Oro-maxillofacial development in patients with GH deficiency and in normal short children.

Abstract

Detailed oro-maxillofacial studies using dental cast, pantomogram and cephalogram were performed in 43 patients with GH deficiency aged 7-17 years and compared statistically to the results from 62 short children with normal GH secretion. The dental age was retarded as compared to the chronological age in patients with GH deficiency by a mean of 2.0 +/- 1.3 years. This value did not differ statistically from that observed in normal short children (1.7 +/- 0.8 years). However the bone age was significantly retarded in patients with GH deficiency (3.2 +/- 1.7 yrs vs 1.5 +/- 1.1 yrs, p less than 0.001). There was no difference between tooth size or cephalogram analysis results in the children in the two groups. The coronal arch length, basal arch width and basal arch length were shorter in patients with GH deficiency. These data indicate underdevelopment of the maxilla in patients with GH deficiency.
