Comparison of Effect of C-Factor on Bond Strength to Human Dentin Using Different Composite Resin Materials.

Background: The study was planned to assess the use of low shrinkage composites for restoring cavities with high configuration factor (C-factor) which are subjected to high stresses.

Aim: The aim of the study was to evaluate the effect of C- factor on tensile bond strength to human dentin using methacrylate based nanohybrid and low shrinkage silorane composite.

Materials And Methods: In this study 40 non carious human molar teeth were selected and assigned into two main groups - cavity (Class I cavity with high C-factor) and flat group (flat surface with low C-factor).

Effect of three different remineralizing agents on enamel caries formation--an in vitro study.

Background: Caries process is not a static one, but is dynamic with interspersed periods of demineralization and remineralization of enamel, intimately related and occurs episodically based upon the presence of cariogenic bacteria in dental plaque and the availability of refined carbohydrates for fermentation to organic acids.

Objectives: Early enamel caries could be reversed with avoidance of frank cavitation. The main objective of this study is to check wether enamel demineralization can be prevented by using the remineralizing agents.

Endodontic management of a maxillary first molar with unusual location of second mesio buccal orifice.

Maxillary first molar can have a mesio-buccal-2 (MB2) orifice located palatally, but adjacent to the mesio buccal orifice. An awareness and understanding of this root canal morphology can contribute to the successful outcome of root canal treatment. This report discusses endodontic treatment of a maxillary first molar with unusual location of second mesio buccal orifice.

Maxillary molar with two palatal roots: Two case reports.

An awareness and understanding of the presence of an additional root and unusual root canal morphology is essential as it determines the successful outcome of endodontic treatment. Aberrations in root canal anatomy are commonly occurring phenomena. A thorough knowledge of basic root canal anatomy and its variation is necessary for successful completion of endodontic treatment.
