Abstract
To relate the clinical effects of two different forms of non-surgical periodontal therapy - scaling and root planing per quadrant (SRP-Q) and one-stage full-mouth disinfection (FMD) - to patient-based outcomes such as fear, anxiety, and pain of moderate chronic periodontitis patients. Dental Fear Survey (DFS) and Dental Anxiety Scale (DAS) questionnaires and Visual Analogue Scale (VAS) were applied to 78 patients randomized into two groups: SRP-Q (n=37) and FMD (n=41). Periodontal clinical parameters: probing pocket depth (PD), clinical attachment level (CAL), plaque index (PI), and gingival index (GI) were monitored at baseline and 6months after treatment. Data were statistically analysed by chi-square, Fisher's exact, Mann-Whitney, Wilcoxon tests, Pearson's correlation, and Cluster analysis. All periodontal clinical parameters improved from baseline to 6months. Patients with higher fear and anxiety showed a worse clinical periodontal status before and after treatment (mean CAL, PI, and GI). After both types of treatment, fear and anxiety decreased (FMD: p=0.019; SRP-Q: p=0.043) with no differences between the groups. Pain did not differ between groups (FMD: 20.6±19.0 and SRP: 20.7±20.0; p=0.930). In moderate chronic periodontitis patients, SRP-Q and FMD provided periodontal clinical improvements and similar experiences of fear, anxiety, and pain.
