1. Talon's cusp

2. General information
• It projects lingually from cingulum area of
maxillary and mandibular teeth or it is an
anomalous hyperplasia of cingulum on the
lingual surface of maxillary and mandibular
incisors, resulting in the formation of
supernumerary cusp

3. Pathogenesis
• Focal proliferation of tissue during
development
• Exuberant development of the fourth lobe
that is Cingulum may occur

4. Clinical features
• Common in both dentitions.
• Commonly seen in maxillary lateral and Central incisor
• It resembles like an Eagle's Talon
• There is a deep developmental groove where the cusp
blends with sloping lingual tooth surface
• Composed of normal enamel dentine and contains a
form of pulp tissue
• May or may not contain pulp horn
• Patients can face the problems with aesthetic
• Associated with Rubinstein-Taybi syndrome and Sturge-
Weber syndrome

5. Radiographic features
• Superimposed with incisors on which it occurs
• outline is smooth and a layer of normal
appearing enamel is distinguishable

6. Diagnosis
• T shaped elevation on tooth will easily
diagnosed Talon cusp

7. Management
• Prophylactic restoration of the group should
be done to avoid early carious lesion
• Removal of cusp followed by endodontic
therapy
• Periodic grinding and after grinding exposed
dentine should be coated with desensitising
agents
