竹内佐年 Dental Office is a dental clinic located in Nishikimachi, Toyota City, Aichi Prefecture. The clinic takes thorough measures to prevent hospital-acquired infections, using disposable gloves, aprons, and cups. For instruments that cannot be disposed of, they use a "washer-disinfector"—state-of-the-art equipment capable of cleaning even the finest details—before sterilization. The clinic also focuses on water hygiene management, having implemented a "Poseidon" system that circulates sterilized water within treatment units to keep treatment water clean. The facility is barrier-free equipped with a parking lot. Payment options include credit cards and electronic payments, and English support is available. Closed days are Thursdays, Sundays, and public holidays. However, if a public holiday falls within a week, Thursday appointments are available. The clinic is closed from December 29 to January 4 for year-end holidays, and from August 13 to 15 for Obon.
