“…The mean difference between the actual and predicted values of canines and premolars using Moyer's method at 75th percentile and Tanaka-Johnston mixed dentition analysis were clinically and statistically significant. This is in accordance with previous studies [13][14][15][16].…”

Objective: To evaluate the applicability of two different non-radiographic mixed dentition analysis in school going children of Aligarh district, India. Material and Methods: Mesiodistal dimension was measured on the dental casts of 120 school going children with electronic digital vernier caliper. The following inclusion criteria were adopted: presence of all fully erupted permanent teeth; no congenital craniofacial anomalies; no previous history of orthodontic treatment; and presence of intact dentition with no proximal caries, restoration, or age related attrition. Predicted values of canines and premolars were obtained from Moyer's at 75th percentile and Tanaka and Johnston mixed dentition analysis. Descriptive statistics were used to calculate the mean and standard deviation. Paired observations were compared by t-test. The level of significance was at p<0.001. Results: The mean difference between the predicted and the actual value of canines and premolars using Moyer's probability table at 75th percentile and Tanaka and Johnston regression equation were statistically significant. No significant differences were found between Moyer's analysis 75th percentile and Tanaka and Johnston mixed dentition analysis in both arch and sexes. Conclusion: These two non-radiographic mixed dentition analysis overestimated the mesiodistal width of canines and premolars.

“…[2] Camilo et al, method in the present study showed low correlations in the mandible for girls and for boys' highest correlations after the Moyer's method. When this method was used on Indian population by Tikku et al, [9] and Shah et al, [10] significant difference was found, thereby confirming racial variation.…”

“…Other authors (Bachmann, 1986;Gross and Hasund, l989;Tränkmann etal., 1990; [Croatian population] [2] Camilo et al, 2007 [Brazilian population] [8] ) have used regression analysis for predicting the MDD of the unerupted canines and premolars. When Camilo et al, method was used in other studies by Tikku et al, [9] and Shah et al, [10] in Indian population, significant difference was found.…”

Objective: To determine the most reliable mixed dentition analysis method for Nalgonda population. Materials and Methods: This study was conducted on 60 boys and 60 girls of Nalgonda population, in the age group of 13-16 years. The mesiodistal and buccolingual dimensions of the permanent incisors, canines, premolars, and 1 st permanent molars were measured on the study models of all the subjects. Seven different mixed dentition analyses were performed which include Bachmann's, Gross and Hassund's, Trankmann et al., Camilo et al., Legovic et al., Tanaka-Johnston and Moyer's methods and were later compared. The Pearson's Correlation coefficients were calculated between the sums of the mesiodistal diameters (MDDs) of permanent canine, and premolars as measured on the study models and the predicted MDDs of the same using each of these seven methods. Results: The correlation coefficient r was highest for Moyer's mixed dentition analysis with a value of 0.957 and 0.979 in the mandibular and maxillary arch respectively for boys and 0.935 and 0.946 in the mandibular and maxillary arch respectively for girls. Conclusion: Moyer's mixed dentition analysis was found to be the most reliable method for both boys and girls of Nalgonda population of all the 7 methods compared.

“…Based on this studied population, the Moyers Tables may be considered reliable for predicting the mesiodistal diameters of the unerupted canines and premolars, providing a fast diagnosis with respect to the lack or excess of spaces, allowing orthodontic treatment to be performed as early as possible (URZAL et al, 2013;SHAH et al, 2013).…”

ABSTRACT:This study aimed to evaluate the applicability and reliability of Moyers' probability tables in a sample population of youngsters in the Northeast of Brazil. A total of 200 plaster casts of the mandibular arch were evaluated, whom 99 were men and 101 females, aged 15-19 years. For this purpose a digital pachymeter was used to measure the mesiodistal widths of the tooth crowns. The values of the mesiodistal diameters obtained were submitted to statistical analysis by simple linear regression. Only the canine/premolar segment presented significant difference (p<.001) between the mesiodistal diameters of the individuals of the male and female genders, and the male gender presented broader teeth. The regression equations for the mandibular arch for men, Y= 13.42 + 0.37(X) and women, Y= 8.79 + 0.55(X), demonstrated that Moyers' tables with 75 percentage levels, tended to underestimate the real sum of the mandibular permanent canine and premolar of individuals of the male and female gender, however, without statistical difference (p>.05). It could be concluded that there was sexual dimorphism in the size of the teeth for the canine/premolar segment, with men presenting broader teeth. Moyers' probability tables were shown to be reliable for application in white individuals in the Northeast of Brazil.

Applicability of regression equation using widths of mandibular permanent first molars and incisors as a predictor of widths of mandibular canines and premolars in contemporary Indian population

Abstract: From this study, it can be evaluated that Melgaço's method gives better prediction and a simplified equation Y = 0.925X can be suggested for the present population.
