Abstract

Objectives. Indications of different dental restorations, direct or indirect composite restorations or amalgam, depend on clinical needs. Aim of this study is to compare margin sealing offered by three different restorative techniques. Materials and methods. 24 molars were selected and divided into three groups according to the technique used: group A (composite inlays), group B (direct composite restoration), group C (amalgam). First Class cavities having equal size were created by the same operator. All the samples were treated with ortho-phosphoric acid, adhesive system and composite flow. A cavity of each group was filled without etching and bonding before using the composite flow. After thermo-mechanical stress all samples underwent marginal leakage tests. Samples were sectioned and observed by optical stereomicroscope at various degree. Results and conclusions. Leakage was evident in those samples which were not submitted to etching and bonding; all remaining samples showed no leakage at all. Choice of restoration must consider operative time, operating field, aesthetic needs, cost and patient.
