Presence Of Talon Cusp Research Articles

Talon cusp on palatally erupted mesiodens

Talon cusp is an accessory cusp-like structure or an extra cusp on an anterior tooth arising as a result of evagination on the surface of the crown before calcification has occurred. The cusp is composed of normal enamel and dentin containing varying extensions of pulp tissue. It is associated with few developmental anomalies such as peg laterals, dens invaginatus, and mesiodens. Mesiodens is a supernumerary tooth located in the premaxillary central incisor region which is supplemental or rudimentary type. Association of mesiodens with talon cusp is a rare occurrence with 25 cases reported. The presence of Talon cusp or a supernumerary tooth – mesiodens – leads to clinical implications such as poor esthetics, crowding, rotations, and also occlusal discrepancies. In this report, we present a case report of an 18-year-old male having a talon cusp on palatally erupted mesiodens.

Facial Talon Cusp in Maxillary Lateral Incisor-A Rare Case Report

Talon cusp is a rare developmental abnormality of the tooth characterized by presenting usually on the palatal/lingual surface of anterior teeth as a cusp like projections. The crown of the tooth is covered by normal enamel and dentin, with a cusp like projection that may or may not contain an extension of pulp. Presence of talon cusp on the facial surface of an anterior tooth is rare and literature shows that only few cases have been reported earlier. In this case we present a facial talon cusp on the maxillary right lateral incisor of a 15 year old girl.

Evaginated odontome on maxillary lateral incisor and #8212;a reverse and a rare presentation

Evaginated odontome or talon cusp is an uncommon dental anomaly with accessory cusp-like projection arising from the cingulum area of the maxillary or mandibular anterior teeth. This anomalous cusp resembles an eagle's talon and hence the name. It occurs in both the primary and the permanent dentition. The presence of talon cusp on the lingual surfaces of primary permanent teeth is considered to be pathognomic, but the case reported here is an unusual case which is present in the facial aspect in a female patient. As per the existing literature only seven case reports of facial talon in permanent maxillary teeth have been reported.

Talon cusp on mesiodens: A report of two cases

Talon cusp is a relatively uncommon developmental anomaly usually involves maxillary permanent lateral incisors. Mesiodens is the most common supernumerary tooth present in the palatal midline between the two maxillary central incisors. Both talon cusp and mesiodens are clinically significant developmental alterations giving rise to a variety of complications. The presence of talon cusp on supernumerary teeth is very rare. Till date very few cases have been reported in the literature. This paper describes two cases of talon cusp on the palatal surfaces of supplemental mesiodens. Both the patients reported for unsightly dental appearance and non-eruption of maxillary permanent central incisor. Here we extracted the anomalous teeth to facilitate eruption of permanent maxillary central incisor. Early diagnosis and management are important to avoid complications.

Talon cusp: A case report with management guidelines for practicing dentists

Introduction: Talon cusp is an uncommon odontogenic anomaly which most frequently affects maxillary permanent incisors. Its presence causes the problem in esthetics, prevention of caries, and occlusal accommodation for the patient and problems in the diagnosis and clinical management for the dentist. Case Report: This article reports a case of talon cusp on the palatal surface of the permanent maxillary central incisor. Discussion: Since, the presence of talon cusp usually demands that definitive treatment be instituted; it represents a problem of clinical significance. The dentist should be able to diagnose it as the maxillary incisor is also the principal site for supernumerary tooth.

Oral and Dental Manifestations in Rubinstein-Taybi Syndrome: Report of a Rare Case

Rubinstein-Taybi syndrome, or broad thumb-hallux syndrome, is a well-defined rare congenital disorder characterised by postnatal growth deficiency, craniofacial dysmorphism, broad thumbs and great toes, and mental retardation (intellectual disability). Occurrence may be either sporadic or through autosomal dominant inheritance. Reports of Rubinstein-Taybi syndrome are scarce in the literature. This case report describes the oral and dentofacial findings of Rubinstein-Taybi syndrome affecting a 13-year-old Indian female, including the uncommon presence of talon cusps and an unerupted supernumerary tooth.

Talon cusp in Malay primary teeth: expression, frequency, covariates and treatment needs

The expression and frequency of a morphological variant of maxillary anterior teeth known as the ‘talon cusp’ is reported in a sample of 142 Malay schoolchildren from Yogyakarta, Indonesia. The trait exhibits variable and unilateral expression in the maxillary right lateral incisors of three children, yielding a frequency of 2.1%. Trait expression was graded in nature with males exhibiting larger talon cusps (Type 1, full talon; and Type 2, large semitalon) than the affected female (Type 2, small semitalon). A comprehensive analysis of the Malay primary dentition was conducted to detect possible morphometric covariation with talon cusp. Individuals with talon cusp are not significantly different from unaffected individuals in buccolingual crown size or in primary molar crown morphology. However, two of three individuals with talon cusp possess maxillary and mandibular primary canine teeth with an unusual conical crown structure. While talon cusp has previously been reported to co-occur with supernumerary teeth, including mesiodens, this is the first report of an association with cone-shaped primary canines. We address the infrequent expression of talon cusp in primary maxillary lateral incisor teeth, the presence of talon cusp in earlier and prehistoric populations, the analogous anthropological trait known as tuberculum dentale, and the treatment needs of patients with talon.

The relationship between a primary maxillary incisor with a talon cusp and the permanent successor: a study of 57 cases

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. 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. 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. 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. 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.

Talon cusps: A dental anomaly in the Rubinstein-Taybi syndrome

Dental casts of fourteen cases of Rubinstein-Taybi syddrome (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.
