摘要/Abstract

摘要： 目的: 比较Garrison Composi-Tight与Palodent V3两种成形系统行后牙Ⅱ类洞复合树脂直接充填的效果,量化窝洞邻面关键点与邻牙距离对充填质量的影响。方法: 采用非随机研究设计,纳入就诊于天津医科大学口腔医院牙体牙髓科的后牙Ⅱ类洞龋病病例 70 例,根据窝洞特征在治疗中选择不同的成形系统:Garrison组(n=38)和Palodent组(n=32)。窝洞预备后,测量窝洞邻面5个关键点与邻牙的距离(龈壁中央点A、龈壁颊/舌转角点B1/B2、牙合面颊/舌洞缘点C1/C2)。充填完成30 min后拍摄X线片,采用FDI(World Dental Federation,FDI Criteria)和改良USPHS标准(United States Public Health Service,USPHS Criteria)评估后牙Ⅱ类洞直接充填效果,并进行统计学分析。结果: Garrison组的放射检查评分中位值为1.000显著低于Palodent组的2.000(z=-3.354,P=0.001)。Palodent组的解剖外形评分中位值为1.000,低于Garrison组的2.000(z=-2.694,P=0.007)。树脂溢出与5个位点距离呈显著负相关(P<0.05);边缘适应性与5个位点的距离呈显著正相关(P<0.05)。修复体微裂与龈壁点(A, B1, B2)的距离呈负相关(P<0.05)。结论: 窝洞邻面与邻牙的距离控制在0.69~0.87 mm区间内两种邻面成型系统较易获得理想的充填效果。

Abstract: Objective: To compare the clinical performance of the Garrison Composi-Tight and Palodent V3 matrix systems in direct composite resin restorations for posterior Class Ⅱ cavities and to quantify the impact of the distance between key points on the proximal cavity surface and the adjacent tooth on the restoration quality. Methods: The study included 70 cases of posterior Class Ⅱ carious cavities treated in the Department of Operative Dentistry and Endodontics at Tianjin Medical University School of Stomatology. The matrix system was selected based on predefined cavity characteristics (Garrison group: n=38; Palodent group: n=32). The distances from five key points on the proximal cavity surface to the adjacent tooth were measured: the center of the gingival wall (A), the buccal/lingual gingival embrasures (B1/B2), and the buccal/lingual cavosurface margins at the occlusal aspect (C1/C2). Radiographs were taken 30 minutes post-restoration. The restoration quality was evaluated using the FDI criteria and modified USPHS criteria, followed by statistical analysis. Results: The Garrison group demonstrated a significantly superior radiographic evaluation score (median=1.000) compared to the Palodent group (median=2.000) (z=-3.354, P=0.001). Conversely, the Palodent group showed a better anatomical form score (median=1.000) than the Garrison group (median=2.000) (z=-2.694, P=0.007). A significant negative correlation was observed between resin flash and the distance at all five measurement points (P<0.05), while a significant positive correlation was found between marginal adaptation and the distance at all five points (P<0.05), with identified cut-off values for both. Restoration microleakage showed a negative correlation with the distance at the gingival wall points (A, B1, B2) (P<0.05). Conclusion: The distance between the proximal cavity surface and the adjacent tooth within the range of 0.69-0.87 mm facilitates the achievement of an ideal restoration outcome.
