Tratamiento integral de una adolescente con dentinogénesis imperfecta tipo I / Comprehensive treatment of an adolescent with type I dentinogenesis imperfecta

La dentinogénesis imperfecta (DI) es un desorden hereditario de carácter autosómico dominante, que se origina durante la etapa de histodiferenciación en el desarrollo dental y altera la formación de la denti-na. Se considera una displasia dentinaria que puede afectar ambas denticiones con una incidencia de 1 en 6000 a 8000 nacimientos. El tratamiento del pa-ciente con DI es complejo y multidisciplinario, supone un desafío para el odontólogo, ya que por lo general están involucradas todas las piezas dentarias y afec-ta no solo la salud buco dental sino el aspecto emo-cional y psicológico de los pacientes. Objetivo: des-cribir el tratamiento integral y rehabilitador realiza-do en una paciente adolescente con diagnóstico de DI tipo I. Relato del caso: Paciente de sexo femenino de 14 años, que concurrió en demanda de atención a la Cátedra de Odontología Integral Niños de la FOU-BA derivada del Hospital "Prof. Dr. Juan P. Garrahan" con diagnóstico de osteogénesis imperfecta tipo III (OI). Nunca recibió atención odontológica y el motivo de consulta fue la apariencia estética de sus piezas dentarias. Se realizó el examen clínico y radiográfico arrojando el diagnóstico de DI tipo I asociada a OI. Conclusión: El tratamiento rehabilitador de la DI tipo I en los pacientes en crecimiento y desarrollo debe estar dirigido a intervenir de manera integral y tem-prana para resolver la apariencia estética y funcio-nal, evitar las repercusiones sociales y emocionales y acompañar a los pacientes y sus familias (AU)

Dentinogenesis imperfecta (DI) is an autosomal dominant inherited disorder that originates during the histodifferentiation stage of tooth development and alters dentin formation. It is considered a den-tin dysplasia that can affect both dentitions with an incidence of 1 in 6000 to 8000 births. The treatment of patients with DI is complex and multidisciplinary, it is a challenge for the dentist, since in general all the teeth are involved and it affects not only oral health but also the emotional and psychological aspect of the patients. Objective: To describe the comprehen-sive and rehabilitative treatment carried out in an adolescent patient with a diagnosis of DI type I. Case report: A 14-year-old female patient, who required dental attention at the Department of Pediatric Den-tistry of FOUBA and was referred from the Hospital "Prof. Dr. Juan P. Garrahan" with a diagnosis of os-teogenesis imperfecta type III (OI). The patient never received dental care and the reason for consultation was esthetic appearance of her teeth. A clinical and radiographic examination was performed, resulting in a diagnosis of DI type I associated with OI. Conclu-sion: Rehabilitative treatment of DI in growing and developing patients will be aimed at early and com-prehensive intervention to resolve esthetic and func-tional appearance, avoid social and emotional reper-cussions and accompany patients and their families (AU)

ABSTRACT Introduction: Dentinogenesis Imperfecta (DI) is a hereditary alteration that originates in the stage of histodifferentiation during odontogenesis; it represents a type of localized mesodermal dysplasia, characterized by an expressed alteration of dentin proteins. Case Report: a 6-year-old-male patient came to Antonio Briones Montoto Teaching Dentistry Clinic on December 2019; he was referred by genetics service. The diagnosis of dentinogenesis imperfecta-type II was established, of autosomal dominant character without sex predominance. Temporary teeth were rehabilitated with metal crowns, to avoid further abrasion of the teeth, performing a restoration of the masticatory function and replacement of the lost vertical dimension. Laser therapy with fluoride was applied to the present first permanent molars and lower central incisors to increase the resistance of the enamel. Conclusions: imperfect dentinogenesis type II affects the first dentition and may appear in the permanent one; based on genetic evaluation, clinical and radiological characteristics of this alteration, it is necessary to establish a precise diagnosis in order to start a timely treatment and follow-up of the patient.

Diagnóstico diferencial e conduta clínica de um cisto folicular inflamatório mandibular / Differential diagnosis and management of inflammatory follicular cyst in mandibular anterior area

Este artigo descreve a dificuldade em diagnosticar um cisto folicular inflamatório na área anterior da mandíbula em um menino com dentinogênese imperfeita tipo I (DI-1). Um menino de 6 anos de idade, com DI-1, procurou tratamento devido ao comprometimento estético. O exame radiográfico revelou uma lesão periapical envolvendo os dentes decíduos incisivo central e lateral direitos. Esses dentes foram extraídos sem intercorrências. Após três meses, a criança se queixou de dor em um edema de cor azulada na mesma área. O diagnóstico diferencial foi de cisto folicular e a lesão foi acompanhada. Como os sinais e sintomas persistiram, o tratamento de escolha foi a descompressão da lesão, seguido por irrigação abundante e curetagem das paredes da lesão. O acompanhamento clínico e radiográfico, mostrou, após 6 meses, remissão da lesão, reparo ósseo, e erupção ativa dos incisivos permanentes. As características incomuns deste caso, fizeram com que o diagnóstico de cisto folicular inflamatório fosse dificultado.

This article reports the difficulties in diagnosing an inflammatory follicular cyst in the mandibular anterior area of a boy with type 1 dentinogenesis imperfecta (DI-1). A 6-year-old boy, with DI-1, sought treatment due to esthetic complaints. The radiographic examination revealed a periapical lesion involving the right primary central and lateral incisors. These teeth were extracted with no complications. After three months, the boy complained of pain in a blue-black edema in the same area. The differential diagnosis was of follicular cyst and the lesion was followed-up. As the signs and symptoms persisted, the treatment of choice was to decompress the lesion, followed by copious irrigation, and lesion's wall curettage. After six months, the clinical and radiographic follow-up showed lesion remission, bone repair, and active eruption of permanent incisors. The uncommon characteristics of the case make the diagnosis of inflammatory follicular cyst difficult.

A histological continuum between dentinogenesis imperfecta and dentin dysplasia: A case report with literature review

Dentinogenesis Imperfecta and dentin dysplasia are genetic oral diseases inherited in a simple autosomal dominant mode, with high penetrance and a low mutation rate. Both of them are present with bulbous crowns, marked cervical constrictions, severe attritions, few periapical radiolucencies, and premature tooth loss. The diagnosis is based on family history, and detailed clinical examination, while genetic diagnosis may become useful in the future once sufficient disease-causing mutations have been discovered. Here, we present a case with overlapping features of both dentinogenesis imperfecta and dentin dysplasia asserting both the anomalies to be part of the same continuum of the genetic event.

Má oclusão em crianças e adolescentes com osteogênese imperfeita / Malocclusion in children and adolescents with Osteogenesis Imperfecta

A Osteogênese Imperfeita (OI) é uma doença genética que afeta o tecido conjuntivo e é causada por defeitos na síntese de colágeno tipo I. As alterações na produção do colágeno podem causar anomalias nos ossos da face, resultando em um crescimento craniofacial anormal e má-formação dos dentes e arcos dentários. Dentre as más oclusões, indivíduos com OI apresentam alta prevalência de mordida cruzada, mordida aberta e má oclusão de Classe III. Este estudo objetivou comparar os fatores associados com as más oclusões em crianças e adolescentes com OI e sem OI. Foi realizado um estudo transversal, pareado, com 39 indivíduos com OI e 39 sem OI, na faixa etária de três a 17 anos, e seus pais/responsáveis. A coleta de dados ocorreu por meio de um questionário direcionado aos pais/responsáveis e exame bucal das crianças e adolescentes atendidos nos setores de Ortopedia e Pediatria do Hospital das Clínicas da Universidade Federal de Minas Gerais (UFMG), em Belo Horizonte, região sudeste do Brasil. O instrumento continha itens sobre as características individuais, econômicas, hábitos comportamentais e história médica-odontológica dos filhos. O exame clínico identificou o tipo de respiração das crianças/adolescentes e a presença de anomalias dentárias, apinhamento dentário, má oclusão (mordida aberta anterior e mordida cruzada anterior/posterior) e dentinogênese imperfeita (DI). A fim de garantir a confiabilidade dos dados, foi realizado um treinamento teórico e a calibração prática dos examinadores. O treinamento teórico foi conduzido por meio de leitura sobre o tema e imagens em slides. Após essa etapa, seguindo um padrão ouro diagnóstico, foi realizada a calibração prática. Os valores kappa obtidos para cada condição examinada variaram de 0,82 a 0,96. A confiabilidade interna foi garantida por meio do testereteste do instrumento, que apresentou valores kappa entre 0,81 e 1,00. Em seguida foi realizado o estudo piloto com 5 pares de pais/responsáveis e crianças/adolescentes com OI e 5 sem OI. Após essas fases foi iniciado o estudo principal. Esta pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da UFMG. Os dados foram analisados por meio do software Statistical Package for Social Science - SPSS® (versão 21.0). A média de idade das crianças/adolescentes foi de 7,9 anos (±4,5). Ao comparar o grupo de crianças/adolescentes com OI e sem OI verificou-se uma associação estatisticamente significativa entre ter OI e ser diagnosticado com anomalias dentárias (dentes conóides, dentes fusionados/ geminados, ausência clínica, rotação e microdontia) (p=0,001) e apinhamento dentário (p=0,001). A presença de OI foi estatisticamente associada com mordida aberta anterior (p=0,043), mordida cruzada anterior (p=0,045) e mordida cruzada posterior (p=0,004). No grupo com OI, a prevalência de mordida cruzada anterior foi associada com o uso de bifosfonatos (p=0,036) e com a presença de DI (p=0,004). A presença de mordida cruzada posterior foi associada com a presença de DI (p=0,006). A mordida aberta anterior não foi estatisticamente associada com as variáveis independentes (p>0,05). Concluiu-se que a prevalência de anomalias dentárias e de má oclusão foi maior entre as crianças/adolescentes com OI. No grupo com OI, ter DI foi associado a prevalência de mordida cruzada anterior e posterior entre as crianças/adolescentes. Fazer uso de bifosfonatos foi associado a mordida cruzada anterior.

Osteogenesis Imperfecta (OI) is a rare genetic disorder which affects connective tissue and it is caused by defects in type I collagen structure or synthesis. Alterations in collagen production might cause abnormal craniofacial growth and malformation of the teeth and dental arches. Among the malocclusions, individuals with OI have a high prevalence of crossbite, open bite and Class III malocclusion. This study aimed to compare the prevalence of malocclusion in children/adolescents with OI and without OI and to identify its associated factors. A cross-sectional study was performed of 39 individuals with OI and 39 without OI, aged from 3 to 17 years, and their parents/guardians. Children and adolescents with OI and without OI were matched by sex and age. They are treated in the Orthopedic and Pediatric outpatient clinics of a university hospital, in Belo Horizonte, southeastern Brazil. The instrument contained items on the individual, economic and oral-medical characteristics of the children. The clinical examination identified the type of breathing of the children / adolescents and the presence of dental anomalies, dental crowding, malocclusion (anterior open bite and anterior / posterior crossbite) and imperfect dentinogenesis (DI). In order to guarantee the reliability of the data, a theoretical training and the practical calibration of the examiners were carried out. Theoretical training was conducted through reading on the subject and images on slides. After this step, following a gold standard diagnosis, the practical calibration was performed. The kappa values obtained for each condition examined ranged from 0.82 to 0.96. The internal reliability was guaranteed by the test-retest of the instrument, which presented kappa values between 0.81 and 1.00. Then, the pilot study was carried out with 5 pairs of parents / guardians and children / adolescents with OI and 5 pairs without OI. After these phases the main study was started. This study was approved for the Research Ethics Committee of the Federal University of Minas Gerais. The mean age of children/adolescents was 7.9 years (± 4.5). When comparing the OI group and without OI, there was a statistically significant association between having OI and being diagnosed with dental anomalies (conoid teeth, fused/geminated teeth, clinical absence, rotation and microdontia) (p=0.001) and dental crowding (p=0.001). The presence of OI was statistically associated with anterior open bite (p=0.043), anterior crossbite (p=0.045) and posterior crossbite (p=0.004). In the OI group, the prevalence of anterior crossbite was associated with the use of bisphosphonates (p=0.036) and with the presence of ID (p=0.004). The presence of posterior crossbite was associated with the presence of ID (p=0.006). The anterior open bite was not statistically associated with the independent variables (p>0.05). It was concluded that the prevalence of dental anomalies and malocclusion was higher among children / adolescents with OI. In the group with OI, having DI was associated with the prevalence of anterior and posterior crossbite among children / adolescents. Using bisphosphonates was associated with anterior crossbite.

Dentinogenesis imperfecta type II: approach for dental treatment / Dentinogênese imperfeita tipo II: abordagem de tratamento odontológico

Introduction: Dentinogenesis imperfecta (DI) is a hereditary dentin development disorder that affects both primary and permanent dentitions. The DI characteristics are discolored and translucent teeth ranging from gray to brownish-blue or amber. The enamel may split readily from the dentin when subjected to occlusal stress. Radiographically there are evident of cervical constrictions, short root and pulp chambers, and the root canals are smaller than normal or completely obliterated. The dental treatment choice can be decided on a case-by case-basis, considering the degree of dental tissue loss, and child age and cooperation. Objective: The aim of this case report was to describe the early dental treatment performed in a child affected by DI type II. Case Report: The treatment involved basic preventive procedures. Primary molars were worn to such an extent that the remained tooth structure was covered with composite resin to protect the exposed dentin. Resin-based sealant was applied in all first permanent molars. Posterior cross bite was treated with the expansion of the upper arch. Conclusion: The early treatment restored the patient´s vertical dimension resulting in acceptable esthetics and function for the permanent teeth to complete their eruption.

A escolha do tratamento pode ser decidida com base no caso, considerando-se a idade da criança, grau de perda de tecido dentário e de cooperação do paciente. Objetivo: O objetivo deste relato de caso foi descrever o tratamento odontológico precoce realizado em uma criança afetada pela DI tipo II. Relato do Caso: O tratamento envolveu procedimentos básicos de prevenção. Molares decíduos foram desgastados, de tal forma que a estrutura remanescente do dente foi coberta com resina composta para proteger a dentina exposta. Selante resinoso foi aplicado em todos os primeiros molares permanentes. Mordida cruzada posterior foi tratada com a expansão do arco superior. Conclusão: O tratamento precoce restaurou a dimensão vertical do paciente resultando em estética e função aceitáveis para os dentes permanentes completarem sua erupção.

Prosthodontic Rehabilitation of A Patient With Dentinogenesis Imperfecta.

Dentinogenesis Imperfecta is an autosomal dominant disorder of tooth development characterized by the presence of opalescent dentin, resulting in a dusky blue to brownish discoloration of the teeth. This condition is genetically and clinically heterogeneous, it may affect only the teeth or it may be associated with the Osteogenesis Imperfecta. It is inherited as autosomal dominant trait and in fact it is one of the most common dominantly inherited disorder in humans. The scalloping at the dentinoenamel junction is thought to help by mechanically interlocking the two hard tissues together. This locking is defective in these conditions which lead to enamel fracture easily from the defective dentin. The exposed dentin may then undergo severe and rapid attrition. Early diagnosis and proper treatment is mandatory in these conditions. Delay in the treatment can cause partial or complete loss of clinical crowns with healthy roots. A case report is discussed in which a young patient with Dentinogenesis Imperfecta was treated with maxillary fixed partial dentures and mandibular fibre reinforced overdentures with metal occlusal surfaces.
