title: Oral health of quilombola and non-quilombola rural adolescents: a study of hygiene habits and associated factors

description: Abstract This study evaluated oral hygiene habits and their association with sociocultural, environmental factors and factors related to the use of dental services among Quilombola and non-Quilombola rural adolescents from inland Bahia. Thiswas a cross-sectional study conducted in 2015. Prevalence and prevalence ratios were estimated for the outcomes and multiple Poisson regression analysis with robust variance was performed. We interviewed 390 adolescents, of which 42.8% were Quilombola. Poor tooth brushing and non-flossing were found in 33.3% and 46.7% of adolescents, respectively. Poor tooth brushing was increased by male gender (PR = 1.45), not living with both parents (PR = 1.45), lower hand hygiene habit (PR = 1.72) and worse oral health self-assessment (PR = 1.38). Non-flossing was associated with economic level E (PR = 1.54), older age (PR = 0.91), lower hand hygiene habit (PR = 1.53) and worse oral health self-assessment (PR = 1.33). Different associated factors were observed between Quilombola and non-Quilombola. It is necessary to consider the specificities of the populations for the promotion of adolescent oral health and the importance of the intersectoriality between education and health and care to families.

title: Apical adaptation, sealing ability and push-out bond strength of five root-end filling materials

description: This study compared the fluid filtration, adaptation to the root canal walls, and the push-out bond strength of two resin-based sealers and three calcium silicate-based retrograde filling materials. Fifty maxillary canines were shaped using manual instruments and the apical portion was sectioned. Retrograde cavities of 3-mm depth were prepared. The specimens were divided into five groups (n = 10): Sealer 26 (S26); MBPc (experimental); MTA; Portland cement with 20% zirconium oxide (PC/ZO), and Portland cement with 20% calcium tungstate (PC/CT). The fluid filtration was measured at 7 and 15 days. To evaluate the interfacial adaptation, sections of the teeth, 1 and 2 mm from the apex, were prepared and the percentage of gaps was calculated. The push-out bond strength at 2 mm from the apex was evaluated. Statistical analysis was performed using the ANOVA/Tukey’s test (p &lt; 0.05). At 7 and 15 days (p = 0.0048, p = 0.006), the PC/CT group showed higher fluid filtration values when compared to other groups. At 1 mm from the apex, no statistical differences in the adaptation were found among the cements (p = 0.44). At 2 mm from the apex, the PC/ZO group presented statistically lower percentage of gaps than S26, MBPc, and MTA (p = 0.0007). The MBPc group showed higher push-out bond strength than other cements evaluated (p = 0.0008). The fluid filtration and interfacial adaptation of the calcium silicate-based cements were similar to those of the resin-based cements. The resinous cement MBPc showed superior push-out bond strength.

title: Patient automedication and professional prescription pattern in an urgency service in Brazil

description: Several studies have indicated an increased resistance of microorganisms resulting from the widespread use of antimicrobial agents. However, few data are available in the dental literature. The aim of this study was to conduct a survey on the patterns of patient usage of antimicrobial prescriptions agents by dentists. A retrospective cross-sectional study was based on the medical records of 223 patients who sought treatment at the Urgency Service, from a Dental School in the South of Brazil, from March 2009 to March 2011. A specific data sheet was used, with questions regarding: patient age and gender; the main complaint; medications used prior to the service; final diagnosis; proposed dental treatment (including prescription medications); and characteristics of the final prescription. Descriptive and inferential statistics were obtained. There was a high frequency of antibiotic use prior to attendance by young patients (Fisher’s exact test, p &lt; 0.05). Toothache of endodontic origin was the most frequent patient complaint (72.6%). Endodontic procedures were the measures most frequently adopted to treat the pain (31.2%). The frequency of patient use of antimicrobials prior to the appointment was 14.3%. According to patient records, 83.9% had no systemic drug prescription after receiving urgency treatment. There were few antimicrobial prescriptions after the urgency treatment. The most frequently prescribed agents were amoxicillin, chlorhexidine, and metronidazole. Local measures were more frequently used than systemic approaches to treat urgencies of dental origin. Antimicrobial agents were not frequently prescribed as adjunctives to local administered at the urgency service.

title: Yellow fever in Africa and the Americas: a historical and epidemiological perspective

description: Abstract Yellow fever was transported during the slave trade in the 15th and 16th centuries from Africa to the Americas where the virus encountered favorable ecological conditions that allowed creation of a sustainable sylvatic cycle. Despite effective vector control and immunization programs for nearly a century, yellow fever epidemics reemerged in many Latin American countries, particularly Brazil. The emergence or reemergence of vector-borne diseases encompasses many intricate factors. Yellow fever outbreaks occur if at least three conditions are fulfilled: the introduction of the virus into a non-immune human community, presence of competent and anthropophilic vectors and insufficiency of prevention and/or adequate management of the growing outbreak. On the other hand, two weapons are available to constrain yellow fever: vector control and immunization. In contrast, yellow fever is absent from Asia and the Pacific despite the presence of the vector and the susceptibility of human populations to the virus. Based on a review of the global history of yellow fever and its epidemiology, the authors deliver some recommendations for improving the prevention of epidemics.

title: Using UV light for adhesive remnant removal after debonding of orthodontic accessories

description: Abstract The objective of this study was to assess the effect of a UV light-based auxiliary illumination on adhesive remnant (AR) removal after orthodontic debonding. Sixty human molars were divided according to the adhesive used for bonding: O-opaque; LF-low fluorescence; and HF-high fluorescence. After debonding, the teeth were subdivided according to the AR removal method: No UV light or With UV light. After AR removal, the teeth were polished. Direct visual analysis, scanning electron microscopy (SEM) and time quantification for AR removal analyses were performed (Fisher-Freeman-Halton, Fisher’s exact, chi-square trend, ANOVA, and independent t-tests; α = 5%). Concerning the adhesives, there was no significant difference among direct visual, SEM and time analyses for AR removal (p ≥ 0.05). Regarding AR removal methods, a similarity among the subgroups was verified for direct visual and SEM analyses (p≥0.05). However, a significant trend was verified for the with UV light method to produce greater marks, and the no UV light method, to produce a greater rate of samples with AR before polishing (p = 0.015). AR removal with light was significantly quicker in comparison with the no UV light method (p &lt; 0.0001). The use of UV light may aid orthodontists in removing AR more thoroughly and in less time. However, they should receive special training to apply this technology, and should never dismiss the final polishing procedure.

title: Global burden of disease among teenagers in Uruguay and its comparison with Latin America and the Caribbean

description: Abstract Introduction. Adolescence is considered a healthy stage of life and therefore little studied. This study described mortality over time in teenagers in Uruguay and analysed the burden of disease at this stage of life by the measure of Years of Life Lost by Premature Death in Uruguay and by comparison with rates in Latin America and the Caribbean by sex, cause and sub-region. Methodology. Secondary data sources used were the national registry of deaths in Uruguay, the first Global Burden of Disease study in Uruguay and the information on the data visualisation page of the Institute of Metrics and Health Evaluation. Data were extracted by the authors and displayed in tables and graphs. Results. Teenager mortality held roughly stable between 1997 and 2015. More years were lost to premature death among Uruguayan men, the main causes being traffic accidents, self-inflicted injuries and violence. The same behaviour occurs throughout the region. Conclusions. The social determinants of health connected with poverty and inequality play a role in the development of depression, risky and violent behaviour, which possibly explain the loss of years due to premature death in adolescence.

title: Successful multiple-exchange peritoneal dialysis in a patient with severe hematological toxicity by methotrexate: case report and literature review

description: Abstract Methotrexate is an effective medication to control several diseases; however, it can be very toxic, being myelosuppression one of its main adverse effects, which increases in severity and frequency in patients with renal failure. We present the case of a 68-year-old man with chronic, end-stage renal disease associated with ANCA vasculitis, under treatment with peritoneal dialysis, who received the medication at a low dose, indicated by disease activity, which presented as a complication with severe pancytopenia with mucositis that improved with support measures and multiple-exchange peritoneal dialysis. We reviewed 20 cases published to date of pancytopenia associated with methotrexate in patients on dialysis and found high morbidity and mortality, which is why its use in this type of patient is not recommended. However, when this complication occurs, a therapeutic option could be the use of multiple-exchange peritoneal dialysis in addition to supportive therapy for drug-related toxicity, although it is recognized that studies are required to show the role of multiple-exchange peritoneal dialysis in the removal of this medication.

title: Effects of different drying methods on the bioactive compounds and antioxidant properties of edible Centaurea (Centaurea cyanus) petals

description: Abstract The present study aimed to evaluate the effects of hot-air convective drying, shade drying and freeze-drying on the bioactive compounds and antioxidant activity of Centaurea ( Centaurea cyanus L.) petals, as well as on several of their physicochemical properties. All the dried samples showed different appearances as compared to fresh petals, with lower titratable acidity, lower carotenoids and hydrolysable tannins contents, and greater antioxidant activity. Of the drying methods, shade drying presented the highest values for monomeric anthocyanins, flavonoids, hydrolysable tannins, total reducing capacity and antioxidant activity. By contrast, greater losses were observed as a result of hot-air convective drying. Thus shade drying is a highly promising process that should be considered as a suitable drying method for Centaurea petals.

title: Ethical proceedings against dentists in Espírito Santo for infringements to the code of dental ethics

description: Just like any other profession, dentistry requires ethical and moral responsibilities that must be fulfilled, and the duty of every professional is to meet his obligations under the law. In light of the Código de Ética Odontológica (CEO - Code of Dental Ethics), this research aims to expound on the ethical violations committed by dentists in their practice, according to the ethical review process proposed by the Conselho Regional de Odontologia do Estado do Espírito Santo (CRO/ES - Regional Council of Dentistry of the State of Espírito Santo). The study is both retrospective and descriptive, using a quantitative approach. Data collection comprised all the ethical proceedings filed at the CRO/ES, between the years 2000 and 2011. Considering the 529 cases examined, the most frequent reason for infringement was illicit advertising (39.7%), followed by technical error (18.7%), irregular registration (16.8%), patient/professional relationship (11.3%) tax lien foreclosure (6.6%), professional/professional relationship (4.0%), irregular/illegal cover up practice (0.9%), consumer relations (0.8%), failure to provide care (0.6%), false certification (0.4%), and disrespect for authority and colleagues (0.2%). Most (59.2%) of the dental surgeons (DSs) involved were male, 35.5% were between 31 and 40 years of age, 85.8% had graduated over five (5) years prior, and 73.2% were general practitioners. Only 22 (4.2%) cases went to trial, resulting in 8 (36.4%) acquittals and 14 (63.6%) convictions. The most commonly applied penalties were private warning + pecuniary penalty (8 or 57.1%). It was concluded that the CEO must be followed with more discipline, and that professionals should seek information about their duties and obligations under the law, on behalf of patient welfare.
