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.
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 this study was to compare the effects of
gingivectomy by using traditional surgery procedure and Er:YaG
laser depending on the following clinical indications: the pain
after 2 hours and 24 hours of surgery procedure, healing of
gum aft
er surgery depending on rosiness and polypus
indications after removing periodontal dressing and gingival
bleeding during and after surgery.
furcation involvement occurs in the term of chronic periodontitis, and gives the
involved tooth worse prognosis, so that it represents a problem for diagnosis and treatment. The aim of
this study was to compare clinically the surgical treatment of
second degree- furcal involvement in
mandiblur molars (that each of them has one furcation), using Er:YAG laser versus conventional surgery.
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.
