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...

AIM The purpose of this study is to achieve an effective method to remove root canal filling material from the root canal system. The study, thus, aims to evaluate the efficacy of the cleaning ability of two different rotary Ni-Ti systems; ProTaper Retreatment files and RaCe System compared to hand instrumentation with Hedstrom files for the removal of gutta-percha during retreatment. MATERIA...

background: root canal cleaning is an important step in endodontic therapy. in order to develop better techniques, a new generation of endodontic instruments has been designed. the aim of this study was to compare the effectiveness of manual k-files (mani co, tokyo, japan) and two rotary systems–mtwo (dentsply-maillefer, ballaigues, switzerland) and protaper (vdw, munich, germany)–for root cana...

The endodontic triad comprises of cleaning and shaping, disinfection and obturation. Success of root canal therapy is majorly achieved by proper cleaning and shaping. However, elimination of bacterial contaminants as well as necrotic debris of the canals requires the adjunctive use of irrigants. To achieve a satisfactory biological and mechanical preparation proper selection of endodontic instr...

conclusions the frequency of isthmuses in the mesial root of mandibular first molars was high. the results of clinical and surgical endodontic procedures may be affected by this aspect of root canal anatomy. results isthmus was present in 54% of teeth. the greatest frequency of isthmuses was observed in the 5 mm from the apex. the type v isthmus was the most prevalent isthmuses between all leve...

Successful root canal treatment is based on diagnosis, treatment planning, knowledge of tooth anatomy, and the traditional concepts of debridement, sterilization, and obturation. Several obturation techniques are available for root canal treatment. The choice depends on the canal anatomy and the unique objectives of treatment in each case. The two basic obturation procedures are lateral condens...

background: different techniques have been introduced to improve removing the calcium hydroxide intra-canal dressing. the purpose of this study was to compare the effi ciency of passive ultrasonic irrigation (pui) and rinsendo system in the removal of calcium hydroxide from root canal system. materials and methods: access cavities were prepared in 50 single-rooted anterior teeth. cleaning and s...

STUDY DESIGN Normal cervical sagittal length patterns were measured by magnetic resonance imaging (MRI). PURPOSE The aim of this study was to evaluate the relationship of sagittal length patterns between the cervical cord and the cervical canal in flexion-extension kinematics. OVERVIEW OF LITERATURE Cervical dynamic factors sometimes cause a cervical spondylotic myelopathy in elderly subjec...
