Evaluation of Diagnostic process in Oral Surgery Department A cross-sectional Study for 5th Year Dental Students at Mustansiriya University


Introduction: Diagnosis is one of the important skills for dental students. During their clinical training dentalstudents make diagnostic mistakes, which are expected because of limited knowledge and experience. Despitethe fact that these diagnostic problems are usually addressed during the clinical training in the final two years,the exact reasons for diagnostic inaccuracies made by students have not been investigated thoroughly in Iraqidental schools.Aim: The aim of the study is to identify factors influencing the appropriateness of diagnostic procedure by studentsperforming dental extraction.Material and methods: Eight Selected items from the case sheet of the Department of Oral Surgery were usedto evaluate the student’s accuracy of surgical diagnosis. Seventy eight dental students were included in the study.After completion of surgical (dental extraction) procedure, each student was asked about the reason behind thediagnosis.Results: Documentation of selected items reported as follows: chief Complaint (CC) field was neglected in 9%;history of present illness has been neglected in 73 case sheets (93.6%). Chi square test, however, showed nosignificant relationship between history taking (CC and HPI) and the accuracy of diagnosis. Extraoral clinicalexamination included lymph node (LN) examination, which was reported in 42 cases (53.8%); and facial swelling,which has been reported in 45 (57.7) cases. Intra oral examination items reported as follows: cavity probingwas documented in 33 (42.3%) cases; tooth percussion for tenderness documented in 50 (64.1%) cases;examination for tooth supporting structure reported in 46 (59%) cases. Chi Square Test did not show significantrelationship between both extra and intra oral examination and the accuracy of diagnosis (p>0.05, df=12). 56students, however, made their diagnosis by guess rather than accurate diagnosis process. How about the differencesyou observed by gender?Conclusion: There is an obvious lack of documentation in both history taking and clinical examination. This mightnegatively influence proper diagnostic procedure.
