The purpose of this study was to evaluate clinically and histopathologically the effects
to the periodontal tissue in rats after Cyclosporin A (CsA) administration and to
determine whether there is a relationship between dosage of CsA or blood CsA level
and the seventy of gingival overgrowth in rats.
Twenty 6-week-old Sprauge-Dawley Fats were randomized into 4groups. The control
group received olive oil only and the test group received daily CsA in olive oil via
gastric feeding for 6weeks at a 3,10, and 30§·/§¸. Rats were weighed to evaluate the
systemic effect of drug and stone models were made from alginate impressions of upper
and lover anterior region at 2 week interval.
On completion of offal CsA administration, blood were collected and blood CsA levels
were quantitated by TDxFLx analyzer. Rats were sacrificed an6 their upper and lower
jaws were removed together with the surrounding gingiva and soft tissue for light
microscopic examination.
The results were as follows :
1. The weight gain of GsA-treated rats was much less than of the control group and
central incisors were gradually displaced and separated in the test groups.
2. The extensive fibrovascular proliferation and scattered inflammatoy infiltrates in an
edematous stroma were observed in enlarged gingiva of CsA-treated rats.
3. The increase in buccolingual, mesiodistal dimension of the anterior teeth and
vertical height of the interdental papilla showed dose-dependent manner in CsA-treated
rats.
4. Significant positive correlation exists between blood CsA level and the severity of
gingival overgrowth in anterior teeth.
This result indicates that the severity of gingival enlargement in CsA treated rats is
correlated with dosage of CsA administration and blood CsA level.
