BACKGROUND Failure of dental restorations is a major concern in dental practice. Replacement of failed restorations constitutes the majority of operative work. Clinicians should be aware of the longevity of, and likely reasons for the failure of, direct posterior restorations. In a long-term, randomized clinical trial, the authors compared the longevity of amalgam and composite. SUBJECTS, METHO...

T he superior physical properties of composite resins have aroused the possibility of their use beyond the accepted indications for acrylic resin and silicate cement. The literature has suggested the use of composite resin for Class I,‘m4 Class II,” and Class IV39 * restorations. Other reports advocated the use of composite resin or tested the influence of pins on the physical properties of com...

OBJECTIVE To investigate the survival rate over a 3-year period of posterior resin composite restorations placed by dental students of Kuwait University. MATERIALS AND METHODS Posterior resin composite restorations placed by 5th-, 6th- and 7th-year dental students between 2004 and 2005 were evaluated. All patients with posterior composite restorations placed during this period of time were re...

Early tooth-colored restorative materials were weak and only suitable for anterior teeth. Over time, composites were developed that offered improved properties enabling their use in posterior teeth where subject to occlusal loading and forces of mastication. Secondary caries is the main reason for failure of both amalgam and composite restorations. Amalgam restorations offer ease-of-use but poo...

PURPOSE To evaluate the 3-year clinical durability of the flowable bulk-fill resin composite SDR in Class I and Class II restorations. MATERIALS AND METHODS Thirty-eight pairs of Class I and 62 pairs of Class II restorations were placed in 44 male and 42 female patients (mean age 52.4 years). Each patient received at least two extended Class I or Class II restorations that were as similar as ...

Resin-based composites are an integral component of contemporary pediatric restorative dentistry. They can be utilized effectively for preventive resin restorations, moderate Class II restorations, Class III restorations, Class IV restorations, Class V restorations and strip crowns. Tooth isolation to prevent contamination is a critical factor, and high-risk children may not be ideal candidates...

This study was conducted in 533 children with 1,634 treated teeth who visited the Pediatric Dentistry Department at the Chiba Hospital of Tokyo Dental College between January and December, 2003. Restorations on deciduous tooth were categorized by age of patient and tooth type. The following observations were made: Children aged 4 (17.9%) visited the clinic most frequently and this group had the...

OBJECTIVE To determine the reasons for replacement of composite resin restorations and evaluate the association between the reasons for replacement of restorations with gender, duration of failure and different class of cavities. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Operative Department of Fatima Jinnah Dental Hospital, Karachi, from January to May 2009. METHODO...
