The most likely cause(s)of sensitivity following placement of composite restorations is(are):

Question

Quizplus · Accepted Answer

Sensitivity following placement of composite restorations is most commonly caused by induced internal stress and microleakage of bacteria. Internal stress can occur due to polymerization shrinkage or variability in the coefficient of thermal expansion between the composite restoration and tooth structure. Microleakage of bacteria can lead to pulpal inflammation and subsequent sensitivity. Occlusal interference and the use of acid etchant are less common causes of sensitivity following composite restoration placement.
