Which factor is NOT considered before restoration?

In the context of dental restorations, the factors considered before performing a restoration primarily focus on the health and functionality of the tooth being treated. The elements such as having a good apical seal, no sensitivity to pressure, and no apical sensitivity are critical indicators of the tooth's readiness for restoration.

A good apical seal ensures that there are no gaps that could lead to reinfection or further complications post-treatment. The absence of sensitivity to pressure indicates that the tooth is stable and not inflamed, which is essential for a successful restoration. Additionally, having no apical sensitivity suggests that there is no ongoing pulpal inflammation, making it safe to proceed with the restoration.

Occlusion, while important in overall dental health and function, is not typically evaluated before a specific restoration. The occlusion checks are mainly considered post-restoration to ensure that the new restoration aligns properly with opposing teeth and does not lead to premature wear or discomfort. Therefore, among the factors listed, occlusion is not a direct consideration before the restoration process begins.
