Case history/examination
A 28-year-old man with no history of systemic disease, allergies, or regular medication use was referred to the endodontic department for the treatment of a maxillary second premolar. The patient reported experiencing occasional pain in the upper left posterior region, describing it as moderate and intermittent. No facial swelling or lymphadenopathy was observed during the extraoral examination. The intraoral examination showed severe cold hypersensitivity, indicating pulp irritation. The response from the electric pulp testing procedure confirmed that the vitality of the pulp remains intact while also indicating an increased level of sensitivity in the affected tooth. percussion and palpation tests were normal with no periapical or periodontal issues. The patient was diagnosed with symptomatic irreversible pulpitis and required immediate endodontic treatment to address the inflammation and maintain periapical tissue health. The pericapical radiograph revealed extensive disto-occlusal caries and PDL widening without radiolucency (Figure 1. A). Also, the first and second curvatures of the tooth were calculated at 40° and 72°respectively by the Southard approach in radiograph (Figure1. E)(7).
