Background. The purpose of this systematic review was to assess the clinical efficacy (sensitivity reduction) and safety (gum damage) of silver diamine fluoride (SDF) as a tooth desensitizer for adults. Methods. The search strategy was developed and adapted from 12 databases. Two independent reviewers selected the studies in consensus with a third reviewer. Randomized clinical trials with adult volunteers affected by dentin hypersensitivity (DH), and receiving treatment with SDF were included. Studies with volunteers testing tooth whitening products, using some type of desensitizer, or taking analgesic or anti-inflammatory medication were excluded. The risk of bias was assessed according to the RoB 2 tool, and confidence in cumulative evidence, according to GRADE. Results. Only 3 articles were included. The average pain assessed using the visual analog scale was lower in the SDF groups than in the short-term control groups (24h to 7 days) (P = 0.0134 and P = 0.0015) of the two studies. The third study evaluated a combination of SDF and a CO2 laser, compared to using only SDF, and found no statistical difference between the two (P = 0.74). Inflammation and gingival staining were also evaluated in two of the three studies. No adverse effects were reported. All the included studies had a high risk of bias, and the certainty of the evidence was very low. Conclusion. SDF can be used as a safe and effective tooth desensitizer in adults, with good results, as was achieved in a short-term follow-up. However, more studies with longer evaluation periods are required.

Purpose: To compare the antimicrobial effect of treating dentin caries lesions with silver diamine fluoride (SDF) in different concentrations and chlorhexidine (CHX). ]Methods: Children aged 7-10 years presenting one occlusal dentin catious lesion in primary molars were selected, totaling 40 teeth. The sample was randomly divided into four groups: (G 1) 38%-SDF + potassium iodide (KI): (62) 30%-SDF; (63) 2%-CHX; and (64) control group. After cleaning the cavity up to firm dentin, a sample of dentin from the pulp wall was collected; the cavity was then treated with the antimicrobial agent tested and, immediately after, another dentin sample was collected. Cavities were restored with high viscosity glass ionomer cement. Microorganisms were counted, and species from the Streptococcus genus were analyzed for susceptibility to antimicrobial agents. Shapiro-Wilk and Levene's tests were used to assess normality and homogeneity. respectively. Student's t-test, two-way ANOVA, and Bonferroni post-test were applied for multiple comparisons. Results: For the overall microorganisms count, it was observed that Gl and 62 presented a statistically lower number of microorganisms following treatment in comparison to 63 and 64 (P< 0.05). When analyzing the Streptococcus spp. and Enterococcus sp. separately, a statistical reduction in the microorganism count before and after the treatment was observed for all groups (P< 0. 05), excluding the control group. Among the species tested, S. mutans were the least susceptible to SDF treatments compared to the other species. The treatments with SDF were more effective in reducing microorganisms when compared to CHX. Similarly, the susceptibility of Streptococcus to CHX was lower than that observed for SDK.

Objective: To assess the dental caries prevalence with ICDAS II in the mixed dentition, 40 children aged 7 to 11 years old, participating in a social program, whose parents and/or guardians signed a informed consent form. Material and Methods: Clinical examination was carried out after brushing. A single researcher performed the examination and the diagnosis consistency was obtained by Kappa coefficient in 12% of the sample. All dental surfaces were examined receiving a two-digit code. The first one refers to the presence of restoration/sealant and the second, the severity of carious lesions. The data was processed at SPSS software version 10.0 and analyzed using descriptive statistics (absolute distribution, percentage, mean and standard deviation). Results: The coefficient intra-examiner agreement was 0,83. Caries prevalence was considered high because 100% of the children had some surface with non-cavitated caries lesion. ICDAS II can be easily transformed to dmf-s or DMF-S without compromising its integrity. For dmf-s/DMF-S decayed surfaces were considered ICDAS codes 3 to 6, resulting in a dmf-s = 6,57 where 11 children (27,5%) presented no decayed deciduous teeth surface. DMF-S = 2,0 showed that 15 children (37,5%) had none decayed permanent surface, determining a underestimation of the caries disease when using dmf-d/dmf-s and DMF-S indexes. Conclusion: A careful viewing of initial caries lesions makes ICDAS II usefull in evaluating the health promotion actions impact, supporting the planning process, implementation and evaluation of program activities.

Objective: To evaluate the therapeutic decision making for the academic of the last year of dentistry at the universities of the Distrito Federal, on dental caries in deciduous teeth and permanent young. Material and Methods: The evaluation was obtained through the application of a questionnaire containing a diagram representing five different stages of deep carious lesions on interproximal radiographs. Were selected through census of students enrolled last semester of each institution and concluded that the theoretical discipline of pediatric dentistry in accordance with the curriculum offered by the University. Data were analyzed statistically by the chi-square test the 5% level of significance. Results: We analyzed 132 questionnaires of which 30.3% of respondents opted for immediate restorative treatment for the injuries to deciduous teeth in the dentin-enamel junction to the permanent tooth, the percentage rose to 31.1%, revealing that there was similarity between universities about which strategy to use. Regarding caries removal there was a discrepancy in an institution compared the other in choosing the more invasive treatment (p = 0.0014). Conclusion: We see the need to implement teaching strategies for the training of a professional within the philosophy of minimum intervention. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to assess oral microbial colonization before and after the implementation of an oral hygiene protocol in children admitted to a pediatric intensive care unit (PICU) using nonhospitalized healthy children as a control group. Methods: Two groups were analyzed in this clinical study: Group G1 (dentate children admitted to the PICU); and Group G2 (nonhospitalized, healthy, dentate children). The G1 group underwent oral assessments before (G1i) and after (G1f ) a three-day oral hygiene protocol using 0.12 percent chlorhexidine applied at 12-hour intervals. Results: Several pathogenic bacteria were identified in group G1i, which was significantly higher than in group G2 (P<.001). There were significant differences between groups G1i and G1f regarding the presence of pathogenic bacteria (P<.001) and a tongue coat (P<.001). he G1f and G2 groups were comparable concerning the presence of pathogenic bacteria (P=.14). Conclusions: Pathogenic bacteria were present in the oral cavity of almost all hospitalized children and were significantly decreased after an appropriate oral hygiene protocol was incorporated in their daily care. Therefore, regular oral hygiene protocols are warranted in PICUs. [ABSTRACT FROM AUTHOR]
