Question

Quizplus · Accepted Answer

An occlusal interference and the use of acid etchant during placement are the most likely causes of sensitivity following placement of composite restorations. An occlusal interference can cause trauma to the tooth and surrounding tissues, resulting in sensitivity. Acid etchant can cause demineralization of tooth structure, leading to pulp irritation and sensitivity. Microleakage of bacteria and induced internal stress are less likely to cause sensitivity immediately following placement of the restoration.
