Cartilha ilustrada tátil sobre saúde bucal para pessoas com deficiência visual / Tactile illustrated booklet on oral health for visually impaired people

A deficiência visual é considerada uma deficiência sensorial que pode dificultar o aprendizado para manter a saúde bucal, dentre outras questões, devido à falta de cuidados preventivos e orientações utilizando materiais adequados. Este trabalho tem como objetivo demonstrar a elaboração de Cartilha Ilustrada Tátil (CIT) com a orientações sobre saúde bucal para Pessoas com Deficiência Visual (PDV). Para elaboração de tal material foram utilizados: macromodelos preexistentes, materiais de uso odontológico associados a outros encontrados em papelarias. A partir destes materiais foi possível confeccionar um protótipo de CIT, sendo este um material inédito para educação em saúde bucal para a PDV.

Visual impairment is considered a sensory disability that can hinder learning to maintain oral health, among other issues, due to lack of preventive care and guidance using appropriate materials. This work aims to demonstrate the elaboration of an Illustrated Tactile Booklet (ITB) with guidelines on oral health for People with Visual Impairment (PVI). For the preparation of such material, preexisting macromodels, materials for dental use associated with others found in stationery stores were used. From these materials it was possible to make a prototype of ITB, which is an unprecedented material for oral health education for the PVI.

Odontologia e osteoporose: uma revisão narrativa / Dentistry and osteoporosis: a narrative review

A osteoporose é caracterizada pela perda óssea e pelo comprometimento da resistência do osso. Essa patologia afeta, também, os ossos da face e consequentemente interfere na atuação dos profissionais da odontologia. Assim sendo, o presente trabalho revisou a literatura acerca da relação entre osteoporose e odontologia. O levantamento dos dados se deu por consulta a livros e nas bases de dados Biblioteca Virtual em Saúde (BVS), PubMed e Scientific Eletronic Library Online (SciELO) e como Descritores em Ciência da Saúde (Decs) foram adotados os termos: "Odontologia", "Osteoporose" e "Saúde bucal". A osteoporose diminui a massa e aumenta a porosidade óssea na maxila e na mandíbula, podendo provocar até quatro vezes mais perda dentária. Os bifosfonatos, principal classe medicamentosa utilizada para o tratamento de osteoporose, estão associados à ocorrência de osteonecrose dos maxilares e ao aumento de tempo de tratamento ortodôntico. Assim, pode-se concluir que é imprescindível o conhecimento do cirurgião-dentista acerca da osteoporose para uma segura abordagem e execução de tratamento.

Osteoporosis is characterized by bone loss and compromised bone strength. This pathology also affects the bones of the face and consequently interferes with the work of dentists. Therefore, the present study reviewed the literature about the relationship between osteoporosis and dentistry. Data collection was carried out by consulting books and the databases Biblioteca Virtual em Saúde (BVS), PubMed and Scientific Electronic Library Online (SciELO) and as Medical Subjects Headings (MeSH) the terms adopted were: "Dentistry", "Osteoporosis" and "Oral health". Osteoporosis reduces bone mass and increases bone porosity in the maxilla and jaw, which can cause up to four times more tooth loss. Bisphosphonates, the main class of medications used to treat osteoporosis, are associated with the occurrence of osteonecrosis of the jaw (ONJ) and increase the time of orthodontic treatment. Thus, it can be concluded that the dentist's knowledge of osteoporosis is necessary for a safe approach and execution of treatment.

Complicações da comunicação buco-sinusal em cirurgias bucais: fatores de riscos, complicações e intervenções / Complications of oral-sinusal communication in oral surgery: risk factors and interventions

A comunicação buco-sinusal, uma conexão direta entre boca e seios maxilares, ocorre comumente pela extração de dentes próximos ao seio maxilar e outros procedimentos. O diagnóstico precoce é crucial para prevenir complicações graves. A abordagem terapêutica varia conforme o tamanho do defeito, presença de infecção e localização específica. Realizou-se uma breve revisão de literatura qualitativa abordando as principais complicações da comunicação buco sinusal na cirurgia bucal e como intervi-las. Buscou-se artigos científicos indexados nas seguintes bases de dados: Google Scholar, Pubmed e Biblioteca Scielo com lapso temporal de 2013 a 2023. Foram utilizados para esta busca os seguintes descritores: Comunicação buco-sinusal; Complicações; Seio maxilar. Os critérios de inclusão desta pesquisa foram artigos em inglês, português e espanhol, sendo selecionados 26 trabalhos. Os principais critérios de exclusão foram artigos com mais de 10 anos de publicação. A prevenção e gestão eficaz das complicações na comunicação oral em cirurgias são essenciais. Identificar fatores de risco, usar técnicas cirúrgicas precisas e agir imediatamente diante de sinais de comunicação com os seios da face são medidas cruciais para garantir a segurança do paciente e aprimorar os resultados cirúrgicos.

Oral-sinusal communication, a direct connection between the mouth and maxillary sinuses, commonly occurs due to the extraction of teeth close to the maxillary sinus and other procedures. Early diagnosis is crucial to prevent serious complications. The therapeutic approach varies according to the size of the defect, presence of infection and specific location. A brief qualitative literature review was carried out looking at the main complications of oral sinus communication in oral surgery and how to intervene. We searched for scientific articles indexed in the following databases: Google Scholar, Pubmed and Scielo Library with a time span from 2013 to 2023. The following descriptors were used for this search: Oral-sinus communication; Complications; Maxillary sinus. The inclusion criteria for this study were articles in English, Portuguese and Spanish, and 26 papers were selected. The main exclusion criteria were articles published more than 10 years ago. The prevention and effective management of oral communication complications during surgery are essential. Identifying risk factors, using precise surgical techniques and acting immediately in the event of signs of communication with the sinuses are crucial measures to ensure patient safety and improve surgical outcomes.

Etiopatogenia e tratamento da osteonecrose dos maxilares induzida por medicamentos: aspectos essenciais ao dentista / Etiopathogenesis and treatment of medication-related osteonecrosis of the jaw: essential aspects for the dentist

A osteonecrose dos maxilares induzida por medicamentos (MRONJ) caracteriza-se por exposição óssea ou osso que pode ser sondado através de fístula intra ou extraoral, em região maxilofacial, e que não cicatriza dentro de oito semanas. A MRONJ é uma condição rara e debilitante que pode causar dor, disfagia e odor desagradável na cavidade oral, afetando pacientes com histórico ou sob uso contínuo de terapia antirreabsortiva, isolada ou associada a imunomoduladores ou drogas antiangiogênicas, mas sem histórico de radioterapia nos maxilares. O objetivo desta revisão narrativa de literatura é compilar os principais aspectos sobre a etiopatogenia da MRONJ e as opções terapêuticas disponíveis. A etiologia da MRONJ é multifatorial, complexa, e não está totalmente compreendida, não havendo um tratamento definitivo, mas diversas modalidades terapêuticas que visam o controle da dor e da progressão da osteonecrose. Conclui-se com essa revisão que o entendimento da etiopatogenia da MRONJ pelo cirurgião-dentista lhe permite adotar medidas preventivas, bem como o conhecimento das modalidades terapêuticas disponíveis lhe possibilita oferecer o manejo adequado para seu paciente, conforme o estágio da doença.

Medication-related osteonecrosis of the jaw (MRONJ) is characterized by exposed bone or bone that can be probed through an intra or extraoral fistula, in the maxillofacial region, which does not heal within eight weeks. MRONJ is a rare and debilitating condition that can cause pain, dysphagia and unpleasant odor in the oral cavity, affecting patients with a history or continuous use of antiresorptive therapy, alone or associated with immunomodulators or antiangiogenic drugs, but without a history of radiotherapy to the jaws. The aim of this narrative literature review is to compile the main aspects about the etiopathogenesis of MRONJ and the available therapeutic options. The etiology of MRONJ is multifactorial, complex, and is not fully understood, with no definitive treatment, but several therapeutic modalities that aim to control pain and the progression of osteonecrosis. It is concluded from this review that the understanding of the etiopathogenesis of MRONJ by the dental surgeon allows him to adopt preventive measures, as well as the knowledge of the therapeutic modalities available allows him to offer the appropriate management for his patient, depending on the stage of the disease.

Práticas integrativas e complementares de saúde em Sergipe / Integrative and complementary health practices in Sergipe

A atenção primária em saúde (APS) é o primeiro nível de atenção em saúde, sendo um elo entre a população e o setor de saúde. Tem-se buscado a humanização dos atendimentos, e essa mudança, refletida pelas mudanças da sociedade, trouxe a implementação da Política Nacional de Práticas Integrativas e Complementares (PNPIC) no SUS. O objetivo deste trabalho foi realizar uma análise da tendência da quantidade das práticas integrativas e complementares realizadas nas regionais de saúde de Sergipe de 2017 a 2023, associando com a cobertura da atenção primária. Foi realizada análise de dados secundários através do Departamento de Informática do Sistema Único de Saúde (DATASUS), como forma de organização no período de junho/2015 a junho/2023 por regional de saúde de Sergipe. As análises dos dados foram descritivas e de correlação e por meio de análise de série temporal. A regional de saúde de Lagarto foi a que mais executou as práticas integrativas e complementares no período analisado e algumas regionais não tiveram continuidade na realização destas práticas. A regional de saúde com maior cobertura de APS foi Itabaiana. Não foi possível observar associação entre o número de práticas e a cobertura de atenção primária. Com o intuito de que o atendimento aos indivíduos seja cada vez mais humanizado, e em virtude da realização das práticas integrativas ter baixo índice ou descontinuidade em algumas regiões de Saúde de Sergipe, é relevante que os profissionais de saúde busquem conhecimentos sobre essas práticas, como também, os gestores em saúde incentivem esta ação.

Primary health care (PHC) is the first level of health care, being a link between the population and the health sector. The aim has been to humanize care, and this change, reflected by changes in society, has led to the implementation of the National Policy on Integrative and Complementary Practices (PNPIC) in the SUS. The objective of this work was to carry out an analysis of the trend in the number of integrative and complementary practices carried out in the health regions of Sergipe from 2017 to 2023, associating it with primary care coverage. Secondary data analysis was carried out through the Department of Informatics of the Unified Health System (DATASUS), as a form of organization from June/2015 to June/2023 by health region in Sergipe. Data analyzes were descriptive and correlational and through time series analysis. The Lagarto health region was the one that carried out the most integrative and complementary practices in the period analyzed and some regions did not continue to carry out these practices. The health region with the highest PHC coverage was Itabaiana. Observing an association between the number of practices and primary care coverage was impossible. With the aim that care for individuals is increasingly humanized, and because the implementation of integrative practices has a low rate or discontinuity in some Health regions of Sergipe, health professionals must seek knowledge about these practices as well as health managers encourage this action.

Impact of 5-Lipoxygenase Deficiency on Dopamine-Mediated Behavioral Responses.

The 5-lipoxygenase/leukotriene system has been implicated in both physiological and pathological states within the central nervous system. Understanding how this system interacts with the dopaminergic system could provide valuable insights into dopamine-related pathologies. This study focused on examining both motor and non-motor dopamine-related responses in 5-lipoxygenase/leukotriene-deficient mice. We used pharmacological agents such as amphetamine, apomorphine, and reserpine to challenge the dopaminergic system, evaluating their effects on prepulse inhibition reaction (PPI), general motor activity, and oral involuntary movements. Additionally, we analyzed striatal glial marker expression (GFAP and Iba-1) in reserpine-treated mice. The 5-lipoxygenase/leukotriene-deficient mice exhibited increased spontaneous locomotor activity, including both horizontal and vertical exploration, along with stereotyped behavior compared to wild-type mice. This hyperactivity was reduced by acute apomorphine treatment. Although basal PPI responses were unchanged, 5-lipoxygenase/leukotriene-deficient mice displayed a significant reduction in susceptibility to amphetamine-induced PPI disruption. Conversely, these mice were more vulnerable to reserpine-induced involuntary movements. There were no significant differences in the basal expression of striatal GFAP and Iba-1 positive cells between 5-lipoxygenase/leukotriene-deficient and wild-type mice. However, reserpine treatment significantly increased GFAP immunoreactivity in wild-type mice, an effect not observed in 5-lipoxygenase-deficient mice. Additionally, the percentage of activated microglia was significantly higher in reserpine-treated wild-type mice, an effect absents in 5-lipoxygenase/leukotriene-deficient mice. Our findings suggest that 5-lipoxygenase/leukotriene deficiency leads to a distinctive dopaminergic phenotype, indicating that leukotrienes may influence the modulation of dopamine-mediated responses.

Tongue Metastasis of Mucinous Colorectal Adenocarcinoma: Report of a Rare Case.

Metastases in the oral and maxillofacial region, particularly in soft tissues, are exceedingly rare. Such metastases can present as swelling in older individuals, especially in the tongue and gingiva. Furthermore, colorectal metastases at this site are commonly found in the mandible and gingiva and usually share the same morphology as the primary tumor. Herein, we report the case of a 61-year-old woman with a metastatic nodule in the tongue covered by normal mucosa. The clinical, histopathological, and immunohistochemical findings were essential for the final diagnosis of colorectal metastasis, consistent with adenocarcinoma with mucinous differentiation and intestinal phenotype. Metastases of colorectal adenocarcinoma to the tongue are rare but should be included in the differential diagnosis of nodular lesions at this site. The diagnosis can therefore be made based on meticulous clinical and histopathological examination complemented by immunohistochemistry.

Oral diseases and systemic conditions: correlation analyses from the Colombian national health records between 2016 and 2023.

Introduction: Prevalence of oral, metabolic, circulatory, and nutritional diseases has tended to increase globally. As these diseases have common contributing factors, such as unhealthy diets, evaluating their epidemiological trends and the relation between them is relevant. In Colombia, the Ministry of Health records the frequency of consultation for these diseases through the Integrated Social Protection Information System. It facilitates the evaluation of their epidemiological behavior at the population level. Aim: To analyze and correlate the burden of oral diseases (caries and periodontitis) with respect to nutritional, circulatory and metabolic pathologies, as well as their relationships with socioeconomic indices in Colombian regions from 2016 to 2023. Methods: This study analyzes retrospective data collected between 2016 and 2023 by the National Health Registry in Colombia (SISPRO) according to the ICD-10. Sociodemographic data and the number of disease consultations were extracted. The number of consultations for oral diseases was correlated with systemic pathologies, socioeconomic indices through the Spearman test. Associations were explored via multiple linear regressions. A Principal Component Analyses (PCA) was conducted to identify patterns between socioeconomic, oral and systemic disease variables, as well as to reduce the complexity of the analysis by creating clusters that capture the greatest possible variability in the data. Results: The average number of consultations per biennium was 24.550.435 being the highest number for 2018-2019. The highest percentage of consultations was related to extensive caries, followed by chronic gingivitis. Moreover, consultations for oral diseases were found to correlate with systemic pathologies. All socioeconomic indices were associated with caries and/or periodontal diseases. This study is the first in Colombia that uses national data on diagnoses assigned to medical and dental consultations. PCA revealed a clustering pattern of pathologies suggesting that they are highly associated one to each other. Conclusion: Correlations between consultations for oral and systemic diseases stratified by life cycle and socioeconomic indices highlight the importance of conducting epidemiological and public health characterizations and their associations. Identifying these factors is imperative in the prevention and management of both diseases.

The impact of caregiver training on the oral health of people with disabilities: A systematic review.

AIMS: This systematic review aimed to assess the impact of oral health training for caregivers of individuals with disabilities. MATERIALS AND METHODS: A systematic review was conducted using five electronic databases: Medline (PubMed), SciELO, Web of Science, LILACS, and CAFe, adhering to PRISMA guidelines. The PICO strategy was defined as follows: Participants: caregivers of individuals with disabilities; Intervention: training or education in oral health for caregivers; Control: no caregiver training; and Outcomes: evaluating whether oral health training for caregivers improves the oral health of people with disabilities. The study aimed to address the research question: "What is the impact of oral health training for caregivers of individuals with disabilities?" The study was preregistered in PROSPERO (CRD42023416760). RESULTS: A total of 14 studies were included, with trained caregivers being either staff members or parents, and various disabilities reported, with cerebral palsy being the most prevalent. Caregiver training methods varied, such as instructions on the importance of oral health care, supervised oral hygiene, and demonstration of toothbrushing techniques. Overall, the intervention groups showed an improvement in measures such as to the Gingival Index, Plaque Index, Simplified Oral Hygiene Index, and Gingival Bleeding Index on upon probing. Additionally, improvements were observed in the quality, frequency, and duration of toothbrushing among intervention groups. CONCLUSION: The findings suggest that oral health training for caregivers has a positive impact on the oral health of individuals with disabilities, potentially leading to better oral health outcomes.

Energy Metabolic Profile in Oral Potentially Malignant Disorders and Oral Squamous Cell Carcinoma: A Preliminary Landscape of Warburg Effect in Oral Cancer.

We hypothesized that cell energy metabolic profiles correlate with normal, dysplastic, and tumor cell/tissue statuses and may be indicators of aggressiveness in oral squamous cell carcinoma (OSCC) cells. The energy-related proteins that were differentially expressed in human OSCC fragments (n = 3) and their adjacent epithelial tissue (TAE) were verified using mass spectrometry (MS). Immunohistochemistry for 4-hydroxynonenal (4-HNE) was performed to evaluate the oxidative stress patterns in OSCC (n = 10), epithelial dysplasia (n = 9), and normal epithelial (n = 4) biopsies. The metabolic energy profile of OSCC aggressiveness was investigated in human OSCC cell lines with different levels of epithelial-mesenchymal transition proteins. The genes associated with the proteins found by MS in this study were analyzed using survival analysis (OS), whereas the genes associated with a poorer prognosis were analyzed using context-specific expression, Gene Ontology (GO) and Cancer Hallmarks for function enrichment analysis. The rationale for all experimental approach was to investigate whether the variation in energy metabolism profile accompanies the different phenotypes (from epithelial to mesenchymal) during the epithelial-mesenchymal transition. All OSCC fragments exhibited an increase in glycolysis-related proteins and a decrease in mitochondrial activity compared to the TAE region (p < 0.05), probably due to the downregulation of pyruvate dehydrogenase and antioxidant proteins. Additionally, the OSCC cell lines with a mesenchymal profile (SCC4, SCC9, and SCC25) had a lower mitochondrial mass and membrane potential and generated lower levels of reactive oxygen and nitrogen species than the TAE region. When we analyzed 4-HNE, the reactive species levels were increased in the epithelial regions of OSCC and potentially malignant lesions. A decrease in the levels of 4-HNE/reactive species was observed in the connective tissue underlying the dysplastic regions and the OSCC invasion zone. Based on this scenario, aggressive OSCC is associated with high glycolytic and oxidative metabolism and low mitochondrial and antioxidant activities, which vary according to the differentiation level of the tumor cells and the stage of carcinogenesis.

Myofibroma with Atypical Features can Mimic Low-Grade Myofibroblastic Sarcoma: Two Paediatric Cases.

Myofibroma is a rare benign mesenchymal tumor that frequently affects the pediatric population with a predilection for the head and neck region. About 10% of myofibroma cases, presenting atypical features, can be misinterpreted as low-grade myofibroblastic sarcoma (LGMS), with therapeutic and prognostic impact. Here, we report two pediatric cases of benign myofibroblastic tumors, one of them showing typical characteristics of myofibroma, the other was an atypical myofibroma, which initially mimicked low-grade myofibroblastic sarcoma. Atypical myofibromas, despite its distinctive characteristics, follow a benign course, similar with typical myofibroma. It is necessary to distinguish atypical myofibroma from low-grade myofibroblastic sarcoma and avoid unnecessary invasive therapy.

Mantle Cell Lymphoma in the Oral Cavity: Exploring the Differential Microscopic Diagnosis of a Rare Case.

Mantle cell lymphoma (MCL) is a rare subtype of B-cell non-Hodgkin's lymphoma (NHL), which generally has an aggressive course. Its pathophysiology seems to be related with the malignant transformation of B-cell mantle zone lymphocytes due to the CCND1 rearrangement. The occurrence of MCL in the oral cavity is especially rare. In this report, we present an exceptional case of oral MCL diagnosed in the palate in a 56-year-old male patient, highlighting its distinct morphological and immunohistochemical features that may assist in the accurate diagnosis.

Oral glucose tolerance test curve shape in Mexican children and adolescents with and without obesity.

OBJECTIVES: Mexican children with obesity are at a higher risk of developing type 2 diabetes mellitus (T2DM). The aim of the study was to compare oral glucose tolerance test (OGTT) characteristics: time of peak glucose, glucose level ≥155 mg/dL at 1 h, presence of metabolic syndrome (MetS), sensitivity, secretion, and oral disposition index (oDI) in children with and without obesity, according to oral glucose tolerance curve shape: monophasic or biphasic. METHODS: Cross-sectional study including 143 children. Groups were divided into (a) obese: biphasic (B-Ob) (n=55) and monophasic (M-Ob) (n=50), (b) without obesity: biphasic (B-NonOb) (n=20) and monophasic (M-NonOb) (n=18). RESULTS: Late glucose peak was more frequent in the M-Ob group (p<0.001). Glucose levels ≥155 mg/dL and MetS were more frequent in the M-Ob group but did not show significance. The groups with obesity (biphasic and monophasic) had higher indices of insulin resistance and insulin secretion compared to the nonobese groups (biphasic and monophasic) (p<0.001). AUC glucose was higher in the M-Ob group (p<0.05), and AUC insulin was higher in the M-NonOb group. oDI (Matsuda) was significantly lower in the M-Ob group compared to the other groups (p<0.001), and oDI-HOMA IR was higher in M-NonOb group (p=0.03). CONCLUSIONS: All OGTT parameters could help to identify Mexican children at increased risk of developing T2DM, not only fasting plasma glucose and 2 h glucose. M-Ob in non-T2DM Mexican children reflects an early defect in glucose metabolism. Higher level of IR indexes in M-NonOb vs. B-NonOb could indicate an increased risk for T2DM of genetic origin.

Botulinum toxin for the management of bruxism: an overview of reviews protocol.

INTRODUCTION: Bruxism is characterised by a repetitive activity in the masticatory muscles that involves teeth clenching or grinding and/or forceful mandibular movements. Its management is typically initiated when individuals start experiencing the adverse effects of the condition. One of the available intervention forms is the administration of botulinum toxin type A (BoNT-A). Numerous systematic reviews have addressed the use of BoNT-A to manage bruxism; however, the results are controversial. The current overview aims to determine BoNT-A's effectiveness for managing bruxism in relation to placebo, the absence of treatment or alternative interventions in the adult population. METHODS AND ANALYSIS: This study will include systematic reviews (SRs), with or without meta-analysis, aiming to evaluate the efficacy of BoNT-A for bruxism in adults. A broad literature search will be carried out on Cochrane Library, EMBASE, LILACS, Livivo, PubMed/MEDLINE, Scopus, Web of Science and the grey literature. Experts in the topic and reference lists of included SRs will also be consulted. The study selection will be conducted in two phases by two independent reviewers. Data collection will be performed by one author and cross-checked by another. The methodological quality of included SRs will be evaluated using AMSTAR-II. A narrative synthesis will be employed as the formal method to combine individual study data. The overlap across studies will be quantified by the corrected covered area and illustrated by the Graphical Representation of Overlap for Overviews. ETHICS AND DISSEMINATION: This overview does not require ethics approval, as it uses secondary data from previously published studies. The results will be disseminated through the publication in a high-impact journal. OSF OF REGISTRATION: DOI: 10.17605/OSF.IO/RB45T.

Oral calcium supplementation versus placebo in mitigating citrate reactions during apheresis: an open-label randomized control trial.

BACKGROUND: Citrate-related hypocalcemia is the most common adverse event linked with peripheral blood progenitor cell apheresis. A previous retrospective study highlighted the prophylactic effectiveness of oral calcium drinks before apheresis, supplemented with intravenous calcium gluconate. Consequently, this study is a randomized controlled trial comparing oral calcium with placebo drinks STUDY DESIGN AND METHODS: Healthy donors were randomized to receive either oral calcium (Cohort A) or placebo (Cohort B) drinks. If symptoms emerged, all donors were given calcium drinks to counteract hypocalcemia. The primary endpoint centered on the incidence of Grade 1 or higher citrate-related symptoms. Analyses were performed using the crude model and doubly robust estimation. RESULTS: Forty-two healthy donors participated from January 2021 to July 2022. Case distribution (Cohort A: Cohort B) stood at 3:7 (Grade 1), 2:2 (Grade 2), and 1:0 (Grade 3); no Grade 4 cases were identified. There was no statistical significance in the incidence of Grade 1 or higher and Grade 3 citrate-related symptoms. DISCUSSION: The cumulative incidence of citrate-related side effects was less pronounced than in the previous research. This could stem from absence of blinding, and the decision to administer calcium drinks to the untreated group upon symptom detection. Although preemptive oral calcium intake before peripheral blood progenitor cell apheresis is not wholly effective, providing calcium-rich beverages to symptomatic donors may stave off symptom intensification.

Impact of oral health on the quality of life of public servants: an analysis of associated factors.

Introduction: Oral health encompasses functional and aesthetic aspects that directly impact an individual's daily activities. Objectives: To analyze the impact of oral health conditions and related factors on the quality of life of public servants. Methods: This cross-sectional study was conducted with a sample of 89 public servants, both permanent and outsourced, from a federal public university in northeastern Brazil. Outcome was the impact of oral health on daily activities, determined by the Oral Impacts on Daily Performance indicator, and independent variables were sociodemographic characteristics, normative oral health conditions, access to and use of dental services, self-reported oral morbidity, self-perception of oral health, and absenteeism because of dental reasons. All data were analyzed using descriptive and analytical statistics, using the chi-squared test for heterogeneity and linear trend. The significance level used was set at 5%, with a 95% CI. Results: Participants experienced at least one day of work impaired by dental problems in the six months prior to the survey. Prevalence of dental absenteeism was 7.9%. Variables associated with the impact of oral health on daily activities included gender, toothache, toothache intensity, self-reported oral health, awake bruxism, self-reported need for dentures, number of natural teeth in the upper and lower arches, and signs of temporomandibular dysfunction. Conclusions: Sociodemographic, clinical, and subjective oral health variables influence the impact of oral health on the daily activities of public servants.

Conclusões: Variáveis sociodemográficas, clínicas e subjetivas em saúde bucal influenciam o impacto da saúde bucal nas atividades diárias de servidores públicos.

Saliva metabolomics: concepts and applications in oral disorders.

OBJECTIVES: The purpose of this review was to present the basic concepts of metabolomics methodology and the use of saliva for diagnostic, prognostic, and predictive strategies. MATERIAL AND METHODS: This review followed the focus in: "saliva metabolomics" and "oral diseases". The authors searched studies on PubMed database. The inclusion criteria were original studies and reviews that assessed metabolomics techniques. A descriptive analysis was performed considering the study design, approach system, clinical steps, and tools for the determination of profile or biomarkers metabolites, and the advantages and disadvantages. RESULTS: Metabolomic analyses use a combination of analytical instrumentation and informatic tools to provide information on metabolite characteristics. In this review we described different technologies applied and the advantages and limitations of each technique. Furthermore, in the literature search, we retrieved 25 studies that investigated saliva metabolites in oral diseases: 8 studies used targeted analysis and 17 untargeted metabolomics approaches. Most studies included patients with periodontal diseases, oral squamous cell carcinoma, and Sjögren Syndrome. The most frequently reported metabolites were glycine, leucine, phenylalanine, dipeptides, linoleic acid, arachidonic acid, tyrosine, choline, taurine, lactate, valine, and proline. CONCLUSIONS: Metabolomics analysis has emerged as a powerful tool for tumor diagnosis and to enhance tumor classification, including salivary gland tumors (SGTs). It also holds promise for developing personalized treatment plans and defining more precise prognostic categories. CLINICAL RELEVANCE: Metabolomics is the most functional and comprehensive technique for monitoring and understanding gene functions and identifying the biochemical state of an organism in response to genetic and environmental changes.

Salivary proteins modulate Candida albicans virulence and may prevent oropharingeal candidiasis.

Oral candidiasis can be presented in different ways due to the virulence factors of its etiology such as Candida albicans that have developed an effective set of these factors that are able to improve its pathogenesis. The role of salivary immunological components in the development of candidiasis can provide insights for the development of new methodologies aiming to control this disease. The aim of this study was to evaluate the antifungal activity of two salivary components, histatin 5 and lactoferrin on C. albicans viability and virulence using a fluconazole resistant C. albicans clinical strain. Results showed that histatin 5 and lactoferrin decreased cell viability, and the cell surface hydrophobicity was increased by 18% in presence of 151 µg/mL of histatin 5 but was not altered by lactoferrin. It was observed the reduction of 69.3% in the expression of mannoproteins on C. albicans surface in the presence of 151 µg/mL of histatin, but proteolytic activity of serine proteinases was not inhibited by any of the proteins. Histatin 5 altered cell ultrastructure predominantly in the cytoplasmic compartment. However, this peptide does not interfere with mitochondrial function neither in membrane permeability of the yeasts. The association index between C. albicans and epithelial cells was increased by 51% in presence of 151 µg/mL of histatin. Results suggest that histatin 5 and lactoferrin affects viability and virulence of C. albicans at physiological levels, and the maintenance of these levels may be essential in the prevention of oropharyngeal candidiasis. Exogenous administration of these proteins may become a therapeutic alternative for resistant strains of C. albicans, circumventing toxicity issues, considering their constitutive features.

Tooth loss from the perspective of studies employing a life course approach: a systematic review.

The life course approach scrutinizes factors that shape the development of diseases over time. Tooth loss, which is influenced by social, behavioral and biological factors, can occur at various stages of life and tends to become more prevalent in later years. This systematic review examined the influence of socioeconomic, psychosocial, biological and behavioral adversities in life on the likelihood of tooth loss. Searches were conducted in the Embase, PubMed, Web of Science, Ovid, PsycINFO, Scopus and LILACS databases. Reference management was performed using EndNote online. The risk of bias was appraised using the Newcastle-Ottawa Scale (NOS). The electronic searches yielded 1366 records, 17 of which (13 cohort and four cross-sectional studies) met the inclusion criteria. According to the NOS, all studies had a low risk of bias. Two studies found a link between a lower education and higher incidence of tooth loss and socioeconomic status exerted a significant influence in 47% of the studies. Disadvantaged socioeconomic trajectories and health-related factors, such as smoking, general health perception and oral health behaviors, increased the likelihood of tooth loss. Factors such as dental visits, a history of toothache and exposure to fluoridated water influenced the likelihood of tooth loss. Individuals who experienced adversities in socioeconomic, behavioral and biological aspects throughout their life course were more prone to tooth loss.

Is galactomannan a useful tool for triage and diagnosis of oral invasive aspergillosis?

OBJECTIVE: To evaluate the accuracy of the galactomannan serum test in diagnosing oral invasive aspergillosis. METHODS: This prospective observational study included oncohematological neutropenic patients with suspected invasive aspergillosis, but without signs of pulmonary involvement. These patients underwent nasofibroscopy, biopsy, galactomannan serum testing, and maxillofacial high-resolution computed tomography to diagnose invasive aspergillosis. Patients were divided into two groups: Group 1 consisted of those with proven invasive aspergillosis, while Group 2 included patients without proven invasive aspergillosis. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS: Thirteen patients were included in Group 1 and four in Group 2. The sensitivity, specificity, positive predictive and negative predictive values were 0.69, 1.0, 1.0 and 0.5, respectively. Sensitivity was higher in cases with Aspergillus sinusitis than in cases with exclusive oral lesions (0.77 versus 0.5, respectively). The galactomannan serum test optical density index was higher in Group 1 (2.4; range 0.2-3.5) than in Group 2 (0.2; range: 0.1-0.3; P-value = 0.007. CONCLUSIONS: The galactomannan serum test is a valuable tool for screening invasive aspergillosis, especially in cases with nasal or sinus involvement, but biopsy is still the gold standard for diagnosis.
