Evaluation of the push-out bond strength (PBS) of glass fiber reinforced post (GFRP) bonded to root dentin after canal disinfection using food-based root canal irrigants i.e., Curcumin photosensitizer (CP), Riboflavin photosensitizer (RFP), Morinda ctrifolia juice (MCJ) and Sapindus mukorossi (SM) along with MTAD as a final irrigant.
Fifty human single-rooted premolar teeth were decoronated. Endodontic preparation was performed along with 2.25% sodium hypochlorite NaOCl solution followed by EDTA solution. Canals were dried and obturated followed by post-space preparation by removing GP. Specimens were allocated into five groups based on different food-based disinfection regimes (n = 10). Group 1: 2.25% NaOCl + MTAD (Control), Group 2: 6% MCJ + MTAD, Group 3: SM + MTAD, Group 4: CP + MTAD and Group 5: RFP + MTAD. All GFRP were bonded to radicular dentin. Root sectioning was performed followed by PBS and failure analysis using a universal testing machine (UTM) and stereomicroscope respectively. The data were analyzed using a one-way analysis of variance (ANOVA) test and the Post Hoc Tukey HSD test (p = 0.05).
Samples disinfected with(MCJ+MTAD) at coronal third demonstrated maximum PBS (9.41 ± 0.51 MPa). However, the apical third of group 5 (RFP + MTAD) exhibited the minimum values (4.06 ± 0.23 MPa). Intergroup comparison analysis unveiled that group 2 (MCJ +MTAD) and group 3 (SM+MTAD) displayed comparable outcomes of PBS at all three-thirds. Similarly, samples in group 1 (2.25% NaOCl + MTAD), group 4 (CP + MTAD), and group 5 (RFP + MTAD) exhibited comparable PBS.
Fruit-based irrigants Morinda citrifolia and Sapindus mukorossi have the potential to be used as root canal irrigants with a positive influence on bond strength.
评估使用基于食物的根管冲洗剂(姜黄素光敏剂[CP]、核黄素光敏剂[RFP]、余甘子汁[MCJ]和无患子[SM])对根管进行消毒后的玻璃纤维增强桩(GFRP)与根管牙本质的推出粘结强度(PBS),以及 MTAD 作为最终冲洗剂的作用。
将 50 个人类单根前磨牙进行去冠处理。根管预备时使用 2.25%次氯酸钠(NaOCl)溶液,随后使用 EDTA 溶液。根管干燥后用 GP 去除桩道,然后进行桩道预备。根据不同的基于食物的消毒方案将标本分为五组(n=10)。第 1 组:2.25% NaOCl+MTAD(对照组),第 2 组:6% MCJ+MTAD,第 3 组:SM+MTAD,第 4 组:CP+MTAD,第 5 组:RFP+MTAD。所有 GFRP 均粘结于根管牙本质。进行根段截取,然后使用万能试验机(UTM)进行 PBS 测试,使用立体显微镜进行失效分析。使用单向方差分析(ANOVA)检验和事后 Tukey HSD 检验(p=0.05)对数据进行分析。
用(MCJ+MTAD)消毒的样本在冠三分之一处表现出最大的 PBS(9.41±0.51 MPa)。然而,第 5 组(RFP+MTAD)的根尖三分之一处表现出最小的 PBS(4.06±0.23 MPa)。组间比较分析显示,第 2 组(MCJ+MTAD)和第 3 组(SM+MTAD)在所有三分之一处 PBS 结果相似。同样,第 1 组(2.25% NaOCl+MTAD)、第 4 组(CP+MTAD)和第 5 组(RFP+MTAD)的样本 PBS 结果也相似。
水果基冲洗剂余甘子和无患子具有作为根管冲洗剂的潜力,对粘结强度有积极影响。
