Challenges to conducting research on oral health with older adults living in long-term care facilities.

BACKGROUND: The challenges to conducting oral health studies involving older people in long-term care facilities (LTCFs) must be debated. OBJECTIVE: This study aimed to investigate researchers' perceptions and experiences while conducting an epidemiological survey on oral health among older individuals residing in LTCFs. METHODS: A qualitative study was conducted involving six researchers who utilized field diaries to record their impressions during data collection through interviews (older individuals (or their proxies), caregivers, and LTCF coordinators) and oral examinations of the older people participants. Additionally, researchers responded to open-ended questions about their experiences. The collected material was subjected to content analysis by two researchers. RESULTS: The themes that emerged from the analysis were institutional context, aspects affecting the operationalization of the study, and data collection oriented by the clinical-functional profile of the older people. According to the researchers' perceptions, LTCF coordinators demonstrated concern for the study's benefits for older adults and the preservation of institutional routines during the research process. Caregivers emerged as vital sources of information, guiding researchers in navigating the challenges posed by the physical and mental complexities of the older people participants, necessitating empathy, sensitivity, and attentive listening from the researchers. The organization of materials and a streamlined data collection process proved essential for optimizing time efficiency and reducing stress for participants and researchers. CONCLUSION: The researchers recognized the important role played by LTCF coordinators and formal caregivers, underscoring the significance of empathetic methodologies and streamlined data collection processes in mitigating the challenges inherent to research conducted within LTCFs.

Ascorbic acid as a modulator of inflammatory response against Candida albicans.

Aim: To evaluate the behavior of oral keratinocytes in the presence of Vitamin C (Vit C) and its anti-inflammatory potential. Materials & methods: Oral keratinocytes were initially exposed to 0.1-2.5 mM of Vit C and the metabolic activity and cell migration were evaluated using MTS assay and Ibidi culture inserts, respectively. After, the cells were challenged with Candida albicans and inflammatory markers were analyzed by qPCR. Results: The treatment was not cytotoxic, and the highest concentrations increased the metabolic activity at 24 h. Vit C delayed the cell migration at 48 and 72 h. Interestingly, it downregulated the genes IL-8 and IL-1ß. Conclusion: Vit C could be an interesting adjuvant to anti-fungal treatment due to its anti-inflammatory potential.

Vitamin C, also known as ascorbic acid, is a vitamin commonly found in fruits and vegetables. It is popular for supporting our immune system, so is commonly taken as a supplement. We looked at the action of vitamin C on cells from the mouth and its potential to reduce inflammation in a fungal disease of the mouth ­ oral candidiasis. We showed that vitamin C is not toxic to cells of the mouth and may reduce inflammation in cells infected by the fungus. This suggests that vitamin C could be used as a complementary therapy for oral candidiasis.

Ultrasonography use for tongue cancer management: A scoping review.

BACKGROUND: Tongue cancer is associated with debilitating diseases and poor prognostic outcomes. The use of imaging techniques like ultrasonography to assist in the clinical management of affected patients is desirable, but its reliability remains debatable. Therefore, the aim of this study is to investigate the importance of ultrasound use for the clinicopathological management of tongue cancer. METHODS: A scoping review was carried out using specific search strategies in the following electronic databases: PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar. Collected data included bibliographical information, study design, ultrasound equipment, the aim of the ultrasonography use, the timing of ultrasound use during oncological treatment (pre-, trans-, and/or post-operatively), and the advantages and disadvantages of the use of the ultrasound. RESULTS: A total of 47 studies were included in this review after following the selection process. The majority of the studies investigated the use of ultrasound pre-operatively for the investigation of lymph node metastases or to determine the tumor thickness and depth of invasion. The sensitivity, specificity, and accuracy of ultrasound to determine clinical lymph node metastases ranged from 47% to 87.2%, from 84.3% to 95.8%, and from 70% to 86.2%, respectively. The sensitivity and specificity to determine the microscopic depth of invasion were 92.3% and from 70.6% to 82.1%, respectively. CONCLUSION: Ultrasonography seems to be a reliable imaging technique for the investigation of important prognostic parameters for tongue cancer, including depth of invasion and lymph node metastases.

Ecological niche modeling of two Microtheca Stål, 1860 species (Coleoptera: Chrysomelidae: Chrysomelinae) in the Americas: insights from Brassicaceae occurrence.

Biological invasions pose significant threats to biodiversity, with invasive species spread often facilitated by human activities. Consequently, this research utilized ecological niche modeling (ENM) to overcome this limitation and map the potential suitability of Microtheca ochroloma Stål, 1860 and Microtheca semilaevis Stål, 1860, which have been evaluated as potential insect pests in the Americas, zones for four genera of Brassicaceae, which include globally cultivated species such as Sinapis L., Raphanus L., Eruca Mill., and Brassica L. We utilized multiple methods to forecast the ecological habitat of Microtheca Stål, 1860 species based on distribution data and various environmental indicators. Our models, exhibiting high-performance metrics (TSS ranging from 0.84 to 0.96), revealed extensive environmental suitability for these species across the Americas, including previously unreported regions. The predicted zones overlapped significantly with areas where Brassicaceae crops were grown. Contrary to some previous assertions, our findings suggest that while these Microtheca species are recognized pests on these crops, their consistent widespread damage may be overstated. Nevertheless, their invasive potential could have broad ecological impacts, including biodiversity loss. Our research emphasizes the need for focused sampling in potential distribution zones and underlines the value of integrating ENM in predicting and managing invasive species spread.

Esketamine Augmentation in Treatment-Resistant Obsessive-Compulsive Disorder: A Retrospective Chart Review.

OBJECTIVE: Converging evidence supports the role of the glutamate, an excitatory amino acid neurotransmitter, in the pathophysiology of obsessive-compulsive disorder (OCD). Ketamine and esketamine, both noncompetitive N -methyl- d -aspartate antagonists, have emerged as a promising medication for this psychiatric disorder, given its possible efficacy with faster onset and good tolerability. The purpose of this retrospective chart review is to evaluate whether unbiased clinical documentation supports formal clinical trials of esketamine for an OCD indication. METHODS: A retrospective chart review of patients with treatment-resistant OCD receiving a single dose of esketamine (0.5mg/kg) added to standard therapy was conducted. The Yale-Brown Obsessive-Compulsive Scale and the Montgomery-Åsberg Depression Rating Scale were used to evaluate OCD and depressive symptoms respectively at baseline, 24 hours, and 7 days after esketamine administration. Descriptive statistics were used to analyze the data. RESULTS: Eight subjects were identified in this retrospective chart review: esketamine was administered subcutaneously in 7 and intravenously in 1. One week after infusion, 25% of the sample met criteria for treatment response and 50% for partial response. Major depressive disorder was a comorbid diagnosis in 75% of the sample and 2 of these subjects showed a positive antidepressant response. CONCLUSIONS: Our findings provide preliminary evidence that esketamine may reduce obsessive-compulsive symptoms in a subset of treatment-resistant OCD patients.

Validation of pairs of antagonist teeth for the evaluation of shortened dental arch in epidemiological studies.

The aim of this study was to evaluate the accuracy of pairs of antagonist teeth (epidemiological criterion) for defining pairs of teeth in occlusal contact (clinical criterion) and to estimate the agreement between the prevalence of "shortened dental arch" (SDA) and "functional dentition" (FD) when occlusal units (OUs) or posterior occluding pairs (POPs) are defined by the epidemiological or clinical criterion. Data were collected in an epidemiological oral health survey conducted in a municipality in Minas Gerais, Brazil. OUs and POPs were defined by the epidemiological criterion (dental crown status) or clinical criterion "gold standard" (carbon paper record of occlusal contacts during habitual maximum intercuspation). SDA corresponded to the presence of an intact anterior region and three to five OUs. FD was based on the concomitant presence of ≥ 1 tooth in each arch, 10 teeth in each arch, 12 anterior teeth, ≥ 3 premolar POPs, and ≥ 1 molar POP bilaterally. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the epidemiological criterion were calculated. The study included 197 adults. Sensitivity, specificity, PPV, and NPV were 88.5, 87.9, 92.5, and 81.9%, respectively, and accuracy was 88.3%. The epidemiological criterion proved to be valid and could be used in epidemiological studies to calculate the prevalence of reduced dental configurations that consider POPs. The assessment of oral functionality is an aspect that should be included in the diagnosis of the clinical condition of patients, contributing to a more effective individual and collective oral health care plan.

Psychopathological symptoms in parents and siblings of people on the autism spectrum: A systematic review and meta-analysis.

Parents and siblings of children on the autism spectrum experience significant distress, and for this reason, it is essential to understand the most prevalent psychopathological symptoms among this population. This work aims to establish the prevalence of psychopathological symptoms in parents and siblings of individuals on the autism spectrum, following the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) criteria. Searches were carried out using the PubMed/Medline, Embase, PsycINFO, SciELO, and Biblioteca Virtual em Saúde (BVS) databases. Twenty-three articles were included in this review. Depressive symptoms were the most frequently reported conditions, with a higher prevalence in mothers of children on the autism spectrum. In the meta-analysis, mothers of children on the autism spectrum scored higher by 0.42 standard deviations on the symptom scales (SMD 0.42; CI 0.25-0.59), with low statistical heterogeneity (I2 0%, p = 0.5) when compared with mothers of children with atypical development. The psychopathological symptoms of relatives should be investigated as part of the follow-up procedures for the child on the autism spectrum to facilitate their treatment.

Brain-derived neurotrophic factor serum levels following ketamine and esketamine intervention for treatment-resistant depression: secondary analysis from a randomized trial.

OBJECTIVES: Evidence suggests that ketamine's influence on brain-derived neurotrophic factor (BDNF) might be involved in its mechanism of rapid antidepressant action. We aimed to evaluate the differential impact of ketamine and esketamine on serum BDNF levels and its association with response patterns in treatment-resistant depression (TRD). METHODS: Participants (n = 53) are from a randomized, double-blind clinical trial comparing the efficacy of single-dose ketamine (0.5mg/kg, n = 27) and esketamine (0.25mg/kg, n = 26) in TRD. Depression severity was assessed before and 24 hours, 72 hours, and 7 days after the intervention, using the Montgomery-Åsberg Depression Rating Scale (MADRS). Blood samples were collected before infusion, 24 hours, and 7 days afterwards. RESULTS: There were no significant changes in BDNF levels at post-infusion evaluation points, and no difference in BDNF levels comparing ketamine and esketamine. Both drugs exhibited similar therapeutic effect. There was no association between BDNF levels and response to treatment or severity of depressive symptoms. CONCLUSION: There was no significant treatment impact on BDNF serum levels - neither with ketamine nor esketamine - despite therapeutic response. These results suggest that ketamine or esketamine intervention for TRD has no impact on BDNF levels measured at 24 hours and 7 days after the infusion.

A systematic review of measurement instruments for oral health assessment of older adults in long-term care facilities by nondental professionals.

BACKGROUND: Regular oral health assessment of older adults living in Long-term Care Facilities (LTCF) can improve their oral health. AIMS: This study aimed to systematically review studies describing the development of instruments employed by nondental professionals to assess the oral health of older adults in LTCF and to evaluate their measurement properties. MATERIAL & METHODS: Electronic searches were conducted in the MEDLINE (PubMed), Embase, Web of Science, Scopus, and LILACS databases. Measurement properties of the identified instruments were evaluated using the Consensus-based Standards to select health Measurement Instruments (COSMIN) checklist. Studies assessing at least one measurement property (validity, reliability, or responsiveness) of instruments used to assess oral health of older adults living in LTCF by nondental professionals were considered. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) checklist was used to evaluate the quality of evidence. RESULTS: Fifteen studies reporting measurement properties of seven instruments were selected. The ohr-interRAI and the OHAT were considered to have sufficient content validity, with high and moderate evidence quality, respectively. OHAT, BOHSE, and DHI showed acceptable results on reliability but with very low quality of evidence. DHI and OHSTNP also showed acceptable results for criterion validity, but, with low quality of evidence, insufficient or unclear results were observed for the remaining measurement properties. Studies evaluating the validity criteria of BOHSE and hypotheses testing of ohr-MDS were considered to have high evidence quality. DISCUSSION AND CONCLUSION: The ohr-interRAI can be provisionally recommended for use until further evidence is provided. Further methodologically rigorous studies are needed to assess the measurement properties of the existing instruments.

Aplicação do plasma de baixa temperatura sob pressão atmosférica como adjuvante ao tratamento da mucosite oral / Application of low temperature atmospheric pressure plasma as an adjuvant in treatment oral mucositis

A mucosite oral é um quadro clínico que acomete frequentemente pacientes sob terapia antineoplásica na região de cabeça e pescoço e caracteriza-se por ulcerações na mucosa que geram intensa dor local, odinofagia, aumento do risco de infecções, do uso de antibióticos e do tempo de hospitalização. A correlação entre mucosite oral, infecção fúngica e o potencial de disseminação fúngica sistêmica foi recentemente descrita. Apesar do impacto desse quadro clínico sobre a qualidade e tempo de vida dos pacientes oncológicos, não há consenso sobre a profilaxia e o protocolo terapêutico. O plasma de baixa temperatura sobre pressão atmosférica (LTAPP) apresenta efeito antimicrobiano, anti-inflamatório e reparador tecidual, o que sugere que possa ser promissor no tratamento da mucosite oral. Os objetivos gerais deste projeto foram divididos em dois subprojetos: 1) Definir os melhores parâmetros in vitro com efeito antifúngico e não tóxico e avaliar o LTAPP no tratamento de lesão de mucosite oral em modelo murino de mucosite por quimioterapia e 2) avaliar se o tratamento com LTAPP pode prevenir a disseminação fúngica sistêmica em ratos a partir de infecção experimental de lesões de mucosite oral por Candida albicans. Para tal, foram incluídos no estudo 100 ratos (Rattus norvegicus) com 90 a 100 dias de idade. No subprojeto 1, a lesão de mucosite oral foi induzida por administração de 5 fluorouracila (5-FU), enquanto no subprojeto 2, utilizou-se 5-FU associada à cisplatina ambas associadas à aplicação tópica de ácido acético 50%. Para o subprojeto 1, os animais foram randomicamente divididos em 2 grupos experimentais (n=30): a) Grupo mucosite; b) Grupo mucosite tratado com LTAPP, avaliados após 1, 5 e 12 dias do tratamento. Durante o período experimental, as lesões foram fotografadas e a gravidade da mucosite classificada por meio da atribuição de escores. Após a eutanásia e o processamento, os cortes histológicos corados por hematoxilina-eosina (HE) foram analisados microscopicamente. Para o subprojeto 2, o estudo de disseminação sistêmica fúngica nos grupos de mucosite infectada com C. albicans tratado ou não com LTAPP foi conduzido pelo isolamento fúngico a partir de amostras de sangue total e macerado dos órgãos. Para tanto foram estudados 2 grupos de ratos (n=20): c) Grupo mucosite infectado com C. albicans e d) Grupo mucosite infectado com C. albicans tratada com LTAPP, avaliados após 24 e 72 h do tratamento. Para ambos os projetos, o melhor parâmetro in vitro foi selecionado, isto é aquele com maior atividade antifúngica e baixa toxicidade. Dessa forma, as lesões foram expostas ao LTAPP de hélio por 5 min na distância de 1,5 cm na potência de 1 W. Os resultados in vitro mostraram que o LTAPP teve efeito antifúngico e baixa toxicidade para células de mamíferos. Os resultados in vivo mostraram que 5-FU afetou a saúde geral dos animais, evidenciada pela perda de peso corporal. Em ambos os grupos, houve reparo tecidual após 12 dias do tratamento, com resolução quase completa da lesão, o que foi corroborado pelos achados microscópicos. O grupo LTAPP exibiu uma tendência maior de redução da lesão, após 12 dias de tratamento. Além disso, o LTAPP apresentou efeito inibitório sobre C. albicans após 5 minutos, de exposição, com redução da recuperação fúngica da língua após 24 h (p<0.05). A disseminação fúngica sistêmica foi reduzida significativamente após 24 e 72 h do tratamento. Com base nos resultados obtidos, conclui-se que o LTAPP é uma ferramenta promissora para futura aplicação clínica em pacientes com mucosite oral. (AU)

Oral mucositis is a clinical condition that frequently affects patients undergoing antineoplastic therapy in the head and neck region and is characterized by mucosal ulcerations that generate intense local pain, odynophagia, increased risks of infections, use of antibiotics and the length of hospital stay. The correlation among oral mucositis, fungal infection and the potential for systemic fungal dissemination has recently been described. Despite the impact of this clinical condition on the quality and life expectancy of cancer patients, there is no consensus on prophylaxis and the therapeutic protocols. Low temperature atmospheric pressure plasma (LTAPP) has antimicrobial, anti-inflammatory and tissue repairing effects, which suggests that it can be promising in the treatment of oral mucositis. The general objectives of this project were divided into two subprojects: 1) Define the best antifungal and non-toxic in vitro parameters and to evaluate the application of LTAPP in the treatment of oral mucositis in murine model for chemotherapy, and 2) to evaluate whether treatment with LTAPP can prevent systemic fungal dissemination in rats from experimental infection of oral mucositis lesions by Candida albicans. A total of 100 rats (Rattus norvegicus) aged 90 to 100 days were included in the study. In subproject 1, oral mucositis lesion was induced by administration of only 5- fluorouracil (5-FU), while in subproject 2, administration and systemic administration of 5-FU associated with cisplatin, both associated with topical application of 50% acetic acid. For subproject 1, the animals were randomly divided into 2 experimental groups (n=30):a) Mucositis group and b) Mucositis group treated with LTAPP evaluated after 1, 5 and 12 days of treatment. During the experimental period, the lesions were photographed, and the severity of mucositis was classified into scores. After euthanasia and processing, the histological cuts stained by hematoxylin-eosin (HE) were analyzed. For subproject 2, the study of fungal systemic dissemination in groups of mucositis infected with C. albicans treated or not with LTAPP was conducted by fungal isolation from whole blood and macerated organs. Therefore, 2 groups of rats (n=20) were studied: c) Mucositis group infected with C. albicans and d) Mucositis group infected with C. albicans treated with LTAPP, evaluated after 24 and 72 h of treatment. For both subprojects, the best in vitro parameter was selected, that is, the one with the greatest antifungal effect and low toxicity. Thus, the lesions were exposed to helium LTAPP for 5 min at a distance of 1.5 cm at power of 1 W. In vitro results showed that LTAPP has an antifungal effect and low toxicity. In vivo results showed that 5-FU affected the general health of animals evidenced by body weight loss. In both groups, there was tissue repair after 12 days of treatment, with almost complete resolution of the lesion, which was corroborated by the microscopic findings. LTAPP group showed a greater trend of reduction of lesion, after 12 days of the treatment. Furthermore, LTAPP showed inhibitory effect on C. albicans after 5 min of exposition, with reduction in fungal recovery from the tongue after 24 h (p<0.05). Reduction in fungal dissemination was observed after 24 and 72 h of LTAPP treatment (p<0.05). Based on the obtained results, it was concluded that LTAPP is a promising tool for future clinical application in patients with oral mucositis.(AU)

Hipersensibilidade dentinária e satisfação com a saúde mediada pela presença de impacto físico e psicossocial das condições bucais: uma análise de caminhos / Dentin hypersensitivity and health satisfaction mediated by the presence of physical and psychosocial impacts of oral conditions: a pathway analysis

Objetivo: Objetivou-se investigar associação direta e mediada pela presença de impacto físico e psicossocial das condições bucais entre HD e satisfação com a saúde entre adultos. Métodos: Estudo transversal foi realizado entre 2018-2019 com amostra probabilística por conglomerado de adultos residentes em Rio Acima (MG). Entrevista e exame bucal foram realizados por examinadoras calibradas. Satisfação com a saúde foi avaliada por meio da pergunta doWHOQoL-bref "Quão satisfeito (a) você está com a sua saúde?" e suas respostas categorizadas entre "satisfeito" e "insatisfeito". HD foi avaliada por estímulo tátil na região cervical dos dentes. Presença de impactos físicos e psicossociais das condições bucais foi definida pelas respostas "repetidamente" ou "sempre" a pelo menos um dos itens do OHIP-14. Covariáveis foram dados sociodemográficos e econômicos, comportamentos em saúde, condições de saúde bucal e uso de serviços odontológicos. Associações foram investigadas por modelos de Regressão de Poisson e Modelagem de Equações Estruturais (MEE) para estimar associações diretas e indiretas (Stata 16). Resultados: Dos 197 adultos, 132 (66,18%) declararam estar satisfeitos com sua saúde e 73 indivíduos (38,75%) apresentavam HD. Houve associação significativa entre presença de HD e presença de impacto físico e psicossocial das condições bucais (RP: 1.34; IC 95%: 1.08­1.67), enquanto para satisfação a associação com HD não foi significativa (RP: 1.08; IC 95%: 0.75-1.54) após a inclusão da variável presença de impacto físico e psicossocial das condições bucais. MEE demonstrou associação direta não significativa entre HD e satisfação, enquanto a associação indireta mediada pela presença de impacto físico e psicossocial das condições bucais foi significativa. Conclusão: Indivíduos com HD podem relatar maior insatisfação com a vida quando esta experiência dolorosa está associada com impactos físicos ou psicossociais.

Aim: Dentin Hypersensitivity (DH) is a painful condition that affects the Oral Health-related Quality of Life and can affect the satisfaction with health of individuals who have it. This study aimed to investigate the direct association mediated by the presence of physical and psychosocial impacts of oral conditions between DH and satisfaction with health among adults. Methods: A cross-sectional study was carried out between 2018-2019 with a probabilistic sample consisting of a cluster of adults living in Rio Acima (MG). Interviews and epidemiological examinations were performed using calibrated tests. The dependent variable of satisfaction with health was assessed using the WHOQoL-bref question "How satisfied are you with your health?" Participants' answers were categorized between "satisfied" and "dissatisfied". The independent DH variable was assessed by tactile stimulation in the cervical region of the teeth. The presence of physical and psychosocial impacts of oral conditions was defined by the answers "farly often" or "very often" to at least one of the OHIP-14 items. Covariates were sociodemographic and psychological data, health behavior, oral health conditions, and use of dental services. Associations were investigated by Poisson Regression and Structural Equation Modeling (SEM) models to estimate direct and indirect associations (Stata 16). Results: Of the 197 adults, 132 (66.18%) reported being satisfied with their health, and 73 individuals (38.75%) had DH. There was a significant association between the presence of DH and the presence of physical and psychosocial impacts of oral health (PR:1.34; 95% CI: 1.08­1.67), while for receiving the association with DH, it was not significant (PR:1 .08; 95% CI: 0.75-1.54) after including the presence of impact variables. SEM showed a non-significant direct association between DH and satisfaction, while the indirect association mediated by the presence of impact was significant. Conclusion: Individuals with HD may report greater dissatisfaction with life when this painful experience is associated with physical or psychosocial effects.

Effect of the pH on the Antibacterial Potential and Cytotoxicity of Different Plasma-Activated Liquids.

In this study, different plasma-activated liquids were evaluated for their antimicrobial effects against Escherichia coli, as well as for their cytotoxicity on mammalian cells. The PALs were prepared from distilled (DIS), deionized (DI), filtered (FIL), and tap (TAP) water. Additionally, 0.9% NaCl saline solution (SAL) was plasma-activated. These PALs were prepared using 5 L/min air gliding arc plasma jet for up to 60.0 min of exposure. Subsequently, the physicochemical properties, such as, the oxidation-reduction potential (ORP), the pH, the conductivity, and the total dissolved solids (TDS) were characterized by a water multiparameter. The PALs obtained showed a drastic decrease in the pH with increasing plasma exposure time, in contrast, the conductivity and TDS increased. In a general trend, the UV-vis analyses identified a higher production of the following reactive species of nitrogen and oxygen (RONS), HNO2, H2O2, NO3-, and NO2-. Except for the plasma-activated filtered water (PAW-FIL), where there was a change in the position of NO2- and NO3- at some pHs, The higher production of HNO2 and H2O2-reactive species was observed at a low pH. Finally, the standardized suspensions of Escherichia coli were exposed to PAL for up to 60.0 min. The plasma-activated deionized water (PAW-DI pH 2.5), plasma-activated distilled water (PAW-DIS pH 2.5 and 3), and plasma-activated tap water (PAW-TAP 3.5) showed the best antimicrobial effects at exposure times of 3.0, 10.0, and 30.0 min, respectively. The MTT analysis demonstrated low toxicity of all of the PAL samples. Our results indicate that the plasma activation of different liquids using the gliding arc system can generate specific physicochemical conditions that produce excellent antibacterial effects for E. coli with a safe application, thus bringing future contributions to creating new antimicrobial protocols.

Silver-Coated Silica Nanoparticles Modified with MPS: Potential Antimicrobial Biomaterials Applied in Glaze and Soft Reliner.

Soft reliner and glaze are materials used over full or partial dental prosthesis to prevent excessive pressure on the supporting tissues. They are also indicated as supportive treatment for dental stomatitis, especially when modified by the addition of medications. The objective of the work was to evaluate the antimicrobial effect of silver-coated silica nanoparticles in a glaze and a soft reliner. The nanoparticles were synthesized, characterized, and tested by minimum inhibitory concentration (MIC) for C. albicans SC5314. Then, the nanoparticles were incorporated to a glaze and a soft reliner, which were called nanocomposites. Then, the nanocomposites were divided into six groups (n = 12): CG: glaze/reliner; CR: reliner; G1: glaze + 1% nanoparticles/reliner; G2: glaze + 2.5% nanoparticles/reliner; R1: reliner + 1%; R2: reliner + 2.5%. The nanocomposites were characterized by a goniometer and by a scanning electron microscope. The antibiofilm test was performed against C. albicans SC5314. According to the MIC results, the non-functionalized nanoparticles reduced fungal growth at 1000 µg/mL and the functionalized nanoparticles at 2000 µg/mL. The functionalized nanoparticle had a superior dispersion being selected for the antibiofilm test. There was a reduction of 64% in CFU/specimen count for the glaze, not statistically significant (p = 0.244). For the soft reliner, there was an increase in CFU/specimen with the presence of nanoparticles, still not statistically significant (p = 0.264). In conclusion, it is necessary to conduct new studies to increase the release of silver, thus improving nanoparticles' antifungal potential.

Facial Scanning and Additive Manufacturing Used in Production Nasal Prosthesis.

Maxillofacial prosthesis is an effective treatment for patients with facial sequelae, but it remains challenging for professionals due to its high esthetic complexity. This study describes a clinical case of successful nasal prosthetic rehabilitation using digital technology and additive manufacturing. Initially, the 76-year-old patient, with a facial defect in the nasal region, had her face scanned with 3-dimensional scanner for laboratory planning of the prototype of a nasal prosthesis. After approving the prototype image, working models in muffle shape were obtained in additive manufacture for the inclusion of the prosthesis. In the final session, the prosthesis was colored extrinsically and installed. The procedures digital in the manufacture of the facial prosthesis was applicable and agile, allowing the professional greater predictability regarding the shape of the rehabilitated organ, esthetic improvement in the mutilated area and patient satisfaction in relation to the speed, of the procedure and the quality of the prosthesis.
