Evaluation of dental cements derived from mixtures of highly reactive ionomer glasses and bottle glass: Cement manipulation, mechanical, fluoride ion releasing, radiopaque and setting properties. Dent Mater 2024:S0109-5641(24)00282-3. [PMID: 39327130 DOI: 10.1016/j.dental.2024.09.013] [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: 05/28/2024] [Revised: 09/11/2024] [Accepted: 09/20/2024] [Indexed: 09/28/2024]
Abstract
OBJECTIVES To evaluate the mechanical properties, fluoride release, radiopacity, and setting characteristics of dental cements derived from highly reactive ionomer glasses and bottle glass mixtures. METHODS Two highly reactive glass series, LG99 and LG117, were synthesized, milled, sieved, and characterized using XRD and laser particle size analysis. These glasses were mixed with predetermined ratios of ground bottle glass, poly(acrylic acid), and aqueous tartaric acid to form glass ionomer cements. The cements' working time (WT), setting time (ST), fluoride release, radiopacity, compressive strength (CS), and elastic modulus (EM) were evaluated. Mean differences in CS were analyzed using multivariate ANOVA with Tukey's post hoc test at p = 0.05. RESULTS The WT and ST for both groups ranged from 1.5 to 2.5 min. LG99 series cements showed significantly higher CS (∼65 MPa) and EM (∼2 GPa) than LG117 series (p < 0.05). Both series showed similar fluoride release profiles, peaking at 1.2 mmol/L at 28 days. Radiopacity for LG99 ranged from 0.97 to 1.34, while LG117 ranged from 0.60 to 0.95. Solid state 27Al magic-angle spinning-nuclear magnetic resonance (MAS NMR) confirmed the presence of Al(IV) and Al(VI), indicating setting completion by one day for both series. Bottle glass showed a chemical shift at 55.8 ppm, overlapping with LG99's Al(IV) signal. The 19F MAS NMR spectra revealed Al-F and F-Sr(n) species in all glasses, with LG117 forming CaF2 after one day in deionized water. CONCLUSION Mixtures of highly reactive ionomer glass and bottle glass produced cements with satisfactory properties for dental applications. Further research is needed to optimize their formulation and properties.

Abstract
Dental restorative procedures remain a cornerstone of dental practice, and for many decades, dental amalgam was the most frequently employed material. However, its use is declining, mainly driven by its poor aesthetics and by the development of tooth-coloured adhesive materials. Furthermore, the Minamata Convention agreed on a phase-down on the use of dental amalgam. This concise review is based on a FDI Policy Statement which provides guidance on the selection of direct restorative materials as alternatives to amalgam. The Policy Statement was informed by current literature, identified mainly from PubMed and the internet. Ultimately, dental, oral, and patient factors should be considered when choosing the best material for each individual case. Dental factors include the dentition, tooth type, and cavity class and extension; oral aspects comprise caries risk profiles and related risk factors; and patient-related aspects include systemic risks/medical conditions such as allergies towards certain materials as well as compliance. Special protective measures (eg, a no-touch technique, blue light protection) are required when handling resin-based materials, and copious water spray is recommended when adjusting or removing restorative materials. Cost and reimbursement policies may need to be considered when amalgam alternatives are used, and the material recommendation requires the informed consent of the patient. There is no single material which can replace amalgam in all applications; different materials are needed for different situations. The policy statement recommends using a patient-centred rather than purely a material-centred approach. Further research is needed to improve overall material properties, the clinical performance, the impact on the environment, and cost-effectiveness of all alternative materials.

Abstract
BACKGROUND Glass ionomers may be a good alternative to composite resin restorations in special needs patients with challenging behaviours. The present study was carried out to evaluate the restorative efficacy of glass ionomer in the occlusal cavities of permanent molars among patients with special needs after one year of follow-up. MATERIAL AND METHODS A randomized split-mouth study was made of a cohort of patients with special needs. First and second permanent molars with occlusal caries were treated with glass ionomer, silver amalgam and composite resin. Assessments were made at 3, 6 and 12 months, using a scale based on the original code of Ryge and the USPHS criteria. RESULTS A total of 34 patients and 102 restorations comprised the study sample. The survival rate of both the glass ionomer and silver amalgam was 100%, versus 97.1% in the case of composite resin. The glass ionomer afforded good marginal adaptation and stable color, with no fractures or secondary caries. CONCLUSIONS The glass ionomer remained successfully for one year in the occlusal cavities of the permanent molars, with the same survival rate as silver amalgam, and better survival than composite resin, in the patients with special needs.

Abstract
Silver diamine fluoride (SDF) and atraumatic restorative treatment (ART) are treatment modalities that are minimally invasive and used for the prevention and control of dental caries. The amalgamation of these two techniques has led to the development of silver modified atraumatic restorative treatment (SMART). In this approach the carious lesion is restored with glass-ionomer cement (GIC) after SDF application. SMART effectively arrests caries without removing additional tooth structure, making it a promising option for caries management in children who lack cooperative ability.This article reviews the literature on SMART, the evidence regarding its applications in dental practice, its advantages, drawbacks, the scope for research, and clinical use.

Abstract
OBJECTIVES To undertake a cost-effectiveness analysis of restorative treatments for a first permanent molar with severe molar incisor hypomineralization from the perspective of the Brazilian public system. MATERIALS AND METHODS Two models were constructed: a one-year decision tree and a ten-year Markov model, each based on a hypothetical cohort of one thousand individuals through Monte Carlo simulation. Eight restorative strategies were evaluated: high viscosity glass ionomer cement (HVGIC); encapsulated GIC; etch and rinse adhesive + composite; self-etch adhesive + composite; preformed stainless steel crown; HVGIC + etch and rinse adhesive + composite; HVGIC + self-etch adhesive + composite, and encapsulated GIC + etch and rinse adhesive + composite. Effectiveness data were sourced from the literature. Micro-costing was applied using 2022 USD market averages with a 5% variation. Incremental cost-effectiveness ratio (ICER), net monetary benefit (%NMB), and the budgetary impact were obtained. RESULTS Cost-effective treatments included HVGIC (%NMB = 0%/ 0%), encapsulated GIC (%NMB = 19.4%/ 19.7%), and encapsulated GIC + etch and rinse adhesive + composite (%NMB = 23.4%/ 24.5%) at 1 year and 10 years, respectively. The benefit gain of encapsulated GIC + etch and rinse adhesive + composite in relation to encapsulated GIC was small when compared to the cost increase at 1 year (gain of 3.28% and increase of USD 24.26) and 10 years (gain of 4% and increase of USD 15.54). CONCLUSION Within the horizon and perspective analyzed, the most cost-effective treatment was encapsulated GIC restoration. CLINICAL RELEVANCE This study can provide information for decision-making.

Abstract
Objective To enhance the survival rate of atraumatic restorative treatment (ART) restorations using (class I and class II) bilayer technique of placing glass ionomer cement (GIC) along with nanofilled coating (NC) over the restorations, thereby improving longevity. Study design A total of 178 primary molars in 67 children were selected and randomly divided into four groups. Group IA was treated with a single layer of GIC, followed by a protective layer of petroleum jelly in class I restoration. Group IB was treated with a single layer of GIC, followed by a protective layer of petroleum jelly in class II restoration. Group IIA was treated with bilayer GIC restoration followed by NC of GC-Coat Plus in class I, whereas group IIB was treated with bilayer GIC restoration followed by GC-Coat Plus in class II. Clinical analysis of all three groups was performed at 1, 3, 6, 9, and 12 months to evaluate the success of treatment procedures using predetermined criteria. Pearson's Chi-square and Kaplan-Meier estimates were utilized to evaluate the success of all four treatment procedures (p < 0.05). Results Out of 178 teeth, 33 teeth were in group IA, 36 teeth were in group IB, 43 teeth were in group IIA, and 40 teeth were available for evaluation at the end of the 12-month follow-up period. The overall success was determined to be 81% for group IA, 79.2% for group IB, 79.5% for group IIA, and 88.6% for IIB. At 6th-month follow-up, one clinical failure was observed in groups IA and IB. At 9 months follow-up, two clinical failures were observed in both group IA and group IB and three failures were observed in group IIB. At 12 months follow-up, four clinical failures were observed in group IA, three in group IB and one clinical failure was observed in group IIB. There was no statistically significant difference observed between the success of the four groups, suggesting that either of the techniques can be utilized for ART. Conclusion No statistically significant difference was observed between the survival of class I and class II restorations of both the groups, indicating that either single-layer or bilayer technique along with NC can be adopted for the management of dental caries in primary molars using the ART approach.

Effect of Biosilicate ® Addition on Physical-Mechanical and Biological Properties of Dental Glass Ionomer Cements. J Funct Biomater 2023; 14:302. [PMID: 37367266 DOI: 10.3390/jfb14060302] [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: 03/28/2023] [Revised: 05/26/2023] [Accepted: 05/27/2023] [Indexed: 06/28/2023] Open
Abstract
This study investigated the influence of incorporating Biosilicate® on the physico-mechanical and biological properties of glass ionomer cement (GIC). This bioactive glass ceramic (23.75% Na2O, 23.75% CaO, 48.5% SiO2, and 4% P2O5) was incorporated by weight (5%, 10%, or 15%) into commercially available GICs (Maxxion R and Fuji IX GP). Surface characterization was made by SEM (n = 3), EDS (n = 3), and FTIR (n = 1). The setting and working (S/W time) times (n = 3) and compressive strength (CS) were analyzed (n = 10) according to ISO 9917-1:2007. The ion release (n = 6) was determined and quantified by ICP OES and by UV-Vis for Ca, Na, Al, Si, P, and F. To verify cell cytotoxicity, stem cells from the apical papilla (SCAP) were exposed to eluates (n = 3, at a ratio of 1.8 cm2/mL) and analyzed 24 h post-exposure. Antimicrobial activity against Streptococcus mutans (ATCC 25175, NCTC 10449) was analyzed by direct contact for 2 h (n = 5). The data were submitted for normality and lognormality testing. One-way ANOVA and Tukey's test were applied for the working and setting time, compressive strength, and ion release data. Data from cytotoxicity and antimicrobial activity were submitted for Kruskal-Wallis' testing and Dunn's post hoc test (α = 0.05). Among all experimental groups, only those with 5% (wt) of Biosilicate® showed better surface quality. Only M5% showed a comparable W/S time to the original material (p = 0.7254 and p = 0.5912). CS was maintained for all Maxxion R groups (p > 0.0001) and declined for Fuji IX experimental groups (p < 0.0001). The Na, Si, P, and F ions released were significantly increased for all Maxxion R and Fuji IX groups (p < 0.0001). Cytotoxicity was increased only for Maxxion R with 5% and 10% of Biosilicate®. A higher inhibition of S. mutans growth was observed for Maxxion R with 5% of Biosilicate® (less than 100 CFU/mL), followed by Maxxion R with 10% of Biosilicate® (p = 0.0053) and Maxxion R without the glass ceramic (p = 0.0093). Maxxion R and Fuji IX presented different behaviors regarding Biosilicate® incorporation. The impacts on physico-mechanical and biological properties were different depending on the GIC, but therapeutic ion release was increased for both materials.

Abstract
AIM To compare the clinical outcomes of silver-modified atraumatic restorative technique (SMART) vs atraumatic restorative technique (ART) in primary teeth. MATERIALS AND METHODS This study was a randomized clinical trial conducted on 30 children. The study was split-mouth design, so each group was consisted of 30 children. Children aged 3-6 years old of both genders. Communication with the children was established. Gross debris from cavitation was removed. Carious dentin on walls was excavated using spoon excavator and low-speed contra with round or fissure bur. The areas to be treated were isolated with cotton rolls. For ART, glass ionomer cement (GIC) was applied according to the manufacturer's instructions. For silver-modified atraumatic restorative technique (SMART), a protective coating was applied to the lips and skin to prevent a temporary tattoo. Silver diamine fluoride (SDF) was applied carefully using bended microsponge brush. It was applied directly to only the affected tooth surface. The lesion was dried for 15 seconds with gentle flow of compressed air. After 1 week, GIC was applied according to the manufacturer's instructions. Clinical evaluation was done for all teeth at 6 and 12 months. The data were collected and then statistically analyzed using the Chi-square test to show the difference between groups. RESULTS The restoration of the first primary molar with ART restoration alone showed a lower success rate when compared with the restoration with a combination of SDF and ART (SMART technique), with percentages of 70% and 76.67% and 53.33% and 60% after 6 months and 12 months of follow-up, respectively. CONCLUSION Silver diamine fluoride is successful in arresting dentin caries and can be used to increase the efficacy of the ART technique in primary teeth. CLINICAL SIGNIFICANCE It is recommended to use SDF as a noninvasive approach to control dentin caries with the ART technique.

Abstract
The aim of this systematic review was to update an existing review on the management of dental caries lesions in patients with disabilities so as to provide an up-to-date summary of the evidence. Randomized clinical trials and cohort studies related to preventive and restorative programmes for dental caries among people requiring special care, published in English, Spanish, Portuguese, French and German languages from February 1st 2011 to April 1st 2022, were retrieved from three databases ("updated review"). From the 1,105 titles identified using the search topic "Caries AND Disability", 17 papers informed in the analyses: 6 referring to caries preventive strategies and 11 related to restorative care strategies. Most of these studies targeted children and adults with intellectual/physical disability, although preventive and therapeutic strategies were also reported for frail older adults and onchohematological patients. Fluorides in tablets, gels or varnishes forms and the use of xylitol as a sugar substitute were reported as effective approach to prevent the onset of caries in high-risk groups. Minimally intervention treatment options such as the Hall technique, the ART approach and the use of SDF for arresting caries, were deemed suitable and effective strategies for treating existing lesions in-office. In conclusion, in the past decade (2011-2022) an increased number of articles reported strategies to prevent and manage caries among people requiring special care. Although an array of preventive and therapeutic strategies for dental caries exists, more and better-quality clinical evidence is needed to offer guidance to inform policy and practice for special care dentistry.

Abstract
INTRODUCTION Dental caries in the adult population that require preventive and therapeutic treatment are generally neglected in rural communities. The determination of the effectiveness of the application of 38% silver diamine fluoride (SDF) in arresting caries lesions when combined with atraumatic restorative treatment (ART) is very important, as it serves as a preventive and restorative procedure to regain the function of the permanent dentition. The assessment of optimal SDF application with ART, in comparison with ART alone, in managing cavitated carious lesions in a pragmatic setting, is the need of the hour to recommend optimal dental care, especially in rural settings which have minimal access to comprehensive dental care. METHODS AND ANALYSIS The clinical trial will enrol 220 adults (18-65 years) with cavitated carious lesions attending the Amrita School of Dentistry in the Ernakulam district, India. This study is a randomized, controlled trial with a 1:1 allocation ratio in two parallel groups. Study arm 1 will receive 38% SDF application and ART, and study arm 2 will receive ART only. A digital radiograph will be taken immediately after restoration (baseline) as well as at the end of the 6th month for evaluation of caries arrest. The assessment of the survival of the restoration will be done on the 7th day, 30th day, and at the end of the 6th month. The final analysis would include both the tooth and person levels. ETHICS AND DISSEMINATION This trial adheres to the principles of the Declaration of Helsinki and the guidelines of the Indian Council of Medical Research (ICMR). This study protocol has been approved by the Institutional Review Board. This trial has been registered prospectively with the Clinical Trial Registry of India (Registration No: CTRI/2021/12/038816).

Clinical and Microbiological Evaluation of a Chlorhexidine-Modified Glass Ionomer Cement (GIC-CHX) Restoration Placed Using the Atraumatic Restorative Treatment (ART) Technique. MATERIALS 2022; 15:ma15145044. [PMID: 35888511 PMCID: PMC9320984 DOI: 10.3390/ma15145044] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 07/13/2022] [Accepted: 07/15/2022] [Indexed: 12/04/2022]
Abstract
The aims of this study were to investigate the clinical effectiveness and patient acceptability of a modified glass ionomer cement placed using the atraumatic restorative treatment (ART) technique to treat root caries, and to carry out microbiological analysis of the restored sites. Two clinically visible root surface carious lesions per participant were restored using ART. One was restored with commercial glass ionomer cement (GIC) (ChemFil® Superior, DENTSPLY, Konstonz, Germany) which acted as the control. The other carious root lesion was restored with the same GIC modified with 5% chlorhexidine digluconate (GIC-CHX; test). Patient acceptability and restoration survival rate were evaluated at baseline and after 6 months. Plaque and saliva samples around the test and control restorations were collected, and microbiological analysis for selected bacterial and fungal viability were completed at baseline, and after 1, 3, and 6 months. In total, 52 restorations were placed using GIC and GIC-CHX in 26 participants; 1 patient was lost to follow-up. After reviewing the restorations during their baseline appointments, participants indicated that they were satisfied with the appearance of the restorations (n = 25, 96%) and did not feel anxious during the procedure (n = 24, 92%). Forty-eight percent (n = 12) of the GIC-CHX restorations were continuous with the existing anatomic form as opposed to six for the GIC restorations (24%), a difference which was statistically significant (p = 0.036). There was no statistically significant reduction in the mean count of the tested microorganisms in plaque samples for either type of restorations after 1, 3, or 6 months. Restoration of carious root surfaces with GIC-CHX resulted in higher survival rates than the control GIC. ART using GIC-CHX may therefore be a viable approach for use in outreach dental services to restore root surface carious lesions where dental services are not readily available, and for older people and special needs groups.

Abstract
Modern restorative dentistry would not be possible without the ability to bond to tooth structure. The development of dental adhesives has a lengthy gestation, from the beginnings around 1950, to the latest generation: modern universal adhesives, which were introduced during the 2010s. The foundation for these developments was a deeper understanding of the mechanisms of adhesion to the tooth structure, and to restoration materials. Typically, the performance of an adhesive does not depend on the use of a single ingredient, but on an overall balanced and optimised formulation that contains various components with different roles, such as functional adhesive monomers.While a wealth of literature exists on adhesives that have a long and successful clinical history ('gold standards'), some universal adhesives have also accumulated a lot of scientific evidence while offering benefits like ease of use, low technique sensitivity and versatility.To achieve reliable results with a modern adhesive, several tips should be kept in mind regardless of the product, which result in a homogeneous adhesive layer, proper cure and ultimately high bond strength. Although high performance is already achieved with the adhesives currently available, this is still an exciting area of ongoing research.

Abstract
The complex role of water in glass ionomer cement (polyalkenoate) dental restorative materials has been studied, but much of the present understanding concerning water balance within these materials is based on very early studies and short-term experiments. This study evaluated the nature of the water species of six conventional and four resin modified glass ionomer restorative materials over 3 years using thermogravimetric analysis techniques. Materials were prepared, placed in crucibles, and stored in physiologic phosphate buffered saline and evaluated at 24 h, 1 week, and then at 1, 3, 6, 9, 12, 18, 24, 30 and 36 months. All materials demonstrated a significant increase in unbound water percentage content but except for the resin modified materials, the enthalpy required to remove the unbound water species did not significantly change over 36 months. Also, bound water content percentage and removal enthalpy was established at 24 h, as no significant increase was noted in both bound water content and removal enthalpy over the course of this evaluation. This study suggests that unbound water species may increase with time and is loosely held except for the resin modified materials. Protective coatings placement and re-evaluation are prudent to prevent unbound water loss.

Abstract
Objectives
To investigate the shear bond strength and microleakage of glass ionomer cement (GIC) containing silver diamine fluoride (SDF).
Materials and Methods
Sound human permanent premolars were divided into the following three groups: 1) GIC (Fuji IX), 2) GICSDF-S: GIC + SDF (Saforide), and 3) GICSDF-T: GIC + SDF (Topamine). Shear bond strength (
n
= 14/group) was measured using a universal testing machine and compared between groups (one-way ANOVA and Tukey HSD,
p
< 0.05). Microleakage (
n
= 15/group) at enamel and dentin margins was scored using a stereomicroscope (10x) and compared between groups (Chi-square,
p
< 0.05).
Results
There were significant differences in shear bond strength between the GIC and GICSDF-S groups and between the GIC and GICSDF-T groups. The GIC group had the lowest shear bond strength among the groups; however, there was no significant difference between the GICSDF-S and GICSDF-T groups. The microleakage test results were not significantly different between groups at the enamel margin or dentin margins. Although the GIC group demonstrated a higher dye penetration score at the enamel and dentin margins, the difference was not significant.
Conclusions
Within the limitations of this study, we conclude that incorporating SDF into GIC results in higher shear bond strength while not increasing microleakage at the enamel and dentin margins.

Abstract
Overall perspective of nanotechnology and reinforcement of dental biomaterials by nanoparticles has been reported in the literature. However, the literature regarding the reinforcement of dental biomaterials after incorporating various nanostructures is sparse. The present review addresses current developments of glass ionomer cements (GICs) after incorporating various metallic, polymeric, inorganic and carbon-based nanostructures. In addition, types, applications, and implications of various nanostructures incorporated in GICs are discussed. Most of the attempts by researchers are based on the laboratory-based studies; hence, it warrants long-term clinical trials to aid the development of suitable materials for the load bearing posterior dentition. Nevertheless, a few meaningful conclusions are drawn from this substantial piece of work; they are as follows: (1) most of the nanostructures are likely to enhance the mechanical strength of GICs; (2) certain nanostructures improve the antibacterial activity of GICs against the cariogenic bacteria; (3) clinical translation of these promising outcomes are completely missing, and (4) the nanostructured modified GICs could perform better than their conventional counterparts in the load bearing posterior dentition.

Abstract
OBJECTIVES To compare pain perception of young children treated with SDF and ART, as well as their parents' acceptability of both modalities. METHODS Eighty, 3 to 8-years old children, having at least one deciduous asymptomatic tooth with active caries, as defined by the ICDAS II scores 4, 5, 6 were randomly assigned into two groups; SDF for caries arresting in the test group, and ART for caries removal in the control group. Pain perception was assessed using Sound, Eye, Motor scale (SEM), whereas parental acceptability was assessed using a self-administered questionnaire. RESULTS Patients treated with SDF reported significantly less discomfort and pain compared to the ART group, with a mean SEM of 3.70 ± 1.47 and 6.18 ± 3.06, respectively (p < 0.001). A significantly higher mean parental acceptability score was detected for SDF treatment (31.85 ± 2.30) than ART treatment (26.75 ± 3.60), p < 0.001, with regard to the treatment duration, child comfortability and quality of treatment (p < 0.001). The only dimension showing more satisfaction for the ART treatment was esthetics of anterior teeth (p= 0.01). CONCLUSIONS Parental acceptability was higher for the SDF caries treatment of primary teeth compared to ART treatment, especially in relation to the shorter intervention time, child comfortability and acceptance as well as quality of treatment. CLINICAL SIGNIFICANCE The shorter average time needed and the ease of application of SDF on cavitated primary lesions, in addition to parental acceptability, place SDF in an advantageous position over the ART on clinical level.

Abstract
BACKGROUND In this paper, we describe the design, program details, and baseline demographics and oral health of participants in ForsythKids, a regional, comprehensive, school-based mobile caries prevention program. METHODS We solicited all Massachusetts elementary schools with greater than 50% of students receiving free or reduced-price meals. Six schools initially elected to participate, ultimately followed by over 50 schools. Interventions were based on systematic reviews and randomized controlled caries prevention trials. Participating students received semiannual dental examinations, followed by comprehensive preventive care. Summary statistics regarding oral health indicators were derived from individual tooth- and surface-level data. RESULTS Over a 6-year period, data were collected on 6927 children. The number of students per school ranged from 58 to 681. The overall participation rate was 15%, ranging from 10% to 29%. Overall, 57% of the children were younger than 8 years at baseline. Approximately, 54% of children experienced dental decay on any tooth at baseline; 32% had untreated decay on any tooth, 29% had untreated decay on primary teeth, and 10% untreated decay on permanent teeth. CONCLUSIONS Untreated dental decay was double the national average, even in schools within several blocks of community dental clinics. These data demonstrate the need for caries prevention beyond the traditional dental practice.

Abstract
Dental amalgam has been successfully used for the restoration of carious lesions for more than 180 years. It is clinically characterized by high longevity and low technique sensitivity. For decades, dental amalgam has been discussed in the public, especially due to its roughly 50% mercury content. Since the Minamata Convention was published in 2013 with the primary goal of reducing the anthropogenic mercury release into the environment, the previously muted amalgam discussion has received fresh impetus. Another considerable disadvantage of amalgam is its silver/greyish color, which simply no longer matches patients' esthetic demands.The present paper describes the basic problems with amalgam against the background of multiple biological, clinical, and health policy factors. Possible consequences of the Minamata Convention concerning legal regulations as well as the use of dental biomaterials and therefore also relating to the future national healthcare system are discussed. Finally, possible amalgam alternatives and the urgent need for biomedical research towards restorative dentistry are presented, embedded into the crucial question of whether we are actually conducting the correct debate.

[PMID: 34321731 PMCID: PMC8281857 DOI: 10.4103/ijcm.ijcm_226_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Accepted: 12/22/2020] [Indexed: 11/04/2022] Open
Abstract
Background Atraumatic restorative treatment (ART) approach helps reduce barriers to restorative care for the patients. This study was done to compare the survival rate and cost-effectiveness of conventional and ART restorations at time-intervals of 6, 12, and 18 months among anganwadi preschool children in Bengaluru city. Materials and Methods 133 children aged 3-5 years attending anganwadi centers in Bengaluru city based on inclusion and exclusion criteria were recruited for the present study. A split-mouth technique was used in which the participants received two types of carious cavity excavation techniques (conventional and ART) followed by restoration using glass ionomer cement. Comparison and evaluation were made at the end of 6 months, 12 months and 18 months intervals to check for the survival rate and cost-effectiveness. Results The survival rates of ART when compared to conventional restorations were higher at 6 months and 12 months 97.7% and 93.07%, respectively, and at 18 months survival rate of conventional restorations were higher. The cost-effectiveness ratio (CER) of the ART restoration was lower when compared to conventional restorations. Conclusion The carious cavities restored using ART techniques had a better survival rate at 12 months and lower CER when compared to the conventional technique.

Abstract
BACKGROUND This study assessed the cost-effectiveness of atraumatic restorative treatment and the Hall Technique approach (ART/HT) in managing dental caries in young children under the health provider perspective in order to explore a best-buy alternative to dental general anaesthesia (DGA). METHODS Sixty-five observations from a randomized controlled trial were used to construct 20 000 microsimulations representing individual-level clinical outcome and costs of the DGA and ART/HT. Outcome was percentage of successfully managed cases. Costs were reported in 2020 price. Three different scenarios with different assumptions of clinical success of the DGA and the ART/HT were analysed. Probabilistic sensitivity analysis was carried out. RESULTS The ART/HT successfully managed more cases at lower cost ($557) than the DGA when the system failure of the DGA was considered. Under per protocol analysis, participants in both arms were successfully managed, but the ART/HT costed $580 less than the DGA. Probabilistic sensitivity analysis confirmed the ART/HT was a dominant intervention. CONCLUSIONS The ART/HT approach was non-inferior in managing dental caries in young children but at lower costs than the DGA. The ART/HT could be a viable option in the provision of comprehensive dental care in locations with limited access to DGA and reduce hospital admission.

Comparison of two minimally invasive restorative techniques in improving the oral health-related quality of life of pregnant women: a six months randomized controlled trial. BMC Oral Health 2021; 21:221. [PMID: 33931037 PMCID: PMC8086316 DOI: 10.1186/s12903-021-01581-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 04/21/2021] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND Women tend to delay dental treatment due to misconceptions regarding the safety of dental procedures during pregnancy which may negatively affect their quality of life. Minimally invasive restorative techniques offer alternatives for caries treatment and can improve their oral health-related quality of life (OHRQoL) during this stage. METHODS A randomized controlled clinical trial was conducted in 2019 and included 162 pregnant women visiting public family health centers in Alexandria, Egypt, with mild to moderate dental pain due to caries. Participants were randomly assigned into Papacarie-Duo group (n = 82) and ART group (n = 80). The outcome variable was percent change in OHRQoL (oral health impact profile, OHIP-14) after 6 months. T test/Mann Whitney U test were used to compare groups and a multivariable linear regression analysis was conducted to evaluate the factors affecting the outcome variable. RESULTS A significant reduction (P < 0.002) was noted in OHIP-14 between baseline and 6 months indicating improvement in OHRQoL in the Papacarie-Duo and ART groups (16.26% and 18.91%, P = 0.120 in bivariate analysis). Multiple linear regression revealed significantly greater reduction in OHIP-14 scores in the Papacarie-Duo than the ART group (regression coefficient = 4.03, 95% confidence interval: 0.652, 7.409, P = 0.020). CONCLUSION Minimally invasive restorative techniques, such as ART and chemo-mechanical caries removal using Papacarie- Duo can improve the OHRQoL of pregnant women suffering from mild to moderate pain due to dental caries. Significantly more improvement was noted in the Papacarie-Duo group after adjusting all other variables.

Abstract
Plasma is an electrically conducting medium that responds to electric and magnetic fields. It consists of large quantities of highly reactive species, such as ions, energetic electrons, exited atoms and molecules, ultraviolet photons, and metastable and active radicals. Non-thermal or cold plasmas are partially ionized gases whose electron temperatures usually exceed several tens of thousand degrees K, while the ions and neutrals have much lower temperatures. Due to the presence of reactive species at low temperature, the biological effects of non-thermal plasmas have been studied for application in the medical area with promising results. This review outlines the application of cold atmospheric pressure plasma (CAPP) in dentistry for the control of several pathogenic microorganisms, induction of anti-inflammatory, tissue repair effects and apoptosis of cancer cells, with low toxicity to healthy cells. Therefore, CAPP has potential to be applied in many areas of dentistry such as cariology, periodontology, endodontics and oral oncology.

Abstract
BACKGROUND The public dental care sector is striving to fulfill the preventive and restorative needs of Egyptians, including pregnant women, who may not receive timely care due to misconceptions about dental treatment during pregnancy. Because of this, they are likely to suffer dental pain, with higher risk of infection affecting their offsprings. AIM OF THE STUDY To compare the effectiveness of chemo-mechanical caries removal using Papacarie-Duo and Atraumatic Restorative Treatment (ART) in reducing dental pain among pregnant women. MATERIALS AND METHODS A randomized controlled clinical trial was conducted, in 2019, and included 162 pregnant women visiting family health centers in Alexandria, Egypt, with dental pain due to dental caries not extending to pulp. Patients were randomly assigned to Papacarie-Duo group (n = 82) and ART group (n = 80) after stratification by number of treated surfaces. The outcome variables were reduction in pain assessed using Visual Analogue Scale (VAS), satisfaction with treatment, and time taken for dental caries removal. T test/ Mann Whitney U test were used to compare groups and Freidman test was used to compare change across time. RESULTS Pain reduction was significantly greater in the Papacarie-Duo than the ART group (81.55% and 69.43%, P = 0.001). Patients in the Papacarie-Duo group were significantly more satisfied with treatment than those in the ART, immediately after treatment (mean = 9.60 and 8.00, P = < 0.01) and after 6 months (mean = 9.63 and 8.16, P = < 0.01). Significantly less excavation time was recorded in the Papacarie-Duo group than in the ART group (mean = 10.38 and 11.56 min, P = < 0.01). CONCLUSION Chemo-mechanical caries removal using Papacarie-Duo is more effective in reducing dental pain, in pregnant women, and is associated with more satisfaction and less excavation time than ART.

Abstract
OBJECTIVE The aim of this paper is to present the results of a consensus meeting on the threshold property requirements for the clinical use of conventional glass-ionomer cements (GICs) for restorative indications. METHODS Twenty-one experts on GICs evaluated the results of tests on mechanical and optical properties of 18 different brands of restorative GICs: Bioglass R [B], Chemfil Rock [CR], Equia Forte [EF], Gold Label 2 [GL2], Gold Label 9 [GL9], Glass Ionomer Cement II [GI], Ionglass [IG], Ion Z [IZ], Ionomaster [IM], Ionofil Plus [IP], Ionostar Plus [IS], Ketac Molar Easymix [KM], Magic Glass [MG], Maxxion R [MA], Riva Self Cure [R], Vidrion R [V], Vitro Fil [VF] and Vitro Molar [VM]. All experiments were carried out by a team of researchers from Brazil and England following strict protocols, under the same laboratory conditions throughout, and maintaining data integrity. RESULTS There was consensus on: determining as primary properties of the material: compressive strength, microhardness, acid erosion and fluoride release, and as secondary properties: contrast ratio and translucency parameter, in order to rank the materials. Seven brands were below the thresholds for restorative indications: IZ, IM, IG, MA, VF, B and MG. CONCLUSIONS Based on the primary properties adopted as being essential for restorative indications, the conventional restorative GICs that met the thresholds and could be considered suitable as long-term restorative materials were: EF, GI, GL9, KM, IP, GL2, IS, CR, V, VM and R. A decision-making process to select the best GIC must also include results from clinical trials. CLINICAL SIGNIFICANCE This study provides a ranking of GICs that could be considered suitable as long-term restorative materials based on their main properties.

Abstract
OBJECTIVE To evaluate the translucency parameter (TP) and contrast ratio (CR) of different conventional restorative glass-ionomer cements (GICs). MATERIALS AND METHODS Eighteen brands of GICs were evaluated. Five disks of each material were made following ISO 9917-1. The luminous reflectance and Central Bureau of the International Commission on Illumination parameters of disks were evaluated using a colorimeter, against backings of white and black, to obtain the translucent parameter and contrast ratio of different brands of glass-ionomer cements. The correlation between translucency parameter and contrast ratio was assessed with the Pearson correlation test. The translucent and contrast ratio parameters values were submitted to the one-way ANOVA and Tukey test for multiple comparisons (p < 0.05). RESULTS There was a strong inverse relationship between CR and TP (r2 = 0.94, p < 0.001). The contrast ratio decreased as translucency increased. There were significant differences in TP and CR among brands (p < 0.001). CONLUSIONS GICs exhibit different translucency and contrast ratio behavior. Some brands of GICs presented very low TP and this condition would be unacceptable for areas with esthetic demands. In addition, TP and CR showed a strong linear relationship. CLINICAL SIGNIFICANCE The results found in this study demonstrated that the knowledge of the translucency and CR of different conventional restorative GICs is important in order to guide clinicians in the selection of restorative GICs for anterior teeth.

Abstract
OBJECTIVES Aim of this systematic review was to summarize the factors that affect the success rate of atraumatic restorative treatment (ART) restorations in children. DATA/SOURCES Two independent reviewers conducted a literature search in the databases PubMed, Medline and Web of Science until October 2019 with no initial time limit. Articles reporting on clinical outcomes of ART restorations placed in children were included. STUDY SELECTION A total of 67 articles were included in this review reporting on clinical outcomes of ART restorations placed in children in 47 studies. The overall estimated success rate and 95 % confidence interval (CI) of ART restorations were 0.71 (0.65-0.77) and 0.67 (0.56-0.78) at the 12-month and the 24-month follow-up, respectively. Operator was one of the significant factors associated with the success rate of ART restorations. ART restorations placed by dental students/therapists had a significantly lower success rate compared with those placed by dentists. Besides, type of restoration (single-surface vs. multiple-surface restoration) was also associated with the success rate of ART restorations. Other factors including dentition, restorative material, clinical setting, and moisture control method had no significant influence on the success rate of ART restorations in children. CONCLUSION It is concluded that ART approach can be used to manage cavitated caries lesions in children. Operator and type of restoration are significant factors influencing the success rate of ART restorations. CLINICAL SIGNIFICANCE This study provides valuable information on the factors that affect success rate of ART restorations in children, which helps clinicians to make informed decisions on provision of ART restorations in children.

Abstract
OBJECTIVES Our aim was to systematically assess the efficacy of chlorhexidine (CHX) as a cavity pre-treatment or restoration mix-in on the survival of ART restorations. DATA We included randomized controlled trials that assessed the effect of cavity pretreatment with CHX or the restoration mix-in of CHX on the survival of ART restorations (test group) versus a similar restorative approach without CHX. Risk of bias was assessed using Cochrane's randomized trial quality assessment Tool (RoB 2.0). Random-effects meta-analysis was conducted, with mean Odds Ratios and 95 % confidence intervals (OR, 95 % CI) as effect estimates. The certainty of the evidence was assessed according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. SOURCES Medline, Web of Science, Cochrane Central were searched. Eligible studies were in- or excluded and data extracted for included studies by two reviewers independently. STUDY SELECTION Four studies with 261 patients (mean age 3.8-14.6 years) and 467 ART restorations were included. All studies showed some concerns about the risk of bias. Three studies involving a total of 167 restorations in the CHX group and 188 restorations in the control group, followed up for one year, were submitted to meta-analysis. There were no significant differences between CHX vs. control (OR = 0.79, 95 % CI [0.26, 2.40], P = 0.68, I2 = 3%, P = 0.35). The strength of the evidence was estimated as low. CONCLUSIONS Based on very limited data, CHX pre-treatment or restoration mix-in did not have any significant benefit for survival of ART restorations. CLINICAL SIGNIFICANCE There is a lack of evidence regarding the influence of chlorhexidine on the survival of ART restorations. Our results revealed that there was no significant difference in the survival of ART restorations when CHX was used as a cavity pre-treatment or mix-in.

Abstract
OBJECTIVES This study was designed to investigate the antimicrobial properties, compressive strength and fluoride release capacities of high-viscous glass ionomer cements (GICs) after incorporation of cinnamon and thyme essential oils. MATERIALS AND METHODS Experimental-modified GICs were prepared by incorporation of thyme and cinnamon essential oils into the liquid phase of the cement at 5 and 10% v/v. Antimicrobial activity against selected microorganisms (Streptococcus mutans and Candida albicans) was done using direct contact test. Compressive strength of the four new formulations and control group was tested using a universal testing machine while fluoride ion release was measured by ion-selective electrode at 1, 7, 14 and 28 days. Data analysis and comparisons between groups were performed using factorial and one-way ANOVA and Tukey's tests. RESULTS All newly formulated GICs exhibited significantly higher inhibitory effects against both Streptococcus mutans and Candida albicans growth when compared to conventional GIC (p < 0.05). Compressive strength of 5% cinnamon-modified GIC (MPa = 160.32 ± 6.66) showed no significant difference when compared with conventional GIC (MPa = 165.7 ± 5.769) (p value > 0.05). Cumulative fluoride-releasing pattern at days 7, 14, and 28 were 10% cinnamon-GIC > 5% thyme-GIC > 5% cinnamon-GIC > 10% thyme GIC > conventional GIC. CONCLUSIONS Incorporation of 5% cinnamon oil into glass ionomer resulted in better antimicrobial effects against S. mutans and C. albicans and increased fluoride-release capacity without jeopardizing its compressive strength. CLINICAL RELEVANCE The 5% cinnamon-modified GIC appears to be a promising alternative restorative material in ART technique.

[PMID: 32752201 PMCID: PMC7564959 DOI: 10.3390/jfb11030055] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 07/23/2020] [Accepted: 07/27/2020] [Indexed: 02/06/2023] Open
Abstract
Continuing cariogenic bacterial growth demineralizing dentine beneath a composite filling is the most common cause of tooth restoration failure. Novel composites with antibacterial polylysine (PLS) (0, 4, 6, or 8 wt%) in its filler phase were therefore produced. Remineralising monocalcium phosphate was also included at double the PLS weight. Antibacterial studies involved set composite disc placement in 1% sucrose-supplemented broth containing Streptococcus mutans (UA159). Relative surface bacterial biofilm mass (n = 4) after 24 h was determined by crystal violet-binding. Live/dead bacteria and biofilm thickness (n = 3) were assessed using confocal laser scanning microscopy (CLSM). To understand results and model possible in vivo benefits, cumulative PLS release from discs into water (n = 3) was determined by a ninhydrin assay. Results showed biofilm mass and thickness decreased linearly by 28% and 33%, respectively, upon increasing PLS from 0% to 8%. With 4, 6, and 8 wt% PLS, respectively, biofilm dead bacterial percentages and PLS release at 24 h were 20%, 60%, and 80% and 85, 163, and 241 μg/disc. Furthermore, initial PLS release was proportional to the square root of time and levelled after 1, 2, and 3 months at 13%, 28%, and 42%. This suggested diffusion controlled release from water-exposed composite surface layers of 65, 140, and 210 μm thickness, respectively. In conclusion, increasing PLS release initially in any gaps under the restoration to kill residual bacteria or longer-term following composite/tooth interface damage might help prevent recurrent caries.

Abstract
OBJECTIVES Management of dental caries under dental general anaesthesia (DGA) in young children improves their quality of life. A randomized controlled trial was undertaken to test the changes in oral health-related quality of life among children treated under a DGA or managed using the Atraumatic Restorative Treatment and Hall crown approaches (ARTs). METHODS Children scheduled for a DGA for the management of dental caries after assessment at the Oral Health Centre of Western Australia were invited to participate. Inclusion and exclusion criteria were applied. Child oral health-related quality of life (COHRQoL) was evaluated through the Early Childhood Oral Health Impact Scale (ECOHIS) and the child-specific Caries Impacts and Experiences Questionnaire for Children (CARIES-QC) at baseline and 12 months after consent. The changes in child oral health-related quality of life were analysed on an intention-to-treat basis. Paired t-test and Wilcoxon's matched-pairs rank test were used for within-group comparison and t-test, Mann-Whitney test, and test of proportions for between-group comparisons. Linear regression was used for multivariable analyses of the follow-up scores. RESULTS Sixty-five parents/carers agreed to participate and were randomized (Test = 32; Control = 33). Mean age = 4.7 years, SD 1.1; 51% male. At baseline, there were no statistically significant differences in age and sex between the groups; however, the ARTs group reported higher ECOHIS scores. At follow-up, both the ARTs and DGA groups had lower ECOHIS scores (20.7 vs 12.9 and 14.4 vs 13.3, respectively) and CARIES-QC scores (12.6 vs 7.1 and 9.9 vs 8.4, respectively). The within-group differences in the ARTs group were statistically significant while the differences in the DGA group were not, P < .01 and P > .05, respectively. In a linear regression of the follow-up scores, being in the DGA group increased the follow-up scores, but it was no longer statistically significant while baseline impact scores were significantly associated with greater follow-up scores for both the ECOHIS and the CARIES-QC, P < .01. CONCLUSION The child oral health-related quality life among children scheduled for dental general anaesthesia improved after receiving minimally invasive, atraumatic restorative treatments of dental caries.

Abstract
BACKGROUND A dental general anaesthesia (DGA) is commonly undertaken for the management of dental caries in young children. A randomized-controlled trial was undertaken to test the feasibility of using the Atraumatic Restorative Treatment and Hall Technique approaches (ART/HT) to manage the dental treatment of children recommended for a DGA. METHODS Consenting children, recommended a DGA for caries management, at the Oral Health Centre of Western Australia were randomized. Test group children were treated using the ART/HT approach and the control group under a DGA. Children were examined after 12 months by two blinded, calibrated examiners. Analysis was on an intention to treat basis; between and within group comparisons were undertaken using appropriate paired and unpaired tests. Logistic regression was used to test restorative success, controlling for clustering of teeth. RESULTS Sixty-five children participated, (Test = 32; Control = 33). At study termination, 28 children (88%) in the ART/HT group and 20 children (61%) in the DGA group had been provided with care, P < 0.01. Crown restorations were protective of restorative failure in a multivariate logistic model (OR 0.05, P < 0.01). CONCLUSION Use of the ART/HT approach enabled timely dental treatment of young children recommended for a DGA, and should be among the treatment options considered.

Abstract
Prevention and health promotion are considered important strategies to control oral diseases. Dental caries is preventable disease and remains the most common chronic disease that affects mainly low income children and still considered the main cause of tooth loss in adulthood in Brazil. The aim of this study is to present a System Dynamics model (SDM) specifically developed with the Stella Architect software to estimate the cost and clinical hours required to control the evolution of dental caries in preschool children in Maringá, Brazil. Two main strategies to control caries were considered in the model: the application of fluoride varnish on teeth presenting white spots, and the use of Atraumatic Restorative Treatment (ART) in cavitated carious lesions without pulp involvement. The parameters used in the model were: number of people covered by a local oral health team = 4,000; number of children up to 5 years = 7% of the population; children's decayed, missing, filled teeth (dmft) index = 2.4; time/cost of 4 applications of fluoride varnish = 5 minutes/US$ 0.716; and time/cost of each ART restoration = 15 minutes/US$ 1.475. The SDM generated an estimated total cost of US$698.00, and a total of 112 clinical hours to treat the population in question. The use of the SDM presented here has the potential to assist decision making by measuring the material and human resources required to prevent and control dental caries at an early age.

Abstract
OBJECTIVES The purpose of this article was to review the fluoride release and uptake ability of some restorative materials which are used for minimally invasive procedures. METHODS The literature search on published researches and review articles were carried out by using PubMed, Trip and Cochrane library databases. The search terms used were fluoride, restorative materials, atraumatic restorative treatment or ART, glass ionomer or GIC, resin modified glass ionomer cement or RMGIC. The articles included were between 2000 and 2015. CONCLUSION Fluoride release varies with m factors including the type of restorative materials used and also the media in which it is stored. Fluoride uptake is dependent on the type of the cement and the availability of fluoride including fluoride releasing capacity in the material.

Surface Pre-Reacted Glass Filler Contributes to Tertiary Dentin Formation through a Mechanism Different Than That of Hydraulic Calcium-Silicate Cement. J Clin Med 2019; 8:jcm8091440.

Abstract
The induction of tissue mineralization and the mechanism by which surface pre-reacted glass-ionomer (S-PRG) cement influences pulpal healing remain unclear. We evaluated S-PRG cement-induced tertiary dentin formation in vivo, and its effect on the pulp cell healing process in vitro. Induced tertiary dentin formation was evaluated with micro-computed tomography (μCT) and scanning electron microscopy (SEM). The distribution of elements from the S-PRG cement in pulpal tissue was confirmed by micro-X-ray fluorescence (μXRF). The effects of S-PRG cement on cytotoxicity, proliferation, formation of mineralized nodules, and gene expression in human dental pulp stem cells (hDPSCs) were assessed in vitro. μCT and SEM revealed that S-PRG induced tertiary dentin formation with similar characteristics to that induced by hydraulic calcium-silicate cement (ProRoot mineral trioxide aggregate (MTA)). μXRF showed Sr and Si ion transfer into pulpal tissue from S-PRG cement. Notably, S-PRG cement and MTA showed similar biocompatibility. A co-culture of hDPSCs and S-PRG discs promoted mineralized nodule formation on surrounding cells. Additionally, S-PRG cement regulated the expression of genes related to osteo/dentinogenic differentiation. MTA and S-PRG regulated gene expression in hDPSCs, but the patterns of regulation differed. S-PRG cement upregulated CXCL-12 and TGF-β1 gene expression. These findings showed that S-PRG and MTA exhibit similar effects on dental pulp through different mechanisms.

Abstract
Purpose Ion release from glass ionomer restorative cements (GICs) plays an important role in GICs. The ion release from chitosan and nanodiamond-modified glass ionomers was assessed. Materials and methods Three GICs (Fuji IX, Ketac Universal and Riva Self Cure) were modified in the powder phase per weight by adding 5% or 10% of a commercially available chitosan powder (CH) or nanodiamond (ND) powder to the GICs. The specimens with dimensions 4 mm diameter and 6 mm height manufactured from the 15 GIC formulations were allowed to set for 1 hr and subsequently placed in neutral de-ionised water. The released ions were assessed using inductively coupled plasma-mass spectrometer (ICP-MS) to determine the elemental release. Additionally, three different disc-shaped specimens (3 mm in diameter and 1 mm thick) were constructed from each material for scanning electron microscopy (SEM) and energy dispersive X-ray spectrometry (SEM-EDS) microanalysis to establish an ion weight percentage. Results There were no significant differences in the ion release between the control materials for aluminium, silicon and strontium. The ion release from CH and most ND-modified GICs were significantly (p<0.00001) increased compared to the control materials. CH modifications significantly increased the ion release of aluminium, sodium, silicon and strontium for all three control materials (with the exception of the strontium release from Ketac Universal that was modified with 5% chitosan). Conclusion Ion release can be advantageous to tooth structure due to the interaction of chitosan with the GIC chemistry and moisture during maturation. Ion release up to five times greater than the control was noted for some ions.

Abstract
The cytotoxicity of glass ionomer cements (GICs) was investigated using a novel, cost-effective, easy-to-perform and standardized test. GIC rings were made using in-house designed, custom-made moulds under sterile conditions; 10 with Fuji Equia and 10 with Fuji Triage capsules, placed in direct contact with primary human gingival fibroblasts (HGF) and immortalized human fibroblasts (HFF1). On day 1, 4, 14 and 21, an AlamarBlue® (resazurin) assay was completed towards determining the effects of the GICs on metabolic activities of the cells, whilst cell morphology was examined by light microscopy. The influence of the compounds released from the GIC rings on cell physiological effects (viability, proliferation and adhesion) during 24 h incubation was further investigated by impedimetry. Result trends obtained from this battery of techniques were complementary. At 100 v/v% concentration, the released compounds from Equia were strongly cytotoxic, while at lower concentration (0, 4, 20 v/v%) they were not cytotoxic. In contrast, Triage elicited only slightly transient cytotoxicity. The method proposed has been proved as being efficient, reliable and reproducible and may be useful in quick testing of the cytotoxicity of similar biomaterials by using an immortalized cell line.

Abstract
OBJECTIVES This clinical trial investigated the efficacy of silver diamine fluoride (SDF) in arresting dentine caries in primary molars of preschoolers. Time required for treatment, adverse effects, parental aesthetic perception, anxiety and oral health related to quality of life (OHRQoL) was evaluated. MATERIALS AND METHODS Children, 2-5 years old, with active dentine caries lesions on the occlusal surface of primary molars were randomly allocated to test group (SDF) or control group (atraumatic restorative treatment/ART). The dmf-t/DMF-T and ICDAS indexes determined the presence of caries and activity. The main outcome after 3, 6 and 12-month follow-up was assessed by a blind examiner. The time required to perform the treatments was recorded and a facial image scale was applied to assess anxiety before and after treatment. Adverse events and aesthetic perception were assessed through questions addressed to caregivers; and the OHRQoL through the B-ECOHIS questionnaire. RESULTS In 68 patients that were randomized, the mean number of treated teeth per child was 2.42(1.04) and 2.09(1.18) in the SDF and ART groups (p = 0.074), respectively. The mean difference of arrested lesions between the groups after 12 months was -0,07(0.05; - 0.17-0.30). The time required to treat with SDF was lower than the ART (p < 0.001). There was no difference in the percentage of adverse events + aesthetic perception (p = 0.709), and the change in anxiety (p = 0.155). There was a less impact in OHRQoL after ART treatment, but only when the parents' distress subscale was considered (p = 0.012). CONCLUSION SDF requires much less chair-time and have similar results as ART in arresting caries lesion, anxiety, adverse effects, aesthetic perception and quality of life.

Abstract
OBJECTIVES This study is aimed at evaluating the effect of a new glass ionomer cement (GIC) containing fluoro-zinc-silicate fillers on biofilm formation and ion incorporation. MATERIALS AND METHODS Streptococcus mutans biofilms were developed on two GIC materials: Caredyne Restore (CD) and Fuji VII (FJ); and hydroxyapatite (HA) for 24 h at 37 °C using a flow cell system. The morphological structure and bacterial viability were analyzed using a confocal laser scanning microscopy. Bacterial adhesion during the initial 2 h was also assessed by viable cell counting. To study the ion incorporation, restored cavities prepared on the root surfaces of human incisors were subjected to the elemental mapping of the zinc and fluoride ions in the GIC-dentin interface using a wavelength-dispersive X-ray spectroscopy electron probe microanalyzer. RESULTS Morphological observations revealed that biofilm formation in the CD group was remarkably inhibited compared with the HA and FJ groups, exhibiting sparse, thinner biofilm clusters. The microorganisms adhering to the CD group were significantly inhibited, revealing 2.9 ± 0.4 for CD, 4.9 ± 0.2 for FJ, and 5.4 ± 0.4 log colony-forming units (CFU) for HA. The CD zinc ion incorporation depth was 72.2 ± 8.0 μm. The fluoride penetration of CD was three times deeper than that of FJ; this difference was statistically significant (p < 0.05). CONCLUSIONS Enhanced by the incorporation of zinc and fluoride ions, the new GIC inhibited biofilm formation by interfering with bacterial adhesion. CLINICAL RELEVANCE A novel GIC comprised of fluoro-zinc-silicate fillers may improve clinical outcomes, such as root caries and minimally invasive dentistry.

Abstract
This article presents a discussion paper for both consideration and implementation of Minimal Intervention Dentistry (MID) principles by the general dental practitioner. It argues that if these concepts can be adopted in early childhood by both the community and the profession, "Teeth for Life" can become a reality for all. Oral Health promoting behaviours can be nurtured and supported from infancy and developed into everyday living practice for a lifetime thereby maintaining an optimal quality of life. MID techniques have become more refined and supported by scientific research in the recent times and should be considered an essential clinical guideline for the future disease management.

Survival of occlusal ART restorations using high-viscosity glass-ionomer with and without chlorhexidine: A 2-year split-mouth quadruple-blind randomized controlled clinical trial. J Adv Res 2019; 17:117-123. [PMID: 31193330 PMCID: PMC6526224 DOI: 10.1016/j.jare.2019.01.015] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 01/25/2019] [Accepted: 01/26/2019] [Indexed: 11/20/2022] Open
Abstract
Comparing the survival of HVGICs (with and without CHX) using ART criteria. Comparing the survival of HVGICs (with and without CHX) using FDI criteria. Compare the effect of the two restorations on caries development. No significant difference in the survival percentages between the two types of HVGICs. The addition of CHX to the HVGIC is not recommended.
The study question was whether the use of high-viscosity glass-ionomer with chlorhexidine (HVGIC/CHX) for the Atraumatic Restorative Treatment (ART) prepared cavities could achieve a higher restoration survival percentage and be more effective for preventing dentine carious lesions adjacent to the restoration than the use of HVGIC without CHX. The study followed a split-mouth, quadruple-blind, randomized controlled clinical design and lasted 2 years. Patients with at least two small- to medium-sized occlusal cavities were included. The occlusal cavities were prepared according to the ART method and restored with HVGIC/CHX (test) and HVGIC (control). A replica of all restorations available and digital photographs were fabricated at baseline and after 0.5, 1, 1.5 and 2 years and evaluated by two examiners using the ART and Federation Dentaire International (FDI) restoration assessment criteria. Survival curves were constructed using the Kaplan-Meier method, and the log-rank test was used to test for significance between the survival percentages. A total of 100 subjects with an average age of 14.4 years participated. According to the ART restoration assessment criteria, the 2-year survival percentages of ART/HVGIC/CHX (96.8%) and ART/HVGIC (94.8%) did not differ significantly and no significant difference was found between the test (97.9%) and control (96.9%) groups according to the FDI restoration assessment criteria. Eight and five occlusal restorations failed according to the ART and FDI restoration criteria, respectively. No dentine carious lesions along the restoration margin were observed. The 2-year survival of ART restorations in both groups was high. The development of carious dentine lesions adjacent to the restoration was not observed in either treatment group. There is no evidence for modifying HVGIC by incorporating chlorhexidine in order to prevent dentine carious lesion development or to improve the survival of ART restorations in occlusal surfaces in permanent teeth. HVGIC without chlorhexidine can be used successfully to restore occlusal ‘ART-prepared’ cavities in permanent teeth.
