The developmental grooves present between the Talons cusp and the palatal surface of the tooth can harbor microorganisms and lead to future caries.
Talons cusp treatment mainly involves reduction of the cusp and management of the developmental grooves associated with it.
Deep stained developmental grooves were observed at the junction of the talon and the palatal surface of the tooth (Figure 1(a)).
It was planned to seal the deep developmental grooves with glass ionomer cement till the time they were eradicated in the process of grinding.
There are three important aspects linked with the conservative treatment of Talons cusp: (i) treating the deep developmental grooves present at the junction of additional cusp and palatal surface of the tooth, (ii) the site of reduction, and (iii) amount of reduction of Talon's cusp.

Talon cusps with deep developmental grooves
need simple prophylactic measures such as fissure sealing and composite resin restoration.
Shallow developmental grooves were present at the junction of the talon cusp with the palatal surface of the affected tooth without any carious lesions.
On the other hand, large prominent cusps may cause clinical problems, including poor aesthetics, occlusal interference, and displacement of the affected tooth, carious lesions in the developmental grooves and pulpal exposure due to cuspal attrition, accidental cuspal fracture, pulpal necrosis, periapicalpathoses, periodontal pockets, tongue irritation and possibility oftemporomandibular joint pain (1, 2, 23, 25).
* The contour of the marginal ridge and developmental grooves, and
The contour of occlusal surface established by the marginal ridges and related developmental grooves normally serves to deflect food from interproximal spaces.
Where there are deep developmental grooves
, simple prophylactic measures such as tissue seeking and composite resin restoration can be carried out.
