this study addresses the question of whether conservative methods of restoration may be applied efficaciously in permanent posterior teeth with proximal lesions and intact occlusal preventive resin restoration (prr). the purpose of the present study was to assess the microleakage at amalgam-composite interface and composite-composite interface in permanent tooth with prr.thirty-five premolar te...

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...

OBJECTIVE This study addresses the question of whether conservative methods of restoration may be applied efficaciously in permanent posterior teeth with proximal lesions and intact occlusal preventive resin restoration (PRR). The purpose of the present study was to assess the microleakage at amalgam-composite interface and composite-composite interface in permanent tooth with PRR. MATERIALS ...

The relationship between cavity preparation extension and restoration longevity is examined through a systemic review of the available evidence on specific conservative, operative caries-management strategies. Evidence tables are provided for three specific techniques in the permanent dentition: 1) the proximal "tunnel" restoration, 2) the proximal "box-only" restoration, and 3) the preventive ...

The purposes of this in vivo study were to determine if placing a sealant over a glass ionomer restoration modifies its fluoride release, and to examine the effect on glass ionomer of a 4-min application of topical fluoride. Fluoride release from glass ionomer preventive resin restorations placed in 21 bovine teeth was measured before and after removing their sealants. Fuji II, Ketac Silver, an...

Purpose: To compare in vitro fracture resistance of endodontically treated premolars restored with bonded amalgam or resin composite. Materials and Methods: Fifty intact and caries-free premolars that had been extracted for orthodontic treatment were selected. All teeth were subjected to endodontic procedures and MOD cavity preparation. They were then randomly divided into the five following gr...

conclusions estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. results the wear amounts of the composites are as follows in order: estelite sigma quick (1886.9 ± 518.5 μm2), estelite flow quick (2708.9 ± 578.1 μm2), estelite high flow (3206 ± 2...

Background and Aim: Restoration of primary anterior teeth with severe caries extending to the gingival margin is challenging for many clinicians especially in uncooperative children. Resin modified glass ionomer cements (RMGICs) can be suitable for use in such cases since they require fewer application steps than composite resins. This study aimed to assess the fracture strength of severely dam...

objectives: dental composite wear in posterior restorations is a concern and is affected by different factors. this study was conducted to evaluate the effect of polishing and mechanical loads on wear of silorane-based and methyl methacrylate-based composites resins. materials and methods: of each dental composite (filtek p90 and filtek p60), 40 samples were fabricated in a polyethylene mold (4...

Resin composites and adhesives are increasingly popular in dental restorations, but secondary caries is one of the main reasons for restoration failure. Quaternary ammonium monomers (QAMs) have an anti-microbial effect and are widely used in many fields. Since the concept of the immobilized antibacterial effect was put forward, dental restorations containing QAMs have been studied to reduce sec...
