“…In other countries, case reports concerned smaller cohorts. [9131415] A study on Indian population had a prevalence rate of DI of 0.09%; their results consisted of only one affected individual who was a male. [3] Therefore, gender difference could not be evaluated.…”

Background:Dentinogenesis imperfecta is a genetic disorder of the dentin occurring during the tooth development. It leads to many structural changes that can be identified clinically (brownish colored teeth, cracked enamel) and radiologically (globular crown, cervical constriction, short roots, and obliterated pulp chamber and/or root canals). The aim of this study was to determine by panoramic radiographs assessment the incidence of dentinogenesis imperfecta in a group of patients attending a specialized maxillofacial imaging center in Paris, France.Material and Methods:A retrospective observational study was conducted using panoramic radiographs of 8830 patients (3723 males and 5107 females), which were used to search the radiological criteria of dentinogenesis imperfecta.Results:In our sample, the prevalence of dentinogenesis imperfecta was 0.057%. Out of the 8830 subjects, 0.080% of the males presented the radiological signs of the dentinogenesis imperfecta against 0.039% of the females.Conclusion:In our study, we found that dentinogenesis imperfecta is a relatively rare dental anomaly in France, with a rate different from the rates reported in other studies and with no disparity in prevalence among genders.

“…The absence of teeth influences the aesthetics and masticator function with consequent impairment in the quality of life of the patient5. Dentin dysplasia is a rare condition, with a complex diagnosis, and the need for evaluation and interdisciplinary planning [8]. The differential diagnosis of DDI is made with dentinogenesisimperfecta, aware autosomal dominant condition, at which teeth may exhibit color changes, hypo mineralized and exposed dentin, bulbous crowns, cervical constriction, thick and short roots and obliteration of the pulp chamber [2].…”

This paper aims to report the case of a child with dentin dysplasia type I. An 8 year old female child was referred to the Children's Dental Clinic of the Universidade Federal do Piauí with an aesthetic complaint caused by missing teeth. Four permanent first molars, premolar upper right and upper left permanent canine were present. There was satisfactory oral hygiene and no dental diseases. Anamnesis and laboratory tests did not detect any systemic disorders. Evaluations of initial panoramic radiographs and computed tomography showed permanent teeth with apparently normal crowns, with short and conical roots and obliteration of the pulp chamber, confirming the diagnostic hypothesis of Dentin Dysplasia type I. Root Dentin Dysplasia or Dentin Dysplasia type I is a rare hereditary autosomal dominant disorder, with a complex diagnosis, and the need for evaluation and interdisciplinary planning. There is no specific treatment for this genetic condition. Temporary mucosa-supported prosthesis reimbursed with resilient resin was made to preserve the sites of erupted teeth and those erupting. Monitoring is to be done until the growth of the facial structures is completed, allowing for rehabilitation with fixed prostheses on implants.

“…Unlike MIM, this condition is hereditary and is also called "rootless teeth". 20,21 Dentinal disorganization can happen at different stages of tooth development, which can vary from one patient to another and from tooth to tooth in the same patient. The most affected were deciduous teeth and, in permanent teeth, it depends on the proportion of dentin between organized and disorganized dentin.…”

Introdução: "Malformação molar-incisivo" (MIM) ou "Malformação radicular molarincisivo" é uma anomalia dental recém-reportada de etiologia desconhecida, possivelmente associada a complicações sistêmicas, que afeta o desenvolvimento de raízes dos primeiros molares permanentes e esmalte dentário de incisivos centrais. Objetivo: Realizar uma revisão da literatura sobre "Malformação molar incisivo", também conhecida como "Malformação raiz-molar incisivo", discutindo seus aspectos clínicos, radiográficos/tomográficos, diagnóstico diferencial e possibilidades de tratamento. Fonte dos dados: Busca eletrônica foi realizada na base MEDLINE, em março de 2021, sem limite quanto ao ano de publicação. Os termos pesquisados foram "molarincisor malformation", "molar-root incisor malformation", "root malformation", "root development", "tooth roots", "abnormalities". Síntese dos dados: Quinze artigos, na maioria série de casos, foram incluídos. Em geral, a história médica revelou complicações clínicas durante a gestação e/ou primeiros anos de vida. As características clínicas incluíram defeitos de esmalte dentário na região cervical de incisivos e mobilidade acentuada de molares e incisivos permanentes. Radiograficamente, observou-se a presença de câmaras pulpares parcialmente obliteradas, raízes de molares e incisivos permanentes curtas, finas e incompletas. Microscopicamente, reportou-se a ocorrência de camada de dentina hipercalcificada, em forma de lente, no interior da câmara pulpar, ao nível da junção cemento-esmalte, denominada de "diafragma cervical mineralizado". Conclusão: A "Malformação molar-incisivo" é uma anomalia caracterizada por alterações do desenvolvimento radicular, da câmara pulpar e do esmalte em molares e incisivos permanentes. O diagnóstico diferencial inclui Displasia dentinária tipo I e Odontodisplasia regional. Históricos médico e familiar são essenciais para o diagnóstico final, e o tratamento, o qual apesar de não ter protocolo estabelecido requer abordagem multidisciplinar e tratamentos convencionais como exodontia, endodontia, ortodontia e implantes dentários.
