Relations between periodontal status, oral health–related quality of life and perceived oral health and oral health consciousness levels in a Turkish population

OBJECTIVES: This study aimed to evaluate the interrelationship of periodontal status, socio-demographic characteristics, perceived oral health and oral health consciousness levels as well as the impact of these factors on quality of life using a questionnaire and the Oral Health Impact Profile-14(OHIP-14) scale. METHODS: Seven hundred and fifty systemically healthy individuals aged ≥18 years referred to a Periodontology Department were included in the study. The OHIP-14 scale and survey were applied to identify socio-demographic characteristics, oral hygiene characteristics, perceived oral health and oral hygiene consciousness levels. Three groups were established based on periodontal status (periodontally healthy [H], gingivitis [G] and periodontitis [P]) determined using periodontal indexes, and the relationship between the above-mentioned factors and periodontal status with quality of life was assessed. RESULTS: Oral health-related quality of life differed significantly by gender, marital status, education level, oral hygiene habits and periodontal status. A statistically significant positive relationship was found between high OHIP-14 scores and unfavourable socio-demographic characteristics, increased severity of periodontal disease, and irregular dental care practices. The perceived oral health and oral health consciousness levels significantly differed due to periodontal status. CONCLUSION: Periodontal status, gender, marital status, education level, dental care practices, perceived oral health and oral hygiene consciousness levels are important determinants of oral health-related quality of life (Clinical Trial No. NCT03549247).
