According to FUJITA (1957) and TAKUMA (1960), the structure of the dentinal tubule wall in human dentin has been studied by KOLLIKER, NEUMANN, WALKHOFF, FLEISCHMANN, HANAZAWA, MEYER and ORBAN. Recently, TAKUMA and TSUCHIKURA (1950) found by means of the electron microscope that the dentinal tubules were lined with a hypercalcified area, and designated it as peritubular hypercalcified matrix. Th...

INTRODUCTION This study analyzed the in vivo microbiological status of the root canal systems of mesial roots of mandibular molars with primary apical periodontitis after 1- or 2-visit endodontic treatment. METHODS Mesial root canals were instrumented by using either a combination of K3 and LightSpeed instruments (mesiobuccal canals) or the ProTaper system (mesiolingual canals), with 5% NaOCl...

OBJECTIVE The objective of our study is to analyse (with the help of scanning electron microscopes) the quality of the dental root surface and the appearance of dental cracks after performing apical preparations using two different types of ultrasonic tips. STUDY DESIGN We used 32 single-rooted teeth that underwent a root canal and apical resection. Afterwards, the teeth were divided into 4 g...

introduction: dentin hypersensitivity (dh) is characterized by tooth pain arising from exposure of dental roots. in this study the efficiency of neodymium yttrium-aluminum-garnet (nd:yag) laser in association with graphite on dentinal surface changes as the alternative to the treatment of dh was evaluated. methods: sixteen noncarious human third molars were collected and sectioned into 5 parts ...

OBJECTIVE The aim of this study was to investigate the different smear layer morphologies produced by instrumentation with a hand curette and a periodontal sonic scaler for potential removal by soft acidic solution. The effect of a new oxalate-containing phytocomplex spray in preventing tubules exposure after citric acid solution application was also evaluated. METHODS Thirty recently extract...

This study evaluated the effects of the short-term use of a dentifrice containing nano-sized carbonate apatite (n-CAP) on the occlusion of the dentinal tubules using a scanning electron microscope (SEM) and an image analyser in vitro. One hundred human dentine specimens were wet ground with a silicone carbide papers and etched with 6% citric acid for 1 min to allow complete opening of the denti...

Abstract BACKGROUND AND OBJECTIVES: The purpose of this study was to analyze the microstructural changes caused by Carisolv gel on sound, demineralized, and denatured dentin. METHOD: A total of 48 freshly extracted human premolars and molars were collected and divided into 3 main groups, Group I contained 12 teeth with fractured dentinal surface, which were further divided into two subgroups IA...

AIM To compare the average sealer cement film thickness and the extent and pattern of sealer penetration into dentinal tubules in association with four obturation techniques in curved root canals. METHODOLOGY Mesial canals of 44 extracted mandibular molars were randomly divided among the SimpliFill, continuous wave, Thermafil and 0.04 matched taper (master cones) lateral compaction obturation...

OBJECTIVE To assess the strength of the evidence describing the effectiveness of alternative strategies to the detection and management of early occlusal caries and suspected occlusal dentinal caries. METHODS Nine detection and intervention decision points were identified as being central to the management of early occlusal caries and suspected occlusal dentinal caries, or suspicious areas. F...
