ABSTRACT Objectives Periodontal disease is a disease that progresses asymptomatically in the first stage, but affects the lives of individuals socially, psychologically and functionally. In order to measure the effect of this disease on quality of life, periodontal conditions of underground mine workers in Zonguldak province were determined and the relationship between periodontal status and quality of life was evaluated. Material Methods 255 volunteered miners were visited and Community Periodontal Index and Treatment Needs (CPITN), papillary bleeding index and periodontal status were determined. Afterwards, sociodemographic data, oral hygiene habits, bleeding and bad breath findings and Oral Health Impact Profile-14 (OHIP-14) scale were completed. Results According to the results obtained; education level, number of teeth, dental habits, presence of bleeding, bad odor and smoking were found to affect OHIP-14 levels. There was no relationship between CPITN, in which periodontal status was evaluated, and Oral Hygiene Impact Profile-14 (OHIP-14) index. Conclusions In conclusion, although some variables such as education, dental health and social habits and number of teeth had an effect on OHIP-14, no significant relationship was found between periodontal status and quality of life.
