Clinical evaluation of oral lesions associated with dermatologic diseases / Avaliação clínica de lesões bucais associadas a doenças dermatológicas

Dermatologic diseases are not only represented by lesions affecting the skin but also by manifestations that may involve the mucous membranes, including oral mucosa. Objectives: To assess the frequency of oral manifestations associated with dermatologic diseases considering the location and clinical characteristics of the lesions found and also gender and age of the patients. Materials and Methods: It was an observational, cross-sectional study of patients who sought for treatment in the Dermatology Department of M. M. College of Medical Sciences & Research, Haryana (n=88). Results: The age of the patients varied from 5 to 88 and there was predominance of female patients. Of the cases studied, 35% were diagnosed as lichen planus, 11% as lupus erythematosus, 13% as erythema multiforme, 30% as pemphigus vulgaris and 11% as of pemphigoid group. Oral manifestations were more common among patients suffering from lichen planus (51%) and pemphigus vulgaris (23%). The most common clinical presentation found was reticular lichen planus located most predominantly in the buccal mucosa. Conclusions: It is essential for the dentists to know these pathologies so that they should be able to diagnose them at an early stage of the disease and direct the patients to get adequate treatment. Furthermore, intra-oral examination should be included as a routine practice in dermatological services...

As doenças dermatológicas não estão representadas apenas pelas lesões que afetam a pele, mas também por manifestações que podem envolver as mucosas, incluindo a mucosa oral. Objetivos: avaliar a frequência de manifestações orais associadas a doenças dermatológicas, considerando localização e características clínicas das lesões encontradas, além do sexo e da idade dos pacientes. Materiais e Métodos: Estudo observacional transversal de pacientes que procuraram atendimento no serviço de dermatologia da Faculdade de Ciências Médicas e Pesquisa de Maharishi Markandeshwar, Haryana (n=88). Resultados: A idade dos pacientes variou de 5 a 88 e houve predominância de pacientes do sexo feminino. Dos casos estudados, 35% foram diagnosticados como líquen plano, 11% como lúpus eritematoso, 13% como eritema multiforme, 30% como pênfigo vulgar e 11% como grupo penfigoide. Manifestações orais foram mais comuns entre os pacientes que sofrem de líquen plano (51%) e pênfigo vulgar (23%). A apresentação clínica mais comum encontrada foi o líquen plano reticular localizado predominantemente na mucosa bucal. Conclusões: É essencial para os dentistas conhecer estas patologias de modo a diagnosticá-las em uma fase precoce e encaminhar os pacientes para um tratamento adequado. Além disso, o exame intraoral deve ser incluído como uma prática rotineira nos serviços dermatológicos...

Radiographic assessment of agenesis of third molars andpara-radicular third molar radiolucencies in populationof age group 18-25 years old: a radiographic survey / Avaliação radiográfica da gênese e radiolucidezperirradicular de terceiros molares em população de faixaetária de 18-25 anos: um levantamento radiográfico

Introduction: Due to biological, cultural and evolutionary changes with time, humans have experienced adecreased dependency on all tooth types. Because of this, the number of certain teeth which are no longernecessary for function are either getting increasingly impacted or are not developing at all. This is especiallythe case where third molars are concerned. Objective: To assess the prevalence of agenesis of third molarsand para-radicular third molar radiolucencies in population of age group 18-25 years. Materials and methods:Five hundred patients of age ranging from 18 to 25 years old were selected randomly and subjectedto undergo conventional panoramic radiographic procedure. Results: 35.4% patients of our study populationrevealed agenesis of one of the third molars among the four third molars. Agenesis of right maxillarythird molar is quite significant as p = 0.030; and only 3.4% revealed the prevalence of para-radicular thirdmolar radiolucencies. Conclusion: As time goes by, agenesis of the third molars is increasing, so they canbe considered as vestigial. However, etiology of the para-radicular third molar radiolucencies is unknown.Hence, further research is needed to describe the nature as well as outcome of mandibular para-radicularthird molar radiolucencies.

Introdução: Em virtude de alterações biológicas, culturais e evolutivas com o tempo, os seres humanos têmexperimentado uma diminuição da dependência em todos os tipos de dentes. Por isso, os dentes que já nãosão necessários para a função estão ficando cada vez mais impactados ou não estão sequer se desenvolvendo.Este é especialmente o caso dos terceiros molares. Objetivo: Avaliar a prevalência de agenesia dos terceirosmolares e radiolucidez perirradicular em terceiros molares em uma população com faixa etária de 18-25 anos.Materiais e métodos: Quinhentos pacientes entre 18-25 anos foram selecionados aleatoriamente e submetidosa um exame radiográfico panorâmico convencional. Resultados: 35,4% dos pacientes da população deestudo revelaram agenesia de um dos terceiros molares entre os quatro terceiros molares. Agenesia do terceiromolar superior direito foi bastante significativa com valor p = 0,030 e apenas 3,4% revelaram a prevalência deradiolucidez perirradicular nos terceiros molares. Conclusão: Com o tempo, a agenesia dos terceiros molaresestá aumentando, de modo que podem ser considerados vestigiais. Porém, a etiologia da radiolucidez perirradicularnos terceiros molares é desconhecida. Portanto, mais pesquisas são necessárias para descrever a natureza,bem como as consequências de radiolucidez perirradicular em terceiros molares inferiores.

Pleomorphic adenoma of minor salivary gland: a case report

Introduction : World literature suggests salivary gland tumors account for less than 3% of the head and neck tumors and benign pleomorphic adenoma of minor salivary glands arising de novo is very rare.Objective,case report and Conclusion: A case of pleomorphic adenoma of minor salivary glands in the buccal mucosa in a 55 year-old female is discussed. It includes review of literature, clinical features, histopathology, radiological findings and treatment of the tumor, with emphasis on diagnosis. The salivary glands may present with a diverse range of lesions presenting a challenge to even the most experienced clinician and pathologist. Resection with surrounding dispensable normal tissues is the key to successful treatment of such tumors.

Colposcopy: A new ray in the diagnosis of oral lesions.

Oral squamous cell carcinoma is the most common cancer of the oral cavity. The survival rates for oral cancer patients will significantly be improved provided lesions are detected and treated at the infancy stage. Early diagnosis is therefore of paramount importance. Histopathological examination is considered as the gold standard in diagnosing oral lesions. Therefore, the selection for a biopsy site is highly significant. In this article, we present a current review of the colposcope and oral application of the colposcopy technique and its use as an adjunct in the early diagnosis of premalignant and malignant lesions of the oral mucosa. We stress upon the fact that colposcopy (direct oral microscopy) of oral mucosal lesions helps in selecting more representative sites for biopsy than routine clinical examination alone. Because of its precision, versatility, ease of use, and being a non-invasive technique, colposcopy might prove to be a useful step toward continuing to learn and improve the care for our patients.
