Pediatric Molar Hyperdontia: A Descriptive Case Report.

Background: Hypergenetic molars are uncommon in children and adolescents. Furthermore, the presence of multiple eumorphic supernumerary molars (SNMs) in children is sporadic. The author, therefore, reports a nonsyndromic case of multiple supplemental SNMs in a child. Case description: A ten year old boy primarily complaining of cheek biting was found to have six molars on the maxillary left quadrant. Following investigations and case discussion, four molars and fibroma were surgically removed under general anesthesia. Discussion: This paper discusses the prevalence and management of SNMs in the pediatric population while documenting the first case of multiple eumorphic SNMs in the mixed dentition.

Impacted Molariform Distomolar Double Tooth: A Case Report.

Double teeth, also called connated or cojoined teeth, are clinically present as two separate teeth united by dentin. It occurs due to the fusion of two individual tooth buds or the partial splitting of one into two. An accessory supernumerary fourth molar is called a distomolar or distodens. Usually, the distomolar has a small crown that can be conical, peg-shaped, or like a small premolar called molariform distomolar that occurs distal to the last molar. This case presents an impacted molariform distomolar with the fusion of crown and root in a 27-year-old female.

Ghost image of an ectopic tooth in maxillary sinus: A diagnostic challenge.

Ghost images are artefacts of anatomical structures or foreign objects that oral and maxillofacial surgeons should take into consideration to prevent misdiagnosis and mistreatment. A 38-year-old male patient referred to our clinic for dental implant treatment. Orthopantomograph (OPG) revealed an impacted distomolar at the apex of maxillary right third molar and an ectopic supernumerary tooth in the left maxillary sinus. Despite the ectopic supernumerary tooth appearance on OPG, cone beam computed tomography images revealed that there was not a supernumerary tooth in the left maxillary sinus. Nasal cavity and paranasal sinuses in field of view were evaluated and maxillary ostium diameters were measured to detect if the tooth had migrated. The tooth appearance on the OPG was determined as a ghost image of the impacted distomolar at the contralateral side. Following the extraction of the distomolar, another OPG was performed and the ghost image was disappeared.

Impacted wisdom tooth in the floor of the orbit.

Identification and management of ectopic supplemental tooth in anatomically complex areas such as the floor of orbit are challenging. This arises from the rarity and lack of consensus over management. The situation gets complex when there is an evidence of follicular pathology such as dentigerous cyst. In this report, a case of maxillary third molar associated with maxillary sinus and a distomolar in association with the floor of orbit medially to the inferior-orbital canal is presented. The surgical management of the condition is presented.

Bilateral presentation of different supernumerary teeth in nonsyndromic patients: case reports.

Supernumerary teeth--teeth in excess of the normal dental complement--are usually asymptomatic, and their presence is detected incidentally on radiographs. Mesiodentes are the most common type of supernumerary teeth, followed by maxillary distomolars, maxillary lateral incisors, mandibular fourth molars, and maxillary premolars. Bilateral occurrence of supernumerary teeth is rare. When supernumerary teeth do occur bilaterally, they are most often associated with a syndrome such as Gardner syndrome or cleidocranial dysostosis. This article presents case reports of 4 nonsyndromic patients with different forms of bilateral supernumerary teeth: bilateral mesiodentes, bilateral paramolars, bilateral distomolars, and bilateral parapremolars. The supernumerary teeth were managed by extraction or clinical and radiographic monitoring.

Supernumerary teeth of permanent dentition in patients with neurofibromatosis type 1.

PURPOSE: The purpose of the study was the investigation of supernumerary teeth (ST) in the permanent dentition of patients with neurofibromatosis type 1 (NF1). MATERIAL AND METHODS: The panoramic radiographs of 200 NF1 patients were analysed for ST. The potential impact of certain neurogenic facial tumours on the measured variable was investigated separately. The results were compared to dental findings in panoramic radiographs of 200 age- and sex-matched controls. RESULTS: The total number of ST in all individuals was 23 in 12 patients (3% of total population). However, all ST had developed in the group of NF1 patients (6%), (p = 0.0004). ST were particularly common distal to the molar region. Although ST occur in the region of facial plexiform neurofibroma, the numerical aberrations of the dentition are independent of specific type of facial nerve sheath tumour. CONCLUSION: The unusual accumulation of ST in the terminal sections of molar development could be an indicator of preferred points of developmental disorder, in which the genetic predisposition of the patient is involved. Reviewing the results of other NF1 patient collectives is desirable.

Distomolares en posición ectópica (kissing molars): reporte de un caso / Distomolars in ectopic position (kissing molars): report of a case

Introducción: El término kissing molars se traduce como «dientes besándose¼; superfi cies oclusales de dos molares retenidos están en contacto una con otra en espacio folicular único y raíces en dirección contraria. Literatura científi ca ha reportado 44 casos. Cuartos molares o distomolares, supernumerarios que se forman distalmente a terceros molares; tamaño y forma variable, generalmente retenidos. Caso clínico: Femenino de 32 años con molestias en zona retromolar inferior izquierda, limitación de apertura, trismus, disfagia. En ortopantomografía, se observa cuarto molar retenido junto con tercer molar, superfi cies oclusales de ambos órganos dentarios retenidos en íntimo contacto dentro de un mismo saco folicular, raíces en dirección opuesta. Discusión: Existe controversia acerca de diferencia entre molares retenidos y KM, algunos autores sugieren que la ausencia de contacto entre dos molares retenidos no permite incluirlos en esta condición. Etiología aún incierta, algunos lo consideran como un evento aislado. Existe una teoría en relación con la formación de quiste dentígero; resorción ósea causada por presencia y expansión de éste, resulta en pérdida de hueso en zona mesial de molares retenidos facilitando movilización, inclinación y contacto uno con otro (AU)

Introduction: The term kissing molars is used when the occlusal surfaces of two retained molars are in intimate contact inside the same follicular sack and roots in opposite direction. Literature has reported 44 cases. Fourth molars, also known as distomolars, are a supernumerary tooth that grows distally to third molars; size and shape are variable, generally retained. Case report: Female 32 years old, pain in the left inferior retromolar zone, trismus, dysphagia. Fourth and third retained molars, with occlusal surfaces in contact, inside the same follicular sack, roots in opposite direction are observed in orthopantomography. Discussion: There is controversy about the diff erence between retained molars and KM, some authors suggest that the absence of contact between two retained molars, does not allow to include them in this condition. Etiology still unknown. Dentigerous cyst formation theory is proposed due to the bone resorption in the mesial zone of retained molars in this entity, which facilitates mobilization and contact between molars (AU)

Presencia del cuarto molar. Revisión de la literatura / Presence of the fourth molar. Literature review

Resumen: El cuarto molar, también llamado distomolar, es una variante de número y forma que se presenta como una alteración durante la odontogénesis, pueden ser eumórfico o dismórfico, único o múltiple, erupcionado o retenido, de forma unilateral o bilateral y se puede presentar en ambos maxilares. La etiología es desconocida, pero existen varias teorías que justifican el desarrollo de esta alteración dentaria como la duplicación de la lámina dental, su proliferación horizontal o hiperactividad de ésta; otros factores pueden ser los hereditarios, la división completa del germen dentario o regresión filogenética. El cuarto molar se encuentra en un espacio muy importante, que al desconocer su existencia o técnica adecuada para su extracción, las posibilidades de tener severas complicaciones transy postoperatorias son altas. Se realiza una revisión bibliográfica de diferentes artículos y textos en diferentes años para determinar de forma más clara el origen y formación de este diente supernumerario.

Abstract: Fourth molars, also called distomolars, are a variant in shape and number appearing as alterations during odontogenesis. They can be eumorphic or dismorphic, single or multiple, erupted or impacted, unilateral or bilateral, and can appear in both jaws. They are of unknown etiology, but there are several theories to justify these tooth alterations such as dental lamina duplication, its horizontal proliferation or its hyperactivity. Other factors can be hereditary factors, full division of tooth bud or phylogenetic regression. Fourth molars are found in a very important space, and when their own existence or the suitable extraction techniques are unknown, severe complications can frequently occur during and after surgery. A literature review was undertaken, examining different articles and texts of different years, in order to better determine the origins and formation of this supernumerary tooth.

Dientes supernumerarios en la región del tercer molar inferior: etiología y manejo quirúrgico: presentación de dos casos / Supernumerary teeth in the lower third molar region: etiology and surgical management: report of two cases

Los dientes supernumerarios en la región del tercer molar inferior sonpoco frecuentes. Cuando se presentan en posición distal se les denominadistomolares o distodens. Algunos autores los denominan cuarto molar; ésta denominación es la menos aceptada, ya que el cuarto molarno forma parte de la fórmula dental permanente, sino que es un dientesupernumerario. Cuando éste se presenta paralelo a los molares, en lacara externa o interna de la mandíbula, se denomina paramolar. El manejo quirúrgico suele ser complejo y requiere consideraciones especiales. Presentamos dos casos de dientes supernumerarios en la región del tercer molar: distomolar y paramolar; describimos su diagnóstico, etiología y la técnica quirúrgica empleada.

Supernumerary teeth in the lower third-molar region are rare. When these are located in the region posterior to the third molar, they are known as ®distomolars¼ or ®distodens¼. Some authors refer to them as ®fourth molars¼, a term that is somewhat less accepted due to the fact that the fourth molar is not part of the permanent dentition, but rather a supernumerary tooth. When a distomolar occurs parallel to the molars, either on the outer or inner surface of the jaw, it is known as a ®paramolar¼. Surgical management is often complex and requires special considerations. We report two cases of supernumerary teeth in the third-molar region, one distomolar and one paramolar, and describe their diagnosis, etiology, and the surgical technique employed.

Prevalence and characteristics of non-syndromic distomolars: a retrospective study.

AIM: Distomolars are defined as the supernumerary teeth that erupt distal to the third molar. The aim of the present study was to evaluate the prevalence of distomolars in permanent dentition in a non-syndromic Turkish subpopulation. METHODS: A total of 10 111 panoramic radiographs of patients aged 18 years and over, who had no systemic diseases and syndromes, and who had not undergone any extractions in the third molar area, were examined to determine the presence, location, shape, and laterality of distomolars. The patients' age and sex were noted. RESULTS: The results showed that distomolars were observed in 0.26% of the investigated population. Distomolars were seen in 0.29% of male patients and in 0.23% of female patients. In total, 30 distomolars were observed in 26 patients. Maxillary distomolars were more frequently encountered than mandibular teeth. Bilateral distomolars were found in three male patients. Of the 30 distomolars, 25 were impacted and five were erupted. CONCLUSIONS: Although the frequency of distomolars is low, early diagnosis and treatment are important to minimize or prevent complications, such as delayed eruption, tooth displacement, crowding, root resorption of the adjacent tooth, and cystic formations.

Quarto molar retido nos quatros quadrantes: revisão da literatura e relato de caso / Fourth molar restrained in four quadrants: revision of literature and describe a case

A presença de um ou mais dentes excedentes nas arcadas superiores e inferiores são chamados de dentes supranumerários. A razão pela qual isto ocorre ainda não está completamente entendida, porém acredita-se ser consequência de uma hiperatividade da lâmina dentária. Ocorre na maioria dos casos na dentição permanente, com maior prevalência no sexo masculino. Estes dentes podem gerar alterações como falhas no inrrompimento dos dentes adjacentes, cistos e tumores odontogênicos além de deslocamento dentário. São classificados por sua forma e localização. Na maioria dos casos são assintomáticos e são descobertos através de exames radiográficos de rotina. Este trabalho tem por objetivo realizar uma breve revisão da literatura e relatar um caso onde o paciente possuía quatro supranumerários tanto em maxila como mandíbula, removidos cirurgicamente

The presence of one or more teeth exiting in the superior and inferior arcade is known as supernumeraries’ teeth. The reason which this occurs is not complete understudied so far, however it believes to be a consequence of a hyperactivity of the lamina dental. Occur in the majority of the cases in permanent teeth, with predominant in males. These teeth can generate alterations like faults interruptions of the adjacent teeth, cyst and odontogenics tumors including dentary dislocation. They are classifying in your way of location. In the majority of the cases they are symptoms free and are found through the routine radiography exams. This aim of this study is to realize a brief literature revision and describe a clinical case where a patient had supernumeraries in the chain, surgical remove
