Two novel SNPs in genes involved in immune response and their association with mandibular residual ridge resorption.

"Residual ridge resorption" (RRR) is a multifactorial condition involving bone resorption of the residual ridge. We investigated 10 single nucleotide polymorphisms (SNPs) in seven genes with the aim of identifying the genetic factors associated with RRR susceptibility. The study group included 96 RRR patients and 96 controls.

Mandibular residual ridge height in relation to age, gender and duration of edentulism in a Saudi population: A clinical and radiographic study.

Purpose: The purpose of this clinical and radiographic study was to evaluate the effect of age, gender and duration of edentulism on the amount of mandibular residual ridge resorption in a Saudi population.

Material And Methods: Partially and completely edentulous Saudi patients (50 male and 64 female) attending the outpatient clinics at College of Dentistry, King Saud University, Riyadh, Saudi Arabia were included. Current age, gender of subjects and date of start of edentulism were recorded.

A comparative evaluation of the effect of phototherapy of fiber post on its bond strength to dental composite.

The aim of the study was to evaluate the effect of diode laser as a phototherapy on surface treatment of fiber post and its bond strength to resin core build-up material. In this in-vitro study fifty fiber post of 1 mm tip-diameter and 20 mm length were used. The posts were mounted and randomly divided into 5 groups (n = 10) according to different surface treatment methods i.
