Objective: Evaluating the effects of maxillary and mandibular right and left side tooth size discrepancies on achieving dental midline symmetry and favorable orthodontic occlusion. Materials and Method: 90 pretreatment dental casts, selected randomly and in permanent dentition, were grouped according to the Bolton analysis as Average Bolton Group (ABG; n:67) and High Bolton Group (HBG; n:23). To designate the left and right dentition size asymmetries and calculate the mesiodistal width of the mandibular and maxillary teeth, a digital caliper was used on orthodontic casts. The hypothesis was tested using a statistical hypothesis test. To statistically compare ABG and HBG groups, the independent samples “t” test was used. The results were evaluated at a significance level of p<0.05. Results: The difference between the total width of the upper right and left dentition was 0.65±0.55 mm (p<0.05) and the difference between the width of the lower right and left dentition was 0.55±0.49 mm (p<0.05) in the ABG, while in HBG the difference between the sum of the upper right and left dentition was 0.55±0.39 mm (p<0.05) and the difference between the sum of the lower right and left dentition was 0.53±0.43 mm (p<0.05). There were no statistically significant differences between the ABG and HBG (p>0.05) according to the independent samples “t” test. Conclusions: The results indicated that there are minimal but statistically significant differences between the right and left mesiodistal tooth width totals both in ABG and HBG that should be considered to attain favorable orthodontic treatment results and dental midline symmetry.
