Aesthetic restoration of lost dental tissues of anterior teeth is a crucial challenge in restorative dentistry. Patients may suffer from undesirable esthetic problems due to color, shape, structural and position abnormalities of anterior teeth. Creating more conservative as well as more powerful restorations against occlusal, lateral and protrusive forces and emulating similar outlook to natura...

OBJECTIVE The aim of this study was to test the null hypothesis that different surface conditioning (etch and rinse and self-etch) and curing techniques (light cure/dual cure) had no effect on the shear bond strength of direct and indirect composite inlays. MATERIALS AND METHODS A total of 112 extracted human molar teeth were horizontally sectioned and randomly divided into two groups accordi...

Acid etching and filled acrylic materials have been generating great interest in the past few years because of increased public demand for esthetic restorations and alternatives to amalgam. Composite resin and ceramic inlays, which use adhesive bonding, were introduced to make possible toothcolored restorations. The physical properties of composite resin restorations, and their poor wear resist...

The plethora of ceramic systems available today for all types of indirect restorations can be confusing--and overwhelming--for the clinician. Having a better understanding of them is key. The authors use classification systems based on the microstructural components of ceramics and the processing techniques to help illustrate the various properties and uses.

Introduction: This in vitro study investigates the marginal and internal fit of indirect class II composite restorations. Two different processes for chair-side restorations were compared. In group A, the restorations were fabricated using CAD/CAM technology (Cerec, Sirona, Germany, Bernsheim) and in group B they were made by hand (GrandioSO Inlay System, VOCO GmbH, Germany, Cuxhaven). Methods:...

BACKGROUND Although composite restorations are really valuable for esthetic zones, they have shown less longevity rather than amalgam restorations. Since it may be related to the method used for curing the composite, postcuring could increase the degree of conversion and result in more long-lasting composite restorations. This study was planned to evaluate the effect of two different postcuring...

This study evaluated the influence of material combinations used in the resin coating technique (RCT) on the marginal adaptation of indirect restorations with gingival margins in enamel (EM) and cement (CM). Eighty third-molars were used. Two cavities were prepared in each tooth. The cavities were distributed into 16 groups. Cavities with EM were filled with the following material combinations:...

BACKGROUND Naïve-indirect comparisons are comparisons between competing clinical interventions' evidence from separate (uncontrolled) trials. Direct comparisons are comparisons within randomised control trials (RCTs). The objective of this empirical study is to test the null-hypothesis that trends and performance differences inferred from naïve-indirect comparisons and from direct comparisons/R...

STATEMENT OF PROBLEM Delayed dentin sealing is traditionally performed with indirect restorations. With this technique, dentin is sealed after the provisional phase at the cementation appointment. It was demonstrated that this chronology does not provide optimal conditions for bonding procedures. Immediate dentin sealing (IDS) is a new approach in which dentin is sealed immediately following to...

The clinical longevity of tooth-coloured restorations, whether direct or indirect, using composites and ceramics, greatly depends on the quality and stability of their marginal adaptation. In this issue, two interesting studies 7,15 bring this subject and lead us to an exciting discussion. Poor marginal adaptation of direct and indirect restorations exposes the dentin pulp complex to the oral e...
