Abstract

Objectives: This registry-based study aimed to describe cross-sectional dental and demographic data with focus on diagnosis and treatment of periodontal disease. A second aim was to analyse the extent and content of performed periodontal treatment in patients with varying degrees of periodontitis and if treatment was provided on equal terms. An additional aim was to identify if possible differences in treatments were related to type of dental insurance system.

Methods: A study population, 225,913 individuals ≥ 20 years living in the Region of Västra Götaland, was identified by the Swedish Quality Registry for Caries and Periodontal Diseases (SKaPa). Registry data were retrieved for the period 2010-2012. Logistic regression models were used to predict the probability of receiving periodontal interventions and access to fixed annual fees.

Results: Among the study population, 17% had periodontal disease (≥ 4 teeth with periodontal pockets ≥ 4 mm) and constituted the final study sample. The probability of periodontal intervention increased with severity of periodontitis, in moderate (OR = 2.3) and severe cases (OR = 5.2) compared to the group with minor disease (p < 0.001). Severe periodontitis was associated with male gender, increasing age and smoking. About 30% of the individuals remained untreated over the 3-year period. Individuals with fee-for-service were more likely to receive periodontal intervention than individuals with fixed annual fees (OR = 1.7; p < 0.001).

Conclusion: Severe periodontitis and being in the fee-for-service system were associated with more periodontal interventions. However, one-third of the study subjects remained untreated. These findings indicate the need for improved care on equal terms for patients with periodontal disease.
