Title: Assessing the accuracy of provisional diagnosis against histopathology results
Abstract:
Background: Accurate provisional diagnosis is a critical component of effective patient management in oral and maxillofacial practice. Histopathological examination remains the gold standard for definitive diagnosis; however, clinical decision-making often relies initially on provisional assessments. This study aimed to evaluate the proportion of provisional diagnoses that align with final biopsy results and to identify patterns of misdiagnosis. Additional objectives included investigating the influence of clinician experience on diagnostic accuracy, evaluating performance across specific lesion types, assessing correlations between clinical findings and histological outcomes, and identifying opportunities to improve diagnostic processes.
Methods: A retrospective analysis was conducted comparing recorded provisional diagnoses with corresponding histopathological results. This was for a selection of patients over a 3 month period. The exclusion criteria was any patients who did not undergo a biopsy or biopsy of cysts/ jaw pathology. Concordance rates were calculated to determine overall diagnostic accuracy. Subgroup analyses explored variation according to lesion category and clinician experience level. Cases demonstrating results which were not conclusive to a working diagnosis were reviewed to identify recurring diagnostic challenges and potential contributory factors, such as overlapping clinical features or atypical presentations.
Results: The findings demonstrated that a substantial proportion of provisional diagnoses were consistent with histopathological outcomes, reflecting generally strong clinical diagnostic capability. However, discrepancies were observed in specific lesion groups, particularly where inflammatory, reactive, and potentially malignant conditions shared similar clinical appearances. Variability in diagnostic accuracy was noted in relation to clinician experience, suggesting that greater exposure and training may improve alignment between clinical impression and histological confirmation.
Conclusion: The results highlight the inherent complexity of diagnosing oral lesions based solely on clinical presentation. While concordance rates were comparable to those reported in existing literature, opportunities remain to strengthen diagnostic processes. Enhanced clinical documentation, structured diagnostic frameworks, targeted continuing education, and multidisciplinary case discussions may help reduce misdiagnosis rates. Emphasis on biopsy submission for suspicious or ambiguous lesions remains essential to ensure patient safety.
Discussion: In conclusion, although provisional diagnosis demonstrates reasonable reliability, histopathological confirmation remains indispensable. Ongoing evaluation of diagnostic performance and implementation of evidence-based training strategies are recommended to improve clinical-histopathological concordance and optimize patient outcomes in oral healthcare settings.
