Introduction: The present study aimed to identify the 100 most-cited articles concerning atraumatic restorative treatment (ART) through a bibliometric analysis.
Methods: The search was conducted in the Web of Science database in December 2023. Scopus and Google Scholar were used to compare the number of citations. The following data were extracted from the articles: title, authors, number of citations, access type, institution, country, continent, year of publication, journal, keywords, study design, and theme. Collaborative networks were generated using the VOSviewer software. Google Trends was used to investigate the global popularity of "atraumatic restorative treatment" research.
Results: The 100 selected articles, published between 1996 and 2019, were cited 5,092 times, ranging from 21 to 239 citations. CariesResearch (12%) and Community Dentistry and Oral Epidemiology (12%) published the highest number of articles. Clinical study (52%) was the most prevalent study design. The main theme addressed was restoration longevity (43%). Conventional high-viscosity glass ionomer was the most used restorative material (69%). The country with the highest number of articles was The Netherlands (33%) and Europe was the continent with most publications (38%). The Radboud University of Nijmegen had the highest number of articles (25%). Frencken was the most prominent author (38%). The most common keyword was "atraumatic restorative treatment" (n = 60). According to Google Trends, Tanzania was the country that searched the most about ART.
Conclusion: The 100 most-cited articles on ART were mainly composed of clinical studies focusing on the longevity of restorations and originated in Europe.
Introduction: Dental caries with pulp involvement potentially impacts the oral health-related quality of life (OHRQoL). This meta-analysis aimed to evaluate whether clinical consequences of pulp involvement due to dental caries impacts OHRQoL of children and adolescents.
Methods: Observational studies evaluating whether children/adolescents (population) with pulp involvement due to caries (exposition) compared with those without it (comparison) have more negative impact on their OHRQoL (outcome) were included. A systematic search was undertaken in August 2022 in seven databases. Alerts were set until August 2023. JBI Critical Appraisal tool for cross-sectional studies was used for methodological quality assessment. Random-effects meta-analyses were performed to calculate mean differences (MD) or standardized mean differences (SMD) of impact on OHRQoL. For studies with dichotomous outcome, meta-analysis calculated the odds ratio (OR). Robustness, heterogeneity, certainty of evidence, and publication bias were evaluated.
Results: From 29 included studies, 14 assessed preschoolers, nine assessed schoolchildren, four assessed adolescents, and two assessed children/adolescents. PUFA was the main index used to assess the exposure. ECOHIS (preschoolers) and CPQ (children/adolescents) were the main tools used to assess the outcome. Only five articles fully adhered to the quality criteria. The meta-analyses found the following main results: (a) preschoolers: MD -10.79 (-16.50; -5.09); (b) schoolchildren: MD -5.12 (-7.51; -2.72); (c) adolescents: MD -1.86 (-4.59; 0.87); (d) overall impact: SMD -2.18; (CI: -3.21;-1.15) and OR 0.52 (CI: 0.30; 0.90).
Conclusion: Pulp involvement impacted OHRQoL of children negatively. In adolescents, this impact was not observed. Results must be interpreted with caution due to very low certainty of evidence.
Introduction: There is a correlation between molar incisor hypomineralization (MIH) and hypomineralized second primary molars (HSPM), but this relationship has not been definitively confirmed. The purpose of this systematic review and meta-analysis was to reevaluate whether children with HSPM are more affected by MIH than non-HSPM children.
Methods: A systematic search was conducted in four databases (PubMed, Embase, Web of Science, and the Cochrane Library) for literature, published up to December 2022. Two independent reviewers conducted the study search and screening, quality assessment, and data extraction according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The risk-of-bias assessment of all included cohort studies and case-control studies was assessed by the Newcastle-Ottawa Scale (NOS), and cross-sectional studies were assessed using the Agency for Healthcare Research Quality (AHRQ) scale. RevMan 5.4 software was used for all data analyses, with odds ratios (ORs) and 95% confidence intervals (CIs) as the effect measures. Sensitivity and subgroup analyses were conducted to identify the potential sources of heterogeneity among the studies. Publication bias was tested and corrected by funnel plots and Egger's test. Trial sequential analysis (TSA) was performed using TSA 0.9.5.10 Beta software to control for type-1 and type-2 errors.
Results: A total of 12 studies involving 8,944 children were included in this meta-analysis. Compared with the non-HSPM group, the HSPM group had an increased likelihood of MIH (OR = 10.90, 95% CI = 4.59-25.89, p < 0.05). All the included studies were of moderate-to-high quality. TSA and sensitivity analyses suggested the robustness of this outcome.
Conclusion: This systematic review demonstrated a certain correlation between HSPM and MIH, suggesting that HSPM can play a predictive role in the occurrence of MIH. Further high-quality, multicenter, and large-sample longitudinal studies are highly recommended.
Introduction: Dental sealants applied to occlusal pit-and-fissure surfaces have been shown to prevent caries and arrest occlusal noncavitated carious lesions (NCCLs). The American Dental Association (ADA) recommends that oral healthcare providers apply sealants on occlusal NCCLs. Though the evidence is clear that sealants are effective, few studies have examined the adoption of the ADA guideline by dentists and the duration of protection provided by sealants in a large real-world setting.
Methods: This study used observational electronic health record (EHR) data from a network of dental clinics to follow teeth over a 2 year time period from when they were diagnosed as having an occlusal NCCL until either they were treated with a restoration or the time period ended with no restoration. The objectives of the study were to determine: (1) the degree to which dentists adopted the guideline, (2) whether the duration of protection was different for teeth that received a sealant from teeth that did not receive a sealant, and (3) whether dentists' experience placing sealants was associated with the duration of protection.
Results: Overall, there were 7,299 teeth in the sample. Of those, dentists restored 591 teeth and applied sealants on 164. The sealant application rate for eligible teeth was 2.2%. Sealant application was associated with provider, with 1.9% of providers placing more than half of the sealants. By the end of the observation period, the proportion of teeth progressing to restorations was 8.2% for teeth that had not received a sealant and 3.0% for teeth that had received one (RR = 0.37; 95% CI: 0.16-0.88; p = 0.02). Multilevel survival analysis showed that teeth that had not received a sealant were restored sooner than teeth that had received a sealant (aHR = 0.11; 95% CI: 0.03-0.36; p < 0.01). Overall, teeth that received a sealant had an 89% reduced hazard of restoration within 2 years compared with teeth that did not receive sealants.
Conclusion: This study found that by arresting decay, the presence of sealants led to fewer restorations and delayed restorations compared with teeth not receiving a sealant or restoration in the 2 years following diagnosis of occlusal NCCL in clinical settings.
Introduction: There is little discussion in the literature on the pathway linking oral health problems and academic performance (AP) in children. This study investigated the hypothesis that the influence of dental caries on academic performance is mediated through toothache and impacted sleep and study activities.
Methods: This cross-sectional study on children aged 12-14 years collected data on the exposure (decayed tooth index), outcome (school examination results), and mediator (school absence due to toothache, and oral health impact on sleep and study performances using the Child-Oral Impact on Daily Performance instrument) variables. It used mediation analysis to examine the indirect effects of a single and two serial mediators using model 4 (caries → mediator → AP) and model 6 (caries → mediator 1 → mediator 2 → AP), respectively, in PROCESS macro add-on software in IBM SPSS v24. Analyses were carried out separately for boys and girls at a 5% significance level.
Results: In model 4, school absence due to toothache (boys: 95% CI: 0.42, 1.01; girls: 95% CI: 0.58, 0.98), and impacted sleep (95% CI: 0.13, 0.41; 95% CI: 2.17, 13.03), and study (95% CI: 0.05, 0.42; 95% CI: 0.54, 0.94) performance were significant single mediators in both sexes. In model 6, school absence due to toothache and impacted sleep activity (boys: 95% CI: 0.02, 0.29 and girls: 95% CI: 1.37, 12.81), and school absence due to toothache and impacted study activity (girls: 95% CI: 1.37, 12.81) were significant two serial-mediators.
Conclusion: This study provides empirical evidence showing that dental caries and toothache can impact academic performance as they disrupt sleep and study performances to influence the learning and cognition process. The finding bridges the understanding of the mechanism underpinning the relationship and thus, further emphasizes the importance of caries prevention in children with high caries risk for improving their health outcomes and educational experience.
Introduction: This study aimed to determine the association between residing in municipalities with armed conflict and dental caries among adults in Colombia.
Methods: Data from 9,194 individuals aged 18-79 years, who participated in the Fourth National Oral Health Survey in 2014, were linked with information on the presence and intensity of the armed conflict experienced in their municipality of residence between 2000 and 2012 (extracted from the Resource Centre for Conflicts Analysis). Dental caries was determined through clinical examinations and summarised using the numbers of decayed teeth (DT), decayed and filled teeth (DFT), and decayed, missing, and filled teeth (DMFT). Two-level negative binomial regression models were fitted, with adults nested within municipalities, to test the association between armed conflict indicators and caries outcomes after adjustment for covariates.
Results: The mean DT, DFT, and DMFT scores were 1.75 (SD = 2.36), 6.03 (SD = 4.53), and 10.27 (SD = 7.11), respectively. Of the 197 municipalities included in the analysis, 12.2% experienced conflict permanently and 18.3% experienced high-intensity conflict. In crude analysis, adults living in municipalities with more presence and intensity of armed conflict had lower DT and DMFT, but not DFT scores. After adjustment for covariates, only the (high) intensity of conflict was associated with lower DT (rate ratio: 0.64; 95% confidence interval [CI]: 0.47-0.87), DFT (RR: 0.82; 95% CI: 0.71-0.95), and DMFT scores (RR: 0.81; 95% CI: 0.74-0.89).
Conclusions: This study found that Colombian adults residing in municipalities with high intensity of conflict had lower levels of untreated disease and caries experience.
Introduction: This study investigated the effectiveness of titanium tetrafluoride (TiF4) varnish compared to sodium fluoride (NaF) varnish for preventing and remineralizing white spot lesions (WSLs) in individuals undergoing orthodontic treatment.
Methods: This randomized, placebo-controlled, and double-blinded study was conducted with sixty-five adolescents who were selected based on caries activity and then randomized into three parallel groups: G1 (placebo varnish), G2 (5%-NaF varnish) and G3 (4%-TiF4 varnish). Volunteers received varnish application weekly for the first 4 weeks, after 6 (T1) and 12 (T2) months. The measured outcomes included: prevention of new WSLs, and reversal/progression of WSLs, assessed by Nyvad and ICDAS indices, as well as quantitative light-induced fluorescence (QLF). Chi-square, ANOVA, and Kruskall-Wallis tests were applied. The level of significance was set at 0.05, and post hoc Bonferroni test for p values were performed to correct for multiple comparisons.
Results: 1,274 teeth were included; 70.5% were Nyvad 0, and 29.5% were Nyvad 1, with no differences between the groups at baseline (T0). Regarding ICDAS, 70.5% were ICDAS 0, 21.6% were ICDAS 1, and 7.9% were ICDAS 2. G1 showed an increasing prevalence of WSLs at T1 and maintained stable at T2; G2 exhibited a decline at T2, while G3 experienced a decrease at T1 and T2 (p < 0.01). Incidence of WSLs at T2 was 10.2% (G1), 5.6% (G2) and 1.4% (G3). The percentage of teeth initially scored as Nyvad 0 that progressed to Nyvad 1 was 13%, 6.8%, and 1% for G1, G2, and G3, respectively. Conversely, the percentage of teeth initially scored as Nyvad 1 that regressed to Nyvad 0 or Nyvad 2 (T0-T2) was 14%, 49.3%, and 74.4%, respectively (p < 0.001). As for ICDAS index, regression was observed in 6.5%, 17.8% and 24%, while progression was observed in 14.9%, 7.7% and 0.9% for G1, G2 and G3, respectively (p < 0.001). Significant differences among the 3 groups for integrated fluorescence loss (mean±SD, G1: -14.28±9.47, G2: -11.10±11.49 and G3: -6.77±11.00) were found at T2 (p < 0.01).
Conclusion: Both varnishes demonstrated the ability to prevent and remineralize WSLs. However, TiF4 varnish exhibited the most effective control over WSLs during the 12-month orthodontic treatment.
