RESUMO
INTRODUCTION: Sex determination in forensic anthropology is an essential step for medico-legal purposes and crucial for identification as the number of possible matches is reduced to 50%. Teeth are an excellent material for anthropological, genetic, odontological and forensic investigations as they are known to resist a variety of ante-mortem and post-mortem insults. Sexual dimorphism in tooth size and the accuracy of odontometric sex prediction is found to vary in different population and therefore it is necessary to determine specific population values in order to make identification possible. Hence, the present study was undertaken to evaluate the existence of sexual dimorphism in South Kerala population. AIM: To evaluate and estimate the degree of odontometric sexual dimorphism in all permanent teeth except third molars and the variations in odontometric dimensions between the left and right side teeth of the maxillary and mandibular arches in male and female groups. MATERIALS AND METHODS: The MesioDistal (MD) and BuccoLingual (BL) measurements of 28 teeth were estimated from the preorthodontic casts of 132 subjects; male group (66 males) and female group (66 females) of age range 15-25 years using digital Verniers' Caliper. The data obtained were analysed using SPSS version 17 and the Students' t-test for two independent samples. RESULTS: The MesioDistal (MD) and BuccoLingual (BL) parameters of all permanent teeth in the study group showed sexual dimorphism. Over 39% of the tooth variables showed reverse dimorphism. The comparison of mean values of MD and BL diameters of the maxillary and mandibular, right and left side teeth in male and female groups showed statistical significance in males whereas females show non-significant values in both MD and BL diameters. CONCLUSION: The study showed a varied percentage of sexual dimorphism and variation in the mean values of MD and BL dimensions in males, but not in females between right and left side teeth of the maxillary and mandibular arches of the study population.
RESUMO
Pleomorphic adenoma, the most common salivary gland tumor, consists of epithelial and mesenchymal components. Its morphologic complexity results from differentiation of tumor cells into fibrous, hyalinized, myxoid, chondroid and osseous areas. The diagnosis is made by the clinical and histo pathological examination. The treatment of pleomorphic adenoma is surgical excision. Malignant transformation, though rare, has been reported. In this article, we report a case of pleomorphic adenoma with literature review.
El adenoma pleomórfico es el tumor más frecuente de las glándulas salivales, con componentes epiteliales y mesenquimales. Su complejidad morfológica es resultado de la diferenciación de las células tumorales en las zonas fibrosas, hialinizadas, mixoides, condroides y óseas. El diagnóstico se realiza mediante el examen clínico e histopatológico. El tratamiento de adenoma pleomórfico es la escisión quirúrgica. La transformación maligna, aunque rara, ha sido reportada. En este artículo se presenta un caso de adenoma pleomórfico con revisión de la literatura.
RESUMO
Lymphangioma is a benign hamartomatous hyperplasia of lymphatic vessels. Majority of them are superficial, but a few may extend deeply into the connective tissue. Intraoral lymphangiomas occur more frequently on the dorsum of tongue, followed by palate, buccal mucosa, gingiva, and lips. Surgical excision is the treatment of choice. The prognosis is good for most patients, although large tumors of neck/tongue may result in airway obstruction and death. This case report series discusses the clinical features, histopathology, and treatment of lymphangioma.
RESUMO
Mandibular second premolars, though generally are included under bicuspids, are of two types, the 2 cusp and 3 cusp varients. The aim was to determine the prevalence of the two varieties of mandibular second premolars in Kerala population, South India. This descriptive investigation was undertaken in two dental colleges of Kerala, India. A total of 2500 mandibular second premolars were examined for cuspal variations, groove patterns and gender predilection. A slight predilection (52.8 percent) for 2-cusp variety was noticed. The most frequent occlusal configuration were crescent shaped and Y groove patterns for 2 cusp and 3 cusp varieties of second premolars respectively...
Los segundos premolares mandibulares, aunque por lo general se clasifican como bicuspídeos, tienen dos tipos de variantes, de 2 y 3 cúspides. El objetivo de esta investigación fue determinar la prevalencia de las dos variedades de segundos premolares mandibulares en población Kerala, en el sur de la India. Esta investigación descriptiva se realizó en dos Universidades dentales de Kerala, India. En un total de 2500 segundos premolares mandibulares se examinaron las variaciones cuspídeas, patrones de surcos y la predilección según sexo. Se observó una ligera predilección [52,8 por ciento] para la variedad de 2 cúspides. Las configuraciones oclusales de los segundos premolares más frecuentes fueron los patrones de surco en forma de media luna y en forma de Y para las variantes de 2 y 3 cúspides, respectivamente...
