Abstract

Objective: To evaluate the effect of 10% papain as an enamel deproteinising agent on the shear bond strength (SBS) of three orthodontic adhesives: Transbond XT, resin-modified glass ionomer cement (RMGIC) and Biofix.

Design: Single-centre, double-blinded, split-mouth randomised controlled trial.

Setting: Department of Orthodontics and Dentofacial Orthopaedics, Nair Hospital Dental College, Mumbai, India.

Participants: A total of 20 participants requiring bilateral premolar extraction for fixed orthodontic treatment in both the maxillary and mandibular arches were included in this study.

Methods: In total, 80 premolars from the above-mentioned participants were divided into four groups as follows: group A: Transbond XT deproteinised with 10% papain gel; group B: Biofix deproteinised with 10% papain gel; group C: RMGIC deproteinised with 10% papain gel; and group D: Transbond XT without enamel deproteinisation as a control group-bonded as instructed by the manufacturer. After deproteinisation, brackets were bonded and after a follow-up period of 28 days, the teeth were extracted. The SBS was then measured using the Universal Testing Machine. The force needed to shear the bracket was documented, and bond strengths were subsequently calculated in megapascals (MPa). The obtained results were subjected to statistical analysis and one-way ANOVA was performed to compare the mean SBS between the groups. Subsequently, pairwise comparisons were conducted using Tukey's post hoc test.

Results: There was a statistically significant difference in SBS among all groups (P = 0.002). The SBS of TransXT with deproteinisation increased significantly compared with TransXT without deproteinisation (P = 0.03). There was no statistically significant difference between the SBS of TransXT without deproteinisation and RMGIC (P = 0.47) and Biofix (P = 0.39), both with deproteinisation.

Conclusion: The use of 10% papain for deproteinising enamel improved the SBS of all materials. Deproteinising improved the SBS of RMGIC and Biofix to the level of TransXT without deproteinisation.

用 10%木瓜蛋白酶进行珐琅质脱蛋白处理是否会影响正畸粘合剂的剪切粘合强度:随机对照试验。
目的评估作为釉质脱蛋白剂的 10%木瓜蛋白酶对三种正畸粘合剂剪切粘接强度 (SBS) 的影响:设计:单中心、双盲、分口随机对照试验:地点:印度孟买奈尔医院牙科学院正畸与颌面矫形系:本研究共纳入了 20 名需要拔除双侧前磨牙以进行固定正畸治疗的上颌和下颌牙弓患者:方法:将上述参与者的 80 颗前磨牙分为以下四组:A 组:Transbond XT 用 10%的木瓜蛋白酶凝胶进行去蛋白处理;B 组:Biofix 用 10%的木瓜蛋白酶凝胶进行去蛋白处理;C 组:RMGIC 用 10%的木瓜蛋白酶凝胶进行去蛋白处理;D 组:Biofix 用 10%的木瓜蛋白酶凝胶进行去蛋白处理:用 10%木瓜蛋白酶凝胶对 RMGIC 进行去蛋白处理;以及 D 组:作为对照组,Transbond XT 未进行釉质脱蛋白处理,按照生产商的说明进行粘结。去蛋白后,粘结托槽,28 天后拔牙。然后使用万能试验机测量 SBS。剪切托槽所需的力被记录下来,随后以兆帕(MPa)为单位计算粘接强度。对所得结果进行统计分析,并通过单因素方差分析比较各组之间的平均 SBS。随后,使用 Tukey 后验法进行配对比较:所有组间的 SBS 差异均有统计学意义(P = 0.002)。与未去蛋白的 TransXT 相比,去蛋白的 TransXT 的 SBS 明显增加(P = 0.03)。未进行去蛋白处理的 TransXT 与进行了去蛋白处理的 RMGIC(P = 0.47)和 Biofix(P = 0.39)相比,其 SBS 没有明显的统计学差异:结论:使用10%木瓜蛋白酶对牙釉质进行去蛋白处理可改善所有材料的SBS。去蛋白可将 RMGIC 和 Biofix 的 SBS 提高到 TransXT 未去蛋白时的水平。

期刊介绍: The Journal of Orthodontics has an international circulation, publishing papers from throughout the world. The official journal of the British Orthodontic Society, it aims to publish high quality, evidence-based, clinically orientated or clinically relevant original research papers that will underpin evidence based orthodontic care. It particularly welcomes reports on prospective research into different treatment methods and techniques but also systematic reviews, meta-analyses and studies which will stimulate interest in new developments. Regular features include original papers on clinically relevant topics, clinical case reports, reviews of the orthodontic literature, editorials, book reviews, correspondence and other features of interest to the orthodontic community. The Journal is published in full colour throughout.
