The association between stage-grade of periodontitis and sleep quality and oral health-related quality of life

Background Inadequate sleep increases inflammatory and proinflammatory markers among many other influences. Due to its potential to influence inflammation and oxidative stress, which are the main pathogenetic mechanisms actually recognized in the periodontal damage, poor sleep quality could be a factor for periodontitis and quality of life (QoL). In this context, the aim of this study is to investigate the association of stage-grade of periodontitis with sleep quality. and the effect of periodontitis on QoL. Methods The study consisted of clinical examination and a questionnaire. The questionnaire was based on demographic information, Oral Health Impact Profile-14 (OHIP-14), and Pittsburgh Sleep Quality Index (PSQI). Patients were diagnosed according to the 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions. Clinical examination included probing depth (PD) and clinical attachment loss (AL). Results The mean age of 99 participants was 30.27 +/- 5.80 years ranging from 18 to 40-years. The mean clinical values of the patients in this study included AL, 4.03 +/- 2.46 mm, and PD, 4.27 +/- 1.55 mm. The mean of the global OHIP-14 score was 13.43 +/- 6.23 and the mean PSQI global score was 6.57 +/- 3.53. Conclusions Stage-grade of periodontitis was associated with short sleep duration, low-sleep quality, and low oral health-related quality of life.
