Dentinogénesis imperfecta: a propósito de un caso

2018 
La dentinogenesis imperfecta (DI) es una anomalia hereditaria que afecta la dentina de una o ambas denticiones. Como la DI tipo I se relaciona con osteogenesis imperfecta, ante un nino con DI, el odontopediatra siempre debe estar alerta y descartar esta posibilidad. Las caracteristicas orales en ninos con DI incluyen fracturas del esmalte, atricion dental severa, sensibilidad, molares con coronas bulbosas que dificultan las restauraciones tradicionales y en algunos casos exposiciones pulpares e infecciones periapicales. El manejo terapeutico incluye la instauracion de medidas preventivas precoces y un tratamiento restaurador para evitar las atriciones y la perdida de dimension vertical. Asimismo, las implicaciones esteticas pueden tener una importante repercusion en el desarrollo psicosocial de los ninos con DI. El objetivo de este articulo es hacer una revision bibliografica actualizada sobre la DI y presentar un caso clinico en un paciente de 5½ anos.(AU) Dentinogenesis imperfecta (DI) is a hereditary disorder characterized by abnormal dentine structure affecting either the primary or both the primary and secondary dentitions. Dentinogenesis imperfecta type I is inherited with osteogenesis imperfecta (OI), for this reason pediatric dentistry must always be alert and to discard this possibility in a child with DI. The oral characteristics in children with DI include breaks of the enamel due to the underlying dentinal defect of mineralization, severe dental attrition, sensibility, molars with bulbous crowns with marked cervical constriction that make the traditional restorations difficult and in some cases pulp exposures and periapical infections. The therapeutic treatment includes the establishment of early preventive measures and a treatment to avoid the attritions and the loss of vertical dimension. Also, the aesthetic implications can have an important effect in the psychosocial development of the children with DI. The aim of this article is to do a bibliographical updated review on DI and to present a clinical case in a patient of 5½ years old.(AU)
