When an esthetic restoration with minimal tooth reduction is desired, for example in patients with uncomplicated tooth fractures, composite partial coverage crowns may be a therapeutic option. The indirect composite restoration allows restoration of the original tooth anatomy, function, and esthetics to be reproduced while preserving tooth structure. The use of composite partial coverage crowns...

Objectives This study aimed to evaluate the retention of composite restorations of primary anterior teeth reinforced with composite posts, glass fber posts, para-pulpal pins with composite posts, and para-pulpal pins alone. Methods Forty freshly extracted sound primary canine teeth with at least two-third of the root length remaining were selected. After disinfection, the tooth crown was cut...

BACKGROUND Combined amalgam-composite restorations have been used through many years to benefit from the advantages of both dental amalgam and composite resin. Two variations have been mentioned for this technique, this study investigated the fracture resistance of maxillary premolar teeth with extended mesio-occluso-distal (MOD) cavities, restored with the two variations of combined amalgam-co...

background and aims. anterior esthetic restoration is challenging in pediatric dentistry, due to limited durability and poor retention of the restoration.this study assessed the effect of air abrasion on tensile failure load of composite class iii restorations using different preparation techniques. materials and methods. 100 extracted human anterior primary teeth were divided, based on the pre...

Direct adhesive composite restoration, a technique to restore tooth defects by bonding composite resin materials, has been widely used in the restoration of dental caries or other tooth defects. Retention of composite resin restoration mainly relies on bonding strength between the materials and dental tissue. The clinical outcomes rely greatly on the regulated clinical practice of dentists. In ...

OBJECTIVES To compare re-treatment choices for MOD amalgam or resin composite restorations with or without cusp fracture among dentists in Kuwait. METHODS A random sample of 158 dentists completed a questionnaire designed to obtain socio-demographic, educational and work-related information and their choices for re-treatment of four scenarios of failed restorations on lower first molars: 1. M...

Restoring posterior teeth with resin-based composite materials continues to gain popularity among clinicians, and the demand for such aesthetic restorations is increasing. Indeed, the most common aesthetic alternative to dental amalgam is resin composite. Moderate to large posterior composite restorations, however, have higher failure rates, more recurrent caries, and increased frequency of rep...
