RESUMO
OBJECTIVE: The aim of this study was to investigate the impact of periodontitis on oral health-related quality of life (OHQoL) using Oral-Dental Health-Related Quality of Life-United Kingdom (OHRQoL-UK) scale and evaluate the contributing factors. METHODS: 50 patients with untreated periodontitis and 50 individuals without periodontitis were enrolled in the study. All subjects received detailed periodontal examination. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) measurements were examined. OHRQoL was assessed by the Oral Health Quality of Life-United Kingdom (OHRQoL-UK) scale. Symptoms of periodontitis were monitored by visual analogue scale (VAS). Socio-demographic characteristics, medical history, smoking status, hygiene habits of the participants were recorded. This study is registered at ClinicalTrials.gov as NCT04240014. RESULTS: Total OHRQoL-UK scores were 38.24±6.47 in periodontitis patients and 55.88±9.38 in non-periodontitis individuals (p < 0.001). The scores of all 4 parameters were significantly lower in patients with periodontitis compared to healthy individuals (p <0.001). Higher PI, GI, PD and CAL values were associated with extensive negative impacts of periodontitis on OHRQoL (p < 0.001). According to the results of linear regression analysis, only periodontitis was found to associate with OHRQoL. Periodontal disease reduces the total quality of life score by 15.087 (ß= -15.087; 95% CI = [(-18.934)-(-11.240)]. CONCLUSIONS: Individuals with periodontitis has diminished OHRQoL compared to healthy individuals.
