Abstract
|
|
|
The ultimate goal of periodontal therapy is the regeneration of supporting tissues. It is recommended to avoid probing
until 6~9 months following the regenerative therapy because the probing may jeopardize the newly formed tissues. We can
measure tooth mobility objectively using Periotest. The purpose of this study is to investigate whether Periotest can be used to evaluate the treatment results alternatively, and whether there are the correlations between the changes of Periotest value (PTV) and other clinical parameters. Regenerative treatments have been performed on 29 teeth of twenty five patients, at Department of Periodontology, Pusan National University Hospital. We measured the tooth mobility by Periotest and other parameters at the baseline, 6 and 12 months after regenerative treatment. Compared to the baseline, there were the statistically significant improvements in all the parameters at 6 months and 12 months. There were statistically significant correlations among the probing depth, attachment level, gingival recession and PTV at baseline, 6 months, and 12 months. Also there was the correlation between changes in PTV and in the attachment level at each time of observation period. We may conclude that regenerative therapy would improve the clinical parameters and periodontal status and PTV would be an alternative index to evaluate the healing process after regenerative surgery.
