背景:
本研究の目的は、2.5%および5.25%NaOCIusingレーザー、超音波、および管内加熱法を用いた活性化によるデブリ除去効率を組織学的に評価することである。
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.
方法:
64本の上顎中切歯(n=32)を2.5%NaOCIと5.25%NaOCIの2群に無作為に分けた。サブグループA:Er,Cs:YSGGlaser、サブグループB:超音波、サブグループC:管内加熱、サブグループD:活性化なし。統計解析には一般化線形モデルとボンフェローニ検定を用いた(p<0.05)。
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).
結果:
NaOCI濃度の影響は統計学的に有意であった(p<0.001)。さらに、NaOCIbylaserの活性化は、超音波および管内加熱法と比較して統計学的に有意な差を示した(p<0.001)。
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).
結論:
根管洗浄の効率はNaOCI濃度が高いほど向上する。また、NaOCIの活性化もその効果を有意に高める。
CONCLUSION: The efficiency of root canal cleaning increases with higher NaOCI concentration. Activation of NaOCI also significantly enhances its effectiveness.
