A study of flare-ups following single-visit root canal treatment in endodontic patients.


OBJECTIVE To determine the frequency of flare-ups in single-visit endodontic treatment and the associated factors. STUDY DESIGN Observational. PLACE AND DURATION OF STUDY Baqai Dental College Hospital, Karachi, from November 2005 to May 2006. METHODOLOGY One hundred patients were assigned for single-visit root canal treatment. Patients that defaulted after the first appointment (incomplete treatment) were excluded from the study. For each tooth treated, the clinical factors and conditions existing before and after the completion of treatment were recorded. This data included patient's age, gender, type of tooth, pre-operative status of pulp and periapical tissues and recording pain and swelling (flare-ups) postoperatively after 1 day, 7 days and 1 month. The significance of results was obtained by applying paired-sample t-test and Pearson X2 test. RESULTS Three of one hundred cases showed flare-ups after treated in single appointment. On the other hand, a marked number (n=97) of cases did not show flare-ups during the study period. None of the studied variables showed any statistically significant bearing on rate of flare-ups in single appointment root canal treatment. CONCLUSION The single-visit root canal treatment was safe in terms of endodontic flare-ups as far as results of this study are concerned. It was safer in both vital and non-vital teeth, and even in teeth with periapical pathosis.
