Which of the following statements regarding enamel beveling for composite restorations is incorrect?

The statement that bevels are placed on cementum areas too is considered incorrect. In the context of composite restorations, enamel beveling is primarily performed on enamel surfaces to enhance the esthetic blending of the restoration and to increase the adhesive capabilities of the composite material.

Beveling the enamel provides more surface area for bonding and helps the margins of the restoration to be less visible, thereby creating a more seamless transition between the natural tooth structure and the composite. This technique is especially relevant in anterior teeth, where aesthetics are paramount. However, when it comes to cementum, the use of bevels is not standard practice. Cementum is of a different composition and does not respond to bonding in the same way as enamel; typically, it is not beveled during procedures since it can lead to weaker adhesion and potential sensitivity issues.

Understanding the role and importance of beveling in the context of esthetics and adhesion helps clarify why this statement is incorrect. Other statements accurately reflect the principles of beveling techniques in relation to aesthetics and the areas where they are effectively applied.
