Joondeph et al. [2] |
20 | - | Correlation coefficients between measured and predicted according to Pont dental arch widths were low. | Disapproved (underestimation) |
Gupta et al. [4] | 100 |
North Indian |
Significant correlations were found to exist between combined maxillary incisor widths and the maxillary interpremolar and intermolar arch widths. Suggested values of Index: 81.66 for premolars and 65.44 for molars. |
Approved (with different values of Index) |
Stifter [5] | 57 |
Navaho Indians |
In the group of subjects with ideal occlusion significant correlation existed between the combined incisor widths and the molar and upper premolar widths. No corresponding correlation could be found in the subjects with normal occlusion. The lower premolar width had no significant correlation to incisor width in both groups. | Approved |
Al-Omari et al. [6] |
144 | Jordanian | Correlation coefficients were low in all cases (with r values ranging from 0.25 to 0.39). | Disapproved (overestimation) |
Hong et al. [10] | 100 | Nepalese | Correlation coefficients were very low in all cases (with r values ranging from 0.07 to 0.29). | Disapproved (overestimation) |
Sridharan [11] | 62 | Tumkur | Correlation coefficients were statistically significant. It was concluded that Pont’s Index can be applied in Tumkur population. | Approved |
Nimkarn et al. [12] |
40 | Caucasians | Interpremolar widths were more strongly correlated than intermolar widths. Pont’s Index overestimated the interpremolar and intermolar arch widths by 4.7 and 2.5 mm respectively. | Disapproved (overestimation) |
Ordoubazary et al. [13] | 80 | Iranian | There was a statistically significant difference between predicted and calculated dental arch widths. | Disapproved (overestimation) |
Thu et al. [14] | 85 | Malay | Predicted dental arch measurements were significantly greater than measured ones. | Disapproved (overestimation) |
