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).
