Follow-up:Different Root Canal Filling of Necrotic Internal Resorption Teeth

The aim of this study was to demonstrate the successful treatment of two lateral incisors with internal resorption using two different bioceramic materials under the operating microscope.

A 22-year-old female patient presented to Erciyes University, Faculty of Dentistry,Department of Endodontics for routine examination.As a result of radiologic and clinical examination, internal resorption was observed in the middle triad region of teeth12 and 22 and lesions were observed in the apical region. Teeth 12 and 22 responded negatively to thermal tests. There was no pain on percussion and palpation and the teeth were asymptomatic.In the first session, the teeth were isolated with rubberdam and access cavities were opened under the operating microscope. The root canals were prepared using Reciproc #25and#40(VDW,DentsplySirona,Munich) rotary files. Irrigation was carefully performed using 2.5%NaOCl.The canals were dried and sealed with CaOH (Ultracal, Ultradent, USA).In the second session, CaOH was removed under the operating microscope using 2.5%NaOCl and 17%Edta.Tooth #12 was filled with warm vertical guta percha condensation and bioceramic based root canal paste(Sure-Seal Root, Sure-endo,Gyeonggi-do, SouthKorea).Tooth#21 was filled with Mineral Trioxide Aggregate(MTA)(Orthomta, Daejeon, Korea) and the access cavities were restored using composite.

Bioceramics are promising because of their antibacterial and anti-biofilm properties in addition to the biocompatible nature of the material. This study aims to demonstrate a comprehensive solution to internal root resorption with the use of bioceramics as a filling material.

A 1-year follow-up CT scan showed that the teeth were asymptomatic and the lesions had healed. Root canal treatments using both MTA and bioceramic-based root canal paste in lesioned teeth with internal resorption yielded successful results.
