Abstract : 

Minimal Intervention Dentistry (MID) is a philosophy or concept that attempts to ensure that teeth remain functional for life. Its development was facilitated by the numerous studies carried out on topics related to cariology that were carried out since 1940, including sugar consumption, oral microbiota, fluorides, adhesive dental materials and the so-called repeated restoration cycle. By the early 1990s, research had shown that the management of dental caries lesions could be better accomplished, moving away from the traditional surgical approach in favor of a 'biological' or 'medical' approach. This approach encompasses the following important strategies that aim to keep teeth free from caries lesions: (i) early detection of lesions and assessment of caries risk with validated instruments; (ii) remineralization of demineralized enamel and dentin; (iii) optimal caries prevention measures; (iv) tailor-made controls based on risk; (v) minimally invasive operative interventions; and (vi) repair rather than replacement of restorations. 

Learning objectives : 

• Recognize the principles of contemporary cariology recommended for the management of dental caries
• Analyze the efficacy and feasibility of non-restorative approaches postponing the first operative intervention
• Review the evidence behind strategies to control the progression of enamel and dentin lesions through no invasive, micro-invasive and minimally invasive approaches
