Aims and Objectives To evaluate the influence of indirect chair-side polymerization of resin composite cores on the fracture resistance of overlaying IPS e.max Press crowns. Materials and Methods Root canals of 60 extracted premolars were prepared to receive #2 fiber posts after the crowns were sectioned 2 mm above the cervical line. In Groups 1-3 (n = 10 each), posts were luted to the prepar...

Background and aims. Various factors influence the interfacial bond between the fiber posts and root canal dentin. The aim of the present study was to evaluate the effect of pre-warming of resin cement on the push-out bond strength of fiber posts to various segments of root canal dentin. Materials and methods. In this in vitro study, 40 single-rooted human premolars were decoronated and underwe...

OBJECTIVES To compare the apical sealing ability of four root canal sealers. MATERIAL AND METHODS Forty extracted human maxillary canines were instrumented 1 mm short of the anatomical apex and randomly assigned to four groups (n=10), according to the root canal sealer used for obturation: Endofill, AH Plus, EndoREZ and Epiphany. Root canals were obturated with gutta-percha points, except for...

Introduction. Milled precision bar with the lateral additions of two attachments could significantly contribute to primary and secondary retention partial denture overdenture. This clinical case demonstrates stability mandibular overdenture using milled coronally positioned attachments. Case report. A sixty-five years old male patient had preserved canine roots in lower jaw. Semicircular metal-...

Objective: There is a lack of high-quality evidence on the efficacy non-instrumentation endodontic treatment (NIET) in primary molars, compared to conventional technique. This protocol describes multicenter randomized clinical trial that aims evaluate NIET technique for molars using paste containing antibiotics (chloramphenicol and tetracycline – CTZ group) control group root filling with zinc ...

The purpose of this study was to measure the bond strength of dual-cure resin cement at different regions of root canal dentin using three kinds of curing method. Thirty-six extracted bovine teeth were used. Each root was sectioned vertically into halves. Their pulpal dentin walls were polished flat and then applied with two dual-cure resin cements (Bistite II, Panavia F), and divided into thre...

OBJECTIVES The aim of this study was to evaluate the influence of two adhesive systems and the post space region on the degree of conversion of dual resin cement and its bond strength to root dentin. MATERIAL AND METHODS One three-step etch-and-rinse (All-bond 2, Bisco) and another one-step self-etch (Xeno III, Dentsply) adhesive systems were applied on 20 (n=10) crownless bovine incisors, at...

OBJECTIVES The aim of this study was to evaluate the fracture resistance of endodontically treated teeth filled with a resin-based obturation material using two different chelating agents. METHODS AND MATERIALS Forty extracted single-canal human teeth were prepared, instrumented, and randomly divided into three groups: Group 1 (n=15) received a final flush with 10 ml of neutralized 17% EDTA, ...
