The use of resin composite materials to restore the complete occlusion of worn teeth is controversial and data are scarce. In this case series, the authors report on seven cases of progressive mixed erosive/abrasive worn dentition (85 posterior teeth) that have been reconstructed with direct resin composite restorations. In all patients, either one or both tooth arches was completely restored u...

BACKGROUND AND AIM: Recurrent caries is defined as caries in the marginal edges of filled teeth and is the most common reason for restoration replacement. The aim of this study was to evaluation of recurrent caries in amalgam, resin-based restorations and crowns in bitewing radiographies in patients who attended Kerman dental radiology centers, Iran.METHODS: This cross-sectional study conducted...

PURPOSE To evaluate the clinical performance of direct Class II fiber-reinforced composite restorations on nonvital teeth. MATERIALS AND METHODS Thirty patients age 18 or older were included in this clinical trial restoring 35 molars. The inclusion criteria were: two- to four-surface restorations, replacement of composite and amalgam restorations necessary or unrestored teeth with decay reach...

AIM To evaluate the effect of dental bleaching with carbamide peroxide at different exposure times on the microleakage of resin composite and resin-modified glass ionomer restorations after placement in extracted human teeth. METHODS AND MATERIALS 120 Class V cavity preparations were placed at the cementoenamel junction (CEJ) of human teeth. Half of the cavities were restored with Filtek P60 ...

One of the critical goals of adhesive dentistry is to restore the peripheral seal of dentine that is interrupted when enamel is lost as a result of developmental sequelae, trauma, caries or operative intervention such as preparatory excision. For coronal lesions the exposed strata may be bounded by dentine, enamel or both. Manufacturers continue to work vigorously on resin formulations that wil...

OBJECTIVES In most retrospective studies, the clinical performance of restorations had not been considered in survival analysis. This study investigated the effect of including the clinically unacceptable cases according to modified United States Public Health Service (USPHS) criteria into the failed data on the survival analysis of direct restorations as to the longevity and prognostic variabl...

Objective. To assess fracture resistance and failure mode of repaired fiber-reinforced composite (FRC) cusp-replacing restorations. Methods. Sixteen extracted human premolars with fractured cusp-replacing woven (Group (A)) or unidirectional (Group (B)) FRC restorations from a previous loading experiment were repaired with resin composite and loaded to fracture. Results. Differences in fracture ...

Introduction Increased demand by patients and clinicians for esthetic restorations coupled with the public’s concern about mercury have resulted in an escalating use of resin composite materials (1). Resin composite is now often utilized to restore tooth surfaces previously accomplished with silver amalgam. Packable (a.k.a. moldable or condensable) resin composites are the product of vast amoun...

OBJECTIVES This randomized, split-mouth clinical study evaluated the survival rate of direct laminate veneers made of two resin-composite materials. METHODS A total of 23 patients (mean age: 52.4 years old) received 96 direct composite laminate veneers using two micro-hybrid composites in combination with two adhesive resins (Ena-Bond-Enamel HFO: n=48, Clearfil SE Bond-Miris2: n=48). Enamel w...
