Disharmony between tooth size and dental arch size induces orthodontic problems. So, dental indices were identified by various authors. One of these is Pont who determined a method of prediction of the ideal dental arch width which has become known as Pont's Index. The purpose of this study was to assess the applicability of Pont's Index to a Turkish population and to compare the results with those obtained from studies of different ethnic subjects. The sample comprised 64 male subjects and 78 female subjects with age range from 14 to 15 years. Measurements were obtained directly from plaster casts; they included mesiodistal crown diameters of the four maxillary incisors, as well as interpremolar and intermolar maxillary arch widths as specified by Pont. Correlation coefficients determined between the measured arch width values and those calculated according to Pont's Index were low in all cases, with r values ranging from 0.02 to 0.36. It was concluded that Pont's Index should not be used to predetermine ideal arch width values in Turkish individuals.
牙齿大小与牙弓大小之间的不协调会引发正畸问题。因此,不同的作者确定了各种牙齿指数。其中之一是庞特,他确定了一种预测理想牙弓宽度的方法,即庞特指数。本研究的目的是评估庞特指数在土耳其人群中的适用性,并将结果与不同种族受试者的研究结果进行比较。样本包括64名男性受试者和78名女性受试者,年龄在14至15岁之间。测量直接从石膏模型上获取;测量内容包括四颗上颌切牙的近远中牙冠直径,以及庞特所规定的上颌磨牙间和前磨牙间牙弓宽度。在所有情况下,测量的牙弓宽度值与根据庞特指数计算的值之间的相关系数都很低,r值范围为0.02至0.36。得出的结论是,庞特指数不应被用于预先确定土耳其个体的理想牙弓宽度值。
