The oral health status and dental treatment needs of children affected by osteogenesis imperfecta – part I

Abstract

Introduction. Osteogenesis imperfecta is an inherited disorder of the connective tissue. Which in most cases, is caused by mutations in the genes encoding collagen type I. Apart from clinical features, there are characteristic dental aberrations. Aim. The purpose of this research was the assessment of the condition of teeth and therapeutic needs of children with the congenital brittle bone disease. Material and methods. The questionnaires with patient’s parents, consisting medical history and dental history were performed. The intra-oral examination included the condition of the dentition, the presence of dentinogenesis imperfecta, malocclusion, the assessment of the attrition index and dmft/DMFT index. Results. 62 patients with osteogenesis imperfecta were examined – 32 boys and 30 girls. There were normal eruption times of deciduous (48 patients – 77.42%) and permanent teeth (34 patients – 82.93%) reported in the majority of the patients with OI. In most cases bad eating and hygienic habits were observed. Dentinogenesis imperfecta in deciduous and permanent teeth was reported mostly in type III of OI. dmft/DMFT index among children with OI were low in comparison to the population studies of corresponding age groups. Conclusions. Despite bad eating and hygienic habits as well as pathological structure of dentition of patients with the congenital brittle bone disease, caries index among these children were low in comparison to the population studies of corresponding age groups.
