Root canal calcification is a common and challenging issue in the clinical diagnosis and treatment of dental pulp diseases, closely associated with factors such as age, chronic inflammation, and trauma. This leads to narrowing or obstruction of the root canal, making the procedure more difficult to perform and increasing the risk of complications, thereby reducing the success rate of treatment. Based on clinical practice, this study aims to improve traditional techniques for calcified root canal treatment by addressing limitations such as restricted visibility and rough manipulation. The improvements are made in four dimensions: instrument selection, operational techniques, auxiliary technologies, and process optimization. By refining operational protocols and technical details, the study seeks to reduce the risks of root canal treatment, enhance the success rate, and provide practical references for managing complex calcified root canals, thereby contributing to the overall quality of root canal therapy.
