Viral Upper Respiratory Infections Allergic Rhinitis and Conjunctivitis Otitis Media Sinusitis Laryngitis and Laryngotracheobronchitis Pharyngitis and Tonsillitis

Respiratory infections are commonly encountered among dental patients. Commonalities between chemotherapeutic options and the anatomic proximity with the oral cavity lead to much interplay between oral and respiratory infections. There is a growing body of literature pointing to a direct association between oral pathogens and respiratory diseases. Recent studies have reported on oral bacteria as causative pathogens in respiratory diseases and conditions associated with significant morbidity and mortality. Furthermore, some respiratory illnesses (such as asthma) may have an effect on orofacial morphology or even on the dentition. This chapter discusses the more common respiratory illnesses and explores the relationship between these conditions and oral health.
