health than those who do not. Beliefs about the efficacy of water fluoridation, keeping the mouth clean, avoiding sweet foods, visiting the dentist, using dental floss, and using fluoridated toothpaste were assessed in a birth cohort at ages 15, 18, and 26 years. At each age, the majority of participants endorsed the importance of each practice. However, there was also evidence of instability across time. Individuals who held stable favorable dental beliefs from adolescence through adulthood had fewer teeth missing due to caries, less periodontal disease, better oral hygiene, better self-rated oral health, and more restorations. Dental beliefs can change between adolescence and young adulthood, and these changes are related to oral health. In particular, unfavorable dental health beliefs are related to poorer oral health.

Histoplasmosis is an endemic mycoses caused by Histoplasma capsulatum with endemicity around midwestern United States and central America. The endemicity of histoplasmosis in India is not clearly known. Histoplasmosis, especially oral histoplasmosis, is now increasingly being reported from India. We report here a culture-confirmed and sequence confirmed, oral histoplasmosis in a HIV seropositive individual who was referred to our regional cancer centre with a suspicion of oral cancer.
Intra-oral electron therapy for carcinoma of the oral cavity is a well-established treatment modality. However, the conventional metallic tubes were inconvenient to use because the irradiation field had to be confirmed by a side mirror. We devised transparent acrylic tubes which enable the positioning easy by confirming the tumor and irradiation field directry. Seven cases of various intra-oral carcinomas were treated with these new transparent acrylic tubes and good results were obtained. (author)

Full Text Available Over-the-counter products rarely cause unwanted reactions in the oral cavity. Oral reactions to these agents are not specific and might present with various clinical oral findings. Detailed medical history is a key to the proper diagnosis of these lesions and fortunately other diagnostic procedures are rarely needed. Lesions are usually managed with elimination of the offending agent and with topical steroids. In more severe cases systemic steroids should be applied.

Full Text Available Oral cancer is the largest group of cancer that categorizes into the head and neck region and worldwide health problem. Exact cause of oral cancer is unknown. Risk factors for cancer could be varied including Iron deficiency anemi a, are alcohol, tobacco, immunologic susceptibility, gene mutations, epithelial cell growth, suppressor proteins and disease of chemotherapy, such as in cases of lymphoma and leukemia. Role of viruses have also been reported in the etiology. Dietary factor s such as high fat and low fiber may play a role in carcinogenesis in some sites. High incidence of alcoholism is relevant because alcohol intake has been related to an increase risk of developing oral cancer. Other signaling factors have also been propose d to have a role. The paper presents a review on oral cancer, its causes & concern.

Failures of oral contraceptives are possible when combined with rifampicin or antiepileptics, especially phenobarbitone and phenytoin. The mode of action is shown by clinical trials to be due to induction of hepatic enzymes thus increasing the steroid metabolism. Failure or oral contraceptives has occurred with the concomitant use of antibiotics, i.e. ampicillin and sulfonamides. Clinical trials have focused upon the changes in the intestinal flora induced by antibiotics. This might influence the enterohepatic circulation of estrogen and thereby decrease reabsorption of estrogen, but this has not been definitely proved. The failures may be caused by individual pharmacokinetics of oral contraceptives. Oral contraceptives are able to influence the pharmacodynamics of various other drugs metabolized by oxidation or conjugation but besides an increased pharmacological effect of prednisolone and increased toxicity of imipramine the clinical importance is uncertain.

Considerable human illness can be linked to the development of oral microbiota disequilibria. The predominant oral cavity commensal, Streptococcus salivarius has emerged as an important source of safe and efficacious probiotics, capable of fostering more balanced, health-associated oral microbiota. Strain K12, the prototype S. salivarius probiotic, originally introduced to counter Streptococcus pyogenes infections, now has an expanded repertoire of health-promoting applications. K12 and several more recently proposed S. salivarius probiotics are now being applied to control diverse bacterial consortia infections including otitis media, halitosis and dental caries. Other potential applications include upregulation of immunological defenses against respiratory viral infections and treatment of oral candidosis. An overview of the key steps required for probiotic development is also presented. PMID:23231486

The poor physical health faced by people with mental illness has been the subject of growing attention, but there has been less focus on the issue of oral health even though it is an important part of physical health. This article discusses the two-way association between oral and mental health. In one direction, the prospect of dental treatment can lead to anxiety and phobia. In the other, many psychiatric disorders, such as severe mental illness, affective disorders, and eating disorders, are associated with dental disease: These include erosion, caries, and periodontitis. Left untreated, dental diseases can lead to teeth loss such that people with severe mental illness have 2.7 times the likelihood of losing all their teeth, compared with the general population. Possible interventions include oral health assessments using standard checklists that can be completed by nondental personnel, help with oral hygiene, management of iatrogenic dry mouth, and early dental referral.

Full Text Available Inhalation therapy has been employed as the mainstay of the treatment in chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD. Beta-2 agonists, anticholinergic bronchodilators, inhaled corticosteroids, and sodium cromoglycate are often used alone or in combination in an inhaled form. Studies have shown that inhaled drugs used in the treatment have some adverse effects on the oral health based on their dosage, frequency, and duration of use. Several oral conditions such as xerostomia, dental caries, candidiasis, ulceration, gingivitis, periodontitis, and taste changes have been associated with inhalation therapy. Since the prevalence of chronic respiratory diseases is rising, it is important to provide optimal oral care to the individuals receiving inhalation therapy. This article will review the influence of inhaled drugs on the oral health of individuals and adequate management and prevention of the same.

Few studies have examined, comprehensively and prospectively, determinants of oral-health-related quality of life. The aim of this study was to examine the relationships between psychosocial factors and oral health status, health perceptions, and quality of life. Measures of symptom and functional status, health perceptions, quality of life, oral health beliefs, and psychological (sense of coherence, self-esteem, health locus of control) and social factors (parents' income and education) were collected from 439 12- and 13-year-olds at baseline and six-month follow-up, together with a clinical examination at baseline. Structural equation modeling indicated that increased levels of caries and more symptoms predicted more functional limitations, and, cross-sectionally, greater functional impact was associated with worse health perceptions, which were linked to lower quality of life. Sense of coherence was the most important psychosocial predictor. These factors are important in understanding how oral health affects young people's daily lives. PMID:20739689

Oral History er en forskningsmetode, der indsamler, dokumenterer og fortolker vidnesbyrd og erindringer gennem mundtlige interviews. Oral History har som metode vist sig særligt egnet til at udforske historiske processer, fx sociale og erindringshistoriske forandringer, ligesom den kan påvise...... forbindelsen mellem individuelle erfaringer og kulturelle og sociale sammenhænge. Mens Oral History internationalt er i vældig fremgang, har historievidenskaben i Danmark længe fastholdt en skepsis overfor den mundtlige beretning. Først med nyere strømninger indenfor faget har det mundtlige vidnesbyrd opnået...... et gennembrud, der lover godt for den metodiske udvikling og inspirerer til øget brug af mundtlige kilder i såvel forskning som undervisning. Oral History i Danmark er den første bog på dansk om danske historikeres erfaringer med det mundtlige interview og introducerer til både arkivarisk...

The oral bioavailability of zinc was studied in nonpregnant adults before and 24 hours after two weeks of oral supplementation with iron and folic acid. Bioavailability was greatly reduced, and the shape of the plasma curves suggested that this was due to impairment of the intestinal absorption of zinc. The findings suggest that the reduced bioavailability of zinc occurs because of interelement competition in the bowel wall. This might induce zinc depletion.

We report an unusual case of a glial heterotopia arising from the oral cavity of an African neonate. The patient presented with an external pedunculated oral mass which was connected to the anterior hard palate by a firm, rubbery stalk of mucosal tissue. While the mass appeared painless, it interfered with the infant's feeding and was disturbing to the parents. After a computed tomography scan excluded an intracranial connection, the mass was excised at its base and sent for biopsy. Histopath...
Full Text Available Amelanotic melanoma is a variant of malignant melanoma comprising 2% to 8% of all malignant melanomas. The amelanotic presentation of melanoma in the oral cavity is extremely rare and has been reported only occasionally in the literature. Moreover, the lack of melanin makes these tumors difficult to diagnose than that of pigmented lesions and the prognosis tends to be poorer. Herein, we report an amelanotic melanoma involving the oral mucosa of the maxilla in a 27 year-old male.

The contraceptive and non contraceptive advantages of oral chormonal contraceptives as well as the good control on fertility, make it one of the most preffered method of contraception. The normal vaginal flora is a dynamic ecosystem and itsequilibrium and status of eubyosis amongst its inhabitants is an important mechanism against exogenous infections. The use of oral contraceptives is not associated with significant changes in the vaginal microbial flora; the normal concentration of the lactobacillli is preserved. PMID:16889189

Hypocalcemia in dairy cattle around parturition can be manifest as clinical milk fever or subclinical hypocalcemia. Subclinical hypocalcemia has the greatest economic effect because it affects a much higher proportion of cows. Oral calcium supplements are used to mitigate the effects of both forms of hypocalcemia. Oral calcium supplements are appropriate for cows displaying early clinical signs of hypocalcemia and prophylactically to lessen the negative impacts of hypocalcemia. PMID:23809900

In a male patient with rhinocerebral invasive aspergillosis, prolonged high-dosage oral administration of voriconazole led to hepatotoxicity combined with a severe cutaneous reaction while intravenous administration in the same patient did not. High concentrations in the portal blood precipitate liver enzyme abnormalities, and therefore, oral administration of voriconazole may have a hepatotoxicity profile different from that of intravenous (i.v.) administration. Intravenously administered vo...

As our knowledge of host-microbial interactions within the oral cavity increases, future treatments are likely to be more targeted. For example, efforts to target a single species or key virulence factors that they produce, while maintaining the natural balance of the resident oral microbiota that acts to modulate the host immune response would be an advantage. Targeted approaches may be directed at the black-pigmented anaerobes, Porphyromonas gingivalis and Prevotella intermedia, associated ...
