Adolescent pregnancy in Cruzeiro do Sul, Acre, Brazil: socioeconomic characteristics, prenatal and obstetric care. / Parturientes adolescentes em Cruzeiro do Sul, Acre, Brasil: características socioeconômicas e obstétricas.

The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil.

Trata-se de uma análise de dados da linha de base da coorte de nascimentos MINA-Brasil conduzida no município de Cruzeiro do Sul, estado do Acre. Utilizou-se teste qui-quadrado para comparar características das puérperas adolescentes com as adultas e modelos múltiplos de regressão de Poisson com variância robusta para avaliar fatores associados. Entre as puérperas estudadas, 26,2% (IC95%: 24,0-28,4) eram adolescentes. Os fatores associados ao parto na adolescência foram ter nove anos ou menos de estudo (RPaj:1,36; IC95%: 1,14-1,61), pertencer aos menores quartis do índice de riqueza (1° quartil: RPaj:1,40; IC95%: 1,08-1,80) (2° quartil: RPaj:1,37; IC95%: 1,08-1,74), ser primigesta (RPaj:3,69; IC95%: 2,98-4,57), baixo IMC pré-gestacional (RPaj:1,28; IC95%: 1,04-1,57), infecção urinária na gravidez (RPaj:1,25; IC95%: 1,07-1,46) e menos de seis consultas de pré-natal (RPaj:1,42; IC95%: 1,21-1,66). Pobreza, baixa escolaridade, primigestação, baixo IMC pré-gestacional, infecção urinária na gestação e menor número de consultas de pré-natal foram associados ao parto na adolescência em município da região Norte do Brasil.

Impact of pulpectomy versus tooth extraction in children's oral health-related quality of life: A randomized clinical trial.

AIM: The aim of this randomized clinical trial was to compare the impact of two management options for primary molars with pulp necrosis (pulpectomy or extraction) on children's oral health-related quality of life (OHRQoL). DESIGN: A total of 100 children aged 3-5 years with at least one necrotic primary molar were selected and randomized into the study groups. The Brazilian version of early childhood oral health impact scale (B-ECOHIS) was completed by the parent proxy reports at baseline and after 4, 8 and 12 months. Differences between the trial groups were assessed through bootstrap linear regression for B-ECOHIS scores, logistic regression for dental pain self-reports and anxiety scores (α = 5%). RESULTS: The mean (SD) B-ECOHIS scores at baseline and after 12 months were 17.7 (6.5) and 3.0 (4.0) in the pulpectomy group and 18.8 (7.7) and 7.9 (7.7) in the extraction group. Both treatments significantly improved OHRQoL, but tooth extraction group showed higher scores in total B-ECOHIS (p < .001) and most domains, indicating lower OHRQoL. Furthermore, higher anxiety levels were reported for dental extraction compared to pulpectomy (OR = 2.52; p = .008). CONCLUSION: Pulpectomy resulted in an improved OHRQoL scores after 12 months when compared to tooth extraction and should be considered as the treatment of choice for necrotic primary molars.

Dental Caries, Tooth Loss and Quality of Life of Individuals Exposed to Social Risk Factors in Northeast Brazil.

This study aimed to investigate the impact of dental caries and tooth loss on oral health-related quality of life (OHRQoL) in socioeconomically disadvantaged people. A population-based, cross-sectional survey was conducted in 28 cities at social risk in Northeast Brazil. All permanent residents aged 12, 15-19, 35-44, and 65-74 years were eligible, and 3063 were included. Participants answered a questionnaire on socioeconomic status, beliefs, and behaviors. Trained local dentists performed oral clinical examinations during home visits. Caries and tooth loss were evaluated using the decayed, missing, and filled teeth (DMFT) index and OHRQoL was evaluated using the Oral Health Impact Profile-14 (OHIP-14). Poisson regression analysis was performed to assess the relationship between individual domains, OHIP-14 scores, dental caries, tooth loss, and socioeconomic/demographic characteristics. Mean DMFT (standard deviation) scores were 2.68 (4.01), 4.84 (4.30), 15.35 (7.26), and 26.72 (8.03) for groups aged 12, 15-19, 35-44, and 65-74 years, respectively. Most participants (70%) were partially edentulous and 13% were completely edentulous. Caries and tooth loss significantly increased with age and impacted OHRQoL. Physical pain (5.8%) and psychological discomfort (5.8%) were the most commonly reported on the OHIP-14. Untreated caries (prevalence ratio (PR), 1.54; 95% confidence interval (CI), 1.37-1.72) and edentulism (PR, 1.29; 95% CI, 1.08-1.53) had a significant negative impact on OHRQoL. Income, level of education, sex, age, and oral hygiene habits were also related to OHRQoL. There was a high prevalence of dental caries and edentulism in all age groups except 12-year-olds. OHRQoL was negatively impacted by these oral conditions across the lifespan, with a trend towards more negative scores and higher impact in older adults.

Prolonged breastfeeding, sugar consumption and dental caries at 2 years of age: A birth cohort study.

OBJECTIVES: Previous cohort studies have found a positive association between prolonged breastfeeding (≥12 months) on dental caries, but few of them analysed the mediated effect of sugar consumption on this association. This study investigated whether prolonged breastfeeding is a risk factor for caries at 2-year follow-up assessment (21-27 months of age) and whether this effect is mediated by sugar consumption. METHODS: A birth cohort study was performed in the Brazilian Amazon (n = 800). Dental caries was assessed using the dmf-t index. Prolonged breastfeeding was the main exposure. Data on baseline covariables and sugar consumption at follow-up visits were analysed. We estimated the OR for total causal effect (TCE) and natural indirect effect (NIE) of prolonged breastfeeding on dental caries using the G-formula. RESULTS: The prevalence of caries was 22.8% (95% CI: 19.8%-25.8%). Children who were breastfed for 12-23 months (TCE = 1.13, 95% CI: 1.05-1.20) and for ≥24 months (TCE = 1.27, 95% CI: 1.14-1.40) presented a higher risk of caries at age of 2 years than those breastfed <12 months. However, this risk was slightly mediated by a decreased frequency of sugar consumption at age of 2 years only for breastfeeding from 12 to 23 months (NIE; OR = 0.95, 95% CI: 0.91-0.97). CONCLUSIONS: In this study, the effect of prolonged breastfeeding on the increased risk of dental caries was slightly mediated by sugar consumption. Early feeding practices for caries prevention and promoting breastfeeding while avoiding sugar consumption should be targeted in the first 2 years of life.

Adverse oral conditions associated with worse emotional and social well-being of Brazilian teenagers: a population-based study in a deprived rural-urban boundary / Condições bucais adversas associadas a pior bem-estar emocional e social de adolescentes brasileiros: um estudo de base populacional em uma periferia rural-urbana negligenciada

Abstract Background The relationship between dental appearance and emotional/social well-being in underprivileged areas undergoing rapid urbanization is unknown. Objective To assess if the emotional and social well-being of teenagers living in urban areas might be more affected by unfavorable dental appearance determined by oral conditions. Method A population-based cross-sectional exploratory study with 12-year-old Brazilian schoolchildren was carried out in two poor, underserviced districts of Sao Paulo City, Brazil. Outcome was severity of oral health-related quality of life (QHRQoL) due to the emotional and social well-being and exposures were oral conditions and residence district (rural or urban). Results The impact on severity of QHRQoL due to emotional well-being and due to social well-being, respectively, were 14% and 16% higher for those presenting at least one untreated decayed tooth; 36% and 54% higher for those with unfavorable dental appearance and 25% and 39% higher for those from the urban district. No association between malocclusion and district was observed. Conclusion Despite higher prevalence of untreated dental caries in the rural district, teenagers from the urban district felt that their OHRQoL, adjusted by oral conditions investigated, was more negatively affected. This suggests that urban environmental influences can lead to stressful social pressures stemming from dental appearance, leading to diminished emotional and social well-being.

Resumo Introdução A relação entre aparência dentária e bem-estar emocional/social em áreas carentes com urbanização acelerada é desconhecida. Objetivo Avaliar se o bem-estar emocional e social de adolescentes residentes em área urbana pode ser mais impactado pela aparência dentária desfavorável controlada pelas condições bucais. Método Um estudo exploratório transversal de base populacional envolvendo escolares brasileiros de 12 anos foi realizado em dois bairros carentes foi realizado, na cidade de São Paulo, Brasil. O desfecho foi a gravidade da qualidade de vida relacionada à saúde bucal (QVRSB) devido ao bem-estar emocional e social, e as exposições foram condições bucais e distrito de residência (rural e urbano). Resultados O impacto sobre a gravidade da QVRSB em decorrência do bem-estar emocional e do bem-estar social, respectivamente, foi 14% e 16% maior para aqueles que apresentavam pelo menos um dente cariado não tratado; 36% e 54% maior para aqueles com aparência dentária desfavorável e 25% e 39% maior para aqueles moradores em distrito urbano. Nenhuma associação entre má oclusão e distrito foi observada. Conclusão Apesar da maior prevalência de cárie dentária não tratada no distrito rural, os adolescentes do distrito urbano sentiram-se mais afetados negativamente em sua qualidade de vida relacionada à saúde bucal ajustada pelas condições bucais, sugerindo que as possíveis influências do ambiente urbano podem trazer experiências sociais estressantes devido à aparência dentária impactando no bem-estar emocional e social.

How oral health literacy and parental behavior during the meals relate to dental caries in children.

This cross-sectional study aimed to verify the influence of parental behavior on the development of dental caries in children by assessing parents' behavior during their children's meals and their parental level of oral health literacy. This study was conducted with children aged 2 to 4 in Diadema, São Paulo, Brazil. Six hundred and thirty children were examined to assess the prevalence of dental caries (dmft index). Parents answered a questionnaire related to socio-demographic conditions, oral health literacy (OHL), and the parents' behavior during the meal - Parent Mealtime Action Scale - (PMAS). The analysis fitted zero-inflated negative binomial regression (ZINB) models to assess unadjusted and adjusted associations between the study outcome and covariates. In the unadjusted analysis, the child's age, the number of siblings, household crowding, family income, socioeconomic status and OHL were associated with the outcome (p <0.05). In the adjusted model, dental caries was more prevalent among 3- (PR: 1.85, 95%CI: 1.19-2.87) and 4-year-old children (PR: 2.43, 95%CI: 1.60-3.71), those with at least one sibling (PR: 1.66, 95%CI:1.18-2.33). Poor children were more likely to have dental caries (PR: 0.66, 95%CI: 0.48-0.91); the Use of Rewards dimension of the PMAS was associated positively with dental caries severity (RR: 0.90, 95%CI: 0.84-0.97). Although OHL was not associated with caries, parents' mealtime behaviors were related to dental caries. This suggested that communication between parents and children related to good eating practices could play a protective role against dental caries in children.

Impact of the first thousand days of life on dental caries through the life course: a transdisciplinary approach.

This review aimed to describe the importance of the first 1000 days of a child's life as a golden period for interventions and actions to prevent dental caries and other chronic non-communicable diseases (NCDs) throughout the life course and highlight that the first 450 days of life could be even more important for oral health. During the first 1000 days of life (pregnancy and first two years of life), health care providers can identify unhealthy lifestyles, behaviors, and their determinants. Bearing in mind contextual factors like socioeconomic conditions and cultural aspects, this is a unique period to work together with the family and identify opportunities for adopting healthy habits that might last throughout the life of the expected or newborn child. This is a "window of opportunity" for the prevention of chronic NCDs of both systemic and oral origin, such as overweight, obesity, diabetes, cardiovascular diseases, and dental caries. In fact, to effectively prevent dental caries, pregnancy and the first 6 months of a child's life (first 450 days) should be considered the critical period to work together with families to facilitate the adoption of healthy habits. Knowledge about the first thousand days of life is essential and represents a crucial period for the implementation of actions and interventions that will guarantee good oral and general health development that can persist throughout life.

Relationship between oral health literacy of caregivers and the oral health-related quality of life of children: a cross-sectional study.

BACKGROUND: Oral health literacy is the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate oral health decisions. However, scientific evidence about the oral health literacy of caregivers and the children's oral health-related quality of life. The purpose of this study was to verify the relationship between the level of oral health literacy of caregivers and the children's oral health-related quality of life (OHRQOL). METHODS: This study was conducted with children aged 2 to 4 in Diadema, São Paulo, Brazil. Six hundred thirty children were examined to assess the prevalence of dental caries (dmft index). Parents were interviewed to obtain sociodemographic status, oral conditions, and oral health literacy (OHL). The variable outcome was the children's OHRQOL as assessed by the Early Childhood Oral Health Impact Scale (ECOHIS). We fitted zero-inflated negative binomial regression (ZINB) models to evaluate associations between the study outcome and covariates in terms of PR (Prevalence Ratios), RR (Rate Ratios), and their respective Confidence Intervals (95% CI). RESULTS: Children's OHRQOL was not associated with OHL. Dental caries had a negative impact on the children's quality of life (p < 0.05). A reduced impact on OHRQOL is also associated with having siblings (PR = 0.70, 95% CI 0.52-0.95). A higher age of the mother reduced OHRQOL impacts (PR = 0.72, 95% CI 0.52-0.98). CONCLUSIONS: The factors associated with children's OHRQOL were the number of siblings, the mothers' age, and dental caries. This study observed no association between parental OHL and children's OHRQOL.

Maternal-Child Health Indicators Associated with Developmental Defects of Enamel in Primary Dentition.

Purpose: To assess the prevalence and severity of developmental defects of enamel (DDE) in primary teeth and maternal-associated factors. Methods: This cross-sectional study included 336 two- to four-year-old children who attended the National Day of Children's Vaccination in São Paulo State, Brazil. The modified DDE index was used for diagnosis. Mothers completed sociodemographic and health questionnaires. Descriptive and Poisson regression analyses were performed. Results: The prevalence of DDE was 50.6 percent. The most frequent defects were demarcated opacities (45.0 percent), diffuse (36.0 percent) opacities, and hypoplasia (5.8 percent). White opacities were predominant (64.8 percent) in the teeth with defects, followed by cream (20.4 percent), yellow (5.2 percent), and brown (1.9 percent). Most defects involved less than one-third of the tooth surface (80.2 percent). The prevalence of DDE was associated with maternal-child factors such as alcohol consumption during pregnancy (prevalence ratio [PR] equals 1.27; 95 percent confidence interval [95% CI] equals 1.03 to 1.55), child hospitalization for infectious disease in the first year of life (PR equals 1.32; 95% CI equals 1.05 to 1.67), and breastfeeding for the first 12 months of life (PR equals 0.53; 95% CI equals 0.45 to 0.62). Conclusions: Developmental defects of enamel showed high prevalence and mild severity in the primary dentition. Alcohol consumption during pregnancy and child hospitalization for infectious diseases in the first year of life were associated with an increased prevalence of DDE. Moreover, children who breastfed for 12 months had a lower prevalence of DDE in primary teeth.

Changes in the Oral Health-Related Quality of Life in Infants With Cleft Lip and/or Palate Before and After Surgical Treatment.

OBJECTIVE: To assess oral health-related quality of life (OHRQoL) changes before and after the primary surgical treatment in infants with cleft lip and/or palate (CL/P). DESIGN: Quasi-experimental study. METHODS: A total of 106 infants with CL/P younger than 2 years undergoing primary surgical treatment in the Plastic Surgery Service of the Instituto Nacional de Salud del Niño in Peru. The parent/caregiver answered a questionnaire about OHRQoL named the Peruvian version of the Early Childhood Oral Health Impact Scale (P-ECOHIS) in the pretreatment (baseline) and follow-up post-treatment. The total score of P-ECOHIS and their 2 sections (child impact and family impact) in the baseline and each follow-up period post-treatment scores were assessed. As well as, the type of the CL/P on OHRQoL, standardized effect sizes (ES) based on mean total change scores (difference between baseline and 12th month) were analyzed. RESULTS: Improvements in infant's OHRQoL after treatment were reflected in each follow-up period P-ECOHIS score compared to the baseline score. The total P-ECOHIS scores decreased significantly from 28.07 (baseline) to 7.7 (12th month; P < .0001), as did the individual domain scores (P < .0001). There were significant differences in the baseline and follow-up post-treatment scores of infants who reported improvement of the OHRQoL (P < .0001). The ES was large (3.79). The cleft lip had an improvement in the OHRQoL at 12th month post-treatment (P < .0001). CONCLUSIONS: Primary surgical post-treatment resulted in significant improvement of the infant's OHRQoL with CL/P.

Although OHL was not associated with caries, parents' mealtime behaviors were related to dental caries. This suggested that communication between parents and children related to good eating practices could play a protective role against dental caries in children.

Does fluorosis have an impact on Peruvian children's oral health related quality of life? / Fluorose dentária tem impacto na qualidade de vida relacionada à saúde bucal de crianças peruanas?

ABSTRACT Objectives The aims of this study were to evaluate the prevalence and severity of dental fluorosis and to assess the impact of dental fluorosis on oral health related quality of life (OHRQoL) of children living in two Peruvian towns with different water fluoride levels. Methods A sample of 292 children between 11 and 14 years of age and both genders were selected among public and private primary schools in the 2 towns. Clinical oral examination was carried out using Dean's index to assess the prevalence and severity of dental fluorosis and the Child Perceptions Questionnaire 11-14 (CPQ 11-14) was used to evaluate the association between dental fluorosis and OHRQoL. Results Dental fluorosis prevalence was 75% and the moderate score was the most frequent (36%). The two towns have a low socioeconomic level and children from public schools predominate (74%). There was no impact of fluorosis on OHRQoL. It is possible that adolescents living in a context with very similar dental appearance of their peers build a sense of identity different than other populations, which can influence in their OHRQoL perception. Conclusions Even though dental fluorosis prevalence was very high it did not have impact on OHRQoL.

RESUMO Objetivos Os objetivos deste estudo foram avaliar a prevalência e a gravidade da fluorose dentária e avaliar o impacto da fluorose dentária na qualidade de vida relacionada à saúde bucal (QVRSB) de crianças residentes em duas cidades peruanas com diferentes níveis de flúor de água. Métodos Uma amostra de 292 crianças entre 11 e 14 anos de idade e ambos os sexos foram selecionada nas escolas públicas e privadas de ensino fundamental nas duas cidades. O exame oral clínico foi realizado utilizando-se o índice de Dean para avaliar a prevalência e a gravidade da fluorose dentária e o Questionário de Percepção Infantil 11-14 (CPQ 11-14) para avaliar a associação entre fluorose dentária e QVRSB. Resultados A prevalência de fluorose dentária foi de 75% e o escore moderado foi o mais frequente (36%). As duas cidades têm baixo nível socioeconômico e predominam as crianças de escolas públicas (74%). Não houve impacto da fluorose na QVRSB. É possível que os adolescentes que vivem em um contexto social em que a aparência dentária seja muito semelhante entre as pessoas tenham um senso de identidade diferente de outras sociedades, o que pode influenciar em sua percepção de QVRSB. Conclusão Embora a prevalência de fluorose dentária tenha sido muito alta, não teve impacto na QVRSB.

Follow-up interval for dental appointments: a randomized clinical trial with children with low caries risk

Abstract The objective of this study was to evaluate the effect of different follow-up consultation intervals on caries incidence in children with low caries risk. The study was composed of 224 children aged between 3 and 5 years and with low risk of caries. The children were randomly allocated into two groups, according to two different follow-up consultation intervals: Group 1 (G1) - 12-month follow-up interval; Group 2 (G2) - 18-month follow-up interval. All oral clinical examinations were performed by a single examiner who was previously calibrated and blinded in relation to the study groups. An external dentist provided the advice on oral hygiene and diet and evaluated the children's socioeconomic conditions. The Chi-square and Mann-Whitney tests were used to evaluate the differences between groups. Poisson regression analyses were performed to assess the association of caries incidence with the other variables. At the end of the study there was a significant difference between the groups regarding initial active lesions (p = 0.012), and children in G2 were at a higher risk of developing initial active lesions than those in G1 (p = 0.047). Children who had a higher number of teeth with initial active lesions in the follow-up consultations were at a higher risk of developing cavitated dentin caries (p = 0.001). Both follow-up intervals are justifiable. Although significant results have been observed for initial active caries lesions within the 18-month follow-up interval, it should be noted that these lesions can be treated using just preventive measures. Besides, different return interval had no effect in cavitated dentin lesions.

Survival rate of pulpectomy in primary teeth using Feapex® paste: a clinical study in infants / Sobrevida de pulpectomia em dentes decíduos utilizando pasta Feapex®: um estudo clínico em bebês

Objective: The aim of this clinical study was to evaluate the survival rate of a new pulpectomy protocol using 2% chlorhexidine digluconate gel and Feapex® paste for endodontic treatment in primary teeth. Material and Methods: A total of 105 pulpectomies were performed in anterior and posterior teeth of 48 infants (1-3 years old) with high caries experience with irreversible pulpitis or pulp necrosis. All treatments were performed by dental surgeons with no specialization in Pediatric Dentistry, under local anesthesia and rubberdam isolation. Manual files were used in conjunction with 2% chlorherixidine gel for root canal instrumentation, and Feapex® paste was used as a obturation material. The clinical and radiographic outcomes were collected by one trained independent evaluator with a follow-up period of 24months. Success was determined by the absence of pain, pathological mobility, pathologic bone rarefaction, pathological root resorption and soft tissue pathology around the affected tooth Survival of the endodontic treatment was evaluated by estimating survival rates through Kaplan-Meier curves. Cox Regression analysis with shared fragility were performed to evaluate the association between the independent variables to endodontic treatment failure (α=5%). Results: After 24 months, the treatment survival was 86% (SE=0.03). Root resorption at baseline was associated with a higher risk of failure (HR=2.81; CI=1.12-7.08; p=0.027). The survival rate of the endodontic treated teeth due to dental trauma was 100%, while teeth with dental caries had lower survival rate (85.05%; p<0.001*). Other variables analyzed included gender, age of the child, tooth position (incisor/molar), restoration type, obturation quality, and caries experience were not associated with treatment failure (p>0.05). Conclusion: The new protocol using 2% chlorhexidine digluconate and Feapex® presented a high survival rate and can be considered as a suitable protocol for pulpectomy in primary teeth.Trial Registration: REBEC (RBR-282s2f) (AU)

Objetivo: Avaliar a sobrevida de um novo protocolo para tratamento endodôntico (pulpectomia) em dentes decíduos utilizando gel de digluconato de clorexidina 2% e pasta Feapex®. Material e Métodos: Um total de 105 pulpectomias foram realizadas em dentes anteriores e posteriores diagnosticados com pulpite irreversível ou necrose pulpar em 48 crianças (1-3 anos de idade) com alta experiência de cárie. Todos os tratamentos foram realizados por cirurgiões-dentistas clínicos gerais, sob anestesia local e isolamento absoluto. Limas manuais foram utilizadas em conjunto com cloroherixidina 2% gel para instrumentação dos canais radiculares e pasta Feapex® foi utilizada como material de obturação. Os resultados clínicos e radiográficos foram coletados por um avaliador independente treinado com um período de acompanhamento de 24 meses. O sucesso foi determinado pela ausência de dor, mobilidade patológica, rarefação óssea patológica, reabsorção radicular patológica e ausência de fístula/abscesso ao redor do dente tratado. A sobrevida do tratamento endodôntico foi estimativa utilizando curvas de Kaplan-Meier. Análise de regressão de Cox com fragilidade compartilhada foi realizada para avaliar a associação entre as variáveis independentes com a falha do tratamento endodôntico (α = 5%). Resultados: Após 24 meses, a sobrevida do tratamento foi de 86% (EP = 0,03). A reabsorção radicular no início do estudo foi associada a um maior risco de falha (HR= 2,81; IC= 1,12-7,08; p= 0,027). Dentes tratados endodonticamente devido ao traumatismo dentário na dentição decídua apresentaram taxa de sobrevida de 100%, enquanto dentes com comprometimento pulpar devido à cárie dentária tiveram menor sobrevida (85,05%; p<0,001 *). Todas as outras variáveis analisadas como sexo, idade da criança, dente (incisivo/molar), tipo de restauração, qualidade da obturação e experiência de cárie não foram associadas à falha do tratamento (p> 0,05). Conclusão: O novo protocolo utilizando digluconato de clorexidina 2% e Feapex® apresentou alta sobrevida e pode ser considerado um protocolo adequado para pulpectomia em dentes decíduos.Registro do estudo clínico: REBEC (RBR-282s2f).

Follow-up interval for dental appointments: a randomized clinical trial with children with low caries risk.

The objective of this study was to evaluate the effect of different follow-up consultation intervals on caries incidence in children with low caries risk. The study was composed of 224 children aged between 3 and 5 years and with low risk of caries. The children were randomly allocated into two groups, according to two different follow-up consultation intervals: Group 1 (G1) - 12-month follow-up interval; Group 2 (G2) - 18-month follow-up interval. All oral clinical examinations were performed by a single examiner who was previously calibrated and blinded in relation to the study groups. An external dentist provided the advice on oral hygiene and diet and evaluated the children's socioeconomic conditions. The Chi-square and Mann-Whitney tests were used to evaluate the differences between groups. Poisson regression analyses were performed to assess the association of caries incidence with the other variables. At the end of the study there was a significant difference between the groups regarding initial active lesions (p = 0.012), and children in G2 were at a higher risk of developing initial active lesions than those in G1 (p = 0.047). Children who had a higher number of teeth with initial active lesions in the follow-up consultations were at a higher risk of developing cavitated dentin caries (p = 0.001). Both follow-up intervals are justifiable. Although significant results have been observed for initial active caries lesions within the 18-month follow-up interval, it should be noted that these lesions can be treated using just preventive measures. Besides, different return interval had no effect in cavitated dentin lesions.

Oral health-related quality of life among pediatric liver transplant candidates.

To assess the impact of oral conditions on the oral health-related quality of life (OHRQoL) of pediatric liver transplant candidates. This cross-sectional study included 60 children aged 13 to 48 months who were liver transplant candidates that attended the AC Camargo Cancer Center, São Paulo, Brazil. On the day of oral examinations, the children's mothers were invited to answer two questionnaires; one related to children's OHRQoL using the B-ECOHIS and another related to socioeconomic/demographic characteristics. Thereafter, a single, adequately trained dentist carried out children's oral examinations for gingival inflammation (Silness-Löe index), dental plaque (Green-Vermillion Simplified index), dental caries (dmft index), developmental defects of enamel (DDE index), tooth discoloration, oral mucosal/lip alterations. The data collected also included socioeconomic/demographic characteristics and liver disease. The adjusted Poisson regression model was used to associate children's socioeconomic/demographic characteristics and clinical conditions to the outcome. The adjusted regression model showed that children with untreated caries lesions (RR = 3.35, p < 0.0001) and tooth discoloration (RR = 1.74, p = 0.04) had poorer total B-ECOHIS scores. Dental discoloration and untreated caries lesions had a negative impact on the OHRQoL in pediatric liver transplant candidates.

The Impact of Temporomandibular Disorders on the Oral Health-Related Quality of Life of Brazilian Children: A Cross-Sectional Study.

Purpose: To evaluate the prevalence of signs and symptoms of temporomandibular disorders (TMD) in children and the impact on their oral health-related quality of life (OHRQoL).
Methods: Data were collected by means of a questionnaire to evaluate the presence of TMD symptoms in eight to 10-year-old children. For those who answered at least one of the four questions in a positive manner, a clinical exam was done to confirm the diagnosis. The Child Perceptions Questionnaire (CPQ8-10) was applied to evaluate the OHRQoL. Poisson regression was used to associate the total scores and individual domains of the CPQ8-10 with sociodemographic factors and clinical conditions.
Results: A total of 245 children participated in this cross-sectional study. One hundred and twenty-one (49.4 percent) were diagnosed with TMD; 57.9 percent were females and 42.1 percent were males. Children with a diagnosis of disc displacement with reduction had a negative impact on the domain of functional limitations (rate ratio=2.61, 95 percent confidence interval=1.19 to 5.75, P =0.017).
Conclusion: The prevalence of signs and symptoms of TMD was high in our sample, and signs and symptoms of TMD had a negative impact on children's OHRQoL in the domain of functional limitations.
