It usually occurs on palatal and lingual surface of the anterior teeth. On rare occasions the cusp may project from the facial surface or from both surfaces of a single tooth. When it occurs on facial surface of anterior teeth, the prime consideration is aesthetics, plaque retention and function. Regular follow- up is required to avoid any periapical changes. Here we report a rare case of Labial Talon cusp in Maxillary Central Incisor of a 45 year old male patient found incidentally on routine clinical examination.

Introduction Talon cusp is an unusual cuspal projection from an anterior tooth with normal enamel and dentin containing varying degrees of pulp tissue. [1,2] It is otherwise referred to as dens evaginatus, tuberculated premolar, interstitial cusp, occlusal anomalous tubercle, odontoma of the axial core type, occlusal enamel pearl, evaginated odontoma, supernumerary cusp and occlusal enamel pearl, of which dens evaginatus is used for both anterior and posterior teeth [3,4]. Talon cusp was first recorded by Mitchell in 1892. She described this accessory cusp on the lingual surface of a maxillary central incisor as “a process of a horn-like shape curving from the base downward to the cutting edge” in a female patient. This condition was termed by Mellor and Ripaas “Talon cusp” because of its resemblance to an Eagle’s talon [2,4]. The exact etiology of this condition is unknown. Prevalence of talon cusp varies considerably among ethnic groups ranging from 0.06% to 7.7%. The reported prevalence is 0.6% in Mexicans, 7.7% in a northern Indian, 2.5% in a Hungarian, 5.2% in Malaysian, and 2.4% in Jordanian population. [5] It has high predilection for the maxillary teeth over the mandibular teeth and its occurrence is more common in males than females [1,2]. Three fourths of all reported talon cusps are located in the permanent dentition. The cusp predominantly occurs on permanent maxillary lateral (55%) orcentral (33%) incisors but are less frequently on mandibular incisors (6%) and maxillary canines (4%). Their occurrence in the deciduous dentitionis very rare, with vast majority of cases noted on deciduous maxillary central incisors [1]. Talon cusp usually occurs on the lingual surfaces of teeth. On rare occasions the cusp may project from the facial surface or from both surfaces of a single tooth. [1] The frequency of occurrence of labial talons cuspvaries widely in different ethnic groups. According to one study, low prevalence was observed for American children (0.25 %), while in Chinese and Arab populations it was considerably higher(6.9 %). [6] A deep developmental groove may be present where the cusp fuses with the underlying surface of the affected tooth [1]. Here, were port a rare case of Labial Talon cusp in Maxillary Central Incisor of a 45 year old male patient found incidentally on routine clinical examination. 2. Case Report Figure 1.
