Welcome to the 65th Tri-Service Dental Symposium. This event provides a platform for discussion of present and future challenges as well as innovative ideas in dentistry. Distinguished health practitioners, clinicians, educators will present advanced and practical clinical techniques based upon widely accepted evidence and research. In addition, it provides opportunities to build closer relationships among dental professionals from the three sister service branches and the Japanese Ground Self Defense Force. We look forward to seeing everyone in March 2019.
