ABSTRACT:
A thermal tooth tester includes a handpiece which carries circulating water from a heated reservoir through an applicator tip located at the end of the handpiece. The reservoir includes a circulation pump and a temperature control with sensing means to accurately control the temperature of the circulating fluid and, hence, the temperature of the applicator tip. The handpiece further includes a replaceable disposable tip sheath to provide a clean antiseptic surface for each use.
