ABSTRACT
Mucoepidermoid carcinoma is the most common malignancy of the salivary glands. It comprises 5–10% of all salivary gland tumours. It is histologically comprised of a mixture of mucous cells, intermediate cells, squamoid or epidermoid cells. This tumour may also demonstrate clear cell, oncocytic or columnar cells. There is arguably no other salivary gland tumour in which grading is as important to prognosis and therapy. Here we present a review with systematic approach to the histopathologic diagnosis, grading and prognosis, with a special emphasis on the biologic potential based on newer investigative modalities from the histopathologist perspective.
ABSTRACT
Dental caries is the progressive destruction of enamel, dentine and cementum, initiated by microbial activity at the tooth surface. It is one of the major problems in dentistry. On the basis of clinical features, it can be compared with krimidanta, which is one among the eight diseases of the tooth. In the management of krimidanta, medicines with actions of krimighna, paithya nashak, punah dhatu nirmaan and krumidantavarodh are used, which can relieve the toothache and prevent destruction of tooth structure. In this study, the efficacy of natural-ore bhasmas in krimidanta and its efficiency and durability over the most conventional treatment of lavanga oil application were compared. In this study, the patients of krimidanta (dental caries) were divided into two groups for two types of treatment. In type I, the patients were treated with natural-ore-based medicament and lavanga oil application, and in type II, the patients were treated with lavanga oil application only. From the results and observations of this study, it was concluded that natural-ore-based bhasmas provided better results in dantashoola, durgandhya, dantaharsha, aniyamit ruja and in krimidanta roga. In a nutshell, this clinical study has established that a combined therapy of natural bhasmas and lavanga oil gives better results than lavanga oil alone in the management of krimidanta.
