Dental caries and developmental defects of enamel in cerebral palsy: A meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to compare the occurrence of dental caries and developmental defects of enamel (DDE) in individuals with and without cerebral palsy (CP). MATERIALS AND METHODS: We conducted searches across five databases and the grey literature. Data were organized using EndNote 20. Reporting followed the MOOSE checklist. A random-effects model meta-analyses were conducted using RStudio, presenting results as mean difference (MD), odds ratio (OR), and 95% confidence interval (CI). The risk of bias of studies was analyzed using the Newcastle-Ottawa Scale, and the certainty of evidence was assessed using GRADE. RESULTS: Among 1336 identified records, 25 studies involving 59,997 participants (mean age: 11.1 years) were included. Data of 12 were pooled into meta-analyses. No significant differences were found between CP and non-CP individuals across indices: DMFT (k = 7) (MD = 0.31; 95% CI [-0.42-1.05]), dmft (k = 4) (MD = 0.31; 95% CI [-0.50-1.14]), DMFS (k = 2) (MD = -0.61; 95% CI [-20.56-19.33]), dmfs (k = 3) (MD = 0.54; 95% CI [-1.09-2.17]), and DDE (k = 3) (OR = 0.80, 95% CI [0.09-7.31]). The certainty of evidence was very low. CONCLUSION: Individuals with CP do not appear to differ significantly from those without CP in terms of dental caries experience and DDE.

Contextual and individual determinants of oral health-related quality of life among adolescents.

The aim of this study was to assess the factors associated with oral health-related quality of life in adolescents (OHRQoL). Individual data on adolescents were collected from a secondary database. OHRQoL was measured using the oral impact on daily performance (OIDP) scale. Individual- and city-level variables were selected to represent the structural and intermediate determinants of health. The individual covariates analyzed were sex, age, skin color, maternal education, household income, number of people per room in the housing unit, dental attendance, self-perception of dental needs, untreated dental caries, and gingival bleeding. The contextual variables included the allocation factor, the Human Development Index (HDI), Gini coefficient, illiteracy, unemployment, income, average number of emergency dental visits per inhabitant, access to a sanitary sewer system, garbage collection, primary health care coverage, oral health team coverage, and number of tooth extractions between selected dental procedures and supervised toothbrushing. Unadjusted and adjusted multilevel Poisson regression analyses were used to evaluate the relationship between contextual and individual variables with overall OIDP scores (STATA version 16.0) - rate ratio (RR) and 95%CI. The mean OIDP score was 0.72 and the prevalence was 31.8%. There was an association between supervised toothbrushing average and the outcome (RR 0.95; 95%CI 0.91­0.99). Moreover, adolescents who lived in municipalities with the highest average number of emergency dental visits per inhabitant showed a higher OIDP. Sex, maternal education, untreated dental caries, and gingival bleeding were associated with OIDP. In addition, intersectoral public policies focusing on the reduction of social inequalities should be on the agenda of policymakers and stakeholders.

Photochemical outcomes triggered by gold shell-isolated nanorods on bioinspired nanoarchitectonics for bacterial membranes.

Boosted by the indiscriminate use of antibiotics, multidrug-resistance (MDR) demands new strategies to combat bacterial infections, such as photothermal therapy (PTT) based on plasmonic nanostructures. PTT efficiency relies on photoinduced damage caused to the bacterial machinery, for which nanostructure incorporation into the cell envelope is key. Herein, we shall unveil the binding and photochemical mechanisms of gold shell-isolated nanorods (AuSHINRs) on bioinspired bacterial membranes assembled as Langmuir and Langmuir-Schaefer (LS) monolayers of DOPE, Lysyl-PG, DOPG and CL. AuSHINRs incorporation expanded the isotherms, with stronger effect on the anionic DOPG and CL. Indeed, FTIR of LS films revealed more modifications for DOPG and CL owing to stronger attractive electrostatic interactions between anionic phosphates and the positively charged AuSHINRs, while electrostatic repulsions with the cationic ethanolamine (DOPE) and lysyl (Lysyl-PG) polar groups might have weakened their interactions with AuSHINRs. No statistical difference was observed in the surface area of irradiated DOPE and Lysyl-PG monolayers on AuSHINRs, which is evidence of the restricted nanostructures insertion. In contrast, irradiated DOPG monolayer on AuSHINRs decreased 4.0 % in surface area, while irradiated CL monolayer increased 3.7 %. Such results agree with oxidative reactions prompted by ROS generated by AuSHINRs photoactivation. The deepest AuSHINRs insertion into DOPG may have favored chain cleavage while hydroperoxidation is the mostly like outcome in CL, where AuSHINRs are surrounding the polar groups. Furthermore, preliminary experiments on Escherichia coli culture demonstrated that the electrostatic interactions with AuSHINRs do not inhibit bacterial growth, but the photoinduced effects are highly toxic, resulting in microbial inactivation.

Factors associated with toothache in 12-year-old adolescents in a southeastern state of Brazil.

This cross-sectional study evaluated factors associated with toothache in 12-year-old adolescents from the state of Minas Gerais in Brazil. Secondary data were collected from the SB Minas Gerais 2012 epidemiological survey. The dependent variable was toothache in the past 6 months. The independent variables were grouped into two levels: individual (sex, ethnic group, family income, periodontal condition, dental caries, dental treatment needs, and type of service used) and contextual (allocation factor, Human Development Index, Gini coefficient, gross domestic product, unemployment, illiteracy, basic sanitation, garbage collection, family income, half or a quarter of a minimum wage, primary healthcare coverage, primary oral healthcare team coverage, oral health technician, access to individual dental care, and supervised tooth brushing). A multilevel analysis was performed using the Hierarchical Linear and Nonlinear Modeling Software Program to assess the association of individual and contextual variables with toothache in the last 6 months. The prevalence of toothache in the last six months among the adolescents of this study was 19.1%. An association was found with family income (p <0.001), dental caries (p <0.001), primary oral healthcare team coverage (p = 0.015) and oral health technician (p = 0.008). Socioeconomic conditions and the most prevalent oral diseases, such as dental caries, as well as the use of public services, were related to toothache in adolescents aged 12 years. These findings reinforce the need to develop and implement public policies to address the oral health problems of this population.

Characterization of a virulence-modifying protein of Leptospira interrogans identified by shotgun phage display.

Pathogenic species of Leptospira are etiologic agents of leptospirosis, an emerging zoonotic disease of worldwide extent and endemic in tropical regions. The growing number of identified leptospiral species sheds light to their genetic diversity and unique virulence mechanisms, many of them still remain unknown. Toxins and adhesins are important virulence factors in several pathogens, constituting promising antigens for the development of vaccines with cross-protection and long-lasting effect against leptospirosis. For this aim, we used the shotgun phage display technique to unravel new proteins with adhesive properties. A shotgun library was constructed using fragmented genomic DNA from Leptospira interrogans serovar Copenhageni strain Fiocruz L1-130 and pG8SAET phagemid vector. Selection of phages bearing new possible cell-binding antigens was performed against VERO cells, using BRASIL biopanning methodology. Analysis of selected clones revealed the hypothetical protein LIC10778, a potentially exposed virulence factor that belongs to the virulence-modifying (VM) protein family (PF07598), composed of 13 members in the leptospiral strain Fiocruz L1-130. Prediction of LIC10778 tertiary structure indicates that the protein contains a cellular-binding domain (N-terminal portion) and an unknown domain of no assigned activity (C-terminal portion). The predicted N-terminal domain shared structural similarities with the cell-binding and internalization domain of toxins like Ricin and Abrin, as well as to the Community-Acquired Respiratory Distress Syndrome (CARDS) toxin in Mycoplasma pneumoniae. Interestingly, recombinant portions of the N-terminal region of LIC10778 protein showed binding to laminin, collagens I and IV, vitronectin, and plasma and cell fibronectins using overlay blotting technique, especially regarding the binding site identified by phage display. These data validate our preliminary phage display biopanning and support the predicted three-dimensional models of LIC10778 protein and other members of PF07598 protein family, confirming the identification of the N-terminal cell-binding domains that are similar to ricin-like toxins. Moreover, fluorescent fused proteins also confirmed that N-terminal region of LIC10778 is capable of binding to VERO and A549 cell lines, further highlighting its virulence role during host-pathogen interaction in leptospirosis probably mediated by its C-terminal domain. Indeed, recent results in the literature confirmed this assumption by demonstrating the cytotoxicity of a closely related PF07598 member.

Malocclusion characteristics amongst individuals with autism spectrum disorder: a systematic review and meta-analysis.

BACKGROUND: To estimate the prevalence of malocclusion in individuals with autism spectrum disorders (ASD) and to assess the relationship between ASD and malocclusion. METHODS: We searched electronic databases including PubMed, Scopus, Web of Science, Cochrane, Embase, SciELO LILACS, Proquest, OpenGrey and Google Scholar. There were no language or publication dates restrictions. Two researchers independently performed selection, data extraction and quality assessment. Quality assessment and risk of bias were evaluated through the Newcastle-Ottawa scale and ROBINS-E tool. Meta-analyses using random effect models were used to estimate pooled measures of prevalence of malocclusion characteristics in individuals with ASD and pooled odds ratio (OR) on the relationship between ASD and malocclusion characteristics. Subgroup meta-analyses were conducted according to children and adolescents, history of orthodontic treatment, and occurrence of other syndromes and medical conditions. RESULTS: Searching identified 5549 papers with 238 were selected for full assessment. Eighteen cross-sectional studies were included according to inclusion criteria. Of them, eleven studies were considered of moderate quality. A judgement of critical risk of bias occurred for thirteen studies. The most prevalent malocclusion characteristics in individuals with ASD were crowding (33%; 95% CI 22 to 44%) and increased maxillary overjet (39%; 95% CI 23 to 54%). Individuals with ASD had higher odds of Angle's Class II (OR 1.92; 95% CI 1.36 to 2.72), Angle's Class III (OR 2.33; 95% CI 1.29 to 4.23), open bite (OR 1.96; 95% CI 1.21 to 3.16), and increased maxillary overjet (OR 1.53; 95% CI 1.06 to 2.21) than individuals without ASD. CONCLUSIONS: Angle's Class II, Angle's Class III, anterior open bite and increased maxillary overjet were more prevalent in individuals with ASD than those without ASD. Further high-quality studies are needed.

On the caveats of a multiplex test for SARS-CoV-2 to detect seroconversion after infection or vaccination.

The Covid-19 pandemic, caused by SARS-CoV-2, has resulted in over 6 million reported deaths worldwide being one of the biggest challenges the world faces today. Here we present optimizations of all steps of an enzyme-linked immunosorbent assay (ELISA)-based test to detect IgG, IgA and IgM against the trimeric spike (S) protein, receptor binding domain (RBD), and N terminal domain of the nucleocapsid (N-NTD) protein of SARS-CoV-2. We discuss how to determine specific thresholds for antibody positivity and its limitations according to the antigen used. We applied the assay to a cohort of 126 individuals from Rio de Janeiro, Brazil, consisting of 23 PCR-positive individuals and 103 individuals without a confirmed diagnosis for SARS-CoV-2 infection. To illustrate the differences in serological responses to vaccinal immunization, we applied the test in 18 individuals from our cohort before and after receiving ChAdOx-1 nCoV-19 or CoronaVac vaccines. Taken together, our results show that the test can be customized at different stages depending on its application, enabling the user to analyze different cohorts, saving time, reagents, or samples. It is also a valuable tool for elucidating the immunological consequences of new viral strains and monitoring vaccination coverage and duration of response to different immunization regimens.

Saccharomyces boulardii exerts renoprotection by modulating oxidative stress, renin angiotensin system and uropathogenic microbiota in a murine model of diabetes.

AIMS: We aimed to investigate whether Saccharomyces boulardii strain might exert renoprotective effects by modulating renal renin angiotensin system, oxidative stress and intestinal microbiota in streptozotocin-diabetic mice. MAIN METHODS: Thirty-six C57BL/6 male mice were divided into four groups: control (C), control + probiotic (CP), diabetes (D), diabetes + probiotic (DP). Diabetes was induced by one intraperitoneal injection of streptozotocin and Saccharomyces boulardii was administered by oral gavage for 8 weeks. Blood glucose, albuminuria and urinary volume were measured. Renal levels of angiotensin peptides (angiotensin I, II and 1-7) and the activities of angiotensin-converting enzyme (ACE) and ACE2 were determined, besides that, renal morphology, serotonin and dopamine levels and also microbiota composition were analyzed. KEY FINDINGS: Probiotics significantly increased C-peptide secretion and reduced blood glucose of diabetic animals. Saccharomyces boulardii also improved renal antioxidant defense, restored serotonin and dopamine concentration, and activated the renin-angiotensin system (RAS) vasodilator and antifibrotic axis. The modulation of these markers was associated with a beneficial impact on glomerular structure and renal function of diabetic treated animals. The phenotypic changes induced by Saccharomyces boulardii were also related to modulation of intestinal microbiota, evidenced by the decreased abundance of Proteus and Escherichia-Shigella, considered diabetic nephropathy biomarkers. SIGNIFICANCE: Therefore, probiotic administration to streptozotocin-induced diabetic mice improves kidney structure and function in a murine model and might represent a reasonable strategy to counteract nephropathy-associated maladaptive responses in diabetes.

Oral health issues in children and adolescents with vision impairment: A systematic review and meta-analysis.

BACKGROUND: Children and adolescents with vision impairment (VI) may be at increased risk of oral health issues, such as periodontal inflammation, poor oral hygiene, dental caries, and dental trauma, but this is inconclusive in the literature. AIM: To systematically review the literature to determine the main oral health issues of children and adolescents with VI compared to those without VI. DESIGN: Electronic and manual searches were performed to identify observational studies involving children and adolescents with and without VI, to determine and compare their oral health issues. The methodological quality was assessed using the Joanna Briggs Institute critical appraisal tool. Studies that had homogeneity of methods were incorporated into meta-analyses. RESULTS: Fifteen cross-sectional studies were included. Overall, most studies presented methodological flaws and high risk of bias. The meta-analysis showed that children and adolescents with VI were 3.86 times as likely to exhibit dental trauma (OR = 3.86, 95% CI = 2.63-5.68, I2  = 0%) and had higher/poorer values for plaque (MD = 0.80, 95% CI = 0.58-1.02, I2  = 96%), gingivitis (MD = 0.69, 95% CI = 0.02-1.37, I2  = 100%), calculus (MD = 0.04, 95% CI = 0.03-0.06, I2  = 0%), and oral hygiene indices (MD = 0.71, 95% CI = 0.24-1.18, I2  = 97%), as well as DMFS (MD = 0.90, 95% CI = 0.68-1.13, I2  = 26%). CONCLUSION: Across a wide array of assessments, children and adolescents with vision impairment had worse oral health outcomes than those without VI.

Hematological and histopathological evaluation of meat-type quails fed Madagascar cockroach meal.

Aiming at the sustainability of meat production, insects can replace traditional ingredients in the diet of poultry. Studies evaluating performance in birds have emerged to ensure this ability, but few address the health parameters of animals. This study was carried out to evaluate the effects of the inclusion of Madagascar cockroach meal in traditional diets on hematological and histopathological traits of meat-type quails. The inclusion of Madagascar cockroach meal in the diet was evaluated in four levels: 0%, 6%, 12%, and 18%. Observations for hematological and histopathological traits from 6 repetitions on each group were recorded for both sexes at 35 days of age. Hematological parameters were not influenced by Madagascar cockroach inclusion on diet and quail's sex. Red and white blood cells count were within the normal range for poultry. No significant findings were observed during the histopathological evaluation of the pancreas, duodenum, jejunum, and ileum. Liver fatty degeneration was visualized in all treatments in the same intensity. Quail's diets containing up to 18% insect meal during the growth period did not affect the studied health parameters, so the Madagascar cockroach meal could be considered as an alternative to a protein ingredient for poultry production.

Occurrence of bruxism in individuals with autism spectrum disorder: A systematic review and meta-analysis.

AIMS: To investigate bruxism in individuals with autism spectrum disorder (ASD) and neurotypical individuals. METHODS AND RESULTS: Searches were conducted in the MedLine via Ovid, Embase via Ovid, Cochrane Database of Systematic Reviews, Scopus, Web of Science, Latin American and Caribbean Health Sciences (LILACS), Brazilian Library of Dentistry (BBO) and SciELO databases, grey literature and a hand search up to December 2020 with no restrictions imposed regarding language or year of publication (CRD42020211307). For the meta-analysis, the frequency of bruxism was extracted, with the calculation of odds ratios (OR) and 95% confidence intervals (CI) using a random effects model in RevManager. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Seventeen case-control studies were included in the qualitative synthesis and 15 were included in the meta-analysis, totaling a population of 3850 individuals. The ASD group was more likely to develop bruxism than the controls (OR: 3.80; 95% CI: 2.06-7.01). The certainty of the evidence was classified as "very low" for the occurrence of bruxism between ASD and control individuals. CONCLUSION: It is uncertain whether individuals with ASD are more likely to have bruxism than healthy controls.

The accuracy of Fetoplacental Doppler in distinguishing between growth restricted and constitutionally small fetuses.

INTRODUCTION: Fetoplacental Doppler is considered to be a key tool for the diagnosis of placenta-mediated fetal growth restriction(FGR). We aimed to determine the diagnostic accuracy of fetoplacental Doppler for specific placental diseases. METHODS: A retrospective cohort study of all women with a singleton pregnancy and an antenatal diagnosis of SGA fetus(estimated fetal weight <10th centile for gestational age), who underwent fetoplacental Doppler assessment within 2 weeks before birth. Primary exposure was any abnormal Doppler result, defined as an abnormal umbilical artery(UA) Doppler, middle cerebral artery(MCA) Doppler, cerebroplacental-ratio(CPR), or umbilico-cerebral ratio(UCR). Study outcomes were abnormal placental pathology: maternal vascular malperfusion(MVM), villitis of unknown etiology(VUE), or fetal vascular malperfusion(FVM). RESULTS: A total of 558 women with a singleton SGA fetus were included, of whom 239(42.8%) had an abnormal fetoplacental Doppler findings. UA Doppler had the lowest detection rate for abnormal placental pathology. MCA Doppler exhibited a significantly higher detection rate for all types of pathology. CPR and UCR exhibited highest detection rates for all types of placental pathology, however, were also associated with the highest false positive rate. The combination of fetoplacental Doppler with the severity of SGA and maternal hypertensive status achieved a high negative predictive value MVM lesions(97%). In contrast, fetoplacental Doppler did not improve the negative predictive value for non-MVM pathology(VUE or FVM). DISCUSSION: Among SGA fetuses, the combination of UA and MCA Doppler is highly accurate in ruling out FGR due to MVM placental pathology, but is of limited value in excluding FGR due to underlying non-MVM pathologies.

Relato de experiência: grupo de aconselhamento pastoral para pessoas em processo de luto em tempos de pandemia da COVID-19 / Experience report: Pastoral counseling group for grieving people in times of COVID-19 pandemic / Relato de experiencia: grupo de consejería pastoral para personas en proceso de duelo en tiempos de pandemia de COVID-19

INTRODUÇÃO: A elaboração do luto é vivenciada de formas particulares pelas pessoas, dependendo dos recursos sociais e pessoais disponíveis, do contexto e da história de vida do indivíduo. Este trabalho propõe-se a apresentar uma iniciativa de assistência às pessoas enlutadas através do aconselhamento pastoral. OBJETIVO: O objetivo desta intervenção é oferecer suporte a pessoas que estejam vivenciando o luto, através da partilha de experiência ante a dor e sofrimento diante da morte. METODOLOGIA: A metodologia dos grupos é aplicada em dois módulos nos quais cada grupo tem cerca de quatro encontros por mês, com encontros semanais. Nestes encontros, que tem uma duração de até 1h30min, são trabalhados temas que possibilitem diálogo e troca de experiências diante do luto. Os grupos são compostos por, no mínimo cinco e, no máximo dez pessoas. Até o momento, foram atendidas cerca de 70 pessoas. RESULTADOS E DISCUSSÕES: Os resultados dessa intervenção revelam que o grupo se tornou um espaço de ressignificação da vida, pós-perda para morte. Por tratar-se de um momento de compartilhamento de dores e lutos, as experiências trocadas mostraram caminhos para a assimilação do próprio luto e desenvolvimento de projetos de vida. O presente projeto teve seu início antes da Pandemia de COVID-19, entretanto, a assistência se fez presente durante este período. Especialmente com peculiaridades relacionadas a um velório restrito e limitações para elaboração do luto por meio de rituais socialmente reconhecidos. CONSIDERAÇÕES FINAIS: Consideramos que o simples fato de refletir sobre os assuntos abordados a cada encontro, ao mesmo tempo em que exerce a escuta e pode falar sobre suas próprias experiências, por si só, se revela como caminho para a superação do luto.

INTRODUCTION: The elaboration of mourning is experienced in particular ways by people, depending on social and personal available resources, context, and life history. This work aims to present a support initiative to mourning people through pastoral counseling. OBJECTIVES: The goal of this intervention is to offer support to people who are experiencing grief, through the sharing of experience in the face of pain and suffering in the face of death. METHOD: The groups' methodology is applied in two modules, in which each group has about four meetings per month, with weekly meetings. In these meetings, which last up to 1h30min, topics that allow dialogue and exchange of experiences in the face of grief are worked on. The groups are composed of a minimum of five people and a maximum of ten. Until this moment, seventy people have been assisted. RESULTS AND DISCUSSION: The results of this intervention reveal that the group becomes a space of resignification of life after death losses. As it is a time for sharing the pain of mourning, experiences exchanged showed ways to assimilate one's own grief and develop life projects. This project started before the COVID-19 pandemic. However, this assistance stills remains present during this time. The results of these realities present peculiarities related to the restricted funeral and limitations to the elaboration of mourning through socially recognized rituals. FINAL CONSIDERATIONS: It is observed that the simple fact of reflecting on subjects addressed in each meeting, at the same time that it is possible to listen and share your own experiences, reveals itself as a way of overcoming grief.

El presente proyecto tuvo su inicio antes de la Pandemia de COVID-19, pero la asistencia se hizo presente durante este periodo. Especialmente con peculiaridades relacionadas a un velorio restricto y limitaciones para la elaboración del luto por medio de rituales conocidos socialmente. CONSIDERACIONES FINALES: Consideramos que el simple hecho de reflexionar sobre los asuntos abordados en cada encuentro, además de ejercer la escucha y poder hablar de las propias experiencias, también se revela como un camino para la superación del duelo.

Oral mucosal lesions in pregnant women: A population-based study.

OBJECTIVE: To evaluate the prevalence of oral mucosal lesions (OML) and oral self-examination and their associated factors among pregnant women from the 2015 Pelotas Birth Cohort Study, Brazil. METHODS: Pregnant women who would deliver babies in 2015 were included in the antenatal study. Data related to demographic, socio-economic and behavioural conditions were collected using questionnaires. Participants were also clinically assessed for oral health outcomes. The outcomes were the presence of OMLs and oral self-examination. Size, location, time of onset and symptomatology of the lesions were collected. Descriptive and bivariate analysis, and Poisson regression were performed. p-Value <0.05 was set to indicate statistical significance. RESULTS: Data from 2481 pregnant women were analysed. Four hundred and nine (16.5%) had at least one OML. The most prevalent lesions were exostosis (80/16.6%), coated tongue (70/14.5%) and benign oral brownish pigmentation (68/14.1%). Non-white skin colour was associated with a higher prevalence of OMLs (PR 1.3; 95% CI 1.1-1.6), while daily use of dental floss was positively associated with the prevalence of oral self-examination (PR 1.4; 95% CI 1.2; 1.5). CONCLUSIONS: Almost 20% of pregnant women presented OML, which were more prevalent in non-white individuals. Women with better oral care were more likely to perform oral self-examination.

Photobiomodulation-blue and red LED: protection or cellular toxicity? In vitro study with human fibroblasts.

Photobiomodulation is widely used in clinical practice, and there is increasing interest in using this tool to treat numerous dysfunctions in living organisms. Therefore, this study aimed to verify the action of blue and red light-emitting diode light in cells. Human fibroblast cell line (HFF-1) were irradiated by blue (470 nm) or red (658 nm) light at doses of 4 and 18 J/cm2, respectively. Laboratory analyses were carried out to check for viability, proliferation, cell death, and the formation of reactive oxygen and nitric oxide species. The blue light demonstrated cell protection potential by reducing free radical formation and protecting the cell membrane by decreasing double-stranded DNA strands. On the other hand, the red light showed less potential for cell protection due to the risk of associating more significant nitric oxide formation with increased reactive oxygen species formation, in addition to having a greater amount of extracellular DNA. Cell damage prevention is a potential beneficial effect of blue light at 18 J/cm2. Despite the consolidated effects of red light in treating wounds, there was a potential toxic effect of this wavelength in the doses studied. Given the above, new studies relating these parameters with pathological cells or aggressors that simulate damage may offer results that can better support clinical practice.

Malocclusion in individuals with osteogenesis imperfecta: A systematic review and meta-analysis.

OBJECTIVE: To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI. MATERIALS AND METHODS: Searches in PubMed, Ovid, Web of Science, Scopus, Lilacs and gray literature were performed. Data extraction was conducted by two researchers. Risk of bias assessment employing the Newcastle-Ottawa Scale and meta-analysis were conducted. Results were provided with mean difference (MD), odds ratio (OR) and 95% confidence interval (CI). Strength of evidence was determined. RESULTS: Six cross-sectional studies were included. In comparison with individuals without OI, the group with OI had 19.69-fold greater chance of exhibiting Angle Class III malocclusion (OR = 19.69, CI: 9.00-43.09) and presenting anterior crossbite greater (MD = 6.08, CI: 2.40-9.77). Individuals without OI had a significantly greater ANB angle (MD = 3.88, CI: 1.15-6.61) and SNA angle (MD = 2.11, CI: 0.24-3.98) in comparison with those with OI. No difference between groups was found for SNB (MD = -0.50, CI: -2.21 to 1.21) and open bite (MD = 0.98, CI: -0.29 to 2.25). Most studies included had moderate methodological quality. Strength of evidence was low or very low. CONCLUSIONS: The occurrence of Angle Class III malocclusion and anterior crossbite was greater among individuals with OI compared to those without OI. These findings can assist stakeholders about the occlusal abnormalities affecting OI individuals.

Factors associated with toothache in 12-year-old adolescents in a southeastern state of Brazil

Abstract: This cross-sectional study evaluated factors associated with toothache in 12-year-old adolescents from the state of Minas Gerais in Brazil. Secondary data were collected from the SB Minas Gerais 2012 epidemiological survey. The dependent variable was toothache in the past 6 months. The independent variables were grouped into two levels: individual (sex, ethnic group, family income, periodontal condition, dental caries, dental treatment needs, and type of service used) and contextual (allocation factor, Human Development Index, Gini coefficient, gross domestic product, unemployment, illiteracy, basic sanitation, garbage collection, family income, half or a quarter of a minimum wage, primary healthcare coverage, primary oral healthcare team coverage, oral health technician, access to individual dental care, and supervised tooth brushing). A multilevel analysis was performed using the Hierarchical Linear and Nonlinear Modeling Software Program to assess the association of individual and contextual variables with toothache in the last 6 months. The prevalence of toothache in the last six months among the adolescents of this study was 19.1%. An association was found with family income (p <0.001), dental caries (p <0.001), primary oral healthcare team coverage (p = 0.015) and oral health technician (p = 0.008). Socioeconomic conditions and the most prevalent oral diseases, such as dental caries, as well as the use of public services, were related to toothache in adolescents aged 12 years. These findings reinforce the need to develop and implement public policies to address the oral health problems of this population.
