Assessment of the Mouth01:26

Assessment of the Mouth

1.1K
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

1.5K
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...

Equipments Used To Measure Blood Pressure

3.1K
Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Area of Science:

  • Biomedical Engineering
  • Dental Science
  • Biomechanics

Background:

  • Occlusion and dental arch form are linked to oral soft tissue morphology and function.
  • Dynamic assessment of oral soft tissues is crucial for understanding malocclusion.
  • Previous development of a mouthguard-type sensor for oral soft tissue pressure required further evaluation of continuous measurement capabilities.

Purpose of the Study:

  • To evaluate the continuous measurement performance of a novel mouthguard-type sensing device.
  • To assess the device's ability to measure tongue pressure on the palate during swallowing.
  • To investigate the relationship between oral soft tissue dynamics and dental occlusion.

Main Methods:

  • A mouthguard-type device integrating a pressure sensor, wireless communicator, and battery was utilized.
  • Tongue pressure on the palatal surface of the maxillary anterior teeth was measured during 10 consecutive 10 mL water swallows in a single participant.
  • Data analysis focused on identifying pressure spikes corresponding to individual swallowing events.

Main Results:

  • The device clearly distinguished each swallowing event through identifiable pressure spikes.
  • The mean tongue pressure per swallow was recorded as 181.97 ± 31.84 g/cm², with a range from 137.72 to 224.97 g/cm².
  • Measured tongue pressure values were consistent with previously reported data for swallowing.

Conclusions:

  • The developed mouthguard-type (MG) pressure-sensing device demonstrated successful continuous measurement of tongue pressure in a single subject.
  • Further research with larger sample sizes is needed to comprehensively assess the device's long-term monitoring capabilities for dynamic oral soft tissue pressure.
  • This technology holds potential for advancing the study of malocclusion etiology and treatment strategies.
