Behavioural interventions that have the potential to improve self-care in adults with periodontitis: a systematic review

Aim: To evaluate behavioural and educational interventions used to improve self-care in adult periodontitis patients in comparison with conventional instruction. Methods: A systematic electronic search of empirical studies that were published up to June 2017 using the MEDLINE database was performed. The reference lists of all of the included studies and articles from six separate journals were manually searched. Results: A total of 1806 articles were identified. Six articles fulfilled the inclusion and exclusion criteria. The interventions used in periodontal treatment had theoretical backgrounds of cognitive behavioural approach, self-regulation theory of Leventhal, motivational interviewing and a client self-care commitment model. The control group in each study was described receiving conventional information. The outcomes of the interventions were classified into three categories: 1) clinical findings 2) self-reported self-care and 3) patient evaluations of the intervention. The behavioural intervention groups seemed to perform slightly better than the control groups when clinical outcome measures such as the presence of plaque or number of periodontal pockets were used. Furthermore, behavioural interventions increased patient reported compliance (e.g. effectiveness of self-care and frequency of interdental cleaning). The different behavioural techniques all seemed to work more effectively than conventional instruction. No behavioural technique could be identified superior to the other. Conclusions: The behavioural interventions seem to be beneficial for patient adherence and may therefore improve periodontal treatment success. However, there is a need to further explore the use of different methods in studies with larger sample sizes, longer follow-up times and both behavioural and clinical outcome measures.
