    摘要： To provide a method for manufacturing an interdental cleaning tool that can prevent deformation of a core base at molding of a cleaning flexible part using an elastomer material, thereby effectively preventing occurrence of molding failure of the cleaning flexible part.
    The method in the present invention includes: a base part molding step of providing first metal molds 30 and 31 for molding base parts with a plurality of first molding spaces 32 aligned in parallel and including core base molding sections 32a and handle base molding sections 32b, providing the first metal molds 30 and 31 with connection part molding sections 35 to communicate with the adjacent handle base molding sections 32b, and supplying a synthetic resin material with a fiber material at a time to the plurality of first molding spaces 32 from gates 34 to form a plurality of base parts at a time; and a flexible part molding step of setting the core bases of the base parts into second metal molds, holding the core bases at two or more longitudinal portions by a plurality of pairs of hold pins in the second metal molds, each pair including two pins, and charging an elastomer material into the cleaning flexible part molding spaces.

    摘要： The present disclosure provides a computer implemented method for automatic detection of teeth clenching and/or teeth grinding in a dataset representing the level of biting force vs. time of a subject, the method comprising the steps of a) calculating a threshold level of biting force assigned to time t=t1 based on a background level determined from the dataset at a prior time t=t1−Tback, where Ttrack is a first predefined period of time, b) checking the level of biting, and if the level of biting force at time, t, exceeds the threshold level assigned to time t for a second predefined period of time, Tclench/grind, then assigning an event of teeth clenching to time t, c) if an event of teeth clenching has been assigned to time t, then either waiting a predefined period of time 10 Twait, or waiting until the level of biting is below the threshold for another predefined period of time Tend, d) if no events of teeth clenching and/or teeth grinding have been assigned for a third predefined period of time Tsilence, then repeating steps a)-c), e) if events of teeth clenching and/or teeth grinding have been assigned for a third predefined period of time Tsilence, then repeating only steps b)-c).

    摘要： A palpometer device for assisting an examiner to evaluate deep pain sensitivity in a patient includes a housing supporting an axially displaceable spring-biased probe having a proximal end extending from an axial bore in a proximal axial face of the housing, and adapted for abutting contact with the patient. Within the housing, the spring-biased probe incorporates an annular flange for engaging one end of a bias spring coaxially disposed within the housing. The bias spring is disposed coaxially about the probe to resist axial displacement of the housing towards the proximal end of the probe upon manual application of a bias force to the housing, when the proximal end of the probe is in contact with a patient's body.
