Management of recurrent polymorphous low grade adenocarcinoma: a case report / Manejo de adenocarcinoma polimorfo recorrente de baixo grau: relato de caso

The Polymorphous Low Grade Adenocarcinoma (PLGA) is a common minor salivary gland carcinoma. It mostly affects the buccal mucosa and retromolar region, but the palate is an unusual site. As the carcinoma is low grade the recurrence is also uncommon. Our patient had a PLGA initially in the palate which was treated initially through surgical management but had a recurrence after four years. Hence we planned a partial maxillectomy along with level I nodes. Post-operatively follow-up is successful till date. So the management of a recurrent PLGA through careful surgery and post-operative follow ­up with prosthetic rehabilitation is discussed in this article... (AU)

Mucoepidermoid Carcinoma Of The Hard Palate: A Case Report

Mucoepidermoid Carcinoma is an epithelial salivary gland tumor which usually occurs in younger patients and females. The following case report deals with a case of mucoepidermoid carcinoma in a 38-year-old male patient who reported with a chief complaint of swelling in the palatal region for 1 year. At first, it was diagnosed as a benign minor salivary gland tumor of the palate. Upon incisional biopsy, an impression was made according to the features present. Complete excision of the lesion was done which was then diagnosed as mucoepidermoid carcinoma. The conflict between whether the lesion was a benign minor salivary gland tumor of the palate or a malignant counterpart, was resolved and confirmed after excisional biopsy.The article focuses on various diagnostic aspects of this tumor and its surgical management

Classification and management of dental caries. New concepts.

There has been a tremendous change in the understanding of carious lesion in all aspects from pathogenesis to prevention. The profession has also seen a revolutionary change in the material science and technology. In spite of these changes, the caries classification provided by Dr. G. V. Black remains unchanged, deterring the radical changes needed in the understanding of caries as a disease process. This article propose a new classification of dental caries to suit the present day changes in the related area. The article opens by highlighting the changes and limitations in the existing classification. The logical and advantageous outcome of the new classification is projected at the end emphasizing the need to change in conservative dentistry and education.

Crystal growth technique for composite resin bonding. A SEM study.

This study aimed to compare the surface structure of the exposed enamel and dentine treated with acid etching and various concentrations of crystal growth agents (CGA) under Scanning Electron Microscope (SEM). Fifteen maxillary central incisors which fulfilled the inclusion and exclusion criteria were used as samples. The acid used for etching the enamel was 37% orthophosphoric acid and CGA's were 2%, 5% and 10% for micacid saturated with ammonium sulfate. The samples were divided into 5 groups and expect control group others were subjected to various surface treatments. They were observed under SEM at X 1000 magnification. The acid etched enamel surface structure was similar to the previously published reports. Maximum crystal growth on enamel and dentin were observed with 5% CGA. The surface irregularity produced by crystals were similar to acid etched surface.
