ABSTRACT BACKGROUND: Specific types of violence such as intimate partner sexual violence and intimate partner homicide occur more frequently in rural areas. OBJECTIVE: This study aimed to systematically review the literature on the knowledge and attitudes of rural healthcare providers regarding cases of domestic violence against women. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia. METHODS: We conducted an electronic search of six databases, which only included observational studies, regardless of the year, language, or country of publication, except for studies that used secondary data and were exclusively qualitative. Two reviewers performed the selection, data extraction, and risk of bias assessment using a specific Joanna Briggs Institute tool. RESULTS: Six studies met the inclusion criteria. All the studies had a low risk of bias. Approximately 38% of these professionals identified injuries caused by violence in patients. When asked about knowing the correct attitude to take in cases of confirmed violence, between 12% and 64% of rural healthcare providers answered positively; most of them would refer to specialized institutions and promote victim empowerment and counseling. The number of professionals with an educational background in the field ranged from 16% to 98%. CONCLUSIONS: The evident disparity across studies shows that some professionals have suboptimal knowledge and require training to adopt the correct attitude when identifying female victims of domestic violence in clinical practice. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered in the Open Science Framework Database under the registration http://doi.org/10.17605/OSF.IO/B7Q6S.

Aim This study aimed to assess the shaping ability of Reciproc Blue in the apical third and apical foramen of moderately curved canals at different working lengths (WLs), by micro-computed tomography. Methods Thirty-six mesial roots (mesiobuccal and mesiolingual canals) were included, each with 2 separate root canals and independent apical foramina, according to type IV of Vertucci’s classification of first and second mandibular molars. The canals were instrumented at three different WLs: G-1, 1mm short of the major apical foramen; G0, at the major apical foramen; G+1, 1mm beyond the major apical foramen. The groups were assessed for changes in root canal volume and untouched wall area in the apical third. Groups G0 and G+1 were also compared for percentage of untouched walls at the apical foramen. One-way ANOVA (post hoc Tukey test) and Student’s t-test adopted a 5% level of significance. Results Root canal volumes (mm3) in the apical third were 22.86±10.46, 44.48±24.91, and 55.71±21.32 in G-1, G0 and G+1, respectively. G-1 volume following instrumentation increased significantly less than that of G0 or G+1 (P>.05); G0 did not differ from G+1. The percentage of untouched wall area in the apical third did not differ among the three groups (P>.05). G0 and G+1 did not differ regarding untouched walls in the major apical foramem walls. Conclusion Extending the WL from 1mm short of the apical foramen to a point at and beyond the WL increases the apical third volume without increasing the prepared area. Untouched surface areas of the apical foramen were not modified by instrumentation at or beyond the foramen.

Necrotic pulp of teeth with open apex leads to challenges in endodontic treatment because the anatomy of the root canal is incompletely formed with widely open apex, root walls thin and fragile and reduced root length. In these situations, four treatment options are available: 1) Apexification with periodic exchanges of intracanal medication (ICM), until radiographic evidence of apical closure; 2) Apexification without exchanges of ICM; 3) Apical barrier using mineral-trioxide-aggregate (MTA) or Biodentine; 4) Pulp revascularization. The endodontist should be attentive to the evolution of treatment techniques and dental materials, with their limitations and directions. This article reviews the literature on the different forms of treatment in cases of traumatized immature teeth, indicating the advantages, disadvantages and limitations of each one.

La necrosis pulpar en dientes con ápice abierto representa un desafio al tratamiento endodóntico. Esto debido a que la anatomía radicular se encuentra parcialmente formada, con ápices abiertos, paredes radiculares finas y frágiles, así como la longitud radicular reducida. En estas situaciones, cuatro opciones de tratamiento están disponibles: 1) Apexificación con renovación periódica de medicación intraconducto (MIC), hasta que sea posible observarradiográficamente el cierre apical; 2) Apexificación sin renovación de MIC; 3) Confección de una barrera apical utilizando agregado de trióxido mineral (MTA) o Biodentine; 4) Revascularización pulpar. El endodoncista debe estar atento a la evolución tanto de las técnicas de tratamiento como de los materiales dentales, conociendo sus indicaciones y limitaciones. Este artículo llevó a cabo una revisión de la literatura sobre las diferentes formas de tratamiento en casos de dientes traumatizados con rizogénesis incompleta y necesidad de tratamiento endodóntico por necrosis pulpar, indicando las ventajas, desventajas y limitaciones de cada una.
