Conservative Dentistry - 3 Questions
Acid etching is a dental procedure that creates a micromechanical bond between the tooth surface and a restorative material. This bonding process significantly reduces microleakage, which is the microscopic space between the tooth and the restoration where bacteria and fluids can penetrate.
When punching holes to place a rubber dam for a class V cavity on the facial surface, punching holes larger and facially provides better access and visibility. This allows for easier placement and removal of the dam, as well as less risk of damaging the adjacent tissue
In a Class III cavity preparation, which typically involves the anterior teeth and is located on the proximal surfaces, the axial wall is considered the base. This wall is oriented parallel to the long axis of the tooth and provides support for the restoration. The gingival wall is also important, but the axial wall is the primary base in this context.
