Talon cusp is an uncommon dental anomaly in which an accessory cusp-like structure projects from the cingulum area or cemento-enamel junction of the maxillary or mandibular anterior teeth. This anomalous cusp resembles an eagle's talon. It occurs in both the primary and the permanent dentition. A comprehensive literature review shows that only 37?cases of talon cusps have been reported in the primary dentition, of which only 4?cases report this anomaly on the primary maxillary lateral incisor. Though labial/facial talon cusps have been reported in the permanent dentition, no case of a labial talon has been reported in the primary dentition. We report two females with cleft lip and palate with facial talon cusps on the primary lateral incisor and believe that these are the first cases to be reported. Clinical considerations and debate on the etiology of this anomaly are discussed. 相似文献

CASE REPORT: Talon cusp is an uncommon dental anomaly manifested as an accessory cusp-like structure on the crown of anterior teeth. This report describes two unusual cases of talon cusp. Case 1 showed bilateral anomalous cusps on the palatal aspects of maxillary supernumerary teeth, causing premature contact and tooth impaction. In case 2, a double-fused talon cusp was projected from the palatal surface of a large geminated central incisor. A talon cusp is not an innocuous defect, as it may provide a substantial diagnostic, treatment planning and procedural challenge. Early diagnosis and management are important to avoid complications. 相似文献

The term talon cusp refers to a relatively rare dental anomaly in which an accessory cusplike structure projects from the cingulum area or cement-enamel junction. The condition can occur in either maxillary or mandibular anterior teeth in both the primary and permanent dentitions. This article reports 2 cases of talon cusp affecting consanguineous first cousins: a case of bilateral talon cusps on the permanent maxillary lateral incisors of a 16-year-old girl, and a case of talon cusp on the maxillary permanent lateral incisor of an 11-year-old boy. The talon cusps caused clinical problems that were related to caries or occlusal interferences. The presence of the dental anomaly in 2 members of the same family suggests that genetic inheritance may be a causative (related) factor. Examination of relatives could facilitate early diagnosis of the talon cusp and aid in preventing carious and occlusal problems. 相似文献

Talon cusp is an uncommon malformation. The aetiology is unknown although it is thought to be the combination of genetic and environmental factors. The purpose of the study was to examine the prevalence of talon cusps in children aged 7-18. 600 model casts were examined in the Pedodontic and Orthodontic Department of the Semmelweis University. Classification of talon cusps used was based on the degree of formation and extension by Hattab et al [6]. 12 talon cusps were found in the group of type 1, two were found in group of type 2 and one in type 3. The prevalence of talon cusps was 2.5%, mostly on the upper permanent lateral incisors. In four cases it was bilateral. The prevalence of talon cusps was more frequent in males compared to females. The early recognition of the anomaly is important from the therapeutic point of view (placement of sealant, periodic reduction of the cusp). 相似文献

Talon cusp is a rare developmental extra cusp-like projection on the cingulum area of affected anterior teeth that may cause various functional and aesthetic problems. The present report describes a case of bilateral palatal talon cusps on permanent maxillary incisors and the treatment procedure to overcome the clinical problems associated with talon cusps. 相似文献

Talon cusp on a geminated tooth is a very rare condition. To the best of our knowledge, the literature contains only one case report of a labial talon cusp on a geminated tooth. This is the first clinical report describing a case of bilateral talon cusps on geminated permanent maxillary central incisors associated with dental root shape abnormality and its successful management. 相似文献

Abstract – The talon cusp, or dens evaginatus of anterior teeth, is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cemento–enamel junction. This occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. One of the main problems caused by accessory cusps are occlusal interferences. The anomalous cusp even can generate occlusal trauma and reversible acute apical periodontitis of the opposing tooth. This article reports a case of talon cusp affecting the permanent maxillary left lateral incisor that caused clinical problems related to occlusal trauma and apical periodontitis caused by a premature contact. The treatment of the occlusal interference produced by the taloned tooth is described. 相似文献

Two rare cases of talon cusps in the mandibular incisors were observed during a prevalence study on talon cusp. One of them was seen on a mandibular primary lateral incisor. The other one was observed on the mandibular left permanent central incisor, and the right mandibular permanent central incisor was congenitally missing. There were no associated developmental syndromes with either of the cases reported. Of the 4770 children examined, nine cases had talon cusp with only two rare cases of mandibular talon cusp, one in the primary dentition and the other in the permanent dentition. 相似文献

BACKGROUND: Most reported cases of talon cusps in the primary dentition have been on the maxillary central incisors and the permanent successors have remained unaffected. Four of the five reported cases on a maxillary lateral incisor, however, have been associated with a supernumerary permanent successor. AIM: This paper describes the relationship between the presence of talon cusps on a primary maxillary incisor, and the morphology and number of the permanent successors in a population of Chinese children. DESIGN: The dental records of children diagnosed with a talon cusp on a primary incisor were retrieved for review. The diagnoses took place in a regional school dental clinic in Hong Kong between April 2002 and August 2005. RESULTS: Fifty-eight primary maxillary incisors with talon cusps were found. When the central incisors were involved, 32 of the 35 (91.4%) underlying permanent successors were not found to be associated with any odontogenic abnormalities. When the lateral incisors were involved, however, 18 of the 23 cases (78.3%) showed odontogenic abnormalities, 14 of which were associated with supernumerary teeth. CONCLUSIONS: The present study shows that, when there is a talon cusp on a primary maxillary lateral incisor, a high proportion of the underlying permanent successors can be expected to exhibit odontogenic abnormalities. 相似文献

Talon cusp is a developmental dental anomaly thought to arise as a result of evagination on the surface of a tooth crown before calcification has occurred. The etiology remains unknown. The incidence is 0.04-10%. Any tooth may have a talon cusp but most of the cases involve maxillary lateral incisors, with some instances of bilateral involvement. The anomaly has been reported to be rare in the mandible. This article reports four cases of talon cusp. The first and the second cases describe bilateral involvement of talon cusp on palatal surfaces of maxillary primary centrals; in the third case talon tubercle occurs on palatal surfaces of both maxillary permanent lateral incisors and the maxillary left central incisor and in the last case a talon cusp in the lingual surface of mandibular permanent lateral incisor. 相似文献

Summary. This is a report of two patients with isolated facial talon cusps. One occurred on a permanent mandibular central incisor; the other on a permanent maxillary canine. The locations of these talon cusps suggests that the definition of a talon cusp include teeth in addition to the incisor group and be extended to include the facial aspect of teeth. 相似文献

Talon cusps are uncommon. Although they normally occur on the palatal surface of maxillary incisors, the literature contains two case reports of labial talon cusps. This is the first report describing a tooth with both a labial and a palatal talon cusp and its successful management. 相似文献

Dental casts of fourteen cases of Rubinstein-Taybi syndrome (RTS) were studied. Two exhibited talon cusps, a dental anomaly which is rare in the normal population. Three others exhibited prominent cingula, which were interpreted as representing a tendency toward talon cusp formation. While additional cases should be examined for this anomaly to determine its frequency in RTS, the presence of talon cusps in a suspected case supports that diagnosis. Teeth exhibiting talon cusps are especially prone to caries and often require early treatment if they are to be retained. 相似文献

This paper reviews the nomenclature, prevalence, definition, etiology, association with other dental/anomalies, diagnosis and treatment planning of talon cusp in the primary anterior teeth. Most of the reported cases have involved the primary maxillary central incisors. However, talon cusps on the primary maxillary lateral incisors are associated with high percentages of anomalies in the permanent successors. This paper reported three such rare cases and dentists should be aware of such additional anomalies. 相似文献

Six cases of talon cusp in the primary dentition are reported, bringing to ten the total cases described in the literature. The dental anomaly affected only maxillary primary central incisors, and no succedaneous teeth were affected. None of the ten cases were associated with any abnormal development syndrome. Clinical observations suggest that the incidence of talon cusps in the primary dentition may be not lower than that in the permanent dentition in Chinese children. 相似文献

The talon cusp is a relatively rare dental developmental anomaly characterized by the presence of an accessory cusp-like structure projecting from the cingulum area or cementoenamel junction. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case and should be as conservative as possible. The purpose of this report was to present the case of bilateral talon cusp in primary maxillary central incisors that was successfully managed with conservative therapy. 相似文献

The methods of treatment of talon cusps are reviewed. A case is reported in which a calcium hydroxide pulpotomy was carried out on an upper central incisor with a talon cusp. This was necessary to enable (a) complete reduction of the cusp within a feasible time span, and (b) maintenance of pulpal vitality in order to allow apical development of the immature root. 相似文献

Talon cusp is a developmental dental anomaly, normally located on the palatal surface of the anterior teeth, that can occur in both primary and permanent dentition. The aim of this article is to relate a clinical case of talon cusp that interfered with both the occlusion and appearance of the patient. During anamnesis, the patient told of difficulty masticating. Clinical examination revealed labial inclination of the maxillary central incisors, featuring an overjet of about 5 mm, with interposition of the lower lip and an Angle Class I occlusal relationship. A treatment plan was devised in which gradual grinding of both talon cusps, the fitting of a removable orthodontic device, and clinical and radiographic follow-up were carried out. 相似文献

Talon cusp is an uncommon anomaly seen both in primary and permanent dentition. In most instances they are associated with other clinical problems such as occlusal interferences, poor esthetics and caries susceptibility. Management of such instances requires a comprehensive knowledge of the clinical entity as well as the problems associated with it. Here, we present two cases of talon cusps. 相似文献

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. 相似文献
