The endodontic treatment of maxillary molar with an aberrant root canal morphology can be diagnostically and technically challenging.1 Unusual root canal morphology in multirooted teeth is a constant challenge for diagnosis and successful endodontic treatment. Presence of extra canals, lateral canals, deltas is commonly encountered.2 This case report is presented to illustrate and describe the ...

The aim of this study was to compare the cross-sectional area of sealer plus voids of Epiphany sealer surrounding root fillings completed with Resilon cones and laterally compacted gutta-percha. The root canals of extracted human mandibular premolars were prepared to a final size of 40 (0.06 taper). The teeth were then randomly assigned into 2 groups (n = 12/group) for the filling procedures in...

OBJECTIVE The aim of this study was to evaluate whether the gap between the post restoration and the remaining root canal filling had an impact on the periapical health of endodontically treated teeth in a Turkish subpopulation. STUDY DESIGN Digital panoramic radiographs, evaluated for this cross-sectional study, were randomly selected from files of patients who attended to Yeditepe Universit...

1. The infected root canal space cannot be cleaned and disinfected with the standard root canal protocol using an aggressive procedure with endodontic files. 2. After the disinfecting phase of treatment has been completed, filling the root canal is difficult because the open apex provides no barrier for containing the root filling material without impinging on periodontal tissues. 3. Even after...

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...

INTRODUCTION One of the key factors in successful endodontic therapy is to adequately fill the root canals. The aim of this in vitro study was to compare the quality of four different root canal obturation techniques: cold lateral condensation (CLC), warm vertical condensation (WVC), Obtura II (OII) and Gutta Flow (GF) by using micro-computed tomography (micro CT). MATERIALS AND METHODS A tot...

The aim of the present study was to evaluate the effect of calcium hydroxide dressing on the bond strength of three commercially available endodontic sealers (MTA Fillapex, Sealapex, and AH Plus) to root canal dentin. Sixty slices of extracted human canines were obtained from cervical, middle, and apical root thirds. Root canals were standardized and specimens were filled and divided into six g...

introduction: the aim of this in vitro study was to evaluate the effect of mta-based sealer (mta fillapex), eugenol-based sealer (dorifill) and an epoxy resin sealer (ah plus) on the bond strength of fiber posts cemented with a self-etch adhesive. materials and methods: the root canals of 72 maxillary incisors were prepared using the step-back technique after removing/cutting off the crowns. th...

The sealing of the root canal system is of fundamental importance for successful endodontic treatment. To obtain an adequate apical seal, many factors must be considered such as the presence of smear layer and the sealer applied. After canal preparation, this layer must be removed because it prevents close contact between the dentinal walls and the sealing material. The goal of this study was t...

BACKGROUND Mature teeth with chronic apical abscesses characterized by intermittent discharge of pus through an associated sinus tract. This communication between oral mucosa and periapical inflammation is challenging for the sealing ability of root canal obturation material. Therefore, the study aim was to compare the outcomes of endodontic treatment using mineral trioxide aggregate (MTA) ceme...
