Conservative Management of Invasive Cervical Resorption Using Biodentine With Adjunctive Laser-Assisted Photodynamic...

Invasive cervical resorption (ICR) is an aggressive form of external root resorption that can cause significant structural damage if not detected early. This case report describes the conservative management of ICR using Biodentine (Septodont, Saint-Maur-des-Fossés, France) with adjunctive laser-assisted photodynamic therapy (PDT) and photobiomodulation therapy (PBM) to enhance disinfection and promote healing. A 53-year-old female patient presented with a fractured maxillary central incisor and was diagnosed with Heithersay Class III ICR. Endodontic treatment was initiated, followed by surgical exposure of the resorptive defect. Granulation tissue was removed using an erbium-doped yttrium aluminum garnet (Er:YAG) laser (2,940 nm). Antimicrobial PDT was performed using 0.01% methylene blue activated with a 660 nm diode laser. The defect was restored with Biodentine. Postoperative PBM using an 810 nm diode laser was applied after suturing to enhance soft tissue healing. Postoperative evaluation demonstrated satisfactory soft tissue healing at the surgical site without signs of inflammation or infection. Radiographic examination revealed restoration of the cervical defect with Biodentine and preservation of the surrounding periodontal structures. This multimodal laser-assisted approach may represent a predictable and minimally invasive strategy for the management of ICR.
