Persons in this study consisted of 130,546 United Healthcare commercial dental and medical members between the ages of 18 and 65. Net medical costs for members who received dental care, such as periodontal treatment or an oral prophylaxis, was on average $1,037 lower than medical costs (or $701 when including drugs) for members who received other or no dental care, such as extractions, root canals, restorative treatment, other dental claims or no dental claims, after adjusting for the extra expense of the dental care. The largest medical savings ($1,849 for just medical or $1,706 including Rx) were for members who were not medically compliant with their disease management program and received dental care after adjusting for the extra expense of the dental care. Members who were medically compliant with their disease management program and received dental care achieved an average net savings of $264.
A Medical Dental Integration Study was published by United Healthcare March 2013.(1) The study, which was a performed by Optum, a health services company, on behalf of United Healthcare, evaluated the impact of several dental treatments on medical and pharmacy costs for individuals with chronic medical conditions.(2) Results are divided by chronic condition as well as by whether or not individuals were compliant with managing their chronic condition. This removes compliance bias from the study. An additional analysis was performed on chronic conditions that are comorbid with diabetes.
