Periodontal treatment impact on halitosis and quality of life

Before starting the prospective longitudinal study, we intend to carry out a thorough review of the subject, searching electronic databases, complemented by checking bibliographies of review articles. Thus, the first task of the study is to conduct a systematic review of halitosis, diagnosis and treatment methods, and their impact on quality of life. We also intend to conduct a systematic review on the topic: subgingival microbiome in patients with periodontitis.
