Internal wall is a prepared ( cut ) surface the extend to the external tooth surface. Axial wall is an internal wall perpendicular to the long axis of the tooth

Preparation two surfaces called compound. Preparation involving only three surfaces called complex

Caries of pit and fissure forms a small area of penetration in the enamel at the bottom of a pit or fissure and spread laterally. Root surface caries most commonly on elderly patients with gum recession

Root surface caries most susceptible site of caries. Caries of enamel less favorable site for plaque attachment

Class IV caries in the proximal surface of anterior teeth also involving the incisal angle. Class III caries in the proximal surface of anterior teeth and not involving the incisal angles

Lesion on unrestored surfaces called recurrent caries. Lesions developing adjacent to fillings called secondary caries
