INTRODUCTION:This case report presents that a mandibular molar tooth with large periapical lesion and an old canal filling can be successfully retreated with apical surgery and using Mineral-Trioxide-Aggregate(MTA)
CASE DESCRIPTION:Systemically healthy 35-year-old female patient was referred to our clinic. Intraoral examination revealed that mandibular left first molar tooth had sinus tract. Radiologically, the tooth had an inadequate canal filling and large periapical lesion. Access cavity was prepared under rubber-dam isolation. The apical foramen of the mesial canals could not be reached due to canal transportation from previous endodontic treatment. Working length was determined using periapical radiography and apex locator with reference to the perforation area. After chemomechanical preparation and calcium hydroxide dressing, the cavity was temporarily restored. At the second appointment, the apical 4 mm of the determined working length of the mesial canals was filled with MTA(Bio-MTA, Cerkamed, Poland). The remaining part of the mesial canals and the entire distal canal were filled with the cold lateral condensation technique. After 2 days, apical surgery was performed on mesial root. Permanent restoration was completed with composite resin.
DISCUSSION:The use of a high-quality root canal filling material has a big impact on the surgery's therapeutic outcome(1). Due to its physical and biological properties MTA is one of the materials recommended as root-end filling(2).
CONCLUSION/CLINICAL SIGNIFICANCE:Clinical follow-up at 6 and 10 months showed that the tooth was asymptomatic. Radiographically, periradicular area was completely healed. Apical surgery and the use of MTA provide apical healing for root canals with previous iatrogenic errors such as transportation.
