An unusual case of talon cusp on geminated tooth

A rare case of talon cusp on geminated permanent central incisor is described. These developmental anomalies cause clinical problems including unsightly dental appearance, occlusal interference, displacement of the affected tooth, attrition, periodontopathy, irritation of the tongue, loss of space and malocclusion. Clinical and radiographic characteristics of these anomalies and modes of treatment are presented. Recognition of this condition and early diagnosis are important to avoid complications.     

An unusual presentation of talon cusp: a case report

The talon cusp is a relatively rare dental developmental anomaly characterised by cusp-like projections, usually observed on the lingual surface of the affected tooth. Normal enamel covers the cusp and fuses with the lingual aspect of the tooth. The cusp may or may not contain an extension of the pulp. This occurs in either maxillary or mandibular anterior teeth in both the primary and permanent dentition. This study reports the unusual case of a 47-year-old female with a taloned tooth on the right maxillary central incisor possessing both lingual and labial talons, with an x-shaped appearance when viewed occlusally.     

Mandibular talon cusp: a case report

Talon cusp is a rare dental anomaly, especially when it occurs on mandibular teeth. A case of talon cusp on a permanent mandibular central incisor is described and illustrated. This case was associated with periodontitis, but was otherwise symptom free.     

Labial and palatal talon cusps on geminated tooth associated with dental root shape abnormality: a case report

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.     

Clinical problems associated with unusual cases of talon cusp

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.     

Bilateral talon cusp: case report.

Talon cusp is an uncommon condition often present in the maxillary incisors and mandibular premolars. Morphologically, this anomaly has a well-delineated cusp that extends at least half the distance from the cementoenamel junction or cingulum area to the incisal edge. 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. Presented is a case of bilateral bifid talon cusp in maxillary central incisors that was successfully managed with conservative therapy.     

Dens invaginatus on a geminated tooth: a case report

AIM: To present a case of a concomitant occurrence of dens invaginatus (DI) and gemination in a mandibular left lateral incisor. BACKGROUND: DI is a developmental anomaly resulting from the invagination of a portion of a crown in the enamel organ stage of odontogenesis. It is commonly found in the maxillary lateral incisors but also occurs in the central incisors, premolars, canines, and molars in descending order of frequency. The occurrence of DI in the mandible is extremely rare. Gemination results from one tooth bud attempting to split into two. Geminated teeth present with a single root structure and rarely occur in mandibular teeth. REPORT: A 13-year-old girl presented with a chief complaint of spontaneous nocturnal pain in the mandibular left lateral incisor tooth. Intraoral examination revealed the tooth was enlarged with a notch on the incisal edge extending to the coronal 1/3 of the crown. The radiological examination revealed a Type 2 DI in a Type I geminated mandibular left lateral incisor. SUMMARY: DI is clinically significant due to the possibility of the pulpal involvement; pulpitis, necrotic pulps, and chronic periapical lesions are often associated with this anomaly without clinical symptoms. Clinicians should be mindful of the possibility of DI when a tooth presents pulpitis without history of trauma or caries and examine the suspicious tooth and the periodontium radiographically.     

Labial talon cusp on permanent central incisor: a case report

Talon cusp is a supernumerary crown structure, a developmental disturbance in the shape of teeth that causes various diagnostic, functional and esthetic problems. Some synonyms for talon cusp are dens evaginatus of anterior teeth, interstitial cusp, tuberculated tooth, odontoma of the axial core type, evaginated odontoma, enamel pearl, supernumerary cusp etc. The lingual location on incisors, which frequently affects occlusion, is pathognomonic of the talon cusp. This report describes a rare odontogenic, isolated anomaly rather than an integral part of any disorder, a case of talon shaped cusp projecting from the labial surface of a maxillary permanent central incisor.     

Management of a case with bilateral talon cusp in primary dentition

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.     

Unusual presentation of talon cusp: two case reports

Talon cusp is an uncommon odontogenic anomaly comprising of an accessory cusp-like structure, usually observed on the palatal surfaces of maxillary incisors. Two uncommon presentations of talon cusp, occurring on a mandibular incisor and on a supernumerary tooth in the maxilla, are reported.     

Bilateral gemination with talon cusp: report of case

The extraction of the geminated maxillary central incisors was selected as the preferred treatment in this case because of the impossibility of properly recontouring these teeth. Although the crowns could have been reshaped somewhat to conform to a more normal size and shape, the roots were so wide that approximation of the central and lateral incisor crowns would have been impaired. The use of normally shaped, large lateral incisors in place of abnormal central incisors gives a better occlusion and a more esthetic result at the end of the treatment.     

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.     

Atypical presentation of bilateral supplemental maxillary central incisors with unusual talon cusp

Delayed eruption of maxillary permanent central incisors in a child poses a distressing esthetic quandary to parents, by virtue of its location in the dental architecture. Well-aligned anterior teeth add confidence to smile and have enhanced self-esteem, which is critical even in early life. Impaction of the maxillary central incisors compared to third molars or the canines is less reported; bilateral supplemental maxillary central incisors related to impacted permanent maxillary central incisors are rare and one of the supplemental central incisors showing unusual talon is still infrequent. A case of impacted maxillary permanent central incisors related to supplemental maxillary central incisors, with one of them showing an unusual talon cusp, is presented.     

Dental management of a talon cusp on a primary incisor

There are many treatment options for the pediatric patient with a talon cusp (TC). The purpose of this paper was to report the case of a TC involving a primary maxillary right central incisor in a 14-month-old male causing displacement of the affected tooth. The etiology of a TC is thought to be a disturbance during the morphodifferentiation stage of tooth development. Clinical problems include: (1) occlusal interferences; (2) esthetic disturbances; (3) accidental cusp fracture; (4) tongue irritation; (5) nursing difficulty; (6) caries; and (7) displacement of the affected tooth. The TC affecting the central incisor was reduced over a period of 4 visits, followed by immediate placement of a 5% sodium fluoride varnish at the conclusion of each reduction visit. Restoration of esthetics and function was evident within 1 month following complete cusp reduction. There were no clinical signs of any problems related to the reduction, and the prognosis was considered to be guarded. The pediatric patient was placed on a 6-month oral hygiene maintenance follow-up.     

Unusual case of bilateral talon cusp associated with dens invaginatus

CASE REPORT: This paper presents a rare case of bilateral talon cusp in permanent maxillary central incisors, one on the labial and another on the lingual surface of each tooth. The condition was associated with dens invaginatus in a maxillary permanent lateral incisor, but no developmental syndrome was identified. The left central incisor required no treatment because the aesthetic appearance was satisfactory and neither occlusal interferences nor caries were present. After careful investigation of the right lateral incisor, a sealant was applied. Root canal treatment was indicated for the right central incisor that had a wide open apex with thin, weak, divergent walls, and an apical radiolucency.     

Facial talon cusp in primary maxillary lateral incisor: a report of two unusual cases

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.
