Relationship between the stage of tooth development and body development in a precocious puberty girl

Objectives: Precocious puberty is associated with abnormal development and especially altered development of the teeth. We conducted a case-control study between March 2014 and March 2015 to evaluate tooth development in children with precocious puberty. Methods: The patient group consisted of 55 girls who were diagnosed with precocious puberty in the pediatrics department of a university hospital and underwent no more than one round of medication. The control group consisted of 55 typically developing children who visited a dental clinic and were age-matched to participants in the patient group. Both the patient and the control group were subjected to panoramic radiography, while sexual maturity, bone age, and sex hormones were evaluated in the patient group. Results: 1. A later calcification developmental stage of the canines, 1 st premolars, 2 nd premolars, and 2 nd molars was associated with a higher rate of inclusion in the patient group. 2. In the patient group, there was a significant association between bone age and developmental stage for all evaluated teeth (p<0.01). Conclusions: The above results demonstrate a particular need for oral healthcare in girls with precocious puberty and prioritization of tooth health in their dental care.
