utta‑percha, calcium silicate‑based materials, fiber posts, and composite restorations.[5‑7] Although these methods provide satisfactory sealing ability, they may not adequately reinforce weakened dentin or restore biomechanical integrity. Recent biomimetic restorative concepts have emphasized preservation and reinforcement of compromised tooth structure using fiber‑reinforced composite materials.[5,6] Polyethylene fibers incorporated within composite resin have been shown to improve stress distribution and reduce crack propagation by functioning as an internal splint.[6] Similarly, the Bio block or Bio‑Bulk concept using short fiber‑reinforced composite has been proposed for reinforcement of structurally compromised roots affected by internal resorption.[8‑10] However, reports describing conservative polyethylene fiber reinforcement combined with CBCT‑guided diagnosis and histopathologic correlation remain limited. Histopathologic examination may additionally provide biological confirmation of internal inflammatory resorption through identification of chronic inflammatory infiltrate, multinucleated odontoclast‑like cells, and resorptive lacunae adjacent to dentinal surfaces.[1] However, histopathologic correlation is infrequently documented in routine clinical reports of internal resorption. This report presents a multidisciplinary biomimetic approach incorporating CBCT assessment, histopathologic confirmation, and polyethylene fiber‑reinforced composite restoration for management of structurally compromised internal inflammatory resorption.
