Successful root canal treatment is based on diagnosis, treatment planning, knowledge of tooth anatomy, and the traditional concepts of debridement, sterilization, an 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 condensa...

OBJECTIVES To determine the optimal timing for post space preparation of root canals sealed with epoxy resin-based AH Plus sealer in terms of its polymerization and influence on apical leakage. MATERIALS AND METHODS The epoxy polymerization of AH Plus (Dentsply DeTrey) as a function of time after mixing (8, 24, and 72 hours, and 1 week) was evaluated using Fourier transform infrared (FTIR) sp...

Abstract Introduction: The aim of this study was to evaluate the efficacy of two rotary instrument systems (ProTaper and Revo-s File) in removing calcium hydroxide residues from root canal walls Materials and Methods:Thirty human  maxillary incisors were instrumented with the ProTaper System up to the F2 instrument, irrigated with 2.5% NaOCl,and filled with a calcium hydroxide intracanal dr...

AIM The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy. BACKGROUND The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal trea...

BACKGROUND The aim of the study was to determine the root canal morphology of permanent mandibular incisor teeth in the Indian subpopulation with the use of cone beam computed tomography (CBCT). MATERIAL/METHODS CBCT images of 200 patients with 800 permanent mandibular incisors, fulfilling necessary inclusion criteria and aged 18 to 60 years were evaluated. The number of roots, number of root...

materials and methods: one hundred and thirty five mesial root canals of mandibular first and second molar teeth were selected. access cavities were prepared. after inserting a k-file size #10 into each canal, radiographs were taken. canal curvature was determined by measuring the schneider angle, canal access angle, as well as the canal radius, length, height and curvature starting distance on...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...

STATEMENT OF PROBLEM Studies reported that nearly 60% of endodontic failures have been attributed to inadequate obturation of the root canal system. Thus, complete obturation of the root canal system and proper apical seal are essential elements in the long-term success of root canal treatment. PURPOSE This study aimed to compare the apical seal of lateral condensation technique in the room a...
