What is a talon cusp?
Talon cusp is a rare dental anomaly in which a cusp-like mass of hard tissue protrudes from the cingulum area of maxillary or mandibular anterior teeth. The typical appearance of this projection is conical and resembles an eagle’s talon.
Which syndrome is associated with Talon cusp?
Talon cusp is also seen in association with conditions such as Rubinstein-Taybi syndrome, Mohr syndrome, Ellis–van Creveld syndrome, Incontinentia pigmenti achromians, Berardinelli-Seip syndrome, and Sturge–Weber syndrome.
Is Talon Evaginatus a cusp?
Dens evaginatus is a developmental anomaly characterized by the occurrence of an extra cusp shaped as a tubercle projecting from the palatal or buccal surfaces (talon cusp). In the anterior dentition, dens evaginatus is more commonly found in the maxilla and on the palatal surface of the tooth.
How many people have a talon cusp?
Talon cusps are rare. They’re thought to affect 0.04 to 8 percent of the population, according to a case report in the Oral and Maxillofacial Pathology Journal (OMPJ). A cusp can develop on a baby tooth (also known as primary teeth) but more commonly develops on a permanent tooth.
How do you treat Talon cusp?
Talons cusp treatment mainly involves reduction of the cusp and management of the developmental grooves associated with it. Gradual grinding of the cusp and use of air abrasion allow us to follow the principles of minimally invasive dentistry in treating this anomaly.
Which is the most common type of talon cusp?
Conclusion. Type I talon cusp and type II talon cusp were the most common types and permanent maxillary central incisor was the most commonly involved tooth (50%). An extremely rare case of talon cusp on a fused permanent mandibular incisor is also reported.
Where are talon cusp and dens evaginatus located?
It can be observed as a single malformation or may be associated with other genetic disorders. It is most commonly observed on the palatal surface of the upper lateral incisors followed by the upper central incisors, the lower incisors and then the upper canines.They are mostly seen on the permanent teeth.
Why do I have talon cusp in my milk teeth?
However, some reports state the incidence of talon cusp in milk teeth as well. During the growing phase of the tooth germ, any increase in pressure from the adjacent tooth germs or any other external sources may lead to an out folding of the dental lamina causing the formation of a tooth germ.
