ABSTRACT
Restoration of endodontically treated tooth has always been a matter of restorative practice in dentistry. Endodontically treated tooth has a tendency to fracture because of the pulp is removed and significant loss of dental structure. Biomimetic restoration using fiber-reinforced composite (FRC) as post-obturation material has the ability to resist fracture and good aesthetic. A 21-year-old male presented with discomfort in eating and has no symptoms. The patient has no history of systemic disease. The intraoral clinical examination showed deep caries on the right mandibular first molar, negative on vitality, percussion, and bite test. A radiographic examination was done and showed the image of chronic apical periodontitis. The access cavity was prepared under rubber dam isolation. Root canal preparation was done by crown-down technique followed by irrigation using 5.25% sodium chloride and intracanal medicament with calcium hydroxide. The obturation procedure was conducted after seven days, using a warm vertical compaction technique and calcium hydroxide-based sealer. Considering the remaining hard tissue, a direct composite using FRC as dentine-replacing material was done. Direct restoration using FRC can be an option for restoration of the mandibular right second molar tooth with endodontic treatment.
