目的:
本研究の目的は、バイオセラミックシーラーとエポキシレジン系シーラーを混合し、顎骨三半規管への浸透性と適合性を比較・検討することである。
OBJECTIVE: The aim of this study was to compare and evaluate the dentinal tubule penetration and adaptation of a premixed bioceramic sealer and an epoxy-resin based sealer in the three radicular thirds.
方法:
根管充填に使用したシーラーによって2つのグループ(n=14)に分けられた30本の広い根(単一直管と完全形成尖端)を歯内療法で準備した。根管充填に使用したシーラーによって2群(n=14)に分けた:AH-Plus(AHP)とBio-Cシーラー(BIOC).2サンプルはコントロールとして残した。根管充填後、サンプルを切断し、走査型電子顕微鏡で画像を撮影して観察し、シーラーの管内浸透性と適合性を分析しました。結果は、Shapiro Wilk、Levene、Mann-Whitney検定で統計的に分析された(P<0.05)。
METHODS: 30 wide roots, with single straight canals and totally formed apexes, were endodontically prepared and divided into two groups (n=14) according to the sealer used for root canal filling: AH-Plus (AHP) and Bio-C Sealer (BIOC). Two samples were left as controls. After the canals were filled, the samples were cut and viewed under Scanning Electron Microscopy by taking images to analyse the tubular penetration and adaptation of the sealers. The results were statistically analysed with the Shapiro Wilk, Levene and Mann-Whitney tests (P<0.05).
結果:
BIOCはAHPに比べ,根管内への浸透性が高く(P<0.05),根管壁への馴染みも良好であった.
RESULTS: BIOC showed significantly higher penetration in dentinal tubules than AHP in the cervical, middle and apical thirds of the root canal (P<0.05) and better adaptation to the dentinal tubule walls.
結論:
BIOCは,AHPと比較して,根管内への浸透性が高く,歯質への適合性も良好であった.
CONCLUSION: Under the parameters of this study, BIOC exhibits higher penetration and better adaptation to the dentinal tubules compared to AHP.
