Abstract

Objectives: To identify unique characteristics of the craniofacial complex and dental maturity in girls with central precocious puberty (CPP). Materials and Methods: This study included 34 Korean girls with idiopathic CPP (mean age, 8.6 6 .5 years) and 28 normal healthy girls of the same chronological age. An initial evaluation of the growth pattern of the craniofacial complex and dental maturity was conducted by analyzing lateral cephalometric and panoramic radiographs. Results: The mandibular ramus height (44.4 6 4.1 mm) and total mandibular length (10.8 6 4.3 mm) (P ¼ .004 and .021, respectively) were greater and the lower anterior facial height was lesser (63.2 6 2.4 mm) (P ¼ .040) in the CPP group than in the reference group. In addition, the gonial angle (12.9 6 6.18; P ¼ .045) and the mandibular plane angle (34.9 6 4.88; P ¼ .012) were smaller in girls with CPP than in normal healthy girls. All the mandibular teeth were more mature in girls with CPP (P, .001). A strong positive correlation was observed between the mandibular tooth formation stages and the presence of CPP in girls (r ¼ .756 to .957; P, .001). Conclusions: CPP had an effect on the anteroposterior growth of the mandible in the craniofacial complex and the rotation of the mandibular plane angle. Early maturation of the mandibular teeth was observed in girls with CPP.
