title: Flare-up rate in molars with periapical radiolucency in one-visit vs two-visit endodontic treatment.
abstract: OBJECTIVE
  The objective of this study was to compare postobturation flare-ups following single and two-visit endodontic treatment of molar teeth with periapical radiolucency.
  
  
  METHODS
  A total of 100 patients with asymptomatic molar teeth with periapical radiolucency were selected. They were randomly allocated into two groups. Fifty patients received complete endodontic treatment in one-visit. Fifty patients received treatment by debridement and instrumentation at the first visit followed by obturation at the second visit.
  
  
  RESULTS
  10% of patients had flare-ups in the single visit group and 8% of patients had flare-ups in the two-visit group. Number of visits did not affect the success of endodontic treatment (p>0.05). Age, gender and tooth type had no effects on the occurrence of flare-ups regardless the number of visits (p>0.05).
  
  
  CONCLUSIONS
  One-visit endodontic treatment was as successful as two-visit endodontic treatment as evaluated by rate of flareups in asymptomatic molar teeth with periapical radiolucency.
