Conservative DentistryExplanation: The outline form of a Class V cavity preparation is primarily determined by the extent of carious tissue. The goal is to remove all carious dentin while preserving as much healthy tooth structure as possible. The outline form must encompass the entire area affected by caries to ensure that the restoration is effective and durable. Other factors, such as the height of the gingival crest, type of restorative material, and tooth anatomy, may influence the preparation but are secondary to the extent of caries.
