简要概括
The main cause of endodontic disorders is microbial infection. From the infected root canal, microorganisms can penetrate into the deeper layers of root dentine and propagate a periapical tissue through the apical foramen and lateral canals. Eliminating microorgnims is the primary objective of endodontics in order to create an environment as free of bacteria as possible. This will favor the environment for healing wi...显示更多
详细描述
Cone beam computed tomography (CBCT) has become a cornerstone in endodontic imaging, providing high-resolution, three-dimensional visualization of complex anatomical structures. CBCT enhances diagnostic precision and treatment planning beyond what is achievable with two-dimensional radiograph. It has been shown to be more accurate than digital periapical radiographs in the long-term assessment of root canal treat¬men...显示更多

实验性Group I (Diode laser group)
Laser activated disinfection will be performed using 810 nm diode laser (Elexxion clarosdental laser, Singen Deutschland, Germany) in a continuous wave mode with a power of 1.5 Watts in 4 cycles of 5 seconds with 20 seconds intervals in between each. Prior to irradiation, all the individuals in the room will wear protective laser safety eye glasses. A 200 μm fiber optic tip (Lite medics, Italy) will be inserted 1 mm ...显示更多

实验性Group II (Calcium hydroxide group)
Calcium hydroxide paste (MetaBiomed, Chungcheongbuk-do, Korea) will be placed inside the root canal and left for 1 week. The access cavity will be temporarily sealed with light cure glass ionomer resin cement. After 1 week, the temporary filling will be removed following local anaesthesia and isolation, the root canal will be irrigated with 20 ml saline and gently filed using H file corresponding to the master apical...显示更多
