Daimi Dişlerde Farklı Adeziv Sistemler Kullanılarak Uygulanan Pit ve Fissür Örtücülerin Klinik Başarısının Değerlendirilmesi

Abstract

The aim of this in vivo study was to evaluate and compare the clinical success of a resin-based fissure sealant placed with prior application of etch-and-rinse (ER) and self-etch (SE) adhesives. 204 sealants were placed in 51 patients with previously unsealed and caries-free permanent first molars employing a split-mouth design. The teeth were randomized into four groups (n= 51 teeth/group) according to the adhesive system placed under the tested resin-based sealant (Delton FS+; Dentsply). Group 1 (Control arm): No bonding agent (conventional acid-etch sealant), Group 2: Prior enamel etch + ER adhesive (XP-Bond; Dentsply), Group 3: SE adhesive-only (Clearfil-SE-Bond; Kuraray) without prior etching, Group 4: Prior enamel etch + SE adhesive (Clearfil-SE-Bond). Clinical assessments were performed according to modified USPHS criteria at baseline and 1, 3, 6, 12, 18 months. At 18 months, the conventional technique and SE-only group had similar cumulative survival rates (62% and 45%, respectively) for occlusal surfaces. XP-Bond and Clearfil-SE-Bond with prior etching showed similar (90% and 94%, respectively) and higher survival rates. The cumulative survival rates on palatal/buccal surfaces showed similar outcomes as with occlusal surfaces: XP-Bond (94%), acid-etch + Clearfil-SE-Bond (96%), conventional sealant (54%) and Clearfil-SE-Bond-only (39%). The present results demonstrate that with prior enamel etching, the etch-and-rinse and self-etch groups showed similar and significiantly higher sealant retention rates compared to the conventional and self-etch-only bonded sealants. For the self-etch adhesive, prior enamel etching significantly increased sealant retention. The conventional technique outperformed the self-etch-only bonded sealants in the absence of statistical significance.
