RESUMO

Abstract Brazil's public healthcare system (SUS) offers specialized oral health services to Brazilians, but the productivity of specialists, such as Pediatric Dentists, has not been characterized. Therefore, the objective of this study was to characterize the outpatient dental procedures (ODPs) carried out by Pediatric Dentists within the SUS. An epidemiological study with an ecological, longitudinal, retrospective, and quantitative approach was conducted. The ODPs carried out by Pediatric Dentists within the SUS were characterized based on type of procedure, complexity level, and circumstance (urgent or elective). Data were analyzed using a descriptive and analytical approach, considering a significance level of 5%, as well as the impact of the COVID-19 pandemic (the 2020-2022 years were not included in secondary analyses). In the last 15 years, 29,234,972 ODPs were carried out by Pediatric Dentists within the SUS. Clinical procedures were the majority (55.4%), significantly more frequent than all other types of procedures (all p <0.05). Among these, restorative and periodontal procedures were the most common (30.7% and 21.0%, respectively). From 2008 to 2019, excluding COVID-19 pandemic years, the trend over the last 15 years was constant for all types of procedures (all p >0.05). In addition, low complexity ODPs were the majority (90.1%), significantly more frequent than medium (9.7%) and high complexity procedures (0.1%) (both p <0.05). At last, most ODPs were not characterized by circumstance in the outpatient production reports (96.9%). Therefore, it was possible to conclude that Pediatric Dentists carried out diverse ODPs within the SUS over the past 15 years, although there was a dominant pattern of type and complexity.

RESUMO

ABSTRACT Objective: To determine the prevalence and risk factors associated with dental caries in Brazilian preschool children aged 2 to 5 years. Material and Methods: The following independent variables were evaluated: dental caries, dental trauma, and malocclusions. Data were analyzed using the Mann-Whitney test and Poisson regression (p<0.05). Results: The prevalence of dental caries in preschoolers was 55.1%. Child age, family income, maternal education, and tooth color alteration from trauma were significantly associated with dental caries (p<0.05). The final adjusted multivariate model showed a significant association between maternal education and dental caries; children of mothers with low education were 1.89 times more likely to have caries (PR: 1.89; 95%CI: 1.40-2.55) (p<0.01). Children with tooth color change from trauma were more likely to have dental caries (PR: 1.69; 95%CI: 1.22-2.34 (p=0.001). Conclusion: Child age, family income, maternal education, tooth discoloration and discoloration color are risk factors for the development of caries disease in children. Also, children of mothers with low educational levels have a higher chance of developing dental caries.

RESUMO

OBJECTIVES: To systematically evaluate randomized controlled trials (RCTs) on whether a chewable toothbrush (CTB) is more effective than a manual toothbrush (MTB) in terms of full-mouth dental plaque reduction in non-orthodontic children. MATERIALS AND METHODS: Six databases were searched by two independent reviewers according to pre-specified eligibility criteria up to October 2022. No restrictions regarding language, date of publication and minimum follow-up period were imposed. The Cochrane Collaboration's Risk of Bias tool (RoB 2.0) was used for quality appraisal and GRADE for assessing the certainty of evidence. Random-effects pairwise meta-analysis compared the dental plaque change scores of CTB and MTB through mean differences (MDs) and associated confidence intervals (95% CI), and sensitivity analysis determined whether an individual study significantly affected the results. RESULTS: Seven eligible RCTs were retrieved, including data of 310 children aged 8-14 years. Five RCTs present some concerns and two have high RoB. No significant difference was detected between toothbrushes in terms of Turesky modification of the Quigley-Hein plaque index reduction (MD = -0.04, 95% CI: -0.26-0.18), with overall very low certainty on evidence. The pooled estimate remains unchanged when any RCT is omitted. CONCLUSION: There is very low-certainty evidence of no significant difference on plaque removal between MTB and CTB in non-orthodontic children. Due to unexplained high heterogeneity and low methodological quality of RCTs, we cannot determine the extent to which our finding reflects a true effect or bias arising from limitations of primary studies.

RESUMO

OBJECTIVE: to investigate the impact of the severity of microcephaly caused by the Zika virus (MCZ) on tooth eruption and orofacial structures of children. DESIGN: This case series study developed the research at the Mens Sana Rehabilitation Center, Arcoverde, Brazil. The study included 27 children diagnosed with MCZ. We performed the data collection in June 2018 through a questionnaire answered by the legal guardians, followed by a clinical examination of the children. The data were analyzed by the Mann-Whitney and Fisher's exact tests (p = 0.05). RESULTS: The final sample was composed of 20 children. Of these, 13 (35.0%) had severe microcephaly, 5 (30.0%) had altered sequence of tooth eruption, 10 (50.0%) had delayed eruption, and the mean number of decayed teeth was 2.3. The most identified orofacial changes were teeth grinding habit (65.0%), difficult chewing (50.0%), and non-nutritive sucking (50.0%). The Mann-Whitney test showed that the severity of microcephaly did not affect tooth eruption (p = 0.581). The Fisher's exact test showed that the severity of microcephaly was not associated with orofacial changes (p > 0.05). CONCLUSIONS: The severity of MCZ does not seem to influence changes in deciduous tooth eruption and the presence of orofacial anomalies.

RESUMO

ABSTRACT Objective: To evaluate the behaviour and stress of children undergoing restorative treatment with and without sedation. Material and Methods: Participants were 14 healthy children aged between 2.5 and 6 years and with a history of dental behavioural management problems. In the dental treatment visit, the child was treated with non-pharmacological techniques, and in the second, moderate sedation was added. The child received the same procedure performed by a paediatric dentist in both visits: composite resin restoration using local anaesthesia and rubber dam isolation. In both visits, saliva was collected at the children's arrival at the dental clinic, during local anaesthesia and at the end of treatment. The visits were filmed for later analysis of behaviour according to the Ohio State University Behavioural Rating Scale. Results: About 78.5% of children improved their behaviour from the first to the second visit. The salivary cortisol curve of the first visit was maintained in the second visit for 21.4% of children but varied in the remaining participants. Conclusion: Most children presented better behaviour and less stress when sedation was added to non-pharmacological techniques during dental care.

RESUMO

Abstract: Parental behavior towards their children's oral health is strongly influenced by parent's Oral Health Literacy (OHL) level. This study evaluated the impact of parental OHL on preschool children's utilization of dental services. A cross-sectional study was conducted with parents of 419 children aged 3 to 5 years who answered a self-administered questionnaire about their perception of their children's oral health and whether their children had already been to a dental visit. Parental OHL level was assessed by the validated version of the Oral Health Literacy Adult Questionnaire (OHL-AQ) translated into Brazilian Portuguese. Univariate and multivariate Poisson regression analyses with robust variance were used for the data analysis (α = 0.05). Most children had already been to a dental visit (73%). Overall, 31.7% of the parents or guardians reported that their children had experienced dental pain or dental caries. Parental OHL level was classified by tercile as low, medium, and high. The final model showed independent associations between children who had already been to a dental visit and higher parental OHL level (PR = 1.16; 95%CI = 1.00-1.35) when compared to the lowest OHL level, higher parental educational level (PR = 1.39; 95%CI = 1.03-1.87) when compared to lower educational level, the report of children's pain and dental caries (PR = 1.22; 95%CI = 1.09-1.36) and married parents or parents in a common-law marriage (PR = 1.17; 95%CI = 1.03-1.93). The prevalence of children who had already been to a dental visit was higher among those parents with a higher OHL level when compared to those with a lower OHL level.

RESUMO

BACKGROUND: Due to the high transmissibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), governments adopted preventive measures, such as social distancing and obligatory social immobilization, which negatively affected access to health services, including oral health services. Similarly, dental care restraint arose in this context, with the aim of reducing the possibility of cross-infection caused by aerosols, which notably restricted dental care activity. OBJECTIVES: The aim of the study was to determine the impact of the COVID-19 pandemic on the timing of dental care in Peruvian children. MATERIAL AND METHODS: A cross-sectional study with a population of 42,115 respondents for 2019 and 20,510 for 2020 was conducted. The participants were children aged 0-11 years. The records of those who responded to the question on the time since their last dental care were considered, extracting a total of 22,166 (69.03%) subjects for 2019 and 9,945 (30.97%) subjects for 2020. The dependent variable consisted of the time since the last dental care measured in years; the variables of health, geographic and sociodemographic characteristics were grouped within 3 dimensions. Descriptive bivariate and multivariate analyses were applied by means of multiple linear regression in order to analyze the variables. RESULTS: The time since the last dental care during 2019 was 5.25 ±4.30 years, and it increased to 6.64 ±4.90 years in 2020. Within the multivariate analysis, the dimensions and their variables were ordered hierarchically for 2019 and 2020 separately, and as a whole. Each model was not significant when observed independently (p > 0.05); however, when evaluated as a whole, validity was observed only in model 1 of the year (p = 0.018), with R2 = 2.90, a constant equal to 3.852, the non-standardized regression coefficient (ß) of 1.653, and a 95% confidence interval (CI) of 0.289-3.018. CONCLUSIONS: The 2020 COVID-19 pandemic year had a negative impact on the timing of dental care in Peruvian children, increasing it by 1.39 years as compared to 2019.

RESUMO

AIMS: This study aimed to report the perception of parents of children/adolescents with autism regarding the parents' fear of the pandemic by COVID-19. Also, to report children's fear about the use of individual protective equipment (IPE) in dental appointments, and the impact on the daily routine during the pandemic. METHODS AND RESULTS: A cross-sectional study through an open online survey was addressed to parents of children/adolescents autistic, aged between 3 and 18 years. The questionnaire had questions regarding the parents' fear of the COVID-19 pandemic, the parents' perception about the children/adolescents' fear of the use of IPEs at dental care, and the impact of the daily routine during the pandemic and social impact after the pandemic. Parents' reports on the degree of ASD (mild, moderate, and severe) of the child/adolescent. A total of 1001 responses were obtained. 50.35% of parents had high fear of the pandemic by COVID-19, 59.34% believe that children/teenagers will be afraid of the dentist's IPE and 61.64% responded that the COVID-19 pandemic had a high impact on the daily routine of children/adolescents with ASD. CONCLUSIONS: Most parents reported fear of the pandemic by COVID-19, that children/adolescents with autism may be afraid of IPE and had a high impact on their daily routine during the pandemic.

RESUMO

Abstract Objective: To analyze the differences in early childhood caries status on parental stress levels and socioeconomic status in Makassar City, Indonesia, during the COVID-19 pandemic. Material and Methods: This type of analytical observational study with a cross-sectional design was conducted in North Rantepao, Toraja City, South Sulawesi Province, Indonesia. The research subjects of this study were parents who met the criteria, were willing to participate in the study, and had children aged 6-17 years. The questionnaire instrument with the criteria for assessing children's dental and oral health was assessed based on parents' perceptions. Each item is rated on a scale from 1 (never) to 5 (always). Then the total score was divided into three categories, namely low (score 3-6), moderate (score 7-10), and high (score 11-15). Comparative test analysis using Chi-Square test. Results: Parents with high-stress levels had more children with poor oral health. There is a significant difference according to the level of stress and socioeconomic status of the parents. Conclusion: There is a significant difference between caries status in early childhood based on socioeconomic status and parental stress level (AU).

RESUMO

Abstract: There is a lack of evidence on the correlation between salivary biomarkers and subjective measures of dental fear and anxiety in children. This systematic review aimed to retrieve the scientific evidence comparing the results of dental anxiety measured by salivary biomarkers with patient-reported outcomes in pediatric dental setting. The PECOS was as follows: population: pediatric patients aged ≤ 18 years; exposure: patient-reported outcome measures, such as scales and/or questionnaires; comparator: salivary biomarkers; outcome: anxiety, fear, phobia or stress during dental treatment; study design: observational studies or controlled trials. Electronic searches were conducted in PubMed, Scopus, Web of Science, and Ovid databases. Studies that compared scales/questionnaires and salivary biomarkers for the evaluation of dental anxiety, fear, and stress in children/adolescents during dental treatment were included. Certainty of evidence was assessed with GRADE. Risk of bias of the included studies was assessed with the Cochrane tool or the University of Adelaide tool. From the 314 studies identified, eight were included. Participants' age ranged from three to 13 years. The most used salivary biomarkers and instruments were cortisol and the Dental Subscale of the Children's Fear Survey Schedule, respectively. Most studies showed a weak correlation between objective and subjective measures. The main issues regarding bias were on allocation concealment, blinding of assessors, follow up, and exposure assessment. Certainty of evidence was low/very low. Evidence of salivary biomarkers and patient-reported outcome measures to investigate anxiety, fear and stress in children during in the dental environment is limited. There was no correlation between subjective and objective measures in almost all included studies.

RESUMO

RESUMEN Introducción: la mayoría de la población acepta como inevitable la pérdida de los dientes con la edad, pero si estuviera mejor informada y adoptara actitudes y prácticas favorables con relación a su salud bucal, la prevalencia y gravedad de estas afecciones se reduciría considerablemente; esto motiva a buscar soluciones a través de políticas de salud que implementen planes especialmente diseñados a tal efecto. Objetivos: identificar el nivel de información sobre salud bucodental, diseñar y aplicar acciones educativas en escolares de preescolar a tercer grado de la Escuela «René Fraga». Métodos: se realizó una investigación, con metodología cualitativa y cuantitativa, en el período comprendido entre marzo 2017 a mayo 2018. Se utilizaron varios métodos e instrumentos para la obtención de la información entre los que se destacan: la observación y la entrevista. La muestra estuvo conformada por 248 infantes, y fue seleccionada por criterios. La información se obtuvo a través de: la observación, la aplicación de una entrevista para explorar información sobre salud bucal en los niños y niñas, todo esto con previo consentimiento informado de instituciones y padres. Resultados: los resultados obtenidos señalan entre otros aspectos: dificultades en la forma, frecuencia y orientación del cepillado, así como el nivel de información sobre salud bucodental; se diseñaron y aplicaron acciones en correspondencia con las necesidades educativas identificadas. Conclusiones: las niñas y niños mostraron un nivel de información sobre salud bucodental no adecuado durante el diagnóstico; este mejoró considerablemente después de aplicadas las acciones educativas diseñadas.

ABSTRACT Introduction: the majority of the population accepts tooth loss as inevitable as they age, but if they were better informed and adopted favourable attitudes and practices regarding their oral health, the prevalence and severity of these conditions would be considerably reduced; this motivates us to look for solutions through health policies that implement plans specially designed for this purpose. Objectives: identifying the level of information on oral health, as well as designing and applying educational actions in schoolchildren from preschool age to third grade belonging to "René Fraga" School. Methods: a qualitative and quantitative research was carried out from March 2017 to May 2018. Several methods and instruments were used to obtain information, among which observation and interview stand out. The sample consisted of 248 infants, and was selected by criteria. The information was obtained through observation and the application of an interview to explore information on oral health in children; all this with the prior informed consent of institutions and parents. Results: the obtained results indicate, among other aspects: difficulties in shape, frequency and orientation of brushing, as well as in the level of information on oral health; actions were designed and applied in correspondence with the educational needs identified. Conclusions: girls and boys showed an inadequate level of information on oral health during the diagnosis; this improved considerably after applying the designed educational actions.

RESUMO

Outpatient pediatric sedation is challenging. This study aimed to test intranasal dexmedetomidine efficacy as a single drug or combined with ketamine (DK) to sedate children undergoing dental treatment. Children < 7 years were randomized into dexmedetomidine 2 mcg/kg and ketamine 1 mg/kg (DK) or dexmedetomidine 2.5 mcg/kg (D) groups. Videos from the dental sedation allowed the systematic assessment of children's behavior (primary outcome) according to the Ohio State University Behavioral Rating Scale (OSUBRS). Secondary outcomes were parental and dentist satisfaction, adverse events, and recovery time. The data were analyzed descriptively and through regression models. Participants were 88 children (44 per group; 50 boys). The duration of quiet behavior (OSUBRS) was higher than 50% (DK mean 58.4 [standard deviation 38.1]; D 55.2 [39.1]; p = 0.225). Parents (DK 78.0 [32.2]; D 72.7 [35.1]; p = 0.203) and dentists (KD 62.7 [41.0]; D 62.8 [40.1]; p = 0.339) were overall satisfied. Adverse events occurred in 16 cases (DK n = 10, 62.5%; D n= 6, 37.5%; p = 0.104) and were minor. The median recovery time in the DK group was 1.3 times greater than in group D (p < 0.05). Intranasal sedation with dexmedetomidine alone is equally efficacious and satisfactory for pediatric sedation with fewer adverse events and faster recovery than the DK combination.

RESUMO

BACKGROUND: There is a lack of evidence on the effectiveness of moderate sedation in pediatric dentistry, compared to protective stabilization, which remains routinely used in Brazil despite moral questions. This prospective non-randomized clinical trial's objective is to evaluate the effectiveness of moderate sedation, compared to the protective stabilization, in the dental care of children with dental behavior management problems. METHODS: Participants will be 152 children under seven years of age with early childhood caries (ECC) who need specialized dental treatment due to a history of challenging behavior during dental care. The interventions to be compared are moderate sedation with oral administration of ketamine and midazolam and protective stabilization. The primary endpoint will be the child's behavior during treatment assessed using the Ohio State University Behavioral Rating Scale (OSUBRS). The secondary outcomes are (A) child's - behavior according to the visual analogue scale, anxiety, pain, and physiological stress; (B) parent's - satisfaction and anxiety; (C) family and child - impact on oral health-related quality of life (OHRQoL); (D) dentist's - satisfaction and stress; (E) procedure - adverse events of the intervention and dental treatment longevity. A cost-effectiveness analysis will be performed from the perspective of the Brazilian Unified Health System (SUS). DISCUSSION: Considering the primary outcome, this study hypothesis is that sedated children have better behavior during dental treatment than children whose behavior was managed by protective stabilization without sedation. Additionally, at the end of 12 months, we expect to identify participants' reported outcomes and objective measures related to dental behavior in early childhood.

RESUMO

BACKGROUND: The presence of parents during the dental appointment can affect the child's behaviour and, consequently, the success of the treatment. AIM: This systematic review aimed to evaluate whether parents' presence in the operatory room influences children's behaviour, anxiety and fear during dental treatment. DESIGN: EMBASE, Cochrane Library, LILACS, PubMed, PsycINFO, Scopus, Web of Science, Google Scholar, OpenGrey and ProQuest Dissertations and Theses Databases were searched. Randomized and non-randomized clinical trials in which some measure assessing children's behaviour and/or anxiety and fear during dental treatment with the presence and absence of parents were included. Two reviewers assessed studies for selection, extracted data, evaluated bias (Joanna Briggs Institute) and graded the certainty of evidence (Grading of Recommendations, Assessment, Development and Evaluation). Random-effects meta-analyses using mean difference (MD) and narrative synthesis were performed. RESULTS: A total of 2846 papers were identified, and after a 2-phase selection, sixteen studies were included (five in meta-analyses). There was no difference in children's behaviour in the presence or absence of parents (P = .23, P = .40, P = .60 and P = .89, respectively). The presence or absence of parents did not influence children's anxiety (P = .94 and P = .97) or fear (DM: -0.08; CI:-0.34-0.19, P = .24). All included studies presented a high risk of bias, and the certainty of evidence was considered to be very low. CONCLUSION: It is concluded that parents' presence in the operation room does not influence children's (up to 12 years old) behaviour, anxiety and fear during dental treatment with very low certainty of evidence. Methodological limitations of included studies, however, suggest that better designed trials are needed to adequately understand this issue.

RESUMO

ABSTRACT Objective: To determine the children's primary dental treatment needs reported by the parents and pediatric dentists. Material and Methods: 125 children (36 girls and 89 boys) and their parents participated in this study. The children's decayed-missing-filled teeth/teeth surfaces scores were recorded. A questionnaire about their children's primary dental treatment needs was conducted with the parents. Shapiro-Wilk test was used to test the normality of the data. Kruskal-Wallis test was used to compare the clinical findings according to the categorical variables. The Chi-Square test was used to compare the categorical data. Also, multiple linear regression analysis was performed to determine the effect of some variables on children's dmft/DMFT scores. The significance level was accepted as p<0.05. Results: The average age of the children who participated in the study was 7.59 ± 2.36 years. The main reason for applying to the paedodontics clinic was dental caries (38.4%), followed by dental pain (33.6%). As for the primary dental treatment needs, 28% of the parents said they needed dental filling, while 19.2% said they needed orthodontic treatment. According to the pediatric dentists, while the treatment rate of dental caries was 47.2% as the primary treatment need, it was only 4.8% for the orthodontic treatments. Conclusion: Turkish children who were admitted to paedodontics clinics were too old and dental caries and dental pain were the most common reasons for these visits to the clinics. The children's needs for primary treatment varied according to parents and pediatric dentists. There is a need for more comprehensive studies about the subject.

RESUMO

O objetivo dessa pesquisa foi analisar o perfil da manifestação de lesões de cárie em pacientes de 0 a 10 anos de idade atendidos em um Programa Odontológico Educativo Preventivo (POEP). Neste projeto as crianças foram atendidas dos 0 aos 5 anos de idade na Bebê-Clínica (BC) e dos 5 aos 10 anos na Clínica de Prevenção (CP). Foram analisados 754 prontuários e destes, selecionados 381, cujas crianças apresentaram lesão de cárie dentária. Dados como sexo, dente acometido, tipo de lesão, tratamento realizado e data da ocorrência foram registrados em planilha do Microsoft Excel 2010. Análises estatísticas descritivas e inferenciais foram realizadas pelo programa Sigma Plot 12.0. Foram utilizados os testes Qui-Quadrado e de Mann-Whitney, ambos com nível de significância de 5%. Dos prontuários selecionados, 178 (47%) eram de crianças do sexo masculino e 203 (53%) do sexo feminino. Um total de 1375 lesões foram registradas e o grupo de dentes mais acometido foi o de molares decíduos inferiores (31,4%). O dente 55 foi o mais frequente (10,1%) e a superfície oclusal, a mais envolvida (41%). Na BC o grupo de dentes mais acometido foi o de molares inferiores (37%), sendo os dentes 75 e 51 os mais frequentes, ambos com 9,7%, e a superfície vestibular, a mais afetada, com um total de 172 (45%) ocorrências. Na CP prevaleceram os molares decíduos superiores com 33% do total, sendo o dente 55 o mais afetado (11,8%) e a face oclusal, a mais acometida, com 447 (45%) ocorrências. Em relação ao tipo de lesão, tanto na BC quanto na CP prevaleceu a cárie cavitada em esmalte com 47% e 71%, respectivamente. O tipo de tratamento mais realizado foi o tratamento restaurador na BC (50,6%) e na CP (90,5%). Conclui-se durante o POEP que a lesão de cárie ocorreu com maior frequência em dentes posteriores, sendo o dente 55 o mais afetado (10,1%) e a superfície oclusal a mais acometida (41%). Entretanto, considerando separadamente as fases BC e CP, os resultados diferiram para o dente e superfície mais afetados(AU)

The aim of this research was to analyze the profile of the manifestation of caries lesions in patients aged 0 to 10 years old treated in a Preventive Dental Education Program (POEP). In this project, children were assisted from 0 to 5 years of age at the Baby-Clinic (BC) and from 5 to 10 years at the Prevention Clinic (CP). A total of 754 medical records were analyzed, and of these, 381 were selected, whose children had dental caries lesions. Data such as sex, affected tooth, type of injury, treatment performed and date of occurrence were recorded in a Microsoft Excel 2010 spreadsheet. Descriptive and inferential statistical analyzes were performed using the Sigma Plot 12.0 program. The Chi-Square and Mann-Whitney tests were used, both with a significance level of 5%. Of the selected records, 178 (47%) were from male children and 203 (53%) were female. A total of 1375 injuries were recorded and the group of teeth most affected was the lower primary molars (31.4%). Tooth 55 was the most frequent (10.1%) and the occlusal surface was the most involved (41%). In BC, the group of teeth most affected was the lower molars (37%), with teeth 75 and 51 being the most frequent, both with 9.7%, and the buccal surface, the most affected, with a total of 172 (45%) occurrences. In PC, the upper primary molars prevailed with 33% of the total, with tooth 55 being the most affected (11.8%) and the occlusal surface being the most affected, with 447 (45%) occurrences. Regarding the type of lesion, both in BC and PC, cavitated enamel caries prevailed with 47% and 71%, respectively. The most common type of treatment was restorative treatment in BC (50.6%) and CP (90.5%). It was concluded during the POEP that dental caries lesions occurred more frequently in posterior teeth, with tooth 55 being the most affected (10.1%) and the occlusal surface being the most affected (41%). However, considering BC and CP phases separately, the results differed for the most affected tooth and surfasse(AU)

RESUMO

ABSTRACT Objective: To evaluate the role of poverty and its related factors on early childhood caries (ECC) experience among deprived children. Material and Methods: This population-based cross-sectional study surveyed 418 children aged one to six years enrolled in Brazilian public preschools from an area of the country known for its high social deprivation. Intraoral examination of children evaluated dental caries experience (dmft). Parents/caregivers answered a questionnaire with sociodemographic indicators. Family income was dichotomized into below or above poverty line. Data analysis used Chi-square test, Mann-Whitney test, and Multivariate Logistic Regression analysis (p<0.05). Results: Predisposing variables for an increased chance of ECC were: age group 3-4 years (OR: 4.89; 95% CI: 2.32-10.31), age group 5-6-years (OR: 5.60; 95% CI: 2.60-12.04), being part of families living below poverty line (OR: 1.88; 95% CI: 1.04-3.38) and having mothers with less than nine years of schooling (OR: 2.86; 95% CI: 2.77-7.14). Children from families living below poverty line presented higher dmft (2.9 +3.8; p=0.001) and untreated dental caries (d component) (2.7 +3.7; p=0.002). Conclusion: ECC in a poor population was influenced by indicators of social deprivation. The poorest of poor children from mothers with less years of schooling were at higher risk.

RESUMO

INTRODUCTION: The adoption of adequate oral hygiene practices is important for the maintenance of good oral health in children. Rural-urban differences in the achievement of this important issue in Peru remain unknown. The objective of this study was to assess rural-urban differences in the proportion of adequate oral hygiene practices in Peruvian children aged less than 12 years, as well as associated sociodemographic factors. METHODS: This was a cross-sectional study of the 2018 Peruvian Demographic and Family Health Survey. Data from 41 330 children aged 1-11 years and their caregivers with complete information on oral hygiene practices were included in the study. Crude and adjusted prevalence ratios and 95% confidence intervals were estimated as measures of association between adequate oral hygiene practices (defined as toothbrushing two or more times a day, having a toothbrush for individual use and changing toothbrushes every 3 months) and sociodemographic variables. RESULTS: The prevalence of adequate oral hygiene practices was 38.3% in the rural area and 57.3% in urban areas. The greatest rural-urban disparities for adequate oral hygiene practices were observed in the age group of 6-11 years (43.4% v 64.1%), those in families in which the head of the household had no formal education (28.1% v 47.3%) or primary education (36.8% v 53.0%), those who had used dental services in the previous 6 months (46.4% v 64.4%) and those residing in the highlands (31.5% v 48.2%). All independent variables were significantly associated with adequate oral hygiene practices in rural areas, except for the jungle region variable and the richest wealth index. CONCLUSION: Four out of ten Peruvian children living in rural areas perform adequate oral hygiene practices compared to six out of ten children in urban areas. Furthermore, inequalities in the adoption of oral hygiene practices favor urban children according to sociodemographic factors. Strengthening of oral health promotion strategies is urgently needed in order to decrease inequalities in the adoption of adequate oral hygiene in children living in rural areas of Peru and countries with similar sociodemographic characteristics.
