RESUMEN
The aim of this study was to use a qualitative approach of an exploratory nature to analyze the knowledge and practice of a nursing staff at Hospital Infantil Joana de Gusmão as regards oral health. The sample consisted of 2 nurses and 10 nursing technicians. Data collection was carried out through semi-structured interviews and the content was analysed considering 2 thematic groups: practice and oral health knowledge and meanings of health care. The results revealed a lack of attention concerning oral health care in child patients undergoing antineoplastic treatment. It could be concluded that there is a clear need to adopt measures directed towards oral health care to promote patient health and quality of life. Furthermore, training courses on oral health in oncology, as well as the inclusion of a dentist on the hospital staff, are also suggested.
