The scientific literature has studies that assess the influence of erosive challenges with citric acidic drinks and substances on the adhesive bond strength to enamel and dentin, but does not contain information about the influence of regional components of an acidic diet on this process. Thus, this study evaluated the erosive influence of Amazonian tucupi on enamel and dentin microshear bond strength.
One hundred and sixty-eight healthy bovine incisors teeth were used, divided into 12 groups ( = 14). For erosive cycling, distilled water (negative control), cola-based soft drink (positive control), or tucupi were used, followed by adhesive strategies of (1) etch-and-rinse (conventional) (Adper™ Single Bond 2) and (2) self-etching (Clearfil SE Bond). All specimens were subjected to erosive cycling for 5 days and, after 24 h, composite resin cylinders were built up for the microshear bond strength test. The data showed normal distribution and were analyzed by two-way ANOVA, followed by the Tukey post and test ( ≤ 0.05).
There were no significant differences in enamel ( > 0.05). In dentin, only the groups exposed to cola-based soft drink showed significant differences ( < 0.01). The failure mode showed that Type II (mixed) was predominant (95%).
The erosive challenge with tucupi did not influence the bond strength to enamel and dentin, regardless of the adhesive strategy used.
科学文献中有关于评估柠檬酸饮料和物质的侵蚀性挑战对牙釉质和牙本质粘结强度影响的研究，但未包含酸性饮食的区域成分对该过程影响的信息。因此，本研究评估了亚马逊图皮汁对牙釉质和牙本质微剪切粘结强度的侵蚀性影响。
使用168颗健康牛切牙，分为12组（每组 = 14）。对于侵蚀循环，使用蒸馏水（阴性对照）、可乐型软饮料（阳性对照）或图皮汁，然后采用（1）酸蚀冲洗（传统方法）（Adper™ Single Bond 2）和（2）自酸蚀（Clearfil SE Bond）的粘结策略。所有标本进行5天的侵蚀循环，24小时后，构建复合树脂圆柱体进行微剪切粘结强度测试。数据呈正态分布，采用双向方差分析进行分析，随后进行Tukey事后检验（P≤0.05）。
牙釉质方面无显著差异（P>0.05）。在牙本质中，只有暴露于可乐型软饮料的组显示出显著差异（P<0.01）。失效模式显示II型（混合）占主导（95%）。
无论使用何种粘结策略，图皮汁的侵蚀性挑战均未影响对牙釉质和牙本质的粘结强度。
