20 - Correlation coefficients between measured and predicted according to Pont dental arch widths were low. Disapproved (underestimation)
Gupta et al. [4] 100 North
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
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
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
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)
