Abstract:
The high level laser therapy (HLLT) treatment in dentistry
have been assured as a very successful method, but the low
level
laser
therapy
(LLLT)
is
still
limited
and
under
researches.
In this study a compare was done between the low level laser
therapy and chlorhexidine gel on treatment of gingivitis.
Forty eight patients were selected to be the cases of this
study.
In the left side chlorhexidine gel was applied after scaling and
polishing, and this group is called group A.
In the right side low level laser therapy was applied in
different doses after scaling and polishing, and this group is
called group B.
In group B1 5Hz, 0.15 mJ/cm2 per 5 minute of low level laser
therapy was applied to thirty one patients.
In group B2 50Hz, 1.5mJ/cm2 per 5 minute of low level laser
therapy was applied to twelve patients.
In group B3 1000Hz, 30mJ/cm2 per 5 minute of low level laser
therapy was applied to five patients.
using 5Hz accelerate the treatment of gingivitis faster than
using chlohexidine gel.
While using 50Hz is as effective as chlorhexidine on treatment
of gingivitis.
But using 1000Hz is a harmful application.
