OBJECTIVE: Reporting of randomized controlled trials (RCTs) in dentistry remains suboptimal. Considering the positive impact of the Consolidated Standards of Reporting Trials (CONSORT) guidelines on the quality of evidence in RCTs, the main objective of this systematic review was to determine whether RCTs on dental caries prevention conform to these guidelines. The secondary objective was to assess the association between CONSORT adherence and the year and impact factor of the journal in which the study was published. METHODS: A systematic search was conducted in different databases using appropriate terms to retrieve RCTs that assessed the caries-preventive effect of at least 2 of the following materials-fluoride varnish, resin-based fissure sealants, and ionomer-based fissure sealants-on the occlusal surfaces of permanent molars. Since the first CONSORT statement was published in 1996, a time frame from 1997 to 2020 was established for the identification of studies. Selected articles were assessed according to their adherence to the CONSORT statement, risk of bias (Cochrane risk of bias tool, RoB 2.0), and journal impact factor based on the InCites Journal Citation Reports. The year of publication and other relevant data were also recorded. SPSS (SPSS Statistics 25.0, IBM©) was used to perform the linear correlation analyses to determine the relationship between the article CONSORT score (previously determined) and the year of publication and journal impact factor. A significance level of 5% was established for all analyses. RESULTS: Of 3196 references retrieved, 30 articles were selected and evaluated. Using RoB 2.0, 8 studies were classified as having a high risk of bias, 16 as having some concerns about the risk of bias assessment, and 6 as having a low risk of bias. Concerning CONSORT adherence, 77% of the studies adequately reported the intervention domain, since the methodology for the application of fluoride varnish or sealant materials was thoroughly described. However, the participants' setting and location, random sequence generation, randomization, and the flowchart description of the losses/exclusions domains were poorly reported. Meanwhile, the allocation concealment process was not reported in 83% of the articles. Correlation analyses indicated a positive relationship between CONSORT adherence and the year of publication, as well as the journal impact factor. CONCLUSION: When assessing clinical trials on the prevention of occlusal caries, most RCTs examined followed the CONSORT statement. However, some methodological domains remain poorly reported, demonstrating the need to improve CONSORT compliance in these RCTs.

PURPOSE: To analyze the current evidence on the impact of surface finishing protocols (such as manual polishing or glazing) on the color stability of in vitro simulated pigmentation of CAD/CAM ceramics. MATERIALS AND METHODS: Five electronic databases were searched on February 12, 2020. In vitro experimental studies were included based on the following strategy: intervention = surface treatment of CAD/CAM ceramics with glazing agents; comparison = surface treatment of CAD/CAM ceramics with manual polishing; and outcomes = color stability. Two reviewers independently assessed the risk of bias. RESULTS: Among 1,390 articles that were screened, 6 in vitro studies were considered for qualitative analysis. Five articles confirmed changes in the color of ceramics when they were immersed in pigmented solutions. One article investigated the color stability of the samples via ultraviolet (UV) aging. Among the 6 studies analyzed, 4 showed clinically acceptable color alteration values represented by ΔE irrespective of the finishing protocol applied (glazing or mechanical polishing). Two articles presented clinically unsatisfactory color variation (ΔE > 3.3 and ΔE > 2.7) following mechanical polishing of a zirconia-reinforced lithium silicate ceramic. Coffee and red wine proved to be the beverages with the greatest potential for ceramic pigmentation. Only 1 article had a high risk of bias. CONCLUSION: For clinicians, most of the studies demonstrated that both manual polishing and glaze application can prevent significant color alterations on CAD/CAM ceramic surfaces. However, due to the relatively limited amount of evidence to support this conclusion, further studies must be conducted.

OBJECTIVE: To evaluate the accuracy of the near-infrared light transillumination (NILT) for the detection of interproximal dental caries in permanent dentition when compared to bitewing X-ray (BW). DATA: In vivo studies that detected interproximal primary caries in permanent teeth by using NILT and BW were selected. QUADAS-2 was used to assess the risk of bias. Pooled sensitivity and specificity forest plots were calculated, summary receiver operator characteristics (SROC) curves were constructed. The certainty of the evidence was rated using the GRADE system. SOURCES: Pubmed, Cochrane Library, Web of Science, Scopus, Lilacs/BBO and grey literature databases were surveyed. STUDY SELECTION: From 1594 retrieved articles, 13 studies were included. Six studies had a low risk of bias and a low level of concern regarding applicability. Four studies had an unclear risk of bias, while three presented a high risk of bias. The meta-analysis of six studies demonstrated that NILT presented good overall accuracy. Of 6110 teeth, 92.3 % (5639) were accurately classified (776 as true positive and 4863 as true negative). The pooled sensitivity was 0.97 (0.96 to 0.98; p = 0.0000; I2 = 93.2 %) with moderate certainty of evidence, and the pooled specificity was 0.91 (0.91 to 0.92; p = 0.0000; I2 = 98.3 %) with high certainty of evidence. Symmetric (0.9837) and asymmetric (0.9836) SROC showed a high discrimination and determination effect of NILT. CONCLUSION: The current literature, with moderate certainty and a middling quality of evidence, demonstrates that NILT presents a reasonably comparable accuracy to that of BW for detecting interproximal carious lesions in the permanent dentition. CLINICAL SIGNIFICANCE: Since NILT presented good overall accuracy for the detection of interproximal primary caries, it could be routinely used in dental check-ups, especially in high-risk caries populations and in patients where the use of radiation should be reduced, like pregnant women or children.

OBJECTIVE: The aim of this study was to evaluate the morphological and chemical effect of in-office and at-home desensitising agents containing sodium fluoride (NaF) on eroded root dentine in vitro. METHODS: Fifty bovine dentine samples were pre-eroded and randomised into five groups (n = 10): G1 (Control) - milli-Q water; G2 - fluoride varnish containing NaF 22,500 ppm; G3 - desensitising cream containing NaF 9,000 ppm associated with 20% nanohydroxyapatite; G4 - toothpaste with NaF 5,000 ppm associated to tricalcium phosphate; G5 - toothpaste containing NaF 900 ppm and casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF). The specimens were submitted to erosive challenge for three days. The analyses were performed using non-contact profilometry for volumetric (Sa) and linear roughness (Ra) followed by scanning electron microscopy (SEM) and Energy Dispersive X-ray Spectrometry (EDS). The data were analysed by Kruskal-Wallis and Wilcoxon tests (α = 0.05). RESULTS: There was a significant reduction of Ra and Sa for the eroded samples from the G2 and G5 (p < 0.05) after an erosive challenge. The dentine surface topography pattern showed partially or totally occluded dentinal tubules after treatments, except in the control group. The control, G4 and G3 groups showed a reduction in the dentine inorganic content percentage of Ca (Calcium) and P (Phosphorus) minerals. CONCLUSION: The fluoride varnish and CPP-ACPF toothpaste were able to prevent morphological changes and were the only materials that showed the Ca and P content increased after treatment. These materials may be promising alternatives in the clinical control of dentin erosion.
