XEROSTOMIA IN ONCOLOGICAL PALLIATIVE CARE: THE ROLE OF THE DENTIST IN PROMOTING COMFORT AND DIGNITY

Abstract

This study aims to highlight xerostomia as a highly prevalent oral manifestation in oncology patients under palliative care, emphasizing its underreporting and the essential role of the dentist in promoting comfort and dignity for these individuals. It is an integrative literature review conducted through searches in the SciELO, PubMed, BVS, and Google Scholar databases, covering publications from 2016 to 2025, with the inclusion of selected classical references and updated access in 2025. After applying inclusion and exclusion criteria, twenty studies addressing the relationship between xerostomia, oncology, and palliative care were selected for analysis. The findings indicate that xerostomia, often referred to as an “orphan symptom,” remains underdiagnosed and poorly addressed in clinical practice, despite its direct impact on patients’ well-being and quality of life. In advanced stages of the disease, when patients are debilitated and frequently unable to express their discomfort, the recognition and management of this condition become even more relevant. Within this context, the dentist plays a crucial role as part of the multidisciplinary team, being qualified to identify xerostomia early, implement preventive strategies, and provide interventions that promote comfort and alleviate suffering. It is concluded that the effective inclusion of dentistry in palliative care is indispensable for a comprehensive and humanized approach, ensuring that oncology patients receive attention, care, and respect even in the final stages of life.
