Dental imaging is a specific part of biomedical imaging that not only includes many of its particularities but also presents several specificities. Oral public health impacts especially vulnerable populations that face precarious hygiene conditions. In recent years, the use of computational technologies for evaluation, diagnosis, prevention and treatment of oral diseases increased, promoted by the advent of digital radiology and artificial intelligence. However, these solutions in dental imaging are not so popular in all regions, as it is in high-income regions due to several factors such as resistance from specialists to incorporate computational solutions in their clinical routine and the lack of access to health services and available data. Nevertheless, there are efforts to develop technology in this field aiming the identification, classification, segmentation, and prediction of oral issues in digital radiographs, resulting in applications such as orthodontics and aesthetics. Moreover, artificial intelligence techniques have recently emerged showing impressive results in different areas. This article briefly presents three use cases of solutions for oral health, developed in a research center which is part of a public health center in Brazil. We also assess the importance of the development of medical AI-based technologies in low and middle-income regions.
