Flare-up incidence and related factors in adults

The study determined the incidence of flare-up and the effect of visit type, treatment duration, pre-operative pain, etc. on flare-up in adults. One hundred and seventy five participants, aged 18 to 60 years with a necrotic central incisor, with or without pre operative pain, participated in the study. They received post operative paracetamol tablets and were asked to report back if unbearable pain/swelling developed. A 10 % flare up rate was recorded, while none of the studied factors had a significant relationship with flare-up, except intra operative pain. Key words: Flare-up, preoperative pain, treatment duration, visit type
