TROUBLESHOOTING

The following are some basic troubleshooting procedures for the Midwest Caries I.D.™ detection handpiece that can be performed without the assistance of a qualified technician. For issues not covered in this section, contact DENTSPLY customer service by calling 800-989-8826.

Issue Possible Solution(s)
Failed Calibration Handpiece emits long beep and turns off
  1. Recalibrate the handpiece carefully following the Calibration Procedures in the manual.
  2. Ensure the Probe is fully seated with the Shell and the tip and the ceramic Calibration Target are clean.
  3. If the problem persists, deactivate handpiece and polish the tip of the Probe (refer to the Polish of the Probe section in the Maintenance Procedures) and clean the Fiber Optics (refer to the cleaning the Fiber Optics section).
  4. If the problem still persists, try recalibrating with a new or alternate Probe. If the handpiece calibrates, discard the worn or damaged Probe.
The light at the tip of the probe is either dim or not illuminated.
  1. Ensure the Probe guide notches are aligned properly, fully seated and secure.
  2. Ensure the cleanliness of the tip of the Probe and clean as needed with gauze dampened with isopropyl alcohol. Recalibrate the handpiece (refer to Calibration Procedures section).
  3. If the problem persists, deactivate handpiece, and polish the tip of the Probe (refer to the Polishing of the Probe section in the Maintenance Procedures section) and clean the Fiber Optics (refer to the Cleaning the Fiber Optics section).
  4. Activate the handpiece to determine if the light is sufficient.
The handpiece seems to be giving false or incoherent detection signals or beeping inconsistently.
  1. Ensure the cleanliness of the tip of the Probe and clean as needed with gauze dampened with isopropyl alcohol. Recalibrate the handpiece (refer to Calibration Procedures section).
  2. If the problem persists, deactivate handpiece, and polish the tip of the Probe (refer to the Polishing of the Probe section in the Maintenance Procedures section) and clean the Fiber Optics (refer to the Cleaning the Fiber Optics section).
  3. Using the air syringe, dust the holes at the top of the battery shelter (where the LED lights are), to remove any debris that may obstruct the Fiber Optics.
  4. Connect the Probe and calibrate the handpiece.
  5. Tilt overhead light toward patient's chin, away from the oral cavity.
  6. Follow normal methods to remove heavy plaque and calculus from teeth.
The detection handpiece beeps when outside the mouth.
  1. Ensure the cleanliness of the tip of the Probe and clean as needed with gauze dampened with isopropyl alcohol.
  2. If the problem persists, deactivate handpiece, and polish the tip of the Probe (refer to the Polishing of the Probe section in the Maintenance Procedures section) and clean the Fiber Optics (refer to the Cleaning the Fiber Optics section).
  3. The Midwest Caries I.D. TM detection handpiece is calibrated for intra-oral use (moist environment). Certain amounts of ambient luminous reflections ca partially imitate the optical signature of the caries and may result in a detection signal.
The detection handpiece emits a detection signal on contact or near a dental restoration or sealant
  1. Some restorations reflect the general view and optical signature of the detection beam and could imitate the optical signature of the caries. The handpiece is not to be used on or near dental restorations
The LED light seems to be fading and/or the handpiece does not seem to be detecting any caries.
  1. Deactivate the handpiece and remove the Probe.
  2. Using the air syringe, dust the holes at the top of the battery shelter (where the LED lights are) to remove any debris that may obstruct the fiber optics.
  3. Connect the Probe and recalibrate the handpiece.
The red LED lights up but no beep is heard.
  1. Adjust the volume by pressing on the On/Off button until it is loud enough.
  2. Install fresh batteries.
No audible or visual signals.
  1. Do not use detection handpiece. Contact DENTSPLY Professional Technical Service and Repair Department at 1-800-989-8826.
