Conventionally the extensive occlusal lesion is dealt with the removal of caries as well as undermined enamel. Various studies have shown that composite has the ability to bind the tooth structure at the same time, it reinforces the walls of the cavity. In the present study 225 teeth were taken, out of which, in 75 teeth conventional class I cavity was prepared (control). In rest of the samples after preparation of conventional class I cavity dentin below the enamel was removed, thus simulating the common clinical situation in such teeth. The undermined area was reinforced with hybrid composite and the rest of the cavity was restored with three types of filling material, amalgam, amalgam & composite and only composite. The fracture resistance was tested. The study proves the reinforcing property of composites and thus clinical feasibility of the technique in such teeth. |
