The aim of this study is to evaluate the microleakage
resultant from; Silorane resin composite restorations in primary
teeth Prepared Using Burs And Er:YAG Laser with or without
using additional etching.
This study aimed to test the efficiency of debonding porcelain laminate veneers
(PLV) by using two application modes of Er:YAG laser (contact and non-contact mode),
and testing the change in dental pulp temperature for both application modes.

een extracted, non-carious human maxillary premolars, prepared for receiving
PLV, which fabricated of e.max and bonded by light cured resin cement. They divided into
two groups, each of them had 8 samples based on the application mode; group A with noncontact
mode, and group B with contact mode. Veneers of both groups debonded by the
same laser parameters (360mJ, 15Hz) during loading of a 20newton force on a specially
fabricated cervical margin of veneers. Debonding time and change of temperature was
recorded, then entered into SPSS V.19 and T-test for independent samples was applied.
All veneers were debonded, samples of non-contact mode group had much lower
debonding time (12.6 second) than contact mode samples (96.3 second), but with higher
change of temperature in non-contact (4.2 centigrade) than in contact mode (2.9
centigrade).p value was much less than 0.05%.
Within limits of this study, we can conclude that non-contact application mode was
more efficient in reducing debonding time than contact application mode at same laser
energy and frequency parameters, but with a higher change in pulp temperature.
The aim of this study is to evaluate the healing after
apicectomy by using two different techniques. And to evaluate the
effect of MTA as a retrograde filling material and also the Er:YAG
laser as a tool for resecting the apex, and the influence of them in
the healing.
Objective: To compare effect laser Er:Yag and polyacrylic acid on
microleakage of of resin-modified glass-ionomer cement.
Analysis of variance shows no statistical differences between
three groups .
The aim of the study is comparison of the efficiency of Er:YAG
Laser with Ultrasonic scaling in Chronic Periodontitis Treatment.
this study aimed to evaluate and compare enamel
cracks caused by removing of the adhesive remnant post debonding
of the fixed orthodontic appliance.
Many methods are used to treat Periodontitis such as scaling and root planing
(SRP) with hand instruments, Sonic and Ultrasonic instruments. Recently, lasers are used in periodontal.
The aim of the study is to compare the Efficiency of Er:YAG Laser
Combined with Scaling and Root
Planing in Chronic Periodontitis Treatment.
