Introduction

    In Division of Endodontics, we mainly treat teeth that have pulp diseases. Generally speaking, endodontic treatment can be classified as conventional and surgical root canal therapy. Most of the pulpal and periapical diseases can be treated by conventional root canal therapy. In some cases for which conventional treatment cannot cure the disease, or when there is larger osseous lesion in the periapical region, surgical endodontic treatment is considered as an alternative choice by removal of a portion of root apex and retrofilling of the root canal by biocompatible materials during apical surgery.

Device for therapy

Device for micro-surgery：Under the magnification, identifying the canals orifice, removing separated instruments, and repairing perforation become much more easily than before. Operative microscope combined with endodontic surgery result in decreasing tissue damage and improving wound healing. It markedly improves the Endodontic treatment outcome.

Ultrasonic instruments: In endodontic field, the ultrasonic instrument can be used to remove posts, old root canal filling materials, and separated instruments by its special vibrating motion. In endodontic surgery, ultrasonic instruments with special designed tips can make every step precisely done. Because the size of ultrasonic tip for microsurgery is designed to be much smaller, destruction of the healthy root structures can be minimized. This can promote wound healing after apical surgery and decrease postoperative discomfort.

Rotary Ni-Ti instruments: The advantages of flexible Ni-Ti rotary instruments are the motor with constant RPM combined with super-elastic and shape memory properties of NiTi alloy. It can cut efficiently, follow the original shape and curvature of root canal, as well as remove the infected tissue and tooth substances. Ni-Ti rotary instruments make root canal therapy rapidly and efficiently.

Thermoplastic obturation equipment: After thorough cleaning, dense root canal obturation is one of the keys to successful treatment. In addition to the traditional lateral compaction equipment, Division of Endodontics introduced thermoplastic obturation equipment. In some teeth with irregular root canal system, such as external root resorption, internal root resorption etc, the root canal system can be adequately obturated by thermoplastic obturation. technique. Therefore, it would be a tremendous choice.
