Located in Showa-ku, Nagoya City, Aichi Prefecture, Maruyama Dental Clinic is a dental clinic equipped with a parking lot and barrier-free facilities. The clinic is closed on Sundays, Thursdays, and public holidays. In addition to oral hygiene management, treatments incorporate rehabilitation techniques to balance and restore bodily functions. Poor posture, such as a hunched back or rounded shoulders, can place excessive stress on teeth through positional changes, potentially leading to tooth sensitivity and cavities. In severe cases, it may cause pain in the tissues supporting the teeth and impair temporomandibular joint function and swallowing ability. For infection control, the clinic implements sterilization of instruments and uses extraoral suction devices to capture aerosols during treatment. The waiting room and treatment rooms are kept with doors open for ventilation, and the entire building is ventilated by a forced-air system. The waiting room utilizes hypochlorous acid for air disinfection to suppress viral activity. Pre-treatment screenings are conducted, and patients with symptoms such as cough, sore throat, difficulty breathing, severe fatigue, or fever of 37.5°C or higher, as well as those who have had contact with such individuals within 14 days, are advised to postpone their appointments. The clinic uses disposable supplies, along with masks, goggles, and face shields, and employs a mouthwash containing benzalkonium chloride.
