Abstract
Purpose: This clinical study aimed to evaluate the color measurement ability of intraoral scanners (Trios 3, (3Shape, Copenhagen, Denmark) and Cerec Omnicam, (Dentsply Sirona, Charlotte, NC, USA) in comparison to VITA Classical and VITA 3D-Master shades obtained by a spectrophotometer (Easyshade V, VITA, Zahnfabrik, Bad Säckingen, Germany).
Methods: Four hundred eighty teeth from thirty patients were included in the study. Fifteen patients had never undergone bleaching, and the other fifteen had undergone professional bleaching within the last 6 months. VITA Classical and VITA 3D Master shades were determined using Trios 3 (T3), Cerec Omnicam (CO), and EasyShade V from cervical, middle, and incisal/occlusal areas of maxillary and mandibular central and lateral incisors, canines, and first premolars. Color accuracy rates (cAR) were assessed by categorizing the color data according to the Munsell color system for bleached and unbleached teeth, maxillary and mandibular, and teeth arranged from anterior to posterior in each quadrant. McNemar, Mann-Whitney U, and Wilcoxon tests and Point Biserial Correlation Analysis were used for statistical analysis (significance level α=0.050).
Results: The bleached teeth had a significantly higher cAR for T3 in VITA 3D Master and VITA Classical guides (p<0.05). The cAR of the incisal area in VITA 3D Master was significantly lower in both scanners (p<0.05) except for the lightness/hue/chroma of bleached teeth. T3 cAR increased statistically significantly from anterior to posterior (p<0.001); however, no significant difference was found for CO (p=0.482).
Conclusion: The color accuracy rates of both scanners for shade guides that included all color components in this study were below 30%, which was not clinically satisfactory for color measurement. Confirming the measurements with a spectrophotometer is recommended.
目的：本临床研究旨在评估口内扫描仪（丹麦哥本哈根 3Shape 公司的 Trios 3 扫描仪和美国北卡罗来纳州夏洛特 Dentsply Sirona 公司的 Cerec Omnicam 扫描仪）与分光光度计（德国 Bad Säckingen 的 VITA Zahnfabrik 公司的 Easyshade V 分光光度计）所获得的 VITA Classical 和 VITA 3D-Master 色调的颜色测量能力：研究对象包括三十名患者的四百八十颗牙齿。其中 15 名患者从未进行过漂白，另外 15 名患者在过去 6 个月内进行过专业漂白。使用 Trios 3 (T3)、Cerec Omnicam (CO) 和 EasyShade V 对上颌和下颌中切牙、侧切牙、犬齿和第一前臼齿的颈部、中部和切缘/咬合区进行了 VITA Classical 和 VITA 3D Master 色度测定。根据 Munsell 颜色系统对漂白和未漂白牙齿、上颌和下颌以及每个象限从前向后排列的牙齿的颜色数据进行分类，从而评估颜色准确率（cAR）。统计分析采用 McNemar、Mann-Whitney U、Wilcoxon 检验和点比色相关分析（显著性水平 α=0.050）：结果：在 VITA 3D Master 和 VITA Classical 导板中，漂白牙齿的 T3 cAR 明显更高（p 结论：两台扫描仪的颜色准确率都很高：在本研究中，两台扫描仪对包含所有颜色成分的牙色指南的颜色准确率均低于 30%，这在临床上并不能满足颜色测量的要求。建议使用分光光度计确认测量结果。
期刊介绍：
Operative Dentistry is a refereed, international journal published bi-monthly and distributed to subscribers in over 50 countries. In 2012, we printed 84 articles (672 pages). Papers were submitted by authors from 45 countries, in the categories of Clinical Research, Laboratory Research, Clinical Techniques/Case Presentations and Invited Papers, as well as Editorials and Abstracts.
One of the strong points of our journal is that our current publication time for accepted manuscripts is 4 to 6 months from the date of submission. Clinical Techniques/Case Presentations have a very quick turnaround time, which allows for very rapid publication of clinical based concepts. We also provide color for those papers that would benefit from its use.
The journal does not accept any advertising but you will find postings for faculty positions. Additionally, the journal also does not rent, sell or otherwise allow its subscriber list to be used by any other entity
