The authors conducted a study to evaluate the influence of dentists' and nondentists' experience, age, sex, eye color and use of eyeglasses or contact lenses on tooth shade-matching ability.
The authors included 120 participants in this study conducted in Istanbul (periodontists, oral and maxillofacial surgeons, orthodontists, endodontists, pediatric dentists, prosthodontists, restorative dentists, general dentists in private practice, dental technicians, dental assistants, dental assistant students and laypeople). The authors assigned participants to one of three groups: group 1 was composed of prosthodontists, restorative dentists and dental technicians; group 2 consisted of other dental specialists and general dentists; and group 3 included dental assistants, dental assistant students and laypeople. The authors asked participants to match the shades of three artificial maxillary right central incisors (Vitapan acrylic teeth [shades 2L1.5, 1M2, 2R1.5], Vita Zahnfabrik, Bad Säckingen, Germany) by using a shade guide system (Vita Toothguide 3D-Master, Vita Zahnfabrik). They calculated shade matching for the three color components (value, hue, chroma) and analyzed the results by using a chi(2) test.
The rate of success in matching the shade for IM2 was 53.3 percent for participants in group 1, 30 percent for participants in group 2 and 20 percent for participants in group 3 (P = .017). However, there were no significant differences between the three groups for shades 2L1.5 and 2R1.5. Professional experience (P = .003) and age (P = .027) were associated with shade-matching success for tooth shade 2L1.5 only. The results showed no statistically significant differences with respect to sex, eye color or use of eyeglasses or contact lenses.
Dental care professionals who routinely performed restorative procedures matched the shades better than did participants in other groups. Professional experience was associated positively with the outcome, while sex, eye color and use of eyeglasses or contact lenses did not have any effect on shade-matching results.
To improve shade-matching skills, clinicians should participate in hands-on courses, continuing education classes and other training programs.
作者开展了一项研究,评估牙医和非牙医的经验、年龄、性别、眼睛颜色以及是否戴眼镜或隐形眼镜对牙齿比色能力的影响。
作者在伊斯坦布尔纳入了 120 名参与者(牙周病学家、口腔颌面外科医生、正畸医生、牙髓病学家、儿童牙医、修复医生、牙髓医生、私人执业的全科牙医、牙科技师、牙科助理、牙科助理学生和非专业人士)进行了这项研究。作者将参与者分为三组:第 1 组由修复医生、牙髓医生和牙科技师组成;第 2 组由其他牙科专家和全科牙医组成;第 3 组包括牙科助理、牙科助理学生和非专业人士。作者要求参与者使用比色指南系统(Vita Toothguide 3D-Master,Vita Zahnfabrik)匹配 3 颗人工上颌右侧中切牙(Vitapan 丙烯酸牙[色号 2L1.5、1M2、2R1.5],Vita Zahnfabrik,巴德沙伊德根,德国)的颜色。他们计算了 3 种颜色成分(明度、色调、彩度)的比色匹配值,并使用卡方检验分析结果。
对于参与者来说,在色号 IM2 中,第 1 组的匹配成功率为 53.3%,第 2 组为 30%,第 3 组为 20%(P =.017)。然而,对于色号 2L1.5 和 2R1.5,三组之间没有显著差异。只有专业经验(P =.003)和年龄(P =.027)与色号 2L1.5 的比色匹配成功率相关。结果表明,性别、眼睛颜色或是否戴眼镜或隐形眼镜与比色结果之间无统计学差异。
经常进行修复治疗的牙科保健专业人员比其他组的参与者更好地匹配颜色。专业经验与结果呈正相关,而性别、眼睛颜色和是否戴眼镜或隐形眼镜对比色结果没有影响。
为了提高比色技能,临床医生应参加实践课程、继续教育课程和其他培训计划。
