Systematic review: Impact of parental decision on paediatric COVID-19 vaccination.

OBJECTIVE: The objective was to carry out a systematic review on the acceptance of parents to vaccinate their children against COVID-19 and the factors that contribute for vaccination hesitancy. METHODS: The Preferred Reporting Items for Systematic Re- views and Meta-Analyses (PRISMA) guidelines and the Patient, Intervention, Comparison and Outcome (PICO) strategy were followed. A search was carried out in the VHL Regional Portal, PubMed, Scielo, Web of Science, Embase and Scopus databases. We included articles that assessed the rate of acceptance and/or hesitation of parents and the factors that affect the decision about vaccination against COVID-19 for their children in cross-sectional studies. Laboratory studies, animal models, tests and case reports that elected other aspects related to COVID-19 were excluded. The methodological quality of the studies was based on the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data, developed by the Joanna Briggs Institute. RESULTS: From the 708 articles found, 237 studies remained after removal of duplicates. Titles and abstracts of these publications were evaluated and, applying the exclusion criteria, 56 articles were selected. Inclusion criteria were employed and 28 studies were eligible. Overall average vaccination acceptance rate was 55.81%, and the main reasons for vaccine hesitancy were uncertainty of vaccine efficacy and safety, concerns about side effects, and lack of access to relevant information. CONCLUSION: The research results can be useful for the development of health education and parental awareness strategies in order to promote greater adherence to vaccination against COVID-19.

Early Childhood Caries: Epidemiology, Severity and Sociobehavioural Determinants.

PURPOSE: To investigate the association between sociobehavioural variables and the pattern and severity of early childhood caries in Brazilian infants and toddlers ages 0-3 years. MATERIALS AND METHODS: This was a cross-sectional study with 768 children who attended 58 public nursery schools. Five previously calibrated teams (Kappa = 0.842) performed oral examinations, using the decayed, missing, filled teeth (dmft) index according to the WHO methodology. A pretested, self-administered questionnaire was given to the subjects' parents or guardians to obtain sociobehavioural information. RESULTS: Caries was observed in 134 of the 768 (17%) children. Caries and rampant caries were significantly more prevalent in low-income families (p = 0.0121) and the incidence of caries was associated with access to dental services (p < 0.05). The percentages of children who were caries free in the age groups of 0-11 months, 12-23 months, 24-35 months and 36-47 months were 100%, 96%, 88% and 76%, respectively. CONCLUSION: Programmes for prevention and oral health education should be instituted, preferably during the first year of life, especially for those in the most socioeconomically deprived groups.

Occurrence of socransky red complex in pregnant women with and without periodontal disease.

PURPOSE: To verify the presence of Socransky Red Complex (Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia) and P. intermedia using polymerase chain reaction (PCR) in periodontally healthy pregnant women and pregnant women with periodontal disease, as well as its relation to arterial blood pressure and capillary glycaemia. MATERIALS AND METHODS: This case control study included 86 pregnant women, including 50 pregnant women with healthy periodontium, 27 with gingivitis and 9 with periodontitis. Arterial blood pressure and glycaemia were evaluated and recorded. Clinical specimens from the gingival crevice or periodontal pockets were gathered with sterile absorbent paper cones. DNA extraction was accomplished using the Easy-DNA Kit test and the presence of bacteria was detected by PCR with primers and specific probes for each microorganism. RESULTS: The arterial pressure of all pregnant women was found to be within normal levels and 51% presented with hyperglycaemia, these two variables were not associated with periodontal conditions and/or presence of microorganisms. Socransky Red Complex was not present in pregnant women with healthy periodontium; however, it was present in pregnant women with gingivitis (3.7%) and in a higher percentage of pregnant women with periodontitis (33.3%). CONCLUSION: Socransky Red Complex was found only in cases of periodontal diseases and is not related to blood pressure and/or high levels of blood glucose.

Longitudinal study of habits leading to malocclusion development in childhood.

BACKGROUND: The increased prevalence of malocclusions represents a secular trend attributed to the interaction of genetic and environmental factors. The analysis of factors related to the causes of these changes is essential for planning public health policies aimed at preventing and clinically intercepting malocclusion. This study investigated the sucking habits, nocturnal mouth breathing, as well as the relation of these factors with malocclusion. METHODS: This is a longitudinal study in which 80 mother-child pairs were monitored from the beginning of pregnancy to the 30th month after childbirth. Home visits for interviews with the mothers were made on the 12th, 18th and 30th months of age. Finger sucking, pacifier sucking, bottle feeding, breastfeeding and nocturnal mouth breathing, were the variables studies. On the 30th month, clinical examinations were performed for overjet, overbite and posterior crossbite. A previously calibrated single examiner (Kappa coefficient = 0.92) was responsible for all examinations. Data were analyzed using the chi-squared or Fisher's exact tests, at a significance level of 5%. RESULTS: Bottle feeding was the most prevalent habit at 12, 18 and 30 months (87.5%; 90% and 96.25%, respectively). Breastfeeding was 40%, 25% and 12.50% at 12, 18 and 30 months, respectively. Nearly 70% of the children in this study had some sort of malocclusion. Pacifier sucking habit at 12, 18 and 30 months of age was associated with overjet and open bite; and at 30 months, an association with overbite was also observed. Finger sucking habit and breastfeeding at 12, 18 and 30 months were also associated with overjet and open bite. The posterior crossbite was associated with bottle feeding at 12 and 30 months, and nocturnal mouth breathers at 12 and 18 months. CONCLUSIONS: Sucking habits, low rates of breastfeeding, and nocturnal mouth breathing were risk factors for malocclusion.

COVID-19 and changes in dental practices in the Brazilian Public Health System: perception of the oral health team.

The aim of this study was to verify the perception of the oral health team regarding work safety and aspects related to changes in dental practices during the COVID-19 pandemic. A descriptive, exploratory, quantitative, and qualitative cross-sectional study was conducted using an electronic questionnaire sent via email to health professionals (n = 197) affiliated with the Brazilian Public Health System (SUS), from December 2020 to September 2021, in a municipality located in the northeast of the state of São Paulo, Brazil. The variables of interest were sociodemographic characteristics and those related to the professionals' perception of oral health care during the pandemic and its impact on these workers' occupational safety. Descriptive statistics were performed, and the absolute and relative frequencies of quantitative variables were calculated, whereas lexical analysis was performed for textual content using the descending hierarchical classification (CHD). Out of the total sample, elective and urgent/emergency care was provided by 58.95% (n = 56); physical barriers were absent between the teams in 54.74% (n = 52); minimally invasive techniques were applied in 71.58% (n = 68); personal protective equipment (PPE) was replaced in 81.05% (n = 77) between appointments; and occupational safety was reported by 49.47% (n = 47). Textual analysis showed a decrease in appointments and consultations, with a longer interval between appointments. The professionals noticed changes in dental practices during the pandemic, mainly regarding the use of PPE, the type of treatment performed, the number of treated patients, and the greater time interval between consultations. The physical infrastructure of health units and the availability of PPE to patients needed some adjustments. A significant number of workers felt safe in providing dental care during the pandemic.

Analysis of the Dental Caries Epidemiological Profile in Children of Benguela city, Angola.

PURPOSE: To analyse the epidemiological profile of dental caries in children aged 5 and 12 years in the city of Benguela, Angola. MATERIALS AND METHODS: This was an observational, analytical, cross-sectional study conducted in 2019 with 190 12-year-old schoolchildren and 240 5-year-old schoolchildren from the public education system in Benguela, Angola. The relationship between dental caries and dental characteristics, sociodemographic factors, access to dental services, oral hygiene practices, and eating habits was analysed. Dental condition was evaluated using the dmft and decayed, missing, and filled teeth (DMFT) indices. RESULTS: It was found that 62.63% (n = 119) of 12-year-old students and 42.08% (n = 101) of 5-year-old students were free from dental caries. The average DMFT was 0.76 + 1.35 and dmft was 2.19 + 2.95. The majority of children (56.51%) had never been to the dentist, had no dental elements restored, and none of the students used dental floss. The proportion of students who consumed sweets every day was higher at 5 years of age (46.25%) than at 12 years of age (22.63%). There was a statistically significant association (P = 0.01) between the higher incidence of dental caries and peri-urban location among 5-year-old schoolchildren. CONCLUSION: This study showed that the prevalence of dental caries in the permanent dentition of schoolchildren in Benguela is very low; however, the situation is critical in the primary dentition, especially in the peri-urban area. The limited access to dental surgeons and lack of treatment for affected teeth highlight the need to implement and develop public policies to promote oral health.

Malocclusion and its relationship with oral health-related quality of life in patients with eating disorders.

OBJECTIVE: To evaluate the prevalence and severity of malocclusion and its impact on oral health-related quality of life (OHRQoL) and self-reported satisfaction of patients with anorexia and bulimia nervosa. METHODS: The sample consisted of sixty women who attended a specialized mental health clinic of a Brazilian medical school. Participants were distributed into two groups: patients with anorexia and bulimia nervosa (ABN; n=30) and control patients without eating disorders (CN; n=30). The dental occlusion was evaluated by the Dental Aesthetic Index; the OHRQoL was assessed using the OHIP-14 questionnaire; and the self-reported satisfaction with the appearance of teeth, speech ability and chewing was obtained by interviews. RESULTS: Severe and very severe malocclusion were observed in 26.67% and 46.67% of patients in the ABN group, respectively, while the CN group showed 80.00% of patients without abnormality/mild malocclusion. ABN group showed a higher proportion of patients (p < 0.05) with tooth loss, spacing in the region of incisors, maxillary misalignment, and mandibular misalignment in relation to CN group. ABN group presented lower (p< 0.05) OHRQoL and self-reported satisfaction with the appearance of teeth, speech ability and chewing, compared to the CN group. There was a significant positive correlation (p< 0.05) between the Dental Aesthetic Index and OHIP-14 scores in the ABN group. CONCLUSIONS: The prevalence of severe malocclusion in ABN group was high, with a negative impact on OHRQoL and self-reported satisfaction with the chewing ability, speech ability and appearance of teeth.

Sickness absenteeism of Primary Health Care professionals before and during the COVID-19 pandemic.

OBJECTIVE: to identify the frequency of occurrence of sickness absenteeism, according to the profile of Primary Health Care (PHC) professionals, and verify if there was an impact of the pandemic on absence duration and reason. METHODS: a cross-sectional study, from January/2019 to December/2020, with PHC professionals from a municipality in northeastern São Paulo. Descriptive statistics were performed, with frequency calculation. RESULTS: of the 977 PHC professionals, 633 (64.79%) used a medical certificate to justify their absence from work in 2019, and 837 (85.67%) in 2020. The main reason for leave was diseases of the musculoskeletal system and connective tissue in the two years. The mean duration of leave was 7.33 days (SD=17.33) in 2019 and 9.88 days (SD=16.05) in 2020. Nursing assistants were the ones who took the most leave in both years. CONCLUSIONS: there was an impact of the pandemic on absence duration and reason.

Knowledge and attitude of women with high-risk pregnancy about the Zika virus transmission. / Conhecimento e atitude das gestantes de alto risco sobre a transmissibilidade do vírus zika.

Objective was to analyze the knowledge and attitude of high risk pregnant women about zika. This is a cross-sectional study, quantitative, with a sample of 201 high risk women who perform prenatal the Ambulatory Medical Specialties. A self-administered instrument, was applied after consultation with the doctor. Inclusion criteria were the presence of pregnant women on the day of the interview and their consent to participate. Exclusion criteria were those who did not agree to participate and were not performing prenatal care during the study period. For the data analysis we used chi square and fisher exact, in software Epi info 7.1 and Bioestat 5.0. Of the pregnant women, 76% believed that their neighborhood was likely to be infected by the virus and used measures to control mosquito proliferation, such as not leaving standing water (n = 154). In relation to knowledge, there was an association between Zika and microcephaly (p≤ 0.0001) and the need for more information (p = 0.0439). To prevent infection, 76% took no action, there was an association between the need for knowledge about the subject and the actions taken to combat the virus (p = 0.0049). We conclude that pregnant women's knowledge and attitude about zika is failed.

Objetivou analisar o conhecimento e a atitude das gestantes de alto risco sobre a zika. Trata-se de um estudo transversal, quantitativo, com amostra de 201 gestantes de alto risco, que realizam pré-natal no Ambulatório Médico de Especialidades. Aplicou-se um instrumento auto administrado, aplicados após a consulta com o médico. Os critérios de inclusão utilizados foram a presença das gestantes no dia da entrevista e seu consentimento de participação. Os de exclusão as que não aceitaram participar e não estarem realizando o pré natal no período do estudo. Para análise de dados, utilizou-se qui-quadrado e exato de Fisher, nos softwares Epi info 7.1 e Bioestat 5.0. Das gestantes, 76% acreditavam que, em seu bairro, é provável a infecção pelo vírus e utilizam medidas para controlar a proliferação do mosquito, como não deixar água parada (n = 154). Em relação ao conhecimento, houve associação entre a zika e a microcefalia (p ≤ 0,0001) e o apontamento da necessidade de mais informações (p = 0,0439). Para impedir o contágio, 76% não tomaram nenhuma atitude; houve, ainda, associação entre a necessidade de conhecimento sobre o assunto e as ações realizadas no combate ao vírus (p = 0,0049). Conclui-se que o conhecimento e a atitude das gestantes sobre a zika é falho.

[Prenatal Information System: critical analysis of register in a municipality of São Paulo State]. / Sistema de Informação Pré-Natal: análise crítica de registros em um município paulista.

The prenatal assistance is one of the health care pillars. This study aimed to conduct a critical evaluation of the SIS Prenatal in a city of São Paulo State, to compare its data with the local assistance and to verify the registry of pregnant women attended at Health Care Centers. It was analyzed the pregnant women records through consultation at Health Regional Unit and municipal health service. There were inconsistencies between the system and local registry. The failures were related to the inadequate filling of attendance files, besides scarce control of pregnant women files and scheduling on health centers. The results suggest the need for better planning of actions for the improvement of prenatal service quality.

[A quantitative and qualitative study of exclusive breastfeeding intention by high-risk pregnant women]. / Estudo quanti-qualitativo sobre amamentação exclusiva por gestantes de alto risco.

The scope of this research was to assess the breastfeeding intention among high-risk pregnant women and related factors. It is a cross-sectional, qualitative and quantitative study, with 1,118 high-risk pregnant women who attended the prenatal care unit at a specialized center of the Unified Health System. The dependent variables were exclusive breastfeeding intention, intended duration and conditions that might interfere with breastfeeding. The Epi Info 7.4.1, Bioestat 5.3 and IRAMUTEQ 0.7.2.0 programs were used for data processing. The results showed that 8.76% of the pregnant women had conditions that could affect lactation. Among the women, 93.83% affirmed having exclusive breastfeeding intention, of which 69.86% intended to breastfeed until the child was six months old, revealing an association with sociodemographic variables (p<0.05). The intended breastfeeding duration was related to the age (p=0.0041), marital status (p=0.0053) and level of education (p=0.0116). The main reasons reported for not providing exclusive breastfeeding were the following: HIV, use of medications, work and lack of information. This research concluded that a small cohort of high-risk pregnant women presented conditions that could interfere with breastfeeding. Most of them intended to breastfeed exclusively for six months.

Characterization of the self-perception of oral health in the Brazilian adult population.

This article aims to perform an analysis of the factors that determine the self-perception of oral health of Brazilians, based on a multidimensional methodology basis. This is a cross-sectional study with data from a national survey. A household interview was conducted with a sample of 60,202 adults. Self-perception of oral health was considered the outcome variable and sociodemographic characteristics, self-care and oral health condition, use of dental services, general health and work condition as independent variables. The dimensionality reduction test was used and the variables that showed a relationship were submitted to logistic regression. The negative oral health condition was related to difficulty feeding, negative evaluation of the last dental appointment, negative self-perception of general health condition, not flossing, upper dental loss, and reason for the last dental appointment. The use of a multidimensional methodological basis was able to design explanatory models for the self-perception of oral health of Brazilian adults, and these results should be considered in the implementation, evaluation, and qualification of the oral health network.

Health surveillance: public water supply fluoridation in 40 municipalities of São Paulo, Brazil. / Vigilância em saúde: fluoretação das águas de abastecimento público em 40 municípios do estado de São Paulo, Brasil.

Since fluoridation of water is an established public health measure for the prevention of dental caries and considering that monitoring of the method is crucial to its success, this study aimed to analyze the results of the analysis of the fluorine content of public water supply of 40 municipalities in the state of São Paulo, from November 2004 to December 2016. Samples were analyzed monthly using the potentiometric method. Of the 32,488 samples, 50.94% contained fluoride levels within the recommended range. In 2004, it was verified that 21 cities (52.50%) had mean levels within the recommended parameter, increasing to 32 cities (80.00%) in 2016. It was observed that 15 municipalities that initially had levels of fluoride below 0.55 mgF/L in their water supply adjusted to adequate levels during the project. In the first year of the study, 47.76% of the samples had values in the recommended range, which increased to 58.22% in 2016. Most of the municipalities adjusted the levels of fluoride in their waters over the years, evidencing the performance of heterocontrol programs as important strategies that assist in the monitoring of the method and have significant participation in the control of the water quality supplied to the population.

Sendo a fluoretação das águas uma medida de saúde pública consagrada na prevenção de cárie dentária e considerando que a vigilância do método é fundamental para o seu sucesso, este estudo objetivou analisar os resultados das análises dos teores de flúor das águas de abastecimento público de 40 municípios do estado de São Paulo, de novembro de 2004 a dezembro de 2016. A análise das amostras foi realizada mensalmente por meio do método potenciométrico. De 32.488 amostras, 50,94% continham níveis de flúor dentro do intervalo recomendado. Em 2004, verificou-se que 21 cidades (52,50%) apresentaram teores médios dentro do parâmetro recomendado, passando, em 2016, para 32 cidades (80,00%). Observou-se que 15 municípios que possuíam inicialmente níveis de flúor abaixo de 0,55 mgF/L em suas águas de abastecimento adequaram-se no decorrer do projeto. No primeiro ano do estudo, 47,76% das amostras possuíam valores no intervalo preconizado e, em 2016, houve um aumento para 58,22%. Foi verificado que no decorrer dos anos, a maioria dos municípios adequou os níveis de flúor em suas águas, evidenciando a atuação dos programas de heterocontrole como importantes estratégias que auxiliam na vigilância do método, tendo participação fundamental no controle da qualidade da água ofertada à população.

Dental auxiliary hepatitis B immunization: a cross-sectional study in the São Paulo state public health system, Brazil, 2018. / Imunização contra hepatite B em auxiliares em saúde bucal: estudo transversal no sistema público de saúde do estado de São Paulo, em 2018.

OBJECTIVE: to investigate dental auxiliaries (DA) hepatitis B immunization in Brazilian National Health System (SUS) services in nine cities in São Paulo State, Brazil, in 2018. METHODS: this was a cross-sectional study based on interviews using a questionnaire as well as evaluation of immunity using the anti-HBs test, evaluation of prior testing, test result and interpretation and guidance provided about hepatitis B. RESULTS: of the 70 registered DA, 35 completed the course of vaccinations, 29 had negative anti-HBs test results, 16 had tested previously, and 43 did not correctly understand their result; there was association (p=0.025) between completed course of vaccinations and receipt of guidance. CONCLUSION: most DA received guidance about hepatitis B; however, a considerable portion did not complete the course of vaccinations and had negative anti-HBs test results; few DA had tested previously nor correctly interpreted the result; evidence was found of an alarming scenario in which there are severe shortcomings in DA hepatitis B immunization.

Smoking and periodontal disease: clinical evidence for an association.

PURPOSE: The aim of the present study was to assess the periodontal condition and smoking status, according to dose and duration information, and to estimate the percentage of subjects with periodontitis attributable to cigarette smoking in a representative adult rural population in southern Brazil. MATERIALS AND METHODS: Bivariate statistical analysis was used to evaluate the association of smoking status with periodontitis in a cross-sectional study comprising 165 dentate individuals, aged 35 to 66 years, subjected to oral clinical examination of six sites per tooth in all sextants. RESULTS: The prevalence of periodontitis (having > or = 1 pocket of > or = 4 mm around the index teeth) in the population was 35.2%. Overall, 13.9% had a cumulative loss of attachment > 4 mm; 35.7% of subjects were current smokers, classified as heavy (average 25.3 pack years), moderate (average 14.6 pack years) and light smokers (average 3.1 pack years). Statistical analysis showed that current smokers had an 11 times (95% confidence interval [CI] = 4.69 to 26.62) and former smokers had a nine times (95% CI = 3.29 to 25.96) greater probability of having established periodontitis compared with non-smokers. The number of pack years (P = 0.0004) and years of smoking exposure (P = 0.0013) were associated with an increased prevalence of periodontitis. The number of current smokers with periodontitis might be reduced by 80%, had they not smoked cigarettes. Of the subjects with periodontitis, 64% could be prevented among current smokers by eliminating tobacco consumption. CONCLUSIONS: Cigarette smoking was strongly associated with periodontitis, and there was a relationship with dose and duration of smoking. These findings contributed to the evidence of smoking as a risk factor for periodontal disease and support the importance of dose-response analysis on determining the strength of this association.

Fluoride intake from meals served in daycare centres in municipalities with different fluoride concentrations in the water supply.

PURPOSE: The aim of this study was (1) to determine the fluoride content in the meals served to children aged up to 36 months in daycare centres of two municipalities with different levels of fluoride in the water supply, (2) to calculate the mean fluoride ingested daily by the children when consuming those meals and (3) to analyse the contribution of this consumption to the development of dental fluorosis. MATERIALS AND METHODS: Samples of the meals served to the children were collected during a whole week. The fluoride content of the samples of solid foods and milk was analysed using an ion-specific electrode combined with reference electrode after diffusion facilitated by hexamethyldisiloxane. Samples of beverages were buffered with an equal volume of total ionic strength adjustment buffer and analysed using a combined electrode. The results were compared using the Mann-Whitney test. RESULTS: Mean fluoride contents of the meals were of 0.204 +/- 0.179 and 0.322 +/- 0.242 microg F/mL (P < 0.05), respectively, in the municipalities with low and adequate fluoride content. Daily fluoride intake in the former was 0.013 +/- 0.003 mg/kg body weight/day and in the latter was 0.012 +/- 0.001 mg/kg body weight/day (P > 0.05). CONCLUSIONS: The children were not exposed to dental fluorosis in the daycare centres. However, the risk cannot be ignored, considering the meals and the use of fluoridated dentifrices at home may also contribute to fluoride intake.

Dentistry in Brazil: its history and current trends.

The objectives of this article are to provide a short history of dentistry and dental education in Brazil and to analyze the nature of its development to date. The databases consulted are those provided by the Brazilian Federal Council of Dentistry, Brazilian Ministry of Health, Brazilian Ministry of Education, National Institute of Studies and Educational Research Anísio Teixeira, and Brazilian Institute of Geography and Statistics. Formal dental education in Brazil started in the late nineteenth century with the creation of courses annexed to existing schools of medicine in Rio de Janeiro and Bahia. Today, there are 191 institutions of higher education nationwide granting degrees in dentistry (137 private [71.7 percent] and fifty-four public [28.3 percent]), with a total of 17,157 student positions offered annually. These schools graduate around 10,000 professionals per year-one of the highest rates in the world. Both the distribution of schools of dentistry and of dentists varies among the regions of the country, with the greatest concentrations in major metropolitan centers with high population density, resulting in limited coverage in the more deprived regions. A review of epidemiological data for oral health and distribution of dentists in Brazil indicates that there is a lack of systematic planning for the allocation of the dental workforce and a lack of consideration of regional needs in the development of dental training programs in Brazil today.

Caries Experience in Preschool Children over a 10-year Period.

PURPOSE: To analyse the caries experience in preschool children at two moments 10 years apart. MATERIALS AND METHODS: Two cross-sectional epidemiological studies, the first in 2006 (n = 275) and the second in 2016 (n = 258), were carried out with samples composed of children from 3 to 6 years of age. All children were enrolled in the municipal schools of basic education of a municipality in northwest São Paulo state, and they attended an annual and continuous oral health education programme. Caries experience was calculated for deciduous and permanent teeth using the dmft and DMFT indices, according to the World Health Organization (WHO). Statistical analysis was performed using Epi info 7.1 and Bioestat 5.0 software. RESULTS: In 2006, the mean dmft index was 1.88, with 7.59% of teeth having caries experience. In 2016, the mean dmft index was 0.99, with 5.15% of teeth showing caries experience. In contrast, in 2006, the mean DMFT index was 0.08 (n = 509), with 4.1% of teeth with caries experience; in 2016, the mean DMFT index was 0.06 (n = 381) and 3.6% of teeth showed caries experience. The proportions of teeth with caries experience differed statistically significantly (p = 0.435). In the last study, 78.2% of the children were caries free, below the WHO target for 2020. The Significant Caries Index (SiC Index) was 0.2. CONCLUSION: A decline of caries experience in the deciduous dentition was found in the study population.

Clinical and Microbiological Analysis of Mechanical and Chemomechanical Methods of Caries Removal in Deciduous Teeth.

PURPOSE: This study evaluated carious tissue removal by mechanical and chemomechanical methods (Carisolv and Papacárie) through colony-forming unit (CFU) counts of Streptococcus mutans and Lactobacillus sp. Treatment acceptability, presence and level of pain, use of anesthesia, time required for caries removal and pain 24 h after treatment were also compared. MATERIALS AND METHODS: A clinical trial with 32 individuals who had at least two deciduous molars with active occlusal caries lesions were selected and randomly divided into two groups (I and II). One lesion in each individual was excavated with hand excavator only. The remaining lesions were excavated using modified hand excavation and Carisolv in group 1 or modified hand-excavation and Papacárie in group 2. Bacterial samples were taken from each caries lesion before and after treatment. RESULTS: All the methods reduced the amount of cultivable Streptococcus mutans and Lactobacillus sp. after treatment (p < 0.05) and no statistically significant difference was found between the groups (p > 0.05). There was 97% acceptability of treatments, and anesthesia was used in 14% of teeth. Pain was present 24 h after treatment in 6% of teeth. The mean times for caries removal by the mechanical and chemomechanical treatments were not statistically significantly different (p > 0.05). CONCLUSIONS: All treatments were found to effectively reduce bacterial counts (p < 0.05). There were no statistically significant differences (p > 0.05) among treatments or between clinical variables (p > 0.05).

Vaccination coverage and immunity against hepatitis B in public health dentists.

INTRODUCTION: Occupational exposure is a major risk factor for hepatitis B (HB) transmission. METHODS: Vaccination coverage and immunity verification from 64 dentists of the Brazilian Unified Health System were investigated. An immunochromatographic method was used to verify immunity against the disease. RESULTS: Overall, 77.77% of participating dentists completed the vaccination schedule; 37.50% had negative anti-HBs test results. Furthermore, 60.93% of participants never underwent anti-HBs tests and 40% did not know how to correctly interpret results. CONCLUSIONS: Numerous dentists were not immune to the disease. Few participants previously performed the test, with many not knowing how to interpret the results.
