**5. Psychological classification and interpretation**

Evaluation of mental attitude of patients has been an important aspect in clinical case history in Prosthodontics. Various authors like House, Heartwell, Sharry, Gamer et al and others have classified patients based on evaluation of psychological status [8].

This approach may be used for the conventional prosthodontic patient, however in patients with disfigured orofacial region or altered biological function like speech or swallowing it may not hold valid due to the impact being much stronger. In such patients, underlying deep seated emotional distress may get exaggerated. Further, in such an individuals it is critical for the prosthodontist to assess the mental status of the patient, need for referral and modification of treatment modality best suited for the patient.

**It becomes paramount that the prosthodontist understand the various psychological diagnoses, ranging from subtle emotional distress to overt psychological disorders, that potentially undermine successful prosthodontic**  **treatment. For example, if a patient taken up for Prosthodontic rehabilitation, but shows frequent bouts of crying or abrupt temper tantrum is indicative of a depressive mental state or altered psychological condition including panic disorder, obsessive-compulsive disorder (OCD), posttraumatic stress disorder (PTSD), mood disorder or a bipolar state. This may hint the treating prosthodontist for the need of intervention of psychologist or a psychotherapist for better treatment outcome.**
