Periodontal Disease in Saudi Arabia: A Systematic Review of Prevalence and Associated Risk Factors

Background/Objectives: The oral health disorder periodontal disease is widespread around the world and has a public health dimension. This study aimed to perform a systematic review and an appraised analysis that looks at both the prevalence and diversity of risk factors associated with periodontal disease in Saudi Arabia. It places a particular focus on subgroup analyses and pooled prevalence estimates to identify certain populations that could be described as high risk. Methods: Several databases, including PubMed, Scopus, and Google Scholar, were used to conduct the present systematic review. The search was designed to identify relevant studies published from 1980 to 2023. Both quantitative and qualitative studies were included. Subgroup analyses and meta-analyses were performed using a random-effects model to calculate pooled prevalence rates. The studies were evaluated using three criteria that focused on bias. Finally, the authors created a narrative synthesis of the review findings for ease of understanding. Results: The pooled overall prevalence of periodontal disease was 46.2% (95% CI: 40.5-51.8), with high heterogeneity (I² = 85%). Subgroup analyses identified obese adults as having the highest prevalence of this condition (71.3%), and individuals diagnosed with diabetes also displayed a significantly high prevalence (52.1%). Adolescents aged 15-19 years had an age-specific prevalence of 8.6%, which was significantly lower than that of the other age groups analyzed. Poor oral hygiene, tobacco use, diabetes, and obesity have been recognized as risk factors for periodontal disease. Conclusions: The substantial burden of periodontal disease in Saudi Arabia, especially among high-risk groups, such as obese and diabetic adults, cannot be overstated. Our public health initiatives need to focus on these high-risk individuals, who are likely to be both periodontally and systemically compromised, to provide lifestyle modification counseling and oral hygiene education for them, as well as to routinize their dental care in a way that minimizes the chances of becoming periodontally compromised.
