OSTEOGÊNESE IMPERFEITA ASSOCIADA À DENTINOGÊNESE IMPERFEITA: RELATO DE CASO

Abstract

Osteogenesis imperfecta, also known as "brittle bone disease," is a hereditary condition resulting from alterations in the formation or quantity of type I collagen. This article aims to describe the dental care provided to a child with osteogenesis imperfecta associated with dentinogenesis imperfecta. A 3-year-old male patient presented to the pediatric clinic with a chief complaint of "toothache." Physical examination revealed short stature, motor impairment, and marked bowing deformities of the lower limbs. Intraoral examination showed geographic tongue, carious lesions on primary molars, and teeth with altered coloration (blue-gray hues) and a translucent appearance, consistent with a diagnosis of dentinogenesis imperfecta. Radiographic examination revealed bulbous crowns and cervical constriction at the cemento-enamel junction. The treatment plan included restoring the carious teeth and applying infrared laser photobiomodulation at 1 J. This case demonstrates the importance of multidisciplinary follow-up and long-term planning, reinforcing the dentist's role in promoting oral health and quality of life for patients with osteogenesis imperfecta. Dental alterations not only compromise aesthetics and function but can also negatively affect these individuals' quality of life and self-esteem. Therefore, dental care must be preventive, conservative, and tailored to the patient's specific needs.
