Abstract(s)
O termo xerostomia corresponde a um sintoma definido como perceção, pelo indivíduo, de sensação de boca seca. Sendo subjetiva, esta sensação não corresponde, necessariamente, a uma diminuição objetiva da quantidade de saliva (hipossialia). Assim, a xerostomia pode ser classificada como xerostomia primária, como resultado de um anormal funcionamento das glândulas salivares, ou como xerostomia sintomática (pseudo-xerostomia), em que o individuo tem a sensação de secura oral, mesmo que num contexto de adequada secreção salivar, ainda que com alterações qualitativas e/ou quantitativas dos seus constituintes.
A xerostomia apresenta uma prevalência elevada na população. Há mais de 400 medicamentos que causam xerostomia, para além de estar, também, associada a diversas patologias, principalmente crónicas e de elevada prevalência. Quando não tratada, a xerostomia pode comprometer significativamente a qualidade de vida dos doentes. Com esta dissertação, através de uma revisão da literatura, pretende-se apresentar a etiopatogenese, manifestações clínicas, diagnóstico e tratamento da xerostomia, à luz do conhecimento atual.
The term xerostomia refers to a symptom defined as the perception, by the individual, of the feeling of dry mouth. Being subjective, this feeling does not, necessarily, correspond to an objective decrease of saliva (hypossialia). Therefore, xerostomia may be classified as primary xerostomia, as a result of an abnormal function of the salivary glands, or as symptomatic xerostomia (pseudo-xerostomia), in which case the individual has the feeling of oral dryness, even in a context of adequate salivary secretion, although with either qualitative and/or quantitative alterations of its components. Xerostomia has a high prevalence in the general population. Over 400 drugs are known to cause xerostomia and it is also associated with several pathologies, most of them chronic and highly prevalent. When gone untreated, xerostomia may significantly compromise patients` quality of life. With this dissertation, through a literature review, it is intended to present the etiopathogenesis, clinical manifestations, diagnosis and treatment of xerostomia, in light of current knowledge.
