Prevalence of Malocclusion in Saudi Arabia – Systematic Review and Meta-Analysis
Objectives: The objective is to estimate the prevalence of malocclusion among children in Saudi Arabia using meta-analysis and to determine gender variations in the prevalence of malocclusion in Saudi Arabia.
Methods: This review conducted in adherence to PRISMA standards of quality for reporting systematic reviews and meta-analyses submitted in PROSPERO with an I.D 198427. Our systematic search included international databases including MEDLINE, EMBASE, CINAHL, PsychINFO, Scopus, Science-Direct, key journals and review articles; the date of the last search was June 2020. Methodological quality of the studies graded by means of the Quality Assessment Tool for Quantitative Studies, developed for the Effective Public Health Practice Project (EPHPP). Studies reporting overall prevalence of malocclusion for subjects under the age of 18 years were included in the study. Data analysis done by STATA version 11 software, METAN package. The standard error of the overall as well as gender based prevalence of malocclusion was calculated using binominal distribution formula. The heterogeneity index between the studies was determined using Cochran (Q) and I2 tests. Random or fixed effects model used to estimate the overall as well as gender variations of prevalence of malocclusion.
Results: Total 29 articles were eligible for the Meta analysis. Estimation of prevalence of malocclusion done in 34,263 children. Total prevalence of Class I, II, and III malocclusion was 62.6% (52.4–72.8), 28.5% (24.6–32.5), and 9.35% (8.2–10.5), respectively. The prevalence of Class I, II, and III malocclusion was 54.7% (44.8–64.6), 25.9% (22.5–29.3), and 8.15% (6.4–9.9) in boys, 50.5% (42.6–58.4), 22.35% (19.3–25.4), and 5.8% (4.7–6.9) in girls respectively.
Conclusions: Present review and meta-analysis showed a high prevalence of malocclusion among children of Saudi Arabia. Prevalence of malocclusion is higher in boys showing a gender variation.
