Abstract
The aim of the study was to determine the combined mesiodistal widths of the permanent mandibular incisors and maxillary and mandibular canines and premolars in a group of Egyptian children in Giza governorate. Correlate between the combined mesiodistal widths of the teeth under study. A sample of three hundred patients with an age range from twelve to fifteen years attending the outpatient clinics of Giza hospitals was considered. Upper and lower impressions were taken. Each impression was poured immediately in stone plaster. Mesio-distal widths of mandibular incisors and maxillary and mandibular canines and premolars was measured from the study models using digital caliper. No statistically significant difference in the mean mesiodistal tooth width between right and left sides in all teeth under study. Males showed larger mesiodistal tooth width than females. Positive correlations were found between mesiodistal teeth width of mandibular incisors and maxillary and mandibular canines and premolars. The mesiodistal width of upper and lower canines and premolars can be predicted by measuring the mesiodistal width of lower incisors due to the positive correlation found between them
