Objectives The aim was to study self-image the level of psychological symptoms in patients with symptoms attributed to their dental restorative materials, one group with local oral symptoms only (LSO) and one group with multi-symptoms (M-S).
Materials and methods A questionnaire was sent to the 257 participants, 189 women and 68 men, containing questions regarding their dental and medical history.The self-image was assessed with the Structural Analysis of Social Behavior (SASB. Psychological symptomssuch as somatization, depression and anxiety were assessedand the Global Severity Index (GSI) was computed by using the Symptom Check List 90 (SCL-90).
Results The SASB showed that the M-S group and the LSO-group scored significantly higher on the “spontaneous” and “positive self-image” than the reference group. In the SCL-90, the M-S group scored significantly higher than the LSO-group and the references on the somatization subscales. On depression, anxiety and the GSI scale, the M-S group scored significantly higher than the reference group.
Conclusions The two subgroups rated significantly higher on the SASB Spontaneous and Positive clusters which indicates that these patients have an excessively positive self-image, are very spontaneous and have an overconfidence in themselves compared to the reference group. In the M-S group there was a clear tendency to somatization, depression and anxiety and they are more psychologically stressed than the reference group.
Clinical relevance Clinicians should be aware of that illness attributed to dental restorative materials seems to be multi-factorial and patient with multi-symptoms are more psychologically stressed than patient with local-symptoms only.
