Abstract

|
|
The ultimate goal of periodontal therapy is promoting the regeneration of lst periodontal tissue. The purpose of this study is to compare the effect of treatment using expanded polytetrafluoroethylene (e-PTFE) as a barrier membrane in conjunction
with
porous resorbable calcium carbonate as a bone graft material. 71 infrabony defects from 54 patients with clinical diagnosis of chronic periodontitis were selected among those 20 defects were treated via flap operation only and designated as the
control
group, another 20 defects were treated with e-PTFE barrier membrane covering via flap operation and designated as the experimental group I, 16 defects were treated with e-PTFE barrier membrane covering and porous resorbable calcium carbonate
grafting,
and designated as the experimental group II, 15 defects were treated with porous resorbable calcium carbonate grafting via flap operation. Clinical parameters including probing depth, loss of attachment, probing bone level and gingival recession
have
been recorded at 6th months, and the significance of the changes has been analyzed. Correlation coefficients among these clinical parameters were analyzed.
@ES The results are as follows:
@EN 1.Probing depth were reduced with statistically significance(p<0.1). Experimental group I(p<0.01) and experiemtnal group II (p<0.05) showed statistically significant higher decrease compared to the control group.
2. Lose of attachment showed statistically significant decrease in both control and experimental group I, II, III, (p<0.01) and experimental group I and II showed statistically higher decrease compared to the control group. (p<0.01)
3. Probing bone level showed insignificant decrease in the control group, but experimental group I, II, III showed statistically significant decrease. (p<0.01)
4. Gingival recession showed statistically significant increase in the control group and experimental group I, III(p<0.01), but no statistically significant increase in experimental group II.
5. Comparisons among the experimental groups showed no statistically significant changes in all parameters.
6. Correlations among the changes of probing depth and loss of attachment to the initial probing depth showed statistically significant in all groups(p<0.05), and the clinical parameters showed statistical significance between probing depth and
loss of
attachment (p<0.05), and between loss of attachment and probing bone level in all group.(p<0.05)
On the bases of these results, treatments using expanded polytetrafluoroethylene(e-PTEF) membrane promote changes on probing depth and loss of attachment in infrabony defects, and using e-PTFE membrane, bone graft material, and e-PTFE membrane in
conjunction with bone graft material changes on probing bone level is promoted.
Therefore using e-PTFE membrane increases the efficiency on therapeutic effects for periodontal regeneration.
