This cross-sectional study verified the self perception of different observers on gingival recession.
Areas of gingival recession were digitally modified using software simulating different clinical conditions in the esthetic area. A total of 180 individuals (60 dentists, 60 patients, and 60 dental students) participated in this study. From an original photograph of the smile of a volunteer, five cases of gingival recession (GR), including unilateral recession (lateral incisor and canine), bilateral recession (lateral incisor and canine), and generalized recession in upper anterior teeth, were intentionally created with Adobe Photoshop 2015™ image-editing software. The participants analyzed the photographs with scores of 1 (very pleasant), 2 (pleasant), and 3 (unpleasant). The data were evaluated using Student's t-test and ANOVA with Tukey's post hoc test at p less than 0.05.
Unilateral recession was considered more esthetically pleasing when compared to bilateral recession, showing a signifi cant difference for all groups (p less than 0.05). Patients considered generalized recession and bilateral recession of upper canines less esthetic (p less than 0.05).
Within the limits of this study, it could be concluded that dentists have better visual perception when compared to dental students, who in turn were more perceptive than patients.
本横断面研究验证了不同观察者对牙龈退缩的自我认知。
使用软件对美学区域的牙龈退缩区域进行数字修改,模拟不同临床情况。共有180人(60名牙医、60名患者和60名牙科学生)参与了本研究。利用Adobe Photoshop 2015™图像编辑软件,从一名志愿者的原始微笑照片中,故意制造出5例牙龈退缩(GR)情况,包括单侧退缩(侧切牙和尖牙)、双侧退缩(侧切牙和尖牙)以及上前牙广泛性退缩。参与者对照片进行评分,1分表示“非常愉悦”,2分表示“愉悦”,3分表示“不愉悦”。使用学生t检验和方差分析,并采用Tukey事后检验对数据进行评估,p值小于0.05。
与双侧退缩相比,单侧退缩被认为在美学上更令人愉悦,所有组均显示出显著差异(p值小于0.05)。患者认为上前牙广泛性退缩和双侧尖牙退缩的美观度较低(p值小于0.05)。
在本研究的范围内,可以得出结论,与牙科学生相比,牙医具有更好的视觉感知能力,而牙科学生又比患者更具感知力。
