RESUMO

Purpose: The purpose of this study was to assess the effect of potassium iodide (KI) after applying silver diamine fluoride (SDF) on the staining of demineralized dentin covered or not by a composite resin layer. Methods: Dentin blocks from 30 bovine incisors were demineralized and randomly allocated in three groups (N equals 10): (1) control (no treatment); (2) treated with SDF; and (3) treated with SDF and KI. Half of the specimens of each group received a composite resin restoration immediately after treatment. A colorimetric evaluation, according to the CIE L*a*b* system, was performed at baseline and after seven, 14, 30, and 60 days. The ΔE data were analyzed using the generalized linear model (Δ equals 0.05). Results: The use of KI immediately after applying SDF decreased the dentin staining at all assessment times. SDF treatment only stained the dentin under composite resin after 60 days. The application of KI reduced the dentin under composite resin staining as ΔE values were similar to the control group even after 60 days. Conclusions: The use of potassium iodide minimizes the darkening of dentin and prevents the staining of the dentin under composite resin restorations in the long-term.

RESUMO

The aim of this study was to investigate the influence of shortening of etching time for dentin on the restoration survival after selective carious tissue removal in primary molars. This two-arm randomized clinical trial included sixty-two subjects (5-8 year-old) and 100 primary molars presenting moderate dentin carious lesions on occlusal surface. The sample was randomly assigned into groups previously to adhesive application (Adper Single Bond 2; 3M ESPE): etching time recommended by manufacturer (15 s) or reduced (7 s). Resin composite (Filtek Bulk Fill Posterior Restorative; 3M ESPE) was inserted in a single increment for all restorations. Restorations were evaluated at 1, 6, 12, and 18 months using FDI criteria. Survival estimates for restorations' longevity were evaluated with Kaplan-Meier method. Multivariate Cox regression analysis with shared frailty was used to assess the factors associated with failures (p < 0.05). The etching time did not influence the restorations' survival (HR 0.35 95%CI 0.11-1.12; p = 0.06). Mean estimated time of survival was 17.6 months (95%CI, 17.2-17.9). The survival rates at the 18-month follow-up were 75.7% and 91.4% (AFR: 16.9% and 5.7%) when primary dentin was acid etched for 15 and 7 s, respectively (log-rank p = 0.06). In conclusion, the etching time for dentin did not influence the clinical behavior of adhesives restorations. However, there was a tendency for better clinical outcome when using etching time of 7 s.

RESUMO

Abstract Objective: To investigate the association between child's daytime caring person and risk for higher early childhood caries (ECC) experience. Material and Methods: The sample consisted of all clinical records (census) of children (0-3 years old) attended in a public dental clinic, which contained information about caries experience and child's daytime caring person (mother, grandmother or others). Caries experience was dichotomized as dmft ≤ 2 or dmft >2. Data were analyzed by the chi-square (α = 0.05). Binary logistic regression models were built. Results: From a total of 310 children, 19% of children had the grandmother as daytime caring person. There was no association between child's daytime caring person and caries experience (p=0.32). Logistic regression analysis showed that low daytime caregiver schooling (OR: 5.76 95%CI 1.18-28.18; p=0.02) and child's age (OR: 1.14 95% CI 1.09-1.19; p=0.00) were risk factors, and breastfeeding duration (> 9 months - OR: 0.38 95% CI 0.21-0.68; p=0.00), no nocturnal feeding (OR: 0.50 95% CI 0.27-0.91; p=0.02), and absence of sugar consumption between main meals (OR: 0.50 95% CI 0.28-0.89; p=0.02) were protection factors for ECC. Conclusion: A higher caries experience in early childhood is not associated to child's daytime caring person. On the other hand, the higher caries experience is associated with low caregiver schooling and older children.

RESUMO

BACKGROUND: The authors conducted a systematic review of randomized controlled trials comparing the risk of experiencing restoration failure in primary teeth after complete and selective carious tissue removal of soft dentin. METHODS: The authors searched electronic databases (PubMed [MEDLINE], Scopus, Cochrane Central Register of Controlled Trials) and the ClinicalTrials.gov Web site with manual searching and cross-referencing for trials reporting restoration failure after follow-up of 6 months or longer. Two reviewers independently selected studies, extracted data, and assessed the risk of bias and quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. The authors performed intention-to-treat and per-protocol meta-analyses and calculated odds ratios (OR) as effect estimates in the random-effects model. RESULTS: From 327 potentially eligible studies, the authors selected 23 for full-text screening and included 4. Results showed increased risk of experiencing restoration failure (intention-to-treat analysis, OR [95% confidence interval] 1.74 [1.01 to 3.00], and per-protocol analysis, OR [95% confidence interval] 1.79 [1.04 to 3.09]) after selective carious tissue removal of soft dentin. The risk of bias was high, and the quality of evidence was low. CONCLUSIONS: Selective carious tissue removal of soft dentin may increase the risk of experiencing restoration failure in primary teeth. However, the evidence level is insufficient for definitive conclusions. PRACTICAL IMPLICATIONS: Patients with restorations performed after selective carious tissue removal of soft dentin should have shorter recall visit intervals to evaluate the restorations' quality and control caries disease, allowing for more conservative approaches, such as repair, in cases of defective restorations.

RESUMO

AIM: To assess the undergraduate students' performance in detecting and staging caries and assessing activity using visual inspection. DESIGN: Two independent reviewers searched the literature through PubMed/MEDLINE, Scopus, Lilacs databases, and OpenSINGLE. Meta-analyses summarized the results concerning reproducibility and accuracy at D1 (considering all lesions) and D3 (including only cavitated lesions or lesions into dentin) levels. For activity, we considered sound surfaces plus inactive caries lesions vs active lesions. Meta-regression assessed the effect of methodological variables on the outcomes. RESULTS: Fourteen studies were included. The mean reproducibility values were ≥0.52, except for interexaminer agreement when assessing caries activity (0.39; 95% CI 0.10-0.67). The intra-examiner reproducibility tended to be higher than the interexaminer reproducibility. Overall, undergraduate students' performance in staging caries lesions using visual examination was good (AUC>0.85 and DOR>25). The sensitivity values were moderate; however, these were associated with excellent specificity values. Despite few pooled studies, caries activity assessment revealed moderate overall performance, with lower pooled sensitivity than pooled specificity. Students' education level and background clinical experience had no influence on the accuracy and reproducibility of the visual inspection. CONCLUSION: Undergraduate students' performance in detecting and staging caries using visual inspection was good, although caries activity assessment still requires improvement.

RESUMO

BACKGROUND: Limited data is available on variables influencing the survival of composite restorations in primary teeth. AIM: This retrospective university-based study assessed the survival and risk factors associated with failures of resin composite restorations performed in primary teeth. DESIGN: The sample was composed of 961 restorations from records of 337 patients (178 girls and 159 boys) attended in a university dental clinic. The restorations' longevity up to 48 months of follow-up was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P < 0.05). RESULTS: Mean survival time was 41.5 months (95% CI: 39.7-43.3), with 70.6% of the restorations surviving after 48 months of evaluation. The overall annual failure rate up to 48 months follow-up was 8.3%. Restorations placed in lower arch had lower survival rate than those in upper arch (HR: 1.82, 95% CI: 1.02-3.28). Restorations involving two or more surfaces had more risk of failure than restorations placed in cavities involving only one surface (HR: 2.55 95% CI: 1.34- 4.83). Girls had less risk of failure in their restorations (HR: 0.43, 95% CI: 0.19-0.96). CONCLUSION: Individual and dental variables such as gender, arch type and number of restored surfaces were associated with failure of composite restorations performed in children under daily life clinical environment.

RESUMO

This study aimed to compare the longevity of different conventional restorative materials placed in posterior primary teeth. This systematic review was conducted following the PRISMA statement and registered in PROSPERO (CRD42016035775). A comprehensive electronic search without date or language restrictions was performed in PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, Scopus, Turning Research Into Practice (TRIP) and Clinical Trials databases up to January 2017, selecting randomized clinical trials that assessed the longevity of at least two different conventional restorative materials performed in primary molars. Seventeen studies were included in this systematic review. Pairwise and network meta-analyses were performed and relative risks and 95% confidence intervals (CI) calculated. Two reviewers independently selected the studies, extracted the data, and assessed the risk of bias. Restorations of primary molars with conventional glass ionomer cement showed increased risk of failure than compomer, resin-modified glass ionomer cement, amalgam, and composite resin. Risk of bias was low in most studies (45.38% of all items across studies). Pediatric dentists should avoid conventional glass ionomer cement for restoring primary molars.

RESUMO

This study aimed to systematically review the literature to address the question regarding the influence of different materials in the clinical and radiographic success of indirect pulp treatment in primary teeth. A literature search was carried out for articles published prior to January 2017 in PubMed/MEDLINE, CENTRAL, Scopus, TRIP and ClinicalTrials databases; relevant articles included randomized clinical trials that compared materials used for indirect pulp treatment in primary teeth. Two reviewers independently selected the studies and extracted the data. The effects of each material on the outcome (clinical and radiographic failures) were analyzed using a mixed treatment comparisons meta-analysis. The ranking of treatments according to their probability of being the best choice was also calculated. From 1,088 potentially eligible studies, 11 were selected for full-text analysis, and 4 were included in the meta-analysis. In all papers, calcium hydroxide liner was used as the control group versus an adhesive system, resin-modified glass ionomer cement or placebo. The follow-up period ranged from 24 to 48 months, with dropout rates of 0-25.7%. The material type did not significantly affect the risk of failure of the indirect pulp treatment. However, calcium hydroxide presented a higher probability of failure. In conclusion, there is no scientific evidence showing the superiority of any material used for indirect pulp treatment in primary teeth.

RESUMO

PURPOSE: This clinical retrospective study evaluated the survival and risk factors associated with failures of resin-based composite restorations in primary teeth. METHODS: A total of 212 restorations in primary teeth from records of 76 high caries-risk children were included. The restorations' longevity for up to six years of follow-up was assessed using the Kaplan-Meier survival test. Multivariate Cox regression analysis with shared frailty was used to evaluate the factors associated with failures (P<0.05). RESULTS: Mean survival time was 4.3 years (95 percent confidence interval (CI) equals 4.0 to 4.6). The survival of the restorations reached 35.3 percent, up to the sixth year, with an annual failure rate of 18.8 percent. Restorations placed in teeth with pulp treatment had a lower survival rate than those in vital teeth (hazard ratio [HR] equals 2.16, 95 percent CI equals 1.02 to 4.58). Patients who did not use standard fluoride toothpaste had more risk of failure in their restorations (HR equals 6.12, 95 percent CI equals 1.47 to 25.49). CONCLUSIONS: Composite restorations placed in high caries-risk children presented limited survival after six years of follow-up. Standard fluoride toothpaste use was a protection factor, while pulp treatment was a risk factor for restoration failure.
