Abstract
BACKGROUND There is an increasing proportion of older people in the population worldwide, with a large group being dependent on the care of others. Dependent older people are more vulnerable to oral diseases, which can heavily impact their quality of life (OHRQoL) and general health. OBJECTIVE The purpose of this systematic review was to comprehensively assess interventions to improve oral health or guarantee access and adherence to dental treatment of dependent older people. METHODS We searched MEDLINE, EMBASE, CENTRAL and clinical trial registries. Two reviewers performed the selection, data extraction, risk of bias evaluation using the Cochrane Risk of Bias tool and assessment of certainty of the evidence. When possible, we conducted a meta-analysis to calculate effect estimates and their 95%CIs. Primary outcomes were OHRQoL, oral/dental health, and use of the oral care system. RESULTS We included a total of 30 randomised clinical trials assessing educational and non-educational interventions for community-dwelling older people (n = 2) and those residing in long-term care facilities (n = 28). Most studies assessed oral hygiene and showed that interventions may result in a reduction in dental plaque in the short term (with low certainty of evidence), but there is limited evidence for long-term effectiveness. Only one study assessed OHRQoL, and none evaluated changes in the use of the oral health care system. CONCLUSION Our findings do not provide strong conclusions in favour of any specific intervention, mainly due to study quality and imprecision. There is limited information about the long-term effect of interventions, and further research is needed, especially targeting community-dwelling older people. PROSPERO ID CRD42021231721.

Bioengineering (Basel) 2024; 11:465. [PMID: 38790332 PMCID: PMC11117797 DOI: 10.3390/bioengineering11050465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2024] [Revised: 05/03/2024] [Accepted: 05/03/2024] [Indexed: 05/26/2024] Open
Abstract
The application of calcium coacervates (CCs) may hold promise for dental hard tissue remineralization. The aim of this study was to evaluate the effect of the infiltration of artificial enamel lesions with a CC and its single components including polyacrylic acid (PAA) compared to that of the self-assembling peptide P11-4 in a pH-cycling (pHC) model. Enamel specimens were prepared from bovine incisors, partly varnished, and stored in demineralizing solution (DS; pH 4.95; 17 d) to create two enamel lesions per sample. The specimens were randomly allocated to six groups (n = 15). While one lesion per specimen served as the no-treatment control (NTC), another lesion (treatment, T) was etched (H3PO4, 5 s), air-dried and subsequently infiltrated for 10 min with either a CC (10 mg/mL PAA, 50 mM CaCl2 (Ca) and 1 M K2HPO4 (PO4)) (groups CC and CC + DS) or its components PAA, Ca or PO4. As a commercial control, the self-assembling peptide P11-4 (CurodontTM Repair, Credentis, Switzerland) was tested. The specimens were cut perpendicularly to the lesions, with half serving as the baseline (BL) while the other half was exposed to either a demineralization solution for 20 d (pH 4.95; group CC + DS) or pHC for 28 d (pH 4.95, 3 h; pH 7, 21 h; all five of the other groups). The difference in integrated mineral loss between the lesions at BL and after the DS or pHC, respectively, was analyzed using transversal microradiography (ΔΔZ = ΔZpHC - ΔZbaseline). Compared to the NTC, the mineral gain in the T group was significantly higher in the CC + DS, CC and PAA (p < 0.05, Wilcoxon). In all of the other groups, no significant differences between treated and untreated lesions were detected (p > 0.05). Infiltration with the CC and PAA resulted in a consistent mineral gain throughout the lesion body. The CC as well as its component PAA alone promoted the remineralization of artificial caries lesions in the tested pHC model. Infiltration with PAA further resulted in mineral gain in deeper areas of the lesion body.

Abstract
Background and Objectives: The therapeutic management of carious lesions remains a significant focus for researchers, given their persistently high prevalence despite being largely preventable. This study aimed to compare the effectiveness of a composite resin-based sealant material in halting extended non-cavitated dentin carious lesions when used therapeutically versus preventively on caries-free teeth over a period of twelve months. Materials and Methods: out of the 236 children examined, 45 were excluded from the study due to non-compliance with the inclusion criteria. Thus, the study included 191 children aged 10-12 years, and 764 molars in total. Results: among these molars, 171 were caries-free (ICDAS II code 0), forming the Control group, while 180 molars were classified with an ICDAS II score of 3, forming the Study group. All molars were sealed and evaluated at 6- and 12-month follow-up intervals. Both intervals revealed statistically significant differences (p < 0.05) in sealant retention and carious lesion development between sound (ICDAS code 0) and decayed (ICDAS code 3) teeth. Conclusions: the findings did not support the effectiveness of sealants in halting non-cavitated dentin carious lesions classified as ICDAS II with code 3 compared to their preventive application in sound teeth classified as ICDAS II with code 0.

Abstract
BACKGROUND The aim of this research was to compare the efficacy of the remineralising potential of self-assembling peptides (SAPs): Curodont Repair (P11-4), P26, and leucine-rich amelogenin peptides (LRAP) with the standard 5% NaF varnish (Duraphat) on early enamel caries lesions (EECLs). METHODS A demineralising solution (DS) was used to create artificial EECLs in human dental enamel specimens, which were randomly allocated to treatment groups: P11-4; P26 solution; LRAP solution; 5% NaF varnish; and deionised water (DIW). Each specimen was subjected to 8 days of pH cycling. Specimens from each test group were subjected to microcomputed tomography (micro-CT) and nanomechanical testing to assess mineral density (MD), hardness (H), and elastic modulus (EM) properties of sound, demineralised, and treated enamel. RESULTS The mean MD percentage gain was highest in the P26 and P11-4 groups, followed by the LRAP, 5% NaF varnish, and DIW groups. There were statistically significant differences amongst groups. In the outer layer of EECLs, the EM and H were highest in P26 and P11-4 groups, followed by the LRAP and 5% NaF varnish. In the inner layer of EECLs, the EM and H were highest in P11-4 and P26 groups, indicative of enhanced penetration and remineralisation of the deeper parts of the artificial EECLs. CONCLUSIONS P26 and P11-4 SAPs are more effective than 5% NaF varnish in remineralising the depth of EECLs.

Preventive management of carious lesions: from non-invasive to micro-invasive operative interventions. Br Dent J 2024; 236:603-610.

Abstract
Understanding that dental carious lesions occur as a result of the action of micro-organisms in the dental plaque biofilm, where demineralisation on the tooth surface is the first sign of the disease, such incipient lesions can be treated using preventive, non-operative and minimally invasive operative dentistry. If the caries process is left unmanaged, the lesions progress towards cavitation, leading to more invasive treatments. This article discusses the principles of preventive, non-invasive and micro-invasive treatments of early carious lesions, outlining the clinical situations where these therapies can be applied.

[PMID: 38515110 PMCID: PMC10958835 DOI: 10.1186/s12903-024-04011-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Accepted: 02/11/2024] [Indexed: 03/23/2024] Open
Abstract
BACKGROUND Treating white spot lesions (WSLs) with resin infiltration alone may not be sufficient, raising questions about its compatibility with other treatments amid controversial or incomplete data. Therefore, this study aimed to assess the aesthetic feasibility of resin infiltration combined with bleaching, as well as its potential mechanical effect on ceramic bonding to WSLs. METHODS One hundred and fifty flat enamel surfaces of bovine incisors were prepared. Ninety specimens were deminerailized and randomly assigned to three groups(n = 30): post-bleaching resin infiltration (Bl-R), pre-bleaching resin infiltration (R-Bl), and only resin infiltration (R). Color, surface roughness and microhardness were assessed in immediate, thermocycling and pigmentation tests. The remaining sixty samples were randomly assigned to three groups (n = 20): control (Ctrl), bonding (Bo), pre-bonding resin infiltration (R-Bo). Shear bonding strength, failure mode, micro-leakage depth and interface morphology were evaluated after ceramic bonding. The Tukey test and analysis of variance (ANOVA) were used for statistical analysis. RESULTS For the effect of resin infiltration and bleaching on WSLs, the R-Bl group showed the worst chromic masking ability, with the highest |ΔL|, |Δa|, |Δb|, and ΔE values after treatment. Compared with those in the Bl-R group, the R-Bl and R groups showed significant time-dependent staining, which is possibly attributed to their surface roughness. For the effect of resin infiltration on the adhesive properties of WSLs, resin infiltration reduced the staining penetration depth of WSLs from 2393.54 ± 1118.86 μm to 188.46 ± 89.96 μm (P < 0.05) while reducing WSLs porosity in SEM observation. CONCLUSIONS Post-bleaching resin infiltration proved to be advantageous in the aesthetic treatment of WSLs. Resin infiltration did not compromise bonding strength but it did reduce microleakage and enhance marginal sealing. Overall, resin infiltration can effectively enhance the chromatic results of treated WSLs and prevent long-term bonding failure between ceramics and enamel. Based on these findings, the use of post-bleaching resin infiltration is recommended, and resin infiltration before ceramic bonding is deemed viable in clinical practice.

FRONTIERS IN ORAL HEALTH 2024; 5:1332298. [PMID: 38496333 PMCID: PMC10940413 DOI: 10.3389/froh.2024.1332298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 01/24/2024] [Indexed: 03/19/2024] Open
Abstract
Introduction Silver Diammine Fluoride (SDF) is a clinically used topical agent to arrest dental caries. However, the kinetics of its chemical interactions with hydroxyapatite (HA), the principal inorganic component of dental enamel, are not known. The aim was to characterize the step-wise chemical interactions between SDF and HA powder during the clinically important process of remineralization. Methods Two grams of HA powder were immersed in 10 ml acetic acid pH = 4.0 for 2 h to mimic carious demineralization. The powder was then washed and dried for 24 h and mixed with 1.5 ml SDF (Riva Star) for 1 min. The treated powder was then air-dried for 3 min, and 0.2 g was removed and stored in individual tubes each containing 10 ml remineralizing solution. Powder was taken from each tube at various times of exposure to remineralization solution (0 min, 10 min, 2 h, 4 h, 8 h, 24 h, and 10 days), and characterized using Magic Angle Spinning-Nuclear Magnetic Resonance (MAS-NMR) spectroscopy. Results and discussion 19F MAS-NMR spectra showed that calcium fluoride (CaF2) started to form almost immediately after HA was in contact with SDF. After 24 h, the peak shifted to -104.5 ppm suggesting that fluoride substituted hydroxyapatite (FSHA) was formed with time at the expense of CaF2. The 31P MAS-NMR spectra showed a single peak at 2.7 ppm at all time points showing that the only phosphate species present was crystalline apatite. The 35Cl MAS-NMR spectra showed formation of silver chloride (AgCl) at 24 h. It was observed that after the scan, the whitish HA powder changed to black color. In conclusion, this time sequence study showed that under remineralization conditions, SDF initially reacted with HA to form CaF2 which is then transformed to FSHA over time. In the presence of chloride, AgCl is formed which is subsequently photo-reduced to black metallic silver.

Abstract
OBJECTIVE There are currently no integrated data on the trend of dental caries amongst distinct age groups in Iran. We aimed to assess the national and subnational trend of dental caries of permanent teeth in Iran from 1990 to 2017. METHODS A literature search about dental caries and the decayed-missing-filled teeth index (DMFT) was performed in PubMed, Web of Science, Scopus, and 3 national databases (in Persian). All eligible national oral health surveys in these 28 years were included. We categorised and aggregated the DMFT values and their components based on age (5-year-based groups from 5 to 9 to 60+ years), sex, year, and province. The data for missing spots were estimated using the spatiotemporal Bayesian hierarchical model. We used the bootstrap method in multilevel models to predict the uncertainty interval (UI) of the modelled results. RESULTS Nationally, the all-ages mean DMFT increased by nearly 58.0% (6.8 [95% UI, 4.1-10.5] in 1990 to 10.8 [95% UI, 7.5-14.5] in 2017). Decayed teeth (DT) and missing teeth (MT) rose by 84.5% and 31.6% during this period, respectively. Filled teeth (FT) showed almost a 2.6-fold increase in the same period from 0.6 (95% UI, 0.01-1.6) in 1990 to 1.7 (95% UI, 0.6-2.8) in 2017. The proportion of DT and FT continuously increased in both sexes. In 2017, the highest DT, MT, and FT were estimated in the 25-29 (4.9 [95% UI, 2.5-7.2]), 60+ (21.5 [95% UI, 17.5-25.4]), and 35-39 (2.6 [95% UI, 1.3-4.0]) year age groups. CONCLUSIONS Caries of permanent dentition levies a growing burden on the Iranian population. Considering the continuous increase in caries during the 1990-2017 period, Iranian policymakers should pay heed to these findings and react more proactively to mitigate this perpetuating issue. Implementing nationwide interventions such as sugar consumption management should be encouraged to achieve sustainable outcomes in this regards.

Clinical Investigation of the Inhibitory Effects of Tooth-Coating Materials on Initial Active Root Caries: A Pilot Randomized Controlled Trial. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:150. [PMID: 38256410 PMCID: PMC10820091 DOI: 10.3390/medicina60010150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 01/08/2024] [Accepted: 01/11/2024] [Indexed: 01/24/2024]
Abstract
Background and Objectives: Caredyne ZIF-C is a novel, capsule-mixed zinc-containing prototype glass ionomer cement (GIC). Zinc ions are reported to inhibit root dentin demineralization, dentin collagen degradation, bacterial growth, acid production, and in vitro bacterial biofilm formation. However, the effectiveness of GICs against initial root caries lesions is unclear. Therefore, this study aimed to evaluate the efficacy of GICs, especially the new zinc-containing Caredyne ZIF-C GIC, as tooth-coating materials in patients with initial active root caries. Materials and Methods: A total of 58 lesions in 47 older adults (age > 65 years) were randomly allocated to one of the following three groups: Caredyne ZIF-C, Fuji VII (a conventional GIC), and sodium fluoride (NaF). All the lesions were treated with the assigned materials without removing the infected dentin, and the rates of dental plaque attachment and coating material fall-out were evaluated after 3, 6, and 12 months. The failure rate was defined as the number of teeth that needed restoration due to caries progression. Results: The plaque attachment rates tended to be lower in the material-coated root surfaces than in the healthy exposed root surfaces after 3, 6, and 12 months, although the differences among the three groups were not significant. Moreover, the coating material fall-out rate tended to be lower in the Caredyne ZIF-C group than in the Fuji VII group. There was no significant difference in the failure rate among the three groups at the 12 months mark. Conclusions: Though this pilot study offers a new direction for suppressing the progression of initial active root caries by controlling plaque attachment using GICs including Caredyne ZIF-C, clinical studies with a larger sample size are needed.

Abstract
Background and Objectives: Dental caries is still a dramatic public health problem. The effectiveness of an alternative technique using acidulated phosphate fluoride (APF) gel pH 3.5 was evaluated and compared with conventional treatments in reducing dental caries incidence. Materials and Methods: A double-blind randomized controlled trial was conducted, involving 180 children aged 4-11 years. Three groups were formed: NaF varnish (NaFV), APF in tray (APFt), and APF in toothbrush (APFtbru). Clinical examinations were performed using standardized criteria and the ICDAS Index was assessed. The Caries Treatment Needs Index (CTNI) was calculated. Dental examinations were conducted at baseline, 12 months, and 24 months. Results: At baseline, 16,719 dental surfaces were included, with 15,434 surfaces being sound. After 24 months, the Kaplan-Meier analysis showed significant differences between the APFtbru group and the other two groups (p = 0.03). Cox regression analysis revealed that the surfaces treated with NaF varnish had the lowest survival rates (HR = 0.51 95%CI = 0.33/0.81). Occlusal surfaces had the lowest cumulative survival, while other tooth surfaces showed similar performance. Conclusions: The alternative technique of APF gel application with a toothbrush resulted in maintaining dental health over 24 months. This technique can be cost-effective and may offer advantages over traditional fluoride varnish application.

Comparative effect of different patient education modalities on quality of life in breast cancer survivors: A systematic review and network meta-analysis. Eur J Oncol Nurs 2023; 67:102411. [PMID: 37806151 DOI: 10.1016/j.ejon.2023.102411] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/20/2023] [Accepted: 09/07/2023] [Indexed: 10/10/2023]
Abstract
PURPOSE To assess the comparative effect of patient education modalities (online, telephonic, mixed, in-person meetings) on the improvement of quality-of-life in breast cancer survivors. METHODS A search was conducted in different databases, being only included randomised controlled trials. The methodological quality and the risk of bias were assessed following the criteria of PEDro and Cochrane Rob-2 tools, respectively. The certainty of the evidence was judged using the GRADE tool. These evaluations were performed by two independent reviewers. When possible, data was pooled in a network meta-analysis (95% confidence interval [CI]). RESULTS Fourteen studies were included in the qualitative synthesis (1632 participants) and 11 in the quantitative (1482 participants). Network comparisons revealed that mixed educational modality was the highest ranked intervention at short (MD = 0.62; 95% CI [-0.35, 1.6]) and long -term (MD = 1.1; 95% CI [-1.5, 3.8); the control condition was the last in both cases, with a good convergence of the model observed. However, comparisons did not show significant differences. CONCLUSIONS Health policies could benefit from mixed modalities of patient education as it is expected to generate socio-economical savings and promote patient self-management. Probably, online mixed modalities, i.e. virtual face to face meetings, could be a more up-to-date option that fit best to nowadays patients' lifestyle. However, the limitations of this review force us to interpret our results with caution.

Abstract
OBJECTIVES To describe how systematic reviews with network meta-analyses (NMAs) that used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) NMA approach addressed intransitivity when assessing certainty of evidence. DESIGN Systematic survey. DATA SOURCES Medline, Embase and Cochrane Database of Systematic Reviews from September 2014 to October 2022. ELIGIBILITY CRITERIA Systematic reviews of randomised controlled trials with aggregate data NMAs that used the GRADE NMA approach for assessing certainty of evidence. DATA EXTRACTION AND SYNTHESIS We documented how reviewers described methods for addressing intransitivity when assessing certainty of evidence, how often they rated down for intransitivity and their explanations for rating down. RESULTS Of the 268 eligible systematic reviews, 44.8% (120/268) mentioned intransitivity when describing methods for assessing the certainty of evidence. Of these, 28.3% (34/120) considered effect modifiers and from this subset, 67.6% (23/34) specified the effect modifiers; however, no systematic review noted how they chose the effect modifiers. 15.0% (18/120) mentioned looking for differences between the direct comparisons that inform the indirect estimate. No review specified a threshold for difference in effect modifiers between the direct comparisons that would lead to rating down for intransitivity. Reviewers noted rating down indirect evidence for intransitivity in 33.1% of systematic reviews, and noted intransitivity for network estimates in 23.0% of reviews. Authors provided an explanation for rating down for intransitivity in 59.6% (31/52) of the cases in which they rated down. Of the 31 in which they provided an explanation, 74.2% (23/31) noted they detected differences in effect modifiers and 67.7% (21/31) specified in what effect modifiers they detected differences. CONCLUSIONS A third of systematic reviews with NMAs using the GRADE approach rated down for intransitivity. Limitations in reporting of methods to address intransitivity proved considerable. Whether the problem is that reviewers neglected to address rating down for transitivity at all, or whether they did consider but not report, is not clear. At minimum systematic reviews with NMAs need to improve their reporting practices regarding intransitivity; it may well be that they need to improve their practice in transitivity assessment. How to best address intransitivity may remain unclear for many reviewers thus additional GRADE guidance providing practical instructions for addressing intransitivity may be desirable.

Abstract
BACKGROUND Self-assembling peptide (SAP) P11-4 was introduced to treat initial caries lesions by means of guiding hydroxyapatite regeneration within the lesion. The objective of this study was to assess its effectiveness in a practical clinical setting. METHODS Caries lesions in permanent teeth treated with monomeric and polymeric SAP P11-4 from May 2015 through October 2020 were retrospectively analyzed at lesion and child levels by means of bite-wing radiography for changes in stage and cavitation and restoration. RESULTS Two hundred and nineteen children aged 10 through 19 years with a total of 405 proximal lesions in posterior teeth were followed from 0.4 through 5.5 years (median, 7 months; interquartile range, 6-19 months). Regression occurred in 37% of stage RA1 (radiolucency in the outer one-half of enamel) (95% CI, 31% to 44%), 38% of stage RA2 (radiolucency in the inner one-half of enamel plus or minus the enamel-dentin junction) (95% CI, 30% to 45%), and 40% of stage RA3 (radiolucency limited to the outer one-third of dentin) (95% CI, 16% to 68%) lesions. The proportion of lesions with no cavitation was 0.96 (95% CI, 0.94 to 0.98) after 1 year and 0.91 (95% CI, 0.88 to 0.95) after 2 years. CONCLUSIONS Real-world clinical data indicate that SAP P11-4 can lead to recovery and a healthier tooth stage. PRACTICAL IMPLICATIONS SAP P11-4 is a safe treatment for initial caries lesions in permanent teeth that remineralizes in the deepest zone of the lesion and can be introduced easily into routine dental practice.

Abstract
This research was conducted to further support previous studies on the effectiveness of 38% silver diamine fluoride on caries arrest. In addition, the number of applications, time between subsequent applications, type of teeth (primary vs. permanent), final restoration following treatment, and the type of restoration, if any, were assessed. It is a retrospective longitudinal study that was conducted using a chart review technique for which a waiver of informed consent was obtained. The research participants' privacy was ensured and protected. All participants' identities remained anonymous and confidential. Furthermore, consent was collected from participants' sitters during their appointments as a protocol prior to applying 38% silver diamine fluoride (SDF). The current research was reviewed and approved by the Research Ethics Committee at King Faisal Specialist Hospital and Research Center (KFSH&RC). All investigators abided by the rules and regulations of the Government of Saudi Arabia, KFSH&RC, and the Research Advisory Council. A population of pediatric patients with primary and/or mixed dentition at a tertiary care hospital who were treated at the dental office between the period from March 2020 to December 2022 were recruited. A consecutive non-random sampling technique was used. The inclusion criteria include cavitated, asymptomatic, and teeth with no signs or symptoms of pulpal involvement. The sample size estimation was done by considering different percentages of success in arresting dental carries by using 38% SDF, with different levels of precision of 95% confidence intervals and with 0.05 level of significance. A 95% success was assumed in arresting dental carries by using 38% SDF, with a precision of ±5%, and with α=0.05, the required teeth sample size was 101. Anticipating some incomplete information and documentation, the sample size may be dynamic. Nighty-seven teeth both primary and permanent were included in this study. Data were analyzed using IBM SPSS Statistical software version 26.0 (Armonk, NY: IBM Corp.) for Windows. Descriptive statistics (mean standard deviation, frequencies, and percentages) were used to describe the quantitative and categorical outcome variables. Pearson's chi-square test and Fisher's exact test were used to compare the proportion success of 38% SDF in relation to the characteristics of study subjects. The odds ratios were used to quantify the measure of association between the success and other categorical study variables. A binary multiple logistic regression was used to identify the independent variables associated with the success of 38% SDF in arresting dental caries. A p-value of <0.05 and 95% confidence intervals were used to report the statistical significance and precision of results. Our current research concluded that different variables associated with 38% SDF, such as the number of applications and the time-lapse between applications, had no significant effect on the successful results of the application. Moreover, receiving a final restoration did not affect the success of the treatment when compared to treating with 38% SDF alone. Additionally, the type of final restoration had no impact on the prognosis. Further research using standardized protocols for study designs, detection criteria, outcomes, and statistical designs is needed to support findings and establish treatment guidelines.

Abstract
This meta-research aimed to provide an overview of the methodological quality and risk of bias of network meta-analyses (NMA) in dentistry. Searches for NMA of randomized clinical trials with clinical outcomes in dentistry were performed in databases up to January 2022. Two reviewers independently screened titles/abstracts, selected full texts, and extracted the data. The adherence to PRISMA-NMA reporting guideline, the AMSTAR-2 methodological quality tool, and the ROBIS risk of bias tool were assessed in the studies. Correlation between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results was also investigated. Sixty-two NMA studies were included and presented varied methodological quality. According to AMSTAR-2, half of the NMA presented moderate quality (n = 32; 51.6%). The adherence to PRISMA-NMA also varied. Only 36 studies (58.1%) prospectively registered the protocol. Other issues lacking of reporting were data related were data related to the NMA geometry and the assessment of results consistency, and the evaluation of risk of bias across the studies. ROBIS assessment showed a high risk of bias mainly for domains 1 (study eligibility criteria) and 2 (identification and selection of studies). Correlation coefficients between the PRISMA-NMA adherence and the AMSTAR-2 and ROBIS results showed moderate correlation (rho < 0.6). Overall, NMA studies in dentistry were of moderate quality and at high risk of bias in several domains, especially study selection. Future reviews should be better planned and conducted and have higher compliance with reporting and quality assessment tools.

Aims and Objectives The aim of this study was to systematically review the ability of resin infiltration to conceal demineralized enamel lesions to normal enamel translucency and to maintain color stability. Materials and Methods A literature search of PubMed, MEDLINE, Web of Science, and Scopus databases and a manual search of articles from 2009 to 2021 for randomized controlled trials (RCTs) and clinical efficacy trials (nonrandomized) were performed. Methodological quality and risk of bias (RoB) of included papers was assessed using Cochrane Collaboration Risk of Bias Tool 2.0 for RCTs and ROBINS-I (Risk Of Bias In Non-randomized Studies of Interventions) tool for nonrandomized studies. Results A total of 352 titles and abstracts were reviewed. Eight RCTs and three clinical efficiency studies were included in this review. The masking effects of the demineralized enamel lesion were reported immediately after resin infiltration, and the color stability of this material was up to 24 months, with no adverse effects noted. For RCTs, four studies were classified as "some concerns" and four were as "low RoB." For nonrandomized studies, all of the studies presented an overall moderate RoB. Conclusion Resin infiltration achieves the best esthetic outcomes compared with microabrasion and remineralization therapy. Color stability was achieved with this material for up to 24 months and no adverse effects were noted. Factors contributing to the esthetic outcomes of the resin include the elimination of the hypermineralized surface layer, the homogeneity of the resin itself, and polishing after resin infiltration. Longitudinal follow-up and improved control of confounding variables should characterize future high-quality systematic reviews.

Jabbour Z, Kim M, Hayashi M, Kim R. Phosphoric Acid Etch Partially Restores the Initial Bond Strength of Composite to Silver Diamine Fluoride-Treated Enamel Using Universal Adhesives. Dent J (Basel) 2023; 11:161. [PMID: 37504227 PMCID: PMC10378314 DOI: 10.3390/dj11070161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 06/23/2023] [Accepted: 06/26/2023] [Indexed: 07/29/2023] Open
Abstract
BACKGROUND Restoring bonding composite to silver diamine fluoride (SDF)-treated enamel is challenging. This study investigates if phosphoric acid etch restores composite bond strength to SDF-treated enamel using universal adhesives. METHODS Twenty-four recently extracted permanent teeth were randomly divided into 4 (2 experimental (SDF) and 2 control (CTR)) groups: SDF+Water: SDF (1 min) then water rinse (15 mL); CTR+Water: no treatment and water rinse (15 mL); SDF+Etch+Water: SDF (1 min), 35% phosphoric acid (40 s) then water rinse (15 mL); CTR+Etch+Water no treatment, 35% phosphoric acid (40 s) then water rinse (15 mL). The enamel surface in all the groups was bonded (All-Bond Universal) to 4-5 mm composite blocks (Z-250). Each sample was sectioned, and 6-8 beams (1 mm × 1 mm) were selected. The micro-tensile bond strength was measured by dividing the micro-tensile force peak by the adhesive surface area. Univariate ANOVA and Chi-square were used for between-group comparisons with p < 0.05. RESULTS SDF+Water had significantly lower tensile strength compared to all the groups (p < 0.05). Although no difference was found in the tensile strength between the SDF+Etch+Water and the CTR+Etch+Water, the SDF+Etch+Water had significantly more adhesive failures compared to the CTR+Etch+Water (p = 0.047). CONCLUSIONS While phosphoric acid etch seems to restore the initial composite bond strength to SDF-treated enamel, the long-term success of composite restorations bonded to SDF-treated enamel may need further investigation.

The effectiveness of topical fluoride agents on preventing development of approximal caries in primary teeth: a randomized clinical trial. BMC Oral Health 2023; 23:349. [PMID: 37268914 DOI: 10.1186/s12903-023-03045-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Accepted: 05/14/2023] [Indexed: 06/04/2023] Open
Abstract
BACKGROUND This 18-month randomized clinical trial aimed to compare the effectiveness of two topical fluoride applications versus placebo control on preventing development of approximal caries in primary teeth. METHODS Preschool children were recruited if they had at least one initial approximal carious lesion at the distal surface of the canines, both approximal surfaces of the first molars, or the mesial surface of the second molars assessed from bitewing radiographs. The participants were randomly allocated into 3 intervention groups: Group 1 (placebo control), Group 2 (5% sodium fluoride [NaF] varnish), and Group 3 (38% silver diamine fluoride [SDF]). All agents were applied semiannually. Two calibrated examiners evaluated the caries development from bitewing radiographs. Caries development was recorded when the baseline sound surface or initial approximal carious lesion surface developed dentin caries (beyond the outer one-third of dentine) at the follow-up examination. The intention-to-treat approach was adopted. The Chi-square test was used to analyze the effectiveness of topical fluoride agents in preventing approximal caries development and the effect of other variables. The multi-level logistic regression analysis was performed to assess the relative effectiveness of topical fluoride agents in preventing approximal caries development at the 18-month follow-up. RESULTS At baseline, 190 participants with 2,685 sound or initial carries at the approximal surfaces were recruited. No differences in participant demographic backgrounds, oral health related habits, or caries experience were observed among the 3 groups (P > 0.05). After 18 months, 155 (82%) participants remained in the study. The rates of developing approximal caries in Groups 1, 2, and 3 were 24.1%, 17.1%, and 27.2%, respectively (P < 0.001, χ2 test). After adjusting for confounding factors and clustering effect, the multilevel logistic regression analysis showed no differences in caries development rates between the 3 groups (P > 0.05). Tooth type and the extent of a carious lesion at baseline were the significant factors for caries development. CONCLUSION At 18-month follow-up, after adjusting for confounding factors and clustering effect, there were no statistically significant differences in preventing of approximal caries development between the semiannual application of 5%NaF, 38%SDF, or placebo. TRIAL REGISTRATION The study was registered in the Thai Clinical Trials Registry under the number TCTR20190315003 on 15/03/2019.

Systematic review and meta-analysis on the effect of self-assembling peptide P 11-4 on arrest, cavitation, and progression of initial caries lesions. J Am Dent Assoc 2023:S0002-8177(23)00189-7. [PMID: 37245138 DOI: 10.1016/j.adaj.2023.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 02/14/2023] [Accepted: 03/10/2023] [Indexed: 05/29/2023]
Abstract
BACKGROUND Simple noninvasive evidence-based interventions for caries are needed to overcome limitations in the restorative paradigm. The self-assembling peptide P11-4 is a noninvasive intervention that regenerates enamel in initial caries lesions. STUDIES REVIEWED The authors conducted a systematic review and meta-analysis on the effectiveness of the P11-4 products Curodont Repair (Credentis; now manufactured by vVARDIS) (CR) and Curodont Repair Fluoride Plus (Credentis; now manufactured by vVARDIS) on initial caries lesions. Primary outcomes were lesion progression after 24 months, caries arrest, and cavitation. Secondary outcomes were changes in merged International Caries Detection and Assessment System score categories, quantitative light-induced fluorescence (QLF; Inspektor Research System), esthetic appearance, and lesion size. RESULTS Six clinical trials met the inclusion criteria. Results of this review represent 2 primary and 2 secondary outcomes. When compared with parallel groups, use of CR likely results in a large increase in caries arrest (relative risk [RR], 1.82 [95% CI, 1.32 to 2.50]; 45% attributable risk [95% CI, 24% to 60%]; number needed to treat [NNT], 2.8) and likely decreases lesion size by a mean (SD) of 32% (28%). The evidence also suggests that use of CR results in a large reduction in cavitation (RR, 0.32 [95% CI, 0.10 to 1.06]; NNT, 6.9) and is uncertain about lowering merged International Caries Detection and Assessment System score (RR, 3.68 [95% CI, 0.42 to 32.3]; NNT, 19). No studies used Curodont Repair Fluoride Plus. No studies reported adverse esthetic changes. PRACTICAL IMPLICATIONS CR likely has clinically important effects on caries arrest and decreased lesion size. Two trials had nonmasked assessors, and all trials had elevated risks of bias. The authors recommend conducting longer trials. CR is a promising treatment for initial caries lesions. The protocol for this systematic review was registered a priori with PROSPERO (304794).

Abstract
To assess the in vitro and in situ effect of experimental combined fluoride and calcium nanocomposite solutions on dental caries prevention. Nanocompound mesoporous silica (MS) with calcium (Ca) and sodium fluoride (NaF) - (MSCaNaF); MS with NaF (MSNaF), NaF solution (positive control), and deionized water (negative control - CG) were studied. The specimens (n=130) were submitted in vitro to a multispecies biofilm in the presence of 2% sucrose. After 24 h and 48 h, the culture medium pH, the percent of surface mineral loss (%SML), and lesion depth (ΔZ) were analyzed. In the in situ study, 10 volunteers participated in four phases of 7-days each. The products were applied on the specimens (n=240) before 20% sucrose solution drips. The polysaccharides (SEPS and IEPS), %SML and roughness (Sa) were evaluated. There was an in vitro decrease in pH values in 24h and 48h, compared to baseline. The MSCaNaF and MSNaF groups obtained lower values of %SML and ΔZ (p < 0.05) than CG and NaF after 24h and were similar to NaF after 48h (p<0.05). In situ results showed similar SEPS and IEPS among all groups after 48h. An after 7-days, the nanocomposites had similar values (p>0.05), while NaF was similar to CG (p>0.05). After 48h, the MSCaNaF and MSNaF reduced the %SML (p<0.05). After 7-days, both experimental nanocomposites were similar to NaF (p>0.05). Regarding Sa, MSCaNaF was better than NaF for both periods (p<0.05). The nanocomposites controlled the in vitro and in situ enamel demineralization, mainly in the initial periods.

Abstract
Contemporary paradigms of dental caries management focus on the biological approaches to treating the disease and its principal symptom, the carious lesion. This narrative review traces the evolution of carious lesion management from the operative and invasive approaches of G. V. Black's era to the current period of minimally invasive biological approaches. The paper explains the rationale for adopting biological approaches to dental caries management and lists the five core principles of this management approach. The paper also details the aims, features, and the most recent evidence base for the different biological carious lesion management approaches. Based on current practice guidelines, collated clinical pathways for lesion management are also presented in the paper to aid clinicians in their decision-making. It is hoped that the biological rationale and evidence summarized in this paper will bolster the shift to modern biological carious lesion management approaches among dental practitioners.

Abstract
Early caries lesions consist of noncavitated subsurface demineralization caused by the dissolution of hydroxyapatite from the surface to the subsurface area of the enamel. Such lesions cannot be remineralized effectively by the conventional treatment. Thus, there is a need for a noninvasive technique capable of delivering the remineralizing agent to subsurface sites. For this purpose, fluoride iontophoresis (IP) using weak currents has been investigated with some conflicting results and no information on the crystal structure and composition. Because enamel remineralization involves the role of fluid from dentin, the presence of enamel fluid is necessary to determine the repair associated with the physiological condition. This study aimed to investigate structural and compositional characteristics, including the remineralizing effect of 5% sodium fluoride (NaF) IP with different polarities, cathodal iontophoresis (CIP), and anodal iontophoresis (AIP) for the treatment of natural enamel caries under simulated pulpal pressure. A bulk measurement of the crystal structure inside the lesion was first determined using calcium (Ca) K-edge X-ray absorption spectroscopy. IP with both polarities significantly promoted subsurface remineralization. The CIP generated a significant increase in the Ca/phosphorus ratio, and fluoride at the surface lesion significantly correlated with higher mineral density (MD) and more strengthening crystal structure of the lesion volume, while the lesion's MD and other impurities at the lesion surface, mostly the carbonate ions, affected the significant increase in MD with the unchanged structure of the lesion volume after AIP. The CIP of NaF is an ideal method for rapid enamel remineralization and recrystallization of fluoroapatite/fluorohydroxyapatite.

Abstract
INTRODUCTION The American Dental Association (ADA) defines evidence-based dentistry (EBD) as "an approach to oral healthcare that requires the judicious integration of systematic assessments of clinically relevant scientific evidence, relating to the oral and medical condition and history, with the dentist's clinical expertise and the patient's treatment needs and preferences." Clinical practice guidelines (CPGs) are statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options. Therefore, ADA CPGs are the most rigorous examples of EBD to inform clinical practice. CPGs should be of the highest level of quality to ensure the appropriateness and timeliness of clinical recommendations. OBJECTIVES The aim of this study was to measure the methodological rigor and transparency of the ADA CPGs. METHODS Each ADA CPG was appraised by 4 independent assessors using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Quantitative quality scores were obtained for 6 domains and overall quality. In addition, assessors provided a qualitative analysis by providing comments for each item and an appraisal of the full recommendation. RESULTS A quality score of 75% was used as the threshold for high-quality guidelines. Using this metric, 6 of the current 10 current ADA CPGs were considered to be of high quality, 1 was slightly below the quality threshold, and 3 were considered marginal. Even among those evaluated to be high quality in overall assessment, certain domains did not reach the quality threshold of 75%. CONCLUSION Overall, the ADA CPGs collectively provide high-quality guidance for the clinician. While the AGREE appraisal guidelines have been used in CPG development since 2016, there is still room for improvement in certain domains (i.e., stakeholder involvement, rigor of development, applicability, and editorial independence). KNOWLEDGE TRANSFER STATEMENT The results of this study summarize the methodological rigor and transparency of the 10 current ADA clinical practice guidelines. Since adoption of AGREE standards (2016), CPGs have been uniformly of high quality. The quality of older CPGs was somewhat lower but overall deemed acceptable. Thus, ADA CPGs may be used with confidence to inform practitioners of treatment options supported by rigorous evidence-based dentistry standards. However, there is still room for improvement in methodological quality.

Abstract
OBJECTIVE The International Caries Classification and Management System (ICCMS™), a comprehensive, evidence-informed, best clinical practice system, comprises a 4D cycle: 1D-Determine risk; 2D-Detect and assess lesions; 3D-Decide on a personalized care plan; and 4D-Do preventive and tooth-preserving care. The aim of this study was to establish how Colombian dental practitioners, educators and students diagnose and manage caries risk and caries lesions using the COM-B model and the ICCMS™ system. METHODS A total of 1094 participants (practitioners: n = 277; educators: n = 212; students: n = 605) completed a previously validated 79-item questionnaire which explores, based on the COM-B model, the practitioners' self-reported caries diagnosis and management behaviours. Descriptive statistics, Welch's ANOVAs and multiple linear regressions were computed. RESULTS All groups generally performed the behaviours within the 4-D categories 'Most of the time' to 'Always' (students: 4.06 ± 0.95; educators: 3.94 ± 0.98; practitioners: 3.86 ± 1.01). The most frequently performed diagnosis behaviours (1D/2D) were for practitioners assessing initial/moderate lesions (4.09 ± 1.01) and for educators and students cleaning teeth before lesion assessment (4.41 ± 0.80 and 4.38 ± 0.77 respectively). The least frequently performed decision/management (3D/4D) behaviour was non-operative care for moderate-caries lesions (when applicable) (practitioners: 2.64 ± 1.23; educators: 2.68 ± 1.17; students: 3.22 ± 1.41). Opportunity (Resources and Relevance) was the best COM-B predictor for diagnostic behaviours, whereas capability and opportunity (Relevance) were the strongest predictors for management behaviours. CONCLUSION Colombian practitioners, educators and students diagnose and manage caries risk and caries lesions implementing best practice with a high to very high frequency.

Abstract
Developing dental materials for the prevention of remineralization or demineralization is important for high-risk caries patients. This study aimed to evaluate the physicochemical and microbiological effects of adding 45S5 bioglass to resin-modified glass ionomer cement (RMGIC). Samples belonged to the following groups: GIC: conventional glass ionomer cement (Vitro Fil), RMGIC: resin-modified GIC (Vitro Fil LC), and RMGIC/45S5: RMGIC with 10% (wt %) of 45S5. Changes in pH and release of fluoride, calcium, and phosphorus ions under acidic (pH 4) and neutral (pH 7) pH conditions were evaluated. Antibacterial activity was verified based on colony-forming units. Material sorption and solubility were analyzed after bacterial exposure. After 28 days, the bioactivity of the materials was evaluated using scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS). Analysis of variance, post hoc Scheffe, and Tukey (α = 0.05) tests were employed for statistical analysis. RMGIC/45S5 showed higher alkalization activity, calcium release at pH 4 and 7, and sorption than GIC and RMGIC (p < .05). Release of phosphorus and fluoride at pH 4 and 7 was higher for GIC than that for RMGIC and RMGIC/45S5 (p < .05). RMGIC/45S5 showed higher values than RMGIC (p < .05). However, antibacterial activity did not differ among the groups. Precipitates of calcium and phosphorus were visualized in RMGIC/45S5 samples via SEM/EDS. These results indicate that the RMGIC/45S5 promotes alkalization and increases the release of calcium, phosphorus, and fluoride ions, resulting in precipitate deposition rich in calcium and phosphorus, thereby being a promising option to improve the bioactivity of RMGIC.

Abstract
Tooth extraction is the most common hospital procedure for children aged 6-10 years in England. Tooth decay is almost entirely preventable and is inequitably distributed across the population: it can cause pain, infection, school absences and undermine overall health status.An oral health programme (OHP) was delivered in a hospital setting, comprising: (1) health promotion activities; (2) targeted supervised toothbrushing (STB) and (3) staff training. Outcomes were measured using three key performance indicators (KPI1: percentage of children/families seeing promotional material; KPI2: number of children receiving STB; KPI3: number of staff trained) and relevant qualitative indicators. Data were collected between November 2019 and August 2021 using surveys and data from the online booking platform.OHP delivery was impacted by COVID-19, with interventions interrupted, reduced, eliminated or delivered differently (eg, in-person training moved online). Despite these challenges, progress against all KPIs was made. 93 posters were deployed across the hospital site, along with animated video 41% (233/565) of families recalled seeing OHP materials across the hospital site (KPI1). 737 children received STB (KPI2), averaging 35 children/month during the active project. Following STB, 96% participants stated they learnt something, and 94% committed to behaviour change. Finally, 73 staff members (KPI3) received oral health training. All people providing feedback (32/32) reported learning something new from the training session, with 84% (27/32) reporting that they would do things differently in the future.Results highlight the importance of flexibility and resilience when delivering QI projects under challenging conditions or unforeseen circumstances. While results suggest that hospital-based OHP is potentially an effective and equitable way to improve patient, family and staff knowledge of good oral health practices, future work is needed to understand if and how patients and staff put into practice the desired behaviour change and what impact this may have on oral health outcomes.

Abstract
Background:
Resinous infiltrating has proven effective in arresting incipient caries lesions.
Objective:
This study aimed to assess the penetration depth of an experimental resin-infiltrant (75% - TEGDMA, 25% - Bis-EMA, 1% - EDAB, 0.5% camphorquinone), compare it with commercial infiltrant Icon®, and analyze the surface-roughness and microhardness of the resin-materials infiltrated into tooth specimens, before and after pH cycling.
Methods:
To assess penetration depth, sound third molar specimens were submitted to ten de-remineralization cycles for incipient carious lesion induction and were then randomly divided into 2 groups (n=3): (I) Experimental Infiltrant (EI) and (II) Commercial Infiltrant Icon (CI). After resin infiltration into specimens, qualitative Confocal Fluorescence Microscopy images were captured. For roughness and microhardness assessment, new specimens were demineralized, then randomly divided into two groups (n=20): (I) Experimental Infiltrant (EI) and (II) Commercial Infiltrant Icon (CI) and submitted to roughness and microhardness readouts at the following time-intervals: (T1) sound tooth, (T2) white-spot caries lesion, (T3) resin material that infiltrated, and (T4) resin material that infiltrated and was exposed to pH-cycling. In statistical analyses, generalized linear models of repeated measures in time were applied, with a significance level of 5%.
Results:
The experimental infiltrant penetrated the carious lesion and exhibited lower roughness values after its application, even after pH cycling, similar to the CI. The microhardness value of the EI group was significantly lower in the last three-time intervals evaluated compared to CI.
Conclusion:
Experimental resin infiltrant was efficient in penetrating white spot lesions and reducing surface roughness; however, it did not increase surface microhardness.

Abstract
Caries development in children is a prevalent childhood disease. Factors affecting chronic teeth lesions include nutrition, parental involvement, and executing proper dental health attitude. Professional dentists are perceived as role models for the oral health and hygiene of their families. The purposes of the research were 1. To compare caries rates in the children of pediatric dentists and children of general dentists. 2. To compare children’s nutrition habits between pediatric dentists and general dentists. 3. To compare children’s oral health and hygiene between pediatric dentists and general dentists. 4. To compare children’s usage of fluoride-containing products between pediatric dentists and general dentists. A cross-sectional study was conducted by distributing self-reporting questionnaires to pediatric dentists and general dentists via the social media “snowball” platform. The following themes were surveyed: nutrition habits and oral hygiene of the children. The sample consisted of 176 participants. Children of pediatric dentists were found to have fewer cases of caries than children of general dentists (p = 0.018). Nutrition habits did not differ between the two groups. In addition, pediatric dentists reported that their children use more fluoridated toothpaste in comparison with general dentists. Professional training of pediatric dentists contributed to shaping the oral hygiene attitude of their children.

Abstract
IMPORTANCE Dental caries is the most common global childhood disease. To control caries, the Centers for Disease Control and Prevention recommends school-based caries prevention, and the World Health Organization lists glass ionomer cement and silver diamine fluoride as essential medicines for oral disease. OBJECTIVE To determine the noninferiority of silver diamine fluoride with fluoride varnish vs traditional glass ionomer sealants with fluoride varnish after 2 years when provided to children via a school-based health care program. DESIGN, SETTING, AND PARTICIPANTS The CariedAway study is an ongoing single-blind, cluster randomized, noninferiority trial conducted between February 1, 2019, and June 1, 2023, among 2998 children in 47 New York City primary schools. Children aged 5 to 13 years of any race and ethnicity were recruited from block-randomized schools. Inclusion criteria for schools were a student population of at least 50% Hispanic or Latino or Latina ethnicity and/or Black race and at least 80% of students receiving free or reduced-cost lunch. Statistical analysis is reported through March 2022. INTERVENTIONS Children received a single application of silver diamine fluoride with fluoride varnish or an active comparator of glass ionomer sealants and atraumatic restorations with fluoride varnish. MAIN OUTCOMES AND MEASURES Primary outcomes were caries arrest and incidence after a 2-year follow-up, assessed using mixed-effects multilevel models and clustered 2-sample proportion tests. The noninferiority margin was 10%. Intention-to-treat analysis was performed using multiple imputation. RESULTS A total of 2998 children (1566 girls [52.2%]; mean [SD] age at baseline, 6.6 [1.2] years; 1397 Hispanic or Latino or Latina children [46.6%]; 874 [29.2%] with untreated dental caries) were recruited and treated from September 16, 2019, to March 12, 2020. Follow-up observations were completed for 1398 children from June 7, 2021, to March 2, 2022. The mean (SE) proportion of children with arrested caries was 0.56 (0.04) after experimental treatment and 0.46 (0.04) after control treatment (difference, -0.11; 95% CI, -0.22 to 0.01). The mean (SE) proportion of patients without new caries was 0.81 (0.02) after experimental treatment and 0.82 (0.02) after control treatment (difference, 0.01; 95% CI, -0.04 to 0.06). Analysis of imputed data for the full sample did not deviate from per-protocol analyses. There were no adverse events. CONCLUSIONS AND RELEVANCE In this randomized clinical trial, silver diamine fluoride with fluoride varnish was noninferior to sealants and atraumatic restorations with fluoride varnish for caries arrest and prevention. Results may support the use of silver diamine fluoride as an arresting and preventive agent in school-based oral health programs. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03442309.

Abstract
PURPOSE To adapt an evidence-based clinical practice guideline (CPG) for risk-based management of caries in 18-55 year-old Iranian adults. METHODS A multidisciplinary adaptation team reviewed evidence-based guidelines such as the NICE, SIGN, and ADA according to the defined clinical questions. In addition, databases such as the PubMed and Google Scholar were searched and CPGs were screened and appraised using the AGREE II (Appraisal of Guidelines for Research and Evaluation II) tool. Clinical scenarios were developed and their level of evidence, clinical advantage and adaptability were assessed. Following a two-round ranking by experts, the final recommendations were selected using the RAND-UCLA appropriateness method. RESULTS Of 17 CPGs, 5 were selected as the source guidelines for adaptation. To assess the risk of caries in the adult population, reduced Cariogram (without saliva tests) and CAMBRA were suggested as diagnostic tools. In addition, 53 risk-based recommendations on the preventive care (including the use of fluoride toothpaste, fluoride, and chlorhexidine mouthwash, at home and in-office fluoride gel, fluoride varnish, mouth buffering, and sealant), operative intervention threshold, and follow-up interval were adapted for Iranian adults. CONCLUSIONS A guideline was adapted for risk-based management of dental caries in Iranian adults. This helps local dentists in decision making and promoting oral health of adults. Further research is needed to assess the external validity and feasibility of the adapted guideline in the Iranian population.

Abstract
Objectives In recent years, the management of dental caries has evolved significantly. Caries prevention, early detection, and a diagnosis based on risk indicators and risk factor assessments are the most current practical approaches. Furthermore, as proposed in minimally invasive dentistry, the new management approaches preserve healthy tissue and maintain pulp vitality. This article overviews the latest minimally invasive dental caries management and treatment options. The information will assist the reader in the early detection, diagnosis, and treatment of dental caries. Materials and Methods The PubMed (MEDLINE) search engine was used to gather the most relevant information on dental caries. The search was restricted to five years (May 30, 2018-May 29, 2022), and only English-language studies were accessed. A Boolean search of the PubMed data set was implemented to combine a range of keywords. The following filters were applied: abstract, free full text, full text, clinical trial, randomised control trial, systematic review, meta-analysis, and review. More studies were also obtained by manual searches from Google Scholar and textbooks on dental caries. Results By using this process, 683 articles and studies were obtained. The most relevant published studies were chosen and used in the current review. The selected articles are included in the references list. However, the search extended to cover the last five years as our understanding and management of dental caries have changed significantly. Conclusions Early detection and diagnosis of caries based on risk indicators and risk factor assessments are effective. Furthermore, minimally invasive restorative techniques are beneficial in managing dental caries and preserving healthy tissue and should be used whenever possible. This new information, knowledge, and materials should encourage professionals to implement this method. Having a strategy and system based on patient-centred care is critical, and our dental responsibilities must prioritise patient-centred care.

Abstract
This concise review provides an update of the use of dental sealants. Dental sealants protect a tooth from caries development by providing a physical barrier to microorganism colonisation and creating a favorable environment for patients to clean. Some sealants release fluoride ions to promote remineralization. Dental sealants can be applied on pits and fissures of primary and permanent teeth to prevent and arrest early enamel caries. They are effective in caries prevention. The preventive fraction of resin sealant is up to 61% after 5 years. Dental sealants can be classified as resin, glass ionomer and hybrid (compomer or giomer) according to the material. Recent studies from 2012 to 2022 showed resin sealant has a high retention rate of up to 80% after 2 years, whereas glass ionomer sealants is 44%. Chemical etching with 37% phosphoric acid is the standard of care, whereas laser or air-abrasion cannot does not increase the sealant retention rate. Moist control is critical and studies found the use of rubber dam and cotton rolls had similar success for sealant retention. The longevity of dental sealant is also associated with clinical operative factors, including approaches of moisture control, enamel pretreatment, selection of dental adhesive, and time of acid etching.

Abstract
OBJECTIVE Deep margin elevation (DME) is a treatment approach to relocate the cervical margin of teeth with subgingival defects to a supragingival position with a direct restoration to facilitate rubber dam isolation, impression taking, and bonding of indirect restorations. This article provides an overview of the current scientific evidence on DME and future directions for research. OVERVIEW The review included 38 studies on DME, most conducted in vitro. These studies indicate that DME has no detrimental effect on the fracture resistance of restored teeth. Evidence on the impact of DME on marginal quality is conflicting, but most in vitro studies observed no negative effect. Clinical studies, most comprising small patient cohorts, demonstrated favorable restorative outcomes and suggest that DME restorations made with scrupulous care are compatible with periodontal health. Bleeding on probing may occur more frequently at sites with DME, though evidence on this is not unequivocal. CONCLUSIONS Current evidence, based largely on laboratory studies and limited clinical data, supports DME as a viable approach to restore teeth with localized subgingival defects. However, further clinical studies with long-term follow-ups are required to provide corroborative evidence. CLINICAL SIGNIFICANCE Current evidence suggests that DME is a viable approach to restore teeth with localized subgingival defects as a possible alternative to surgical crown lengthening. Proper working field isolation, meticulous care in the bonding and buildup procedure, and biofilm removal through patient-performed oral hygiene and professional maintenance care are crucial. As scant clinical trial-based evidence is available today, further research is needed to evaluate the long-term performance of DME restorations and their impact on periodontal health.

Abstract
The resin infiltration (RI) technique was introduced as one of the minimal intervention dentistry strategies in addressing dental caries among the paediatric population. This technique used the low-viscosity resin monomer to infiltrate the non-cavitated carious lesion and other developmental enamel porosities, thus allowing the conservation of the tooth structure. This narrative review aims to explore the value of RI in Paediatric Dentistry. Through our search of the literature, the development of the material, their clinical applications and shortcomings, as well as the innovation that has been carried out to improve the current RI, were discussed. There are number of high-level evidence supporting the use of RI in arresting non-cavitated proximal caries lesions in primary and permanent teeth, but its efficacy in managing anterior white spot lesions is still unclear. Limited penetration depth, not radiopaque and questionable long-term colour and material stability were among the limitation of the material. Various laboratory-based studies have been conducted to improve the current properties of RI. Nevertheless, RI has emerged as one of the important micro-invasive techniques in addressing non-cavitated and anterior white-spot enamel lesions in children and adolescents with great success.

Abstract
BACKGROUND Dental caries remain a significant global health challenge. Unfortunately, current dental materials lack sufficient antimicrobial power to address the pathogenic species involved in this disease. In this study the potential to load a dental resin blend (RB) with riboflavin (B2) for use in an antimicrobial photodynamic therapy (aPDT) approach was investigated. METHODS B2 was added to our experimental RB (0.1 - 10 wt%). Upon investigating the degree of conversion and specimen integrity of the RB as a function of B2 concentration, it was determined that loading should be restricted to 0.1, 1.0, and 1.5 wt%. Subsequent investigation included water sorption (WS) and solubility (SL), as well as shear bond strength (SBS) and flexural strength (FS) of the specimens after 24 h and 28-day water storage. Lastly, the antimicrobial response of Streptococcus mutans (S. mutans) biofilm following 6 h growth and 60 s of blue LED light (1.3 J/cm2) in an aPDT-based approach was measured. RESULTS AND CONCLUSIONS Adding up to 1.5 wt% B2 had minimal impact on the FS or SBS of the RB. However, aging for 28-days notably increased the FS by as much as 50% for the 1.5 wt% B2-loaded RB. In addition, adding 1.5 wt% B2 resulted in a significant reduction in WS/SL of the RB. Lastly, while adding B2 did not change the antimicrobial response, this was an initial study under these conditions and future investigation will seek to optimize light parameters to produce a more agonistic response. Overall, a riboflavin-loaded dental resin shows significant promise for utilization in restorative dentistry with aPDT.

[PMID: 36232217 PMCID: PMC9566773 DOI: 10.3390/ijerph191912917] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 10/06/2022] [Accepted: 10/07/2022] [Indexed: 06/16/2023]
Abstract
A systematic review and meta-analysis were carried out to evaluate the efficacy of silver diamine fluoride (SDF) in controlling caries progression in cavitated primary molars. A search for randomized and non-randomized trials with follow-up > 6 months was performed using PubMed, Scopus and Embase. The Cochrane risk of bias tools were used for the quality assessment. The success rate and odds ratios were chosen to calculate the effect size for the meta-analysis. A total of 792 papers were identified and 9 were selected. A high variability regarding SDF application protocol was found; otherwise, caries arrest was always recorded using visual/tactile methods. Two studies were judged at low risk of bias, six at moderate risk and one at high risk. Data from five studies were aggregated for meta-analysis. Heterogeneity was found moderate (I2 = 35.69%, p = 0.18). SDF application was found to be overall effective (fixed effect model) in arresting caries progression (ES = 0.35, p < 0.01). In a total of 622 arrested lesions, out of 1205 considered, the caries arrest rate was 51.62% ± 27.40% (Confidence = 1.55) using SDF ≥ 38% applied annually or biannually. In conclusion, when applied to active cavitated caries lesions in primary molars, SDF appears to be effective in arresting dental caries progression, especially if applied biannually.

Abstract
The aim of this study was to evaluate the impact of different patterns of dental caries on oral health-related quality of life (OHRQoL) throughout early childhood. This birth cohort study followed 277 children from southern Brazil for 6 years. Demographic and socioeconomic variables were collected at birth. At age 3 years, children's dental caries experience was quantified by the decayed, missing, or filled teeth (dmft) index. At age 6 years, parents answered the Early Childhood Oral Health Impact Scale (ECOHIS). Poisson regression models were used to estimate associations between caries experience and later OHRQoL, presented as the ratio of ECOHIS scores between the groups. The prevalence of dental caries at 3 years of age was 37.5%. In children with caries, lesions only in anterior teeth, only in posterior teeth, and in both dental segments at age 3 were associated with age 6 ECOHIS scores that were 2.7, 7.8, and 6.2 times higher, respectively, than in children without dental caries experience. OHRQoL was worse among children with higher dmft scores. Dental caries lesions in posterior teeth by age 3 years was strongly predictive of adverse impacts on later OHRQoL, presumably as an indicator of continued disease experience in the intervening years.

Color changes and shear bond strength to simulated caries lesions treated with a novel solution of 20% silver nanoclusters in polymethacrylic acid. Sci Rep 2022; 12:15418. [PMID: 36104473 PMCID: PMC9474811 DOI: 10.1038/s41598-022-19757-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 09/05/2022] [Indexed: 11/17/2022] Open
Abstract
The aims of the study were: (1) To compare the staining effect on demineralized dentin simulating caries between silver nanoclusters (AgNCls) synthesized using polymethacrylic acid (PMAA) and silver diammine fluoride (SDF), and (2) to measure the shear bond strength (SBS) of a glass ionomer cement (GIC) to simulated caries lesions with and without the application of AgNCls/PMAA or SDF. Dentine blocks 4 mm thick from twenty-four non-carious third molars were sectioned and coated with nail varnish (Revlon, New York, USA). Simulated caries lesions on occlusal dentin surfaces were created (66 h in 0.05 M acetate buffer 2.2 mM calcium/phosphate pH 5.0). Specimens were divided into groups and treated with (n = 8): (A) 20% AgNCls/PMAA; (B) SDF 38% (Fagamin, Tedequim, Córdoba, Argentina); or (C) without treatment. AgNCls/PMAA or SDF were applied on the exposed surfaces with a microbrush for 10 s. Samples were incubated for 24 h at 37 °C at 100% relative humidity. Surface color was measured according to the CIE-L*a*b* system before and after demineralization (R0 and R1), 24 h and one week after treatment (R2 and R3), using a spectrophotometer (CM-600D Konica Minolta Sesing Inc., Japan). Groups A and B received an extra application of AgNCls/PMAA or SDF before a conventional GIC (Fuji IX-Gold Label, GC Corp, Tokyo, Japan) was bonded using a mold, 4 mm diameter × 3 mm high. For SBS, a Universal Testing Machine (Digimess RS-8000-5, China)—crosshead speed of 1 mm/min—was used. Statistical analysis was performed using ANOVA, Student-t and Scheffe-test at a significance of p < 0.05. Group A presented a stable color p = 0.24 between R1-R2 and R1-R3 in contrast to significant color changes in Group B (p = 0.02). SBS was higher (p < 0.01) in Group A (10.4 ± 2.7 MPa) compared to Groups B (3.3 ± 1.3 MPa) and C (4.0 ± 0.4 MPa), where no differences between the latter groups were observed (p = 0.77). Results of this preliminary study demonstrated that 20% AgNCls/PMAA did not stain simulated carious dentin and improved SBS of the GIC. The relevance of this study relies on the development of a therapeutic system to potentially arrest caries lesions without staining.

Abstract
Background: There is limited information on the effectiveness of 38% silver diamine fluoride (SDF) in managing enamel caries. Objective: This study aimed to compare effectiveness of 38% SDF and 5% Sodium fluoride (NaF) varnish in arresting enamel caries in young children when applied semiannually over 18 months. Methods: A randomized controlled trial was conducted on children aged 1−3 years who had at least one active carious surface. They were allocated into two groups: Group 1 (38% SDF) and Group 2 (5% NaF varnish). Visual-tactile examination was used to assess extent of carious lesions. Enamel caries that did not progress to dentin were classified as having caries arrest. Intention-to-treat analysis was performed. Results: At baseline, 290 children with 1974 tooth surfaces with enamel caries were recruited. Caries arrest rates at the tooth surface level in Group 1 and Group 2 were 59.1% and 58.8%, respectively (p = 0.873), at 18 months. The multilevel logistic regression analysis revealed that tooth position, tooth surface, extent of enamel caries at baseline, caries experience, and brushing with fluoride toothpaste influenced caries arrest (p < 0.05). Conclusion: The semiannual application of 38% SDF and 5% NaF varnish had comparable effectiveness in arresting enamel caries in primary teeth.

Abstract
Caries is the most prevalent chronic noncommunicable disease. Strategies to prevent its onset and early interventions to arrest the progression of early lesions have been emphasised throughout recent decades to avoid or delay the restorative spiral of the tooth. More individuals are retaining their natural teeth into old age, thereby necessitating ongoing restorative dentistry intervention for their maintenance. The aim of this systematic review was to update the state of the art regarding clinical studies reporting the effectiveness of different nonrestorative caries treatment options in the 5-year period from 2017 to 2022. Relevant articles were retrieved from 2 electronic databases, including randomised clinical trials (RCTs) published from January 2017 until April 2022, assessing effectiveness and secondary effects of at least one nonrestorative caries treatment option, carried out with adults and/or children with noncavitated or cavitated carious lesions on either primary or permanent teeth and diagnosed by radiographs or visual/tactile assessment. All 35 included articles presented the results of RCTs with a follow-up period ranging from 6 to 84 months. Most of these studies were considered high-quality articles with a low risk of bias. Sealants and fluoride gels and varnishes were mentioned in 12 studies as effective strategies to prevent the onset of caries lesions and to arrest them in the early stages. Resin infiltration reported high caries arresting rates in noncavitated proximal lesions in 10 publications. Silver diammine fluoride presented high caries-arresting rates in open dentin lesions, both in primary and permanent dentitions as well as in root caries lesions that were accessible for cleansing. New evidence has been published between 2017 and 2022 as the result of numerous clinical studies providing further evidence of the effectiveness of nonrestorative caries treatment options.

Oral-Hygiene-Related Mobile Apps in the French App Stores: Assessment of Functionality and Quality. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19127293.

Abstract
Mobile health apps can contribute to increased quality of individual oral hygiene behaviors. This study provides an overview and an evaluation of quality of oral-hygiene-related mobile apps currently available in Google Play Store and the French Apple App. A shortlist of nine apps was assessed by 10 oral health professionals using the Mobile App Rating Scale. Intraclass correlation was used to evaluate interrater agreement. Best quality scores were obtained by Oral-B (3.4 ± 0.97), Colgate Connect (3.20 ± 0.63), and Preventeeth (3.10 ± 1.1) and worst ones by Mimizaur se brosse les dents (1.80 ± 0.79) and Kolibree (2.30 ± 0.82). The subjective quality scores ranged from 2.62 ± 0.61 (Oral-B) to 1.5 ± 0.61 (MSD). Specificity of the content ranged from 3.46 ± 0.84 (Preventeeth) to 1.78 ± 0.47 (Mimizaur se brosse les dents). Thus, even if oral health professionals positively evaluated the quality of oral-hygiene-related mobile apps, they are less assertive concerning their impact on the user's knowledge, attitudes, and intentions to change, as well as the likelihood of actual change in the oral hygiene behavior. Further investigations are needed to assess whether information from these apps is consistent with oral hygiene recommendations and to determine the long-term impacts of these apps.

Abstract
Objective: To compare the effects of combined treatment of topical fluoride and semiconductor laser (F&L) with topically using fluoride (F) on remineralization and prevention of enamel caries. Background: There is no agreement on whether semiconductor lasers can promote the effect of topical fluoride on the remineralization and prevention of dental caries. This study is the first systematic review and meta-analysis to investigate the pooled effect of data from studies that compared the combined use of semiconductor lasers and topical fluorides with the single use of fluoride on remineralization and prevention of caries. Methods: We performed literature search on Scopus, Web of Science, and PubMed. The keywords were as follows: ((diode lasers) OR (diode laser) OR (quantum cascade laser) OR (quantum cascade lasers) OR (Gallium Aluminum Arsenide lasers) OR (Gallium Aluminum Arsenide laser) OR (GaAlAs lasers) OR (GaAlAs Laser) OR (semiconductor laser) OR (semiconductor lasers)) AND ((caries) OR (dental caries) OR (remineralisation) OR (remineralization) OR (demineralization) OR (demineralisation)) AND fluoride. We carried out meta-analysis to compare the microhardness of demineralized enamel, lesion depth (LD), and percent reduction of calcium (Ca%) of sound enamel receiving F&L with F. Results: The search identified nine laboratory studies, which used 445 to 980 nm semiconductor lasers with various fluorides. The standard mean difference of microhardness of demineralized enamel between F&L and F was 1.06 [95% confidence interval (CI): 0.12 to 2.00, p = 0.03]. No difference was found in LD (95% CI: -1.63 to 0.10, p = 0.08) and Ca% (95% CI: -0.52 to 1.28, p = 0.40) on sound enamel between the two groups. Conclusions: Semiconductor lasers enhance the effect of fluoride on remineralizing but not on preventing enamel caries. Moreover, substantial heterogeneity was found among the studies, and the results should be interpreted cautiously.

Abstract
Enamel demineralisation can develop on smooth surfaces as an undesirable side effect during orthodontic treatment with fixed appliances. This study aimed to evaluate the ability of 38% silver diamine fluoride in remineralisation (as estimated by fluorescence gain) of artificial initial lesions in smooth surfaces of human enamel. The smooth surfaces of 50 human tooth samples were artificially demineralised and 45 samples were allocated randomly into three groups receiving a single treatment with a varnish: group I: Riva Star (silver diamine fluoride, SDF), group II: Bifluorid 12 (NaF, CaF2), and group III: Cervitec F (CHX, CPC, NH4F). Five samples were assigned as a negative control group without treatment. All samples were exposed to pH-cycling for 28 days. Fluorescence behavior was measured using Quantitative light-induced fluorescence before and after demineralisation and up to four weeks on a weekly basis. Analysis of variance (ANOVA) with Tukey–Kramer post-hoc tests and repeated measures ANOVA were used for statistical evaluation (α = 0.05). After demineralisation, all samples showed mean ΔF of − 16.22% ± 4.35, without significance differences between the fluorescence behaviour of the samples (p = 0.251). After 28 days group comparison showed a statistically significant difference (p = 0.034) for ΔF values: the lowest fluorescence values were found in group I (SDF, mean ΔF − 16.47 ± 6.08) with a significant difference compared to group III (Cervitec F, mean ΔF − 11.71 ± 4.83). In group II (Bifluorid 12) mean ΔF value was − 15.55 ± 2.15) without statistically significant differences to groups I and III. The fluorescence behaviour of SDF varnish on smooth surfaces with artificial initial enamel lesions was significantly lower compared to Cervitec F varnish after short time use.

Abstract
Dental Caries is a kind of chronic oral disease that greatly threaten human being's health. Though dentists and researchers struggled for decades to combat this oral disease, the incidence and prevalence of dental caries remain quite high. Therefore, improving the disease management is a key issue for the whole population and life cycle management of dental caries. So clinical difficulty assessment system of caries prevention and management is established based on dental caries diagnosis and classification. Dentists should perform oral examination and establish dental records at each visit. When treatment plan is made on the base of caries risk assessment and carious lesion activity, we need to work out patient‑centered and personalized treatment planning to regain oral microecological balance, to control caries progression and to restore the structure and function of the carious teeth. And the follow-up visits are made based on personalized caries management. This expert consensus mainly discusses caries risk assessment, caries treatment difficulty assessment and dental caries treatment plan, which are the most important parts of caries management in the whole life cycle.

Abstract
The purpose of this study was to investigate the protective effect of a glass ionomer cement (GIC) consisting of fluoro-zinc-silicate glass on the demineralization of bovine dentin using the ultrasonic pulse-echo method. The findings were compared with those obtained using a conventional GIC. Slabs of dentin from bovine teeth were sliced, shaped into a rectangular form, and immersed in 0.5 M ethylenediaminetetraacetic acid solution at 25ºC for 6 days, followed by storage in distilled water for 3 days. After demineralization, they were immersed in artificial saliva with and without the GIC specimens. The propagation times of the longitudinal ultrasonic waves in the samples were measured. The ultrasonic velocities of the fluoro-zinc-silicate glass-containing GICs were significantly increased 2-3 days after the start of the experiment and showed an upward trend thereafter. These findings indicate that the GICs containing fluoro-zinc-silicate glass might exhibit the potential to promote remineralization in the dentin.
