The solubility of four dental cement bases was measured in simulated dentinal fluid and distilled water to evaluate the relevancy of the American Dental Association solubility test for cement bases in contact with vital dentine. A simulated dentinal fluid was formulated utilizing glucose, distilled water, and sterile human plasma. Cement-base samples were immersed in either distilled water or s...

Alizarin red, confocal laser scanning microscopy, dentinal tubules, human caries. Abstract Dentin morphology and the lesion found in dental caries have been studied for many years. It was first observed under optical microscopy, and later using electron microscopy. Confocal laser scanning microscopy (CLSM) applied with several fluorescent dyes such as alizarin red to see normal dentinal tubules...

a new design for replacing a missing anterior tooth is described. in this article, a lingually fixed partial denture, its advantages, disadvantages, indication and contraindications have been explained. the ability of this design to replace a single missing central or lateral incisor is discussed.

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...

We investigated the effects of lasers irradiation on the exposed dentinal tubule. Human tooth specimens with exposed dentinal tubule orifices were used. Three types of lasers (CO(2) laser, Er:YAG laser and Ga-Al-As laser) were employed. The parameters were 1.0 W in continuous-wave mode with an irradiation time of 30 s for the CO(2) laser, 30 mJ in continuous-wave mode with an irradiation time o...

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...

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...

Dental hypersensitivity due to exposure of dentinal tubules under the enamel layer to saliva is a very popular and highly elusive technology priority in dentistry. Blocking water flow within exposed dentinal tubules is a key principle for curing dental hypersensitivity. Some salts used in "at home" solutions remineralize the tubules inside by concentrating saliva ingredients. An "in-office" opt...

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...
