Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Summary

Visible and near-infrared optical methods for early caries detection showed limited diagnostic value for assessing lesion depth in teledentistry. Simple visual photographic assessment (CAM) performed comparably to advanced devices.

Area of Science:

  • Dental diagnostics
  • Optical imaging technologies
  • Preventive dentistry

Background:

  • Optical caries detection offers potential for teledentistry in preventive dental screening.
  • Early detection of non-cavitated occlusal demineralization is crucial for timely intervention.

Purpose of the Study:

  • To evaluate and compare visible and near-infrared optical detection methods for early non-cavitated occlusal demineralization.
  • To assess the diagnostic accuracy and reliability of different caries detection devices.

Main Methods:

  • Three diagnostic methods were compared: Midwest Caries ID (MID), visual photographic examination (CAM), and Cross Polarization Optical Coherence Tomography (CP-OCT).
  • Six blinded examiners assessed extracted teeth, with lesion depth confirmed histologically.
  • Sensitivity, specificity, Intraclass Correlation Coefficient (ICC), and Area Under the Curve (AUC) were calculated.

Main Results:

  • CAM and CP-OCT showed higher sensitivity for detecting any demineralization than MID, but lower specificity.
  • None of the methods accurately assessed the depth of non-cavitated lesions into dentin.
  • MID exhibited the highest reliability (ICC=0.83), while CP-OCT had the lowest (ICC=0.49).

Conclusions:

  • MID and CP-OCT detected demineralization presence but failed to adequately assess lesion depth.
  • These advanced optical methods did not demonstrate significantly superior diagnostic value compared to simple CAM assessment for teledentistry applications.
  • Further research is needed to improve optical methods for accurate caries depth assessment in remote screening.
