The samples were divided into 4 groups according to the irrigation system used: Control or conventional needle (Group I), Navi Tip FX (Group II), EndoActivator (Group III), and EndoVac (Group IV).

An evaluation of effect of dentin pretreatment with various agents for varying time intervals on the shear bond strength of resin.

Background: This article highlights the contribution of collagen structure/stability to the bond strength. We hypothesize that induction of cross-linking in dentin collagen fibrils improves dentin collagen stability and thus bond strength with composite also improves.

Aims: The aim of the study was to evaluate the effect of collagen cross-linking agents on the shear bond strength of composite resins.

An Invitro Evaluation of Antimicrobial Efficacy and Flow Characteristics for AH Plus, MTA Fillapex, CRCS and Gutta Flow 2 Root Canal Sealer.

Introduction: Cleaning and shaping of root canal does not guarantee complete disinfection of the canal, regardless of the systems and techniques used for this purpose. Therefore, it becomes mandatory for the endodontic filling materials to have a good antimicrobial potential especially against E. faecalis.

Accidental aspiration/ingestion of foreign bodies in dentistry: A clinical and legal perspective.

The potential of foreign body aspiration or ingestion is a worldwide health problem in dentistry. The general dental practitioners should be extremely attentive in handling of minor instruments during any intervention related to the oral cavity, especially in the supine or semi-recumbent position of the patient. Aspiration cases are usually more critical and less common than ingestion.

Analysis of micro-shear bond strength of self-etch adhesive systems with dentine: An in vitro study.

Background: Success or failure of a composite restoration largely depends on its bonding to enamel/dentine. Several better adhesive systems have been developed during the last few years due to rapid advancement in the technology. Recent self-etched adhesives have fewer clinical steps and are less technique sensitive.
