A MAJOR part of dental practice is the treatment of localised lesions in teeth and the replacement of lost tissue with' restorative materials. As stated by Skinner and Phillips (1967), the lack of adhesion of most of them to the structure of the prepared tooth presents a serious problem; it causes seepage of deleterious agents along the interface between the restoration and the tooth (Nelscn et...

Introduction: Knowledge of the distribution of different malocclusions in a geographic location could help orthodontics better know the problems in that region. Moreover, giving awareness about the problem and treatment possibilities can help people. This study aimed to determine types of malocclusion and dental caries in children aged 11 to 14 years in Roudsar, Iran. Materials and Methods: In...

In epidemiological research the focus is on the occurrence, causes, and modifying factors of diseases and thereby their prevention. During the last decades, the epidemiology of dental caries has not dealt with the prevalence of the disease, but is measuring the past and present caries experience in terms of past and present treatment need, which does not follow the practices in epidemiology. Th...

Fluoride-releasing materials can be expected to inhibit secondary caries and enhance remineralization of decalcified dentin underneath restorations. The aim of this study was to evaluate the inhibitory effect on secondary caries and remineralization of decalcified dentin by fluoride-releasing adhesives. Two commercial fluoride-releasing adhesives, Reactmer bond (RB, Shofu) and One-up bond F (OB...

OBJECTIVE To estimate the prevalence of dental caries and treatment needs in 12-year-olds and adolescents. METHODS Cross-sectional study based on results from the epidemiological surveys: Oral Health Conditions in the State of Sao Paulo, 2002 and the Brazilian Oral Health Survey (SBBrasil) 2010. Secondary data for 5,782 (2002) and 369 (2010) 12-year-olds and 880 (2002) and 300 (2010) 15- to 1...

AIM Surveys on reasons for the placement and replacement of restorations have been conducted in various countries. The purpose of this paper is to bring together and review the data of 10 such surveys with similar methodology. METHOD The studies reviewed are all based on the protocol described by Mjör in 1981. RESULTS The surveys reviewed provide data on the reasons for the placement and re...

The objective of this in vitro study was to evaluate demineralization around restorations. Class V preparations were made on the buccal and lingual surfaces of each tooth. TPH (Group 1), Fuji II LC (Group 2), Tetric (Group 3), Dyract (Group 4), GS 80 (Group 5) and Chelon Fil (Group 6) were randomly placed in equal numbers of teeth. The teeth were submitted to a pH-cycling model associated with ...
