The aim of this study was to investigate apical microleakage after use of the Resilon system in comparison with gutta-percha. The materials used were 54 mesial roots of mandibular molars with an apical curvature of 20-40 degrees . The root canals were instrumented with the Prosystem GT(R) and obturated with: Group I: Gutta-percha + Sealer by lateral condensation (n = 25); Group II: Gutta-percha...

Lateral canals establish connection between the main root canal and periodontal ligament. The necrotic tissues and bacteria residing in the lateral canals are difficult to remove by mechanical and chemical cleaning and this influences filling the root canal efficiently and the outcome of the root canal therapy. The aim of this study was to evaluate the filling of artificially prepared lateral c...

INTRODUCTION Present study evaluated the fracture resistance of endodontically treated teeth filled with Gutta percha and a new resin based obturating material (Resilon). MATERIALS AND METHODS A total of 150 freshly extracted Mandibular premolar with fully formed apices were selected and decoronated at cemento-enamel junction (CEJ). Teeth were divided into Group A and Group B of 75 teeth each...

The aim of the study was to evaluate the distribution of Roekoseal Automix sealer using three different obturation techniques. Forty-five single-rooted extracted human teeth were prepared in a crown-down manner using ProFile instruments. After instrumentation the specimens were filled using Roekoseal Automix with the cold lateral condensation, Thermafil and Obtura II techniques. Each root was s...

This project was designed to determine how a new resin based obturation material compared with traditional gutta-percha techniques in its ability to fill the prepared root canal space. Eighty single-rooted palatal and distal roots of extracted human first molars were used. The root canals were instrumented with hand and rotary files and divided into four groups. Gutta-percha and the new resin b...

This study was done to evaluate new manufactured rotary spreaders one made from stainless steel material and second from nickel titanium and compared them with conventional finger spreader for their affect on the amount of gutta percha (in mg) that can be applied to fill the root canal and evaluation of apical extension of first, second, third and fourth auxiliary gutta percha cones for the sta...

introduction: the purpose of this study was to compare the apical sealing ability of lateral and vertical compaction techniques following immediate and delayed post space preparation. materials and methods: seventy-four distal and palatal roots of human extracted molars were instrumented and randomly divided into 4 experimental groups (n=15), two experimental control groups (n=5), and two posit...

Vertical loads and root surface strains in extracted teeth during lateral condensation using finger and hand spreaders were measured and compared with loads and strains at fracture. Six groups each of 10 teeth were tested: maxillary central incisor, premolar and molar; and mandibular incisor, premolar and molar. Root strains were measured using strain gauges mounted on the apical and middle thi...

Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. It typically affects permanent maxillary lateral incisors, central incisors, and premolars. This paper describes the root canal treatment of Oehlers' type II dens invaginatus in maxillary left lateral incisors. A 16-year-old boy presented to the Fa...
