Most oral conditions have a multifactorial etiology; that is, they are modulated by biological, social, economic, cultural, and environmental factors. A consistent body of evidence has demonstrated the great burden of dental caries and periodontal disease in individuals from low socioeconomic strata. Oral health habits and access to care are influenced by the social determinants of health. Hence, the delivery of health promotion strategies at the population level has shown a great impact on reducing the prevalence of oral diseases. More recently, a growing discussion about the relationship between the environment, climate change, and oral health has been set in place. Certainly, outlining plans to address oral health inequities is not an easy task. It will demand political will, comprehensive funding of health services, and initiatives to reduce inequalities. This paper sought to give a perspective about the role of social and physical environmental factors on oral health conditions while discussing how the manuscripts published in this Special Issue could increase our knowledge of the topic.

Telehealth uses Information and Communication Technologies (ICT) in distance health-related activities between professionals, managers, and patients of health services. This cross-sectional study compared the ICT infrastructure available in Brazilian Basic Health Units (BHU) for telehealth actions, along with evaluation cycles of the National Program for Improving Access and Quality of Primary Care (PMAQ-AB). Data from the second and third cycles of the PMAQ-AB were used. A total of 22,021 BHUs were evaluated concerning the availability of computers, cameras, stereo boxes, microphones, printers, television, and internet available. The presence of each ICT equipment assigned a score to each BHU. The sum of these scores assigned a final score to the BHU and was used for comparison among different Brazilian regions. The data were analyzed descriptively and by Wilcoxon test (p ≤ 0.05) using SPSS v. 25. The increase in the median number of ICT equipment was statistically significant in the BHU in Brazil and the Brazilian regions (p < 0.001). The South, Southeast, and Midwest regions had the highest median scores in both cycles. The availability of ICT equipment for telehealth actions in BHU improved over the PMAQ-AB cycles, with differences in the ICT structure between Brazilian regions.

Access to quality healthcare is an essential component of health policy. This cross-sectional study describes the actions performed by Brazilian Oral Health Teams (OHTs) analyzed in the National Program for Improving Access and Quality of Primary Care and the relationship of contextual aspects. A total of 22,993 OHTs that participated in the third cycle of the referred program were evaluated using a structured questionnaire. Thirteen procedures (items) related to spontaneous dental care and preventive, surgical, restorative, prosthetic, and oral cancer prevention or diagnosis were assessed. Item response theory was used to estimate the performance scores of OHTs, based on 13 items. The relationship between performance scores and contextual variables in Brazilian regions was analyzed by thematic maps and Spearman correlation (p < 0.05). The highest difficulty parameters were for questions related to prosthetics (b = 0.879) and actions for oral cancer (b = 2.922). The 13 items were more appropriate to discriminate the teams with lower performance and relatively ineffective in differentiating those with better performance. A direct relationship with the Human Development Index (r_s = 0.249; p = 0.004) and an indirect relationship with the Gini Index (r_s = −0.482; p < 0.001) were found. Contextual aspects presented a relationship with the performance of the Brazilian OHTs. The evaluated items showed some potential to discriminate the performance of OHTs since many of the evaluated dental procedures are performed by most of the teams.
