Analysis of postoperative pain after single versus multiple-visit root canal treatment in molars

The number of visits to root canal treatment is still controversial especially on postoperative pain in molars. Therefore, it is of interest to compare pain outcome of single-visit and multiple-visit root canal treatments in 120 cases of molar root of a tooth. The intensity of pain was measured throughout 7 days with the help of the Visual Analog Scale, analgesic use and treatment success was also measured. Single-visit cases depicted a small difference in pain at 6 hours, but not after and the same level of success at 6 months. Single and multiple visit treatment offer similar postoperative comfort and superior clinical outcomes.
