Measurement of the mandibular dental arch in Baghdad patients

We measured the dental arch of 220 Baghdad patients (120 females and 100 males) attending the University of Baghdad Dental Clinic. Alginate impressions were taken from which stone casts were made. Specified points were noted on the casts and length and width measurements were taken. We found that the length measurements were smaller than the width measurements indicating an ovoid shape of arch. Also, the size of male arches was greater than those of females.
