Abstract

Purpose: To evaluate and compare the effect of two enzymatic chemo-mechanical caries removal agents with conventional caries removal using rotatory instruments on the adhesion of composite resin to dentin of permanent teeth.

Methods: The sample comprised 30 permanent molars with caries lesions extending to the dentin, randomly distributed into three groups (n = 10 each): 1-Caries removal with rotary instruments (control group); 2-Caries removal with Papacárie Duo^® (F&A Laboratório Farmacêutico, São Paulo, Brazil); 3-Caries removal with Brix 3000™ (Brix S.R.L., Carcarañá, Argentina). After caries removal, the specimens were rinsed and dried. Scotchbond Universal™ adhesive (3 M, Saint Paul, Minnesota, USA) was actively applied in self-etch mode and light-cured. Resin composite increments were applied using a silicone mold (3 × 3 × 2 mm) and light-cured. Shear bond strength (MPa), work-to-debonding (J/m²), and shear modulus (kPa) were evaluated. For statistical analysis, the level of significance was set at 5%.

Results: The control group presented significantly higher shear bond strength values (8.50 ± 2.69 MPa) compared to the Brix 3000™ group (5.72 ± 1.55 MPa, p = 0.008). There were no significant differences between Papacárie Duo^® (6.66 ± 0.86 MPa) and the other groups (p > 0.05). Regarding work-to-debonding, the Papacárie Duo^® group had a significantly higher result (2944.41 ± 450.21 J/m²) than the Brix 3000™ group (1189.41 ± 504.13 J/m², p < 0.001) and the control group (967.10 ± 270.01 J/m², p < 0.001). Concerning shear modulus, the control group showed a significantly higher result (558.67 ± 168.96 kPa) than the Brix 3000™ group (339.79 ± 143.78 kPa, p = 0.008) and the Papacárie Duo^® group (223.04 ± 127.30 kPa, p < 0.001).

Conclusion: While the application of Papacárie Duo^® did not negatively affect composite resin adhesion to dentin of permanent teeth, the application of Brix 3000™ reduced adhesive forces, potentially limiting its clinical use. Further investigations are warranted to elucidate the effects of these materials on dentin substrate, particularly through clinical studies.

酶化学机械剂对复合树脂与恒牙牙本质粘附力的影响：体外研究。

目的：评估和比较两种酶化学机械除龋剂与使用旋转器械的传统除龋方法对复合树脂与恒牙牙本质粘附性的影响：样本包括 30 颗龋坏延伸至牙本质的恒磨牙，随机分为三组（每组 10 人）：1-用旋转器械去除龋齿（对照组）；2-用 Papacárie Duo® (F&A Laboratório Farmacêutico, São Paulo, Brazil) 去除龋齿；3-用 Brix 3000™ (Brix S.R.L., Carcarañá, Argentina) 去除龋齿。龋齿去除后，对样本进行冲洗和干燥。Scotchbond Universal™ 粘接剂（3 M，美国明尼苏达州圣保罗市）以自刻模式涂抹并光固化。使用硅胶模具（3 × 3 × 2 毫米）涂抹树脂复合增量并光固化。对剪切粘接强度（兆帕）、功-脱粘度（焦耳/平方米）和剪切模量（千帕）进行了评估。统计分析的显著性水平设定为 5%：对照组的剪切粘接强度值（8.50 ± 2.69 MPa）明显高于 Brix 3000™ 组（5.72 ± 1.55 MPa，p = 0.008）。Papacárie Duo® 组（6.66 ± 0.86 MPa）与其他组没有明显差异（p > 0.05）。在工作-脱粘方面，Papacárie Duo® 组的结果（2944.41 ± 450.21 J/m2）明显高于 Brix 3000™ 组（1189.41 ± 504.13 J/m2，p 2，p ® 组（223.04 ± 127.30 kPa，p 结论）：虽然使用 Papacárie Duo® 不会对复合树脂与恒牙牙本质的粘附力产生负面影响，但使用 Brix 3000™ 会降低粘附力，从而可能限制其临床使用。有必要进一步研究这些材料对牙本质基底的影响，特别是通过临床研究。

期刊介绍： The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
