title: COVID-19 pandemic impacts to Dentistry

description: ABSTRACT Objective: To achieve a literature review on the impacts of COVID-19 on dentistry. Methods: Analysis of scientific articles contained in the LILACS and PubMed platforms that fulfill the informative purpose of the research. Results: The production of aerosols during dental procedures could be highlighted as the most dangerous agent, the literature recommends restricting the type of service only to emergencies and reducing the use of rotating instruments or cough-inducing equipaments. New protective measures must be taken, such as the type of PPE used and the frequency of asepsis of the workplace, since any surface that has been exposed to oral or pharyngeal secretions may contain a load of viral particles, an online triage is also recommended before any assistance. Due to the easy spreading of this disease and the possibility of asymptomatic patients, the current best measure is avoiding the execution of procediments. Conclusion: COVID-19 will be a milestone for the current generations of health professionals, it could also be an advance for use distance technologies and integration of new biosafety techniques.

title: Can Mental Index be used on CBCT images to determine sexual dimorphism?

description: ABSTRACT Objective: Radiomorphometric indices (RI) vary according to gender and age. The objective of this study was to assess bone quality in men and women, using tomographic images Methods: A total of 78 Cone Beam Computed Tomography (CBCT) images of female and male patients were analyzed. The images were obtained from LAPI-FOUSP database, São Paulo, Brazil, and the Mental Index, which is a quantitative index, was evaluated on those images. The images were divided into 2 groups: Group M – Men and Group W – Women and evaluated by one examiner in two different times (T1 and T2). The data was submitted to a statistical analysis with a 95% level of significance (p &lt;0.05) Results: The ICC tests showed an average to good intra-examiner agreement. The age averages were: 48.46 ± 15.3 for group W and 53.87 ± 13.09 for group M. On the MI evaluation, statistically significant differences were observed between the two groups Conclusion: We concluded that MI can be used to determine sexual dimorphism, once the thickness of the mandible cortex in women is smaller than the thickness found in men.

title: Surgical complications in systemically compromised patients: analysis of 992 medical records

description: ABSTRACT Objective: The preoperative evaluation is essential to prevent postoperative surgical complications. The present study aimed to establish quantitative and qualitative profiles of systemic disorders and relate them to postoperative surgical complications in patients subjected to dental extraction Methods: Data were collected from the medical records of 992 patients subjected to dental extractions from 2010 to 2015 through a detailed analysis of anamnesis files. The data collected were tabulated and converted to percentages to facilitate the discussion and comparison with reports in the literature Results: From all the medical records analyzed, 559 presented systemic changes, which corresponds to 56.3%. Among them, there was a higher prevalence of patients with hypertension (24%), smoking habits (20%), and diabetes (11%). The most frequent complications were pain (34%), inflammation (19.8%), and hemorrhage (13.2%). The prevalence of diseases related to age shows patients under the age of 20 (4.7%), 20 to 29 (11.3%), 30 to 39 (16.8%), 40 to 44 (10%), 45 to 49 (10.9%), 50 to 54 (12.3%), 55 to 59 (12.9%), 60 to 64 (10.4%), 65 to 69 (4.8%), and older than 70 years old (5.9%). As for systemic changes with complications, hypertensive patients with complications (n=11) showed higher prevalence of pain (45.4%), the most common complication in smokers (n=15) was exacerbated inflammation (33.3%), and 50% of diabetic patients with complications (n=8) were diagnosed with alveolitis Conclusion: The method studied allowed concluding there was a relationship between postoperative complications and systemic changes, and the main ones were pain-hypertension, inflammation-smoking, and alveolitis-diabetes.

title: Effect of music on reducing anxiety in children during dental treatment

description: ABSTRACT Objective: The objective of this study was to evaluate the impact of music on anxiety in children during dental care Methods: A total of 40 children 5 to 11 years old were selected; they were randomized into 2 groups (n = 20): group 1: experimental, children were subjected to music therapy; group 2: control, children were not subjected to music therapy. We measured oxygen saturation, heart rate and levels of Corah anxiety scale and pain scale. The results for heart rate were evaluated by ANOVA. The Kruskal Wallis (Dunn) test was used to evaluate the oxygen saturation results and the Wilcoxon test for Corah anxiety and pain scores Results: There was a significant decrease in heart rate (pulse) in children who listened to music during dental treatment (p = 0.05). In the group without music, heart rate remained unchanged throughout the care (p = 0.53). There was no significant difference in oxygen saturation or Corah anxiety and pain scores in children who listened to music during dental care (p &gt; 0.05) Conclusion: It can be concluded that music is a non-pharmacological alternative that reduces anxiety levels in children during dental treatment.

title: Availability and stability of soluble fluoride content in commercial fluoride dentifrices available in Uruguay

description: ABSTRACT Objective The aim of this study was to evaluate the availability and stability of soluble fluoride fraction in commercial fluoride toothpastes available in Uruguay. Methods Fourteen fluoride toothpastes from four different manufacturers were analyzed. Randomized and blinded analyses were performed in duplicate for each dentifrice at the time of purchase (fresh samples) and after 12 months of storage at room temperature (aged samples). Total fluoride and total soluble fluoride concentrations were measured using a fluoride specific electrode. Results Total fluoride concentrations in all of the products were lower than the F levels specified by the manufacturers. Total soluble fluoride fractions were lower than the total fluoride concentrations in fresh samples of five toothpastes and in aged samples of ten toothpastes (p &lt; 0.05). Three toothpastes had insufficient and unstable total soluble fluoride fractions (&lt; 60%) and five toothpastes had only unstable total soluble fluoride fractions (&lt;1000 ppm) after 12 months. Conclusion Based on theresults of this study, it can be concluded that from fourteen Uruguayan commercial fluoride toothpastes analyzed in this study, three toothpastes have insufficient and unstable chemically active F fractions and five other toothpastes have the lack of stability which may compromise their efficacies. Review the guidelines on fluoride dentifrices in Uruguay is necessary, in order to ensure optimum benefit for population.

title: Qualitative and quantitative analysis of Mercury ions on the surface of amalgam restorations after home bleaching

description: ABSTRACT Objective The bleaching agents may interact with restorative materials, such as dental amalgam, providing an increase mercury ions (Hg) release, whose toxic effect is known. Whereas many patients have amalgam restorations (AR) and seek bleaching treatments, the present study aimed to evaluate in vitro the amount of Hg released from AR made with spherical alloy, after being subjected to different concentrations of carbamide peroxide (CP) for home bleaching. Methods 40 class I AR were prepared in bovine teeth. Afterthe restoration, the samples were randomly allocated into 4 groups (n = 10): C (control group), CP10 (CP 10%) CP15 (CP 15%) CP20 (CP 20%) and its treatments were simulated for 14 days for 6 hours daily. The Hg ions released was measured by energy dispersive X-ray spectroscopy (EDS) and surface changes were assessed in the Scanning Electron Microscope (SEM). Hg levels (percent mass) were recorded and the differences were statistically analyzed using the Kruskal-Wallis test and Dunn’s “Post hoc” test. Results Statisticalanalysis showed the bleaching treatment resulted in a higher Hg release (p &lt;0.05), although no visible changes were identified in micrographs when comparing the control group with the other groups (CP10, CP15, CP20). Conclusion Increased Hg release may be observed during simulated home bleaching.

title: Influence of ibuprofen-arginine on the concentration of amoxicillin in the plasma and tissues of rats with induced periapical lesion

description: ABSTRACT Objective The aim of this study was to evaluate the influence of ibuprofen-arginine on the concentration of amoxycillin in the plasma and periapical tissues of rats with induced apical periodontitis. Methods Twenty-eight Wistar rats were divided into the following four groups: PL: placebo (saline); AM: amoxycillin (100 mg/kg); IB: ibuprofen-arginine (100 mg/kg); and AM+IB: amoxycillin (100 mg/kg) + ibuprofen-arginine (100 mg/kg). The animals were submitted to pulp exposure in the first lower left molar, which remained open for fifteen days; this was then closed with composite resin and remained for a further seven days. The treatments were performed using a single dose of the medication (gavage) one hour before taking the samples. Two mL of blood was collected from the aorta to obtain the blood plasma and the periapical tissue samples, which were homogenized to obtain the supernatant. The samples (plasma and the supernatant periapical tissue) were used to obtain the antibiogram for the analysis of the levels of amoxycillin in the plasma and periapical tissues. Results The amoxycillin concentration was higher in the AM group compared to the other groups (p &lt; 0.05, ANOVA with Tukey’s test). Ibuprofen-arginine interfered with plasma concentration of amoxycillin; however, the AM+IB group had a higher concentration of amoxycillin than the PL and IB groups (p &lt; 0.05, ANOVA with Tukey’s test). The analysis of the supernatant from the periapical tissues showed no significant difference between the groups (p &gt; 0.05, Kruskal-Wallis test). Conclusion Ibuprofenarginine can interfere with the plasma concentration of amoxycillin but this study failed to show the effect of ibuprofen-arginine on the concentration of amoxycillin in the periapical tissues .

title: Behavior and reaction of children to dental care, when submitted to play workshops before and after treatment

description: ABSTRACT Objective Strategies to prepare the child with play activities in order to establish an initial friendly relationship between patient and dentist are widely used as a means to soften the inconsistent behaviors and negative emotions during dental treatment. Thus, the objectives of this study were to evaluate the emotions of children before and after performing play activities and at the end of dental treatment, as well as assessing child behavior. Methods A total of 74 children, both boys and girls, aged 4 to 10 years old, participated in this study and attended the Pediatric Dentistry Clinic for two consecutive semesters. The children responded as they felt through the Emotions Deck during the three stages. In addition, data on behavior and procedures were also collected. Results A total of 468 emotions were evaluated, of which 69 (14.75%) were negative and 399 (85.25%) were positive; the joy was the one of greater frequency in the three evaluated moments. A total of 128 (82.05%) positive emotions were observed before, 133 (85.25%) after the play activities and 136 (87.18%) of the positive emotions were after the dental treatment. As for negative emotions, 28 (17.94%) were before, 23 (14.74%) after play activities and 20 (12.82%) after treatment. Regarding behavior, only 9 (5.77%) were not registered as cooperative, while 147 collaborated (94.23%). Conclusion Therefore, it was possible to conclude that the majority of the patients presented positive emotions at the different moments evaluated and the negative emotions were observed mainly before the ludic activities, having a reduction after the dental care. Most patients demonstrated cooperative behavior.
