Dental trauma clinically mimicking single central incisor syndrome =Traumatismo dentário mimetizando clinicamente a síndrome do incisivo central único  [cached]
Moreira, Rafaela Nogueira et al.
Revista Odonto Ciência , 2012,
Abstract: Objetivo: Apresentar um caso clínico de ausência de um incisivo central perdido por traumatismo e encaminhado ao ortodontista com suspeita de apresentar síndrome do incisivo central único (SMMCI). Descri o do caso: Paciente gênero feminino, 12 anos com queixa da aparência de seus dentes. Ao exame intrabucal observou-se a presen a de um incisivo central único localizado na linha média sem espa amentos em rela o aos incisivos laterais superiores. A paciente relatou dois episódios de avuls o dos dentes 11 e 21, cerca de quatro anos antes. No entanto, devido a sintomas de dor após reimplante, o dente 11 foi extraído. A radiografia panoramica e análise cefalométrica revelou a presen a de tratamento insatisfatório do canal radicular do dente 21, um perfil reto e padr o de equilíbrio facial. Extra o do dente 21 foi realizada, com tra o posterior dos dentes superiores na dire o mesial, seguido pela transforma o estética dos incisivos laterais em incisivos centrais e dos caninos em incisivos laterais. Conclus o: O traumatismo seguido de perda dentária pode mimetizar um quadro de síndrome do incisivo central único. Purpose: This paper presents a clinical case in which a patient was missing a median central incisor due to trauma but was referred for orthodontic treatment because of suspicions of solitary median maxillary central incisor (SMMCI) syndrome. Case description: A 12-year-old female patient visited the clinic with concerns about the appearance of her teeth. An oral examination revealed the presence of a single central incisor that was located on the midline and was adjacent to the maxillary lateral incisors. The patient reported two episodes of dental avulsion (of teeth 11 and 21) that had occurred approximately four years earlier. Tooth 11 was replanted; however, it was subsequently extracted due to pain. A panoramic radiograph and cephalometric analysis revealed a history of unsuccessful root canal treatment on tooth 21, a straight profile and symmetrical facial features. Tooth 21 was extracted, followed by the traction of the maxillary teeth in the mesial direction and the esthetic transformation of the lateral incisors into central incisors and the canines into lateral incisors. Conclusion: Dental trauma followed by tooth loss may mimic solitary median maxillary central incisor syndrome.

Abstract: Objetivo: Descrever o acompanhamento de seis anos de um paciente que sofreu trauma na denti o decídua e, como conseqüência, apresentou malforma o radicular do sucessor permanente. Descri o do caso: Um menino de 5 anos traumatizou o incisivo central superior durante queda de bicicleta. Como consequência da avuls o do incisivo esquerdo, houve a dilacera o radicular do sucessor permanente. Foi realizado o acompanhamento periódico clínico e radiográfico. O dente completou sua erup o um ano após a seqüela foi detectada e apresenta-se funcional no arco, apesar da malforma o. Conclus o: Esta caso refor a a necessidade do acompanhamento a longo prazo e de intervir-se apenas quando realmente necessário, visando evitar danos ao dente permanente. Purpose: To describe the management and six-year follow-up of a patient who suffered trauma in primary dentition and, as a consequence, presented root malformation in permanent tooth. Case description: A 5-years-old boy sustained trauma in primary maxillary anterior teeth due to a bicycle fall. As consequence of avulsion of left central incisor, the boy presented root dilaceration of the permanent successor. Radiography and clinical monitoring of the case were regularly performed. The tooth completed its eruption one year after sequel was detected and is currently successfully functional in the arch, despite the malformation. Conclusion: This case reinforces the need of long term follow-up in order to avoid any risks of further tooth damage, intervening only when necessary.

Journal of the Indian Society of Pedodontics and Preventive Dentistry , 2006,
Abstract: Most of the supernumerary teeth are located in anterior maxillary region with their presence giving rise to a variety of clinical problems. Occurrence of supernumerary supplemental mandibular central incisor is a rare phenomenon. This case report describes a rare case of supernumerary supplemental mandibular central incisor which had erupted labially causig mild crowding in the anterior midline region.
Impacted Maxillary Central Incisor With Dilaceration  [PDF]
Vinay Kumar Reddy K,Venkateswara Rao G,Jaya Kiran M
Indian Journal of Dental Advancements , 2011,
Abstract: Maxillary central incisor impactions occur infrequently. Their origins include various local causes, such as odontoma, supernumerary teeth, and space loss. Dilaceration is one of the causes of permanent maxillary incisor eruption failure. It is a developmental distortion of the form of a tooth that commonly occurs in permanent incisors as result of trauma to the primary predecessors whose apices lie close to the permanent tooth germ. A case of impacted maxillary left central incisor with dilaceration in a young patient is presented.
Solitary median maxillary central incisor (SMMCI) syndrome
Roger K Hall
Orphanet Journal of Rare Diseases , 2006, DOI: 10.1186/1750-1172-1-12
Abstract: The name originally given to this syndrome by Hall et al. [1], "Solitary median maxillary central incisor, short stature, choanal atresia/midnasal stenosis syndrome", is now customarily shortened to the first part of this name: "Solitary median maxillary central incisor syndrome" or SMMCI syndrome, as the other features are not necessarily present in all cases. The use of the full description of the single incisor tooth in the name is important, as it emphasises the unique form and position of this tooth, which is the characteristic and most readily observed feature or trait of the condition.The early observations of this condition [2-8] merely referred to the congenital and hereditary absence of one central incisor. When the association with short stature was recognised in 1976, the name Monosuperoincisivodontic dwarfism was given by Rappaport et al. [9], but it was soon recognised that short stature was not always present in the disorder [10]. The names "single central incisor syndrome" or "single maxillary central incisor" or "single incisor" suggested by other authors [11-15], do not adequately describe the peculiarly formed incisor tooth.To accurately describe the characteristic tooth present in this syndrome, it is necessary to specify:? Solitary: the tooth present exists as the only central incisor tooth in the maxilla.? Median: this tooth is present precisely in the midline of the maxillary alveolus (a single central incisor tooth present to one or other side of the midline indicates that the contralateral tooth has been lost from trauma or disease, or did not continue to develop beyond the cellular stage, the tooth germ being resorbed).? Maxillary: this characteristic tooth occurs only in the maxilla and not in the mandible.? Central Incisor: the tooth is a central incisor tooth, although of unusual crown form and is not a supernumerary tooth (mesiodens).Hence, the acronym SMMCI syndrome.The following circumstances where only one central incisor tooth is pr

Abstract: Dilacerated teeth are commonly seen in the maxillary anterior region. They are a cause for concern to both patients as well as parents when such teeth do not erupt or erupt in an unusual position. Careful planning is required while aligning such teeth. Orthodontists often hesitate aligning severely dilacerated teeth due to high chances of failure. A case of a dilacerated and malposed right central incisor in an eleven-year-old male patient is presented here. The tooth was orthodontically repositioned despite its unusual position and severely dilacerated root. Key words : Dilacerated teeth; Malposed teeth; Dilacerated central incisor.

RSBO , 2011,
Abstract: Introduction and objective: The success of endodontic treatment requires the knowledge of tooth morphology and its variations. Case report: This clinical article reports an unusual root canal configuration that was detected in a maxillary central incisor with two root canals, demonstrated by radiographic and computerized tomography exams. Conclusion: Knowledge of endodontic anatomy as well as the obtainment of both preoperative radiographs and tomography is important to detect abnormal tooth morphology.
Internal root resorption in the maxillary central incisor
Josué MARTOS,Luiz Fernando Machado SILVEIRA,Jaqueline de Moraes SOUZA,Mozara Mignoni VIEIRA
RSBO , 2010,
Abstract: Introduction: Internal root resorption is a chronic inflammatory process initiated within the pulp space with the loss of dentin. The clastic cells present in the pulp tissue trigger a progressive resorption phenomenon. Case report and conclusion: This paper reports a clinical case of an internal root resorption in the permanent central incisor, at the middle third of the root canal. Because it is asymptomatic,internal root resorption needs an early diagnosis in order to institute the endodontic treatment before the process compromises the mineralized structures of the tooth.

Journal of the Indian Society of Pedodontics and Preventive Dentistry , 2006,
Abstract: Although impaction of a permanent tooth is rarely diagnosed during the mixed dentition period, an impacted central incisor is usually diagnosed accurately when there is delay in the eruption of tooth. In this article, the impacted incisor was moved into it′s proper position with surgical exposure and orthodontic traction, after which it showed good stability.
Impaction of the Maxillary Central Incisor Associated with Supernumerary Tooth: Surgical and Orthodontic Treatment

People's Journal of Scientific Research , 2011,
Abstract: Impaction of maxillary permanent incisor is not a frequently case in dental practice, but its treatment is challenging because of its importance to facial esthetics. Supernumerary teeth are the main cause of impaction of upper incisor. Supernumerary teeth when present can cause both esthetic and pathologic problems. Supernumerary teeth in the maxillary midline are common. Early detection of such teeth is most important if complications are to be avoided. We report a case of 12 year old male with an impacted supernumerary tooth in the maxillary anterior region, which wasinterfering with the eruption of the permanent, left central incisor. The impacted supernumerary tooth was surgically removed. With the application of an orthodontic traction, impacted left maxillary central incisor was brought down to its proper position in the dental arch.
