Marginal Integrity of Cervical Restorations with Caries-Affected Dentinal Walls: Effect of Contamination with Hemostatic Agents.

Objectives: The aim of this study was to compare the microleakage in normal and caries-affected dentin (CAD) and to investigate the effect of three hemostatic agents on the microleakage of Class V composite resin restorations in CAD.

Materials And Methods: Ninety-six Class V non-beveled cavities were prepared in 48 third molars at 1 mm below the cementoenamel junction (CEJ) in the cervical margin with the occlusogingival size of 2 mm, mesiodistal dimension of 3 mm, and a depth of 1.5 mm.

Composite resin bond strength to caries-affected dentin contaminated with 3 different hemostatic agents.

Bonding of composite resins to sound and caries-affected dentin in cervical areas may necessitate the use of hemostatic agents to control sulcular fluid and hemorrhage. The aim of this in vitro study was to evaluate the bond strengths of a self-etching adhesive system to sound and caries-affected dentin after the use of 3 different hemostatic agents. Composite resin cylinders were bonded to 48 caries-affected and 48 sound dentin surfaces in 8 groups.

Reviewing the parental standpoint about origin of the dental fear in children referred to dentistry centers of Isfahan University of Medical Sciences.

Background: Dental fear leads to lack of child cooperation. In general, without the patient's cooperation, success in remedy is impossible. This study aimed to evaluate parental view about the origins of the dental fear in children as well as their view about factors contributing to the prevention of child dental fear.
