Aim: The current study was conducted for assessment of arch dimensions among children with surgically repaired unilateral cleft lip and palate.Methodology: This Observational (cross-sectional) study was conducted on 233 unilateral cleft lip and palate patients aged from 8-10 years and had been operated with lip and palate closure. They were selected from Orthodontics Department at Faculty of Dentistry, Cairo University, and from Pediatric Dentistry Department at Faculty of Dentistry, Cairo University, and from Pediatric Surgery Clinic for Orofacial Clefts, Abu El Reesh Children{u2019}s Hospital, Cairo University. After an informed consent was taken by their parents, Extra and intra-oral examination was done by the main investigator then impressions of the upper and lower arches of all participating children were performed.The impressions were poured immediately. Dental arch dimensions were measured using digital caliper 2Caliper 63 (Mitutoyo Corporation, Kawasaki, Japan) directly on the dental casts by a single examiner. Data was analyzed using IBM SPSS program. Results: Mean of children age was (8.721). There was significant strong positive correlation between maxillary and mandibular inter-deciduous canine width measurements, and significant strong positive correlation between maxillary and mandibular inter first deciduous molars width measurements.There was significant weak positive correlation between maxillary and mandibular inter second deciduous molars width measurements, there was significant weak positive correlation maxillary and mandibular inter first permanent molar width measurements.All measurements of dimensions of girls were more deficient than boys, with significant difference between boys and girls for distance between the two mandibular first primary molars (P-value= 0.0053), significant difference for distance between mandibular inter second deciduous molars (P-value = 0.0001), significant difference for distance between the two maxillary first permanent molars (P- value=0.0123), significant difference for distance between the two mandibular first permanent molars (P-value= 0.0001)
