This prospective study investigated the frequency and intensity of postoperative pain and identified associated factors in adolescents undergoing two‐visit root canal therapy. Sixty‐four patients aged 11 to 18 years old presenting with molars with pulp necrosis were assigned consecutively to two visits (plus an interappointment dressing using calcium‐hydroxide paste). Pain intensity was recorded on a visual analogue scale (VAS) of 0–5. Data were analysed using multivariate logistic regression. The frequency of postoperative pain was 32.8% (21/64), with intensities of VAS 1 and VAS 2 in 81%, VAS 3 in 14.3% and VAS 4 in 4.7% of the 21 cases in which it was experienced. Spontaneous preoperative pain (odds ratio (OR) = 6.60; 95% confidence interval (CI) = 1.61–26.97; P = 0.009) and absence of apical perodontitis (OR = 5.65; 95% CI = 1.34–23.87; P = 0.01) were associated with postoperative pain. The frequency of postoperative pain was high, but the intensity, in general, was low, including flare‐ups. The presence of spontaneous preoperative pain and absence of apical periodontitis increase the probability of suffering from postoperative pain.
