摘要

目的：评价不同的牙本质水分条件对不同种类根管封闭剂润湿作用的影响，即生物陶瓷基封闭剂-Smart Paste Bio、树脂基封闭器-AH-Plus和氧化锌丁香酚基封闭物-Tubliseal。材料与方法：本研究采用随机抽样法进行体外比较研究。通过对27颗新鲜提取的单根下颌第一前磨牙进行纵向切片，共制备了54个牙本质样品。然后将54个样品根据所使用的密封剂分为三组，每组18个。用5.25%的次氯酸钠冲洗牙本质样品，然后用17%的EDTA冲洗，最后用蒸馏水冲洗。18根据干燥、潮湿和潮湿条件下的各种牙本质水分条件，将每个密封组的样品进一步分为六个单独的亚组。在平坦的牙本质表面沉积0.1ml密封剂，并测量接触角。在95%置信区间下，使用方差分析和Post-hoc Tukey检验进行统计评估，P值<0.05被认为具有统计学意义。结果：采用单因素方差分析法分析了三种不同密封剂在不同水分条件下润湿能力的统计学显著性差异，P值<0.001，具有统计学显著性。采用事后Tukeys检验分析了两组在干燥、潮湿和潮湿条件下的接触角，P值=0.001，<0.05，因此所有亚组之间存在统计学显著差异。结论：在本体外研究的范围内，可以得出结论，在干燥和潮湿的牙本质条件下，树脂基密封剂-AH-Plus的润湿行为明显优于生物陶瓷密封剂-Smart Paste Bio和氧化锌丁香酚密封剂-Tubliseal。

Influence of dentin moisture conditions on the wetting action of different endodontic sealers using Rame-Hart goniometer: An in vitro study

Aim: To evaluate the influence of different dentin moisture conditions on the wetting action of different classes of endodontic sealers, that is, Bioceramic based sealer – Smart Paste Bio, Resin based sealer - AH Plus and Zinc oxide eugenol based sealer – Tubliseal. Materials and Methods: The present research is an in vitro comparative study in which the samples were selected by random sample method. A total of 54 dentin samples were prepared by longitudinally sectioning 27 freshly extracted single rooted mandibular first premolars. 54 samples were then allocated into three groups of 18 each based on the sealer used. Irrigation of the dentin samples were done with 5.25% sodium hypochlorite followed by 17% EDTA and a final rinse with distilled water.18 samples in each sealer group were further divided into separate subgroups of six each on the wide variety of dentin moisture conditions subjected to dry, moist and wet conditions. 0.1ml of sealer was deposited on flat dentin surface and contact angles were measured. Statistical evaluation was done using Analysis of variance and Post-hoc Tukey test at 95% confidence interval and P value <0.05 was considered statistical significant. Results: One way ANOVA was done to analyse the statistical significant difference between the wetting ability of three different sealers under different moisture condition the P Value was <0.001 which was considered statistically significant. Post hoc Tukeys test was done to analyze the contact angle between the two groups in dry, moist and wet condition with P value =0.001 which is <0.05 hence there is a statistical significant difference among all the subgroups. Conclusion: Within the limitation of this in vitro study it can be concluded that the wetting behavior of Resin based sealer - AH Plus was significantly better than Bioceramic sealer - Smart Paste Bio and Zinc oxide eugenol sealer - Tubliseal during dry and moist dentin conditions.

期刊介绍： It is a journal aimed for research, scientific facts and details covering all specialties of dentistry with a good determination for exploring and sharing the knowledge in the medical and dental fraternity. The scope is therefore huge covering almost all streams of dentistry - starting from original studies, systematic reviews, narrative reviews, very unique case reports. Our journal appreciates research articles pertaining with advancement of dentistry. Journal scope is not limited to these subjects and is more wider covering all specialities of dentistry follows: Preventive and Community Dentistry (Dental Public Health) Endodontics Oral and Maxillofacial Pathology Oral and Maxillofacial Radiology Oral and Maxillofacial Surgery (also called Oral Surgery) Orthodontics and Dentofacial Orthopaedics Periodontology (also called Periodontics) Pediatric Dentistry (also called Pedodontics) Prosthodontics (also called Prosthetic Dentistry) Oral Medicine Special Needs Dentistry (also called Special Care Dentistry) Oral Biology Forensic Odontology Geriatric Dentistry or Geriodontics Implantology Laser and Aesthetic Dentistry.
