AIM: This study evaluated dimensions of the dental arches of children affected with hypophosphataemic vitamin D resistant rickets (HVDRR), since no reports are available in the literature on the effect of this disease on the dental arches. STUDY DESIGN: comparative cross sectional. METHODS: The dimensions of the dental arches of 21 Jordanian children aged 3–16 years with HVDRR were measured and compared to those of matched healthy controls, using Paired t-test at the confidence level of 95%. One examiner performed all measurements on the models in a blind manner. RESULTS: Compared with healthy controls, a significant reduction in all transverse dimensions of the maxillary arch of diseased individuals was seen. Maxillary arch depth and arch perimeter were also significantly reduced in diseased individuals (P value 0.000 0.009, respectively). In the mandibular arch, a significant reduction was found in the inter-incisor, intercanine and inter-first premolar widths in patients with HVDRR compared with normal controls (P values 0.005, 0.015 and 0.0035 respectively). Mandibular arch depth and arch perimeter were also significantly reduced. CONCLUSIONS: There is a trend towards smaller dental arches in patients with HVDRR compared with healthy controls. The results of the present study necessitate further exploration of the effect of this disease on dental arch development to improve dental management of this special need population.
