Soft Drink Influence on Margin Integrity in Composite Resin Restorations

Effect of cavosurface margin configuration of Class V cavity preparations on microleakage of composite resin restorations.

AIM The aim of this study was to compare the marginal leakage of hybrid and microfilled composite resin in Class V restorations with and without an enamel bevel. METHODS AND MATERIALS Fifty-six cavities were prepared on the buccal and lingual surfaces of 28 extracted human molars using a round bur with the dimensions of 3 x 2 x 1.5 mm. The specimens were divided into two groups of 28 based on...

Effect of resealing on microleakage of resin composite restorations in relationship to margin design and composite type

OBJECTIVE To determine the relationship between margin preparation design and resin-composite type on microleakage with or without re-application of surface-penetrating sealant. METHODS Class-I resin-composite restorations were completed for 128 extracted human molars. Half of the margins were beveled, the other half, butt-joint. Half of each group was restored with Filtek-Supreme (FS), the o...

Effect of various grit burs on marginal integrity of resin composite restorations.

The purpose of this study was to evaluate the generation of enamel cracks and gaps at the cavosurface margin of resin composite restorations using various burs. Saucer-shaped cavities with a bevel were prepared on mid-coronal buccal or lingual surfaces of extracted human molars using a regular-grit round diamond bur, a fine-grit diamond bur, a superfine-grit diamond bur or a six-bladed tungsten...

Intraoral environment conditions and their influence on marginal leakage in composite resin restorations.

Color matching in the anterior superior incisor region (ASIR) is very difficult when using a rubber dam during restorative procedures. This study measured temperature/relative humidity parameters in the ASIR and evaluated the influence of the inhalation/downtime/exhalation mouth-breathing cycle on microleakage in composite resin restorations performed in the region, using three different adhesi...
