ABSTRACT
Introdução: a epidermólise bolhosa compreende um grupo de doenças genéticas e raras da pele, onde há uma fragilidade estrutural da pele e das mucosas. A gravidade das manifestações clínicas varia de acordo com o subtipo envolvido, no qual a citada enfermidade distrófica recessiva é a mais severa. Há várias implicações sistêmicas, como a anemia, a desidratação e a desnutrição. O envolvimento bucal acompanha e torna mais severo o comprometimento sistêmico. As alterações em tecidos moles e duros dessa região variam consideravelmente. São relatados atrasos no crescimento e desenvolvimento dentoesquelético. Objetivo: considerando as possíveis alterações de desenvolvimento, este estudo tem o objetivo de mensurar a idade dentária em pacientes com epidermólise bolhosa distrófica recessiva, verificando a acurácia de dois métodos em relação à idade cronológica. Metodologia: foi realizado um estudo descritivo analítico transversal do tipo série de casos, que avaliou a idade dentária de 10 pacientes pelos métodos de Demirjian e Willems. Resultados: não houve divergência significativa entre as idades dentária e cronológica, com superestimação comum aos métodos utilizados. Conclusão: sugere-se que o tempo de maturação dentária pode ser um parâmetro estável frente a fatores adversos ao desenvolvimento, que são comuns a esse grupo. São necessários estudos que avaliem também outras variáveis para melhor compreender a relação da epidermólise bolhosa com o desenvolvimento dentoesquelético.
Introduction: Epidermolysis Bullosa (EB) describes a group of rare genetic skin diseases where there is structural fragility within the skin and mucosa. Severity of clinical manifestations varies according to the specific EB type, and the most severe EB type is recessive dystrophic EB. There are several systemic implications, such as anemia, dehydration and malnutrition. There are also oral manifestations, so systemic manifestations may be more severe. Changes in soft and hard oral tissues vary considerably. Dentofacial growth and development retardation is reported. Aim: considering developmental changes, this study aims to measure the dental age of patients with recessive dystrophic EB by verifying the accuracy of two methods in relation to chronological age. Methods: a descriptive cross-sectional and analytical study of case series was carried out, which assessed the dental age of 10 patients using Demirjian and Willems methods. Results: there was not significant divergence between dental and chronological ages, but there was mutual overestimation related to both methods. Conclusion: it is suggested that dental maturation period may be a stable parameter against adverse developmental factors that are common to this group. Studies that also assess other variables are necessary to better understand the relation between EB and dentofacial growth.

Root fractures vary in severity, extent, and location, according to the physical and mechanical aspects of the accident. Root fractures are rare in primary teeth and they affect dentin, cementum, periodontal ligament and the pulp. This paper reports a case of a two-and-a-half-year-old baby who had a root fracture of the upper right primary central incisor (tooth 51) as a consequence of trauma that was managed with minimally invasive intervention. After clinical and radiographic examinations, the presence of tooth mobility, pain, bleeding and a horizontal apical root fracture was diagnosed on tooth 51. The treatment of choice was splinting for 120 days, which can deliver excellent results regardless of the patient's age. The tooth was preserved without needing endodontic intervention until its physiologic exfoliation and normal eruption of its permanent successor. As sequelae to the fractured tooth 51, there was some coronal color alteration and dystrophic calcification of the root canal. This tooth did not develop ankylosis or mobility during the follow-up period. After 57 months of follow-up, repositioning and splinting were appropriate ways to manage this horizontal root fracture in the apical third of this primary tooth. It allowed the tooth to be preserved in the arch with normal function.
