Summary
Dental caries removal has evolved from aggressive rotary instruments to less invasive methods like air-abrasion and enzyme techniques. Modern conservative dentistry emphasizes minimal intervention for cavity preparation.
Area of Science:
- Restorative Dentistry
- Dental Materials Science
- Conservative Dentistry
Background:
- Rotary instruments, while fast, cause significant destruction of sound tooth structure.
- Early attempts at less invasive caries removal began in the 1950s.
- Understanding the carious process has driven innovation in dental treatments.
Purpose of the Study:
- To review the historical development of caries removal techniques.
- To analyze the evolution of cavity preparation philosophies.
- To assess methods aimed at minimizing sound tooth substance removal.
Main Methods:
- Historical review of dental instrumentation and techniques.
- Analysis of scientific literature on caries removal and cavity preparation.
- Examination of advancements in conservative dentistry over the last century.
Main Results:
- Various minimally invasive techniques (air-abrasive, ultrasonic, enzyme, chemomechanical, laser) have been developed.
- These techniques have not yet replaced conventional rotary instruments.
- Innovations in cavity preparation include micro-cavity concepts and adhesive dentistry.
Conclusions:
- The field of caries removal and cavity preparation has seen significant evolution towards conservative approaches.
- Minimally invasive techniques and adhesive materials have revolutionized conservative dentistry.
- Further research continues to refine methods for preserving tooth structure during caries treatment.
