In this study, the reproducibility of a newly developed pink esthetic score (PES) for evaluating soft tissue around single-tooth implant crowns was assessed. The effect of observer specialization was another point of interest.
Twenty observers (five prosthodontists, five oral surgeons, five orthodontists and five dental students) were given photographs of 30 single-tooth implant crowns. Seven variables were evaluated vs. a natural reference tooth: mesial papilla, distal papilla, soft-tissue level, soft-tissue contour, alveolar process deficiency, soft-tissue color and texture. Using a 0-1-2 scoring system, 0 being the lowest, 2 being the highest value, the maximum achievable PES was 14. Each observer was requested to make two assessments at an interval of 4 weeks. At the second assessment, the photographs were scored in the reverse order.
The mean PES of evaluations at the first assessment (n=600) was 9.46 (+/-3.81 SD), and 9.24 (+/-3.8 SD) at the second one. The difference between these two means was not significant statistically (P=0.6379). Implant-related mean PES for single-tooth implants varied from 2.28 to 13.8, with standard deviations between 0.46 and 3.51. Very poor and very esthetic restorations showed the smallest standard deviations. The mean total PES was 10.6 for the prosthodontists, 9.2 for the oral surgeons, 9.9 for the dental students and 7.6 for the orthodontists.
The PES reproducibly evaluates peri-implant soft tissue around single-tooth implants. Thus, an objective outcome of different surgical or prosthodontic protocols can be assessed. Orthodontists were clearly more critical than the other observers.
在本研究中，评估一种新开发的用于评估单颗牙种植体牙冠周围软组织的粉色美学评分（PES）的可重复性。观察者专业化的影响是另一个关注点。
向20名观察者（5名口腔修复科医生、5名口腔外科医生、5名正畸医生和5名牙科学生）提供30颗单颗牙种植体牙冠的照片。对照天然参照牙评估7个变量：近中乳头、远中乳头、软组织水平、软组织轮廓、牙槽突缺损、软组织颜色和质地。采用0 - 1 - 2评分系统，0为最低值，2为最高值，最高可达到的PES为14分。要求每位观察者间隔4周进行两次评估。在第二次评估时，照片按相反顺序评分。
第一次评估（n = 600）时的平均PES为9.46（±3.81标准差），第二次评估时为9.24（±3.8标准差）。这两个平均值之间的差异无统计学意义（P = 0.6379）。单颗牙种植体与种植体相关的平均PES在2.28至13.8之间，标准差在0.46至3.51之间。非常差和非常美观的修复体标准差最小。口腔修复科医生的平均总PES为10.6，口腔外科医生为9.2，牙科学生为9.9，正畸医生为7.6。
PES可重复评估单颗牙种植体周围的种植体周围软组织。因此，可以评估不同手术或修复方案的客观结果。正畸医生明显比其他观察者更严格。
