Abstract

Introduction:

The effect of rheumatoid arthritis (RA) on the healing and pathophyisiology of apical periodontitis is unknown because there is no study in the literature evaluating the association of RA with the prevalence of periapical rarefying osteitis (PAR) and endodontic treatment. Therefore, the goal of this cross-sectional study was to evaluate the prevalence of PAR and root canal treatment in RA patients when compared with controlled individuals.

Methods:

Full-mouth radiographs of 131 individuals with RA were examined and compared with 131 controls that were sex and age matched exactly with the diseased group. The total number of teeth, presence or absence of root canal filling, quality of root canal filling, quality of restoration, and periapical status were recorded.

Results:

Overall, the prevalence of teeth with PAR was 4.0% in the diseased group and 3.5% in the control group (P > .05). The prevalence of root canal–treated teeth was 6.2% in the RA group and 5.6% in the control group (P > .05). Controls have significantly more teeth than those with RA (P = .027).

Conclusions:

The prevalence of PAR and endodontic treatment was not significantly different in individuals with RA compared with control patients.
