Objectives: Determine the frequency of restorative procedures, specifically posterior composite restorations (PCR) and root canal treatments (RCT), performed in National Dental Practice-Based Research Network (www.NationalDentalPBRN.org) practices using electronic dental records (EDR) data. To date, restorative PCR and RCT performed in community settings have been studied based on claims data. However, such studies are rare and may also not provide insights on these restorative procedures in practice settings across the US.
Methods: Ninety-nine Network practices that used Dentrix or EagleSoft EDR shared de-identified data of patients who received PCR and/or RCT on permanent teeth from January 1, 2000, through October 31, 2015. Next, we merged and normalized the data from these practices. We calculated the frequency of PCR and RCT performed and the mean age of the patients when they received treatments. We performed descriptive statistics and ANOVA to determine any significant difference between the mean ages of patients across regions.
Results: Table 1 shows the number of PCR and RCT performed in the six network regions. Among PCR, one-surface PCR was the most common procedure performed (44.6%) followed by two-surfaces PCR (40.5%). Patients in the age group 18-44 years received the most number of PCR (44%). Molar RCT ranked highest (51%) among RCT followed by bicuspid RCT (28.5%) and anterior teeth RCT. Patients in the age group 45-64 received the most number of RCT (42%). The mean age at which patients received PCR and RCT were significantly different across regions.
Conclusions: Our preliminary results identified the most common PCR and RCT performed in Network practices and a statistically significant difference in the mean age of patients between the six regions. Ongoing data analysis will determine the longevity of PCR and RCT teeth in practices across the US using these data.
