Short-term Clinical Investigation of All-in-one Adhesive and Restorative System

Objective: Current trend of resin bonding is a one-bottle/one-step self-etching adhesive. A one-bottle/one-step resin bonding “Bond Force” was newly designed with fluoride-releasing property by Tokuyama Dental Corp. The purpose of this study was to examine a clinical performance of EsteliteΣ (Tokuyama Dental) composite restorations in combination with Bond Force up to 12 months after placement. Methods: Minimally-invasive ClassV and V-shape cervical cavities in permanent teeth were restored by 3 dentists from January 15 to Feburuary 28 in 2007. The prepared tooth were treated with Bond Force and filled with EsteliteΣ according to the manufacturer's instructions. The items of the evaluation were retention, marginal discoloration, marginal adaptation, surface texture, abrasion, marginal fracture, body fracture, secondary caries, spontaneous pain, cold water pain, hot water pain, occlusal pain, gingival irritation, and soft tissue irritation according to the Ryge's criteria. All the restorations were examined immediately after placement, at 6 and 12 months recalls. Results: A total of 39 restorations were placed in 39 patients (average age: 54.6, SD: 15.0). All the teeth restored were reported to be dentin cavities (shallow: 27, medium: 12) and vital at the time of placement of the restorations. Cold water pain in 3 cases, hot water pain in 2 cases, occlusal pain in 1 case were observed before preparation. Sensation during cutting were none in 36 cases and slight in 3 cases. All the restorations seemed to be clinically satisfactory in all aspects examined up to 12 months after placement. Conclusions: According to this clinical study, it has been demonstrated that Bond Force and EsteliteΣ was a satisfactory restorative system for the minimally-invasive ClassV and V-shape cervical cavities over a period of 12 months, and Kaplan-Meier statistics was 1.00.
