Background:
The aim of this study was to evaluate oral changes in patients admitted to an intensive care unit (ICU).
Material And Methods:
Retrospective, cross-sectional, descriptive study. The following data were collected at a high-complexity referral centre in northeastern Brazil between 2021 and 2024: gender, age, ventilatory support, dental condition, and type of oral change.
Results:
A total of 2,692 patients admitted to the ICU were evaluated; 52.1% of these patients were male and the mean age was 69.98 years (±19.53). Oral changes were identified in 58.41% of the patients, with odontogenic infections being the most prevalent (61.49%), followed by clinical conditions suggestive of salivary changes (15.05%) and soft-tissue lesions (9.85%). The presence of oral changes was significantly associated with males (p<0.001) aged from 50 to 59, and from 60 to 69 years (p<0.001), ventilatory support (p=0.037), being partially dentate (p<0.001), and the number of teeth (p<0.001).
Conclusions:
These data permit a characterization of the oral health status of this patient profile, reinforcing the importance of the dentist as a member of the multidisciplinary team.
