Abstract 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.

Resumo O objetivo do estudo foi investigar as características socioeconômicas e obstétricas de parturientes adolescentes e suas complicações sobre a saúde materna e neonatal. 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.

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.

Abstract 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.

Abstract 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.

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.

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.

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.

Abstract 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.

There is no study assessing the impact of dental caries (DC), dental fluorosis (DF) and traumatic dental injuries (TDI) on oral health-related quality of life (OHRQoL) in school children from Colombia. The purpose of this study was to assess the impact of DC, DF and TDI on Colombian schoolchildren's OHRQoL using their parents as proxies. The parents of338 children aged 6 to 14 years from public and private schools of Cartagena, Colombia answered the Parental-Caregiver Perception Questionnaire (P-CPQ) on child's OHRQoL adapted to Colombian Spanish language and a socioeconomic questionnaire. Three calibrated examiners performed the clinical assessment for DC, DF and TDI. Poisson regression associated clinical and socioeconomic conditions to the outcome. Overall, 90.24% of parents reported children's oral impact (total P-CPQ score ≥ 1). The mean (standard deviation) P-CPQ scores were 12.49 (14.04). The multivariate adjusted model showed that children from public schools and who have dental caries experience (RR= 1.28; p=0.04 andRR= 1.37;p= 0.018, respectively) were more likely to experience negative impact on total P-CPQ scores. DC was found to be associated to parental-caregiver perception of impact on their children's oral health-related quality of life, but DF and TDI were not.

No existen estudios que evalúen el impacto de la caries dental (CD), la fluorosis dental (FD) y el trauma dentoalveolar (TDA) sobre la calidad de vida relacionada con la salud bucal (CVRSB) de escolares de Colombia que pertenece a países de habla hispana. El propósito de este estudio fue evaluar el impacto de la caries dental (CD), la fluorosis dental (FD) y el trauma dentoalveolar (TDA) sobre la calidad de vida relacionada con la salud bucal de escolares colombianos usando sus padres como proxies. Los padres de 338 niños y niñas de 6 a 14 años de escuelas públicas y privadas de Cartagena, Colombia, contestaron el Parental-Caregivers Perception Questionnaire (P-CPQ) on child's OHRQoL adaptado al español colombiano y un cuestionario socioeconómico. Tres examinadores calibrados realizaron la evaluación clínica para CD, FD y TDA. La regresión de Poisson asoció las condiciones clínicas y socioeconómicas al puntaje total del P-CPQ y sus dominios. En general, el 90,24% de los padres reportaron el impacto oral de los niños sobre la calidad de vida (puntaje P-CPQ total ≥ 1). La media (DE) del P-CPQ fue de 12,49 (14,04). El modelo multivariado ajustado mostró que los niños de escuelas públicas que tenían experiencia de caries dental (RR = 1,28, p = 0,04 y RR = 1,37, p = 0,018, respectivamente) tuvieron mayorprobabi-lidad de experimentar un impacto negativo en las puntuaciones totales del P-CPQ. La CD mostró asociación con la percepción del impacto de los padres-cuidadores sobre la salud oral de sus hijos en relación con la calidad de vida. Sin embargo, FD y TDA no se encontraron asociados.

There is no study assessing the impact of dental caries (DC), traumatic dental injuries (TDI) and dental malocclusions (DM) on the oral health-related quality of life (OHRQoL) of preschool children from Spanish-speaking countries in population-based samples. The purpose of this study was to assess the impact of DC, TDI and DM, on Colombian preschool children's OHRQoL through a cross-sectional study. The clinical setting included private and public preschools in Cartagena,Colombia. The sample included 643 preschool children aged 1-5 years and their parents, who answered the Colombian version of the Early Childhood Oral Health Impact Scale (C-ECOHIS) and socioeconomic questionnaire. Three calibrated examiners performed clinical assessment of severity of DC according to decayed, missing and filled primary teeth index, TDI and DM. Poisson regression associated clinical and socio economic conditions to the outcome. Overall, 48. 2% of parents reported children's oral impacts (total C-ECOHIS score >1). The mean (standard deviation) C-ECOHIS scores were 2. 20 (0. 15). The multivariate adjusted model showed that children from non-nuclear families (RR=1. 51; p=0. 003),with low and high DC severity (RR=1. 51, p=0. 003; RR=1. 53, p=0. 009) and TDI (RR=1. 56, p=0. 003), were more likely to experience negative impact on total C-ECOHIS scores. DC and TDI have negative impact on Colombian preschool children's OHRQoL. Children from non-nuclear families have worse OHRQoL at this age, independently of the presence of oral conditions.

No existen estudios que evalúen el impacto de la caries dental (CD), el trauma dentoalveolar (TDA) y las maloclusiones dentales (MD) sobre la calidad de vida relacionada con la salud bucal (CVRSB) en niños preescolares en muestras de poblaciones de países hispanohablantes. El propósito de este estudio fue evaluar el impacto de CD, TDA y MD sobre la CVRSB en niños colombianos en edad preescolar a través de un estudio transversal. Las evaluaciones clínicas se realizaron en colegios privados y públicos de Cartagena, Colombia, en una muestra de 643 niños en edad de 1-5 años y sus padres quienes respondieron la versión colombiana de la Escala Early Childhood Oral Health Impact Scale (C-ECOHIS) y un cuestionario socioeconómico. Tres examinadores calibrados realizaron la evaluación clínica de la severidad de CD acorde con el Indice ceod para dentición decidua, TDA y MD. La regresión de Poisson asoció las condiciones clínicas y socioeconómicas al puntaje total del C-ECOHIS y sus dominios. En general, el 48,2% de los padres reportaron impactos orales de los niños (puntuación C-ECOHIS total >1). La media (DE) del C-ECOHIS fué de 2,20 (0,15). El modelo multivariado ajustado mostró que los niños de familias no nucleares (RR = 1,51; p = 0,003), que tienen baja y alta severidad de CD (RR = 1,51, p = 0,003; RR = 1,53, p = 0,009) y TDA(RR = 1,56, p = 0,003) tuvieron mayor probabilidad de experimentar un impacto negativo en las puntuaciones totales de C-ECOHIS. La CD y la TDA tienen un impacto negativo sobre la CVRSB en niños preescolares colombianos. Los niños de familias no nucleares tienen peor CVRSB a esta edad, independientemente de la presencia de las condiciones orales.

RESUMO Objetivo: O objetivo deste estudo foi investigar o impacto das lesões de desgaste dentário erosivo na qualidade de vida relacionada à saúde bucal (QVRSB) de pré-escolares. Métodos: Exames clínicos foram conduzidos em 815 crianças de 3 e 4 anos de idade durante a Campanha Nacional de Multivacinação Infantil. Os pais ou responsáveis foram convidados a responderam a versão brasileira do Early Childhood Oral Health Impact Scale (B-ECOHIS). A prevalência e a gravidade das lesões de desgastes dentários erosivos foram avaliadas de acordo com o índice de O’Brien (1994). Também foram coletados dados socioeconômicos e variáveis da criança. A QVRSB foi mensurada por meio dos domínios e escore total do B-ECOHIS. A análise de regressão de Poisson foi adotada para associar as lesões de desgaste dentário erosivo ao desfecho e ajustada para cárie dentária e lesões dentárias traumáticas. Resultados: A proporção de crianças que apresentavam pelo menos 1 dente apresentando desgaste dentário erosivo foi 51,2%. A maioria das lesões de desgaste dentário erosivo estava confinada ao esmalte (42,7%). A análise ajustada multivariada revelou que apenas que a idade (crianças de 4 anos) foi associada a um impacto negativo nos domínios de sintomas (RR=1,70; p=0,010), limitação funcional (RR=1,85; p=0,005) e escore total do B-ECOHIS (RR= 1,63; p=0,006). Famílias com 2 ou mais filhos tiveram um impacto negativo nos dominíos de autoestima e interação social (RR=5,41; p=0,043). As lesões de desgaste dentário erosivo não foram associadas ao escore total de B-ECOHIS (RR= 0,79; p=0,163) e domínios individuais. Conclusão: As lesões de desgaste dentário erosivo não afetaram a qualidade de vida de pré-escolares da amostra estudada.

ABSTRACT Objective: The aim of this study was to investigate the impact of erosive tooth wear on the Oral Health-Related Quality of life (OHRQoL) of preschool children. Methods: Dental examinations were conducted on 815 children aged 3-4 years during the Children’s Vaccination National Day when their parents were also invited to answer the Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS). ETW prevalence and severity were measured using a modified version of the O’Brien index (1994). Data collected included socioeconomic factors and child's variables. OHRQoL was measured through B-ECOHIS domains and total score. Poisson regression was used to associate ETW to the outcome and this association was adjusted for dental caries and dental trauma. Results: The proportion of children who had at least 1 ETW tooth was 51.2%. Most erosive lesions were confined to enamel (42.7%). The multivariate adjusted model showed that child's age (children aged 4year-old) was associated to a negative impact on the symptom domain (RR=1.70; p=0.010), functional limitation domain (RR=1.85; p=0.005) and total B-ECOHIS score (RR= 1.63; p=0.006). Families with 2 or more children in the house have a negative impact on the self-image/social interaction domain (RR=5.41; p=0.043). ETW was not associated to total B-ECOHIS scores (RR= 0.79; p=0.163) and individual domains. Conclusion: Erosive tooth wear does not affect the OHRQoL in this sample of preschool children.

Abstract The aim of this study was to assess the clinical and socioeconomic indicators associated with dental anxiety in preschool children with severe dental caries. A total of 100 children between 3 and 5 years of age were selected during a dental screening procedure. The selection criteria were having at least one tooth with dental caries and a visible pulpal involvement, ulceration, fistula, and abscess (PUFA) index of ≥1 in primary teeth. Before the clinical examination or any treatment procedure was performed, we evaluated the children’s dental anxiety using the Facial Image Scale (FIS). Parents completed a questionnaire on socioeconomic conditions, which included the family structure, number of siblings, parental level of education, and family income. A dentist blinded to FIS and socioeconomic data performed the clinical examination. Poisson regressions associate clinical and socioeconomic conditions with the outcome. Most of the children (53%) experienced extensive dental caries (dmf-t ≥ 6), and all children had severe caries lesions, with a PUFA index of ≥1 in 41% and that of ≥2 in 59%. The multivariate adjusted model showed that older children (4–5-year old) experienced lower dental anxiety levels compared with younger children (3-year old) (RR = 0.35; 95%CI: 0.17–0.72 and RR = 0.18; 95%CI: 0.04–0.76, respectively), and children with three or more siblings were associated with higher levels of dental anxiety (RR = 2.27; 95%CI: 1.06–4.87). Older age is associated with low dental anxiety, and more number of siblings is associated with high dental anxiety in preschool children, whereas the severity or extent of dental caries is not associated with dental anxiety.

RESUMO A cárie dentária é uma doença não infecciosa e é considerada um problema de saúde pública. Para seu diagnóstico e correto tratamento é necessário a avaliação do risco e da atividade da doença cárie. A avaliação do risco de cárie é uma maneira de formalizar o equilíbrio e desequilíbrio da doença de modo previsível para realizar o diagnóstico da doença presente. Para tanto, a avaliação do risco de cárie é realizada através de diferentes sistemas. Outro parâmetro de grande importância a ser estudado é a atividade da doença cárie, pois através dela é realizada a correta decisão de tratamento para o paciente. Assim, o objetivo do presente artigo foi informar ao leitor: os conceitos e fatores de risco de cárie; os diferentes sistemas de avaliação de risco de cárie descritos na literatura; e quais sistemas são validados. Contudo, esta revisão de literatura proporciona a identificação e avaliação dos fatores de risco e atividade das lesões de cárie afim de possibilitar uma maior objetividade no diagnóstico e facilitar as decisões de um tratamento bem-sucedido.

ABSTRACT Dental caries is a non-communicable disease and is considered a public health problem. For diagnosis and correct treatment, the study of risk assessment and caries activity is necessary. The caries risk assessment is a way to formalize the balance and imbalance of predictably disease to diagnose dental caries. Therefore, the caries risk assessment is performed through different evaluation systems. Another parameter of great importance to be studied is the activity of caries, because through it is done the correct treatment decision for the patient. The objective of this article is to inform the reader about: the concepts and caries risk factors; the different caries risk assessment systems described in the literature; and which systems are validated. In addition, this literature review provides for identification and evaluation of risk factors and activity of caries lesions in order to enable greater objectivity in the diagnosis and facilitate the decisions of a successful treatment.

The lack of a Family Impact Scale (FIS) in Spanish language limits its use as an indicator in Spanish-speaking countries and precludes comparisons with data from other cultural and ethnic groups. The purpose of this study was therefore to adapt the FIS cross-culturally to the Peruvian Spanish language and assess its reliability and validity. In order to translate and adapt the FIS cross-culturally, it was answered by 60 parents in two pilot tests, after which it was tested on 200 parents of children aged 11 to 14 years who were clinically examined for dental caries experience and malocclusions. Internal consistency was assessed by Cronbach’s alpha coefficient while repeat administration of the FIS on the same 200 parents enabled the test-retest reliability to be assessed via intraclass correlation coefficient (ICC). Construct and discriminant validity were based on associations of the FIS with global ratings of oral health and clinical groups, respectively. Mean (standard deviation) FIS total score was 5.20 (5.86). Internal consistency was confirmed by Cronbach’s alpha 0.84. Test-retest reliability revealed excellent reproducibility (ICC = 0.96). Construct validity was good, demonstrating statistically significant associations between total FIS score and global ratings of oral health (p=0.007) and overall wellbeing (p=0.002), as well as for the subscale scores (p<0.05) with exception of the financial burden subscale. The FIS was also able to discriminate between children with and without dental caries experience and malocclusions (p<0.05). Satisfactory psychometric results for the Peruvian Spanish FIS confirm it as a reliable, valid instrument for assessing the impact on the family caused by children’s oral conditions.

La falta de la Escala de Impacto Familiar (FIS) en el idioma espanol limita su uso como indicador en paises hispanohablantes, asi como impide las comparaciones con diferentes grupos culturales y etnicos. Por lo tanto, el objetivo de este estudio fue adaptar transculturalmente el FIS al idioma espanol de Peru y evaluar su validad y confiabilidad. Para traducir y adaptar transculturalmente el FIS, 60 padres respondieron al instrumento en dos pruebas piloto. Posteriormente, el FIS fue probado en 200 padres de ninos de 11 a 14 anos de edad, quienes fueron clinicamente evaluados para la experiencia de caries dental y maloclusiones. La consistencia interna fue evaluada por el coeficiente alfa de Cronbach, mientras que la re-aplicacion del FIS en los mismos 200 padres permitio la evaluacion de la confiabilidad testretest por medio del coeficiente de correlacion intraclase (CCI). La validez de constructo y discriminante se basaron en las asociaciones del FIS con las puntuaciones globales de salud bucal y grupos clinicos, respectivamente. La media (desviacion estandar) de la puntuacion total del FIS fue 5,20 (5,86). La consistencia interna fue confirmada por el alfa de Cronbach de 0,84. La confiabilidad test-retest revelo una excelente reproducibilidad (CCI=0,96). La validez de constructo fue buena, demostrando una asociacion estadisticamente significativa entre la puntuacion total del FIS y las puntuaciones globales de salud bucal (p=0,007), bienestar (p=0,002), asi como para las puntuaciones de las sub-escalas (p<0,05), con excepcion de la sub-escala de carga financiera. El FIS fue capaz de discriminar ninos con y sin caries dental y maloclusiones (p<0,05). Los resultados psicometricos satisfactorios de la version peruana del FIS confirman que es un instrumento valido y confiable para evaluar el impacto en la familia causado por las condiciones bucales de los ninos.

Parents may feel guilty about their children's oral problems, which can affect their quality of life. The aim of this study was to assess the presence of parental guilt and its association with early childhood caries (ECC), traumatic dental injuries (TDI) and malocclusion (AMT) in preschool children. All 2 to 5 year-old children (N = 305), and their parents, seeking dental care at the University of São Paulo Dental School one-week Screening Programme, were asked to participate in the study, and 260 agreed. Children were examined by two calibrated dentists, and their parents answered a socioeconomic and ECOHIS questionnaire; the question on guilt was used as the dependent variable. Regression analyses examined the association between parental guilt and ECC, TDI, AMT and socioeconomic factors. A total of 35.8% of parents felt guilty. This was only associated with caries severity. No association was found between guilt and TDI, AMT or socioeconomic factors. ECC was present in 63.8% of the children; the mean (± sd) dmf-t score was 7.29 (± 2.78). Thus, the number of parents feeling guilty increases with the increase of their children's dental caries severity. Parental guilt is related to caries but is not associated with TDI or AMT.
