Talon's cusp in a primary maxillary central incisor A report of a rare odontogenic anomaly

Talon's cusp, a type of dens evaginatus (DE) in a primary tooth, is a rare odontogenic anomaly which is reported sparingly in the literature. We report this case describing the presence of a talon's cusp on the right primary maxillary central incisor in a 2-year-old boy precipitating discomfort, owing to occlusal interference. The treatment plan involved pulpectomy and reduction of the lingula DE extension under general anesthesia.

Prevalence of Developmental Anomalies of Teeth in a Group of Indian Children A Cross Sectional.

Introduction: Developmental anomalies of the tooth areroutinely encountered by paediatric dental professionalsand may present with esthetic and or functional problems.The reported literature has shown a wide variation in theprevalence of these conditions across the globe. Study aimedto assess the prevalence of various developmental anomaliesof tooth in a sample of Indian paediatric populationMaterial and Methods: A total of 3000 children in the agegroup of 6 to 13 years visiting the OPD of pedodontics andpreventive dentistry of BIDSH, Patna were examined clinicalyand radiologicaly when required and the data was tabulated.Descriptive statistics methods were used using SPSS.Results: Prevalence of dental anomalies was 4.86%.in thestudy population and Enamel hypoplasia, hypodontia andtalon's cusp were the most frequently encountered anomalies.The presence of developmental anomalies was a statisticalysignificant finding.Conclusion: Early detection of developmental anomaliesmay prevent future complications and eliminate the need forcomplex therapeutic intervention.

Bilateral Occurrence Of Talon Cusps In Primary Dentition: A Rare Entity

Talon cusps are very common in permanent dentition, while rarely reported in primary dentition. Unilateral is more common than bilateral occurrence of talon cusps and more common in males than females. The occurrence of bilateral occurrence of talon cusps in primary dentition has not been reported very frequently. The purpose of the present case report was to describe a rare case of bilateral talons in 4-year old child.

Multidisciplinary management of a fused maxillary central incisor moved through the midpalatal suture: A case report / 대한치과교정학회지

Fusion of teeth is a developmental anomaly. It occurs at the stage of tooth formation, which determines the shape and size of the tooth crown, when one or more teeth fuse at the dentin level during the morphodifferentiation of the dental germs. Such teeth show macrodontia and may cause crowding, as well as esthetic and endodontic problems. In this article, we report a rare case of a maxillary central incisor fused to a supernumerary tooth showing labial and palatal talon cusps, which was orthodontically moved across the midpalatal suture. A 13-year-old Caucasian boy sought treatment for the unesthetic appearance of his maxillary central incisor and anterior crowding. He was rehabilitated successfully via a multidisciplinary approach involving orthodontic, nonsurgical endodontic, periodontal, and prosthodontic treatments. After a 26-month treatment period, the patient's macroesthetics and microesthetics were improved. The overall improvement of this macrodontic tooth and its surrounding tissues through multidisciplinary treatment was documented using cone-beam computed tomography.

Facial and Palatal Talon Cusp on a Mesiodens Associated with Hyperdontia- A Rare Occurrence.

Supernumerary teeth or hyperdontia are those that are additional to the normal complement of teeth. Mesiodens is an extra tooth most commonly seen in the premaxillary region, while talon cusp is a well demarcated additional cusp extending form cingulum or cemento- enamel junction to the incisal edge. It is usually present on labial or palatal surface of primary and permanent anterior teeth. Occurrence of talon cusp on a mesiodens is an uncommon phenomenon. This paper presents a rare case of facial and palatal talon cusp on a mesiodens in association with hyperdontia, reported in a 12-year old girl.

Mandibular talon cusp - a case report

Talon cusp is a relatively rare developmental dental anomaly, characterized by cusp-like projections from the cingulum area, or cemento-enamel junction of maxillary or mandibular anterior teeth, in both the primary and permanent dentition. In most of the cases it involves maxillary lateral incisors. The anomaly has been reported to be rare especially when it occurs on mandibular teeth. This article reports a case of talon cusp on permanent mandibular central incisor, which makes it a rare entity.

Facial talon cusp on mandibular incisor: A rare case report with review of literature.

Talon cusp is a relatively rare developmental dental anomaly thought to arise as a result of evagination on the surface of a tooth crown before calcification has occurred. It is characterized by cusp‑like projections from the cingulum area, or cemento‑enamel junction of maxillary or mandibular anterior teeth, in both the primary and permanent dentition, usually observed on the lingual surface of the affected tooth. The cusp may or may not contain an extension of the pulp. The etiology remains unknown. The incidence is 0.04‑8%. Any tooth may have a talon cusp but most of the cases involve maxillary lateral incisors. The anomaly has been reported to be rare especially when it occurs on mandibular teeth. This article reports a case of talon cusp on permanent mandibular central incisor that too on facial aspect which makes it a rare entity.

Oculo-facio-cardio-dental syndrome in three succeeding generations: genotypic data and phenotypic features

Oculo-facio-cardio-dental (OFCD) syndrome is a rare X-linked disorder mainly manifesting in females. Patients show ocular, facial, cardiac, and dental abnormalities. OFCD syndrome is caused by heterozygous mutations in the BCOR gene, located in Xp11.4, encoding the BCL6 co-repressor. We report a Croatian family with four female members (grandmother, mother and monozygotic female twins) diagnosed with OFCD syndrome who carry the novel BCOR mutation c.4438C>T (p.R1480*). They present high intrafamilial phenotypic variability with special regard to cardiac defect and cataract that showed more severe disease expression in successive generations. Clinical and radiographic examination of the mother of the twins revealed a talon cusp involving the permanent maxillary right central incisor. This is the first known report of a talon cusp in OFCD syndrome with a novel mutation in the BCOR gene.

An Unusual Case of Talon Cusp On Fused Teeth- A Rare Case Report.

Talon cusp is morphologic-ally well-delineated additional cusp that prominently projects from the palatal surface of primary or permanent anterior teeth and extends at least half the distance from the cementoenamel junction to the incisal edge. Fusion is the union of two adjacent normal tooth germs at the level of dentin during dev-elopment. The association of Talon cusp with fused teeth is not an isolated trait. The aim of this case report is to present same unusual case of Talon cusp on fused primary maxillary incisors emphasize the importance of early diagnosis to avoid complication related with this condition.

Facial Talon Cusp Maxillary Lateral Incisor : A Case Report.

Talon cusp is a supernumerary structure, developmental disturbance in the shape of teeth. Projecting from the cement enamel junction to the variable distance towards incisal edge of the tooth. Commonly occurring on Palatal/Lingual aspects of primary and permanent incisor teeth. Presence of the same on facial aspect of the incisor as an isolated anomaly is rare. This report presents one such case of presence of talon cusp on the facial aspect of a maxillary lateral incisor.

Prevalence and distribution of dental anomalies in 500 Indian school children.

Objective: Developmental disturbances of teeth contribute to dental problems encountered in general practice. These are a group of disorders where prevention is not possible, with the exception of environmental enamel hypoplasia. Surveys done on various populations have found prevalence of dental anomalies to be 5.46%. Knowledge of common dental anomalies when available can be a useful tool for forensic dentistry. Since such epidemiological data is not available for the Jodhpur population in Rajasthan, this study was conducted to determine the prevalence of developmental dental anomalies in 500 school going children. Methodology & Result: A total of 500 school children (290 male & 210 female) of age ranging between 6 - 15 years were examined clinically for developmental anomalies of teeth. Prevalence of Peg lateral, supernumerary teeth & Talon’s cusp was 0.4%, 0.6% & 0.2% respectively while 18.8% showed fluorosis induced enamel hypoplasia.

Permanent mandibular incisor with multiple anomalies - report of a rare clinical case

Permanent mandibular central incisor is rarely affected by tooth shape anomalies of crown and root. Co-occurrence of multiple anomalies in a permanent mandibular central incisor is extremely rare. This paper reports an unusual concurrent combination of multiple dental anomalies affecting both the crown and root of a permanent mandibular left central incisor - talon cusp, dens invaginatus, short root anomaly and macrodontia -, which has not previously been reported together. Case management is described and implications are discussed. The dentist should be aware of these rare entities in order to provide an accurate diagnosis and management for which detailed examination of the tooth both clinically and radiographically is very important.

O incisivo central inferior permanente raramente é afetado por anomalias de forma envolvendo a coroa e a raiz. A co-ocorrência de múltiplas anomalias em um incisivo central inferior permanente é extremamente rara. Este artigo relata uma combinação concomitante incomum de múltiplas anomalias dentais afetando tanto a coroa quanto a raiz de um incisivo central inferior permanente - cúspide em garra (talon cusp), dens invaginatus, anomalia de raiz curta e macrodontia - que ainda não havia sido descrita na literatura. A condução do caso é descrita e suas implicações são discutidas. É importante que o dentista esteja familiarizado com essas entidades raras a fim de proporcionar diagnóstico e tratamento precisos, para os quais exames clínicos e radiográficos detalhados são extremamente importantes.

Concommitant occurance of dens invaginatus and talon cusp: A case report / Ocorrência simultânea de dens invaginatus e cúspide talon: relato de caso

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.

A rare case of multiple talon cusps in three siblings

Talon cusp is an uncommon anomaly, whose etiology may be disturbances in the morphodifferentiation stage. Dens in dente is also a rare anomaly that is challenging in clinic as it may cause pulp necrosis or periapical lesions due to the communication with the oral cavity. This article reports multiple talon cusps on permanent maxillary and mandibular incisors and molars in 3 siblings. A 9-year-old boy presented with structures like nodules, shaped as cylindrical cones with a sharp point or a raindrop with deep developmental fissures on the palatal aspect of the maxillary central incisors, lingual aspect of the mandibular central incisors and labial aspect of both mandibular first molars. The buccal surface of the maxillary right central incisor was also affected. Some of them exhibited dens in dente. His 15-year-old sister had prominent talon cusps on the palatal surface of maxillary central incisors and buccal surface of the mandibular first molars and mandibular left second molar. His 7-year-old brother had only one trace talon on the maxillary left central incisor. No syndrome was identified in the patients. In conclusion, genetic inheritance may be a causative factor in talon cusp.

Cúspide em garra (talon cusp) é uma anomalia incomum, cuja etiologia pode estar relacionada a distúrbios no estágio de morfo-diferenciação. Dens in dente é também uma anomalia rara que impõe desafios na prática clínica, uma vez que pode causar necrose pulpar ou lesões periapicais devido à comunicação com a cavidade oral. Este artigo relata múltiplos casos de cúspide em garra em incisivos e molares superiores e inferiores permanentes em 3 irmãos. Um menino de 9 anos apresentou-se com estruturas nodulares em formato de cone cilíndrico com uma ponta aguda ou de "gota de chuva", com fissuras de desenvolvimento profundas na face palatina dos incisivos centrais superiores, e face lingual dos incisivos centrais e vestibular de ambos os primeiros molares inferiores. A face vestibular do incisivo central superior esquerdo também foi afetada. Alguns dentes apresentavam dens in dente. Sua irmã de 15 anos apresentava cúspides em garra proeminentes na face palatina dos incisivos centrais superiores e face lingual dos primeiros molares inferiores e segundo molar inferior esquerdo. Seu irmão de 7 anos apresentava apenas uma cúspide em garra vestigial no incisivo central superior esquerdo. Nenhuma síndrome foi identificada nos pacientes. Conclui-se que a herança genética pode ser um fator causativo da cúspide em garra.

Multi-lobed mesiodens with a palatal talon cusp: a rare case report

Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch and the talon cusp is a rare dental developmental anomaly seen on the lingual surface of anterior teeth. This paper presents a rare clinical case of development of talon cusp in a mesiodens with multiple lobes, which interfered with both occlusion and appearance of an 11-year-old patient. During clinical interview, the patient reported difficulty on mastication. Clinical and radiographic examination revealed that a supernumerary tooth with completely formed root was causing an occlusal interference. The supernumerary tooth was diagnosed as multi-lobed mesiodens associated with a palatal talon cusp. The treatment plan consisted in the extraction of the supernumerary tooth followed by orthodontic treatment for diastema closure and tooth alignment.

Mesiodens é um dente supranumerário mais comumente visto no arco maxilar na linha média, e a cúspide em garra (talon cusp) é uma anomalia dental de desenvolvimento rara que ocorre na face lingual de dentes anteriores. Este artigo apresenta um caso clínico raro de desenvolvimento de uma cúspide em garra em um mesiodens multilobulado que causava interferência tanto na oclusão quanto na aparência de um paciente de 11 anos de idade. Durante a entrevista clínica, o paciente relatou dificuldade na mastigação. Exame clínico e radiográfico revelou que um dente supranumerário com raiz completamente formada estava causando interferência oclusal. O dente supranumerário foi diagnosticado como sendo um mesiodens multilobulado associado a uma cúspide em garra palatina. O plano tratamento consistiu na extração do dente supranumerário seguida de tratamento ortodôntico para fechamento de diastema e alinhamento dos dentes.
