“…The period of late primary or early mixed dentition is a critical period for prevention or interception of any developing malocclusion 1) . Moreover, treatment of malocclusion in the period of active growth is advantageous, because of the opportunities of occlusal guidance, interception of malocclusion or removal of etiological factors 8,13) .…”

This study was done to examine the applicability of the Tanaka and Johnston and Moyers' methods of prediction in Egyptian population and to develop a new prediction method for this specific population if necessary. A total of 325 Egyptian students 145 female, 180 male, mean age 14.4 years, SD±1.1 years were randomly selected from 10 preparatory and secondary schools in Mansoura city, Dakahlia governorate, Egypt during the academic year 2008-2009. The mesiodistal crown diameters of the permanent teeth were measured and compared with the predicted values derived from the Tanaka and Johnston's equations and from Moyers' probability tables at 35%, 50% and 75%. Significant sexual dimorphism was found in tooth sizes. There were significant differences between the actual measurements and that derived from the Tanaka and Johnston's equation and Moyers' tables. New linear regression equations were derived for both genders to allow accurate tooth size prediction in Egyptians. The correlation coefficients between the total mesiodistal width of the mandibular permanent incisors and that of the maxillary and mandibular canines and premolars were found to be 0.78 and 0.89 in male and 0.63 and 0.87 in female, respectively. It can be concluded that there is a limitation in the application of the Tanaka and Johnston's and Moyers' prediction methods to Egyptian population. The developed prediction equation is more accurate for predicting the mesiodistal widths of unerupted canine and premolars of Egyptian population. mixed dentition space analysis results could lead to extraction decisions that negatively alter a patient's soft-tissue facial profile 7). Moyers' probability tables and Tanaka and Johnston's equations are commonly used 8,9) as no radiographs are required, tables can be used for both the maxillary and mandibular arch estimations, and there is a fairly good accuracy despite a tendency to overestimate the size of unerupted teeth 10). The development of these two methods, however, was based on data derived from a population of Northern European descent. Therefore, the accuracy of these prediction methods may be in question when applied to a population of different ethnic origin 11) , as significant differences in tooth sizes exist among different ethnic populations 8,10,12,13). On the other hand, there are only a few published data on mixed dentition analysis for Arabic populations 5,11,14). Therefore, this study was carried out for the

“…Most malocclusions are apparent during the mixed dentition stage and at this time during occlusal development, there are the potential advantages of favourable growth modification, space management and guidance of eruption. An appropriate mixed dentition space analysis (MDS) helps to reduce the severity of a developing malocclusion or even eliminate it, if timely interceptive treatment is initiated (Moyers, 1988;Kuswandari et al, 2006). An accurate forecast of the size of unerupted teeth versus the available space helps orthodontists to make correct decisions regarding treatment options for the patient, whether to involve serial extraction, eruption guidance, space management, space regaining or just periodic observation of the patient (Hukaba, 1964;Smith et al, 1979;Bishara and Jakobsen, 1998;Lee-Chan et al, 1998;Luu et al, 2011).…”

“…Simple linear regression equation was formulated for mixed dentition space analysis for many population around the world. [ 11 12 13 14 15 16 ] A review of the literature revealed that Moyer's prediction tables of mixed dentition analysis were not an accurate method to estimate the tooth dimension in Senegal;[ 17 ] Indonesian Javanese;[ 18 ] Belgaum[ 19 ] and in other Arab population.

Objective:The aim was to formulate a prediction regression equation for Yemeni and to compare it with Moyer's method for the prediction of the size of the un-erupted permanent canines and premolars.Subjects and Methods:Measurements of mesio-distal width of four permanent mandibular incisors, as well as canines and premolars in both arches were obtained from a sample of 400 school children aged 12-14 years old (13.80 ± 0.42 standard deviation) using electronic digital calliper. The data were subjected to statistical and linear regression analysis and then compared with Moyer's prediction tables.Results:The result showed that the mean mesio-distal tooth widths of the canines and premolars in the maxillary arch were significantly larger in boys than girls (P < 0.001), while, in the mandibular arch, only lateral incisors and canines were also significantly larger in boys than in girls (P < 0.001). Regression equations for the maxillary arch (boys, Y = 13.55 + 0.29X; girls, Y = 14.04 + 0.25X) and the mandibular arch (boys, Y = 9.97 + 0.40X; girls, Y = 9.56 + 0.41X) were formulated and used to develop new probability tables following the Moyer's method. Significant differences (P < 0.05) were found between the present study predicted widths and the Moyer's tables in almost all percentile levels, including the recommended 50% and 75% levels.Conclusions:The Moyer's probability tables significantly overestimate the mesio-distal widths of the un-erupted permanent canine and premolars of Yemeni in almost all percentile levels, including the commonly used 50% and 75% levels. Therefore, it was suggested with caution that the proposed prediction regression equations and tables developed in the present study could be considered as an alternative and more precise method for mixed dentition space analysis in Yemeni.
