Nd:YAG laser irradiation effect on apical intracanal dentin - a microleakage and SEM evaluation.
The purpose of this in vitro study was to evaluate the effect of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser irradiation on intracanal dentin surface by SEM analysis and its interference in the apical seal of filled canals. After endodontic treatment procedures, 34 maxillary human incisors were randomly assigned to 2 groups. In the negative control group (n=17), no additional treatment was...
متن کاملApical microleakage and SEM analysis of dentin surface after 980 nm diode laser irradiation.
This study evaluated the effect of 980-nm diode laser on apical microleakage and intraradicular dentin morphology. Roots of 110 mandibular incisors were used in the study: 92 for microleakage test and 18 for scanning electron microscopy (SEM). Roots were randomly assigned to 3 groups according to the irrigating solution (water, NaOCl and NaOCl/EDTA) and were divided into 3 subgroups according t...
متن کاملEvaluation of Different Dentin Adhesive Systems and its Effect on Apical Microleakage: An In Vitro Study
BACKGROUND Regardless of the technique and the material used, the goal of obturation remained the same that is to seal every portal of exit in the root canal system. It's not only the apical openings that need to be sealed but also lateral openings, coronal access opening and perforations if they exist failure of the adhesive root canal sealer has led to the idea of usage of dentin bonding agen...
متن کاملThe Effect of Intracanal Medicaments on Microleakage of Mineral Trioxide Aggregate Apical Plugs
INTRODUCTION The purpose of this in vitro study was to evaluate the effect of calcium hydroxide, double and triple antibiotic paste on the sealing ability of mineral trioxide aggregate (MTA) apical plugs. METHODS AND MATERIALS A total of 90 extracted teeth with single canals were prepared and randomly divided into four experimental groups (n=20). Intra-canal medicaments were applied for 3 wee...
متن کاملCombined FT-Raman and SEM studies of the effects of Er:YAG laser irradiation on dentin.
OBJECTIVE This study evaluated the molecular and morphological changes on dentin elements after Er:YAG laser irradiation. BACKGROUND DATA Spectroscopy studies reporting the effects of Er:YAG laser irradiation as an alternative to acid etching are needed to better understand the laser's effects. METHODS The occlusal one-third of the crown of six human third molars was removed. The dentin sur...
