Abstract: Objective: To evaluate the cementum thickness and the root morphology after SRP treatment with or without periodontal endoscope in vitro. Methods: Thirty single root teeth with mobility Ⅲ which need to be extracted were collected and divided into 4 groups randomly: no treatment, Ultra group, Ultra-Hand group, and Ultra-Endo group. Plaque Disclosing Agent was used to measure the residue calculus rate. SEM was applied to observe the surface of teeth. Histology method was taken to measure the thickness of cementum. Results: All three test groups had a much lower calculus residual rate than control group (P<0.05), and both Ultra group and Ultra-Hand group had more calculus residual than Ultra-Endo group (P<0.05). Ultra-Hand group showed a smooth surface with homogeneous patchy distribution and cobblestone appearance with debris. Ultra-Endo group and Ultra group showed roughness, and the cobblestone was the same as the surface of health teeth under EMS. The remaining cementum of Ultra-Endo group was more than those of Ultra group and Ultra-Hand group. Conclusions: Subgingival calculus can be removed more thoroughly and clearly and remain more cementum with the help of periodontal endoscope.
