Dentory Co., Ltd. is a company that develops devices and technologies that enable anyone to perform endodontic treatment more easily and quickly using underwater discharge plasma, and conducts research and development on optimized biomaterials.

The PLAZEN Series is an endodontic treatment device utilizing underwater discharge plasma technology. By using a humid environment within the root canal, it is designed to allow endodontic treatment to be performed more easily and quickly, and to reduce stress in endodontic procedures.

A related study was published in the SCI-indexed journal Biomedicines in 2025, and the paper reported experimental results related to the technology.

PLAZEN RCT is the initial model of the PLAZEN Series, and PLAZEN QV is a subsequent model developed based on it, released in April 2026. PLAZEN QV is provided in two configurations: endodontic use and periodontal use.

ANATO-SEAL is an MTA-based bioceramic root canal sealer. It was developed to address the chronic issue of existing products easily setting in air, thereby supporting the continuity of the clinician’s workflow. One of the main features of ANATO-SEAL is that it contains lithium carbonate, and it is designed to act on periapical lesions with expected therapeutic effects, and it has been well received by many clinicians.

Dentory continues to conduct research on dental field technologies utilizing plasma technology and biomaterials.
