Dental caries is a disease caused by Streptococcus mutans. The use of chlorhexidine to inhibit bacterial colonization has side effects such as tooth staining and can kill the normal flora when used long term. Epigallocatechin gallate (EGCG) chemical compound in form polyphenols from green tea catechins which have antimicrobial potency microorganism growth biofilm formation. Type Laboratory Expe...

AIM The goal of the study was to evaluate the effect of caries removal by three various methods on the permeability of class II composite resin restorations in primary molar teeth. MATERIALS AND METHODS Forty-five recently extracted primary molars were randomly assigned to three groups for three different methods of caries removal; group 1-mechanical, group 2-caries detector dye, and group 3-...

Tumors of the jaw bones and oral soft tissue are relatively common lesions in dogs. The aim of this study was to find cell markers to differentiate odontogenic epithelium from nonodontogenic epithelium for future research on the pathogenesis and pathology of odontogenic neoplasms in dogs. Keratin 14 and 19 staining was observed in odontogenic and nonodontogenic epithelium, whereas amelogenin an...

The histological processing of teeth is highly complicated because of containing both mineralized hard tissues and soft tissues. Depending on the type of decalcification agents used in processing, mild-to-severe deterioration in the tissue structure and inadequacies on clear staining of details by the histological stain may be observed. This study aims to compare the histological staining diffe...

The cellular source of fibronectin in the dental epitheliomesenchymal interface was studied in interspecies combinations of mouse and quail tissue. Species-specific fibronectin antibodies were produced by immunizing rabbits with purified mouse or chicken fibronectin and by absorbing both antisera with purified heterologous fibronectin and insoluble tissue extract. The absorbed antisera to mouse...

A meticulous knowledge of the root canal anatomy and morphology teeth is imperative to achieve successful also many other dental surgical treatments on them. The purpose this study was permanent maxillary Lateral incisors in Kerman. 100 extracted intact incisor were collected from different clinics anatomic morphologic characteristics selected samples such as number roots, apical curve directio...

BACKGROUND There are different mouthwashes containing chlorhexidine in different concentrations, as well as various excipients. Chlorhexidine induce stains or discoloration in teeth and mucous membranes. The aim of this work was to design a model to reproduce in vitro staining associated with the use of different mouthwashes containing chlorhexidine. MATERIAL AND METHODS We used as substrates...

statement of problem: due to the growing popularity of vital bleaching by carbamide peroxide it is imperative to understand the effect of such agents on enamel and dentine. purpose: the purpose of this study was to evaluate the effect of a 16% carbamide peroxide bleaching gel; vivastyle on enamel staining susceptibility. materials and methods: thirty bovine specimens were selected and randomly ...

INTRODUCTION On the basis of many clinical observations, some calcium silicate-based cements have a high potential for staining tooth tissue. This feature greatly limits the use of those cements, particularly for anterior teeth. This review aimed to provide a systematic evaluation of published in vitro studies to determine the effect of different calcium silicate-based cements on dental tissue ...
