In recent years, many types of dental lasers or other devices have been used for the non-surgical treatment of periodontal diseases. However, it remains unclear whether the combined application of laser and air polishing is effective as an adjuvant treatment for periodontitis. The purpose of this study is to compare the use of combined application of Er:YAG laser and sub-gingival air polishing powder, with the treatment of Er:YAG laser only, in periodontal diseases treatment in a Chinese population.",[79],"Periodontitis",[81],"generalized, stage Ⅱ or stage Ⅲ","2025-02-05",{"date":84,"type":85},"2025-02-07","ACTUAL",{"date":87,"type":85},"2024-09-04",{"date":89,"type":73},"2027-12",{"name":5,"class":6},1]
