Aim: The aim of the present studywas to compare the effect of a calcium sodium phosphosilicate (NovaMin®) desensitizing agent (a bioactive glass) on both cervical and midcoronal dentine sections using scanning electron microscopy (SEM). Methods: Sections of both cervical and mid coronal dentine were prepared and etched with 5% citric acid for 5 minutes; these sections were then brushed with 2mg...

PURPOSE Dentin hypersensitivity is a potential threat to oral health. Laser irradiation may provide reliable and reproducible treatment but remains controversial. The present study aimed to evaluate the effects of CO2 or erbium-doped yttrium aluminium garnet (Er:YAG) laser therapy, and to assess mineral content. METHODS Eighteen human single-rooted teeth affected with advanced periodontitis w...

Cell surface proteins SspA and SspB in Streptococcus gordonii and SpaP in Streptococcus mutans are members of the antigen I/II family of polypeptides produced by oral streptococci. These proteins are adhesins and mediate species-specific binding of cells to a variety of host and bacterial receptors. Here we show that antigen I/II polypeptides are involved in the attachment of oral streptococci ...

INTRODUCTION This study was carried out to investigate the effect of 808nm diode laser irradiation on dentinal tubules of root canal wall. MATERIALS AND METHODS Twelve single-rooted teeth were used. After cleaning and shaping with rotary instruments by the crown down technique, the smear layer was removed by alternating irrigation with EDTA and sodium hypochlorite. The teeth were then randoml...

Dentinal hypersensitivity has been referred to as one of the most painful and chronic dental conditions, with a reported prevalence of between 4% and 57% in the general population and a higher prevalence in periodontal patients. It may also occur as a result of, or during, dental treatment. Clinicians must screen for dentinal hypersensitivity and diagnose by exclusion, determine appropriate tre...

Introduction: Dental caries is dramatically common among people. The aim of this study was to evaluate the agreement of paper prints and film prints and monitor in detection of dentinal caries in digital panoramic radiography. Materials and methods: In this analytical study, radiographic images of 150 patients referred to a private clinic and who needed panoramic radiographs for various rea...

AIM This in vitro investigation aimed to study by means of scanning electron microscope the morphological changes in hard dental tissues after using several different methods for caries removal and cavity preparation. MATERIALS AND METHODS Twenty freshly extracted human teeth with carious lesions were used in the study. They were assigned to four groups depending on the method used for prepar...

OBJECTIVES This in vitro study aimed to investigate the ability of Candida albicans (C. albicans) and Enterococcus faecalis (E. faecalis) to penetrate dentinal tubules of instrumented and retreated root canal surface of split human teeth. MATERIALS AND METHODS Sixty intact extracted human single-rooted teeth were divided into 4 groups, negative control, positive control without canal instrume...

The response of neural elements to a dentin injury was morphologically investigated in rat molars by use of immunostaining for neurofilament protein (NFP). An artificially formed cavity in dentin by drilling rapidly caused the displacement of some odontoblasts into the exposed dentinal tubules, while others were detached from the predentin. The subodontoblastic nerve plexus consisting of NFP-im...
