This study aimed to evaluate dentist perceptions of attractive smiles in the Pakistani population, considering different dental proportions.
Maxillary casts and digital images were used to create symmetrical representations of anterior teeth. dentists' preferences for good and bad teeth proportions, width/height ratios, and various dental proportions (golden, recurring esthetic dental (RED), golden percentage, Preston, and local/observed) were assessed using one sample and paired t-test. The Chi-square test was used to determine the gender disparities and factors affecting smile attractiveness. A p-value of ≤ 0.05 was taken as significant.
The RED proportion emerged as the preferred choice for normal-sized teeth, with specialists and general dentists favoring it over the golden proportion. For tall teeth, the golden proportion was predominantly preferred. The golden percentage received limited preference for aesthetic smile construction.
The smiles created using the principles of RED proportion were opted as the most attractive by local dentists. Factors such as tooth arrangement, color, and midline were highlighted as essential considerations in aesthetic smile construction.
本研究旨在评估巴基斯坦人群中牙医对有吸引力的笑容的看法，同时考虑不同的牙齿比例。
使用上颌模型和数字图像创建前牙对称的表示。使用单样本和配对 t 检验评估牙医对好牙和坏牙比例、宽度/高度比以及各种牙齿比例（黄金比例、重现美学牙科（RED）比例、黄金百分比、普雷斯顿比例和本地/观察）的偏好。卡方检验用于确定性别差异和影响微笑吸引力的因素。p 值≤0.05 被视为具有统计学意义。
在正常大小的牙齿中，RED 比例是首选，专家和普通牙医更喜欢 RED 比例而不是黄金比例。对于高牙齿，黄金比例更受欢迎。黄金百分比在美学微笑构建中受到的偏好有限。
当地牙医选择使用 RED 比例原则创建的笑容为最吸引人的笑容。牙齿排列、颜色和中线等因素被强调为美学微笑构建中的重要考虑因素。
