Objective: The goal of this article was to describe the importance of saving the natural remaining teeth and the fabrication of telescopic dentures as an alternative to the conventional removable dentures, to minimize the complete denture problems. Background: Telescopic dentures consist of an inner or primary telescopic coping which is permanently cemented to an abutment and an outer or secondary telescopic coping which is attached to the prosthesis. These copings protect the abutment from dental caries and thermal irritations and also provide retention and stabilization of the secondary coping. The secondary coping engages the primary copings to form a telescopic unit and it provides retention and stability to the prosthesis. Materials and Methods: An impression was made with a polyvinyl siloxane elastomer after the preparation of the abutments and the primary copings were fabricated on the cast which was obtained from the impression. After evaluating the fit of the primary copings on the abutments, they were cemented with glass ionomer cement. An impression of the cemented primary copings was made for the fabrication of secondary copings with retention beads, which were attached to the prosthesis. Conclusion: Telescopic overdentures have better retention and stability as compared to complete dentures, they improve the chewing efficiency and the comfort of the patient and they also decrease the alveolar bone resorption.

Background: In oral carcinoma much effort has been made to predict the prognosis of patients but a sound understanding of underlying cell biology is likely to need progress. Recently, attention has been directed towards tumour associated tissue eosinophils and mast cells and their role in the biologic behavior of tumours. Aim: The retrospective study was used to evaluate the influence of tumour associated tissue eosinophils and mast cells on prognosis of oral squamous cell carcinoma (OSCC). Material and methods: The follow-up, of histopathologically diagnosed thirty cases of OSCC, was carried out for minimum period of 3 years. Special stains are wonderful they allow us to see which we can not see clear with routine H&E stain.Tissue sections were stained with special stains, Carbol Chromotrope for tissue eosinophil and Toluidine blue for tissue mast cell staining. Result: The results of the present study shows that increase infiltration of tissue eosinophils and mast cells in OSCC, associated with favourable prognosis. Conclusion: We concludes that infiltration of tissue eosinophils and mast cells are indicators of favourable prognosis in OSCC. Thus quantitative assessment of eosinophils and mast cells are the most important aspects of the microscopic evaluation of OSCC. © 2011 Debta P, et al. Source

Background: Fine-needle aspiration cytology (FNAC) is used as the main initial diagnostic investigation for lumps in the head and neck region. Major salivary glands and some minor salivary glands are easily accessible; therefore, they are optimal targets for FNAC. The aim of this study was to discuss the advantages and pitfalls of FNAC as compared to histopathology in the salivary gland lesions. Material and methods: A total of 127 FNAC were carried out on salivary gland lesions from January 2006 to December 2010 - a 5-year period. Histopathological follow-up data were obtained in 56 cases. The study was conducted to examine the sensitivity, specificity, and accuracy of FNAC for salivary gland swellings in comparison with histopathology. Results: The male-to-female ratio was 2.4:1. Parotid gland was involved in 51.1%, submandibular gland in 37%, sublingual gland in 4.7%, and minor salivary glands in 7% of patients. There were 55.9% cases of non-neoplastic lesions and 44.1% cases of neoplastic lesions on biopsy. Sensitivity, specificity, positive predictive value, and negative predictive value of FNAC for malignant neoplastic lesions were 84.61%, 86.48%, 68.75%, and 94.11%, respectively, whereas for benign neoplastic lesions, they were 84.61%, 91.66%, 91.6%, and 85%, respectively. Conclusion: Fine-needle aspiration cytology is found to be a good sensitive and specific technique for the diagnosis of most of the salivary gland lesions. FNAC should be adopted as an initial investigation for all salivary gland swellings in conjunction with other investigations where appropriate. © 2011 John Wiley & Sons A/S. Source

An 11-year-old girl reported with an intraoral swelling which was noticed by her mother at birth and increased to its present size during the last year. A thorough clinical examination did not shed a conclusive diagnosis. This case highlights and discusses the history, clinical features, histologic features, differential diagnosis and the clinical management of this lesion. Awareness of such an entity will enrich the knowledge of the pediatric dentists who may be the first ones to encounter such cases in their day-to-day practice. Source

A 42-year-old woman presented with a gingival mass in the lingual vestibule of the mandibular incisor premolar region. On intraoral examination, the swelling was nontender and firm. Surgical excision was carried out and subsequent histopathological examination revealed areas resembling ameloblastoma-like and basaloid areas with atypical features suggestive of basal cell carcinoma. Immunohistochemical analysis was carried out to ascertain the origin of the lesion. © 2015 BMJ Publishing Group. All rights reserved. Source
