Question: 1 / 480

Which of the following factors is critical for successful crown retention?

Type of toothpaste used

Surface area of the tooth preparation

The surface area of the tooth preparation is crucial for successful crown retention because it directly affects the mechanical interlocking and adhesion between the crown and the tooth. A larger surface area allows for better distribution of forces and enhances the grip of the cement or bonding material used to secure the crown in place. This means that the crown is less likely to dislodge or fail over time.

Factors like the type of toothpaste used, frequency of dental visits, and the patient's diet and nutrition may influence overall oral health but do not directly impact the retention of a crown. While oral hygiene is important, the adhesive properties and surface characteristics of the tooth preparation play a more significant role in ensuring that a crown remains securely attached.
