OBJECTIVE To characterise patterns of enamel thickness on deciduous (dm1, dm2) and permanent first (M1) mandibular molars and evaluate these against functional and morphological interpretative models. METHODS Histological sections of mesial and distal cusps from 69 unworn molars were produced and examined using transmitted light microscopy. Enamel cap area, dentine area, as well as average an...

AIMS The aim of this single-site, randomized, controlled, double-blind, 3-arm parallel study was to determine the effectiveness of a prophylaxis paste containing 15% calcium sodium phosphosilicate (CSPS; NovaMin(®) ) with and without fluoride in reducing dentine hypersensitivity immediately after a single application and 28 days following dental scaling and root planing. MATERIALS & METHODS O...

Mosasaur researchers have used varieties of tooth crown ornamentation as diagnostic and phylogenetic characters for decades. Such features include facets, flutes, striations, serrated carinae, coarse anastomosing texture. This study investigates the relative contribution dentine enamel to development these dental assesses possible homologies between structures. Histological analysis isolated mo...

dentin hypersensitivity (dh) is a relatively common painful condition among dental problems. although many studies have been performed regarding the diagnosis and treatment of dh, dental practitioners are still confused about the definite diagnosis and treatment.the use of lasers as a treatment for dentin hypersensitivity was first introduced in 1985. laser treatment in dentin hypersensitivity ...

INTRODUCTION Dentine hypersensitivity is characterized by acute, sharp pain arising from the exposed dentine, most commonly in response to thermal, tactile, or chemical stimuli, and which cannot be linked to any other pathological changes in the tooth or the environment. Therapy uses various impregnating agents in the form of solutions or gels and, in more recent times, laser. AIM The aim of ...

AIM This was to determine the temperature changes produced in dentine discs of primary teeth placed below a glass ionomer, microhybrid flow resin or microhybrid resin during the photocuring process with conventional halogen lamps and LEDs at different distances. STUDY DESIGN Experimental design. MATERIALS AND METHODS This in vitro study was carried out in the research laboratory of the Univ...

The purpose of this in vitro study was to assess the effect of hydrogen peroxide on the antibacterial substantivity of chlorhexidine (CHX). Seventy-five dentine tubes prepared from human maxillary central and lateral incisor teeth were used. After contamination with Enterococcus faecalis for 14 days, the specimens were divided into five groups as follows: CHX, H(2)O(2), CHX + H(2)O(2), infected...

Enamel tufts were exposed after decalcification of the enamel matrix and their fine structures and immunocytochemical characteristics were examined. Under the binocular microscope and the scanning electron microscope (SEM), enamel tufts appeared as corrugated ribbon-like structures located on the dentine parallel to the tooth axis. SEM observation disclosed enamel tufts as bundles of well exten...
