简要总结
Several techniques have been advocated to get good contacts in dental composite restorations including interdental separation ring. The investigators study focuses on using separation ring with circumferential matrix band instead of a sectional band. Moreover, the investigators have attempted to study proximal tightness and proximal contours of composite restoration as separate variables
详细描述
A total of 188 premolar teeth with proximal cavity to be assigned on alternate basis in two groups. Intervention group teeth received Automatrix band after cavity preparation followed by the separation ring using clamp while the control group received Automatrix band alone.
All teeth to be restored with P-60 composite restorative material(3M-ESPE Dental, USA). Outcome (proximal tightness) is determined by a blinded assessor just after the restoration.

入选标准
- •patients who had supra gingival Class II cavities in permanent premolars. Teeth with cavity isthmus less than one-third of intercuspal distance were inducted
排除标准
- •Partially erupted teeth, teeth with non-carious tooth surface wear or with orthodontic bands or brackets or whose adjacent tooth continuous with the cavity side is missing were excluded.
研究组 & 干预措施
automatrix band, Separation ring
The prepared teeth received Automatrix band (similar to the control group, product code# 62422513). The Automatrix was burnished against the adjacent tooth gently. Anatomical wedges were applied in the proximal area and then the separation ring (BiTine® round ring by Palodent systems, Dentsply International, DE, USA product # 659040) placed with the help of retainer forceps.

automatrix band
Teeth received Automatrix band alone (Wide-Regular type, dimensions 7.9 mm height and 0.05mm thickness, product code # 62422513). It was secured on the prepared tooth and burnished against the adjacent tooth gently. Anatomical wedges were placed in the inter-proximal area gingival to the cavity preparation.

结局指标
主要结局
proximal tightness
时间窗: 1 day (just after dental restoration)
The tightness of the proximal contact area resulting from either of the two matrix band system. It was measured using a nine inch long nylon dental floss (Johnson and Johnson, USA).
次要结局
- proximal contours(1 day (just after restoration placement))
