Abstract
The purpose of this study was to evaluate the effect of laser on the permeability of gingival crevicular epithelium or periodontal pocket epithelium. For this reserch, 50 patients(18 men and 32 women : 25 to 53 years old) were selected.
The right upper lateral incisors irradiated with laser were used as the irradiated group, and non-irradiated left upper lateral incisors were used as control group.
The amount of gingival crevicular fluid was measured by Periotron(r) (Harco-600, Canada ) weekly from initial examination until 2-week later. Papillary bleeding index(Saxer &Mu-hlemann) was measured by Michigan-O probe at the mesial and distal
surface
of each interdental papilla. Laser (semiconductive laser:DENS-BIO LASER(r)) was irradiated on periodontal pocket base of the tooth of lased group by means of periodontal treatment dosage (6,000Hz, 14mw, pulse laser, 3minutes, once).
The change of gingival crevicular fluid flow to laser irradiation was statistically analyzed by SAS (statistical analysis system) using ANOVA and Duncan’s multiple comparison.
@ES The results were as follows:
@EN 1. The amount of gingival crevicular fluid flow was significantly increased according to papillary bleeding index at initial examination in the lased group(P<0.05).
2. The amount of gingival crevicular fluid flow between the first laser-exposure 1-week after and the second was significantly decreased in papillary index 3, and that between initial examination and the first laser-exposure 1-week after and the
second
was significantly decreased in papillary bleeding index 4, in the lased group, respectively (P<0.05).
3. The amount of gingival crevicular fluid flow was significantly increased according to papillary bleeding index of initial examination(P<0.05), and was significantly decreased at two-week after in papillary bleeding index 3 in the non-lased
group(P<0.05).
4. The change of the amount of gingival crevicular fluid flow between the control group and the second laser-exposure 1-week after in the lased group was significant in papillary bleeding index 3 in comparison with the lased and the non-lased
group(P<0.05).
5. The change of the amount of gingival crevicular fluid flow between the control group and the first and second laser-exposure 1-week after in the lased group was significant in papillary bleeding index 4 in comparison with the lased and the
non-lased
group(P<0.05).
