Point Angle: The sharp junction where two walls meet within the cavity, playing a significant role in the structural integrity and shape of the preparation.
Line Angle: Formed at the intersection of two walls, line angles are essential in defining the cavity geometry and aiding in the placement of restorative materials.
Cavo Surface Angle: The angle between the external surface of the tooth and the cavity wall, important for optimizing the seal and reducing the risk of microleakage.
