Aim:
The aim of this study was to determine the impact of non-surgical periodontal therapy (NSPT) on oral health-related quality of life (OHRQoL) of a selected group of the Malaysian population at the primary dental care setting.
Participants and Methods:
This study was conducted from year 2021 to 2022. Patients attending four government dental clinics in Kinta district were included in the study after basic periodontal examination was conducted. The sample size was calculated using the NCSS PASS 11 power analysis and sample size, and a final sample size of 94 was used. A short version of the Malaysian Oral Health Impact Profile (S-OHIP[M]) questionnaire was given as a baseline before the intervention. NSPT was provided in a single session or by a quadrant approach. Patients were then called for review after 6 weeks during when they were required to complete the S-OHIP(M) questionnaire again. All data were then entered and analysed using SPSS version 26.0.
Results:
The prevalence of impact decreased significantly post-treatment (n [%] pre vs. post: 91 [96.8%] vs. 70 [74.5%]; P < 0.001). A significant decrease was observed in the severity of impact (additive score) (median [interquartile range (IQR)] pre vs. post: 8.5 [5.0–15.0] vs. 2.0 [0.0–6.0]; P < 0.001) and extend of impact (simple count score) (median [IQR] pre vs. post: 0.5 [0.0–2.0] vs. 0.0 [0.0–0.0]; P < 0.001) post-treatment compared to pre-treatment too.
Conclusion:
The OHRQoL status amongst gingivitis and mild-to-moderate periodontitis patients in primary care has improved after treatment.
