ABSTRACT

Importance: Dental caries is the world's most prevalent noncommunicable disease and a source of health inequity; school dental sealant programs are a common preventive measure. Silver diamine fluoride (SDF) may provide an alternative therapy to prevent and control caries if shown to be noninferior to sealant treatment. Objective: To determine whether school-based application of SDF is noninferior to dental sealants and atraumatic restorative treatment (ART) in the prevalence of dental caries. Design, Setting, and Participants: The Silver Diamine Fluoride Versus Therapeutic Sealants for the Arrest and Prevention of Dental Caries in Low-Income Minority Children (CariedAway) study was a pragmatic noninferiority cluster-randomized clinical trial conducted from February 2018 to June 2023 to compare silver diamine fluoride vs therapeutic sealants for the arrest and prevention of dental caries. Children at primary schools in New York, New York, with at least 50% of the student population reporting as Black or Hispanic and at least 80% receiving free or reduced lunch were included. This population was selected as they are at the highest risk of caries in New York. Students were randomized to receive either SDF or sealant with ART; those aged 5 to 13 years were included in the analysis. Treatment was provided at every visit based on need, and the number of visits varied by child. Schools with preexisting oral health programs were excluded, as were children who did not speak English. Of 17 741 students assessed for eligibility, 7418 were randomized, and 4100 completed follow-up and were included in the final analysis. Interventions: Participants were randomized at the school level to receive either a 38% concentration SDF solution or glass ionomer sealants and ART. Each participant also received fluoride varnish. Main Outcomes and Measures: Primary study outcomes were the prevalence and incidence of dental caries. Results: A total of 7418 children (mean [SD] age, 7.58 [1.90] years; 4006 [54.0%] female; 125 [1.7%] Asian, 1246 [16.8%] Black, 3648 [49.2%] Hispanic, 153 [2.1%] White, 114 [1.5%] multiple races or ethnicities, 90 [1.2%] other [unspecified], 2042 [27.5%] unreported) were enrolled and randomized to receive either SDF (n = 3739) or sealants with ART (n = 3679). After initial treatment, 4100 participants (55.0%) completed at least 1 follow-up observation. The overall baseline prevalence of dental caries was approximately 27.2% (95% CI, 25.7-28.6). The odds of decay prevalence decreased longitudinally (odds ratio [OR], 0.79; 95% CI, 0.75-0.83) and SDF was noninferior compared to sealants and ART (OR, 0.94; 95% CI, 0.80-1.11). The crude incidence of dental caries in children treated with SDF was 10.2 per 1000 tooth-years vs 9.8 per 1000 tooth-years in children treated with sealants and ART (rate ratio, 1.05; 95% CI, 0.97-1.12). Conclusions and Relevance: In this school-based pragmatic randomized clinical trial, application of SDF resulted in nearly identical caries incidence compared to dental sealants and ART and was noninferior in the longitudinal prevalence of caries. These findings suggest that SDF may provide an effective alternative for use in school caries prevention. Trial Registration: ClinicalTrials.gov Identifier: NCT03442309.

ABSTRACT

The aim of minimal intervention dentistry (MID) is to maximize the preservation of dental tissues through the use of modern and effective techniques and procedures. The central objective of MID is to increase the functional life of dental elements and, consequently, the quality of life of the population. The present study aimed to analyze and map the diffusion and clinical application of MID in different continents around the world. To perform this scoping review, the PRISMA checklist was used, adopting the following: population - dentists; concept - effectiveness of MID; and context - continents. The following databases were used: PubMed, European Archives of Paediatric Dentistry, Scientific Electronic Library, Latin Literature American and Caribbean Association in Health Sciences, and SCOPUS. The following keywords were used in the searches: "pediatric dentistry," "atraumatic restorative treatment," "dental caries," "child health," and "glass ionomer cements" using "and" and "or" combined with "minimal intervention dentistry." Studies published before 2010 as well as theses, dissertations, opinion articles, editorials, and guidelines, were excluded from the study. A total of 160 articles were obtained, and 17 articles were screened and selected for full reading. The analysis of the studies reveals the disparity in the use of minimal intervention techniques among continents due to a lack of knowledge of these techniques or lack of confidence in changing professional approaches, thus emphasizing the need for the dissemination and teaching of MID.

ABSTRACT

This narrative review aimed to provide a comprehensive overview of minimal invasive dentistry (MID) by synthesizing relevant articles obtained from various sources, including electronic databases such as PubMed, SCOPUS, EMBASE, the COCHRANE library, and Science Direct, as well as through manual searches of cross-references and textbooks. The search employed MeSH terms and keywords related to MID, such as "minimally invasive dentistry," "atraumatic restorative treatment (ART)," "MID," and "minimum intervention dentistry." The inclusion criterion was English-language articles published between the years 2000 and June 2023 that aligned with the study objectives. After a thorough assessment of the included articles, 34 high-quality articles were selected for this review. The selected articles elucidate the characteristics of MID, the application of the ART, and the principles of minimum intervention in dentistry. Animal-based studies and narrative reviews on MID were excluded from the analysis. This narrative review serves as a valuable resource for dental professionals, researchers, and educators interested in staying abreast of the latest developments and evidence in the field of MID.

ABSTRACT

The aim of this umbrella review was to evaluate the longevity of glass ionomer cement (GIC) as a restorative material for primary and permanent teeth. Research in the literature was conducted in three databases (MedLine/PubMed, Web of Science, and Scopus). The inclusion criteria were: (1) to be a systematic review of clinical trials that (2) evaluated the clinical longevity of GICs as a restorative material in primary and/or permanent teeth; the exclusion criteria were: (1) not being a systematic review of clinical trials; (2) not evaluating longevity/clinical performance of GICs as a restorative material; and (3) studies of dental restorative materials in teeth with enamel alterations, root caries, and non-carious cervical lesions. Twenty-four eligible articles were identified, and 13 were included. The follow-up periods ranged from 6 months to 6 years. Different types of GICs were evaluated in the included studies: resin-modified glass ionomer cement (RMGIC), compomers, and low- and high-viscosity glass ionomer cement. Some studies compared amalgam and composite resins to GICs regarding longevity/clinical performance. Analyzing the AMSTAR-2 results, none of the articles had positive criteria in all the evaluated requisites, and none of the articles had an a priori design. The criteria considered for the analysis of the risk of bias of the included studies were evaluated through the ROBIS tool, and the results of this analysis showed that seven studies had a low risk of bias; three studies had positive results in all criteria except for one criterion of unclear risk; and two studies showed a high risk of bias. GRADE tool was used to determine the quality of evidence; for the degree of recommendations, all studies were classified as Class II, meaning there was still conflicting evidence on the clinical performance/longevity of GICs and their recommendations compared to other materials. The level of evidence was classified as Level B, meaning that the data were obtained from less robust meta-analyses and single randomized clinical trials. To the best of our knowledge, this is the first umbrella review approaching GIC in permanent teeth. GICs are a good choice in both dentitions, but primary dentition presents more evidence, especially regarding the atraumatic restorative treatment (ART) technique. Within the limitation of this study, it is still questionable if GIC is a good restorative material in the medium/long term for permanent and primary dentition. Many of the included studies presented a high risk of bias and low quality. The techniques, type of GIC, type of cavity, and operator experience highly influence clinical performance. Thus, clinical decision-making should be based on the dental practitioner's ability, each case analysis, and the patient's wishes. More evidence is needed to determine which is the best material for definitive restorations in permanent and primary dentition.

ABSTRACT

O objetivo desta tese foi avaliar a vitalidade pulpar de dentes decíduos com lesão de cárie profunda tratados com duas técnicas restauradoras. A taxa de sobrevivência da restauração foi avaliada como um desfecho secundário. Este volume apresenta um compilado do protocolo de pesquisa e os resultados de ensaio clínico randomizado (Clinicaltrials.gov registration NCT02903979) de não inferioridade com dois braços paralelos relatados pelas recomendações SPIRIT e CONSORT, respectivamente. Crianças de 4 a 8 anos com pelo menos uma lesão cariosa profunda oclusal ou ocluso-proximal em molares decíduos foram selecionadas na clínica odontológica da Universidade Ibirapuera. Cento e oito molares decíduos foram alocados em dois grupos: (1) restauração com cimento de hidróxido de cálcio seguido do cimento de ionômero de vidro de alta viscosidade (CHC + HVGIC) ou (2) restauração com HVGIC. A vitalidade pulpar e a sobrevivência da restauração foram avaliadas em 6, 12 e 24 meses. A análise por intenção de tratar foi usada para a vitalidade pulpar e a análise de sobrevida foi realizada com o método de Kaplan-Meier ( = 5%). Aos 24 meses, 86 restaurações foram avaliadas e 91 foram avaliadas pelo menos uma vez durante o estudo. A perda foi de 20%, e o número de participantes no início e no final do estudo foi semelhante entre os grupos (p = 0,872). Não houve diferença significativa entre os tratamentos restauradores em relação à vitalidade pulpar (CHC + HVGIC = 70% e HVGIC = 68,5%) (OR = 1,09; IC95% = 0,48-2,48). No entanto, as restaurações HVGIC (73%) apresentaram uma taxa de sobrevivência maior do que CHC + HVGIC (50%) (p = 0,021). Na análise de regressão de Cox apenas a variável tratamento apresentou p <0,20. Nesse sentido, a análise ajustada não foi realizada. Os dentes tratados com HVGIC tiveram 65% menos chance de falha do que aqueles tratados com CHC + HVGIC. Assim, pode-se sugerir que a aplicação de CHC é dispensável em lesões profundas de molares decíduos, visto que a longevidade da restauração é menor e a vitalidade pulpar não se altera com sua utilização.

ABSTRACT

High viscosity glass ionomer cement (HVGIC) has been employed as a restorative material for Atraumatic Restorative Treatment (ART). As residual caries persist after caries removal in ART, the antibacterial activity of HVGIC gains importance. Organic and inorganic substances with antibacterial properties have been incorporated into HVGIC over the years, and their effects on the antibacterial and physical properties have been studied. The objective of this paper is to review the various alterations made to HVGIC using organic compounds, their effect on the antibacterial activity, and the physical properties of the cement. Various in vitro investigations have been conducted by adding antiseptics, antibiotics, and naturally occurring antibacterial substances. Most of these compounds render superior antibacterial properties to HVGIC, but higher concentrations affect physical properties in a dose-dependent manner. However, some naturally occurring antibacterial substances, such as chitosan, improve the physical properties of HVGIC, as they enhance cross-linking and polysalt bridging. There is potential for clinical benefits to be gained from the addition of organic antibacterial compounds to HVGIC. In-depth research is required to determine the optimum concentration at which the antibacterial effect is maximum without affecting the physical properties of the cement.

ABSTRACT

AIM: The aim of the study was to evaluate the survival of Class II ART (Atraumatic Restorative Treatment) restorations in primary molars using encapsulated glass ionomer in cavities with and without retentive grooves. A total of 293 Class II restorations were performed on primary molars by three trained operators, using ART hand instruments (SS White/Duflex, Rio de Janeiro, Brazil) and restored with EQUIA Fil (GC Corporation, Tokyo, Japan). One hundred eighty-seven children aged 3 to 7 years (mean age = 5.5) from two public schools located in Lima, Peru, were included in the study. The restorations were performed following the ART protocol, randomising the presence or absence of proximal retentions. Cavity cleaning and restoration times were recorded by the assistant using a digital chronometer. After 6 and 12 months, evaluations occurred following the ART criteria. Data were analysed using the Mann-Whitney, Chisquare and Fisher's exact tests, Kaplan-Meier survival and logarithmic range. The mean dmf-s of the participants was 21.6 (S.D. = 10.2). The mean times to clean the cavity and apply the restorative material were 5.4 and 6.6 minutes, respectively. Success rates after 6 and 12 months for restorations without retentive grooves were 90.3% and 77.2%, respectively; and with retentive grooves 95.9% and 91.8%, respectively. Statistically significant differences were found at the 12-month follow-up (p = 0.001). The proximal retentive grooves increased the survival rate of ART Class II restorations in primary teeth after 12 months of follow-up.

ABSTRACT

OBJECTIVE: Early childhood caries is a common condition that poses a serious risk to children's health because it can progress quickly, resulting in pain, abscesses, and a general decline in health. As a result, invasive therapies are needed, which call for highly skilled personnel. This systematic review of the literature aims to identify the most recent and widely applied early childhood caries (ECC) prevention and treatment approaches. Only substances that act topically and minimally invasive interventions were considered. MATERIALS AND METHODS: The database search was restricted to randomized clinical trials completed within the last five years, specifically those that examined the following procedures: sodium fluoride (NaF) varnish, alternative restorative technique (ART), nano-silver fluoride, silver diamine fluoride, and silver modified atraumatic restorative treatment sealants (SMART). RESULTS: A total of 815 articles were found. After removing duplicates, 584 articles were included, and 567 of them were excluded due to not meeting the predefined inclusion criteria. CONCLUSIONS: Every method considered has been proven to be successful in halting the progression of ECC and is well-liked by patients, even those who are unwilling to cooperate, as well as by parents. The most common unfavorable effect of SDF is irreversible black discoloration in treated tooth surfaces, but this is typically not a problem. They are all low-cost, minimally invasive techniques that might also be widely used in large communities and low socioeconomic settings.

ABSTRACT

Wetting the dentin is critical to atraumatic restorative treatment. The conventional insertion can be challenging when using high-viscosity glass-ionomer cement. This study evaluated the formation of gaps and voids after three insertion methods using micro-CT. Teeth underwent removal of occlusal and proximal caries through the atraumatic restorative treatment technique. Then, they were fixed in an artificial dental arch to simulate the clinical condition and were restored using three insertion methods: conventional, Centrix injection, and double-filling. Previous dentin conditioning procedures, steel matrix and wooden wedge application, and post-insertion procedures (digital compression and surface protection) were the same. The material was inserted using a manual instrument in the conventional technique and was inserted with a syringe in the Centrix injection group. In the double-filling technique, the tooth received a first layer of a flowable ionomer (through modifying the powder/liquid ratio), and a second layer (with standard ratio) was applied before the final set of the first one. A micro-CT unit scanned each tooth before and after restoration. Each cavity was defined as the volume of interest, and the volumes of gaps and voids were calculated. Data were analyzed using one-way ANOVA and Tukey posthoc test (p < .05). Double-filling had improved filling volume with lower values for gap volume, followed by Centrix injection. The conventional technique had the highest gap volume. No statistically significant difference was observed for void volume. Double-filling demonstrated fewer gaps, followed by Centrix injection, which is critical to obtain better adhesive, remineralizing, and antibacterial activities.

ABSTRACT

BACKGROUND: Chemomechanical techniques for caries removal have been introduced to overcome the shortcomings of the conventional rotatory instruments. This study aimed to clinically evaluate the effectiveness of the chemomechanical method of caries removal (Carie-Care™) over mechanical caries removal through the Atraumatic Restorative Technique in pediatric patients. METHODS: A randomized controlled clinical trial was conducted. Fifty children fulfilling inclusion criteria were recruited from the outpatient clinic of Pediatric and Dental Public health department, Faculty of Dentistry, Alexandria University. Fifty open carious primary molars were randomly assigned into 2 equal groups according to the method of caries removal. In Group I (test group), caries was removed using the Carie-Care™ system and in Group II (control group), by using mechanical caries removal through the atraumatic restorative technique. Resin modified glass ionomer was used for teeth restoration, the two techniques were compared in each child according to time taken for caries removal, efficacy of caries removal, pain assessment, and child behavior. RESULTS: The mean time taken for caries removal in the Carie-Care™ treatment group was (575.6 ± 114.8) seconds which was statistically significant higher as compared with the ART treatment group (346.1 ± 97.4) seconds (p < 0.001). The mean score of efficacy in caries removal was (0.6 ± 0.8) in the Carie-Care™ group, and (1.3 ± 0.7) in the ART treatment group. When compared to ART, Carie-Care™ was significantly more efficient in caries removal (p < 0.002). When pain was assessed by the SEM scale, it was observed that the Carie-Care™ caries removal technique showed statistically significantly more comfort during the procedure compared with the ART procedure (p < 0.001).Moreover, children in the Carie-Care™ group enjoyed the process and showed more cooperative behavior when assessed at the end of procedure than those in the ART group with statistically significant difference (p = 0.002). CONCLUSIONS: Removal of carious tissue in primary teeth using Chemomechanical Carie-Care™ gel proved to be more time consuming than ART, but on the other hand it was more efficient, comfortable, and accepted by the pediatric patients.

ABSTRACT

BACKGROUND: In South Africa, an estimated 85% of the population relies on the public sector for oral health services. With poor infrastructure and inadequate personnel, over 80% of children with dental caries remain untreated. To reduce this burden of disease, one key goal is to promote good oral health and address oral diseases through prevention, screening, and treatment among children. While all policies have been proven to be effective in the control and prevention of dental caries, it is unclear which of those strategies provide value for money. This study evaluated five caries preventative strategies in terms of the cost and benefits among South African school children. METHODS: The study uses a hypothetical South African population of school aged learners aged 5-15. The context and insights of the strategies utilized at the schools were informed by data from both grey and published literature. Using Markov modeling techniques, we conducted a cost-effectiveness analysis of Acidulated Phosphate Fluoride (APF) application, atraumatic restorative treatment (ART), sugar-reduction and fissure sealants. Markov model was used to depict the movement of a hypothetical patient cohort between different health states over time. We assessed both health outcomes and costs of various interventions. The health outcome metric was measured as the number of Decayed, Missing, Filled Tooth (DMFT). The net monetary benefit was then used to determine which intervention was most cost-effective. RESULTS: The results showed that school-based caries prevention strategies are cost-effective compared to the status quo of doing nothing. The average cost per learner over the 10-year period ranged from ZAR4380 to approx. ZAR7300 for the interventions considered. The total costs (including screening) associated with the interventions and health outcome (DMFT averted) were: sugar reduction (ZAR91,380, DFMT: 63,762), APF-Gel (ZAR54 million, DMFT: 42,010), tooth brushing (ZAR72.8 million, DMFT: 74,018), fissure sealant (ZAR44.63 million, DMFT: 100,024), and ART (ZAR45 million, DMFT: 144,035). The net monetary benefits achieved for APF-Gel, sugar reduction, tooth brushing, fissure sealant and ART programs were ZAR1.56, ZAR2.45, ZAR2.78, ZAR3.81, and ZAR5.55 billion, respectively. CONCLUSION: Based on the net monetary benefit, ART, fissure sealant and sugar-reduction appear to be the most cost-effective strategies for preventing caries in South Africa. In a resource-scarce setting such as South Africa, where there is no fluoridation of drinking water, this analysis can inform decisions about service packages for oral health.

ABSTRACT

OBJECTIVE: To compare the success of silver diamine fluoride-modified atraumatic restorative technique (SMART) with that of the conventional drill and fill method in restoring carious lesions in primary molars. METHOD: Children (4-8years old) reporting to a tertiary care hospital setting with asymptomatic cavitated dentinal carious lesions in primary molars were randomly allocated to two groups; SMART and Conventional; and subsequently restored with Glass Ionomer Cement (GIC). Follow-up evaluations were carried out by blinded independent evaluator at 6-months intervals to assess the status of restorations. Primary outcome was the success of restorations at 24 months and the secondary outcome was the child's behaviour and acceptance of the treatment at the time of interventions. Two sample Z-test of proportion, logistic regression analysis and Chi-square test were used to compare the outcomes in two groups. RESULTS: A total of 226 children (SMART group, 112 and conventional, 114) were included with 280 and 282 GIC restorations placed by the SMART and the conventional method respectively. At 24-months, 459 (81.6 %) primary molars were available for evaluation. Success rates of restorations was 38.4 % and 45.8 % % in SMART and conventional groups respectively (p = 0.105). The rate of acceptability of treatment in the SMART and conventional group was 79 % and 56 % (p<0.001) respectively. CONCLUSION: There was no significant difference in the success rates of GIC restorations by SMART and conventional technique in carious primary molars at 24 months. SMART was better accepted by children as compared to the conventional restorative technique. CLINICAL SIGNIFICANCE: SMART can be an alternative option to treat the asymptomatic carious lesions in primary molars and is well accepted by children than the conventional drill and fill technique thus implying that it has a useful role in un-cooperative children.

ABSTRACT

Aim: This study evaluated the short-term clinical and microbiological performance of resin-modified glass ionomer cement (RM-GIC) cement containing chlorhexidine (CHX) for atraumatic restorative treatment (ART) in primary teeth. Materials and methods: The clinical trial was conducted in 36 children that received ART in primary molars either with GIC (group I, n = 18) or GIC containing 1.25% CHX (group II, n = 18). The survival rate of restorations was checked 7 days, 3, and 6 months after their application when saliva and biofilm were collected for microbiological assessment of mutans streptococci (MS) counts. Data were analyzed using the Kruskal-Wallis/Mann-Whitney U tests for clinical analysis and microbiological evaluations (p < 0.05). Results: The survival rate of restorations was similar comparing groups I with II. Microbiological analysis showed a significant reduction in MS levels 7 days after the treatment in both saliva and biofilm of children treated with RM-GIC containing CHX (group II); however, MS counts at 3 and 6 months did not differ from the initial counts. Conclusion: A total of 1.25% CHX improved the microbiological properties of GIC in the short term without impairing the clinical performance of ART restorations. Clinical significance: Glass ionomer cement (GIC) containing CHX could be an alternative in ART procedures with the objective of promoting an additional antimicrobial effect, which is interesting for children with high counts of MS during the initial phase of adaptation to dental treatment.

ABSTRACT

PURPOSE: In recent years, minimal intervention procedures (MIPs) for treating dental caries in children have stood out as an innovative method. Nevertheless, the treatment decision should be based on scientific evidence, professional expertise, and parents' preference/acceptance. Evaluating the acceptance of MIPs by parents is an essential factor, but little information is available on what guides this preference. METHODS: This scoping review aims to synthesize the evidence on parents'/caregivers' acceptance of MIP for managing cavitated caries lesions in children. A search was performed in the PubMed, Cochrane Library, Lilacs and Google Scholar databases with no restriction on date or language. RESULTS: A total of 19 articles were selected (6 clinical trials, 1 longitudinal and 12 cross-sectional studies). The application of silver diamino fluoride (SDF) was the most commonly evaluated procedure (n = 17), followed by the atraumatic restorative technique (ART) and the Hall Technique (HT). The acceptance of MIPs ranged from 1.4% to 100%, and the application of SDF was better accepted in posterior teeth and in uncooperative children. ART had better aesthetic acceptance than HT. CONCLUSION: Application of SDF, Hall Technique and ART was well accepted by parents/caregivers. However, a gap remains in the literature regarding the acceptance of other procedures. Therefore, further studies in this area will contribute toward a better understanding of the opinion of parents/caregivers, and thus improve caries lesion management in children.

Resumo O molhamento da dentina parcialmente desmineralizada no fundo da cavidade dentária é fundamental para o sucesso do tratamento restaurador atraumático. No entanto, o método de inserção convencional pode ser desafiador ao usar cimento de ionômero de vidro de alta viscosidade. Este estudo avaliou a formação de gaps e vazios internos após três métodos de inserção de cimento de ionômero de vidro de alta viscosidade usando micro-CT. Dez terceiros molares foram submetidos à remoção de cárie oclusal através da técnica de tratamento restaurador atraumático e complementação proximal (com ou sem lesão pré-existente). Em seguida, foram fixados em uma arcada dentária artificial para simular a condição clínica. Os dentes foram restaurados usando a técnica de tratamento restaurador atraumático com três métodos de inserção: convencional, injeção Centrix e dupla inserção. Os procedimentos anteriores de condicionamento dentinário, inserção de matriz de aço, aplicação de cunha de madeira e procedimentos pós-inserção do material (como compressão digital e proteção de superfície) foram os mesmos para os três grupos testados. O material foi inserido com instrumento manual na técnica convencional, seguindo a metodologia clássica do tratamento restaurador atraumático. O material foi inserido com um dispositivo desenvolvido especificamente para esse fim na técnica de inserção com seringa tipo Centrix. Na técnica de dupla obturação, o dente recebeu uma primeira camada do cimento de ionômero de vidro mais fluido (obtido através da modificação da relação pó/líquido), e uma segunda camada (com relação pó/líquido padrão) foi aplicada antes da presa final da primeira. Um micro-CT escaneou cada dente antes e depois da restauração. Cada cavidade foi definida como o volume de interesse, e os volumes de gaps e vazios foram calculados. Os dados foram analisados por ANOVA one-way e teste post-hoc de Tukey com nível de significância de 5%. A dupla inserção melhorou significativamente o volume de preenchimento com valores percentuais mais baixos para o volume do gap, seguido pela injeção com seringa tipo Centrix. A técnica convencional apresentou o maior percentual de volume de gap. Nenhuma diferença estatisticamente significativa foi observada para o volume de vazios internos. O grupo de dupla inserção demonstrou menor formação de gaps, seguido pelo grupo de injeção com seringa tipo Centrix, que é fundamental para obter melhores atividades adesivas, remineralizantes e antibacterianas.

ABSTRACT

Objectives: The aim of the study was to evaluate the clinical and radiographic success of the Hall technique (HT) and atraumatic restorative treatment (ART) restorations using high-viscosity glass-ionomer cement for the management of occlusal carious lesions in primary molars. Materials and Methods: This randomized clinical study observed 40 children (aged 5-6 years). For each child, one tooth was treated with HT and one with ART. The primary outcome measures for HT restorations were successful, minor, and major failure rates. Clinical evaluations of ART restorations were performed according to the modified United States Public Health Service criteria during 18-month follow-up. McNemar test was used for statistical analysis. Results: Thirty of 40 (75%) participants returned for 18 months of follow-up. In the clinical evaluations of teeth that were treated with HT, the patients did not have complaints of pain or other symptoms, all crowns remained in the oral cavity, the gums were healthy, and the teeth were functional in all evaluations. At the end of the 18-month follow-up, the surface texture and marginal integrity criteria of ART restorations were recorded as 26.7% and 33.3%, respectively. In the radiographic evaluation of 30 patients treated with ART and HT, all restorations were considered successful. Conclusions: The 18-month clinical and radiographic results after treatments applied to single-surface cavities in anxious children showed that both treatment methods were successful.

ABSTRACT

OBJECTIVES: This study: 1) aims to test the mechanical and antibacterial properties of fluorinated graphene strengthened glass ionomer materials (FG/GICs); 2) aims to investigate the effects of thermo-cycling on (FG/GICs). MATERIALS AND METHODS: Fluorinated graphene (FG) with bright white color was prepared from fluorinated graphite (SIGMA Aldrich), using modified Hummer's method, to be added to conventional glass ionomer cements (GICs). In addition to a control group (group 1), experimentally modified GICs were prepared by adding FG to the conventional glass ionomer powder with three different weight ratios; (group 2, 1 wt %; group 3, 2.5 wt %; and group 4, 5 wt %) using mechanical blending method. Experimental groups of the specimens (n = 240) were divided, for each concentration (n = 120) half of the specimens were subjected to thermo-cycling. Hardness, compressive strength, and antibacterial activity of (FG/GICs) were measured with and without thermo-cycling. Compressive strength was measured by a universal testing machine, hardness was measured using a Vickers micro-hardness tester, and antibacterial effects against staphylococcus aureus and streptococcus mutans were tested by the pellicle sticking method. For statistical analysis, numerical data were explored for normality and variance homogeneity using Shapiro-Wilk and Leven's tests respectively. RESULTS: The prepared (FG/GICs) showed an increase in hardness in group 4 (p < 0.001). Groups 3 and 4 gave the highest compressive strength values with no significant difference between them (p < 0.001). Groups 2, 3, and 4 showed improved antibacterial activity with no statistical difference between them (p > 0.001). Results after thermo-cycling showed significantly decreased hardness, and compressive strength values (p < 0.001), however, the results of antibacterial activity against streptococcus mutans showed no statistical difference after thermo-cycling (group 2, p = 0.05; group 3, p = 0.18; group 4, p = 0.26). The same results were observed for antibacterial activity against staphylococcus aureus (p = 0.92, p = 0.14, and p = 0.48 respectively). CONCLUSION: FG can be considered a promising additive to GICs to promote its anti-cariogenic effects, however, these antibacterial effects are only useful in the short term, as aging adversely affected their mechanical properties. The 2.5 wt % FG/GICs is suggested to be the most encouraging, as after aging, it represented the highest compressive strength among all groups, while its hardness values were at least comparable to that of conventional glass ionomer. CLINICAL SIGNIFICANCE: FG/GICs can be considered an anti-cariogenic restoration in temporary restorative interventions, as in certain cases in deciduous teeth where considerable esthetics may be required, especially those with difficult moisture control, where neither resin composite restorations nor amalgam restorations will be indicated. It can also be used for patients with high caries index or in atraumatic restorative treatment (ART) in low-income countries.

ABSTRACT

OBJECTIVE: Several extrusion techniques have been described to restore teeth with insufficient coronal tooth structure and to avoid their extraction. Still, there is little evidence for a treatment concept combining surgical extrusion using an atraumatic axial extraction system. MATERIALS AND METHODS: A total of nine patients, each with an iso- or subgingival fractured tooth, were retrospectively examined. Treatment of the damaged tooth comprised an atraumatic forced surgical extrusion performed with an axial tooth extraction system and a more coronal positioning within the socket. The teeth were initially splinted and subsequently restored. The follow-up period was up to 57.1 months and averaged 36.5 (SD: ±13.5) months. RESULTS: All nine teeth were still in situ, without signs of inflammation. During the period of the provisional restoration, six prosthetic complications occurred, which were resolved with little effort, whereas, success rate for the definitive restoration was 100%. No biological complications were observed concerning the root apex or soft tissue. The radiographically measured mean extrusion distance was 3.4 (SD: ±1.0) mm, so that a sufficient prosthetic ferrule could be reestablished. CONCLUSIONS: Surgical extrusions using an axial tooth extraction system demonstrate low biological and prosthetic complications rates over observation time. CLINICAL SIGNIFICANCE: The presented extrusion approach preserves soft and hard tissue and is an efficient treatment option for severely destroyed teeth. Saving hopeless teeth by this relatively predictable and feasible procedure has hardly any disadvantages for patients, and in case of failure, an implant or fixed partial denture are still an option.

ABSTRACT

O objetivo do presente estudo foi apresentar um relato de experiência com utilização de Odontologia Minimamente Invasiva em intervenção, tratamento e prevenção de cárie em crianças de escola pública por meio da integração de uma Instituição de Ensino Superior com o sistema público de saúde e comunidade. Para tal ação, a intervenção foi dividida em: Fase 1 -aplicação funcional das diretrizes de atendimento odontológico seguindo o Tratamento Restaurador Atraumático (ART) e Fase 2 -análise crítica da efetividade das ações da fase 1, para potencial reprodução sob contexto de retomada das atividades escolares presenciais. Na Fase 1, graduandos do último período de Odontologia de uma universidade estadual realizaram o levantamento clínico e atendimento com a técnica do ART em 275 pacientes provenientes de uma escola da rede pública municipal de ensino fundamental, em escolares na faixa etária de 6 a 15 anos de idade. A partir da Fase 2 (Análise crítica de efetividade de ações) foi possível reconhecer, por meio de uma análise descritiva das experiências vivenciadas e da avaliação do resultado do primeiro controle realizado dois meses após realização ART, que essa atividade foi efetivamente um modelo desucesso na integração ensino-serviço, capaz de exemplificar uma experiência potencialmente significativa para emprego em contextos de retomada das atividades escolares presenciais, minimizando os problemas gerados pelo distanciamento social e interrupção temporária das consultas eletivas em Odontologia. A integração ensino-serviço com a ação realizada promoveu a qualidade de vida e redução da vulnerabilidade e riscos à saúde bucal (AU).

The aims of this study were to present an experience case report on the use of Minimally Invasive Dentistry in the intervention, treatment, and prevention of dental cavities in children attending public schools through the integration of a Higher Education Institution along with the Brazilian public health system known as Unified Health System, and the community. For this action, the intervention was dividedinto: Phase 1 -application of the dental care guidelines following the Atraumatic Restorative Treatment (ART) and Phase 2 -critical analysis of the effectiveness of phase 1 actions, for potential reproduction under the context of resumption of face-to-face school activities after COVID-19 pandemic. During Phase 1, last period undergraduates of Dentistry from a state university carried out a clinical survey with the ART technique in 275 patients from a public municipal elementary school, in schoolchildrenaged 6 to 15 years old. Based on Phase 2 findings, it was possible to recognize, through a descriptive analysis of the experiences lived and the evaluation of the first follow-up, carried out two months after performing ART, that this initiative was highly successful. It served as a valuable model in the context of resuming face-to-face school activities, mitigating the challenges caused by social distancing measures and the temporary suspension of elective dental appointments due to the pandemic. The education-service integration with the implemented action promoted a better quality of life and reduced vulnerability and risks to oral health (AU).

ABSTRACT

Introdução: a Hipomineralização Molar Incisivo (HMI) é um defeito qualitativo de desenvolvimento de esmalte que pode ocasionar fraturas pós-eruptivas (FPE), lesões de cárie e sensibilidade. Objetivo: relatar o tratamento de HMI severa através da cimentação de bandas ortodônticas para preservação da estrutura dentária em primeiros molares permanentes inferiores com FPE. Relato do caso: criança do sexo feminino, 10 anos de idade, apresentou-se com queixa de hipersensibilidade e fratura dentária associada à restauração prévia. Clinicamente, observou-se presença de HMI severa, com FPE associada à lesão de cárie em dentina nas superfícies oclusal e vestibular do dente 36 e restauração insatisfatória com cimento de ionômero de vidro (CIV) na superfície vestibular do dente 46 que apresentava opacidades demarcadas branco-creme. Radiograficamente, observou-se ausência de comprometimento pulpar. Após manejo por meio de abordagens não-invasivas (controle de biofilme e dieta e aplicação de verniz fluoretado), o tratamento proposto foi a cimentação de banda ortodôntica com CIV modificado por resina (Riva Light Cure®, SDI) nos dentes 36 e 46 para maior longevidade das restaurações. O tratamento restaurador atraumático (TRA) foi realizado no dente 36 previamente à cimentação da banda ortodôntica. Resultados: após o tratamento, a criança não relatou dor ou desconforto e as restaurações mantiveram-se intactas. A mãe da criança foi orientada quanto à importância de acompanhamento periódico a cada 4 meses. Conclusão: a cimentação das bandas ortodônticas com CIV possibilitou o manejo conservador de molares permanentes com HMI severa, com manutenção de sua funcionalidade oclusal, saúde pulpar e gengival, proporcionando melhor qualidade de vida à paciente.


Introduction: molar Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that can cause posteruptive enamel breakdown (PEB), caries lesions, and sensitivity. Objective: to report the treatment of a child with severe MIH through the cementation of orthodontic bands in lower first permanent molars with PEB to preserve tooth structure. Case report: female child, 10 years old, presenting hypersensitivity complaints and tooth fracture associated with previous restoration. Severe MIH was observed, with PEB associated with dentin caries on the occlusal and buccal surfaces of tooth #36 and unsatisfactory glass ionomer cement (GIC) restoration on the buccal surface of tooth #46 which had creamy-white marked opacities. There was no pulp involvement radiographically. After management through non-invasive approaches (biofilm and diet control and application of fluoride varnish), the proposed treatment was the cementation of an orthodontic band with resin-modified GIC (Riva Light Cure®, SDI) on teeth #36 and #46 to long-term lifespan restorations. Atraumatic restorative treatment (ART) was performed on tooth #36 prior to the cementation of the orthodontic band. Results: after treatment, the child did not report pain or discomfort and the restorations remained intact. The child's mother was instructed about the importance of periodic follow-up visits every 4 months. Conclusion: the cementation of orthodontic bands with GIC allowed the conservative management of permanent molars with severe MIH, maintaining their functional occlusion, pulpal and gingival health, providing a better quality of life to the patient.
