Epidemiological Investigation of Malocclusion in China
Sponsor: Shanghai Jiao Tong University School of Medicine
Summary
Malocclusion is a kind of craniomaxillofacial complex deformity caused by heredity, environment, bad habits, trauma, inflammation, tumor and aging. Notably, the last comprehensive national prevalence data on malocclusion in China, which encompassed a significant sample size, dates back over two decades. Given the evolving nature of these epidemiological metrics, such as prevalence rates, it is imperative to update our understanding. Consequently, there is an urgent need for China to undertake a unified, standardized epidemiological survey of malocclusion with a substantial sample size to ensure accurate and timely data collection.
