A randomized double-blind clinical trial of posterior composite restorations with or without bevel: 1-year follow-up.

Objective: This randomized double-blind clinical trial compared the performance of posterior composite restorations with or without bevel, after 1-year follow-up.

Material And Methods: Thirteen volunteers requiring at least two posterior composite restorations were selected. Twenty-nine cavities were performed, comprising 14 without bevel (butt joint) and 15 with bevel preparation of the enamel cavosurface angle.

Double-blind randomized clinical trial of posterior composite restorations with or without bevel: 6-month follow-up.

Aim: This double-blind randomized clinical trial compared the performance of posterior composite restorations with and without bevel.

Methods And Materials: Thirteen volunteers requiring at least two posterior Class II restorations were selected. Twenty-nine cavity preparations were performed, comprising 14 without bevel (butt joint) and 15 with marginal beveling.
