Dental arch dimensions in oligodontia patients.
Am J Orthod Dentofacial Orthop. 2008 Dec; 134(6):768-72.AJ

Abstract

INTRODUCTION

The aim of this study was to compare the dental arch sizes in a group of oligodontia patients with a group of age- and sex-matched untreated Class I control patients.

METHODS

Dental casts were measured of 50 oligodontia patients and 50 untreated Class I patients between 8 and 16 years old. For each subject, dental arch length and width parameters were measured in the maxillary and mandibular arches with digital calipers. The various dental arch parameters were compared between the 2 groups by using ANOVA.

RESULTS

The mean age of the subjects was 12.5 years. The average number of teeth missing in the oligodontia group was 11. The mean maxillary and mandibular arch lengths in the oligodontia group were reduced by 4.40 and 2.80 mm, respectively, when compared with the control group. The intercanine widths were reduced in the oligodontia group compared with the control group by 2.82 mm in the maxillary arch and 2.70 mm in the mandibular arch. The intermolar widths of the maxillary and mandibular arches in the oligodontia group were reduced by 3.40 and 1.80 mm, respectively, compared with the control group. These differences were statistically significant (P<0.01).

CONCLUSIONS

The findings indicate that arch length and width are reduced in oligodontia patients; this should be taken into account when planning orthodontic treatment.
