Dental students' ability to detect and diagnose oral mucosal lesions.

The aim of this study was to assess the ability of dental students in the screening clinic of the Kuwait University Dental Center to detect and diagnose oral mucosal lesions. Clinical examinations performed by dental students between January 2009 and February 2011 were included. All their findings regarding the oral mucosal lesions and dental carious lesions detected were recorded, after which the patients were re-examined by faculty examiners. The students rated their own ability to detect mucosal and carious lesions before each examination. Among the 341 patients screened, 375 oral mucosal lesions were found by the faculty examiners. Of those, the students detected 178 (47.5%). Out of the 375 lesions, including the ones they failed to detect, the students diagnosed 272 (72.5%) correctly. The students were more likely (p≤0.01) to correctly diagnose a mucosal lesion when they themselves had detected it (n=169/178) than when they failed to detect it and had it subsequently pointed out by the faculty examiners (n=103/197). The students were more competent in detecting carious lesions (p≤0.001) than in detecting mucosal lesions. A significantly higher proportion of students who felt confident in detecting mucosal lesions were actually more competent in detecting the lesions than those who were not confident (p≤0.001). Further educational strategies are needed to motivate Kuwait University dental students to develop the knowledge, skills, and judgment necessary to integrate a complete intraoral examination into their routine practice.
