statement of problem: despite the wide range of new dental materials, there is still a need for biomaterials demonstrating high biocompatibility, antimicrobial effects and ideal mechanical properties. purpose: the aim of this study was to histologically evaluate the pulpal response to a conventional glass ionomer, a resin modified glass ionomer and a calcium hydroxide in human teeth. materials ...
Background and Aims: The vitality pulp tests are necessary for diagnosis of pulpal disease and differentiation between endodontic and non-endodontic diseases. Thermal and electrical tests are conventional methods for evaluation of pulp vitality. The purpose of this study was to evaluate the effect of thermal changes on the tooth response to the electric pulp tester. Materials and Methods: In t...
Background and Aims: Electric pulp tester is a valuable instrument to examine tooth’s pulp vitality. There is no agreement about the response of immature teeth to electric pulp tester and the reason is expressed as the failure of nerve fibers’ development. The aim of this study was to investigate the effect of patient’s age on the tooth response to electric pulp tester. Materials and Method...
introduction: accurate diagnosis of dental pulp conditions plays a key role in selection of an appropriate treatment including conservative vital pulp therapy (treatable pulp) or root canal treatment (untreatable pulp). the purpose of this study was to assess the accuracy of sensibility tests and the correlation of pulp response to sensibility tests with histologic pulp condition . material and...
conclusion both adhesive systems showed good biological compatibility. background to investigate pulp response to the application of two types adhesive systems (total-etch and self-etch) in human premolar teeth. materials and methods cavities limited to enamel walls in all margins with 2.5 mm depth were prepared on buccal surfaces of thirty three human premolars. the cavities were treated with ...
Diabetes mellitus is a chronic disease which affects the healing ability of the pulp and periodontium. The aim of the present study was to assess the histopathologic response of dental pulp to pulp capping using MTA or CEM cement in diabetic rats. Thirty two Wistar male rats aged between 8 and 10 weeks (weight: 200-250g) were divided into two groups of diabetic (n=16) and healthy (n=16) animals...
Evaluation of the effectiveness of cooling by cryosurgery in cat's inflamed pulp anesthesia Dr. S. Moradi* - Dr. A. Talati* - Dr. H. Hassanabadi** - Dr. P. Ghaziani*** - Dr. M. Ehsani**** *-Assistant Professor of Endodontics Dept. – Faculty of Dentistry – Mashhad University of Medical Sciences. **- Assistant Professor of Phisiotherapy Dept. – Faculty of Medicine – Mashhad University of Medical ...
The response of the dental pulp to calcium hydroxide or zinc oxide and eugenol cement was investigated histopathologically, using the germ-free and conventional rats. The upper first molar pulp was exposed with a p1/2 round bur through the mesial surface of the teeth and covered with the capping agents. The observation period was 1, 2, 4, 7, 10, 14 and 28 days postoperatively. The results obtai...
Background and Aims: Electric pulp testing is used for diagnosis of the pulp status. This test is technique sensitive and hence may elicit positive or negative false response in case of inaccurate use. The optimal site for placement of the probe tip has not been determined. The aim of this study was to evaluate the effect of pulp tester probe placement site on the response of maxillary teeth.Ma...
