Clinical Practice Guidelines on the Diagnosis and Treatment of Halitosis

With growing awareness of oral health and rising social expectations, the management of halitosis has attracted increasing attention, as fresh breath is essential for social etiquette and personal image. Due to the diverse origins and varying clinical manifestations of halitosis, treatment approaches differ significantly. Recent advancements have facilitated the development of more refined diagnostic tools and therapeutic methods. Based on current clinical evidence and practice, a consensus framework has been established to guide the management of halitosis. This consensus systematically outlines the prevalence and classification of halitosis, reviews its aetiology and pathogenesis, and details evidence-based diagnostic methods. Notably, it proposes tailored treatment strategies aligned with specific etiological factors. The goal is to promote the standardization, precision, and optimization of halitosis diagnosis and treatment in clinical practice.
