Located in Chuo Ward, Sapporo, Hokkaido, Hokkaido Oral Pathology Laboratory is Japan's first dental clinic specializing in oral pathology and oral cytology. Pathology diagnosis is a specialized examination that accurately determines the nature and extent of lesions by examining tissues and cells taken from the oral cavity under a microscope. This results directly leads to the selection of appropriate treatment strategies. As a facility focused exclusively on this field, the clinic plays a role in improving diagnostic accuracy in dentistry. Even for cases where understanding the disease condition is difficult with general dental treatment alone, such as periodontal disease, oral mucosal diseases, and oral tumors, the clinic can provide more accurate information through pathological and cytological diagnosis. Through this high-level diagnostic system, it contributes to improving the safety and reliability of dental healthcare. Additionally, as English services are available, the facility offers an accessible environment for patients who require communication in languages other than Japanese. The clinic is closed on Wednesdays and Sundays. It plays a unique specialized role in Hokkaido as a facility providing diagnostic services for patients who need accurate diagnosis of oral diseases and responding to requests from other dental and medical institutions.
