摘要
背景:在插入牙科修复体之前,需要对椅旁调整套件进行热消毒,以便定位和抛光牙科修复体。本研究旨在评估两个蒸汽消毒周期对抛光高透光性整体氧化锆(HTMLZ)牙科修复材料效果的影响。材料和方法 使用 EVE Diacera 套件对 100 个 HTMLZ 盘形试样进行调整(研磨、精加工、抛光)。根据灭菌周期[周期 1(对照组)、周期 5、10、15 和 20(实验组)]的次数,对 CAK 的两种蒸汽灭菌技术[标准(Gp S)、即时/闪光(Gp (F))]进一步分组(各 10 个)。每个分组相应地使用轮廓仪评估平均表面粗糙度(Ra)和均方根粗糙度(Rq)。采用单因素方差分析/事后 Tukey 检验对 5 个亚组的平均值和标准偏差进行统计分析。扫描电子显微镜对 Ra、Rq 的测量进行了补充。统计学差异 P≤0.05 为显著。结果 两组的 HTMLZ 标本在使用 EVE Diacera 套件反复消毒后,Ra/Rq 值均有所增加,Gp F 的增加幅度小于 Gp S(20 个周期)。10 个周期的 Gp F 和 15 个周期的 Gp S 显示出临床上无法接受的粗糙度阈值(0.25 μm)。亚组间的 Ra 值和 Rq 值差异显著(P≤0.05),而在早期循环中观察到的组内差异较小(1,10)。结果验证了制造商关于 EVE Diacera 套件使用闪蒸灭菌/10 个周期的建议。结论 反复消毒会降低椅旁调整套件在 HTMLZ 上制作光滑表面的功效。本研究建议闪光消毒最多 10 次,以获得临床可接受的 Ra 和 Rq 值。
The Impact of Repeated Steam Sterilization Cycles on the Efficacy of Chairside Adjustment Kits for Polishing Monolithic Multi-Layered Zirconia Dental Restoration Material.
BACKGROUND Before insertion, chairside adjustment kits are heat sterilized for positioning and polishing dental restorations. This study aimed to evaluate the effects of 2 steam sterilization cycles on the efficacy of polishing highly translucent monolithic zirconia (HTMLZ) dental restoration material. MATERIAL AND METHODS 100 HTMLZ disc-shaped specimens were adjusted (grinding, finishing, polishing) with EVE Diacera kit. Two steam sterilization techniques [standard (Gp S), immediate/flash (Gp (F)] of CAK were further subgrouped based on number of sterilization cycles [cycle 1 (control), cycle 5, 10, 15, and 20 (experimental)] (n=10 each). Each subgroup accordingly was evaluated for average surface roughness (Ra) and root mean square roughness (Rq) using a profilometer. Mean and standard deviation of 5 subgroups were statistically analyzed using one-way ANOVA/post hoc Tukey's test. Scanning electron microscopy complemented Ra, Rq measurements. Statistical differences of P≤0.05 were considered significant. RESULTS HTMLZ specimens in both groups showed increased (Ra/Rq) values after repeated sterilization of EVE Diacera kit, with Gp F showing lesser increase than Gp S (20 cycles). Gp F at 10 cycles and Gp S at 15 cycles showed clinically unacceptable roughness threshold (0.25 μm). Differences between subgroups for Ra and Rq values were significant (P≤0.05) with less differences within groups observed in early cycles (1, 10). Results validate the manufacturer's recommendations of using flash sterilization/10 cycles for EVE Diacera kit. CONCLUSIONS Repeated sterilization reduces efficacy of chairside adjustment kit to produce smooth surfaces on HTMLZ. This study recommends flash sterilization to a maximum of 10 times to get the clinically acceptable results of Ra and Rq.
期刊介绍:
Medical Science Monitor (MSM) established in 1995 is an international, peer-reviewed scientific journal which publishes original articles in Clinical Medicine and related disciplines such as Epidemiology and Population Studies, Product Investigations, Development of Laboratory Techniques :: Diagnostics and Medical Technology which enable presentation of research or review works in overlapping areas of medicine and technology such us (but not limited to): medical diagnostics, medical imaging systems, computer simulation of health and disease processes, new medical devices, etc. Reviews and Special Reports - papers may be accepted on the basis that they provide a systematic, critical and up-to-date overview of literature pertaining to research or clinical topics. Meta-analyses are considered as reviews. A special attention will be paid to a teaching value of a review paper.
Medical Science Monitor is internationally indexed in Thomson-Reuters Web of Science, Journals Citation Report (JCR), Science Citation Index Expanded (SCI), Index Medicus MEDLINE, PubMed, PMC, EMBASE/Excerpta Medica, Chemical Abstracts CAS and Index Copernicus.
