The Effect of Co2 Laser on Tricalcium Phosphate and• Hydroxyapatite when Used as an Apical Plug An Invitro Study
MOHAMED HASSAN EL-SABRy;
Abstract
An understanding of the; morphologic changes resulting from laser treatment of the tooth root surface is essential to define the clinical applications for lasers.
The purpose of this study were three folds the first part was construction of prefabricated apical plugs from a synthetic compound HA and TCP. Root length was divided into thirds; the plug length selected was the length of HA or TCP plugs which fill the apical one third of the prepared canal.
• The effects of C02 laser irradiation on apical dentin, plug materials were considered in the second part. Six discs, two of
each, with the following dimensions, 1 em. diameter and a thickness of 0.2 em were prepared from the respective putty, pressed and condensed in the prepared molds. Disc specimens were first calcined and then fired in the same manner performed in preparing the plugs.
In the third part: the effect of a standard wavelength of C02 laser beam at 2 and 5 seconds on HA and TCP apical plugs and the root dentin interface was evaluated at different magnifications by SEM.
The prepared 49 teeth plus the 6 fabricated discs from the tested materials (HA and TCP) were grouped as follows:
