Influence of three different types of desensitizing agents on bond strength of etch-and-rinse and self-etch adhesive system on dentin: An study.

Aim: To determine the effect of three different dentin hypersensitivity treatment procedures on the microtensile bond strength of etch and rinse and self-etch adhesive system.

Materials And Methods: Eighty extracted intact human permanent lower premolars were decoronated, and dentin was exposed on the buccal surface. The teeth were randomly assigned to two experimental groups of 40 teeth each: etch and rinse system or self-etch system.

Comparative Evaluation of Novel Bulk Fill Resin Composites with Conventional Composites for Microleakage Formation - A Steromicroscopic Study.

Aim: The purpose of this study was to assess and compare microleakage of two novel bulk-fill resin composites with traditional incremental composites.

Materials And Methods: Standardized conservative Class II cavities were made on 120 sound maxillary premolars having approximately 4 mm of width with 2 mm gingival extension below CEJ keeping all line angles round and cavosurface margins beveled. Samples were categorized into the group of three (n = 40), based on composites used; Smart Dentine Replacement (SDR), X Tra Fill, and Z350 XT.

Associated Injuries in Maxillofacial Trauma: A Study in a Tertiary Hospital in South India.

Aim: Maxillofacial trauma when associated with concomitant injuries has a significant potential for increased morbidity. This study aims to identify the causes of trauma, evaluate the types of associated injuries and to highlight the significance of multi professional collaboration in sequencing of treatment.

Patients And Methods: A total of 300 patients who reported to the casualty of a tertiary Hospital in Karnataka with facial fractures were enrolled.

The facial skeleton: Armor to the brain?

Background: With the development of urban setting worldwide, the major issue of concern is the increase in the mortality rate in the population due to road traffic accidents. The face, being the most exposed region is susceptible to injuries and maybe associated with injuries to the adjacent neuro-cranium. The literature has conflicting views on the relationship between facial fractures and head injuries with some authors opining that the facial skeleton cushions the brain while some other authors claim that the facial fractures act as indicators for head injuries.

Albright hereditary osteodystrophy: a case report.

A dental practitioner with an eagle's eye can diagnose many hidden disease through careful examination of the oral cavity. One such hereditary metabolic disorder is Albright hereditary osteodystrophy (AHO). Characteristic presentations in an individual affected by AHO were short stature, obesity and brachydactyly especially of 4(th) and 5(th) digits, which are the phenotypic features of genetic mutation.

Expression of Endoglin (CD-105) and Microvessel Density in Oral Dysplasia and Squamous Cell Carcinoma.

Objective: To assess the expression of Endoglin (CD-105) and Microvessel Density in clinically normal oral mucosa of non-tobacco and tobacco habituated patients & also histopathologically confirmed cases of oral squamous cell carcinoma (OSCC) patients.

Materials And Methods: Twenty cases of clinically normal oral mucosa with tobacco habituation in the form of chewing or smoking, 20 histopathologically confirmed cases of OSCC and twelve normal healthy oral mucosal cases without tobacco habituation in any form, served as control group, were immunohistochemically analysed for expression of Endoglin (CD-105). Chi-square test is used to determine statistical analysis and significance.

Cyclin d1 gene expression in oral mucosa of tobacco chewers"-an immunohistochemical study.

Objective: The objective of the present study was to evaluate the expression of cyclin D1 in normal oral mucosa of both non tobacco habituated and tobacco habituated individuals histologically and also compare and correlate cyclin D1 expression with histopathologically confirmed cases of oral squamous cell carcinomas.

Study Design: The present study involved 20 cases of tobacco habituated individuals with normal oral mucosal tissue and 20 histopathologically confirmed cases of squamous cells carcinomas. Twelve cases of non tobacco habituated individuals served as control group.
