Effect of Dietary Vitamin C on Orthodontic Tooth Movement in Rats.

Objectives: Bone remodeling occurs during orthodontic treatment; this process enables tooth movement. Many factors can affect bone remodeling at the cellular level, such as nutritional supplements that can affect tooth movement. The present study was designed to evaluate the effect of dietary vitamin C on orthodontic tooth movement in rats.

E-selectin and L-selectin polymorphisms in patients with periodontitis.

Background And Objective: Periodontitis is a multifactorial disease in which environmental and genetic determinant factors contribute to individual subjects susceptibility. A DNA polymorphism in the regulating region of adhesion molecule genes is suggested to modulate the molecules physiological effects. The aim of this study was to investigate the genetic association between the E-selectin Ser128Arg and L-selectin Phe206Leu polymorphisms and periodontitis.

Interleukin-4 (C-590T) and interferon-gamma (G5644A) gene polymorphisms in patients with periodontitis.

Background And Objective: Periodontitis is a multifactorial disease and immunologic and genetic factors have an important role in its pathogenesis. Mutation in the promoter regions of the interleukin-4 and interferon-gamma genes has been reported to modify the protein expression. The objective of this study was to evaluate the possible role of interleukin-4 (C-590T) and interferon-gamma (G5644A) polymorphisms in the susceptibility to periodontitis.

Oral Fluid Antibody Detection in the Diagnosis of Gastric Helicobacter pylori Infection.

The aim of this study was to evaluate an enzyme - linked immunosorbent assay (ELISA) for the detection of anti - helicobacter pylori (H. pylori) specific IgG antibodies in specimens of oral fluid.All subjects over the age 18 years undergoing endoscopy for any reason were asked to participate in the study.
