Evaluation of changes of BI, PD, alveolar bone and attachment level were given before and after treatment by means of periodontal probe, periapical x ray film and CT scan of the involving teeth. 使用牙周临床检查、常规根尖片、前牙区CT来观察比较正畸治疗前后患牙的牙龈出血、探诊深度、牙槽骨高度和附着水平的变化。
Objective To compare the reproducibility of probing depth ( PD) measurements using the Florida probe and the conventional periodontal probe. 目的比较Florida探针与普通牙周探针测量牙周袋深度(probingdepth,PD)的重复性。
