1.1 Cоmpаre tоrus mаndibulаris and оsteoma with reference to five (5) clinical and radiological features. (5)1.2 A 27-year-old woman is referred for assessment of an incidental radiopaque lesion in the mandibular premolar–molar region, identified during routine panoramic radiography. The adjacent teeth are vital, caries-free and asymptomatic. Clinical examination reveals no swelling, tenderness or cortical expansion. The radiograph shows a homogeneous radiopaque focus within the mandibular trabecular bone, with well-defined margins. The lesion is not fused to the roots, and the periodontal ligament spaces and lamina dura of the adjacent teeth are preserved.a) State the most likely diagnosis. (1)b) List two (2) important differential diagnoses for this localised radiopaque lesion. (2)c) For each differential diagnosis identified in Question (c), state one (1) clinical or radiological features that would help distinguish it from the suspected diagnosis. (2)d) Recommend three(2) clinical or radiographic assessments that would help confirm the working diagnosis and exclude relevant alternatives. (3)e) Describe the appropriate management of the lesion in this patient. (2)
