He also complained that he believes the infection is spreading to his cheek and it has also become very painful. Upon taking a history, the patient informed you that he has been placing aspirin powder directly on the tooth as the pain was too severe. A clinical examination reveals a deep carious lesion on the 36. The intra-oral examination also revealed a white lesion in the buccal sulcus adjacent to the 36. Special investigations in the form of a periapical radiograph revealed a carious lesion extending into the dental pulp of the 36. How would you comprehensively manage this patient?
