Minimum Invasive Dental Concept in Endodontics ? From Research and Science to Practice

The minimum invasive dental concept in endodontics was based on 34 years of practical experience in the treatment of more than 10 000 endodontic cases, of the negative trends from the multiple use of resin materials in distal teeth and early metal-ceramic aesthetic crowns and bridges. The scientific dental research includes all aspects of endodontics, which are scientifically and clinically proved with up to date methods and tests clinical exams, anthropometric measurements, epidemiological studies, biochemical tests, light induced fluorescence, different x-ray methods, microbiology, electroodontometric and genetic tests. Experiments with in vitro teeth n= 2201 and clinical research in diagnosis n=8911 teeth and successful treatment of n=3328 teeth in the last 15 years were focused in the preparation of hard dental tissues with most conservative techniques, irrigation, adhesive obturation and restoration methods with amalgam and resins, backup in endodontics in root canals preparation methods and in fixation of posts. A large amount of experience on negative trends and iatrogenic errors after condensation techniques, machine root canal preparations, high concentrations of irrigants and ultra sound methods was carefully analyzed and studied. Therapia magna can be harmful and. machine rotary preparations are very rare good for teeth health. Condensation techniques are not universal. Their indications are much less than single cone ones. Balance of manual forces is a key to success. World is full of dentists, some of them are stomatologysts, but only specialists in dental medicine are able to predict, prevent and to treat iatrogenic errors and to keep in the mouth, as long as possible sound teeth, restored crowns, endodontically treated teeth, roots with posts and cores, or even only natural roots for prosthetic reasons. The conclusions can be focused on basic principles and refocused in the 21 century like The minimum invasive dental concept in endodontics leads to prevention of early extractions, early prosthetic medical procedures, resorptions and to lifetime dental health. This plays a key role in prevention of oral polymetalia, gingival, periodontal and bone changes, metabolic disorders, gastrointestinal diseases.
