Assessment of the Mouth01:26

Assessment of the Mouth

1.5K
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.

Cancer Prevention02:59

Cancer Prevention

8.7K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Cancer

55.8K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Oral Cavity01:11

Oral Cavity

3.9K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Area of Science:

  • Oral health
  • Public health
  • Cancer prevention

Background:

  • Oral cancer screening is crucial for early detection and reducing mortality.
  • Dental hygienists play a key role in patient education and screening.
  • Understanding practice gaps and barriers is essential for improving oral cancer detection rates.

Purpose of the Study:

  • To assess the translation of oral cancer screening knowledge into practice among dental hygienists.
  • To identify barriers hindering the performance of comprehensive oral cancer screenings by dental hygienists.

Main Methods:

  • A cross-sectional study utilizing a 27-item survey distributed to licensed dental hygienists in Nova Scotia.
  • Data analysis included descriptive statistics and qualitative thematic analysis of open-ended responses.
  • A response rate of 34% (n=212) was achieved, with a maximum margin of error of 5.47% at a 95% confidence level.

Main Results:

  • A significant gap exists between dental hygienists' perceived knowledge and actual practice of oral cancer screening.
  • Only 13% of respondents performed comprehensive extra-oral examinations, and 7% performed comprehensive intra-oral examinations.
  • Respondents reported multiple barriers preventing the completion of thorough oral cancer screenings.

Conclusions:

  • There is a professional imperative for dental hygienists to perform comprehensive oral cancer screenings for early detection.
  • Barriers to screening may require practice-level or systemic interventions, potentially beyond the hygienist's direct control.
  • Increased public awareness of oral cancer screenings can drive demand and influence practice norms, improving detection rates.
