Evaluation of the effects of periodontal status according to 2017 classifications on oral health‐related quality of life and quality of life‐related to general health: A cross‐sectional study

Abstract Background In patients with periodontal disease, various symptoms are observed along with inflammation. The impact of local and systemic inflammation on periodontal tissue is well‐known; however, the impact of periodontal disease on the individual's quality of life is unclear. This study aimed to assess oral health‐related and general health‐related quality of life in patients undergoing maintenance treatment following treatment for periodontitis (RP‐CPH), patients with gingivitis (G) and patients with Stage I periodontitis (SI‐P) and to compare this with individuals with clinical periodontal health (IP‐CPH). Method This study was comprised of cross‐sectional periodontal assessment along with questionnaires. Oral health‐related quality of life and general health‐related quality of life were assessed using, respectively, the Oral Health Impact Profile‐14 (OHIP‐14) and Short‐Form‐36 (SF‐36) questionnaires. Study participants were classified according to the classification of periodontal and peri‐implant diseases and conditions established by the 2017 World Workshop. Results The OHIP‐14 total scores for the 166 study participants (age range: 22–57) of the G (11.61 ± 3.21) and SI‐P (13.03 ± 3.47) groups were significantly higher than the OHIP‐14 total scores of the IP‐CPH (1.09 ± 1.58) and RP‐CPH (2.95 ± 2.58) groups. SF‐36 scores were found to be significantly lower in the SI‐P group in all subgroups compared to the G and IP‐CPH groups. Conclusions A correlation was found between early‐stage periodontal disease and low levels of OHRQoL and GHRQoL. The health of periodontal tissues may have a positive effect on the quality of life.
