Introduction
The present review aimed to focus on the studies on halitosis prevalence and related parameters in general population and periodontal patients because the number of epidemiological researches on halitosis is limited. In this review, PubMed-MEDLINE and Lilacs/SciELO were searched through February 2014 for appropriate studies. ‘Volatile sulphur compounds’, ‘halitosis’, ‘periodontitis+halitosis’ and ‘prevalence+halitosis’ were selected as outcome variables.
Discussion
The review showed different prevalence of halitosis between 2% and 87% in the general population. Halitosis-related parameters such as periodontal disease, older age, men, tongue coating were more association with high levels of halitosis.
Conclusion
Hence, one standard protocol should be created to make the comparison of the studies easy and to show the real prevalence of halitosis around the world, because there is no uniformity in evaluation methods and diagnosis in the prevalence and related parameter studies on halitosis.
