Abstract
The cavity preparation between the convent ion al methods and lasers were compared in 18 patients with 40 samples. • The patient acceptance was good with the laser procedures like that of the conventional methods. • The time required to prepare the cavity with laser was (6.50±1.63 minutes) slight longer than the conventional methods (4.65±0.93 minutes). • On the Scanning Electron Microscope analysis the surface of lased cavity was irregular in appearance with absence of smear layer. • The ground sect ions of the teeth in both methods showed no differences. • The histopathological study of the decalcified sect ions showed that there was no demonstrable pulpal hyperaemia and inflammation in both the methods. In conclusion, there were no significant difference s in the ground sect ion and decalcified sect ion with respect to laser and bur. • However with Scanning Electron Microscope there were significant surface changes between the groups with the laser showing a surface that is beneficial for adhesive restoration and features which suggest that they could reduce the post operative hypersensitivity.
