Periodontal diseases and potential risk factors in Egyptian adult population—Results from a national cross-sectional study

Abstract

Background Despite the interdependence of general and periodontal health, there is paucity of national representative data on the prevalence of periodontal diseases and their associated risk factors in Egyptian population. This cross-sectional study, thus, aimed to assess the prevalence of periodontitis and tooth loss among Egyptian adults and investigate the association between potential risk factors and periodontal diseases. Methods A total of 5,954 adults aged ≥ 20 years were included in this study as a subsample from Egypt’s national oral health survey. Periodontitis was diagnosed with Community Periodontal Index ‘CPI’ scores ≥3 and tooth loss not due to caries was included in the analysis. Socio-demographic data and information on behavioral factors and history of diabetes were gathered in a face-to-face interview. Logistic regression was done to interpret the impact of potential predictors on the incidence of the two selected outcome variables. Results The overall prevalence of periodontitis was 26% and regression analysis revealed that higher odds of periodontitis existed among illiterate participants (OR = 1.74; 95% CI: 1.40–2.17), smokers (OR = 1.93; 95% CI: 1.69–2.20) and rural residents (OR = 1.16; 95% CI: 1.03–1.30). On the other hand, old age, frequency of dental attendance and history of diabetes were the main predictive factors for tooth loss. Conclusions Among Egyptian adults, periodontal diseases were strongly associated with a multitude of modifiable and non-modifiable risk factors and inequalities in distribution of periodontal treatment needs were determined mainly by age, gender, level of education and residency location.

“…As a result, the impact of PD on general health has been increasing to focus on research interests. Acknowledging that PD is both preventable and irreversible, many countries have initiated efforts to reduce the burden of PD [ 7 ].…”

Prevalence, Predictors, and Reasons for Permanent Tooth Extraction Among High School Students in Saudi Arabia: A National Cross-Sectional Study

“…Failure to replace a missing tooth may affect balance in the stomatognathic system and trigger chains of adverse effects [4]. These may include masticatory problems and chewing difficulties, altered speech, loss of self-confidence, concern about appearance, and feelings of bereavement [5][6][7]. Tooth loss may also lead to rotation and drifting of adjacent teeth and supra-eruption of opposing teeth, which may, in turn, result in facial asymmetry or bite collapse.…”
