Psychologic aspects of patients with oral lichenoid reactions.

Psychologic aspects of 49 patients with oral lichenoid reactions (OLR) in contact with amalgam fillings were studied and compared with an age- and sex-matched control group. Psychologic factors such as personality, psychologic functioning, and quality of life were determined by using the Karolinska Scales of Personality (KSP), an additional Personality Scale (PS), a Psychological Functioning Scale (PFS), and a Quality of Life Scale (QLS). With regard to personality the OLR patients had significantly higher scores on the muscular tension and suspicion scales and significantly lower scores on the indirect aggression scale. In addition, the OLR patients were significantly more worried about their health and more helpful. With regard to psychologic functioning the OLR patients had significantly more sad thoughts, became dizzy more easily, found it harder to imagine themselves free from anxiety, and had more difficulty in concentrating. The results indicated that OLR patients had a tendency to be depressive. The need for a systemic investigation including odontologic, medical, and psychologic aspects was expressed.
