Aims: The aim of the study was to evaluate and compare the oral stereognostic ability and satisfaction for fixed prosthesis in human being. Materials and Methods: The present study was carried out on 40 subjects, the purpose being to investigate the relation of oral perception to diagnostic and therapeutic procedures. Two types of cast metal crowns-one had morphology closely resembling original tooth and other one confirmed to ideal contours were constructed on endodontically treated posterior tooth. One cast metal crown was randomly selected from two cast metal crown and fitted on prepared tooth. Oral stereognostic score of subject was determined by correct response to questionnaire based on the recognition ability of subjects. Patient satisfaction level was checked by psychometric parameter Likert scale. Same procedure was repeated with other type of cast metal crown. Results: Data obtained were compared by paired and unpaired two sample t-test. Oral stereognostic score and satisfaction score were found to be higher for cast metal crown with morphology resembling to original tooth due to recognition and discriminatory ability of subjects and recall-memory. Oral stereognostic level was found to be higher in younger than older subjects. The level of satisfaction was found to be higher in older subjects than younger subjects. Conclusion: It was concluded that acceptance of fixed prosthesis is not only based on dentist's routine procedure of treatment and patient's judgment about oral health, function, and esthetics, but also depends upon patient's oral perception and discriminatory skill for external morphology of fixed prosthesis.
