GOTHENBURG, Sweden: Obesity is a medical concern that may lead to numerous health problems, including diabetes and cardiovascular disease. A recent study carried out at the University of Gothenburg for a doctoral thesis has also shown that patients who had undergone surgical treatment for obesity had greater dental caries frequency and poorer oral health. The study offers important insights into patients’ oral health before and after bariatric surgery and could contribute to more effective preventive dental care for this group of patients.
