Summary
Smart Root Canal Therapy (RCT) integrates digital intelligence and advanced technologies to enhance precision, safety, and biological outcomes in endodontic treatments. This review explores the evolution and application of these smart innovations in modern dental care.
Area of Science:
- Endodontics
- Dental Technology
- Biomaterials
Background:
- Root canal therapy (RCT) is the standard treatment for pulpal and periapical diseases.
- Technological advancements have continuously refined RCT procedures over the past century.
- Evolving diagnostic tools, instrumentation, disinfection, and obturation materials aim to improve treatment efficacy.
Purpose of the Study:
- To systematically review the development and application of 'Smart RCT' technologies.
- To provide an evidence-based perspective on integrating intelligent advances into endodontic practice.
- To critically evaluate the potential and limitations of smart technologies in RCT.
Main Methods:
- Systematic synthesis of contemporary evidence on smart technologies in RCT.
- Review covers diagnostic, treatment, disinfection, and obturation stages.
- Critical evaluation of existing research and clinical applications.
Main Results:
- Diagnostic approaches have advanced from 2D imaging to AI-assisted 3D analysis.
- Treatment modalities have progressed to motor-driven, guided, and robotic systems.
- Disinfection is shifting to active, nano-enabled systems, and obturation materials are becoming bioactive.
Conclusions:
- Smart RCT integrates digital intelligence, engineering assistance, and material science for improved endodontic outcomes.
- These technologies enhance precision, safety, and efficiency in RCT.
- The primary goal of RCT remains infection elimination and prevention, now supported by intelligent advancements.
