摘要
目的:比较旋转式和往复式根管成形系统对模拟根管成形的影响。方法:将90个模拟根管树脂块分为6组(每组15个);三组仪器被分配给本科生和三组牙髓学专家。对于每种类型的经验,都使用Protaper Gold™,Wave One Gold™和不锈钢K-File (Control)进行整形。树脂块上墨,取仪前和仪后摄影图像,用成像软件(GIMP 2.10.10)进行叠加,用ImageJ软件进行分析。每台仪器使用后,用2.5%的NaOCl冲洗。评估的结果是是否存在根尖压缩、边缘、穿孔、定心能力和去除的树脂量。结果:树脂块的摄影分析显示,在大学生群体中普遍存在根尖拉链;专家组实现的壁架数量较多,而非专家组的穿孔数量较多。大学生WOG组树脂去除量显著增加,定心能力显著提高。结论:旋转往复系统提供了有效的操作标准;顺便说一下,不专业的操作员在管理往复系统方面表现出很大的困难。需要更多的研究来评估这一参数。
Influence of operator’s experience in three different instrumentation techniques: an in vitro study
Aim: To evaluate the influence of operator’s experience comparing rotary and reciprocating shaping systems on simulated root canals.
Methodology: Ninety resin blocks with simulated root canals were distributed to six groups (15 for each group); three groups of instrumentation were assigned to undergraduate students and three to specialists in endodontics. For each category of experience, the shaping was performed with Protaper Gold™, Wave One Gold™ and Stainless-steel K-File (Control). Resin blocks were inked, then pre- and post-instrumentation photographic images were taken to be superimposed by an imaging software (GIMP 2.10.10) and analyzed by ImageJ software. After the use of each instrument, a rinse with NaOCl 2,5% was made. The outcomes evaluated were the presence of apical zip, ledges, perforation, the centering ability and the amount of resin removed.
Results: The photographic analysis of the resin blocks showed a prevalence of apical zips within the undergraduate groups; the expert groups realized a higher number of ledges, while the number of perforations resulted to be higher in the inexpert Stainless-steel control group. The amount of resin removed was significantly higher in the undergraduate WOG group, as well as the centering ability.
Conclusions: The rotary and reciprocating systems provides valid operative standards; by the way, inexpert operators showed major difficulties managing the reciprocating system. More studies are required to assess this parameter.
期刊介绍:
The Giornale Italiano di Endodonzia was founded in 1987 and is the official journal of the Italian Society of Endodontics (SIE). It is a peer-reviewed journal publishing original articles on clinical research and/or clinical methodology, case reports related to Endodontics. The Journal evaluates also contributes in restorative dentistry, dental traumatology, experimental pathophysiology, pharmacology and microbiology dealing with Endodontics.
