ABSTRACT

En raras ocasiones, el canino mandibular derecho o izquierdo se coloca en el lado opuesto al habitual. Esta perturbación se define como la transmigración. Existen diversas teorías de su etiología, así como factores que la condicionan. La transmigración mandibular es un término que no está descrito en la literatura contemporánea y son pocos los casos reportados a nivel mundial. Presentamos un caso de trasmigración de canino mandibular derecho, posicionado por debajo del agujero mentoniano de lado izquierdo, cerca del borde basal mandibular, el cual se extrajo bajo anestesia general. Presentamos la etiología, técnica quirúrgica y consideraciones especiales en casos de trasmigración de canino mandibular (AU)


In rare occasions right or left mandibular canine is positionated at opposed side of habitual. This disturbance is defined as transmigration. There exist diverse theories about its etiology as well as conditioning factors. Mandibular transmigration is a non described term in modern literature and there are only a few reported cases at world level. We present one case of right canine transmigration positionated intimately below of left side mentonian hole near of mandibular basal edge which it was extracted under general anesthesia. We present also the etiology, surgical technique and special considerations of mandibular canine transmigration cases (AU)

ABSTRACT

Introducción:Los caninos permanentes son dientes importantes para el aparato estomatognático. La retención de estos por limitación física en su erupción debe ser tratada en forma temprana con aparatología ortodóncica que permita una rehabilitación precoz y evitar tratamientos quirúrgicos más cruentos. Objetivo: Caracterizar los pacientes pediátricos con caninos permanentes retenidos atendidos en el Servicio de Cirugía Máxilofacial del Hospital Pediátrico Universitario Centro Habana, en el período de 2012 a 2015. Material y Métodos:Se realizó un estudio retrospectivo descriptivo en pacientes pediátricos con caninos permanentes retenidos atendidos en el Servicio de Cirugía Maxilofacial del Hospital Pediátrico Universitario Centro Habana, durante el período mencionado. Resultados: Se obtuvo un predominio del sexo femenino (69 por ciento).La edad de mayor detección de esta anomalía dentaria fue la de 13 años (26 por ciento). El canino permanente que más se retuvo fue el superior derecho (62 por ciento). El tipo de retención más frecuente la constituyó la unilateral (67 por ciento). La retención Clase I maxilar fue la de mayor presentación clínica (25 por ciento). El tratamiento más empleado fue la excéresis quirúrgica (50 por ciento). Conclusiones: En los pacientes pediátricos estudiados, los caninos retenidos se presentan fundamentalmente en el sexo femenino y los 13 años es la edad de mayor detección de esta anomalía dentaria. El canino permanente que más se retiene es el superior derecho (13) por palatino y la excéresis quirúrgica es el tratamiento más empleado(AU)

ABSTRACT

ABSTRACT The early recognition of risk factors for the occurrence of palatally displaced canines (PDC) can increase the possibility of impaction prevention. Objective To estimate the risk of PDC occurrence in children with dental anomalies identified early during mixed dentition. Material and Methods The sample comprised 730 longitudinal orthodontic records from children (448 females and 282 males) with an initial mean age of 8.3 years (SD=1.36). The dental anomaly group (DA) included 263 records of patients with at least one dental anomaly identified in the initial or middle mixed dentition. The non-dental anomaly group (NDA) was composed of 467 records of patients with no dental anomalies. The occurrence of PDC in both groups was diagnosed using panoramic and periapical radiographs taken in the late mixed dentition or early permanent dentition. The prevalence of PDC in patients with and without early diagnosed dental anomalies was compared using the chi-square test (p<0.01), relative risk assessments (RR), and positive and negative predictive values (PPV and NPV). Results PDC frequency was 16.35% and 6.2% in DA and NDA groups, respectively. A statistically significant difference was observed between groups (p<0.01), with greater risk of PDC development in the DA group (RR=2.63). The PPV and NPV was 16% and 93%, respectively. Small maxillary lateral incisors, deciduous molar infraocclusion, and mandibular second premolar distoangulation were associated with PDC. Conclusion Children with dental anomalies diagnosed during early mixed dentition have an approximately two and a half fold increased risk of developing PDC during late mixed dentition compared with children without dental anomalies.

ABSTRACT

Loss of anterior teeth in patients with diastema presents a great esthetic challenge for the prosthodontists. In cases with midline diastema and interdental spacing, the option of a conventional fixed partial denture becomes impossible to use. This is because of the excess space available for pontic, which makes the incorporation of the diastema in the planned prosthesis, a compulsion. Diastema closure in such cases with the help of conventional fixed partial denture is bound to result in esthetic failures. This article presents a case of midline diastema successfully maintained by lingual loop connectors between the pontic and the retainers to achieve esthetic rehabilitation in the mandibular anterior region.

ABSTRACT

El propósito de esta presentación es motivar a los odontólogos generales a realizar un seguimiento temprano, clínico y radiológico, de sus pacientes en crecimiento, para valorar el desarrollo de la oclusión y poder diagnosticar precozmente la posibilidad de retenciones dentarias y derivar a especialistas, con la finalidad de guiar la secuencia eruptiva. Se presenta el caso clínico de una paciente que efectuó consultas a varios odontólogos durante muchos años, quienes le solicitaron estudios radiológicos y como único tratamiento, le colocaron una placa removible, reponiendo los dientes que no habían erupcionado. El diagnóstico y tratamiento interdisciplinario permitió rehabiliar la función gnatológica con sus propios dientes, recuperar la estética dental y la sonrisa de la paciente

ABSTRACT

When the tooth, instead of erupting in its normal position, remains impacted and crosses midline and is seen on the opposite side of the jaw, it is termed as Transmigration; e.g., right side tooth is seen on the left side and vice-versa. This phenomenon occurs without any pathology intervening cause. Canines are commonly seen unerupted and remain impacted, but rarely seen crossing the midline and migrating to the opposite side. They are usually symptomless. Here, we present two such rare cases of transmigration of the mandibular canine, one from the right side to the left side and appearing piercing the lower border of the mandible and producing a hard bulge on the left side of the lower jaw, but without any pain. The other case is of transmigration of mandibular left canine toward the right side well below the inferior alveolar canal beyond mental foramen facing toward posterior region of the mandible and causing pain symptoms in the jaw due to its close proximity to inferior alveolar canal. It is very essential to have panoramic radiograph to detect such abnormalities at an early stage to plan treatment and avoid future complications. Cone beam computed tomography images also play an important role.

ABSTRACT

As oclusopatias constituem um focos de discussões na Saúde Pública, por este motivo é necessário incorporar procedimentos para sua correção que sejam de baixo custo, fácil execução e que possam ser realizados nos serviços de saúde. As Pistas Diretas Planas reúne essas características que as tornam vantajosas para a correção de mordida cruzada. O tratamento foi realizado na Faculdade de Odontologia de Araçatuba- UNESP, no iniciando-se no ano 2006. Objetivo do trabalho foi apresentar um caso clínico em que foi realizado a correção da mordida cruzada unilateral com recursos disponíveis em um consultório público. A paciente IMD, do sexo feminino, com 6 anos, apresentando mordida cruzada unilateral funcional dos dentes caninos e também dos dentes posteriores. Detectou-se, ainda uma diminuição transversal do arco superior o que conduziu a uma condição de mordida cruzada unilateral posterior. Foram realizados os ajustes oclusais nos caninos e dentes posteriores, porém não foi suficiente para reestabelecer o equilíbrio oclusal. Decidiu-se confeccionar as pistas diretas nos dentes caninos permitindo um equilíbrio funcional, o que evitou a alteração dos movimentos mastigatórios durante a fase de crescimento e correção da má-oclusão. A paciente realizou retornos semestrais para avaliação das condições das pistas e necessidades de novos ajustes oclusais. O acompanhamento foi realizado por cinco anos, até a estabilização da dentição permanente assegurando o sucesso do tratamento. Conclui-se que as Pistas Diretas Planas foram eficazes para correção da mordida cruzada posterior unilateral, e é essencial salientar o fato de que esse procedimento pode ser realizado nos serviços públicos(AU)

Fueron realizados controles semestrales para la evaluación de la evolución del paciente y la necesidad o no de nuevos ajustes oclusales. El seguimiento fue realizado por 5 años, hasta la estabilización de la dentición permanente asegurando tratamiento. Se concluye que las Pistas Directas Planas fueron eficaces para la corrección de la mordida cruzada posterior unilateral, es esencial resaltar que ese procedimiento puede ser realizado en los servicios públicos(AU)


The malocclusions are one focus of discussions in public health, due to which it is necessary to incorporate correction procedures that are inexpensive, easy to perform and which can be made in health services. Planas Direct Tracks meet such characteristics which make them advantageous for the crossbite correction. The aim of this study was to present a case in which correction of unilateral crossbite was performed with the resources available in a public clinic. This is a 6 year-old patient who presented functional unilateral crossbite in canines and posterior teeth. A cross decreased maxillary arch leading to a condition of unilateral posterior crossbite was detected. Occlusal adjustments were performed in canine and posterior teeth; however it was not enough to restore the occlusal balance. It was decided to prepare Planas Direct Tracks in canines, allowing functional balance, which prevented masticatory movement alteration during the growth phase and malocclusion correction. Controls were performed every six months to evaluate the patient's progress and whether or not new occlusal adjustments were necessary. Monitoring and treatment were conducted for 5 years, until stabilization of the permanent dentition ensuring treatment. It is concluded that Planas Direct Tracks were effective for the correction of unilateral posterior crossbite. So, it is essential to note that this procedure can be performed in public services(AU)

ABSTRACT

The normal anatomy of canines teeth comprises one root and one large canal centered through its axis; however some canines may present two roots and two canals. Thus, the knowledge of normal root canal anatomy and their variations is essential to minimize the possibility of occurrence of accidents during the development of dental treatments. In this report we describe a case of bilateral mandibular canines with two roots and two canals found radiographically in the same individual.


La anatomía normal de los dientes caninos comprende una raíz y un gran canal centrado a través de su eje, sin embargo algunos dientes canino pueden presentar dos raíces y dos canales. Así, el conocimiento de la anatomía normal de canal de la raíz y sus variaciones son esenciales para minimizar la posibilidad de accidentes durante el desarrollo de tratamientos dentales. En este informe se describe el caso de dientes caninos mandibulares con dos raíces y dos canales bilateralmente hallados radiográficamente en el mismo individuo.

ABSTRACT

Os tratamentos de pacientes que apresentam caninos retidos ou inclusos podem gerar grande apreensão, já que o prognóstico nem sempre é favorável, envolvendo riscos de ocorrer anquiloses, descoloração, desvitalização, reabsorção radicular dos dentes envolvidos e dentes adjacentes, recessão gengival e deficiência de gengiva inserida. Será apresentado nesse artigo um caso clínico de colagem de acessório para o tracionamento e uso de barra transpalatina associada a alça de TMA (titanium-molibdenum alloy) evitando, assim, o excessivo apoio dentossuportado. Esse dispositivo se mostrou eficiente e confiável.

ABSTRACT

Oligodontia is a rare congenital disorder consisting in the absence of six or more teeth. This case report describes a multidisciplinary treatment approach for a 12-year-old male with absence of 11 permanent teeth. Prior to any procedure, all primary teeth were scheduled for extraction due to poor crown-to-root ratio. The treatment plan comprised two phases: 1. orthodontic and speech therapy aimed at overbite and anterior open bite adjustment, as well as tongue position improvement; and 2. prosthetic treatment by insertion of removable temporary partial dentures. The multidisciplinary treatment involving orthodontics, speech and prosthetic therapies have reestablished the masticatory function and aesthetics, allowing the patient to achieve greater self-esteem and better social acceptance.


Resumo A oligodontia é uma doença rara, congênita, caracterizada pela ausência de seis ou mais dentes. Este relato de caso descreve uma abordagem terapêutica multidisciplinar de um adolescente de 12 anos de idade com ausência de 11 dentes permanentes. Antes de qualquer procedimento, todos os dentes decíduos foram extraídos devido à pobre relação coroa-raiz. O plano de tratamento foi constituído por duas fases: 1. terapia ortodôntica e fonoaudiológica com o objetivo de ajuste de sobre-mordida e mordida aberta anterior, bem como melhoria da posição da língua, e 2. tratamento reabilitador protético através da instalação de próteses parciais removíveis provisórias. A abordagem multidisciplinar envolvendo os tratamentos ortodônticos, fonoaudiológico e protético reestabeleceram a função mastigatória e a estética, melhorando a autoestima e aceitação social do paciente. .

ABSTRACT

Introduction: The talon cusp is defined as a developmental anomaly in which an accessory cusp-like structure projects in the area of the cingulum or cementoenamel junction in the anterior teeth attached to the lingual surface of the crown, ranging in size, shape, length and degree of union with the surface. Case report: This study aimed to report a case of a patient who came to Clinic for Preventive Dentistry of Federal University of Pernambuco, Recife-PE, Brazil, complaining of pain in the upper left region. The clinical exam observed the presence of a supernumerary tooth with talon cusp type III in the canine region which had a carious lesion in the developmental groove at the mesial surface and caused a prolonged retention of permanent tooth. Conclusion: With this we want to emphasize that the Dental Surgeon be aware of the changes caused by dental morphological variations, seeking to conduct a proper treatment plan, meeting the functional and aesthetic needs of the patient.

ABSTRACT

Introdução: Os dentes são estruturas duras e salientes que são compostas por polpa, dentina e esmalte e que estão implantadas nos ossos maxilares de muitos vertebrados. Anatomicamente, os dentes são divididos em duas partes, uma coroa e uma ou mais raízes. Os dentes podem apresentar raízes acessórias ou upranumerárias. O desenvolvimento de uma raiz supranumerária pode estar relacionado a trauma, pressão ou doença metabólica que afeta a bainha epitelial de Hertwig. Raízes supranumerárias podem ser totalmente desenvolvidas em tamanho e forma ou pequenas e rudimentares. Objetivo: Determinar a prevalência de raízes supranumerárias em caninos inferiores numa população de jovens em relação ao sexo e a localização. Materiais e métodos: Quinhentas e trinta radiografias periapicais de estudantes da Universidade Federal do Paraná (UFPR) foram avaliadas em ambiente escuro, usando um negatoscópio e uma máscara para evitar claridade excessiva. Cada radiografia foi analisada por dois observadores previamente treinados. Os dados foram tabulados e submetidos à análise estatística. Resultados: Os resultados revelaram que a prevalência de raízes supranumerárias nos caninos inferiores foi de 15 casos (2,83%). Em relação ao sexo, a prevalência desta anomalia foi de doze casos em mulheres (80%) e três em homens (20%). Quanto à localização, seis casos foram bilaterais (40%), sendo todos em indivíduos do sexo feminino e nove casos unilaterais (60%) – seis em mulheres e três em homens. Conclusão: A ocorrência de raízes supranumerárias em caninos inferiores é baixa e acomete mais as mulheres.


Introduction: Teeth are hard and protruding structures that are composed of pulp, dentin and enamel and are implanted in the jaws of many vertebrates. Anatomically, the teeth are divided into two parts, a crown and one or more roots. The teeth may exhibit additional or supernumerary roots. The development of a supernumerary root may be related to trauma, pressure or metabolic disease that affects the epithelial sheath of Hertwig. Supernumerary roots can be fully developed in size and shape and small or rudimentary. Objective: To determine the prevalence of supernumerary roots in mandibular canine in a young adult population with regard to sex and location. Materials and methods: Five hundred and thirty periapical radiographs from students of Universidade Federal do Paraná (UFPR) were evaluated in darkened room, using a light box and a mask to avoid excessive brightness. Results: The results showed that the prevalence of the supernumerary lower canines roots were 15 cases (2.83%). In relation to sex, the prevalence of this anomaly showed twelve cases in women (80%) and three men (20%). Six (40%) cases had their bilateral presentation and all occurred in females. Nine individuals presented unilateral occurrence (60%) – six women and three men. Conclusion: The occurrence of supernumerary roots in mandibular canine is low and affects more females.

ABSTRACT

Maxillary canine impaction is a common occurrence, especially in the palate, despite sufficient space in the arch for tooth alignment. A proper approach requires knowledge of different specialties of dentistry, such as orthodontics, surgery, radiology, and periodontology, which are generally not centered on a single professional. The causes for canine impaction may be either generalized or localized, and the diagnosis should be made through specific clinical and radiographic examination. The prognosis of surgical–orthodontic treatment depends on the position of the canine in relation to the neighboring teeth and height of the alveolar process, in addition to careful surgical technique, considering that there are risks involved, such as ankylosis, loss of tooth vitality, root resorption of the involved tooth and adjacent teeth, and damage to supporting tissues. Given the important role played by impacted maxillary canines, their traction is the treatment of choice in orthodontically treated patients. The present study reviews the literature on important factors to be considered when approaching impacted canines, such as therapeutic possibilities, their advantages and disadvantages.


A impactação de caninos superiores é uma ocorrência freqüente, especialmente na região palatina, ainda que na presença de espaço suficiente para seu alinhamento na arcada. A abordagem exige conhecimentos de diferentes especialidades da odontologia, tais como a ortodontia, cirurgia, radiologia e periodontia e que, em geral, não se centram em um único profissional. Pode ser causada por fatores de ordem geral ou local, sendo que seu diagnóstico deve ser realizado por meio de exames clínico e radiográfico específicos. O prognóstico do tratamento ortodôntico–cirúrgico ira depender da posição do canino em relação aos dentes vizinhos e da sua altura no processo alveolar, além de técnica cirúrgica cuidadosa, haja vista que envolve riscos, como: anquilose, desvitalização, reabsorção radicular do dente envolvido e dos dentes adjacentes e dano aos tecidos de suporte. Em virtude das importantes funções desempenhadas pelos caninos inclusos superiores, o seu aproveitamento através do tracionamento é o tratamento de eleição nos pacientes assistidos ortodonticamente. O presente trabalho traz uma revisão bibliográfica acerca de importantes fatores a serem considerados na abordagem dos caninos impactados, tais como as possibilidades terapêuticas, suas vantagens e desvantagens.

ABSTRACT

A má oclusão de Classe II divisão 1 ou 2, subdivisão direita, é caracterizada pela relação de Classe II somente nos molares do lado direito. Nesse tipo de má oclusão, normalmente, ocorre mal posicionamento dos dentes no arco alveolar, como por exemplo apinhamentos dentários no mesmo lado da Classe II (subdivisão). O presente artigo ilustra o tratamento de uma má oclusão de Classe II, subdivisão direita, com o emprego do quadri-hélice, arcos seccionados e arco utilidade, segundo a terapia bioprogressiva de Ricketts.

ABSTRACT

Although developmental anomalies of tooth number are quite common in permanent dentition, concomitant occurrence of hypohyperdontia is a very rare mixed numeric anomalous condition of teeth. Very few cases of this condition have been reported in the English literature. Here we report such a rare case noted in a 26 year-old male dental graduate with no other associated systemic condition or syndrome.

ABSTRACT

PURPOSE: Morphological dental anomalies of the maxillary lateral incisors are relatively common. However, their simultaneous occurrence is a relatively rare event. We report a case of dens invaginatus and talon cusp concurrently affecting maxillary lateral incisors. The etiology, pathophysiology, association with other dental anomalies, as well as various treatment modalities of these anomalies are discussed. CASE DESCRIPTION: An 18-year-old male patient reported with a complaint of crowding of maxillary front teeth. On intraoral examination, permanent dentition with Class I malocclusion with anterior crowding was observed. Tooth 12 showed a radiopaque invagination from a lingual pit but confined to the crown of the tooth. This invagination was approximately circular with a central core of radiolucency, which was consistent with the diagnosis of a dens invaginatus type I. Tooth 22 showed the talon cusp as a typical inverted cone with enamel and dentine layers and a pulp horn extending only into the base of the cusp. Talon cusp was treated by prophylactic enameloplasty to avoid plaque accumulation, the deep lingual pit was sealed using composite resin and regular clinical and radiographic follow-up was advised. Patient was scheduled for orthodontic treatment to correct crowding of maxillary anterior teeth. CONCLUSION: We emphasize the fact that detailed clinical and radiographic examination of the maxillary lateral incisors is vital in avoiding complications.


OBJETIVO: Anomalias morfológicas dentárias dos incisivos laterais superiores são relativamente comuns. No entanto, a sua ocorrência simultânea é um evento relativamente raro. Relatamos um caso de dens invaginatus e cúspide talon simultaneamente afetando incisivos laterais superiores. A etiologia, fisiopatologia, associação com outras anomalias dentárias, bem como várias modalidades de tratamento destas anomalias são discutidas. DESCRIÇÃO DO CASO: Um paciente de 18 anos, sexo masculino, relatou com queixa de apinhamento dos dentes anteriores superiores. Ao exame intraoral observou-se dentição permanente com má oclusão Classe I com apinhamento anterior. O dente 12 mostrou uma invaginação radiopaca lingual, confinada à coroa do dente. Esta invaginação era aproximadamente circular, com um núcleo central de radioluscência, que foi compatível com o diagnóstico de dens invaginatus tipo I. O dente 22 apresentou uma cúspide talon como um cone invertido típico com esmalte e dentina em camadas. A cúspide talon foi tratada por ameloplastia profilática para evitar acúmulo de placa, a fissura lingual foi selada com resina composta e foram aconselhados controles clínicos e radiográficos. O paciente foi encaminhado para tratamento ortodôntico para corrigir o apinhamento dos dentes anteriores superiores. CONCLUSÃO: Enfatizamos o fato de que o exame clínico e radiográfico detalhado dos incisivos laterais superiores é vital para evitar complicações.

ABSTRACT

Objective: To present and discuss a rare case of transmigration of bilateral mandibular canines. To review the literature and to discuss treatment. Discussion: Transmigration of the canine tooth is an uncommonphenomenon, often undetected in routine dental examinations. The less common finding is type 5 (the canine is positioned vertically in the midline with the long axis of the tooth crossing the midline)and the least common phenomenon is bilateral occurrence of type 5.
