Located on the first floor of Arcadia next to Ario, approximately a 9-minute walk from the west exit of Nishiarai Station in Adachi Ward, Tokyo, Nishiarai Otona Kodomo Shika/Kyosei Shika is a dental and orthodontic clinic serving patients of all ages, from children to adults. The clinic's concept is 'protecting teeth for life together with patients and creating teeth they can be proud of,' with four key treatment policies: pain-conscious treatment, minimally invasive treatment that preserves healthy teeth whenever possible, thorough examinations with careful explanations, and customized treatment designed to extend tooth life by 10 years. To address pain concerns, the clinic combines surface anesthesia with electric anesthesia devices to minimize discomfort during injections, creating an environment that accommodates patients who feel anxious about dental treatment. For diagnosis, dental CT and X-rays are used appropriately according to the purpose, and images are displayed on the treatment unit monitor to explain examination results to patients, featuring a highly transparent treatment style. For pediatric dentistry, the director, who belongs to the Japanese Society of Oral Surgery and the Japanese Society of Pediatric Oral Development, adopts an approach that begins with training rather than immediate treatment. The clinic features barrier-free design, allowing strollers into the treatment room, and parents can accompany and observe during treatment. A kids' space is also available, making it an easy environment for families with children to use. The clinic accepts credit cards, debit cards, and electronic payments, and offers Saturday afternoon appointments, making it accessible for those who have difficulty visiting on weekdays.
