Abstract
A method of and device for testing for conditions, particularly moisture conditions, in root canals and for drying the root canal. In accordance with the method, a small pointed implement in the nature of a rolled piece of paper having pH indicator on the tip thereof is inserted into the root canal. The pH indictor, by change of color, will present information as to whether or not any moisture is present in the canal and, secondly, whether or not the moisture is a positive pH or negative pH.
Claims15
A method for detecting whether moisture is present in a root canal of a tooth, said method comprising:
- a) inserting an implement containing a color change indicator which changes color in response to presence of moisture into the root canal of a tooth;
- and
- b) withdrawing the implement from the canal of the tooth and determining whether the indicator has changed color which thereby provides indication of the presence of moisture.
An implement for determining whether or not moisture is present in a root canal of a tooth and whether that moisture may cause a color change to show presence of moisture, said device comprising:
- a) an elongate rod like member having an enlarged upper end for engagement by the fingers of a user;
- b) a tip at the lower end of said rod like member and having a cross-sectional size such that it will fit into a root canal of a tooth;
- and
- c) a color change indicator on said rod like member adjacent the lower end thereof for indicating the presence of moisture in a root canal of a tooth by a color change when the implement in inserted in a root canal and shows a change of color.
An implement for determining whether or not moisture is present in a root canal of a tooth and whether that moisture may have a certain pH associated therewith, said device comprising:
- a) an elongate rod like member having an enlarged upper end for engagement by the fingers of a user;
- b) a tip at the lower end of said rod like member and having a cross-sectional size such that it will fit into a root canal of a tooth;
- and
- c) a section of the lower end of said rod like member adjacent the tip which is capable of being inserted into a root canal of a tooth and which lower end is responsive to the presence of moisture and will change color in the presence of moisture and thereby indicates to a user the presence of moisture in a root canal of a tooth when the implement in inserted therein.
