“…After computing the predicted widths from the developed regression equations, a paired sample t -test was applied to compare actual and predicted measurements. A nonsignificant difference was shown between the predicted and actual mesiodistal crown dimensions of both the maxillary and mandibular canines and premolars ( Table 4 ); this result agrees with previous studies [ 6 – 9 , 11 – 13 , 17 , 18 ]. The mean differences between the measurements were clinically and statistically insignificant.…”

Objectives. The current study aimed to predict the combined mesiodistal crown widths of maxillary and mandibular canines and premolars from the combined mesiodistal crown widths of maxillary and mandibular incisors and first molars. Materials and Methods. This retrospective study utilized 120 dental models from Iraqi Arab young adult subjects with normal dental relationships. The mesiodistal crown widths of all teeth (except the second molars) were measured at the level of contact points using digital electronic calipers. The relation between the sum mesiodistal crown widths of the maxillary and mandibular incisors and first molars and the combined mesiodistal crown widths of the maxillary and mandibular canines and premolars was assessed using Pearson’s correlation coefficient test. Based on this relation, regression equations were developed to predict the sum widths of maxillary and mandibular canines and premolars; then, the predicted mesiodistal crown sum widths were compared with the actual one using a paired sample t-test. Results. Statistically, the predicted mesiodistal crown sum widths were nonsignificantly different from the actual ones. Conclusions. The combined mesiodistal widths of maxillary and mandibular canines and premolars can be predicted successfully from the combined mesiodistal widths of the maxillary and mandibular incisors and first molars with a high degree of accuracy reaching to more than 86%.

“…After computing the predicted widths, paired sample t-test was applied to compare the actual and predicted measurements. Non-significant difference was shown between the predicted and actual mesio-distal crowns dimensions of both maxillary and mandibular canines and premolars (Table 3), this comes in agreement with previous studies (11)(12)(13)(14)17,18,20,29) . The mean differences between the measurements were clinically negligible.…”

“…These methods may not be applicable for all racial groups as they may give an over-estimated result. Many other methods (4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) utilized the regression analysis test using the widths of the maxillary or mandibular anterior teeth and 1 st molars had reached to acceptable results in different racial groups. In Iraq, many researches have been performed to predict the canines and premolars widths using different methods (21)(22)(23)(24)(25)(26)(27)(28)(29) and this is a new study utilized the combined mesio-distal crowns widths of maxillary…”

Pearson's correlation coefficient test was used to determine the relation between the combined mesio-distal crowns widths of maxillary and mandibular central incisors and first molars and the combined mesio-distal crowns widths of maxillary and mandibular canines and premolars. The equations that predict the widths of maxillary and mandibular canines and premolars were obtained using simple regression analysis test. Paired sample t-test was used to compare between the actual and predicted mesio-distal crown widths.Results: Non-significant differences between the predicted and actual mesio-distal crown widths were shown in this study. Conclusions:The combined mesio-distal widths of maxillary and mandibular central incisors and first molars can be used to predict the combined mesio-distal crown widths of maxillary and mandibular canines and premolars with a high percentage of accuracy reaching to more than 80%.

“…Various published articles attempted to predict the width of premolars and canines using a prediction approach based on the first permanent incisors and molars, which erupted early in life [ 9 – 25 ]. Caries can often impair the first molars, resulting in an eventual loss in children at nine to ten years old.…”

Background. The purpose of the present study was to use the combined mesiodistal crown widths of the mandibular and maxillary incisors as predictors for the combined mesiodistal crown widths of mandibular and maxillary canines and premolars. Materials and Methods. One hundred and twenty pairs of study models belong to 120 Iraqi adult subjects with normal dental and skeletal relations were included in the study. The crown widths of the mandibular and maxillary incisors, canines, and premolars were assessed at the maximum mesiodistal dimension on the dental casts using a digital electronic caliper with 0.01 mm sensitivity. The correlation between combined mesiodistal crown widths of the mandibular and the maxillary incisors and combined mesiodistal crown widths of mandibular and maxillary premolars and canines has been determined using Pearson’s coefficient correlation test for each arch and gender. Using simple regression analysis, the equations predicting the widths of the mandibular and maxillary premolars and canines were established. The predicted and the actual mesiodistal crown width values have been compared with the use of a paired sample t-test. Results. According to the findings of the present study, males had significantly wider teeth compared to females. Correlations between the measured parameters ranged from moderate to strong. A nonsignificant difference between actual and predicted mesiodistal crown widths was discovered. Conclusions. With a high degree of accuracy, the combined mesiodistal widths of the maxillary and the mandibular incisors could be utilized for predicting the combined mesiodistal crown widths of the mandibular and maxillary canines and premolars.

Predicting the mesiodistal width of unerupted canine and premolars by using width of the permanent mandibular incisors and first molar in the Himachal population

Abstract: From this study, it can be evaluated that Melgaco's method gives better prediction of unerupted permanent canines and premolars, and the equation Y = 13.48 + 0.614X can be suggested for the present population.
