Comparative evaluation of alkaline ionized water and normal water on oral microbial flora: An study.

Background: Various artificial chemical agents have been evaluated over many years with respect to their antimicrobial effect in oral cavity. The gold standard for removal of plaque is usage of chlorhexidine, but it can cause alteration in taste sensation and staining of teeth. Electrolytes and oxidizing water may be useful against microbes, but its clinical application has still not been evaluated.

Marginal and internal fit of cobalt-chromium copings fabricated using the conventional and the direct metal laser sintering techniques: A comparative study.

Background And Objectives: This study seeks to evaluate and compare the marginal and internal fit of cobalt-chromium copings fabricated using the conventional and direct metal laser sintering (DMLS) techniques.

Methods: A master model of a prepared molar tooth was made using cobalt-chromium alloy. Silicone impression of the master model was made and thirty standardized working models were then produced; twenty working models for conventional lost-wax technique and ten working models for DMLS technique.

Evaluation of single-tooth replacement by an immediate implant covered with connective tissue graft as a biologic barrier.

Background And Objectives: The aim of the present study was to evaluate the survival rate of Screw-Vent(®) immediate implants augmented with sub epithelial connective tissue graft for single-tooth replacement for 1 year.

Materials And Methods: Ten patients (five men and five women), with the mean age of 25.3 years, were consecutively treated on the out-patient basis by the placement of Screw-Vent(®) dental implants in to the fresh extraction sockets in association of augmentation with sub epithelial connective tissue graft harvested from the palate, supporting single crowns.
