Abstract: Objective To understand preoperative anxiety and postoperative quality of life in patients with periodontally accelerated osteogenic orthodontics (PAOO) surgery, and provide a theoretical basis for preventing preoperative anxiety and improving postoperative quality of life in PAOO surgery. Methods According to the inclusion and exclusion criteria, 45 patients with PAOO surgery were randomly selected. All patients were asked to answer the following questionnaires which included self-rating anxiety scale (SAS), modified dental anxiety scale (MDAS), pain evaluation (VAS visual pain scale), clinical performance evaluation (swelling, bleeding, nausea, oral odor), and oral function evaluation (chewing, speaking, sleeping, working). Data analysis was performed using SPSS 18.0 software. The quantitative and qualitative statistical description methods were used to evaluate the preoperative anxiety and postoperative quality of life of patients with PAOO surgery. Results The preoperative SAS score of the 45 patients was 44.28±11.15, among whom 10 patients had anxiety accounting for 22.22%. The preoperative MDSA score was 9.29±2.78, among the 45 patients, 8 patients had anxiety accounting for 17.78%. The VAS values 1, 3, 5, 7, and 10 days after surgery were moderate pain (7.13±1.04), mild pain (3.98±1.05), mild pain (1.96±0.85), and painless (0.31±0.51), painless (0.09±0.28). The most common discomforts after PAOO surgery were swelling and bleeding. The degrees of swelling 1, 3, 5, 7, and 10 days after surgery were 100.00%, 100.00%,100.00%, 95.66%, 6.67%. The degrees of bleeding 1, 3, 5, 7, and 10 days after surgery were 97.78%, 17.78%, 8.89%、4.44%, 0.00%. The most common discomforts of oral function after PAOO surgery were the effects on chewing and speech. The degrees of the effects on chewing condition 1, 3, 5, 7, and 10 days after surgery were 100.00%, 97.78%, 73.33%, 11.11%, 4.44%. The degrees of the effects on speech condition 1, 3, 5, 7, and 10 days after surgery were 100.00%, 97.78%, 77.78%,11.11%, 4.44%. Conclusion Approximately 15.38% of the patients have dental anxiety before PAOO surgery. The main clinical symptoms after surgery are moderate to mild pain, varying degrees of swelling, bleeding, disturbance in chewing and speech in 1-7 days after surgery. It is suggested that the clinicians should design the reasonable surgical method and optimize the nursing process to relieve the patients’ anxiety and postoperative discomforts.
