Dentition status, missing teeth, and impacted teeth in patients with osteogenesis imperfecta

Main Article Content

Abstract

This cross-sectional study aimed to describe the patterns of tooth eruption, hypodontia, and impaction in patients with osteogenesis imperfecta (OI). Data were collected from 98 OI patients aged 2 - 19 years who received treatment at the National Children’s Hospital between 2018 and 2023. Clinical examinations and panoramic radiographs were used to record eruption characteristics, missing teeth, and impacted teeth. The results showed that most OI patients exhibited tooth eruption within normal limits (80%). Maxillary second molar impaction was observed in 30.8% of patients older than 14 years, a rate higher than that generally reported in the healthy population. Permanent tooth agenesis was identified in 5.9% of the patients based on panoramic imaging. In conclusion, the majority of OI patients demonstrated normal eruption patterns; however, a notable proportion presented with maxillary second molar impaction and hypodontia. Regular monitoring of dental development in this patient group is essential for early detection and timely intervention of eruption abnormalities.
