“…It was also interesting to note that mandibular incisor showed the smallest differences between sexes. This was consistent with the results reported by Al-Bitar,[21] Jensen,[17] Bishara et al .,[20] Hattab et al .,[22] and Yeun et al . [23] Thus, this necessitates the need for separate prediction formula and probability tables for males and females.…”

Aim:To evaluate the applicability of the Tanaka and Johnston (1974) and Moyers (1988) methods in predicting the size of permanent canines and premolars in Chennai school children.Materials and Methods:470 sets (127 female and 343 male) of cast models were included in the sample. Mesio-distal (m-d) widths of all teeth from left to right first molars were measured and compared with the predicted values derived from Tanaka and Johnston and Moyers methods.Results:There was significant bilateral symmetry and sexual dimorphism in teeth sizes seen in both the sexes. Sum of the m-d diameter of permanent mandibular incisors can be used reliably to predict the sum of m-d diameters of unerupted canines and premolars.Conclusions:Tanaka and Johnston's method cannot accurately predict the m-d widths. Moyers’ prediction tables can be used to estimate the m-d widths of unerupted canines and premolars closer to 50% probability level.

“…Numerous methods [1][2][3][4][5][6][7][8][9][10][11][12] for anticipating the space that will be required to accommodate the unerupted permanent canines and premolars into the line of occlusion, with a premise of possible differences between the sexes, have been reported.…”

Objectives: (1) To identify any differences in the accuracy of the prediction of the summed widths of unerupted permanent canines and premolars for males vs females and, if differences are identified, (2) to examine the sex differences in the best combination of independent variables and (3) to evaluate the practical accuracy using our models for both sexes, respectively. Materials and Methods: Records for 200 orthodontic patients (100 males and 100 females) with discernible tooth crowding in the permanent dentition were selected. Mesiodistal tooth crown widths, dental arch widths, and basal arch lengths were measured. Predicted sum widths of permanent canines and premolars in both dental arches were calculated using stepwise regression analysis. Results: Among male subjects, the best combinations of independent variables were the widths of the upper central and lateral incisors (U1, U2) and the first molar (U6) for the maxilla (R 2 5 0.615) and the mandible, lower central and lateral incisors (L1, L2), and the first molar (L6) (R 2 5 0.685), whereas in females, the best combinations for prediction were found to be U1, U2, U6, and the maxillary arch width for the maxilla (R 2 5 0.429) and L1, L2, L6, and the basal arch length for the mandible (R 2 5 0.426). Correlation coefficients between each independent and dependent variable in the female subject group were found to be weaker than those for the male subject group. Conclusions: We found the sex differences in the accuracy of prediction and the best combination of independent variables for predicting the summed widths of unerupted canines and premolars. These new models should be clinically useful, providing highly accurate prediction. (Angle Orthod. 2011;81:938-944.)

“…Mixed dentition analysis is an essential part of early orthodontic diagnostic procedures required to determine the amount of mesiodistal space available for the alignment of unerupted permanent canines and premolars in a dental arches [15,16]. Most of the cases of malocclusion start during the mixed dentition period.…”

Objective: To assess the accuracy and applicability of three regression equations based mixed dentition analysis in children of Moradabad city, India. Material and Methods: Actual mesiodistal width of maxillary and madibular incisors, canines and premolars of 100 children (50 male and 50 female) aged 11-14 years were measured on dental cast with electronic digital vernier caliper. The analysis of Tanaka-Johnston, Ling-Wong and Jaroontham-Godfrey regression equations were tested on the dental casts. All analyses were performed on SPSS software. Data were summarized as Mean ± standard deviation (SD) paired observations were compared by paired t-test (two-tailed test) while independent groups were compared by independent Student's t-test. The level of significance was at P < 0.001. Results: The analysis of Tanaka-Johnston, Ling-Wong, Jaroontham-Godfrey regression equations tended to overestimate the mesiodistal width of the canines and premolars with the actual measured values. Conclusion: All the three regression equations based mixed dentition overestimated the mesiodistal width of canines and premolars in Moradabad population.

Mixed Dentition Analysis in a Jordanian Population

Abstract: There is a limitation in the application of the Tanaka and Johnston's prediction method to a Jordanian population. It is important to use separate equations for male and female patients.
