Endodontic therapy requires meticulous root canal debridement, pathogen elimination, and effective obturation to prevent microbial intrusion. The presence of the smear layer hinders sealer penetration, compromising sealing effectiveness. Sodium hypochlorite and chlorhexidine are esteemed endodontic irrigants. Herbal extracts like neem and tulsi, with antimicrobial and anti-inflammatory properties, show promise for root canal irrigation. The study aimed to evaluate the efficacy of various irrigants in removing the smear layer and enhancing push-out bond strength at different root canal levels.
One hundred mandibular premolars with single canals were collected, and 50 samples each were used for the smear layer and push-out bond strength analysis. Neem and tulsi extracts were prepared for irrigation. Teeth were decoronated, and up to 30 (6%) canals were prepared and were randomly divided into five groups based on irrigants used. A smear layer examination was conducted after longitudinally sectioning the tooth and sections were observed in a scanning electron microscope (SEM). Obturation was done in the remaining samples, and the push-out bond strength was assessed using a universal test machine.
Sodium hypochlorite showed the highest smear layer removal efficacy followed by chlorhexidine, neem, tulsi leaves with rose water extract, and normal saline. Chlorhexidine exhibited the highest push-out bond strength, with the coronal third presenting the strongest values, followed by neem, tulsi with rose water, normal saline, and sodium hypochlorite.
The study underscores the potential of herbal irrigants in endodontic therapy, indicating promising results while emphasizing the necessity for further clinical trials to validate their efficacy and other properties.
根管治疗需要进行细致的根管清创、病原体清除以及有效的充填，以防止微生物侵入。玷污层的存在会阻碍封闭剂的渗透，从而降低封闭效果。次氯酸钠和氯己定是备受推崇的根管冲洗剂。印楝和罗勒等具有抗菌和抗炎特性的草药提取物在根管冲洗方面显示出应用前景。本研究旨在评估不同冲洗剂在去除玷污层以及提高不同根管水平的推出粘结强度方面的效果。
收集100颗单根管下颌前磨牙，将其中50个样本分别用于玷污层和推出粘结强度分析。制备了印楝和罗勒提取物用于冲洗。去除牙冠，预备多达30个（6%）根管，并根据所使用的冲洗剂随机分为五组。将牙齿纵向切片后进行玷污层检查，并在扫描电子显微镜（SEM）下观察切片。对其余样本进行充填，并使用万能试验机评估推出粘结强度。
次氯酸钠显示出最高的玷污层去除效果，其次是氯己定、印楝、玫瑰水提取物罗勒叶和生理盐水。氯己定表现出最高的推出粘结强度，冠部三分之一处的值最强，其次是印楝、玫瑰水罗勒、生理盐水和次氯酸钠。
该研究强调了草药冲洗剂在根管治疗中的潜力，表明了有前景的结果，同时强调有必要进行进一步的临床试验以验证其疗效和其他特性。
