Non-Surgical Re-Treatment Case II: Maxillary Premolar

This chapter presents a case of the patient (Pt) who was a 34-year-old male. He had no relevant medical history and was not taking any medications at the time of visit. His vital signs were as follows: blood pressure (BP) 132/87 mmHg; pulse 78 beats per minute (BPM) and regular. A complete review of systems did not reveal any significant findings and there were no contraindications to treatment. The Pt was American Society of Anesthesiologists Physical Status Scale (ASA) Class I. The Pt experienced dull pain around his right upper posteriors. The case presented in the chapter helps dentists to understand the difference between root canal re-treatment and initial treatment. It also helps them to understand the clinical success rate for re-treatment, and the methods and techniques of root canal re-treatment.
