Digital Assessment of the Knowledge, Attitudes and Preparedness of Dentists towards Providing Dental Treatment to People Living with HIV in Northern Brazil

People living with HIV (PLWH) continue to face stigma and discrimination during dental treatment in Brazil. This study aimed to describe the sociodemographic, educational and professional characteristics of dentists working in the Northern Brazilian region and to identify the level of knowledge of these health professionals in relation to the care and management of PLWH using a digital form. Methods: This cross-sectional study was population-based among dentists and was conducted between July and December 2021. A total of 396 dentists were invited using the “snowball” sampling technique and received an anonymous digital form (Google(®) Forms platform) composed of four blocks of dichotomous and multiple-choice questions. After signing the informed consent form, dentists were divided into seven groups according to the amount of time that had passed (in years) since they had completed their bachelor’s degree in dentistry. A total of 25 questions referring to sociodemographic, educational and professional factors and knowledge about the dental care of PLWH were asked, and all data were presented as descriptive percentages and then analyzed using the Kappa test. Results: The average age was 31.9 years, and the states of Pará and Amazonas presented better knowledge about the dental care of PLWH. Dental prostheses (62/381-16.3%), orthodontics (57/381-15%) and periodontics (56/381-14.7%) were the most cited dental specialties, and demographic, professional and epidemiological characteristics showed a statistically significant difference regarding knowledge (<0.0001). Conclusions: The knowledge of dentists in Northern Brazil is partially high, although there is some lack of knowledge about the dental care of PLWH.
