Minimally Invasive Dentistry: The New Paradigm in Dental Care
Minimally invasive procedures are the new paradigm in healthcare. Achieving minimally invasive dentistry follows a philosophy that integrates prevention, remineralization, and intervention. This applies to the placement and replacement of restorations. The goal is to cause the least possible impact on the patient’s mouth.
Minimally invasive dentistry performs treatments using the least invasive surgical approach possible. In other words, it involves removing the minimum amount of healthy tissue. Below, we’ll briefly review the concept of minimally invasive dentistry.
Minimally Invasive Dentistry (MID) aims to preserve tissues—preferably by preventing disease and halting its progression. This means performing treatment with as little tissue loss as possible. For this very reason, it also involves a very precise excision of the area to be removed, without causing any damage to the adjacent tissue.
With new techniques now available—such as low-radiation digital radiography, diagnostic lasers, and the dental surgical microscope— we can aim for both early diagnosis and minimally invasive therapy. Or techniques such as ozone therapy, air abrasion, or the use of rotary instruments for micropreparation and lasers.
The Beginnings of Minimally Invasive Techniques in Dentistry
The principles of dentistry were established in the late 1800s by Dr. G.V. Black, the father of modern dentistry. Among his principles, the concept of “extent for prevention” stands out.
The idea was to eliminate the possibility of caries on the surface of a tooth that was already affected. However, during this restoration, a substantial amount of tooth structure was removed—often several times more than was actually affected. Consequently, many parts of the tooth—including healthy tooth structure—were destroyed in overly invasive procedures.
The minimally invasive approach to treating dental caries incorporates the dental science of detecting, diagnosing, intercepting, and treating dental caries at the microscopic level.
This approach has evolved from a deeper understanding of the caries process, as well as the development of adhesive and biomimetic restorative materials.
With minimally invasive dentistry, dental caries is treated as an infectious disease—not as the end result of one. The radical “extension for prevention” approach is no longer practiced; instead, it has shifted to “constriction with conviction.”
In this way, we can restore problems in the mouth while achieving minimal invasiveness in dentistry.
