The aim of this study was to examine and compare vertical forces exerted during root canal obturation with the cold lateral condensation technique, Thermafil technique and ProTaper guttapercha. Fourty-five single-rooted permanent teeth were used in the study. All specimens were instrumented using the ProTaper rotating technique and were randomly divided into three experimental groups (n = 15 pe...

INTRODUCTION The aim of this study was to compare the outcome of root canal treatment using either Thermafil (TF; Dentsply Maillefer, Ballaigues, Switzerland) or the cold lateral condensation (CLC) obturation technique in teeth with periapical lesions and to investigate the influence on postoperative pain and treatment outcomes. METHODS After standardized root canal preparation technique, 112...

Successful endodontic treatment depends on thorough knowledge in root canal morphology, appropriate assessment of pulp chamber floor, critical interpretation of radiograph, and on biomechanical preparation followed by three dimensional obturation of root canal system. The possibility of additional root /canal should be considered even in teeth a low frequency of abnormal root canal anatomy. Man...

OBJECTIVE To investigate the apical sealing ability of glass ionomer and resin-based root canal obturation systems in comparison to a conventional vertical compaction of warm guttapercha. METHODS Forty-five extracted human teeth were randomly assigned into 3 groups of 15 each: a resin-based (EndoRez), a glass ionomer-based (Activ GP), and a conventional gutta-percha plus pulp sealer obturatio...

Two surgical cases are presented in which retrograde instrumentation of the root canal was accomplished with sonic or ultrasonic instruments. The canals were obturated from a retrograde direction with thermoplasticized gutta-percha and root canal sealer. Success of these treatment approaches is attributed to thorough debridement and satisfactory obturation with equipment only recently available...

OBJECTIVE The aim of this study was to compare the presence of voids in root fillings performed in oval and ribbon-shaped canals with two root filling techniques, lateral compaction technique (LCT) or hybrid technique (HT), a combination of a gutta-percha masterpoint and thermoplastic gutta-percha. Furthermore, the obturation time for the two techniques was evaluated. MATERIALS AND METHODS Si...

Mandibular premolars usually have a single root and canal. Complex root canal system with atypical variations is a common finding among them. Failure to identify such a one can affect the prognosis of endodontic treatment. Apart from knowledge and sophisticated instruments, a good clinical expertise is required in identifying, tracing and treating such a root canal system. This case report is o...

The aim of this study was to evaluate the influence of two different irrigation protocols on artificial lateral root canal filling capacity using different obturation techniques. Sixty single-root human teeth were used. Two artificial lateral canals were created in the apical third. Root canals were instrumented up to a 45 K-file to the working length. Before each file, root canals were irrigat...

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...

introduction: several studies have evaluated the inflammatory reaction triggered by epiphany (eph), a contemporary endodontic sealer. however, they used conventional parameters, which need additional analysis to better understand the reactions induced by this sealer compared to other traditional sealers. methods and materials: the intensity and time span of tissue irritations for three endodont...
