The Versatile Application of Surgical Microscopes in Endodontic Surgery in China

Introduction: In the past, surgical microscopes were primarily used for complex and challenging cases due to their limited availability. However, their utilization in endodontic surgery is essential because it provides better visualization, enables precise and minimally invasive procedures, and can be applied to various surgical steps and cases. In recent years, with the increased prevalence of surgical microscopes in China, their application has become more extensive.

Diagnosis of hidden cracked teeth: Accurate diagnosis of the depth of tooth cracks is crucial for prognosis assessment in clinical cases. Using surgical microscopes in conjunction with staining techniques allows dentists to observe the extension of cracks on the tooth surface, providing valuable information for prognosis assessment and treatment planning.

Conventional root canal treatment: For conventional root canal treatments, surgical microscopes should be used from the initial pulp opening stage. The minimally invasive techniques facilitated by surgical microscopes contribute to the preservation of more coronal tooth structure. Additionally, the clear visualization provided by the microscope aids in the accurate removal of calcifications within the pulp chamber, locating root canals, and performing precise root canal preparation and filling. The utilization of surgical microscopes has led to a three-fold increase in the detection rate of the second mesiobuccal canal (MB2) in maxillary premolars.

Root canal retreatment: Performing root canal retreatment with the assistance of surgical microscopes allows dentists to better identify the causes of failed root canal treatment and address them effectively. It ensures thorough removal of the original filling material within the root canal.

Management of root canal treatment defects: The use of surgical microscopes is invaluable for dentists when confronting challenges such as instrument separation within the root canal. Without the aid of a surgical microscope, removing instruments from the canal would undoubtedly be more difficult and pose greater risks. Furthermore, in cases of perforation occurring in the apex or root canal system, the microscope facilitates accurate determination of the location and size of the perforation.

Conclusion: The application of surgical microscopes in endodontic surgery has become increasingly important and widespread in China. These microscopes offer improved visualization, aid in precise and minimally invasive procedures, and assist in accurate diagnosis and treatment planning. By utilizing surgical microscopes, dentists can enhance the success rates of various endodontic surgeries and ensure optimal outcomes for their patients.
