Survival of Adhesive Restorations for Primary Molars: A Systematic Review and Metaanalysis of Clinical Trials.

PURPOSE: The purpose of this study was to assess the scientific evidence regarding the survival and clinical performance of adhesive materials for primary molars, comparing composite resin (CR), conventional glass ionomer cement (GIC), resin-modified glass ionomer (RMGIC), silver-reinforced glass ionomer cement, and compomer. METHODS: Six databases were searched without restrictions regarding language or year of publication. Meta-analysis was conducted; risk ratios (RRs) and 95 percent confidence intervals (95% CI) were calculated. RESULTS: Eleven clinical trials were included. Two studies found that the median survival time (MST) of SRGIC was less than that of GIC and RMGIC (P<0.005), and two studies found that the GIC had a lower MST than both RMGIC and compomer (P<0.05). Meta-analysis for CR, compomer, and RMGIC was conducted. These materials did not differ significantly regarding the number of restorations that survived over 24 months: CR versus RMGIC (RR equals 1.12, 95% CI equals 0.96 to 1.31); CR versus compomer (RR equals 1.04; 95% CI equals 0.96 to 1.13); and compomer versus RMGIC (RR equals 1.03; 95% CI equals 0.84 to 1.27). CONCLUSIONS: Silver-reinforced glass ionomer cement has the worst survival rate among ionomers, and adhesive materials with a resin component have similar survival rates.

Anxiety and worry when coping with cancer treatment: agreement between patient and proxy responses.

PURPOSE: Assess agreement between proxy respondents (caregivers) and children/adolescents related to the impact of cancer on children's/adolescents' health-related quality of life, with respect to anxiety and worry issues. METHODS: A cross-sectional study was conducted among 83 Brazilian children/adolescents, of both genders, diagnosed with cancer, aged 5-18 years and their proxy respondents. Anxiety and worry were assessed through items of the instrument Pediatric Quality of Life Inventory™ Cancer Module Scale. Participants were recruited from the pediatric hematology/oncology centers at two public hospitals. All individuals were receiving medical care. Descriptive statistics were performed as well as a weighted kappa coefficient, Spearman's correlation coefficient, Wilcoxon signed-rank test and Bland-Altman plots. The magnitude of the difference between the mean scores obtained from children/adolescents and that of their proxy respondents was evaluated through effect size. RESULTS: The proxy respondents underestimated the feelings of worry among children (8-12 years) (p < 0.001; effect size 0.71) and overestimated adolescents' (13-18 years) treatment anxiety (p < 0.05; effect size 0.57). The comparison between the three age groups (5-7, 8-12, 13-18 years) showed a tendency for children/adolescents to report increasing feelings of worry as they got older. In the 'treatment anxiety' subscale, there was a tendency for proxy respondents to present higher mean scores, revealing that proxy respondents believed the children's/adolescents' treatment anxiety decreased as they aged. CONCLUSIONS: Discrepancies between the reports of children/adolescents and their proxy respondents were observed. Children's/adolescents' reports should not be ignored nor replaced by proxy reports; both reports should be analyzed together.

Sleep bruxism, awake bruxism and sleep quality among Brazilian dental students: a cross-sectional study.

The aim of the study was to evaluate the association of sleep bruxism, awake bruxism and sleep quality among dental students of the Federal University of Minas Gerais, Belo Horizonte, Brazil. A cross-sectional study was performed including 183 Brazilian dental students aged from 17 to 46 years old. The complete course curriculum consists of 9 semesters. Students enrolled in the first semester, the middle semester and the final semester of the course participated in the survey. The PSQI-BR (the Brazilian version of the Pittsburgh Sleep Questionnaire Index) was used for data collection. The PSQI-BR was distributed during lecture classes. Sleep bruxism and awake bruxism diagnosis was based on self-reported data. Descriptive analysis, Kruskal-Wallis, Mann-Whitney and Poisson regression with robust estimator were the statistical tests used. Sleep bruxism prevalence was 21.5% and awake bruxism prevalence was 36.5%. Sleep duration components were associated with sleep bruxism (PR=1.540; 95% CI: 1.00-2.37) and awake bruxism (PR=1.344; 95% CI: 1,008-1,790). There was an association between awake bruxism and habitual sleep efficiency component (PR=1.323; 95% CI: 1.03-1.70). Sleep disturbance component and awake bruxism were associated (PR=1.533; 95% CI: 1.03-2.27). Poor sleep quality was an important factor among dental students, who reported sleep bruxism as well as among those who presented awake bruxism.

O objetivo deste estudo foi avaliar a associação entre o bruxismo do sono, bruxismo diurno e qualidade do sono entre estudantes de odontologia da Universidade Federal de Minas Gerais, Belo Horizonte, Brasil. Um estudo transversal foi desenvolvido com 183 estudantes de odontologia brasileiros com idade entre 17 e 46 anos. O curriculum completo do curso consiste de 9 semestres. Estudantes matriculados no primeiro semestre, no semestre do meio e no último semestre do curso participaram do estudo. O PSQI-BR (versão brasileira do Pittsburgh Sleep Questionnaire Index) foi utilizado para a coleta dos dados. O PSQI-BR foi distribuído em sala de aula. O diagnóstico de bruxismo do sono e bruxismo diurno foi baseado em auto-relato dos estudantes. Análise descritiva, Kruskal-Wallis, Mann-Whitney e regressão de Poisson com estimativa robusta foram os testes estatísticos utilizados. A prevalência do bruxismo do sono foi de 21,5% e a prevalência do bruxismo diurno foi de 36,5%. O componente duração do sono apresentou associação com bruxismo do sono (PR=1,540; 95%IC: 1,00-2,37) e com bruxismo diurno (PR=1,344; 95%CI: 1,008-1,790). Houve associação entre bruxismo diurno e o componente eficiência habitual do sono (PR=1,323; 95%IC: 1,03-1,70). O componente distúrbio do sono e o bruxismo diurno também apresentaram associação (PR=1,533; 95%IC: 1,03-2,27). A má qualidade do sono foi um fator importante tanto entre os universitários que relataram bruxismo do sono quanto entre os que apresentaram bruxismo diurno.

Influence of traumatic dental injury on quality of life of Brazilian preschool children and their families.

AIM: The aim of this study was to evaluate the impact of traumatic dental injury (TDI) on the oral health-related quality of life (OHRQoL) of Brazilian preschool children and their families. MATERIAL AND METHODS: A cross-sectional study was carried out with 1632 children of both sexes aged 60-71 months in the city of Belo Horizonte, Brazil. Data on OHRQoL were collected using the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS), which was self-administered by parents/caregivers to record their perceptions regarding the oral health of their children. A questionnaire addressing demographic and socio-economic data was also sent to parents/caregivers. Oral examinations of the children were performed by a single, previously calibrated dentist (intraexaminer and interexaminer agreement: kappa ≥ 0.83) for the assessment of the prevalence and type of TDI using the diagnostic criteria proposed by Andreasen et al. [2007]. Bivariate and multiple Poisson regression analyses were performed, with the level of significance set at 5%. RESULTS: The prevalence of negative impact from oral conditions on quality of life was 36.8% and 31.4% for children and families, respectively. TDI was not significantly associated with OHRQoL. Tooth avulsion remained in final multiple models of child OHRQoL [PR = 1.37, 95%CI = 1.02-1.85] and family OHRQoL [PR = 1.55, 95%CI = 1.12-2.14]. Tooth discolouration remained in the final multiple models of family OHRQoL [PR = 1.23, 95%CI = 1.05-1.44]. CONCLUSIONS: The presence of TDI in Brazilian preschool children has no impact on quality of life of the children or their families. However, tooth avulsion is associated with a negative impact on OHRQoL in both groups, and tooth discolouration is associated with a negative impact on family OHRQoL.

Impact of Malocclusion on Oral Health-Related Quality of Life among Brazilian Preschool Children: a Population-Based Study

The purpose of the present study was to evaluate the impact of malocclusion on Oral Health-Related Quality of Life (OHRQoL) of children and their families. A population-based cross-sectional study was carried out in Belo Horizonte, MG, Brazil. A representative sample of 1069 male and female preschoolers aged 60 to 71 months was randomly selected from public and private preschools and daycare centers. Data were collected using the B-ECOHIS. In addition, a questionnaire addressing socioeconomic and demographic data was self-administered by the parents/guardians. The criteria used to diagnose malocclusion were based on Foster and Hamilton (1969), Graboswki et al. (2007) and Oliveira et al. (2008). Descriptive, univariate and multiple Poison logistic regression analyses were carried out. The prevalence of malocclusion was observed in 46.2% of the children and deep overbite was the most prevalent type of malocclusion (19.7%), followed by posterior crossbite (13.1%), accentuated overjet (10.5%), anterior open bite (7.9%) and anterior crossbite (6.7%). The impact of malocclusion on OHRQoL was 32.7% among the children and 27.1% among the families. In Poisson multiple regression model adjusted for socioeconomic status, no significant association was found between malocclusion and OHRQoL of the children (PR=1.09, 95% CI: 0.96-1.24) and their families (PR=1.11, 95% CI: 0.94-1.31). It is concluded that children with malocclusion in this sample did not have a negative impact on their OHRQoL and of their families.

O objetivo do presente estudo foi avaliar o impacto da maloclusão na OHRQoL de crianças e suas famílias. Um estudo transversal de base populacional foi conduzido em Belo Horizonte, Brasil. Uma amostra representativa contendo 1069 crianças dos gêneros masculino e feminino foi randomicamente selecionada, em creches e pré-escolas públicas e privadas. Os dados foram coletados através do questionário B-ECOHIS. Ademais, um questionário contendo dados socioeconômicos e demográficos foi respondido pelos pais/responsáveis das crianças. Os critérios utilizados para o diagnóstico de maloclusão foram baseados nos estudos de Foster e Hamilton (1969), Graboswki et al. (2007) e Oliveira et al. (2008). Análises descritivas, univariadas e regressão logística múltipla de Poisson foram realizadas. A prevalência de maloclusão foi observada em 46,2% das crianças, sendo a mordida profunda o tipo de maloclusão mais frequente (19,7%), seguido de mordida cruzada posterior (13,1%), sobressaliência acentuada (10,5%), mordida aberta anterior (7,9%) e mordida cruzada anterior (6,7%). A prevalência do impacto da maloclusão na OHRQoL foi de 32,7% nas crianças e 27,1% nas famílias. No modelo de regressão múltipla ajustado para o status socioeconômico, não se observou associação significante entre maloclusão e OHRQoL das crianças (PR=1.09, 95% CI: 0,96-1,24) e de suas famílias (PR=1,11, 95% CI: 0,94-1,31). Conclui-se que as crianças que apresentaram maloclusão nesta amostra, não apresentaram impacto negativo na sua OHRQoL e nem de suas famílias.

Oral health-related quality of life among Brazilian preschool children.

OBJECTIVES: The purpose of this study was to evaluate the impact of oral health conditions on oral health-related quality of life (OHRQoL) in population-based sample of Brazilian preschool children. A further aim was to identify the influence of socio-demographic profile and perceptions regarding general health and oral health status on OHRQoL. METHODS: An epidemiological survey was carried out at public and private preschools in the city of Belo Horizonte, Brazil. The sample consisted of 1632 5-year-old male and female preschoolers randomly selected using a multi-stage sampling technique and their parents/caregivers. Oral examinations of the children were performed by a single, previously calibrated examiner for the assessment of dental caries experience, malocclusion, traumatic dental injury and developmental defects of enamel. Caregivers were asked to complete the Brazilian Early Childhood Oral Health Impact Scale (B-ECOHIS) and a form on socio-demographic data. Descriptive, bivariate and adjusted Poisson regression model analyses were carried out. RESULTS: In the child section of the B-ECOHIS, OHRQoL was negatively impacted by decayed, missing and filled teeth [prevalence ratios (PR) = 2.18; 95% CI, 1.88-2.52], position of the child among siblings in the family (PR = 1.20; 95% CI, 1.04-1.39), type of preschool (PR = 1.36; 95% CI, 1.10-1.69), age of parents/caregivers (PR = 1.18; 95% CI, 1.04-1.34), monthly household income (PR = 1.48; 95% CI, 1.18-1.85) and perception of the child's general health status (PR = 1.26; 95% CI, 1.06-1.51). In the family section, the adjusted results demonstrated a negative impact on OHRQoL associated with dental caries experience (PR = 3.40; 95% CI, 2.83-4.08), age of parents/caregivers (PR = 1.16; 95% CI, 1.01-1.33) and monthly household income (PR = 1.41; 95% CI, 1.16-1.72). CONCLUSIONS: Dental caries experience was the only normative criteria with a negative impact on OHRQoL. Families with low income and younger parents reported a greater impact on quality of life. According to parents' perceptions, a poor general health status rating was related to poorer quality of life among the children.

It is concluded that children with malocclusion in this sample did not have a negative impact on their OHRQoL and of their families.

Impact of traumatic dental injury on quality of life among Brazilian preschool children and their families.

PURPOSE: The purpose of this study was to assess the impact of traumatic dental injury (TDI) on the quality of life of preschool children and their families. METHODS: This cross-sectional study was carried out with 388 60- to 71-month-old children. Data on oral health-related quality of life (OHRQoL) were collected using the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). Oral examinations of the children were performed to determine the prevalence of TDI. Data analysis involved the chi-square test and multiple Poisson regression analysis. RESULTS: The prevalence of OHRQoL of the children and their families was approximately 49% and 35%, respectively. The adjusted Poisson regression model revealed that the OHRQoL of the children and their families was significantly related to parents'/caregivers' report of the occurrence of TDI (PR =1.54, 95% confidence interval=1.22-1.93; and PR=1.63, 95% CI=1.21-2.19, respectively). The nonadjusted Poisson regression analysis, the OHRQofL of the children and their families was not related to TDI, as determined by the clinical examination (PR=1.15, 95% CI=0.92-1.42; and PR=1.28, 95% CI=0.95-1.71, respectively). CONCLUSIONS: The families and children who had traumatic dental injury, perceived by the parents/caregivers, had a greater chance of reporting an impact on quality of life.

Fluorose dentária: abordagens terapêuticas para recuperação estética / Dental fluorosis: therapeutic approaches for aesthetic recovery

A fluorose constitui uma alteração do esmalte dentário relacionada ao excesso de ingestão do flúor na época de formação dos dentes. Tais alterações implicam prejuízos na aparência estética e harmonia facial, repercutindo negativamente na autoestima dos indivíduos. Neste contexto, a Odontologia assume papel de destaque: um sorriso com aspecto agradável e atrativo, mostrando dentes em harmonia é o desejo do indivíduo que vive em sociedade. Este artigo apresenta dois casos clínicos de fluorose dentária com diversificadas manifestações clínicas nos quais optou-se por diferentes alternativas terapêuticas. Uma vez diagnosticadas as alterações, e após análise dos casos, foram estabelecidos os planos de tratamento em consonância com a realidade e os anseios das pacientes e dos responsáveis, visando o restabelecimento da estética. No primeiro caso foi realizada a microabrasão com ácido fosfórico 37%. No segundo, adotou-se o clareamento exógeno over night com peróxido de carbamida 10%. Em ambos os casos, as adolescentes mostraram-se satisfeitas com o resultado obtido em função do restabelecimento da estética facial.

Fluorosis is an alteration in dental enamel associated with excess intake of fluoride at the age when teeth are developing. These alterations compromise facial aesthetics and harmony, with negative repercussions on the individual?s self-esteem. Dentistry assumes a prominent role in this context: a nice, attractive smile, teeth in harmony, this is the desire of every individual in society. This article describes two clinical cases of dental fluorosis with different clinical manifestations for which different therapeutic alternatives were chosen. Once the changes were diagnosed, and after considering the cases, treatment plans were established, taking into account the patients? situations and desires and those of their responsible, so as to restore facial aesthetics. In the first case, micro-abrasion with 37% phosphoric acid was performed. In the second case, exogenic overnight bleaching with 10% carbamide peroxide was applied. In both cases, the adolescent patients were happy with the results obtained since their facial aesthetics were restored.

Psychometric properties of the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS).

BACKGROUND: Oral disorders can have a negative impact on the functional, social and psychological wellbeing of young children and their families and cause pain/discomfort for the child. Oral health-related quality of life (OHRQoL) has emerged as an important health outcome in clinical trials and healthcare research. The Early Childhood Oral Health Impact Scale (ECOHIS) is a proxy measure of children's OHRQoL designed to assess the negative impact of oral disorders on the quality of life of preschool children. The objective of this study was to evaluate the psychometric properties of the Brazilian version of the ECOHIS (B-ECOHIS). METHODS: This investigation was carried out in preliminary and field studies. The preliminary study comprised a cross-sectional study carried out in the city of Petropolis, Brazil. A sample of 150 children from two to five years of age was recruited at a public hospital. In the field study, an epidemiological survey was carried out in public and private preschools of Belo Horizonte, Brazil. The B-ECOHIS was answered by 1643 parents/caregivers of five-year-old male and female preschool children. In both phases, oral examinations were performed by a single previously calibrated dentist. Reliability was determined through test-retest reliability and internal consistency. Validity was determined through convergent and discriminant validities. The correlation between the scores obtained on the child and family impact sections was assessed. RESULTS: In the preliminary (P) and field (F) study, test-retest reliability correlation values were 0.98 and 0.99 for the child impact section and 0.97 and 0.99 for the family impact section, respectively. The B-ECOHIS demonstrated internal consistency: child impact section (P: α = 0.74; F: α = 0.80) and family impact section (P: α = 0.59; F: α = 0.76). The correlation between the scores obtained on the child and family impact sections was statistically significant (P: rs = 0.54; F: rs = 0.62; p ≤ 0.001). In both phases of the study, B-ECOHIS scores were significantly associated with the decayed, missing and filled teeth index, decayed teeth and discolored upper anterior teeth (p < 0.05). CONCLUSION: The B-ECOHIS proved reliable and valid for assessing the negative impact of oral disorders on the quality of life of preschool children.

Aesthetic management of tooth discolouration: conservative treatment for a patient with undifferentiated nasopharyngeal carcinoma / Abordagem estética da descoloração dentária: tratamento conservador de um paciente com carcinoma nasofaríngeo indiferenciado

PURPOSE: Dental aesthetics has considerable impact in our beauty-conscious society. The darkening of the anterior teeth causes concern for adolescents due to the compromised physical appearance. This article presents a clinical case of tooth staining in an individual who had undergone radiotherapy/chemotherapy for an undifferentiated nasopharyngeal carcinoma. CASE DESCRIPTION: A 14-year-old boy presented to the dental clinic complaining of pain and staining of the maxillary and mandibular incisors, canines and premolars after having undergone radiotherapy/chemotherapy and stated his desire to remove the dark stains from the surface of the teeth due to his compromised oral aesthetics. Tooth whitening was performed with hydrogen peroxide, followed by micro-abrasion. At a two-year follow-up visit, clinical success was observed and the child was very satisfied. CONCLUSION: The adoption of such methods provided efficient alternatives for the re-establishment of a healthy smile, thereby returning pleasing facial aesthetics to the patient. The minimization of distress is nearly always the focus of clinical efforts at promoting psychological health in cancer survivors.

OBJETIVO: Atualmente, a estética dentária tem um impacto considerável na sociedade. O escurecimento dos dentes anteriores causa preocupação para os adolescentes, devido à aparência física comprometida. Este artigo apresenta um caso clínico de descoloração dentária em um indivíduo submetido a radioterapia/quimioterapia para tratamento de um carcinoma indiferenciado de nasofaringe. DESCRIÇÃO DO CASO: Um adolescente do gênero masculino, de 14 anos de idade, apresentou-se à clínica odontológica com queixa de dor e pigmentação dos incisivos superiores e inferiores, caninos e pré-molares após ter sido submetido a radioterapia/quimioterapia, declarando seu desejo de remover as manchas escuras na superfície do dentes comprometidos, devido à sua estética bucal. Foi realizado um clareamento dentário com peróxido de hidrogênio, seguido por micro-abrasão. Em um período de dois anos de seguimento, foi observado o sucesso clínico e a satisfação da criança. CONCLUSÃO: A adoção de tais métodos proporciona alternativas eficientes para o restabelecimento de um sorriso saudável, resgatando assim uma imagem facial agradável para o paciente. A minimização do sofrimento é geralmente o foco dos esforços clínicos visando a promoção da saúde psicológica em pacientes que sobreviveram ao câncer.

Academic trajectories of dental researchers receiving CNPq's productivity grants.

The present study analyzed the profile of dental researchers receiving grants related to their productivity in research from the Brazilian National Research and Development Council (CNPq). Data collection was carried out in March 2008, using the Brazilian database for curriculum vitae (Lattes Format). There were 144 researchers registered in the database and linked to 25 institutions. These researchers published a total of 12,997 full-text articles, 6,927 of which were published in the last 5 years. Category 1 grant holders (n=77) were responsible for 53.5% of this production; Category 2 grant holders (n=65) were responsible for 45.1%; Senior grant holders (n=2) were responsible for 1.4%. Regarding institutional affiliation, 90.3% of the research grants holders develop activities at public institutions and 9.7% develop activities in private institutions. Furthermore, 84.0% of the researchers are linked to institutions located in the southeast region of Brazil and 75.0% of the researchers perform their activities in the state of São Paulo. This study performed a mapping of the distribution of CNPq researchers, revealing a concentration in the southeast region of the country, especially in the state of São Paulo. The findings of the present study also demonstrate the important contribution of grant holders to the scientific production in dentistry in Brazil.

O esclarecimento do responsável com relação ao tratamento odontológico da criança na Clínica de Odontopediatria da FO-UFMG / What parents understand of their children’s dental treatment in the Pediatric Dentistry Clinic of UFMG

O presente estudo teve por objetivo avaliar o esclarecimento prestado a 60 responsáveis com relação ao tratamento odontológico de suas crianças, com idades entre 4 e 12 anos, de ambos os sexos, que foram atendidas na clínica de Odontopediatria da Faculdade de Odontologia da UFMG. O instrumento utilizado foi um formulário, adaptado de Colares et al. (1998), aplicado aos responsáveis sob a forma de entrevista, constando de questões referentes ao esclarecimento quanto ao tratamento realizado. Foram coletados dados das crianças, dos responsáveis e da condição econômica da família. Otermo de consentimento livre e esclarecido foi aplicado em toda a amostra. Para análise estatística adotou-se os testes qui-quadrado e exato de Fisher com 5% de significância através do programa SPSS 10.0. De acordo com os resultados, foi possível averiguar que 61,7% dos responsáveis não souberam relatar corretamente o tratamento que estava sendo realizado na criança. Apesar disso, 78,3% julgaram haver participado na decisão de tratamento e 95,0% consideraram os alunos de odontologia acessíveis a questionamentos. Os resultados mostraram que não houve diferença estatisticamente significativa entre o esclarecimento e a classificação econômica da família (p = 0,284) e o relato dos responsáveis quantoao recebimento de informações sobre o tratamento (Fisher = 0,015). Desta forma, foi possível concluir que a maioriados responsáveis demonstrou não estar devidamente esclarecida quanto ao tratamento odontológico realizado em suas crianças, sugerindo que os mesmos não exerceram de forma satisfatória o direito à autonomia.

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.

Möbius syndrome: a case with oral involvement.

Seven-year follow-up of esthetic alternative for the restoration of peg-shaped incisors: a case study of identical twins.

Alterations in tooth shape and size are related to impaired esthetic appearance and facial harmony and can have a negative effect on a patient's self-esteem. Many alternatives for treating peg-shaped teeth are described in the literature. This article presents two clinical cases involving peg-shaped lateral incisors that were transformed with composite resins, addressing aspects related to treatment alternatives and facial esthetics. At a seven-year recall visit, the composite resins were problem-free and the patients remained very happy with the treatment outcome. Composite resin appears to be an adequate alternative to direct treatment options for restoring peg-shaped incisors.

Academic trajectories of dental researchers receiving CNPq's productivity grants

The present study analyzed the profile of dental researchers receiving grants related to their productivity in research from the Brazilian National Research and Development Council (CNPq). Data collection was carried out in March 2008, using the Brazilian database for curriculum vitae (Lattes Format). There were 144 researchers registered in the database and linked to 25 institutions. These researchers published a total of 12,997 full-text articles, 6,927 of which were published in the last 5 years. Category 1 grant holders (n=77) were responsible for 53.5 percent of this production; Category 2 grant holders (n=65) were responsible for 45.1 percent; Senior grant holders (n=2) were responsible for 1.4 percent. Regarding institutional affiliation, 90.3 percent of the research grants holders develop activities at public institutions and 9.7 percent develop activities in private institutions. Furthermore, 84.0 percent of the researchers are linked to institutions located in the southeast region of Brazil and 75.0 percent of the researchers perform their activities in the state of São Paulo. This study performed a mapping of the distribution of CNPq researchers, revealing a concentration in the southeast region of the country, especially in the state of São Paulo. The findings of the present study also demonstrate the important contribution of grant holders to the scientific production in dentistry in Brazil.
