Assessing the association between receipt of dental care, diabetes control measures and health care utilization

The literature contains few studies regarding the relationships between receipt of regular dental care and medical outcomes for people with type 2 diabetes.The authors compared hemoglobin A(1c) (HbA(1c)) levels (7 percent versus7 percent), low-density lipoprotein cholesterol levels (100 milligrams/deciliter versus ≥ 100 mg/dL) and diabetes-specific hospital admissions and emergency department (ED) visits (one or more visits versus no visits) in 493 people with type 2 diabetes who received regular dental care (≥ two prophylactic visits, periodontal treatment visits or both during a 12-month period) with measures in 493 people with type 2 diabetes who did not receive any dental care. The authors matched patients, all of whom had private medical and dental insurance benefits during the study period, with regard to age, sex and previous utilization of ED visits and hospital admissions, and they followed them for three years.The authors analyzed the data by using multiple logistic regression, which showed that receipt of regular dental care was associated with lower diabetes-specific ED utilization (odds ratio [OR] = 0.61, 95 percent confidence interval [CI] = 0.40-0.92) and hospital admissions (OR = 0.61, 95 percent CI, 0.39-0.95) after they adjusted for age, sex, previous hospital admissions, previous ED utilization, race, baseline HbA(1c) values, Charlson comorbidity index score, body mass index status, periodontal risk status and primary care utilization. The authors found no significant association between receipt of dental care and control of HbA(1c) levels.The study results show an association between regular receipt of dental care and reduced diabetes-specific medical care utilization (that is, ED visits and hospital admissions).Although the results of this study could not show causality, they suggest that receipt of dental care may reduce diabetes-specific health care utilization. Prospective studies are needed to better understand the relationship of receipt of dental care with diabetes control and health care utilization measures.
