The sub,variables that were related to interappointment emergencies are in italic typeface. P-values ≤ 0.05 were considered significant.Seventy-seven of the 719 patients included in this study (10.7%) registered interappointment emergencies. The majority of interappointment emergencies occurred within two weeks following intervention (Table 3). The incidence of interappointment emergencies in the cohort of patients who received no intracanal medicament was 11.9% (46/385) compared to 9.3% (31/334) in the cohort of patients who received calcium hydroxide intracanal medicament (odds ratio=1.33, 95% confidence interval 0.82 – 2.15; p=0.249). Also after correction for the variables that were related to interappointment emergencies and could have influenced the findings, no association was found between omitting the use of calcium hydroxide intracanal medicament and interappointment emergencies (Table 4).
