Introduction: This study aimed to estimate the prevalence of the most frequent oral and systemic manifestations in human immunodeficiency virus-1 (HIV-1)-positive patients.
Methods: The study was conducted on 300 HIV-1 patients attending the Reference Unit Specialized in Special Infectious Parasitic Diseases in Belém, Pará, Brazil.
Results: The most prevalent oral conditions were caries (32.6%), candidiasis (32%), and periodontal disease (17%). Among the systemic manifestations, hepatitis (29.2%), gastritis (16%), arterial hypertension (14.7%), and tuberculosis (12%) were the most commonly observed.
Conclusions: We here reported on the most prevalent oral and systemic conditions in HIV-1-positive patients. The healthcare professional's knowledge of the various manifestations among these patients is fundamental to ensure prompt and accurate diagnosis and treatment, and for improving the quality of life of these patients.
