Abstract
AIM: To (i) investigate the frequency and characteristics of pain and discomfort associated with root filled teeth in adult patients regularly attending the Public Dental Service in Örebro County, Sweden; (ii) assess the association between symptoms and clinical and radiographic findings; and (iii) explore the impact of pain and discomfort from root filled teeth on daily life. METHODOLOGY: Patient records of adult patients (≥20 years) scheduled for routine check-ups in April 2015 were screened to identify individuals with root filled teeth; all patients with ≥1 root filled tooth were asked to participate. The examination comprised of clinical and radiographic examinations and questionnaires on general health, on pain symptoms from root filled teeth and on the impact of pain on daily activities. In a general estimating equation (GEE), examination findings and patient-related factors were independently analysed in relation to the outcome 'presence of pain'. RESULTS: In total, 550 patients with 1256 root filled teeth participated. Fifty-three patients (9.6%) experienced pain or discomfort from 62 (4.9%) root filled teeth. Lower age, percussion tenderness and apical tenderness were significantly associated with pain (P > 0.001 to P = 0.044). The average pain intensity was 2.1 on a (0-10) Numeric Rating Scale, and average duration was 28.4 months. The impact on daily life was low. CONCLUSIONS: On average, pain associated with root filled teeth was of mild intensity, >2 years of duration and had low impact on daily life. Although the significantly associated clinical findings may indicate apical periodontitis as the most probable explanation in some teeth, the origin of pain from root filled teeth remains partly unexplained.
