Teeth have mechanical properties such as hardness, elasticity, viscoelasticity and fracture behaviour. In this review, the level of cadmium, lead, mercury, arsenic and etc. in human dental tissues was evaluated. In order to quantify these materials in teeth, various analytical techniques were used....
Different biological indicators such as blood hair and teeth have been used to evaluate lead and exposure in . However, up to date, it has not been established which is the best indicator to provide an assessment of internal exposure. The aim of the present study was to examine the levels ...
The aim of this research was to compare the abrasive effects of 3 different powders namely, Air flow (standard sodium-bicarbonate), Soda (not purified sodium bicarbonate- which is cheap and is used for polishing porcelain crowns) and (Jet fresh) aluminum trihydroxide.Materials and Methods. ...
The aim of this in vitro study is to investigate the effects of ozone and conventional cavity disinfectant on microleakage at the cavities which are restorated with different restorative materials. Ninety human molar teeth were used in this study. Black V cavities are prepared on buccal surfaces ...
Investigating the antimicrobial activity of different root canal filling pastes in deciduous teeth Purpose: The antiseptic property of root canal filling materials seems very important for the removal of residual pathogens from root canals. The aim of th... L Basir,A Khosravi,EA Montazeri,... -...
Objective: With a microcomputed tomography (microCT) imaging device, we aimed to quantitatively evaluate root canal fillings after commonly used endodontic procedures and also tested the suitability of microCT for this purpose. Materials and Methods: Eighty single roots were instrumented and obturated ...
Therefore, the aim of the present study was to assess resistance to cyclic fatigue of three NiTi files after immersion in NaOCl solutions in conditions similar to those used in clinical practice. Materials and Methods A total of 150 new Twisted Files (SybronEndo, Orange, CA), Revo S SU ...
Results were compared to that of when a methacrylate-based restorative system was used (3M ESPE Filtek Z350XT/Adper Ease One). Each increment was photoactivated (Bluephase, 1200mW/cm2) and the restored teeth stored for 24h at 37°C. Specimens were then longitudinally sectioned and the ...
A flowable resin composite was used for coronal build-up. The bonded teeth were sectioned and, after 24 h of water storage, stressed to failure using the microtensile tester (μTBS). Failed samples were analyzed by SEM inspection. HEMA-based DBAs were much more sensitive to pulpal pressure...
