Various clinical studies have been conducted using oral stereognosis to assess oral perception and speech in cleft palate patients and in patients who are excessively aware of the presence of dentures and retch.6 This test has also been applied in dentate and edentulous subjects, to study oral muscular ability in different age groups, as an aid to prosthetic treatment planning, in edentulous subjects rehabilitated with complete removable dentures, and as an assessment to denture adaptability.7 More recently studies have been conducted in edentulous patients with Stroke and Parkinson's disease.8 Scarce data are available on oral stereognostic ability in hypodontia patients.
Oral stereognostic ability tests6,16 were conducted on the hypodontia patients and controls.

Oral stereognostic ability is a good diagnostic tool in the evaluation of sensory and motor functions of oral cavity.
