The objective of this study was to investigate the correlation between CT depth, indentation depth determined by a new hardness tester (Cariotester), and the transverse microradiography (TMR) parameters, i.e., lesion depth and mineral loss. For that purpose, this study evaluated the feasibility of using Cariotester as a root caries diagnostic system and capability of Cariotester to detect effec...

The increasing interest in esthetics and the subsequent need to solve related problems such as dentin hypersensitivity and root caries have favored the development of many surgical techniques that permit the coverage of exposed roots. In this case, a 47-year-old female patient presented seeking resolution of dentin hypersensitivity with multiple gingival recessions in the upper anterior region....

OBJECTIVES To evaluate the effect of root canal sealers (RCS) and specimen aging on the bond strength of fibre posts to bovine intraradicular dentin. MATERIAL AND METHODS 80 teeth were used according the groups - Sealapextm, Sealer 26®, AH Plus® and specimens aging - test with no aging and with aging. The canals prepared were filled using one of each RCS. The posts were cemented. Roots were cr...

4'METAfMMA'TBB resin has shown good bieeompatibility and remarkable adhesion to dentin. It seems to be suitable for use {n periodontal tissues for retrograde root sealing and treatment of vertically fractured roots. For an adhesive resin to be useful clinically, it must bond not only to the dentin but also to the cementum. The purpose of this study was to evaluate the long-term adhesion durabil...

Introduction: A single incision palatal harvest technique was applied to minimize the size of the palatal wound and to allow for primary closure of the donor site, which may result in reduced postoperative discomfort. Aim: This case presentation describes the use of a coronally positioned flap with subepithelial connective tissue graft using a single incision technique for the treatment of dent...

BACKGROUND AND OBJECTIVES Smear layer removal with EDTA from root canal walls allows greater cleaning and disinfection of root canals. However, because Er:YAG laser acts on the removal of the smear layer, the objective of investigation was to analyze in vitro the effect of Er:YAG laser on dentin root canal wall permeability after endodontic instrumentation and irrigation with water or sodium hy...

Strengthening of Resilon-filled roots via an adhesive interface should be reflected by improvement in the interfacial strength and dislocation resistance between the root fillings and intraradicular dentin. This study compared the interfacial strengths of Resilon/Epiphany and gutta-percha/AH Plus using a thin-slice push-out test design. Failure modes of root slices after push-out testing were e...

The purpose of the review was to assess the effect of root canal irrigants on dentin bonding. A PubMed-based search was conducted on the articles published from 1980 to 2016. A brief overview and reviewing the effect on dentin bonding of common root canal irrigation solutions such as sodium hypochlorite (NaOCl), chlorhexidine (CHX), ethylenediaminetetraacetic acid (EDTA), mixture of a tetracycl...
