Multidisciplinary Management and Long-Term Follow-up of Mesiodens: A Case Report

Abstract

Supernumerary teeth are relatively common in the oral cavity and are characterized by an excessive number of teeth. The term "mesiodens" refers to a supernumerary tooth located in the midline of the maxilla between the central incisors. Mesiodens may cause a variety of pathological complications such as impaction of the maxillary central incisors, tooth retention or delayed eruption of the permanent incisors,crowding, eruption within the nasal cavity, formation of diastema, intraoral infection, root anomaly, root resorption of adjacent teeth and cyst formation accompanied by bone destruction. Therefore it is recommended to follow-up with regular radiographic examination. Early diagnosis minimizes treatment needs and prevents associated complications. The present case, followed for 7 years, presented bilateral mesiodens resulting in delayed eruption of the permanent incisors and emphasizes the importance of multidisciplinary management and long-term follow-up.

Inverted mesiodens: case report

“…Of these, almost half is found in the anterior region with the prevalence of 15% to 1.9% 11 . Among the possible causes for this positioning are the cleft palates, tumors, trauma, cleft lip, malformation and genetic factors 8 , which in the shown case were not confirmed in the anamnesis and in the clinical exams carried out. Some studies associate the alteration in the regular number of teeth to the phylogenetic reversion and hyperactivity of the dental lamina 7 and also with dichotomy of a tooth germ 6 .…”

“…The combination of genetic factors can also influenciate this anomaly 3,[7][8][9][10] . The studies have shown that there is a connection in the occurrence of mesiodens with the gender, which occurrs twice more in males than in females 2-3,6-7,11-12 .

Variaciones clínicas de los mesodientes dobles: revisión y reporte de casos

“…When they do not erupt, they interfere with the eruption of permanent teeth, which may cause malocclusions. 10,35,36,37 Multiple mesiodens are less likely to erupt. 32,33,34 The purpose of this article is to describe three patients with rare cases of double maxillary mesiodens.…”

“…25,34 El tiempo que se toma para la erupción del diente permanente, una vez se ha realizado la exodoncia del diente supernumerario, varía entre seis meses y tres años. 10,34,35 Los factores que influyen en la erupción son: el tipo de diente supernumerario, núme-ro de dientes supernumerarios, la distancia de desplazamiento del diente permanente por erupcionar, ángulo de impactación con relación a la línea media, cantidad de formación radicular del diente permanente, estado de desarrollo radicular del diente supernumerario y el espacio disponible en la arcada para la erupción del diente permanente sin erupcionar. 27,30,33 …”

“…Cuando no erupciona se crea una interferencia para la erupción de los dientes permanentes, lo cual puede causar mal oclusiones. 10,35,36,37 Es menos probable que los mesodientes erupcionen cuando son múltiples. 32,33,34 El propósito de este artí-culo fue presentar a tres pacientes que presentaron tres casos infrecuentes de mesodientes dobles en el maxilar.…”
