RESUMO
INTRODUCTION: Smoking is a hazardous habit which causes definite changes in the oral cavity, consequently there exist changes in the mucosa when subjected to smoking. Palatal mucosa is first to be affected. The present study determines the palatal status in reverse smokers and conventional smokers. AIM: To study and compare the clinical, cytological and histopathological changes in palatal mucosa among reverse and conventional smokers. MATERIALS AND METHODS: Study sample was categorized into two groups. Group 1 comprised of 20 subjects with the habit of reverse smoking and Group 2 comprised of 20 subjects with the habit of conventional smoking. Initially, clinical appearance of the palatal mucosa was recorded, followed by a cytological smear and biopsy of the involved area among all the subjects. The findings were studied clinically, the specimens were analysed cytologically and histopathologically, and compared among the two groups. RESULTS: The severity of clinical changes of the palatal mucosa among reverse smokers was statistically significant when compared to those of conventional smokers. There was no statistically significant difference observed in cytological staging between the groups with a p-value of 0.35. The histopathological changes in both the groups showed a significant difference with a p-value of 0.02. A significant positive correlation was observed between the clinical appearance, and cytological, histopathological changes. CONCLUSION: Profound clinically aggressive changes were observed in group I compared to group II. Severity of dysplastic changes have been detected in few subjects through histopathological examination irrespective of no prominent clinical and cytological changes observed among the two groups.
RESUMO
Introduction: Oral tuberculosis is a chronic granulomatous disease caused by Mycobacterium tuberculosis. According to the World Health Organization (WHO), nearly 2 billion people are infected with tuberculosis. Objective: To report a rare case of oral tuberculosis with ulcers at two different sites. Materials and methods: In order to emphasize the need to consider tuberculosis in the differential diagnosis of non-healing ulcers of oral cavity and the role of oral physician in preventing the spread of such lesions, this article presents a case of oral ulcers at two different sites, diagnosed as tuberculosis ulcer. Results: Oral cavity, which is considered to be a mirror of systemic health, rarely manifests tuberculosis. With increasing number of tuberculosis cases and unusual form of the disease in the oral cavity, the cases are likely to be misdiagnosed. Conclusion: An oral clinician should have a thorough knowledge of tuberculosis and its oral manifestations.
Introdução: A tuberculose oral é uma doença granulomatosa crônica causada pelo Mycobacterium tuberculosis. Segundo a Organização Mundial da Saúde (OMS), cerca de 2 bilhões de pessoas estão infectadas com tuberculose. Objetivo: Relatar um caso raro de tuberculose oral com úlceras em dois locais diferentes. Materiais e métodos: Para realçar a necessidade de considerar a tuberculose sob o diagnóstico diferencial das úlceras não curadas da cavidade oral e o papel do dentista na prevenção da propagação de tais lesões, este artigo apresenta um caso de úlceras orais em dois locais diferentes, diagnosticados como úlcera de tuberculose. Resultados: A cavidade oral, considerada como um espelho da saúde sistêmica, raramente manifesta a tuberculose. Com um número cada vez maior de casos de tuberculose e a forma não usual da doença na cavidade oral, os casos são frequentemente diagnosticados erroneamente. Conclusão: O dentista clínico geral deve ter um conhecimento profundo da tuberculose e de suas manifestações orais.
