32Part of the oral health care in the care network encompasses users in 33 cases of emergency. This study proposed to map the determinants of the use of 34 dental care services within the health care network to address dental 35 emergencies of the Brazilian Unified Health System (UHS) and to verify the 36 main gaps in the research in this area. This is a scoping review that took place 37 in 2018 using Andersen's behavioral model as a reference. A total of 16 studies, 38 out of 3786 original articles identified, were included and reviewed. Two 39 reviewers independently conducted the selection process and the decision was 40 consensually taken. The mapping of the determinants revealed a greater 41 number of enabling factors and a larger gap in results. Greater use of the 42 emergency service was registered by people in pain, women, adults, from an 43 urban area, with a lower income, and less education. In future studies, primary 44 surveys are recommended, which include all ages, analyzing different groups of 45 needs and users that take into account the country's northern region and the 46 different subjects pointed out in this review.

Introduction
57The majority of oral diseases is chronic and share several determinants 58 with other chronic non-transmissible diseases. Among the different oral 59 diseases, untreated dental caries registers the most prevalent, affecting almost 60 half of the world population, with a negative impact on the quality of life. The 61 pain caused by untreated dental caries affects the quality of sleep and the 62 ability to eat, it slows growth and negatively affects social life [1,2].
63Since 1988, Brazil's Unified Health System (UHS) is attempting to build a 64 humanized care model, centered on the patient, and has been coordinating 65 services and shaping actions for the promotion, prevention and care in Primary
66Health Care (PHC) through the Family Health Strategy, but has also been 67 reorganizing other points of the care networks. The network conformation has 68 the intent to address the multiple health care challenges in a fragmented system 69 primarily oriented by acute conditions. Availability, access, and the ability to 70 quickly transition between health care providers are the defining elements of a 71 good or otherwise unsatisfactory network interface[3]. 72 The expansion of oral health care in Brazil since the establishment of the 73 UHS is undeniable, with the organization of priority programmatic actions, such 74 as the expansion of primary care, specialized dental care and support services, 75 care provided to pregnant women and children, and emergency services[4]. The 76 guarantee of care provided to patients in acute conditions in public services is 77 an ethical principle found in the guidelines of the National Policies of 78 Humanization, Primary Care, Oral Health and Emergency Care (National Policy 79 of Emergency Attention -NPEA)[5-8]. The network structure of emergency 80 care with settled flows intends to address acute cases according to their risk ...
