Background/purpose: Dental anxiety is prevalent and may result in the avoidance of periodontal therapy and maintenance. This study aimed to explore the impact of non-surgical periodontal treatment (NSPT) on dental anxiety among patients with periodontitis. Materials and methods: In this study, 122 patients with periodontitis participated. The Chinese version of the Modified Dental Anxiety Scale (MDAS) gauged baseline dental anxiety during the initial appointment. Patients receiving non-surgical periodontal treatment (NSPT) in subsequent appointments formed the NSPT group, while those with a delayed NSPT of at least two months constituted the delayed group. In the NSPT group, the second termination questionnaire was administered one month post the last NSPT visit, just before the periodontal re-evaluation. In the delayed group, the second questionnaire was completed before the delayed NSPT initiation. Results: Baseline MDAS scores were comparable between the delay and NSPT groups. However, the NSPT group exhibited lower total scores and scores for each of the five MDAS items at termination compared with the delay group. At baseline, MDAS total scores were inversely associated with age and were lower in males. A reduction in MDAS total scores between observation points was correlated with NSPT, sex, and age after adjustment. Regarding MDAS item 4 (teeth scaled/polished), score reduction consistently correlated with NSPT and age. Conclusion: Participation in NSPT may alleviate dental anxiety, and consequently enhance the patients' conceptiveness to undergo periodontal maintenance or surgery.
