Mode of operation.?A small piece of the skin was taken up by means of an ordinary dressing forceps, and with a sharp scalpel it was cut, or rather shaved off, care being taken, if possiable, to avoid drawing blood. The piece removed was never more than an eighth of in inch in diameter, aud wa3 generally divided into two or more smaller portions upon the thumb nail, each division being placed se...

Background and Aim: The purpose of this study was to evaluate the effect of gutta-percha solvents on fracture resistance of endodontically treated roots. Materials and Methods: A total of 72 decrowned single canal human teeth were used. Eight of specimens were selected as a control group. Thereafter, the specimens were randomly divided into 2 groups (n= 32) according to gutta-percha solvent whi...

AIM Aim of this work was to carry out a comparative evaluation of the structural behaviour of different root canal posts (cylindrical, conical and triple conical) fitted in a second lower bicuspid and subjected to compression and bending test. MATERIALS AND METHODS This study has been carried out by numerical method of structural analysis of finite elements (FEM, Finite Element Method). Diffe...

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...

It is an "in vitro" study to evaluate the sealing ability of 3 root canal sealers using a dye leakage/clearing method. 40 lower incisors were instrumented by step-back technique and divided into 4 groups. The teeth filled with lateral condensation guta-percha varying sealer. Fill Canal, Sealer 26, N-Rickert tested compared control group in which guttapercha cones no seater used. Linear penetrat...
