Traumatic dental injuries in Brazilian children and oral health-related quality of life.

BACKGROUND/AIMS: Population-based studies that investigate the impact of TDI on oral health-related quality of life (OHRQoL) among school children and its association with socioeconomic factors are scarce and offer conflicting results. The aim of this study was to evaluate the impact of TDI on OHRQoL among school children and its association with socioeconomic status. MATERIALS AND METHODS: A cross-sectional study was conducted with 588 12-year-old children enrolled in public and private schools in the urban areas in the city of Diamantina (southeastern Brazil). Clinical examinations were performed for the diagnosis of traumatic dental injury based on Andreasen's classification. The Child Perceptions Questionnaire (CPQ11-14 ), which has been validated for the population in Brazil, was employed to evaluate oral health-related quality of life. Socioeconomic status and overjet were also analyzed. Statistical analysis involved the chi-square test and logistic regression. RESULTS: A total of 29.4% of the students exhibited some type of trauma to at least one tooth. A negative impact on oral health-related quality of life was found in 53.1% of the sample. Traumatic dental injury was associated with a high impact on oral health-related quality of life [OR = 1.61 (95% CI: 1.08-2.39)] and overjet >3 mm [OR = 5.42 (95% CI: 3.66-8.02)]. However, no statistically significant associations were found between TDI and socioeconomic status. CONCLUSIONS: Prevalence of traumatic dental injury was high among the children who participated in the study, and it was associated with a high impact on oral health-related quality of life as well as overjet >3 mm.

Cross-cultural adaptation and psychometric properties of the Brazilian version of the scale of oral health outcomes for 5-year-old children (SOHO-5).

BACKGROUND: Most of the instruments available to measure the oral health-related quality of life (OHRQoL) in paediatric populations focus on older children, whereas parental reports are used for very young children. The scale of oral health outcomes for 5-year-old children (SOHO-5) assesses the OHRQoL of very young children through self-reports and parental proxy reports. We aimed to cross-culturally adapt the SOHO-5 to the Brazilian Portuguese language and to assess its reliability and validity. FINDINGS: We tested the quality of the cross-cultural adaptation in 2 pilot studies with 40 children aged 5-6 years and their parents. The measurement was tested for reliability and validity on 193 children that attended the paediatric dental screening program at the University of São Paulo. The children were also clinically examined for dental caries. The internal consistency was demonstrated by a Cronbach's alpha coefficient of 0.90 for the children's self-reports and 0.77 for the parental proxy reports. The test-retest reliability results, which were based on repeated administrations on 159 children, were excellent; the intraclass correlation coefficient was 0.98 for parental and 0.92 for child reports. In general, the construct validity was satisfactory and demonstrated consistent and strong associations between the SOHO-5 and different subjective global ratings of oral health, perceived dental treatment need and overall well-being in both the parental and children's versions (p<0.001). The SOHO-5 was also able to clearly discriminate between children with and without a history of dental caries (mean scores: 5.8 and 1.1, respectively; p<0.001). CONCLUSION: The present study demonstrated that the SOHO-5 exhibits satisfactory psychometric properties and is applicable to 5- to 6-year-old children in Brazil.

Development of a short form of the Brazilian Parental-Caregiver Perceptions Questionnaire using exploratory and confirmatory factor analysis.

PURPOSE: This study presents the Brazilian short form of the P-CPQ. METHODS: Data from a representative sample of 702 parents/caregivers of children were randomly divided in two subsamples. A development sample (n = 502) was used for exploratory factor analysis (EFA), and a validation sample (n = 200) was used for confirmatory factor analysis (CFA). The EFA was used to determine the hypothetical factor structure and internal consistency. The CFA was applied to test the factor structure of the original P-CPQ, alternative models and the validity and reliability of the Brazilian short form of the P-CPQ. RESULTS: A 3-factor model (alternative model 2) had a factor structure with high factor loadings, acceptable fit indices (χ(2)/df = 2.38; GFI = 0.90; CFI = 0.90; TLI = 0.87; AGFI = 0.85; SRMR = 0.07) and both convergent and discriminant validity (Pearson bivariate zero order correlations among factors <0.85). CONCLUSIONS: The Brazilian P-CPQ with three subscales and 13 items appears to be a valid short version to be used in further studies to evaluate parents/caregivers' perceptions of children's oral health-related quality of life.

Agreement between adolescents' and their mothers' reports of oral health-related quality of life.

The aim of this study was to determine the level of agreement between reports by adolescents and their mothers regarding the impact of oral health on the adolescents' quality of life. The sample consisted of 960 pairs of adolescents aged 11 to 14 years and their mothers. The Brazilian version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ) and the short form of the Child Perceptions Questionnaire (CPQ11-14) were administered. Agreement on the total scale and the subscales was determined through a comparison of mean values. The means of the directional and absolute differences were also determined. Agreement on each item on the group level and in the individual pairs was analyzed using the Intraclass Correlation Coefficient (ICC). The difference between the means and the directional differences were significant for the total score as well as for the functional limitation and social well-being subscales (p < 0.001). The ICC for the total P-CPQ and CPQ11-14 scores was 0.43. The ICC indicated weak agreement on the subscales, ranging from 0.36 to 0.40. Agreement between reports by adolescents and their mothers regarding oral health-related quality of life (OHRQoL) was moderate, indicating that both perspectives should be considered.

Oral health-related quality of life of paediatric patients with AIDS.

BACKGROUND: Children with Acquired Immune Deficiency Syndrome (AIDS) exhibit impaired dental status, which can affect their quality of life. This study assessed the oral health-related quality of life of these patients and associated factors. METHODS: The "Child Perceptions Questionnaire 11-14", rating overall and domain-specific (oral symptoms, functional limitations, emotional well being, and social well being) oral health-related quality of life (OHR-QoL) was completed by 88 children with AIDS assisted in the Child Institute, Sao Paulo, Brazil. Parents or guardians provided behavioural and socio-demographic information. The clinical status was provided by hospital records. OHR-QoL covariates were assessed by Poisson regression analysis. RESULTS: The most affected OHR-QoL subscale concerned oral symptoms, whose rate was 23.9%. The direct answer for oral health and well being made up a rate of 47.7%. Brushing the teeth less than two times a day and viral load exceeding 10,000 HIV-RNA copies per millilitre of plasma were directly associated (p < 0.05) with a poorer oral health-related quality of life. CONCLUSIONS: Children with more severe AIDS manifestations complained of poorer status of oral symptoms, functional limitations, emotional and social well being related to their oral health. Recognizing the factors that are associated with poorer OHR-QoL in children with AIDS may contribute to the planning of dental services for this population.

Association between treated/untreated traumatic dental injuries and impact on quality of life of Brazilian schoolchildren.

BACKGROUND: Traumatic dental injury (TDI) could have physical and psychosocial consequences for children. Thus, it is important to measure the impact of TDI on the quality of life of children (QoL). The aim of the present study was to investigate the association between treated/untreated TDI and the impact on the quality of life of 11-to-14-year-old Brazilian schoolchildren. METHODS: A cross-sectional study was carried out involving 1612 male and female schoolchildren aged 11 to 14 years attending public and private elementary schools in the city of Belo Horizonte, Brazil. A multi-stage sampling technique was adopted to select the children. Three calibrated examiners used the Andreasen classification for the diagnosis of TDI. Oral health-related quality of life was assessed using the Brazilian version of the Child Perceptions Questionnaire (CPQ11-14) - Impact Short Form (ISF:16), composed of 16 items and self-administered by all children. Other oral conditions (dental caries and malocclusion) and the Social Vulnerability Index were determined and used as controlling variables. RESULTS: Two hundred nineteen children were diagnosed with untreated TDI and 64 were diagnosed with treated TDI. There were no statistically significant associations between untreated or treated TDI and overall CPQ11-14 (Fisher = 0.368 and Fisher = 0.610, respectively). Children with an untreated TDI were 1.4-fold (95% CI = 1.1-2.1) more likely to report impact on the item "avoided smiling/laughing" than those without TDI, whereas children with a treated TDI were twofold (95% CI = 1.1-3.5) more likely to report impact on the item "other children asked questions" than those without TDI. CONCLUSIONS: Neither treated nor untreated TDI was associated with oral symptoms, functional limitations or emotional wellbeing. However, children with a TDI in the anterior teeth experienced a negative impact on social wellbeing, mainly with regard to avoiding smiling or laughing and being concerned about what other people may think or say.

Oral manifestations and treatment of a child with Sjögren's syndrome.

Sjögren's syndrome (SS) is a chronic inflammatory systemic autoimmune disease affecting the exocrine, salivary and lacrimal glands. The condition occurs more often in adults and is rare in childhood. SS should be considered in the differential diagnosis of recurrent parotitis and keratoconjunctivitis sicca. Oral manifestations include early tooth decay and xerostomia. Treatment consists of operative dentistry and saliva management. This paper reports a case of a 10-year-old Brazilian boy with SS, stressing the oral manifestations, treatment conduct, clinical importance and need for an early diagnosis in order to improve the patient's quality of life.

Prevalence and associated factors of traumatic dental injuries in Brazilian schoolchildren.

OBJECTIVES: This study investigated the prevalence of traumatic dental injury (TDI) and associated factors in the permanent incisors of Brazilian schoolchildren. METHODS: A cross-sectional survey was carried out with 1,612 male and female children aged 11 to 14 attending public and private elementary schools in Belo Horizonte, Brazil. A multistage sampling technique was adopted to select the children. Oral examinations were performed by calibrated examiners for the diagnosis of TDI (criteria proposed by Andreasen) and dental caries [Decayed, Missing and Filled Teeth Index (DMFT)]. The Social Vulnerability Index was used for socioeconomic classification. Data analysis involved descriptive statistics and the Poisson regression model. RESULTS: The prevalence of TDI was 17.1%. Falls (43.6%) were the most common cause of TDI, mainly at home (41.8%). Boys were more affected than girls. There was no statistically significant association between TDI and socioeconomic status. The adjusted results revealed that TDI was significantly associated with DMFT [1.11, 95% confidence interval (CI): 1.06 to 1.16] and overjet (1.15, 95% CI: 1.00 to 1.31). CONCLUSIONS: TDI was associated with dental caries and overjet and was not influenced by socioeconomic status.

Effectiveness of procedures for the chemical-mechanical control of dental biofilm in orthodontic patients.

AIM: Assess the effectiveness of chemical-mechanical control associated with orientation and motivation for the control of dental biofilm in orthodontic patients. METHODS AND MATERIALS: Thirty patients between 12 and 21 years of age wearing a fixed orthodontic appliance were divided into three groups. The control group (G1) received orientation regarding oral hygiene. The experimental groups (G2 and G3) received orientation regarding oral hygiene and diet as well as a hygiene kit and mouthwash; the mouthwash given to G2 was a placebo and that given to G3 contained essential oils (Listerine). RESULTS: In the comparison between T0 and T60, vestibular gingivitis was worse in G1 (p<0.05), with no statistically significant differences regarding lingual gingivitis and biofilm. G2 and G3 exhibited a significant improvement in clinical conditions. In the comparison between groups, G3 had undergone a significantly greater improvement than the other groups. CONCLUSION: The use of the commercial mouthwash, together with mechanical oral hygiene, orientation, and motivation, proved to be adequate conduct for the maintenance of oral health in orthodontic patients. CLINICAL SIGNIFICANCE: The present study contributes toward the maintenance of oral health in patients who wear a fixed orthodontic appliance through the prevention of dental biofilm buildup.

Measuring parental-caregiver perceptions of child oral health-related quality of life: psychometric properties of the Brazilian version of the P-CPQ.

The Parental-Caregiver Perceptions Questionnaire (P-CPQ) is an instrument that assesses a parent's or a caregiver's perceptions regarding the impact of children's oral health status on quality of life. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the P-CPQ. Following translation and cross-cultural adaptation, the P-CPQ was tested on 123 parents and caregivers of children between 11 and 14 years of age with dental caries and malocclusions. The parents/caregivers were recruited at dental clinics of the Federal University of Minas Gerais, where their children were receiving dental care. Psychometric properties were assessed through internal consistency, test-retest reliability, construct validity and discriminant validity. The mean P-CPQ score was 13.01 (SD=12.14) for the dental caries group and 16.57 (SD=13.13) for the malocclusion group. Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.84. Test-retest reliability revealed satisfactory reproducibility (ICC=0.83). Construct validity was satisfactory, demonstrating significant correlations between global indicators and the total scale. The P-CPQ score was able to discriminate between different parental/caregiver perceptions of oral conditions in their children (dental caries and malocclusion). The results for the Brazilian version of the P-CPQ confirm that this questionnaire is a reliable and valid instrument to assess parental perceptions on the impact that oral health status has on children's life quality.

Senso de coerência e experiência de cárie dentária em pré-escolares de Belo Horizonte / Sense of coherence and dental caries experience in preschool children from Belo Horizonte city

Objetivo: O objetivo deste estudo foi avaliar a relação entre a saúde bucal de pré-escolares e o Senso de Coerência (SOC) materno. Metodologia: Participaram do estudo 42 mães e suas crianças de 8 meses a 5 anos de idade, matriculados em uma creche pública, em Belo Horizonte, MG. As mães responderam a um questionário retrospectivo sobre o SOC e a higiene bucal de seus filhos. As crianças foram submetidas a um exame físico intra-bucal para o levantamento do índice ceo-d. Os exames foram realizados por um pesquisador calibrado (Kappa = 0,86), em posição joelho-a-joelho, sob luz natural e com o auxílio de um anotador. Os dados foram analisados usando teste qui-quadrado, odds ratio e análise de regressão logística multivariada ao nível de significância de 0,05. Resultados: Não houve diferença estatisticamente significante entre o índice ceo-d, o gênero e a higiene bucal da criança (P>0,05), nem com o SOC materno (P=0,335). A chance de crianças de 4 a 5 anos apresentar ceo-d ≥1 foi 7,5 vezes maior que para as crianças de 8 meses a 3 anos (P=0,019), independentemente das demais variáveis. Conclusão: Conclui-se que a capacidade das mães em se adaptar a um evento estressante não foi associada à experiência de cárie das crianças nesta amostra.

Purpose: The objective of this paper was to evaluate the relationship between mother's Sense of Coherence (SOC) and preschool children's oral health. Methods: The sample consisted of 42 mothers and their children with ages from 8 months to 5 years old, enrolled in a public day care center in Belo Horizonte city, MG. Mothers answered a retrospective questionnaire concerning questions about their SOC and about their children's oral hygiene. Children were subjected to dental clinical examination to collect the dmf-t index. These examinations were carried out by one calibrated researcher (Kappa = 0.86) in knee-to-knee position with natural light. Data were analyzed using qui-square test, adjusted odds ratio, and multivariate logistic regression at the significance level of 0.05. Results: No statistical differences were found between the dmf-t index and child's gender or oral hygiene (P>0.05), nor with mother's SOC (P=0.335). Children aged 4 to 5 years old had 7.5 times more chance to have dmf-t ≥1 then children aged 8 moths to 3 years old (P=0.019) independently from the other variables. Conclusion: In conclusion the mother's stress adaptability was not associated with her child's caries experience in this sample.

Cross-cultural adaptation of the Child Perceptions Questionnaire 11-14 (CPQ11-14) for the Brazilian Portuguese language.

BACKGROUND: Oral-Health-Related Quality of Life (OHRQoL) instruments are being used with increasing frequency in oral health surveys. However, these instruments are not available in all countries or all languages. The availability of cross-culturally valid, multi-lingual versions of instruments is important for epidemiological research. The Child Perceptions Questionnaire 11-14 (CPQ11-14) is an OHRQoL instrument that assesses the impact of oral conditions on the quality of life of children and adolescents. The objective of the current study was to carry out the cross-cultural adaptation of CPQ11-14 for the Brazilian Portuguese language. METHODS: After translation and cross-cultural adaptation, the CPQ 11-14 was tested on 160 11-to-14-year-old children who were clinically and radiographically examined for the presence or absence of dental caries. The children were receiving dental care at the Pediatric Dental and Orthodontic clinics of the Federal University of Minas Gerais, Brazil. To test the quality of the translation, 17 children answered the questionnaire. The internal consistency of the instrument was assessed by Cronbach's Alpha Coefficient and the test-retest reliability by Intraclass Correlation Coefficient (ICC). RESULTS: The mean CPQ11-14 score were 24.5 [standard deviation (SD) 18.27] in the group with caries and 12.89 [SD 10.95] in the group without caries. Median scores were 20 and 10 in the groups with and without caries, respectively (p < 0.001). Significant associations were identified between caries status and all CPQ domains (p < 0.05). Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.86. Test-retest reliability revealed satisfactory reproducibility (ICC = 0.85). The questionnaire proved to be a valid instrument. Construct validity was satisfactory, demonstrating highly significant correlations with global indicators for the total scale and subscales. The CPQ11-14 score was able to discriminate between different oral conditions (groups without and with untreated caries). CONCLUSION: The present study demonstrated that the CPQ11-14 is applicable to children in Brazil. It has satisfactory psychometric properties, but further research is required to evaluate these properties in a population study.

Surgical and orthodontic conduct in the treatment of mesiodens: a case report.

This article reports a clinical case involving an 8-year-old boy with two mesiodentes. The supernumerary teeth caused both a functional alteration (malocclusion) and an esthetic one (interincisal diastema), both of which affected his quality of living. Surgical removal of the supernumerary teeth and orthodontic follow-up was proposed, in agreement with the treatment established in the literature. This treatment produced satisfactory results in terms of both esthetics and functionality.

Seqüelas bucais em crianças submetidas à terapia antineoplásica: causas e definição do papel do cirurgião dentista / Oral sequelae in children submitted to the antineoplastic therapy: causes and definition of the dental surgeon's role

Crianças imunossuprimidas, dentre elas as portadoras de câncer, requerem um acompanhamento odontológico integrado ao atendimento médico. Isso porque são portadoras de inúmeras condições bucais que surgem em decorrência da terapia antineoplástica. O objetivo do trabalho foi fazer uma revisão bibliográfica sobre as alterações bucais mais freqüentes em crianças com câncer e suas possíveis causas, além de definir o papel do cirurgião dentista nesse processo. As seqüelas bucais mais freqüentes decorrentes do câncer em crianças são: xerostomia, mucosite, candidíase, cárie; todas decorrentes da radioterapia e/ou quimioterapia. A presença de um cirurgião dentista na equipe multidisciplinar que atende esses pacientes é de grande auxílio na prevenção e no controle das seqüelas bucais.

A saúde bucal e a educação: o que os educadores em formação conhecem sobre o tema? / Oral health and education: what future professors know about the theme?

É na infância que se iniciam os cuidados de higiene e estruturam-se e estabelecem-se os hábitos e habilidades necessárias à manutenção da saúde. O educador é um agente essencial na construção e transmissão de conhecimentos em saúde bucal, devido ao contato diário e prolongado com as crianças. Mas para educar em saúde, os professores devem ter adquirido conhecimentos, atitudes e habilidades sobre o tema durante seu curso de formação. Assim, o objetivo deste estudo foi avaliar o conhecimento em saúde bucal dos discentes em Pedagogia, comparando alunos de faculdades públicas e privadas. Participaram da pesquisa 248 formandos, sendo 139 de instituições particulares e 109 de públicas. Na composição da amostra, participaram graduandos de todas as escolas de ensino superior da capital de Minas Gerais que ofertavam o curso de Pedagogia. A coleta de dados foi realizada através de um questionário estruturado, validado por um estudo-piloto com aprovação do Comitê de Ética em Pesquisa da UFMG. Um Termo de Consentimento Livre e Esclarecido foi assinado pelos participantes. Os dados foram processados no Programa Epi-Info 6.02, e aplicou-se o teste qui-quadrado com nível de significância de 95%. Os resultados revelaram que houve diferença entre as instituições analisadas (p<0,05), sendo que os alunos de faculdades particulares (56,8%) receberam mais informações sobre saúde bucal em relação aos de faculdades públicas (43,2%). Ambos os grupos destacaram que a família (58,6% dos alunos de faculdades particulares e 41,4% dos de faculdades públicas) e o próprio Cirurgião-dentista (58,1% e 41,9%, respectivamente) eram as principais fontes de tais informações...
