Case Study 1: A patient presents with localized swelling mimicking a periodontal abscess on the buccal aspect of tooth #30. Radiographs reveal a radiolucency isolated to the furcation area. Pulp testing shows no response to cold or electric stimulation. A periodontal probe detects a single narrow 8mm defect at the buccal furcation, while all other probing depths around the tooth are 2-3mm. What is the most appropriate diagnosis? A. True combined lesion B. Primary periodontal lesion with secondary endodontic involvement C. Primary endodontic lesion D. Primary periodontal lesion

13. Clinical case A 28-year-old patient presents with a chief complaint of lingering pain in their upper left central incisor after drinking cold liquids. The tooth is restored with a porcelain jacket crown. The clinician applies a cotton pellet saturated with ethyl chloride to the middle third of the crown. The patient reports sharp, severe pain that continues to ache for 20 seconds after the pellet is removed. Based on the provided text, what is the most likely diagnostic conclusion? A) The tooth pulp is healthy and showing a baseline/normal response. B) The tooth is completely non-vital (necrotic). C) The tooth exhibits signs of irreversible pulpitis. D) The test is invalid because cold testing cannot be performed on porcelain jacket crowns.
