Abstract
Postoperative hypersensitivity is described as a sensation of pain in a tooth or teeth trigerred with with sensitivity to hot, cold, and sweet stimuli or mastication one week or more post -restoration. While pain during clenching suggests restoration in hyperocclusion, pain during chewing is regarded as postoperative hypersensitivity associated with polymerization shrinkage and gaps between dentin and the fluid filled restoration, which causes tooth hypersensitivity as the fluid slips down the dentin tubules during mastication. Postoperative hypersensitivity is one of the most frequent complaints in dentistry medicine. A handful of research reports have documented postoperative hypersensitivity with amalgam, tooth-colored, composite resin, luting cements and indirect restoration materials. The present review paper aims at mapping the recent evidence on the incidence of postoperative hypersensitivity with different restorative materials, and further discusses, in the light of latest literature, the prevention tind management of postoperative hypersensitivity.
