ABSTRACT

The calcifying epithelial odontogenic tumor is a rare benign neoplasm that accounts for approximately 1% of all odontogenic tumors. Most of the cases occur in the posterior mandible, and a few involve the maxilla. Despite their relatively indolent biological behavior, tumors in the maxilla tend to grow fast. We report the case of a 33-year-old female patient exhibiting swelling in the right maxilla. An isodense area associated with an impacted supernumerary tooth was found on imaging examination. The histopathologic diagnosis was a calcifying epithelial odontogenic tumor. The treatment of choice was surgical removal of the lesion and associated dental elements. The patient has been followed up for 11 months and shows no signs of recurrence. Besides describing this case, we reviewed the literature on the association of calcifying epithelial odontogenic tumors with supernumerary teeth and found two case reports addressing this subject.

ABSTRACT

Introducción: La falta de un incisivo permanente no solo genera un efecto adverso en la estética facial, también altera la función, en especial, la guía incisiva. Los incisivos superiores pueden sufrir bloqueo mecánico o cambio en su erupción por un diente supernumerario, un golpe u otro factor. El tratamiento de elección es el quirúrgico-ortodóncico. El pronóstico dependerá de la edad, situación, posición del diente, morfología, tamaño, maduración radicular y método de tracción. Conocer el uso de una aparatología ortodóncica que sea fácil de manipular y pueda ser usada desde edades tempranas servirá de valioso aporte. Objetivo: Mostrar el uso exitoso de un cantiléver para traccionar ortodóncicamente un incisivo impactado en posición horizontal. Presentación del caso: Paciente de 8 años con maloclusión clase I, pieza 2.1 retenida en posición horizontal, presencia de supernumerario y persistencia de pieza 6.1. Se opta por extracción de supernumerario, liberación de pieza 2.1 y tracción ortodóncica. Se usó un cantiléver por vestibular confeccionado en arco de acero redondo 0.020" con dos círculos en cada extremo para brindar elasticidad y anclaje. La fuerza utilizada fue de 70 g, pasado 6 meses se alcanzó el plano de oclusión. Se cementaron brackets y tubos, se continuó con la secuencia de arcos, hasta llegar al arco acero 0.021"x0.025" durante 11 meses. Se obtiene una posición final óptima que favorece la formación radicular y cierre apical. Conclusiones: El uso del cantiléver para el tratamiento ortodóncico de incisivos permanentes impactados en posición horizontal demostró ser exitoso, fácil de manipular y controlar(AU)


Introduction: The lack of a permanent incisor not only generates an adverse effect on facial aesthetics but also alters its function, especially the incisor guidance. Upper incisors can suffer mechanical blockage or change in their eruption due to a supernumerary tooth, a blow or another factor. The treatment of choice is orthodontic-surgical. The prognosis depends on the age, tooth position, morphology, size, root maturation and traction method. Knowing the use of an orthodontic appliance, which is easy to handle and can be used from an early age, will be of valuable contribution. Objective: To show the successful use of a cantilever to enable orthodontic traction of an impacted incisor in a horizontal position. Case presentation: Eight-year-old patient with class I malocclusion, specimen 2.1 retained in a horizontal position, presence of supernumerary tooth and persistence of specimen 6.1. Extraction of the supernumerary, release of specimen 2.1 and orthodontic traction is chosen. A buccal cantilever made of a 0.020" round steel arch with two circles at each end was used to provide elasticity and anchoring. The force used was 70 g. Six months after, the occlusion plane was reached. Brackets and tubes were cemented and the sequence of arches was continued until the 0.021"x0.025" steel arch was reached in 11 months. An optimal final position is obtained, favoring root formation and apical closure. Conclusions: The use of the cantilever for orthodontic treatment of impacted permanent incisors in a horizontal position proved to be successful as well as easy to manipulate and control(AU)

ABSTRACT

Durante a formação dentária, distúrbios de desenvolvimento podem acontecer, causando anomalias de número, forma, tamanho, estrutura e posição, além de apresentarem anormalidade no padrão sequencial de irrupção. Uma boa anamnese, associada a palpação e exames de imagens são indispensáveis para um diagnóstico precoce e favorável destas alterações. Os exames de imagem determinarão a relação espacial destes dentes com as estruturas nobres adjacentes. O objetivo deste trabalho é relatar a presença de supranumerário unilateral e impactação bilateral de caninos permanentes, ambas anomalias com proximidade da cavidade nasal e seio maxilar, ressaltando a importância do diagnóstico preciso através de exames clínico e de imagens, que direcionam o planejamento terapêutico específico para cada caso, bem como a associação multidisciplinar para obtenção de um resultado satisfatório do quadro e melhora da qualidade de vida do paciente(AU)


During dental formation, developmental disorders can occur, causing anomalies of number, shape, size and position, in addition to presenting abnormality in the sequential pattern of irruption. Anamnesis associated with palpation are indispensable for an early diagnosis of these alterations. Imaging exams will determine the spatial relationship between these teeth and the adjacent noble structures. The aim of this study was to report the presence of unilateral supernumerary and bilaterally impacted canines, both anomalies with proximity of nasal cavity and maxillary sinus, emphasizing the importance of accurate diagnosis through clinical and imaging exams, that direct the specific therapeutic planning for each case, as well as the multidisciplinary association to obtain satisfactory results and improve the life quality of patients(AU)

ABSTRACT

Los dientes supernumerarios y la fusión dental son anomalías del desarrollo dental cuyas causas aún no se han dilucidado con certeza. El cuarto molar inferior, también denominado distomolar, es uno de los dientes supernumerarios con menor frecuencia de aparición clínica y su fusión con el tercer molar es una condición todavía menos común. A continuación, se reportan los casos clínicos de tres pacientes masculinos que presentaron fusión del tercer molar inferior derecho con un distomolar tratados mediante odontectomía (AU)


Supernumerary teeth and dental fusion are abnormalities of dental development whose causes have not yet been elucidated with certainty. The lower fourth molar, also called distomolar, is one of the supernumerary teeth with the least frequency of clinical appearance and its fusion with the third molar is an even less common condition. Next, the clinical cases of three male patients who presented fusion of the right lower third molar with a distomolar treated by odontectomy are reported (AU)

ABSTRACT

ABSTRACT Introduction: Supernumerary teeth in cases of cleft lip and palate do not result from the division of normal germs before the formation of hard tissue. Deciduous and permanent teeth odontogenesis begins after the face has formed, either with or without the cleft. Discussion: The most acceptable hypothesis to enable understanding of the presence of supernumerary teeth on one or both sides of the cleft palate is hyperactivity of the dental lamina in its walls. This hyperactivity, with the formation of more tooth germs, must be attributed to mediators and genes related to tooth formation, under strong influence of local epigenetic factors, whose developmental environment was affected by the presence of the cleft. Conclusion: The current concepts of embryology no longer support the fusion of embryonic processes for the formation of the face, but rather the leveling of the grooves between them. All human teeth have a dual embryonic origin, as they are composed of ectoderm and mesenchyme/ectomesenchyme, but this does not make it easy for them to be duplicated to form supernumerary teeth.


RESUMO Introdução: Os dentes extranumerários nas fissuras labiopalatinas não são resultado da divisão dos germes normais antes da formação do tecido duro. A odontogênese dos decíduos e permanentes inicia-se depois de formada a face, com ou sem fissuras. Discussão: A hipótese mais plausível para compreender a presença dos dentes extranumerários em um ou nos dois lados da fissura labiopalatina é a hiperatividade da lâmina dentária em suas paredes. Essa hiperatividade, com formação de mais germes dentários, deve ser atribuída aos mediadores e genes relacionados à formação dos dentes, sob forte influência de fatores epigenéticos locais, cujo ambiente de desenvolvimento foi afetado pela presença da fissura. Conclusão: Os conceitos atuais da embriologia não fundamentam mais a fusão de processos embrionários para a formação da face, e sim o nivelamento dos sulcos entre eles. Todos os dentes humanos têm uma dupla origem embrionária, pois se compõem de ectoderma e mesênquima/ectomesênquima, mas isso não facilita sua duplicação para formar dentes extranumerários.

ABSTRACT

Introduction: Mesiodens is a supernumerary tooth present in the anterior maxilla. Children with teeth alterations that could affect their facial features may experience harassment and teasing, leading to difficulties in social interaction. Objective: To report a clinical case of treatment in a pediatric patient with mesiodens. Additionally, we aimed to correlate the mesiodens to the quality of life and happiness through the Child Perceptions Questionnaire (CPQ8-10) and the Subjective Happiness Scale (SHS). Case report: A 7-year-old patient complaining about a tooth between the upper central incisors and esthetical problems his tooth caused, according to his grandmother. In the initial session, the CPQ8-10 and the SHS were applied. The treatment performed was mesiodent extraction and follow-up. Four months after extraction, teeth 11 and 21 spontaneously repositioned, without the need for orthodontic intervention. The initial results (22 points in CPQ8-10 and mean 2.5 in the ESF) showed a negative impact on quality of life. Six months after the initial session, the questionnaires were reapplied and an improvement in the results was observed (7 points in CPQ8-10 and mean 5.25 in SHS). Conclusion: The correct diagnosis and the best moment for treatment were keys for preventing occlusal problems in a patient with mesiodens. Additionally, mesiodens treatment significantly improved the child's quality of life and perceived happiness.


Introdução: Mesiodente é um dente supranumerário presente na maxila anterior. Crianças com alterações nos dentes que podem afetar suas características faciais podem sofrer bullying e dificuldades de interação social. Objetivo: Relatar um caso clínico de tratamento em um paciente com mesiodente. Adicionalmente, correlacionar o tratamento do mesiodente ao impacto na qualidade de vida e felicidade por meio do Child Perceptions Questionnaire (CPQ8-10) e da Escala Subjetiva de Felicidade (ESF). Relato do caso: Paciente de 7 anos tinha como queixa um dente entre os incisivos centrais superiores e diagnóstico de mesiodente. O paciente relatou sofrer bullying por conta disso. Na consulta inicial foram aplicados o CPQ8-10 e o ESF. O tratamento realizado foi exodontia do mesiodente e acompanhamento. Quatro meses após a exodontia houve aproximação espontânea dos dentes 11 e 21, sem a necessidade de intervenção ortodôntica. Os resultados iniciais (22 pontos no CPQ8-10 e média 2,5 no ESF) mostraram impacto negativo na qualidade de vida. Seis meses após a consulta inicial os questionários foram reaplicados e uma melhora nos resultados foi percebida (7 pontos no CPQ8-10 e média 5,25 no SHS). Conclusão: O diagnóstico correto e o melhor momento para o tratamento foram fundamentais para prevenir problemas oclusais. Além disso, o tratamento melhorou significativamente a qualidade de vida da criança e a felicidade percebida.

ABSTRACT

Abstract Mucopolysaccharidosis (MPS) is a group of rare and inherited metabolic disorders caused by the accumulation of macromolecule glycosaminoglycans inside lysosomes. Affected individuals may have dental and craniofacial tissue alterations, facilitating the development of several oral diseases. Objectives To assess, with panoramic radiographic images, the frequency of dental and maxillomandibular incidental findings among MPS individuals and compare them with non-MPS individuals. Methodology A cross-sectional study evaluating a sample of 14 MPS individuals and 28 non-MPS individuals aged from 5 to 26 years was carried out. They were matched for sex and age on a 2:1 proportion. Panoramic radiographs were assessed for the presence/absence of the following dental and maxillomandibular alterations: dental anomalies of number (hypodontia/dental agenesis, supernumerary teeth); anomalies of form (microdontia, macrodontia, conoid teeth, taurodontism, and root dilaceration); anomalies of position (impacted tooth, inverted tooth, tooth migration, partially bony teeth, complete bony teeth); periapical alterations (furcation lesion, circumscribed bone rarefaction); other alterations (radiolucent bone lesions, radiopaque bone lesions, radiopacity in the maxillary sinus, condylar hypoplasia). Differences between groups were tested by the Fisher's exact test and chi-square test (p<0.05). Results For intrarater agreement, Kappa values were 0.76 to 0.85. The presence of supernumerary teeth (p=0.003); conoid teeth (p=0.009); taurodontism (p<0.001); impacted teeth (p<0.001); partial bony teeth (p=0.040); complete bony teeth (p=0.013); and root dilaceration (p=0.047) were statistically more frequent in MPS individuals compared to non-MPS individuals. Bone rarefaction/furcation lesions (p=0.032), condylar hypoplasia (p<0.001), radiolucent bone lesions (p=0.001), and dentigerous cysts (p=0.002) were also more frequent in MPS individuals. Conclusion The presence of specific oral manifestations is more common in MPS individuals than non-MPS individuals.

ABSTRACT

Dimension, number and shape alterations are frequently observed dental anomalies. Objective: The aim of this study was to map the frequency, the preferred location and the most prevalent types of supernumerary teeth, in the studied population. In addition, to assess the interference that supernumerary teeth may cause in the ectopic eruption of the normal dental series teeth. Methods: This is an observational retrospective study. Data collection was performed by evaluation of dental records of patients treated in an orthodontic clinic. Patients' radiographs, photographs and gypsum dental models were analyzed and data recorded in protocol files, by previously trained undergraduate and postgraduate students. Records from 1984 to 2019 were evaluated, and evaluation lasted two months. Data were stored in Microsoft Office Excel (version 2016) for descriptive analysis. Results: From the 920 patients' records analyzed, 2.7% presented at least one supernumerary tooth, with preferred location on the anterior maxillary area and mandibular parapremolar area. The most prevalent type was the supplemental tooth, with normal eruption orientation and normal alveolar location. Conclusion: The supernumerary teeth of the studied population showed little interference in the ectopic eruption of the normal dental series. Most of the supernumerary teeth were impacted, and, approximately one third of the supernumerary teeth showed deviated eruptions.


Introdução: Alterações de dimensão, número e forma são anomalias dentárias comumente observadas. Objetivo: O objetivo foi mapear a frequência de dentes supranumerários na população estudada, sua localização preferida e os tipos mais prevalentes. Além disso, avaliar a interferência que os dentes supranumerários podem causar na erupção ectópica da série dental normal. Métodos: A pesquisa possui desenho retrospectivo observacional. A coleta de dados foi realizada pela avaliação de prontuários odontológicos dos pacientes atendidos em uma clínica ortodôntica. Foram analisados radiografias, fotografias e modelos de gesso dental dos pacientes e as informações foram registradas em arquivos de protocolo do estudo. A coleta de dados foi realizada por uma estudante de graduação e uma da pós-graduação, previamente calibradas. A coleta durou dois meses e foram avaliados registros de 1984 a 2019. Os dados foram tratados no programa Microsoft Office Excel (version 2016) com análise descritiva dos dados. Resultados: Dos 920 prontuários analisados, 2,7% apresentavam pelo menos um dente supranumerário, com localização preferida na área superior anterior e na área parapremolar mandibular. O tipo mais prevalente foi o dente suplementar, com orientação de erupção normal e localização alveolar normal. Conclusão: Os dentes supranumerários da população estudada neste estudo mostraram pouca interferência na erupção ectópica da série dental normal. A maioria dos dentes supranumerários estava em posição de impactação. E, aproximadamente um terço dos dentes supranumerários apresentaram desvios de erupção.

ABSTRACT

Abstract Objective: To determine the frequency and characteristics of mesiodens in Indian school children. Material and Methods: 1232 radiographs of patients attending the Department of Oral Medicine and Radiology of the age group of 4-15 years studied for the present retrospective study. The intraoral periapical radiographs and occlusal radiographs of the premaxilla were examined to determine the presence of mesiodens. The data regarding the presence of mesiodens, number, position, location on the arch, shape and associated complications were recorded. Results: Eleven patients had 14 mesiodens, with a frequency of 0.8%. The ratio of boys to girls was 1.2:1. Maximum mesiodens observed in the age group of 7-9 years. Most of the mesiodens were conical in shape and found on the palatal side. Fifty percent of the mesiodens were unerupted. The majority of patients (57.1%) had vertically positioned mesiodens. Midline diastema was the most common complication due to mesiodens (66.7%). Conclusion: Routine check-up during the primary dentition and mixed dentition stages helps for early detection of mesiodens and thus preventing complications. Early identification is useful for planning comprehensive management, initiating proper consultation and referral for evaluation and treatment.

ABSTRACT

Abstract Objective: To investigate the prevalence and characteristics of supernumerary teeth among patients attending the students' dental clinics at the Faculty of Dentistry of the Arab American University, Jenin, Palestine. Material and Methods: This is a descriptive, cross-sectional, retrospective study of 1970 digital panoramic radiographs of patients, age ranging between 12 and 50 years. The radiographs and dental records were reviewed for supernumerary teeth. For each patient with supernumerary teeth, were recorded the demographic variables, number, location, eruption status, type, and morphology, the developmental stages. Descriptive statistics were performed and results were tabulated. Results: Supernumerary teeth were detected in 17 subjects (0.86%), of which 13 were males and 4 were females with a male to female ratio of 3.25:1. Of the 17 patients, 64.7% had one supernumerary tooth while the others had two. The majority (78.3%) of the supernumeraries were located in the maxilla. Around 56.5% of the supernumeraries found in this study were located in the premaxilla. Half of the supernumeraries (52.2%) were erupted, and 47.8% were impacted. Mesiodens was the most frequently seen supernumerary teeth followed by distomolars and premolars. Most of the supernumeraries were fully developed, while 21.7% displayed only crown formation. Conclusion: The prevalence of supernumerary teeth in the study sample was found to be 0.86% and the most frequent type was mesiodens. Supplemental morphology was found to be the most common form of supernumerary teeth.

ABSTRACT

OBJECTIVE@#To explore the application of digital positioning guide plate in extraction of impacted supernumerary teeth and evaluate its clinical efficacy.@*METHODS@#From March to August, 2019, 30 patients with labial impacted supernumerary teeth treated in the Department of Oral and Maxillofacial Surgery, Stomatological Hospital, Southern Medical University were enrolled in this study. Fifteen of the patients were treated with digital positioning guide plate to remove the impacted supernumerary teeth (test group). According to the CBCT data and the dentition model of the patients, the positioning guide plate was positioned by avoiding the important anatomical structure with the tooth-bone surface as the support to design the soft tissue incision line and bone tissue exposure range. The other 15 patients who were treated without the use of the guide plate for operation served as the control group. The design time, tooth searching time, operation time and complications were compared between the two groups.@*RESULTS@#The positioning guide plate was well attached during the operation and allowed quick location of the supernumerary teeth while helping to expose the supernumerary teeth and avoid the damage of the adjacent important anatomical structures. The pre-operative design time was 50 ± 5 min in the test group and 0 min in the control group. The average time of tooth finding in the test group was 5±2 min, as compared with 10±3 min in the control group (=15.40, < 0.01); the average time of operation was significantly shorter in the test group than in the control group (25±4 min 45±6 min; =35.50, < 0.01). No intraoperative complications occurred in the test group, and slight deviation occurred in one case in the control group.@*CONCLUSIONS@#The application of digital positioning guide plate in extraction of embedded supernumerary teeth can significantly shorten the time of tooth finding, reduce the difficulty of operation, and improve the quality of operation.

ABSTRACT

RESUMEN: La displasia cleidocraneal (DCC), es un trastorno autosómico dominante poco común, que involucra principalmente a los huesos que se osifican por vía membranosa; afectando el cierre de fontanelas craneales y el desarrollo de las clavículas, además de anomalías dentales y vertebrales. El objetivo de este manuscrito fue reportar el caso de una paciente con DCC que presentó un queratoquiste odontogénico (QQO) intrasinusal. Presentamos el caso de una paciente de 81 años, diagnosticada en su niñez con DDC, que consultó por un desajuste protésico y molestias en relación a la zona del seno maxilar derecho. Clínicamente se observó desajuste de la prótesis y aumento de volumen de márgenes poco definidos en la zona maxilar derecha, color rosa coral; que se extendía por todo el margen hemimaxilar derecho hasta el fondo de vestíbulo; doloroso a la palpación, con un mes de evolución. Se solicitó CBCT, con el que se pudo verificar la presencia de un desarrollo tumoral de contenido similar a dentículos, ubicado en la totalidad del seno maxilar derecho; extendiéndose hasta el piso de la cavidad nasal y orbitaria. Se estableció la hipótesis diagnóstica de "odontoma compuesto". Se le intervino quirúrgicamente, bajo anestesia general, realizándose una excisión de la lesión; la que era de márgenes definidos, con cambios de coloración en tonos oscuros, con la inclusión de tres piezas dentarias; de aspecto maligno. Se logró enucleación completa, dejando remanente óseo limpio. La pieza fue enviada a estudio histopatológico. En informe histopatológico, describió la presencia de una lesion quistica con pared compatible con queratoquiste.


ABSTRACT: Cleidocranial dysplasia (CCD) is an uncommon autosomal dominant disorder that mainly involves bones that ossify via the membrane, affecting the closure of cranial fontanels and the development of the clavicles, as well as presenting dental and vertebral anomalies. The aim of this manuscritpt was to report a case of a patient with CCD who presented an intrasinusal odontogenic keratocyst.We present an 81-year-old female patient, diagnosed with this syndrome in childhood, who comes to our service for a prosthetic misalignment and discomfort of the right maxillary sinus area. Clinically, there was a mismatch of the prosthesis and an increase in the volume of undefined margins under it, coral pink color, which extended all over the right hemimaxillary margin to the bottom of the vestibule, painful on palpation, with a one month evolution. A CBCT was requested, which revealed the presence of a tumor development with content similar to denticles, located in the entire right maxillary sinus, extending to the floor of the nasal and orbital cavity. The diagnostic hypothesis of "compound odontoma" was established. The patient was operated on in the central ward, under general anesthesia performing the excisional biopsy of the lesion, which showed changes in coloration in dark tones, with defined edges, with the inclusion of three teeth showing malignancy aspects. Complete enucleation was achieved, leaving tumor-free clean bone remnant. In a histopathological report, the presence of a keratocyst wall was described, which is not very compatible given the appearance of the lesion, the presence of the dental pieces included in it, and the behavior of the lesion.

ABSTRACT

INTRODUCTION: The objective of this clinical case report is to describe the presence of bilateral fourth molars. The occurrence of supernumerary teeth (ST) is a relatively unusual dental anomaly. It is even more unusual to find patients with distomolar teeth also denominated fourth molar teeth. PRESENTATION OF THE CASE: This article describes a clinical case of a 24-year-old patient presenting with a maxillary fourth molar, who was diagnosed by dental x-ray, and surgical resolution of the case. CONCLUSION: Tooth extraction surgery was the clinical procedure chosen to treat the impacted tooth.


INTRODUÇÃO: O objetivo deste relato de caso clínico é descrever a presença de quarto molares bilaterais. A ocorrência de dentes supranumerários (ST) é uma anomalia dentária relativamente incomum. É ainda mais incomum encontrar pacientes com dentes distomolares também denominados dentes do quarto molar. APRESENTAÇÃO DO CASO: Este artigo descreve um caso clínico de um paciente de 24 anos que apresentava quarto molar superior, diagnosticado por radiografia dentária, e resolução cirúrgica do caso. CONCLUSÃO: A cirurgia de extração dentária foi o procedimento clínico escolhido para tratar o dente impactado.

ABSTRACT

Objective: To determine the occurrence of dental anomalies in patients with special needs from Barranquilla, Colombia. Material and Methods: An observational, cross-sectional descriptive study with a sample of 59 patients chosen at convenience for 6 months during the course of 2017. With prior approval by experts, an instrument that identified dental anomalies was applied, followed by an institutional clinical history, intraoral clinical examination and final evaluation of the study variables, with descriptive statistics. Results: With regards to age ranges, 25% of subjects were between 14 to 17 years, and 19% between 22 to 25 years. The average age was 14 (± 7.9). No cases were found in the age range of 26 to 29 years. In terms of gender, males predominated with 78%. The anomaly that predominated was fluorosis (50.8%), followed by agenesis (23.7%). The syndrome and / or disorder with the highest frequency of dental anomalies was mental retardation with 39%, followed by behavioral disorders (22%) Conclusion: The frequency of dental anomalies in patients with special needs was evidenced, showing higher prevalence of dental fluorosis in patients with mental retardation, and a higher incidence in males; in the patients with syndromes and / or disorders who were observed, there were a few oral findings unrelated to dental anomalies.

ABSTRACT

Objective: To identify the dental anomalies that can modify the occlusal characteristics and their distribution in these occlusal alterations in the skeletal patterns of children. Material and Methods: We analyzed charts, panoramic and periapical radiographs of children aged 5 to 12 years from 2009 to 2012. The facial pattern was evaluated through subjective face analysis and cephalometric data, as well as the occlusion of patients with and without (control) dental anomalies. The relationship between the presence of dental anomalies and malocclusion was analyzed by the Chi-square test with significance level of 5%. Results: 73 children (27.8%) presented dental anomalies, being 49.3% in girls and 50.7% in boys in a total of 88 teeth involved. Anomalies observed in decreasing order were: enamel hypoplasias, eruptive ectopias, agenesis, supernumerary teeth, corono-radicular dilaceration, microdontia, transposition and imperfect amelogenesis. Of these, 22.2% presented associated dental anomalies, whose ectopic eruption with enamel hypoplasia were the most frequently encountered. When comparing the control group with children with dental abnormalities it was observed a significant relationship between the presence of dental anomalies and malocclusion (p<0.05). The most frequent alteration among patients with dental anomalies was deep overbite (24.6%), followed by crowding (23.3%), posterior crossbite (14.2%), anterior open bite (12.9%) and anterior crossbite (0.3%). Conclusion: Dental dysgenesis interferes with the development of occlusion and the resulting occlusal problems are distributed differently, taking into account the skeletal facial pattern in patients with and without dental anomalies.

ABSTRACT

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)

ABSTRACT

Abstract Objective: To determine the frequency distribution of dental anomalies in people with Down syndrome. Material and Methods: This cross-sectional study was developed in Jakarta, Indonesia, and evaluated 174 individuals with Down syndrome aged 14-53 years. Were collected information regarding the tooth number, tooth size, shape, and structure. Descriptive statistics were used to calculate the absolute and relative frequencies. The Pearson chi-square test was used in bivariate analysis. The significance threshold was set at 5% Results: There were 70 female subjects (40.2%) and 104 male subjects (59.8%) with an average age of 19.2 years. In terms of anomalies of tooth number, hypodontia (80.9%), supernumerary teeth (12.4%), and combined hypodontia and supernumerary teeth (12.4%) were identified. In terms of anomalies of tooth size, microdontia (98.8%) is the most common anomaly. Anomalies of tooth shape included fusion (66.67%) and talon's cusp (33.3%), whereas anomalies of tooth structure included enamel hypoplasia (70.8%), enamel hypocalcification (4.2%), combined enamel hypoplasia and hypocalcification (12.5%), and tooth discoloration (12.5%) Conclusion: Individuals with Down syndrome in Jakarta showed a high prevalence of dental anomalies, with hypodontia and microdontia being the most common anomalies showing a tendency to occur predominantly in males.

ABSTRACT

PURPOSE: The prevalence of supernumerary teeth has been reported to be between 0.1% and 3.8%. The aim of this study was to determine the prevalence, clinical significance, and associated pathologies of fourth molars based on a retrospective study and a literature review. MATERIALS AND METHODS: A 5-year retrospective prevalence study was conducted at the Department of Oral Diagnosis and Dentomaxillofacial Radiology of Okayama University Hospital, Okayama, Japan. The study involved extracting data from the digital records of patients from January 1, 2013 through December 31, 2017. The sampling frame included all patients who had panoramic radiographs, cone-beam computed tomography (CT), and multislice CT images during the period under review. RESULTS: A total of 26,721 cases were reviewed and 87 fourth molars were identified. The prevalence of fourth molars in the 5-year study at Okayama was calculated as 0.32%. The mean age of patients with a fourth molar was 30.43 years, and the male-to-female ratio was 1:0.98. The vast majority of cases were in the maxilla (92%) and had normal shapes (89.7%); furthermore, 82.8% of cases were unerupted. CONCLUSION: The prevalence of fourth molars in the study population was found to be 0.32%, and fourth molars occurred with approximately equal frequency in males and females. Fourth molars were more common in the maxilla and were predominantly unerupted and small.

ABSTRACT

OBJECTIVE@#To study the application of surgical locating guides based on cone beam computed tomography (CBCT) and computer-aided design/computer-aided manufacturing (CAD/CAM) technique on extraction of impacted supernumerary teeth.@*METHODS@#This study included 15 patients with impacted supernumerary teeth in anterior maxillary. Surgical approach was determined by CBCT. Surgical locating guides of labial approach or palatal approach were designed and fabricated by CAD/CAM technique. Impacted supernumerary teeth were extracted under the location of surgical locating guides.@*RESULTS@#Surgical locating guides were well attached in the operation. The impacted supernumerary teeth were located and exposed rapidly, and the adjacent important anatomical structures were avoided.@*CONCLUSIONS@#Surgical locating guides benefit the accurate detection and reduction of trauma in extraction of impacted supernumerary teeth.
