This study aims to conduct a systematic review to determine the prevalence of halitosis in adolescents and adults.
Electronic searches were performed using four different databases without restrictions: PubMed, Scopus, Web of Science, and SciELO. Population-based observational studies that provided data about the prevalence of halitosis in adolescents and adults were included. Additionally, meta-analyses, meta-regression, and sensitivity analyses were conducted to synthesize the evidence.
A total of 584 articles were initially found and considered for title and abstract evaluation. Thirteen articles met inclusion criteria. The combined prevalence of halitosis was found to be 31.8% (95% CI 24.6-39.0%). Methodological aspects such as the year of publication and the socioeconomic status of the country where the study was conducted seemed to influence the prevalence of halitosis.
Our results demonstrated that the estimated prevalence of halitosis was 31.8%, with high heterogeneity between studies. The results suggest a worldwide trend towards a rise in halitosis prevalence.
Given the high prevalence of halitosis and its complex etiology, dental professionals should be aware of their roles in halitosis prevention and treatment.
本研究旨在进行系统评价，以确定青少年和成年人口臭的患病率。
无限制地使用四个不同的数据库（PubMed、Scopus、Web of Science 和 SciELO）进行电子检索。纳入了提供有关青少年和成年人口臭患病率数据的基于人群的观察性研究。此外，还进行了荟萃分析、荟萃回归和敏感性分析，以综合证据。
最初发现了 584 篇文章，并对其标题和摘要进行了评估。符合纳入标准的文章有 13 篇。口臭的总患病率为 31.8%（95%CI 24.6-39.0%）。出版年份和开展研究的国家的社会经济地位等方法学方面似乎影响了口臭的患病率。
我们的结果表明，口臭的估计患病率为 31.8%，各研究之间存在高度异质性。结果表明，口臭患病率呈全球上升趋势。
鉴于口臭的高患病率及其复杂的病因，牙科专业人员应意识到他们在口臭预防和治疗中的作用。
