The cleaning capacity of Hero 642 nickel-titanium files, complemented by the Hero Apical instruments in flattened roots, was determined by histological analysis, considering the area of action of the instruments on the coronal walls and the presence of remaining debris. Twenty-four single-canal, human mandibular incisors were divided into three groups and prepared as follows: GI, instrumented w...

The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat®, TC® System and Tagger's Hybrid Technique, in oval-shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n H...

BACKGROUND The aim of this study was to evaluate the bond strength of AH plus, Acroseal, and Adseal to the root canal dentin. METHODS A total of 36 single-rooted, mandibular premolar teeth were used. Root canal shaping procedures were performed with ProTaper rotary instruments (Dentsply Maillefer) up to size F4. The prepared samples were then randomly assembled into 3 groups (n = 12). For eac...

Background: Pulp and root canal space is enigmatic highly complex. Encountering rare has become a norm with the advancements in technology of materials types equipment. The success treatment depends on effective removal bacteria from whole pulp space. A high percentage missed reported for failure Endodontic therapy. Mandibular molars have complex anatomy. Two roots two canals mesial one to dist...

Introduction: This study aimed to evaluate anatomy and morphology of mandibular permanent molars using cone-beam computed tomography (CBCT) in a selected Iranian population.Methods Materials: CBCT images 638 first second (322 males 316 females) were included this vitro study. Number roots root canals, Vertucci’s configuration each root, radix paramolaris (RP), entomolaris (RE), C-shaped canals ...

Introduction: This study aimed to evaluate the central ability and root canal transportation of two types rotary files in curved molar canals using cone-beam computed tomography (CBCT) mesiodistal (MD) buccolingual (BL) directions.Method Material: A total 40 mesiobuccal mandibular first molars with an angle 25-35 degrees radius curvature 5 millimeters were randomly divided into groups 20 each. ...

Objectives: This study aimed to assess the efficacy of shockwave-enhanced emission photoacoustic streaming (SWEEPS) plus antimicrobial photodynamic therapy (aPDT) using indocyanine green (ICG) for elimination Enterococcus faecalis biofilm from infected root canals. Materials and Methods: thirty sound human single-canal teeth were chosen standardized have 12 mm length. The canals shaped prepared...

BACKGROUND/PURPOSE The objectives of this study were to identify the bilateral distolingual (DL) canals / roots of the mandibular first molars and second mesiobuccal (MB2) canals of the maxillary first molars in the same Turkish individuals using cone-beam computed tomography (CBCT). MATERIALS AND METHODS A total of 150 CBCT images including all mandibular and maxillary first molars were retr...

Background/Aim: To evaluate void volumes in oval-shaped root canals obturated with three different obturation systems using microcomputed tomography (micro-CT). Material and Methods: Twenty-four distal roots of mandibular molar teeth were prepared randomly divided into groups (n = 8 each group). The single cone (SC), GuttaCore (GC), warm vertical compaction (WVC) techniques. Each specimen was s...

AIM To analyse the gutta-percha filled area of C-shaped molar teeth root filled with the modified MicroSeal technique with reference to the radiographic features and the C-shaped canal configuration. METHODOLOGY Twenty-three mandibular second molar teeth with C-shaped roots were classified according to their radiographic features as: type I--merging, type II--symmetrical and type III--asymmet...
