Koide Dental Clinic, located in Kita-Fukashi, Matsumoto City, Nagano Prefecture, prioritizes the preservation of natural teeth and provides dental care based on MI (Minimally Invasive) treatment, which removes only the minimally necessary portion of decayed teeth. The clinic has introduced advanced equipment such as dental microscopes, 3D CT, implant systems, and the optical scanner "iTero," offering precise treatments aimed at preserving healthy tooth structure. In root canal treatment, the clinic performs world-standard treatment using specialized instruments like NiTi files and rotary motors, prioritizing the preservation of dental pulp. In clinical practice, the clinic utilizes microscopes to implement precise dental treatment that removes only the necessary areas more accurately, and uses a recording system to clearly explain treatment content and oral conditions through photos and videos. The clinic also focuses on preventive dental care, quantifying the presence and progression of hard-to-see cavities with laser detectors, and providing custom preventive dentistry tailored to each patient's oral condition. The clinic offers convenience with English-speaking staff and on-site parking.
