Total Idiopathic Root Resorption of Permanent Dentition

Abstract

Idiopathic external root resorption (IERR) is an infrequent pathology with few accounts in the literature. Treatment has been discussed by various authors but with no consensus. The aim of this article is to describe a new and severe case of IERR in an indigenous 21-year-old woman who came to the Dental Clinic at the Universidad de La Frontera presenting differing degrees of mobility in several teeth, which was increasing progressively with no signs or symptoms of periodontal disease and with no history of former dental treatment, dental trauma or other dentoalveolar pathology; she also did not relate any history of syndromes or systemic diseases. The panoramic x-ray showed varying degrees of external root resorption. To the best of our knowledge, only 3 cases of IERR have ever reported in the literature indicating different treatments; for this patient the treatment indicated was osseointegrated implants in the upper anterior region. Unknown etiology and treatments without consensus make research associated with genetics and molecular biology necessary. La reabsorcin radicular externa Idioptica (IERR) es un fenmeno patolgico poco frecuente, con pocos relatos en la literatura. La terapia para esta patologa ha sido discutida sin consenso por diferentes autores. El objetivo de este articulo es describir un caso severo de IERR en una mujer indgena de 21 aos de edad que concurre a la Clnica Dental de la Universidad de la Frontera debido a la presencia de diferentes grados de movilidad en varios dientes, acentundose de forma progresiva, sin signos o sntomas de enfermedad periodontal, sin antecedentes de tratamiento de ortodoncia previo, trauma dental u otra patologa dentoalveolar, ni antecedentes de sndromes o enfermedades sistmicas. La evaluacin radiogrfica con imagen panormica expone diversos grados de reabsorcin radicular externa. De nuestro conocimiento solo 3 casos de IERR han sido reportados en la literatura sealando distintos tratamientos; para esta paciente ha sido indicado el tratamiento con implantes oseointegrados en el sector anterosuperior. La etiologa desconocida y los tratamientos sin consenso, hacen necesaria la investigacin asociada a estudios de gentica y biologa molecular.
