Abstract

Background Osteogenesis imperfecta (OI) is the collective term for a heterogeneous group of connective tissue syndromes. The aim of the current study is to describe dental characteristics, including dentinogenesis imperfecta (DGI), dental wear, occlusal features, and dental caries experience of Vietnamese persons with OI.
Methods The sample consisted of 74 individuals with OI classified into type I (n=25), type III (n=24), and type IV (n=25). All participants were examined for DGI through the evaluation of intrinsic color variation, dental wear using Hooper’s index, occlusal features (including Angle’s classification, overjet, overbite, crossbite) and dental caries experience by using the dmft/DMFT index.
Results DGI was found in 62.2% of the sample and was significantly related to OI type III and type IV (p=0.019). Dental wear occurred in 36.5% and was equivalent among OI types. Angle Class III malocclusion was more prevalent in type III (66.7%) and type IV (54.5%) than in type I (37.5%). High prevalence of reverse overjet (60.3%), posterior crossbite (32.2%), and missing teeth (23.3%) were found in the OI sample. The mean dmft/DMFT score was 3.0/2.2. The dental findings related to dental wear, occlusal features, and dental caries did not show significant differences among type I, III, and IV.
Conclusion There was a high prevalence of DGI and dental wear in the Vietnamese OI sample. Occlusal features were related to a high prevalence of class III malocclusion, overjet, open bite, posterior crossbite, and missing teeth. Dental caries experience of persons with OI was at a moderate level.
