(it vaporizes) A light-cured material does not harden until it has been exposed to a curing light (Fig. False The curing action proceeds from start to finish by itself. Because amalgam and tooth structure do not adhere to each other, a traditional cavity preparation must include a retention form. There are several other factors affecting the dentist's decision-making for material selection such as quantity and quality of the tooth structure, shade of tooth pre and post preparation, position of tooth in the arch, condition of neighboring and opposing dentition, available restorative space, occlusal scheme, malocclusion, patient's . When placed into a prepared tooth, condensed, carved, and allowed to harden, the mixture becomes a permanent amalgam restoration. Retention is the ability to hold two things firmly together when they will not adhere to each other naturally. In press.
