Later, three different blinded examiners (licensed dentists) will assess the intraoral photographs of the same group of participants. The participant's dentition will be examined using the scores developed by the World Health Organization (WHO) for oral health surveys. Also, the examiners will perform a visual inspection of the oral mucosa for any signs of oral potentially malignant disorders (OPMD), as the mortality of high-risk populations is proven to be reduced by visual oral cancer screening.

Finally, the residents who require treatment will be referred to Kasr EL Ainy dental hospital to receive dental treatments.

The participant's dentition will be examined using the scores developed by the World Health Organization (WHO) for oral health surveys. Also, the examiners will perform a visual inspection of the oral mucosa for any signs of oral potentially malignant disorders (OPMD), as the mortality of high-risk populations is proven to be reduced by visual oral cancer screening.
