The FDA and ADA have issued public advisories stating that dental handpieces can overheat during use, to the point of causing soft tissue burns if the instrument in question is not cleaned, lubricated, and maintained according to the manufacturer's instructions. IMPORTANT: It is the responsibility of the user to carefully follow the instructions provided herein as regards to proper care and maintenance of dental handpieces and electric motors. It is further suggested that each user should maintain a written log for each dental handpiece or motor in service, recording the service and maintenance care given to the corresponding instrument, and dates. Failure to perform adequate service of these instruments does, in the event of tissue damage, shift the liability for same to the user. The manufacturer is not responsible for any harm or damage done by an instrument that is not properly serviced and maintained.
