Abstract：Objective: To explore the influence of two correction methods of bracketless invisible appliance and self-locking bracket appliance on pain, inflammatory factors in gingival crevicular fluid and oral health score of adult orthodontic patients. Methods: A total of 108 adult orthodontic patients who were admitted from December 2018 to October 2020 were selected for the study. 54 cases were treated with self-ligating brackets (Group A) and 54 cases were treated with invisible aligners (Group B) according to the patients' wishes, and all were followed up for 6 months. The visual analogue score (VAS) was used to assess the patients' pain at 1h, 6h, 1d, 3d and 7d after treatment, to analyse the inflammatory factors in the gingival sulcus fluid before treatment and after 1, 3 and 6 months of treatment, and to assess the oral health of patients in both groups on the day of the end of the follow-up period.Results: After 6h, 1d, 3d and 7d of treatment, the VAS scores of patients in both groups showed a rising and then decreasing trend, and the scores in group B were significantly lower than those in Group A at the same time point (P<0.05).From 1 month to 6 months of treatment, the levels of IL-β and TNF-α in the gingival sulcus fluid gradually increased in both groups, and were significantly higher than those before treatment (P<0.05); the levels of IL-β and TNF-α in group B were significantly lower than those in group A at the same time point (P<0.05). After 6 months of treatment, the scores of physical pain, functional limitation, social difficulties, physical impairment, psychological communication, psychological hindrance and disability on the OHIP-14 scale were significantly higher in both groups, and the increase in each score was higher in group B than in group A (P<0.05). The composite coverage returned to normal in both groups, with 7 (12.96%) complications in group A and 4 (7.41%) in group B. The difference between the groups was not statistically significant (χ2=0.911, P=0.340). Conclusion: Compared to the self-ligating bracket method, the use of bracketless invisible aligners in adult orthodontics can reduce the patient's pain level, control the level of inflammatory factors in the sulcus and further improve the patient's oral health, which is worth promoting in relevant clinics.
