Abstract

BACKGROUND

This study aims to histologically evaluate the efficiency of debris removal through activation of 2.5% and 5.25% NaOCI using laser, ultrasonic, and intracanal heating methods.

METHODS

Sixty-four maxillary central incisor teeth were randomly divided into two groups according to the irrigation solution (n = 32); 2.5% NaOCI and 5.25% NaOCI. Subsequently, the samples were further divided into four subgroups according to the final irrigation activation technique (n = 8); SubgroupA: Er,Cs:YSGG laser, SubgroupB: Ultrasonic, Subgroup C: Intracanal heating, Subgroup D: no activation. Generalized Linear Models and Bonferroni tests were used for statistical analysis (p < 0.05).

RESULTS

The effect of NaOCI concentration was statistically significant (p < 0.001). Furthermore, the activation of NaOCI by laser exhibited a statistically significant difference compared to the ultrasonic and intracanal heating methods (p < 0.001).

CONCLUSION

The efficiency of root canal cleaning increases with higher NaOCI concentration. Activation of NaOCI also significantly enhances its effectiveness.

摘要

背景

本研究旨在通过激光、超声和根管内加热的方法，从组织学上评估激活 2.5%和 5.25%次氯酸钠（NaOCI）去除碎片的效率。

方法

将 64 颗上颌中切牙随机分为两组，根据冲洗液（n=32）分为 2.5%NaOCI 和 5.25%NaOCI。随后，根据最终冲洗激活技术将样本进一步分为四组（n=8）：A 组：Er，Cs：YSGG 激光，B 组：超声，C 组：根管内加热，D 组：无激活。采用广义线性模型和 Bonferroni 检验进行统计学分析（p<0.05）。
