NSK reciprocating handpiece: in vitro comparative analysis of dentinal removal during root canal preparation by different operators.
The purpose of this study was to assess dentin removal during root canal preparation by different operators using a NSK reciprocating handpiece. Eighty-four human single-rooted mandibular premolars were hand instrumented using Triple-Flex stainless-steel files (Kerr) up to #30, weighed in analytical balance and randomly assigned to 4 groups (n=21). All specimens were mechanically prepared at th...
متن کاملComparative Evaluation of Dentinal Microcrack Incidence After Root Canal Preparation by BioRaCe and Edge Taper Platinum
Background and Aim: Preparation of root canal with rotary nickel-titanium (NiTi) instruments may potentially create microcracks that can lead to vertical root fracture. This study aimed to compare the incidence of crack formation by BioRaCe and Edge Taper Platinum systems in the mesiobuccal canals of extracted first mandibular molars. Materials and Methods: In this experimental study, 50 first...
متن کاملIn Vitro Evaluation of Dentinal Microcrack Formation during Root Canal Preparations by Different Niti Systems
The purpose of this study was to compare dentinal microcrack formation while using hand ProTaper (PT), ProTaper and ProTaper Next rotary files. Forty single rooted teeth were selected. 10 teeth were left unprepared and served as control, and the remaining 30 teeth were divided into 3 groups. After preparation with the file system selected, roots were sectioned 3, 6, and 9 mm from the apex, and ...
متن کاملIncidence of dentinal defects after root canal preparation: reciprocating versus rotary instrumentation.
INTRODUCTION The purpose of this study was to evaluate the incidence of dentinal defects after root canal preparation with reciprocating instruments (Reciproc and WaveOne) and rotary instruments. METHODS One hundred human central mandibular incisors were randomly assigned to 5 groups (n = 20 teeth per group). The root canals were instrumented by using the reciprocating single-file systems Rec...
متن کاملEvaluation of dentinal defect formation after root canal preparation with two reciprocating systems and hand instruments: an in vitro study
The purpose of this study was to evaluate the presence of dentinal defects after root canal preparation with hand instruments and two different reciprocating instruments. Sixty freshly extracted mandibular incisor teeth were selected for this in vitro study. On the basis of root length, mesiodistal and buccolingual dimensions, the teeth were allocated into three identical experimental groups (n...
