摘要

目的临床评估旋转式(ProTaper Next [PTN])和往复式(Wave One Gold [WOG])器械技术在单次根管治疗中消除根尖牙周炎患者根管内细菌的效果:40 名患者被随机分配到 WOG 或 PTN 器械技术组。所有患者均接受了单次根管治疗。两组患者均使用 10 毫升次氯酸钠(NaOCl)冲洗根管,并采用最终冲洗方案。分别在最初(样本 1)、化学机械器械治疗后(样本 2)和最终灌洗方案后(样本 3)采集根管微生物样本。使用培养法(菌落形成单位 [CFUs])对根管治疗各阶段的细菌进行定量,并使用 MALDI-TOF 质谱鉴定细菌种类:结果:共鉴定出 55 种需氧和厌氧细菌。采用两种器械技术和最终冲洗方案进行化学机械根管治疗可显著减少 CFU 的数量(P0.05):结论:尽管两种根管器械技术在清除慢性根尖牙周炎坏死牙管中的细菌方面都非常有效,但在任何样本中都没有发现完全根除的细菌。

Antibacterial Efficacy of Rotary and Reciprocating Instrumentation Techniques.

Objectives: To clinically evaluate the effectiveness of rotary (ProTaper Next [PTN]) and reciprocating (Wave One Gold [WOG]) instrumentation techniques in eliminating bacteria from the root canals of teeth with apical periodontitis during a single-visit root canal treatment.

Materials and methods: Forty patients were randomly assigned to the WOG or PTN instrumentation techniques groups. A single-visit root canal treatment was performed on all the patients. In both groups, root canals were irrigated with 10 ml of sodium hypochlorite (NaOCl) and the final irrigation protocol was applied. Microbiological samples from the root canal were collected initially (Sample 1), after chemo-mechanical instrumentation (Sample 2), and after the final irrigation protocol (Sample 3). Quantification of bacteria at each stage of root canal treatment was performed using the culture method (colony-forming units [CFUs]), and bacterial species were identified using MALDI-TOF mass spectrometry.

Results: There were 55 aerobic and anaerobic bacterial species identified. Chemo-mechanical root canal treatment with both instrumentation techniques and the final irrigation protocol significantly reduced the number of CFUs (p<0.001). There were no statistically significant differences in antibacterial efficacy between WOG and PTN groups (p>0.05).

Conclusion: Although both root canal instrumentation techniques were highly effective in removing bacteria from the necrotic canals of teeth with chronic apical periodontitis, no complete eradication of bacteria was found in any sample.
