| description | Micronucleus is one of early markers of DNA damage due to panoramic
radiography radiation exposure which might be related to carcinogenesis
mechanism. The DNA damage occured because of oxidative reaction that can be
detected using 8-oxo-dG expression. β-Carotene is lipid soluble antioxidant
substance which is expected to prevent the oxidative reaction and to improve the
juctional communication which detected by Cx-43. The objectives of this study
were to prepare and to develop topical β-Carotene in order to prevent
micronucleus formation on the gingival mucosa due to panoramic radiography
exposure.
The preparation of β-Carotene gingival mucoadhesive patch were done after
analizing the β-Carotene capability to penetrate gingival mucosa. β-Carotene
gingival mucoadhesive patch had been applied to gingival mucosa on the
experimental rabbits. In Group I, the rabbits weren�t applied with the patch.
Group II were applied before, Group III just in the time and Group IV after
panoramic radiography exposure. Micronucleus samples were taken from the
swabbed of rabbit�s gingival mucosa then stained by using modified Feulgen-
Rossenbeck. The 8-oxo-dG and Cx-43 expression were detected using
immunohistochemistry technique. The results were analyzed using descriptive
quantitative analysis, paired t-test, two way anova and Pearson correlation.
β-Carotene gingival mucoadhesif patch could be formed and the β-Carotene
substances would be transported into rabbit�s gingival mucosa.The increasing
number of micronucleus from Group I had different mean (p<0.05) with Group III
and IV. There were significant influences (p<0.05) of β-Carotene gingival
mucoadhesif patch application on Group II and III. It proved that the application
of β-Carotene gingival mucoadhesive prevented the increasing number of
micronucleus especially when it was applied before and during panoramic
radiograpy exposure. In conclusion, the β-Carotene gingival mucoadhesive patch
can be utilized to prevent the panoramic radiography radiation exposure on
rabbit�s gingival mucosa. |
