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.

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.
