The maxillary anterior teeth are important in achieving pleasing dental aesthetics. Various methods are used to measure the size and form of them, including the golden proportion between their perceived widths, and the width-to-height ratio, referred to as the golden standard. The purpose of this study was conducted to evaluate whether consistent relationships exist between tooth width and height of the clinical crown dimensions; and to investigate the occurrence of the golden proportion of the maxillary anterior teeth.
Dental casts of the maxillary arches were made in this cross-sectional study from MAHSA University College students who met the inclusion criteria. The 49 participants represented the Malaysian population main ethnics. The dimensions of the anterior teeth and the perceived width of anterior teeth viewed from front were measured using a digital caliper.
Comparison of the perceived width ratio of lateral to central incisor and canine to lateral incisor with the golden proportion of 0.618 revealed there were a significant statistical difference (p < 0.05). The statistical difference was significant for the width-to-height ratio of central incisors to the golden standard of 80%. There was no significant difference in the comparison among ethnic groups for the golden proportion and the golden standard.
The golden proportion was not found to exist between the perceived widths of maxillary anterior teeth. No golden standard were detected for the width-to-height proportions of maxillary incisors. Specific population characteristics and perception of beauty must be considered. However, ethnicity has no association with the proportions of maxillary anterior teeth.
上颌前牙对于获得令人满意的牙齿美观至关重要。有多种方法可用于测量其大小和形状,包括感知宽度之间的黄金比例,以及被称为黄金标准的宽度与高度比。本研究旨在评估临床牙冠尺寸的牙齿宽度和高度之间是否存在一致的关系;并研究上颌前牙的黄金比例是否存在。
在这项横断面研究中,从符合纳入标准的 MAHSA 大学学院的学生中制作上颌牙弓的牙模。49 名参与者代表马来西亚主要种族的人口。使用数字卡尺测量前牙的尺寸和从前部观察到的前牙感知宽度。
比较侧门齿与中门齿以及犬齿与侧门齿的感知宽度比与黄金比例 0.618 显示出显著的统计学差异(p < 0.05)。中切牙的宽高比与黄金标准 80%的统计学差异显著。在黄金比例和黄金标准方面,不同种族之间的比较没有显著差异。
未发现上颌前牙感知宽度之间存在黄金比例。上颌切牙的宽高比没有检测到黄金标准。必须考虑特定人群的特征和美感认知。然而,种族与上颌前牙的比例无关。
