In achieving pleasing dental aesthetics, the maxillary anterior teeth are essential. Numerous methods are used to measure their dimensions, including the golden proportion between their perceived widths and the width-to-height ratios, referred to as the golden proportion and is considered as a gold standard for esthetic evaluation.The objective of this study was to evaluate the existence of the golden proportion between the width of the maxillary anterior teeth of Saudi males and females.
This clinical observational study included a total of 61 participants that met the inclusion criteria having 36 females and 25 males, all Saudi nationals, presented to Princess Nourah bint Abdulrahman University (PNU), College of dentistry, clinics. Dental casts of the maxillary arches for each participant were made after taking digital impressions in addition to taking photographs. The dimensions and the perceived width of the anterior teeth viewed from the front were measured using a digital caliper. SPSS was used to analyze the data.
There were significant differences between the subject's width-to-height ratios and the golden proportion of 0.80 where (p-value < 0.05). Thus, indicating that no golden ratio was observed except in case of tooth number 12 in male subjects where mean value was (0.83) with a standard deviation of (0.09) and the p-value of (p = 0.144) > 0.05.
From the perceived widths of maxillary anterior teeth, the golden proportion was not found to exist. No gold standard was detected for the width-to-height proportions of maxillary incisors. Therefore, in addition to anterior teeth measurements, specific population characteristics and perception of an agreeable smile should be considered for evaluating esthetics.
在实现令人满意的牙齿美学效果方面,上颌前牙至关重要。有多种方法用于测量其尺寸,包括其感知宽度与宽高比之间的黄金比例,该比例被称为黄金比例,被视为美学评估的黄金标准。本研究的目的是评估沙特男性和女性上颌前牙宽度之间黄金比例的存在情况。
这项临床观察性研究共纳入了61名符合纳入标准的参与者,其中36名女性和25名男性,均为沙特国民,他们前往努拉·本·阿卜杜勒拉赫曼公主大学牙科学院诊所就诊。在进行数字印模并拍照后,为每位参与者制作了上颌牙弓的石膏模型。使用数字卡尺测量从正面观察到的前牙尺寸和感知宽度。使用SPSS分析数据。
受试者的宽高比与0.80的黄金比例之间存在显著差异(p值<0.05)。因此,表明除男性受试者的12号牙外未观察到黄金比例,12号牙的平均值为(0.83),标准差为(0.09),p值为(p = 0.144)>0.05。
从上颌前牙的感知宽度来看,未发现黄金比例的存在。未检测到上颌切牙宽高比例的黄金标准。因此,在评估美学时,除了前牙测量外,还应考虑特定人群特征和对宜人微笑的感知。
