Abstract:
BACKGROUND: The purpose of this study was to investigate the effect of two modes of delivery of non-surgical periodontal therapy on patient experience of pain and oral health-related quality of life (OHQoL). METHODS: Fifty-nine patients with mild to moderate periodontitis received non-surgical therapy using a piezo-ceramic device (n = 30) or curets (n = 29). Periodontal examinations were carried out at baseline and 8 weeks following therapy. Subjects completed the short-form McGill pain questionnaire, visual analog scales regarding sensitivity and satisfaction, and the United Kingdom OHQoL questionnaire (OHQoL-UK) at baseline, treatment, and 1, 4, and 8 weeks. RESULTS: Both groups showed improvements in clinical parameters with no significant differences between the groups. Pain scores and OHQoL-UK showed no significant differences between the groups. After treatment, OHQoL-UK scores improved from an initially negative effect on quality of life to a level of no effect. Differences in sensitivity scores between the groups were statistically significant at 1 week (P = 0.011), 4 weeks (P = 0.005), and 8 weeks (P = 0.025), favoring the use of the piezo-ceramic device. CONCLUSIONS: In mild to moderate periodontitis, therapy had a small positive impact on pain and OHQoL-UK scores. These data support the concept that periodontitis may negatively affect a patient's quality of life and that treatment may improve it.
