The use of a psychological testing instrument as an indicator of dissatisfaction with aesthetic dental treatment – a preliminary study
Background: The use of psychological testing to indicate the potential for dissatisfaction with dental treatment has many potential patient and clinician benefits but has been rarely investigated. The study aimed to explore the use of the Symptom Checklist-90-Revised (SCL-90-R) psychological testing instrument in describing the relationship between pre-treatment psychological traits and aesthetic restorative treatment satisfaction. Methods: Thirty patients requiring aesthetic restorative dental treatment completed three questionnaires, namely 1) a pre-treatment expectation assessment, 2) an SCL-90-R analysis pre-treatment and 3) an outcome assessment post-treatment to assess patient’s expectations and satisfaction of the proposed dental treatment relating to function, aesthetics, comfort and tissue preservation. Logistic regression models were used to assess the impact of psychological variables on patient satisfaction after adjusting for baseline expectations (P < 0.05). Results: The satisfaction for the aesthetic component of treatment was significantly associated with psychoticism and positive symptom distress index. The satisfaction for the comfort component of treatment was significantly associated with obsessive compulsive symptoms, depression and anxiety. Following adjustment for baseline expectation, tissue preservation satisfaction was associated with somatization, obsessive compulsive, interpersonal sensitivity, depression and global severity index. No baseline psychological measures were significantly associated with chewing satisfaction. Conclusions: The SCL-90-R shows initial promise in assisting clinicians to identify and understanding patients who have a high risk of dissatisfaction with aesthetic dental treatment. The ability to indicate aesthetic restorative treatment dissatisfaction is of great benefit to clinicians in maximising success and mitigating risk.
