Each patient may have a different idea of a beautiful smile. Also, during treatment, periodontists, restorative dentists and general dentists should be aware that their personal views on the beauty of a smile and their degree of sensitivity in the perception of beauty changes may differ, and this difference may affect the treatment process.
This research seeks to evaluate how alterations in the shape and position of the gingival margin in maxillary anterior teeth influence the perception of smile aesthetics among different groups including periodontists, restorative dentists, general dentists, and non-professionals.
This cross-sectional study was conducted on 60 raters in four groups (n= 15) of periodontists, restorative dentists, general dentists, and non-professionals. The raters received 10 photographs including one original and 9 altered images, and they were asked to rate them regarding smile aesthetics. Data were analyzed by the Kruskal-Wallis, Fisher's exact, and t-test (alpha=0.05).
All four rater groups gave the highest score to the original image and the lowest score to the asymmetrical changes on shape and position of the gingival zenith; the statistical difference in this regard was significant in the group of periodontists, restorative dentists, and general dentists (< 0.05) but not in non-professionals ( Value> 0.05). Males were more sensitive than females in the detection of changes in shape and position of the gingival margin; however, the statistical difference was only significant for images showing an asymmetrical change on the right or left side (< 0.05).
A significant difference in opinion was seen among periodontists, restorative dentists, and general dentists regarding the effect of the shape and position of the gingival margin of maxillary anterior teeth on the perception of smile aesthetics, highlighting the need to reach an interdisciplinary consensus prior to gingivectomy and aesthetic crown lengthening procedures.
每位患者对于美丽笑容可能都有不同的看法。此外,在治疗过程中,牙周病医生、修复牙医和普通牙医应意识到,他们对笑容美的个人观点以及对美变化的感知敏感度可能存在差异,而这种差异可能会影响治疗过程。
本研究旨在评估上颌前牙牙龈边缘的形状和位置改变如何影响包括牙周病医生、修复牙医、普通牙医和非专业人士在内的不同群体对笑容美学的认知。
本横断面研究对牙周病医生、修复牙医、普通牙医和非专业人士四个组(每组n = 15)的60名评分者进行。评分者收到10张照片,包括1张原始照片和9张修改后的图像,并被要求就笑容美学对其进行评分。数据采用Kruskal-Wallis检验、Fisher精确检验和t检验进行分析(α = 0.05)。
所有四个评分者组对原始图像给出的分数最高,对牙龈顶点形状和位置的不对称变化给出的分数最低;在这方面,牙周病医生、修复牙医和普通牙医组的统计差异具有显著性(< 0.05),而非专业人士组则无显著性差异(P值> 0.05)。男性在检测牙龈边缘形状和位置变化方面比女性更敏感;然而,仅对于显示左右不对称变化的图像,统计差异具有显著性(< 0.05)。
牙周病医生、修复牙医和普通牙医在上颌前牙牙龈边缘的形状和位置对笑容美学认知的影响方面存在显著的意见差异,这凸显了在牙龈切除术和美学牙冠延长手术前达成跨学科共识的必要性。
