When replacing the maxillary central incisor (MCI) or adjusting its dimensions, Syrian dentists may have difficulties in selecting the appropriate size due to the lack of a dental anthropometric database for Syrian society. The purpose of this observational study was to investigate the correlation between MCI dimensions and face length and width in Syrian females and males. The study included 180 Syrian participants (90 females and 90 males) without facial or dental defects and aged between 20 and 25 years. A digital photograph of each individual's face was taken to measure face length and width. Maxillary stone casts were made for each individual to assess the MCI width and height using a digital caliper. The correlation between facial and dental variables was investigated with the Pearson correlation coefficient. Moreover, intersex variations were tested using an independent-sample -test ( < 0.05 considered significant). The mean MCI width was 8.58 mm, the mean MCI cervical width was 7.96 mm, the mean MCI height was 9.69 mm, the average MCI width-to-height ratio was 89%, and the average MCI cervical width-to-height ratio was 82%. The intersex variations in dental values were not statistically significant. None of the studied facial dimensions showed any significant correlation with any of the MCI measurements. The faces of Syrian men were larger than those of Syrian women, but their MCIs had similar proportions and sizes. Facial height and width were not the appropriate parameters for determining MCI size for Syrians.
当替换上颌中切牙(MCI)或调整其尺寸时,由于缺乏叙利亚社会的牙颌测量数据库,叙利亚牙医可能难以选择合适的尺寸。本观察性研究的目的是调查叙利亚女性和男性的 MCI 尺寸与面部长度和宽度之间的相关性。该研究纳入了 180 名无面部或牙齿缺陷且年龄在 20 至 25 岁之间的叙利亚参与者(90 名女性和 90 名男性)。对每个人的面部拍摄了数码照片,以测量面部长度和宽度。为每个人制作上颌石膏模型,使用数字卡尺评估 MCI 宽度和高度。使用 Pearson 相关系数研究面部和牙齿变量之间的相关性。此外,使用独立样本 t 检验测试两性间差异(<0.05 视为显著)。MCI 的平均宽度为 8.58mm,MCI 颈宽的平均值为 7.96mm,MCI 高度的平均值为 9.69mm,MCI 宽度与高度的平均比值为 89%,MCI 颈宽与高度的平均比值为 82%。牙齿值的两性间差异无统计学意义。研究中的任何面部尺寸均与任何 MCI 测量值均无显著相关性。叙利亚男性的脸比女性的大,但他们的 MCI 具有相似的比例和尺寸。面部高度和宽度不适合用于确定叙利亚人 MCI 尺寸的参数。
