Objective: Minimally Invasive Dentistry (MID) emphasizes conservative caries management strategies resulting in less destruction of tooth structure. The primary focus in the medical model of caries management is identifying and eliminating the causative factors for caries, along with repairing damage caused by caries. This is a departure from the traditional surgical model because the disease is viewed as an infection rather than as a lesion and its treatment objective is to reduce or eliminate pathogens. The medical model synthesizes knowledge of the disease process into a simple conceptual model using new technologies. Overview: This section should include a brief summary of the findings of the review. Conclusions: The dentist role in MID is recognizing, intercepting and prevention of demineralized sites. Furthermore, assessing the caries risk and maintaining a state of oral health followed by monitoring over extended period of time. Thus, with the philosophy of extension for prevention would lead to extension for ruining teeth. With old challenges at hand to which applying minimally invasive techniques leads to maximum preservation with minimal removal of tooth structure. Technological innovations in materials and techniques gives better results and higher patient acceptance and an easier practice.
