Saito Dental Clinic, located in Higashi-Oizumi, Nerima Ward, Tokyo, near Oizumi Gakuen Station, is a historic clinic that has provided community-based dental care for approximately 70 years since its establishment in 1945. Operated by Medical Corporation SmartLeaf, the clinic offers specialized treatment across a wide range of fields including general dentistry, oral surgery, pediatric dentistry, preventive dentistry, cosmetic dentistry, and implants, with a cooperative system with university hospitals and CT centers. A key feature of their practice is the adoption of 'informed consent,' where treatment is proceeded only after patients understand and consent to the treatment plan through careful explanation, and 'informed choice,' which allows patients to select their own treatment method from multiple options, demonstrating a consistent patient-centered approach. The clinic is also designated as a cooperating facility for Nerima Ward's adult dental health examinations and maternal dental health examinations, contributing to local public health. The facility is barrier-free and accepts various payment methods including credit cards, debit cards, and electronic payments. Saturday appointments are available, making it accessible for those who have difficulty visiting on weekdays.
