Objectives:
To explore correlation between ability of dentists and dental students to recognise the clinical presentation of oral cancer and their self-rated confidence.
Methods:
A cross-sectional, analytical design was used for this study. A validated oral disease recognition scale (ODRS) encompassing a range of benign, premalignant, and malignant oral conditions was used for data collection. For each of the seven patient cases, the participants were asked to provide a diagnosis and rate their self-perceived confidence. Confidence ratings were used as a predictor in a logistic regression model to determine its value as a predictor of diagnosis accuracy, controlling for other factors.
Results:
A total of 252 participants completed the online survey. All correlations between pairs of Cases are positive and statistically significant (p < 0.001). An ordinal logistic regression model predicting Correct vs. Incorrect based on Confidence, Case, participant status, participant gender, and participant age group (and a random effect for participant) suggests that each unit increase in confidence results in a 0.235 unit increase in log-odds of a correct response (an Odds Ratio of 1.265, p < 0.001).
Conclusions:
Overall, confidence ratings appear to predict diagnosis accuracy, after controlling for case and participant characteristics. Notwithstanding the limitations of the current study, the oral disease recognition scale may serve as a useful tool to assess clinicians' ability to recognize oral cancer and identify potential cognitive biases in their clinical assessment skills.
Clinical Relevance:
This study highlights the correlations between diagnostic accuracy and confidence of dentists and dental students in identifying oral cancer, which is crucial for timely referral and improved patient outcomes. By identifying gaps in diagnostic confidence and potential cognitive biases, the findings can inform targeted educational interventions for reliable oral cancer screening in general dental practice.

Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Oral Cavity
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...
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
Assessing Body Temperature - Oral
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...
