Abstract
Objective: To evaluate the validity of Pont’s index in Nepalese population and establish the regression equation to predictprobable arch width from sum of the maxillary incisors.Materials & Method: The sample comprised of 50 female and 50 male subjects of the age ranging 17-24 years. Sum of themesio-distal widths of the maxillary incisors were measured. Descriptive statistics, Coefficient of regression, and regressionequation were calculated to predict the arch width in premolar and molar regions. Independent t-test was performed to findthe difference between mean values of male and female subjects. Statistical analysis was done using SPSS version 17.0.Result: Mean value of Pont’s index ratio was 0.80 and 0.63 for premolar and molar respectively for Nepalese sample. Statisticalanalysis showed no significant difference between male and female in Pont’s premolar and molar index. The correlation ofcoefficient for Sum of Incisors/Premolar width and Sum of Incisors/Molar width were 0.39 and 0.46 respectively.Conclusion: Pont’s analysis can be applied in Nepalese samples. There is no significant difference in values between male andfemale samples.DOI: http://dx.doi.org/10.3126/ojn.v4i1.11305 Orthodontic Journal of Nepal Vol.4(1) 2014; 12-16
Highlights
Various model analytical indices have been proposed in orthodontics to help in diagnosis and treatment planning
Premolar arch width is termed as measured premolar value (MPV); which was measured from distal pit on occlusal surface of right first premolar to distal pit on occlusal surface of left first premolar
The predicted arch widths of premolar is termed as calculated premolar value (CPV) and in molar as calculated molar value (CMV); which were established using the formula originally proposed by Pont
Summary
Various model analytical indices have been proposed in orthodontics to help in diagnosis and treatment planning. Pont in 1909 proposed a method to predict arch width, which is popularly known as Pont’s index.[4] According to this method, by mere measurement of four maxillary incisors, arch width in premolar and molar region can be estimated. All of these measurements and predictions are related to maxillary arch and do not include mandibular arch.
