Koizumi Dental Clinic, located in Hoshioki, Teine-ku, Sapporo, is a dental clinic that provides precise dental treatment centered around dental microscopes. The clinic is staffed with a certified dentist from the Japanese Academy of Microscopic Dentistry and a specialist from the Japanese Endodontic Association, allowing for accurate diagnosis and treatment even in hard-to-see areas such as the interior of tooth roots and deep within the gums. The microscope is utilized across a wide range of treatments, including not only root canal therapy and cavity treatment but also general dental care, enabling high-precision procedures that minimize unnecessary removal of tooth structure and reduce the risk of oversight and retreatment. During precise treatments, the clinic uses the rare Morita Space-line Feel 21 Type N full-flat dental chair in Japan, allowing patients to receive treatment in a completely reclined position from the start, which reduces physical strain during long procedures. The clinic offers a comprehensive range of dental services, including preventive dentistry, cavity treatment, endodontic therapy (root canal), periodontal treatment, pediatric dentistry, denture treatment, orthodontics, occlusal treatment, and aesthetic dentistry, addressing various dental needs. English-speaking services are available, and the clinic provides on-site parking. Appointments are available primarily on weekday mornings (9:00-13:00) and Saturday mornings, with afternoon hours (14:30-17:30) on weekdays. The clinic is closed on Wednesdays, Sundays, and holidays.
