Effect of Patient Education on Drinking Behaviour and Oral Hygiene in Patients Undergoing Bariatric Surgery

Both caries and periodontitis are more prevalent among people with obesity. At the same time, we know that bariatric surgery is associated with poorer oral health expressed by caries, enamel erosion and short-term increased inflammation in the gums. Although we do not yet have evidence to determine causality, we suspect that oral health in bariatric surgery patients is further impaired by both systemic effects (hyposalivation, altered oral microbiome, reflux and vomiting) and by altered eating and drinking patterns after surgery (acid exposure with subsequent demineralisation of tooth enamel).

The patient's own diet and oral hygiene can be an opportunity to prevent or slow down such oral problems, but requires personal effort and must be a special focus in patient education.

Patient education is one of the hospital's statutory duties, but the quality of patient education is rarely systematically investigated. This project investigates the effect of three alternative educational interventions on patients' drinking habits, oral hygiene routines, knowledge level and oral health. The three interventions are a website with adapted patient information, group-based education given by healthcare professionals, and distribution of relevant product samples to maintain oral hygiene. Patients are randomised between the different educational interventions.
