RESUMO

The COVID-19 pandemic resulted in severe limitation and closure of dental practices in many countries. Outside of the acute (peak) phases of the disease, dentistry has begun to be practised again. However, there is emerging evidence that SARS-CoV-2 can be transmitted via airborne routes, carrying implications for dental procedures that produce aerosol. At the time of writing, additional precautions are required when a procedure considered to generate aerosol is undertaken.This paper aims to present evidence-based treatments that remove or reduce the generation of aerosols during the management of carious lesions. It maps aerosol generating procedures (AGPs), where possible, to alternative non-AGPs or low AGPs. This risk reduction approach overcomes the less favourable outcomes associated with temporary solutions or extraction-only approaches. Even if this risk reduction approach for aerosol generation becomes unnecessary in the future, these procedures are not only suitable but desirable for use as part of general dental care post-COVID-19.

RESUMO

AIM: To compare and evaluate the caries preventive effectiveness of resin infiltrant (ICON), casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) (GC Tooth Mousse), and nanohydroxyapatite (Aclaim) on incipient enamel lesions. MATERIALS AND METHODS: A total of 60 human maxillary incisors extracted for periodontal reasons were included in this study. The sectioning was done at the middle third region of the crown for the 60 samples with approximate dimensions of 5 × 5 × 5 mm). In order to create the artificial enamel lesions, the samples were demineralized by placing in a beaker containing the prepared demineralizing solution for 14 days. The study samples were then divided into four groups that are resin infiltrant (group I), CPP-ACP (group II), nanohydroxyapatite (group III), and control (group IV) with 15 enamel samples in each group. The caries preventive efficacy of each group was evaluated using a confocal laser scanning microscope. RESULTS: The mean values after demineralization of enamel samples in demineralizing solution are 245 µm for resin infiltrant (group I), 246 µm for CPP-ACP (group II), 250 µm for nanohydroxyapatite (group III), and 247 µm for control (group IV). After remineralizing the enamel samples for a period of 30 days, the results are group I (resin infiltrant) 158 µm > group II (CPP-ACP) 28.8µm ≥ group III (nanohydroxyapatite) 26.3 µm. After subjecting it to demineralizing solution again for 14 days, the amount of material that was resistant to acid attack was group I (resin infiltrant) 114 µm (72%) > group III (CPP-ACP) 16.4 µm (57%) ≥ group III (nanohydroxyapatite) 13.8 µm (50%). The untreated control group showed increased progression of lesion and least resistance to acid challenge. CONCLUSION: Based on the results from this in vitro study, it can be concluded that when compared to the two remineralizing agents the resin infiltrant showed better caries preventive effectiveness. CLINICAL SIGNIFICANCE: Resin infiltrants have a favorable penetration potential in subsurface or incipient enamel lesions.

RESUMO

AIM: This literature review aims to update the evidence for prevention of white spot lesion (WSL) using orthodontic sealants among patients with fixed orthodontic appliances. BACKGROUND: As a major issue among orthodontists, prolonged treatment duration increases the risk of plaque development around orthodontic brackets and bands. In consequence, this can lead to heightened risk for caries development and higher possibility of WSL development around fixed orthodontic brackets. RESULTS: Increased prevalence of WSLs generally occurs during orthodontic treatment. This review explored various products of orthodontic sealants used to prevent WSL. Orthodontic sealants do not require patient compliance and thus will further lessen the burden among orthodontists as well as support enamel surface for a long period of time during treatment. Certain factors, however, are considered important in the efficacy of these sealants, such as antibacterial activity, color stability, resistance to acid and brush abrasion, and their effect on shear bond strength (SBS). CONCLUSION: The review showed that the use of orthodontic sealants in preventing WSLs during and after fixed orthodontic treatment is significantly effective. However, the bioactive glass is deemed more effective against WSL development due to its ability to immediately repair enamel surface, low cytotoxicity, and high biocompatibility. Moreover, clinical studies on bioactive glass are still needed to determine its acceptability among patients with fixed orthodontic appliance. CLINICAL SIGNIFICANCE: Development of WSL around the orthodontic brackets during treatment is a difficult task among orthodontists. As such, this review explored various strategies to effectively combat WSL development for good oral health and esthetics during orthodontic treatment.

RESUMO

Purpose: Dental caries is a chronic childhood disease disproportionately affecting children from low socioeconomic backgrounds. Free preventive oral health events sponsored by dental organizations are frequently under enrolled. The purpose of this study was to explore parental perceptions and barriers to participation in preventive dental care programs for their children.Methods: The transtheoretical model and social cognitive theory were used to design this qualitative case study. Open-ended questions were used to interview 20 purposefully sampled participants regarding their perceptions of free preventive dental care programs. Interviews were audio recorded, data were transcribed verbatim, coded, and analyzed thematically until saturation.Results: Two male and 18 female parents ranging in age from 22 to 49 years, with at least one child enrolled in a Title 1 New York City public elementary school, agreed to participate. Nine themes emerged from the data addressing the primary research question on the perceived barriers preventing parents from allowing their children to attend a free preventative dental care program. The themes included too busy, afraid, lack of trust, cultural differences, lack of awareness of the program, cost of care, money, negative childhood experiences and lack of dental insurance.Conclusion: Results from this study demonstrate the need to understand barriers to full enrollment in preventive oral health programs. Particular attention should be given to cultural differences between the program providers and the local residents. Preventative oral health program organizers need to explore multiple communication options to notify parents of upcoming programs.

RESUMO

PURPOSE OF THE STUDY: The aim of the work is a spectroscopic investigation and comparison of the molecular composition of dentine and gingival fluids as well as of their diagnostic potential for the preventive screening of dentin caries. MATERIAL AND METHODS: Applying infrared spectroscopy including synchrotron radiation the samples of biological fluids taken from the oral cavity (dentine fluid, fluid from the gingival sulcus and blood) were studied for the patients with the progressive dentine caries. The part of this research was undertaken with the infrared microspectroscopy beamline at the Australian Synchrotron. RESULTS: Dentine and gingival fluids were shown to have no less complicated composition than the blood serum. Having all this in mind, in spite that these two fluids are derivatives of the blood serum, and a majority of the molecular groups observed in all of the three fluids can be detected in their IR-spectra, it follows that there is a number of signature modes that are in fact present in the IR spectra of only dentine and gingival fluids. This fact indicates at the molecular exchange between them under certain conditions. It means the high diagnostic potential in the study of the pathologic processes occurring in the oral fluid of a human. We have observed and fixed an increase of thiocyanates and esters in the samples of both dentine and gingival fluids under the development of dentin caries. CONCLUSION: Utilization of the gingival fluid for screening taking into account that its sampling is not such a complicated challenge as dentine fluid sampling will promote a transition to the personalized medicine, the development of high-technology healthcare and technology of the health preservation as a whole.

RESUMO

Design A single-blinded, randomised controlled trial. The experimental group received 24 personalised text messages each week, disseminating tailored preventive advice using the multifactorial model for individual caries risk assessment: Cariogram. The same frequency of text messaging was delivered to the control group; however, these were non-personalised messages and did not factor the Cariogram.Sample selection One hundred and ninety-one participants were assessed for eligibility by eight calibrated, volunteer dental practitioners in County Cork, Ireland. Six different inclusion criteria were detailed, including the requirement for medical card holders, serving as an indicator for economically underprivileged status. Other criteria included: aged between 19-70 years; competent with text messaging services; have a minimum of 20 teeth present; not pregnant; and prepared to give consent. Failure to return a baseline food diary or possess a mobile phone saw the exclusion of 20 participants. Following stratified and blocked randomisation, 85 and 86 participants were allocated in the test and control group, respectively. The study received ethical approval by the Clinical Research Ethics Committee of the Cork Teaching Hospitals.Data analysis One hundred and eleven participants attended the follow-up examination, 26 weeks after randomisation, where the 'chance of avoiding new cavities' was determined as a numerical index for caries risk. The secondary aim was to measure individual changes to seven Cariogram risk factors between the baseline assessment and the re-examination. The ANCOVA intention-to-threat (ITT) protocol and the per-protocol method were adhered to for analyses of outcome measures. Statistical analysis was performed using SAS 9.4, in adherence to a pre-defined significance level of 5% (two-sided).Results Both analytic techniques confirmed no statistically significant difference (p >0.05) between the groups regarding the 'chance of avoiding new cavities'. Of the risk parameters assessed, only saliva secretion demonstrated a positive effect in the intervention group (p = 0.036, OR = 0.3, 95% CI = 0.1, 0.9). Predictive modelling techniques were not reliable due to the limited sample size of per-protocol analysis.Conclusions The failure to conclude statistical significance between the groups validates the null hypothesis. Accordingly, no difference can be established between the personalised nor non-personalised mobile text messaging intervention on the caries risk of underprivileged adults in Ireland. The authors address the value of further studies exploring the potential for caries risk reduction through mobile phone communications.

RESUMO

This study investigated the caries-preventive effect of 445 nm laser radiation in combination with fluoride on the prevention of white spot lesions. Previously, several studies have indicated the ability of 488 nm argon ion laser irradiation to reduce early enamel demineralization. A diode laser (445 nm) could be an alternative technology for possible caries-preventive potential. Each sample of a group of seventeen caries-free bovine teeth was treated in four different ways on four different zones of the labial surface: control/no treatment (C), laser irradiation only (L) (0.3 W, 60 s and applied dose of 90 J/cm2), amine fluoride application only (10,000 ppm and pH 3.9) (F), and amine fluoride application followed by laser irradiation (FL). After treatment, the teeth were subjected to a demineralization solution (pH 4.3 for 48 h at 37 °C) to induce subsurface lesions. After sectioning, the teeth were examined by light microscopy. Three teeth were analyzed by scanning electron microscopy (SEM). The depths of the subsurface lesions in the C, L, F, and FL groups were 103.01 (± 13.04), 96.99 (± 14.51), 42.59 (± 17.13), and 24.35 (± 11.38) µm, respectively. The pairwise group comparison showed the following results: p < 0.001 for FL versus C, FL versus L, F versus C, and F versus L, p = 0.019 for FL versus F and p = 0.930 for L versus C. The SEM micrographs support the light-microscopic examination. The results of the current study have shown that using relatively low irradiation settings of 445 nm laser on fluoridated enamel may be effective for prevention of white spot lesions.

RESUMO

The scoping review aimed to examine the evidence on the role of synbiotics in caries prevention. PubMed, SCOPUS, and Web of Science databases search were performed. Any in vitro study, clinical trial, systematic review with/without meta-analysis, umbrella review/meta-evaluation, narrative review addressing the role of synbiotics in caries prevention were included in the scoping review. Data were extracted from the included studies using pre-approved registered protocol. Twenty-eight records were identified, of which 5 in vitro studies, 1 quasi-experimental clinical trial and 1 narrative review were included in the present review. No controlled clinical trials or systematic reviews on the role of synbiotics in caries prevention could be identified. Except 1, all in vitro studies examined the combined effect of saccharides and lactobacilli spp. as potential synbiotics on the growth of Streptococcus mutans. However, the proposed synbiotics in 4 in vitro studies either did not qualify or remained ambiguous of its eligibility as a potential synbiotic for caries prevention. One recent in vitro study explored the possibility of L-arginine and Lactobacillus rhamnosus GG synbiotic for caries prevention. The quasi-experimental clinical study without a control arm did not explicitly mention the intervention composition and thus, its synbiotic potential remains unclear. A narrative review highlighted the potential of combining arginine (prebiotic) with arginolytic bacteria (probiotic) as a synbiotic, which appears promising for caries prevention. The eligibility of the proposed synbiotics as a true synbiotic needs to be carefully addressed. Due to a lack of controlled clinical studies on synbiotics for caries prevention, evidence on their caries-preventive potential is weak. Future studies are needed to examine the combination of amino acids (esp. arginine) with probiotics as a potential synbiotic against cariogenic pathogens.

RESUMO

As a result of aging populations, in the future, dental practitioners will be caring for more older adults than ever before. These older adults, especially in developed countries, will demand a greater number of dental services, driven by increased tooth retention and an expectation of excellent oral healthcare throughout the life course. Further, the global rise in the prevalence and incidence of chronic diseases will increase the risk and/or severity of oral diseases and add a layer of complexity to the management of oral diseases in older adults. More older adults will be at a higher risk of periodontal disease and root caries as a result of reduced tooth loss and edentulism. This article reviews information on periodontitis and root caries, oral diseases which reflect the cumulative risk of the individual, and which are best addressed through prevention. Oral healthcare providers must embrace the concept of lifelong emphasis on prevention, as well as participation as active members of a healthcare team which provides healthcare for older adults in various settings (eg, hospital/clinic-based care, community-based settings, and long-term care facilities). National guidelines that address oral health are being considered by some countries, and if these are implemented they will increase the accessibility to oral health for older adults. In parallel to this, revisions of existing older adult insurance schemes (eg, the inclusion of routine oral healthcare in the US Medicare program) would promote the maintenance of a functional dentition that is pain-free and conducive to general health. The opportunity exists to implement a holistic approach to oral health that will align oral health with general health and emphasize that true health can only be achieved with the inclusion of oral health.

RESUMO

PURPOSE: The first aim of this paper is to provide dental professionals caring for children and adolescents during and after the COVID-19 pandemic with a reference to international dental guidelines. The second aim is to suggest minimally invasive treatment alternatives for caries management, minimising the risk of viral cross-infection and offering a safer clinical environment. METHODS: An evidence-based pertinent literature search of different electronic databases was performed in addition to leading global dental authorities, royal colleges, and programmes. RESULTS: All guidelines released in response to COVID-19 centred around minimising Aerosol Generating Procedures (AGP) impacting the provision of regular dental treatment of paediatric patients. There was an emphasis on triaging and only treating emergency and urgent cases. Special attention was given to medically compromised children in the guidelines. Detailed guidelines for the dental environment and equipment were given. This paper also summarised the relevant evidence-based guidelines for the use of non-invasive and minimally invasive caries management techniques. CONCLUSION:  Specific recommendations for dental management of paediatric patients during and in the post-COVID-19 era are suggested. Minimisation of AGP procedures, and case-based selection of biological, non-invasive or minimally invasive methods are recommended.

RESUMO

OBJECTIVE: To investigate the effect of a 5% sodium fluoride varnish with functionalized tri-calcium phosphate (fTCP) on post-orthodontic white spot lesions. A secondary aim was to study if the patients and their clinicians perceived clinical improvements. METHOD AND MATERIALS: Fifty-nine patients with at least two visible WSLs on their maxillary incisors, canines, or first premolars present at the debonding of fixed appliances (baseline) were enrolled and assigned to a Varnish group (Clinpro White Varnish, 3M Espe) receiving topical applications at baseline and after 8 weeks, or a Control group treated with a fluoride-free mock product. The primary endpoint was white spot lesion appearance after 16 weeks, assessed from photographs using the modified ICDAS white spot lesion score (0 to 3). The patients and the dental examiners rated the white spot lesions subjectively with aid of a visual analog scale. RESULTS: Fifty-seven patients completed the study. After 16 weeks, 62% of the white spot lesions in the Varnish group were completely reversed (score 0) compared to 39% in the Control group. The treatment effect was statistically significant (OR 0.22; 95% CI 0.08 to 0.59, P = .003) after adjusting for baseline oral hygiene index and type of tooth. A significant correlation (P < .05) was observed between patients' and orthodontists' perception of the lesions. CONCLUSION: The 5% sodium fluoride varnish with fTCP appeared clinically effective in reversing post-orthodontic white spot lesions 16 weeks after debonding. The patients and the clinicians agreed on the obtained esthetic improvements.

RESUMO

OBJECTIVE To discuss the negative and positive concepts of liberty and postulate its interdependent and complementary relationship in the evaluation of public policy intersectoral actions, taking water fluoridation as a case. METHOD To describe scopes and limits regarding 1950s Isaiah Berlin's distinction, showing its validity in facing the harmful effects of an uncontrolled market economy and an autocratic political regime. RESULTS Both the rights that protect citizens against a powerful state and the rights that protect the state against powerful citizens were equally acknowledged as crucial. CONCLUSION We argued that, in a context in which negative and positive liberties are balanced, regulatory policies have double meaning. Thus, there should be a balance between the establishment of necessary rules for social protection and limits for them not to violate individuals' rights.

RESUMO

Poor oral hygiene seems to be the norm in children and teenagers with Down Syndrome (DS). Advances in design and types of toothbrushes may improve biofilm control. This randomized, single-blind, crossover clinical trial evaluated the effectiveness of electric toothbrushes regarding mechanical control of biofilm in children and teenagers with DS and their cooperation. Twenty-nine participants with DS, aged 6 to 14 years, used both types of toothbrushes: electric (ET) and manual (MT). The order of use of the different types of toothbrushes was randomly defined, including a 7-day period with each type with 7-day washout period in between. The Turesky-Quigley-Hein biofilm index was used before and after brushing to assess the effectiveness of the technique. Frankl's behavioral scale was used during toothbrushing to assess the participants' cooperation. Paired T-test, Mann Whitney, Chi-square, and Fisher's Exact tests were applied, with a significance level of 5%. The quantity of dental biofilm was significantly reduced after both brushing techniques (p < 0.001). However, no significant difference was found in total biofilm (ET: 0.73 ± 0.36; MT: 0.73 ± 0.34; p = 0.985) or % biofilm reduction (ET: 72.22%; MT: 70.96%; p = 0.762) after brushing between techniques or in % biofilm reduction between toothbrushes of age groups (6 -9 years, p = 0.919; 10-14 years, p = 0.671). Participants showed similar cooperation level with the two types of toothbrush (p = 1.000). The use of electric or manual toothbrush had no effect on the quantity of dental biofilm removed in children and teenagers with DS, nor did it influence their cooperation during the procedure.

RESUMO

OBJECTIVES: Oral health can affect quality of life in all course of life, which is a key factor of general health. Dental caries, periodontitis and oral cancer are of the highest burden of oral diseases. Rising prevalence of soft drinks and alcoholic beverages consumption due to easy access and socio-demographic altering has increased the concerns on oral health. In this review our purpose was to show effects of the most consumed beverages on oral health in people older than 15 years. METHODS: The review was based on papers published in last 10 years, searched with combined key words related to types of drinks and specific oral health problems. We included 4 older studies due to lack of newer studies on subjected topics. RESULTS: Sugar-free soft drinks are found less cariogenic and erosive than regular versions in limited number of studies. Alcohol consumption is shown as one of the risk factors of prevalence and severity of periodontitis and is proven to have synergistic effects along with tobacco on oral cancer risk. Consumption of soft drinks and alcoholic beverages was related with tooth loss whether dental caries or periodontal diseases. CONCLUSION: There is good evidence for association between soft drinks and oral health problems, but still no clear answer exists about strength of association between sugar-free soft drinks and dental caries. Also the knowledge about influence of alcohol is inadequate. Since consuming style affects erosive potential of drinks manufacturers should be required to add some recommendations on labels about drinking style.

RESUMO

The aim of this study was to analyze legislative proceedings on fluoridation policies in Brazil from 1963 to 2019. The theoretical reference was Pierre Bourdieu. A document search was performed on legislative proceedings that address the theme of fluoridation in Brazil as a public health measure and the discussions in the National Congress. The sources for the article were the official websites of the Chamber of Deputies (lower house) and the Senate to consult the legislative acts related to fluoridation in Brazil. The study showed that from 1963 to 2001 and in 2017 there was a dispute between fluoridation methods for the water supply, mineral water, and table salt fluoridation. However, there was a crosscutting understanding of the importance and benefits of systemic fluoride use. From 2003 to 2013, the bills challenged the use of systemic fluoride, proposing its use only in topical applications. In the 1960s, 1970, and 2017, the legislative bills showed a closer approach to the scientific field and were submitted by opposition members of Congress. Unlike the issue of water fluoridation, of the 6 legislative bills in favor of salt fluoridation, only one was drafted by a health professional da health, and only two by legislators from the Southeast region. There were more bills by legislators from the Central and Northeast. Those with training in health exhibited positions in defense of some method of systemic fluoridation. The analysis allowed interpreting the historical process of developing the response to the caries problem and the different strategies employed in this process.

RESUMO

Objective: The aim of this concise review is to summarize the use of silver nanomaterials for caries prevention. Methods: Two researchers independently performed a literature search of publications in English using Embase, Medline, PubMed, and Scopus databases. The keywords used were (silver nanoparticles OR AgNPs OR nano silver OR nano-silver) AND (caries OR tooth decay OR remineralisation OR remineralization). They screened the title and abstract to identify potentially eligible publications. They then retrieved the full texts of the identified publications to select original research reporting silver nanomaterials for caries prevention. Results: The search identified 376 publications, and 66 articles were included in this study. The silver nanomaterials studied were categorized as resin with silver nanoparticles (n=31), silver nanoparticles (n=21), glass ionomer cement with silver nanoparticles (n=7), and nano silver fluoride (n=7). Most (59/66, 89%) studies investigated the antibacterial properties, and they all found that silver nanomaterials inhibited the adhesion and growth of cariogenic bacteria, mainly Streptococcus mutans. Although silver nanomaterials were used as anti-caries agents, only 11 (11/66, 17%) studies reported the effects of nanomaterials on the mineral content of teeth. Eight of them are laboratory studies, and they found that silver nanomaterials prevented the demineralization of enamel and dentin under an acid or cariogenic biofilm challenge. The remaining three are clinical trials that reported that silver nanomaterials prevented and arrested caries in children. Conclusion: Silver nanoparticles have been used alone or with resin, glass ionomer, or fluoride for caries prevention. Silver nanomaterials inhibit the adhesion and growth of cariogenic bacteria. They also impede the demineralization of enamel and dentin.

RESUMO

In this study, we focus on the antimicrobial properties of tempeh, a soybean fermented food, against oral bacteria. Tempeh showed antimicrobial activity against dental caries pathogenic bacterium Streptococcus mutans at a final concentration of 1 mg/mL. An antimicrobial substance contained in tempeh was present in the 100 kDa or greater fraction generated by ultrafiltration, but it was found not to be proteinaceous by native-PAGE, SDS-PAGE and protein degradation tests. Next, when the fraction was purified with an ODS column, the 80% and 100% methanol eluates showed antimicrobial activity against S. mutans. The 100% methanol eluate was further subjected to a 2nd column purification, and isolation of the target was confirmed by HPLC. When the isolated material was analyzed by ESI-MS, the m/z was 279.234. Further analysis by Raman spectroscopy revealed a peak similar to linoleic acid. This substance also possessed antimicrobial properties equivalent to linoleic acid.

RESUMO

Background: The prevalence of white spot lesions/tooth demineralization during orthodontic fixed appliance therapy ranges widely from 2 to 96% of patients. The purpose of this study was to evaluate measures used by orthodontists practicing in Nigeria to manage demineralization during and after fixed orthodontic treatment and how it compares with the available evidence-based information. Method: Study group comprised of 60 practitioners (21 orthodontists and 39 orthodontic residents) in Nigeria. Self-administered questionnaires were used to obtain information on the measures they use to prevent the occurrence of demineralization at the onset and during orthodontic treatment, as well as the management of its occurrence at treatment completion. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 17.0. Descriptive statistics were used. Level of significance was set at P < 0.05. Results: Responses obtained showed that 96.7% of orthodontic practitioners routinely advised their patients on tooth cleaning methods; the use of manual orthodontic toothbrush (78.3%) and dental floss (51.7%) being popularly recommended methods. However, 51.7% used a specific demineralization preventive protocol at the start of treatment. Oral hygiene instruction was observed to be the most commonly adopted protocol (51.7%), followed by fluoride rinses (41.7%) (considered relatively ineffective). Extraoral hygiene instruction was the most common treatment protocol used when tooth demineralization occurred during and after treatment (56.7% and 73.3% respectively). Approximately 92% of the orthodontists agreed on the need for the development of a basic protocol to prevent demineralization. Conclusion: The demineralization preventive measures used by Nigerian orthodontists and orthodontic residents are inconsistent and not based on evidence-based information. The development of standardized demineralization prevention protocol was therefore recommended.

RESUMO

El Sistema Internacional de Clasificación y Manejo de la Caries (ICCMS) es un conjunto de protocolos clínicos basados en tener un mejor enfoque en el diagnóstico, tratamiento y prevención de la caries dental. Consiste en modificar los factores de riesgo y tratar los dientes con lesiones de caries activas para preservar la estructura del diente y restaurarlo solo cuando sea necesario. El objetivo de este estudio es presentar las herramientas de diagnóstico actuales para mejorar el proceso de toma de decisiones al seleccionar un plan de tratamiento y permitirnos una atención más individualizada en cada paciente.

The International System of Classification and Management of Caries (ICCMS) is a comprehensive set of clinical protocols aimed at providing a better approach to the diagnosis, treatment and prevention of dental caries. Modification of risk factors, treatment of teeth with active caries lesions and the preservation of the structure of dental enamel in order to restore tooth structure only when necessary are ideal approaches that odontopediatricians should incorporate into daily practice. The objective of this study was to present the current diagnostic tools to improve the decision-making process when selecting treatment plans and provide more individualized care to each patient.

RESUMO

Dental plaque is a biofilm composed of a complex oral microbial community. The accumulation of plaque in the pit and fissures of dental elements often leads to the development of tooth decay (dental caries). Here, potent anti-biofilm materials were developed by incorporating zinc methacrylates or di-n-butyl-dimethacrylate-tin into the light-curable sealant and their physical, mechanical, and biological properties were evaluated. The data revealed that 5% di-n-butyl-dimethacrylate-tin (SnM 5%) incorporated sealant showed strong anti-biofilm efficacy against various single-species (Streptococcus mutans or Streptococcus oralis or Candida albicans) and S. mutans-C. albicans cross-kingdom dual-species biofilms without either impairing the mechanical properties of the sealant or causing cytotoxicities against mouse fibroblasts. The findings indicate that the incorporation of SnM 5% in the experimental pit and fissure self-adhesive sealant may have the potential to be part of current chemotherapeutic strategies to prevent the formation of cariogenic oral biofilms that cause dental caries.
