An in vivo study evaluating lesion sterilization and tissue repair 3 MIX-MP noninstrumentation endodontic treatment as an alternative to conventional endodontic retreatment

Abstract

Aim: To alleviate the patient's symptoms and promote periapical healing in teeth with failure of root canal treatment, without the removal of previous obturating material using lesion sterilization and tissue repair (LSTR) 3 MIX-MP noninstrumentation endodontic treatment (NIET). Materials and Methods: Fifteen single-rooted teeth with a history of root canal treatment 1–2 years previously, requiring retreatment, with pain, sinus tract, swelling and periapical lesions, and having acceptable obturation were included in the study. The previous coronal restoration was removed, and a medication cavity was prepared for placement of 3MIX MP; this was followed by lining with Glass ionomer cement and a coronal restoration with composite resin. Results: At 8 weeks, all patients did not have either pain, tenderness on vertical percussion, pain on biting, or swelling (asymptomatic). Radiographically, the periapical lesions had reduced by 1 mm in five cases. In six patients, the lesion size remained unchanged. Conclusion: LSTR NIET is an excellent, inexpensive, less traumatic, and least time-consuming alternative to treat symptomatic teeth requiring endodontic retreatment.
