A case report on Nonsurgical Retreatment and Iatrogenic Perforation Repair Using Mineral Trioxide Aggregate | Chapter 18 | Issues and Developments in Medicine and Medical Research Vol. 9

 The most common causes of root canal failure are micro leakage and bacterial infection. Endodontic treatment failure is frequently determined by the development of fresh or persistent periapical radiolucency close to a root-filled tooth. Incomplete obturation, insufficient coronal seal, missing canals, iatrogenic events like as tool separation, and lateral perforations are the most prevalent causes of endodontic failure. The second leading cause of treatment failures is perforations during endodontic operations. Accessibility and visibility, duration and size of perforation, periodontal status, and the quality of root canal treatment, the strategic importance of the tooth, the patient's oral hygiene, and the operator's experience are all factors that must be considered when treating these perforations surgically or non-surgically.

 

Presentation of a Case: A 32-year-old female patient presented to the clinic with a discoloured front tooth that caused slight pain when chewing or biting. The patient stated that he had been in a car accident five years prior and that he had had root canal treatment three years prior. The standard rubber dam isolation approach was followed. The entrance to the coronary artery was fine-tuned and cleansed.

 

The goal of this case report is to present an endodontic retreatment and nonsurgical treatment of a significant periapical radiolucency in a maxillary central incisor with coronal third perforation that was effectively treated with MTA-Angelus without matrix. In the anterior teeth, aesthetic was restored using all-ceramic crowns.

Conclusion: There were no evidence of infection at the six-month, one-year, and two-year follow-up sessions, and the tooth remained asymptomatic. The radiograph revealed indications of osseous healing, including periapical radiolucency resolution, periradicular tissue repair, and cementum deposition over MTA at the perforation site. Despite a poor prognosis, the current case report revealed positive clinical outcomes, indicating that the method is promising.
