Shallow developmental grooves were present at the junction of the talon cusp with the palatal surface of the affected tooth without any carious lesions.
DISCUSSION: Talon cusp was reported by Mitchell et al in 1892 and was given the name talon cusp by Mellor talon.
An unusual case of talon cusp on a geminated tooth.
Cubukcu CE, Sonmez A, Gultekin V Labial and palatal talon cusps on geminated tooth associated with dental root shape abnormality: a case report.
Dental anomalies in the primary dentition associated with talon cusp of non-cleft and non-syndrome patients, are rare.
Talon cusp is not an integrated part of any specific syndrome, but appears to be more prevalent in the permanent dentition in patients with Rubinstein-Taybi syndrome (broad thumb-hallux syndrome), Mohr syndrome (oral-facial-digital syndrome, type 2), Sturge-Weber syndrome (encephalotrigeminal angiomatosis), and incontinentia pigmenti achromians.
Prevalence of talon cusp has been found to be less than 1% of population.
Talon cusp may occur either alone or along with other anomalies like mesiodens, odontome, unerupted or impacted teeth, peg shaped maxillary incisors, dens invaginatus, cleft lip and disordered nasal alae, gemination, fusion and supernumerary teeth.
12 Diagnosis of talon cusp teeth was determined by means of an intraoral examination.

Millor and Ripa (1970) (13) coined the term talon cusp
because it resembles an eagle's talon in shape.
