Objetivos: Avaliar a efetividade entre diferentes intervalos de retorno na incidência de cárie em pré-escolares que apresentaram risco baixo de cárie dentária, e também, avaliar o nível de ansiedade e qualidade de vida relacionada à saúde bucal (QVRSB) das crianças de acordo com cada intervalo empregado. Métodos: A amostra foi composta por 224 crianças de escolas públicas, com idade entre 3 a 5 anos, de ambos os sexos, com baixo risco de cárie. As crianças foram alocadas aleatoriamente em dois grupos de estudo, de acordo com dois intervalos de retorno, sendo: Grupo 1 (G1) - exame clínico bucal + escovação dental profissional + orientação de higiene bucal e dieta no intervalo de retorno de 12 meses e Grupo 2 (G2) - exame clínico bucal + escovação dental profissional + orientação de higiene bucal e dieta no retorno de 18 meses. O exame clínico bucal foi realizado por um examinador previamente calibrado e cego aos grupos de estudo e aos desfechos secundários. O exame clínico bucal incluiu o índice de sangramento gengival de Löe, índice de biofilme dentário de Greene e Vermillion simplificado, detecção de lesões de cárie e da sua atividade de acordo com o ICDAS (International Caries Detection and Asessment System). O nível de ansiedade e a QVRSB foram avaliados pela Escala de Imagem Facial e pelo B-ECOHIS, respectivamente, por um dentista externo. O dentista externo também realizou as orientações sobre higiene bucal e dieta, e a avaliação das condições socioeconômicas. Os testes qui-quadrado e o de Mann-Whitney foram utilizados para avaliar a diferença na proporção de crianças e na média de dentes com novas lesões de cárie entre G1 e G2, respectivamente. Análises de Regressão de Poisson com variância robusta foram realizadas para avaliar o desfecho primário de incidência de cárie dentária considerando dois pontos de corte durante os retornos: 1) incidência de lesões de cárie não cavitadas ativas; 2) incidência de lesões cavitadas em dentina. Resultados: Foi observado uma diferença estatisticamente significativa unicamente para a incidência de lesões iniciais de cárie ativas entre os grupos (p=0,012). Na consulta de retorno crianças que pertenciam ao G2 tiveram maior risco de desenvolver lesões iniciais ativas em comparação ao G1 (RR= 2,37; p=0,047) e também aquelas com um maior índice de placa bacteriana (RR=3,14; p<0,001). Crianças que moram em família não nuclear (RR=2,56; p=0,007), com mais de um irmão (RR=2,53; p=0,037), e que utilizavam dentifrício sem flúor ou em baixa concentração no baseline (RR=3,91; p=0,012), tiveram maior risco de desenvolver lesões de cárie iniciais ativas. Crianças com maior número de dentes com lesões iniciais ativas nos retornos tiveram maior risco de desenvolver lesões de cárie cavitadas em dentina (RR=1,62; p=0,001). Conclusões: O intervalo de retorno de 12 meses é mais efetivo na incidência de cárie não cavitada ativa em pré-escolares de baixo risco de cárie, sendo que estas lesões são um fator preditivo para a progressão de lesões de cárie cavitadas em dentina. Porém não há diferenças na escolha do intervalo de retorno para lesões cavitadas em dentina, níveis de ansiedade e QVRSB. / Objectives: To assess the effectiveness between different recall intervals on dental caries incidence in preschool children with low risk of caries, as well as, the level of anxiety and oral health-related quality of life (OHRQoL) of children according to each interval applied. Methods: The sample consisted of 224 children from public schools, aged between 3 to 5 years, of both genders, with low risk of caries. The children were randomly allocated into two study groups according to two recall intervals being: Group 1 (G1) - oral clinical examination + professional dental brushing + orientation for oral health and diet on the recall of 12 months and, Group 2 (G2) - oral clinical examination + professional dental brushing + orientation for oral health and diet on the recall of 18 months. A previously calibrated and blinded examiner for study groups and secondary outcomes performed the oral clinical examinations. The examinations consisted of the Löe gingival bleeding index, Greene and Vermillion simplified dental biofilm index, detection of caries lesions and their activity according to the International Caries Detection and Assessment System (ICDAS). An external dentist assessed the anxiety levels and OHRQoL scores by the Facial Imaging Scale and B-ECOHIS, respectively. The external dentist also performed dental hygiene and diet orientations, and the assessment of socioeconomic conditions. The chi-square and Mann-Whitney tests were used to assess the difference in the proportion of children and mean of teeth with new caries lesions between G1 and G2, respectively. Poisson Regression analyses with robust variance were performed to evaluate dental caries incidence considering two cutoff points during the returns: 1) incidence of active non-cavitated caries lesions; 2) incidence of cavitated lesions in dentin. Results: A statistically significant difference was observed only for the incidence of initial active caries lesions between the groups (p=0.012). In the recall interval children who remain in the G2 group and who had a higher plaque index, had a higher risk of developing active lesions (RR=2.37; p=0.047 and RR=3.14; p<0.001, respectively) compared to the G1 group. Children living in non-nuclear families (RR=2.56; p=0.007), with more than one sibling (RR=2.53; p=0.037), and who used fluoride-free or with low concentration in the baseline (RR=3.91; p=0.012) had a higher risk of developing active initial caries lesions. Children with higher number of initial active lesions in the recalls had a higher risk of developing caries lesions cavitated in dentin (RR=1.62; p=0.001). Conclusions: The 12-months recall interval is more effective on the incidence of active non-cavitated caries in preschoolers with low risk caries, which is a predictive factor for the progression of cavitated carious lesions in dentin. There are no differences in the choice of the recall interval for cavitated lesions in dentin, anxiety levels and OHRQoL.

Magister Chirurgiae Dentium (MChD) / Oral Squamous Cell Carcinoma (OSCC) patients suffer from the terrible consequences of the disease and its treatment modalities, and as a result, their Quality of Life (QoL) and Oral Health-related Quality of Life (OHRQoL) is badly affected, especially due to functional limitation, physical disability and psychological disability that they encounter before, during and after treatment. There is a need for more research on OHRQoL of OSCC patients at various treatment intervals. The present study focused on investigating OHRQoL of OSCC patients at the post-treatment phase.

Purpose: The purpose of this study was to study the association between Silver Diamine Fluoride (SDF) and Oral Health-Related Quality of Life as assessed by “The Early Childhood Oral Health Impact Scale” questionnaire. Methods: Parents of healthy children (ASA I and II) ages 1-5 with early childhood caries with reversible pulpitis who had application of SDF filled out a questionnaire at baseline and again after one month. The questionnaire was designed to evaluate the child’s behavior, physical abilities, pain, temperament, and how well the child gets along with others. Results: Wilcoxon Signed Rank Test was used to determine if responses to various ECOHIS items and the total scores were different between the two time points. Conclusion: Children with dental caries who had application of SDF reported less dental pain, less eating problems, higher quality of sleep and overall higher quality of life at one-month follow up compared with the baseline.

INTRODUCTION : Pour mieux comprendre l’impact des différentes conditions bucco-dentaires sur les enfants, de nombreux outils permettant de mesurer la qualité de vie liée à la santé bucco-dentaire (QVLSB) ont été développés. Cependant, il n’existe aucun outil en français pour les enfants québécois. OBJECTIF : Le but de cette étude était d’effectuer la traduction et l’adaptation culturelle de la version abrégée du questionnaire Child Oral Health Impact Profile (COHIP-19) en français et d’évaluer certaines propriétés psychométriques. MÉTHODOLOGIE : La traduction et l’adaptation culturelle de la version originale du COHIP-19 en français ont été effectuées selon la technique inversée parallèle avec un comité de traduction. La version traduite a été complétée à deux reprises à 59 enfants québécois francophones âgés de 8 à 15 ans avec un délai de passation allant de 1 à 3 semaines. Les scores du questionnaire ont été comparés selon le sexe, l’âge et le statut de traitement orthodontique. La validité de convergence, la cohérence interne et la stabilité temporelle sont les propriétés psychométriques du questionnaire qui ont été évaluées. RÉSULTATS : Aucune différence significative n’a été trouvée entre les scores du questionnaire en fonction du sexe, l’âge ou le statut de traitement orthodontique. L’auto-perception de la santé bucco-dentaire était significativement corrélée avec le score total du questionnaire (rs = 0,371; P = 0,004), indiquant que l’instrument possède une bonne validité de convergence. Le version traduite a également révélé une cohérence interne acceptable (alpha de Cronbach = 0,67) et une excellente fiabilité test-retest (ICC = 0,99; P < 0,0001). CONCLUSION : Les données recueillies ont montré que la version traduite du COHIP-19 possède des propriétés psychométriques suffisantes. Toutefois, il faudrait effectuer des études de validation sur un échantillon plus grand et représentatif, ainsi que dans un contexte hors pandémie. / BACKGROUND : For a better understanding of the burden of oral health disorders on children, many different tools are available to measure oral health-related quality of life (OHRQoL). However, none of these tools are available in French for the children of Quebec. AIM : The aim of this study was to translate and culturally adapt the short form of the Child Oral Health Impact Profile (COHIP-19) to French and to assess some of its psychometric properties. METHODS : The original English COHIP-19 was translated into French using a forward and backward translation procedure using a translation committee. The translated version was filled out twice by 59 children between the ages of 8 and 15 with a completion time ranging from 1 to 3 weeks. Questionnaire scores were compared by gender, age, and orthodontic treatment status. The convergent validity, the internal consistency and testretest reliability were the psychometric properties used in the evaluation of this questionnaire. RESULTS : No significant difference was found between questionnaire scores with respect to gender, age and orthodontic treatment status. The self-perceived oral health rating was significantly correlated with the translated version’s total score (rs = 0,37; P = 0,004) indicating that the instrument had sufficient convergent validity. The translated version also revealed good internal consistency (Cronbach’s alpha = 0,67) and an excellent test-retest reliability (ICC = 0,99; P < 0,0001). CONCLUSION : The collected data showed that the French Canadian translation of the COHIP-19 possesses acceptable psychometric properties. However, a validation study should be performed on a larger and more representative sample, as well as in a nonpandemic context.
