초록
치주치료의 궁극적 목표는 치주질환으로 상실된 치주조직의 재생이라고 볼 수 있다. 치주재생술식 후 회복을 평가하는 단계에서, 탐침과정이 초기 회복기의 신생조직에 위해한 영향을 줄 수 있다. 치아동요도는 치주조직이 치아를 지지하고 있는 상태를 평가하는 중요한 지표로 사용된다. 이에 본 연구에서는 치아동요도와 다른 임상지표간의 상관관계를 조사하고, 치아동요도를 측정하는 PeriotestⓇ가 재생술식 후 초기 회복기에 탐침의 필요성을 배제할 수 있는지를 조사하고자 하는 것이다. 치주재생수술을 받은 25명의 환자, 29개의 치아를 대상으로 하였다. 부착수준, 치주낭 심도, 치아동요도 (PeriotestⓇ value PTV)등의 임상지표를 연구시작단계, 시술 후 6개월, 12개월에 측정하였다. 재생수술 후 모든 임상지표들이 개선되었고 (p<0.05), 각각의 시기에 부착수준, 탐침깊이, 치은퇴축과 PTV 사이의 통계적으로 유의한 상관관계가 관찰되었다. 또한 각 시기 사이의 임상지표와 PTV변화량의 상관관계에서 치주낭깊이와 부착수준이 상관관계가 있는 것으로 관찰되었다. 이상의 결과들로 치주재생술식 이후 임상지표들의 개선을 기대할 수 있으며, 재생술식 이후 회복기에 임상지표의 측정에 PTV가 보조적 역할을 할 수 있을 것으로 사료된다.
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.
