As the field of dentistry advances and the use of technology in the field increases, the concept of minimally invasive dentistry has emerged. Preservation of a healthy set of natural teeth for each patient should be the objective of every dentist. Minimally invasive dentistry is characterized by the following core beliefs:

• Regard original tissue as more valuable than its artificial counterpart.
• Preserve, rather than replace, original tissue
• Focus on the prevention of disease above its treatment.
• When treatment is necessary, use invasive means as little as possible.

Prevention
Prevention begins with good oral hygiene.Dental caries are considered an infectious disease.Early detection of caries and other diseases can prevent the spread of infection and, consequently, further damage to healthy tissue.Infection control can reduce the incidence of restoration practices by as much as 50 percent.Focus on remineralization of enamel and dentin as a preventive effort in treating caries.
