Two composite resins (Ful-Fil ® and X-55®) were placed in the primary molars of 50 children aged 4 to 8 years. A total of 357 restorations were placed in 3 different cavity preparations. The restorations were evaluated by 2 investigators at 0, 6, 12, 24, and 36 months using the USPHS evaluation criteria. At 48 months 130 restorations were available for evaluation. This represents a recall rate ...

The aim of this in vitro study was performed to evaluate the effect of dentin bonding agents and glass ionomer cement beneath composite restorations and its resistance to fracture of endodontically treated teeth. Fifty sound extracted maxillary teeth were selected; ten of them for controls and the remainder were modified with root canal treatment and a mesial occlusal distal (MOD) cavity prepar...

Dental clinicians have an expanding range of biomaterial choices for restoring tooth structure. Scientific developments in cariology, advances in dental biomaterials, and patients' esthetic concerns have led to a reduction in amalgam restorations and an increase in composite restorations. The aim of this study was to compare teaching time with students' clinical procedures in amalgam and compos...

PURPOSE The aim of this study was to determine the static load-bearing capacity of endodontically treated maxillary incisors restored with post-core complex made of experimental fiber composite resin (FC) and complete crown made of particulate filler composite (PFC). Further aim was to evaluate the effect of FC resin on the failure mode of the restoration. MATERIAL AND METHODS The experimenta...

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...

Direct composite resin restoration of the patient with aesthetic problems in anterior teeth has been told. However, the patient's concerns that may occur after treatment have been handled. Different composite and restorative materials are used routinely in clinical practice. In particular, the restorations in the anterior region may cause the patients to worry. Many questions like those; "What ...

Ceramic full crowns can restore lost tooth structure, strength, and esthetics but remove about twice as much tooth as an onlay design. Onlay restorations can maintain facial enamel for long-term esthetics, preserve the dentogingival junction for optimum periodontal health, and use supragingival margins for predictable adhesive dentistry. Metallic onlays can create fracture strength 3 times that...

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...

Background and aims. Use of porcelain as inlays, laminates and metal-ceramic and all-ceramic crowns is common in modern dentistry. The high cost of ceramic restorations, time limitations and difficulty of removing these restorations result in delays in replacing fractured restorations; therefore, their repair is indicated. The aim of the present study was to compare the shear bond strengths of ...

BACKGROUND Limited information is available from randomized clinical trials comparing the longevity of amalgam and resin-based compomer/composite restorations. The authors compared replacement rates of these types of restorations in posterior teeth during the five-year follow-up of the New England Children's Amalgam Trial. METHODS The authors randomized children aged 6 to 10 years who had two...
