RESUMO

PURPOSE: To evaluate the association among dimensions of the hard palate according to the sexes, skin color, and periods of the mixed dentition and present reference parameters of normality for this stage of development. METHODS: This cross-sectional study evaluated a representative sample of children between the ages of 7 and 13 years in Santa Maria, southern Brazil. The outcomes of the study were the dimensions of the palate: width measurements and depth. Sociodemographic characteristics and related oral measures were also assessed. Adjusted linear regression model were used to evaluate the effect of the predictor's variables on the dimensions of the hard palate in millimeters. The reference standards for the hard palate normality were presented in mean, standard deviation, and 95% confidence interval. RESULTS: A total of 569 children were evaluated. The hard palate dimensions were larger in the male sex and smaller in the first transitional period of mixed dentition. Skin color had an influence on the hard palate width at the level of the premolars, and the width measurements were smaller in white individuals. Posterior cross bite, Angle Class II and III malocclusions and non-nutritional sucking habits caused reduction in the hard palate width measurements. CONCLUSION: Different dimensions of the hard palate are influenced by demographic variables such as sex, skin color, and mixed dentition period. Children of the female sex, white-skinned and in the first transition period of mixed dentition had smaller dimensions of the hard palate. Establishing normality reference standards in measurements of the palates guides the clinical practice.

RESUMO

PURPOSE: To evaluate the agreement among instruments of the quantitative evaluation of hard palate. METHODS: This cross-sectional study was performed with a sample of 30 children aged 6 to 11 from Santa Maria, Southern Brazil. The instruments for palate measurements evaluated were: digital caliper, used directly in the oral cavity and in plaster casts, Korkhaus tridimensional bow, used directly in the oral cavity and in plaster casts, and Dolphin Imaging Software used for measurements in cone-beam computed tomography (CBCT). The agreement among different instruments was evaluated using the Intraclass Correlation Coefficient (ICC). RESULTS: The means of all transversal dimensions obtained by cone-beam computed tomography were lower than those of the other instruments - the agreement values in the width between the canines and in the width between the first molars were lower when comparing the cone-beam computed tomography and the other instruments. In the width between the first and second premolars, all comparisons showed acceptable agreement values. Good concordance values were obtained when comparing the palate depth at the second premolar region when using a bow divider inside the oral cavity and in the cast. CONCLUSION: Most instruments presented satisfactory agreement in the measurements related to the transverse plane of the hard palate. However, when the vertical plane was evaluated, only the bow divider applied to both cast and oral cavity presented ideal agreement.

RESUMO

The objective was assess the influence of untreated caries and socioeconomic status (SES) on school dropout among adolescents. A six-year cohort study was conducted with random sample of adolescents (12 years-old) who had been evaluated initially in 2012 from Santa Maria, Brazil. Sex, socioeconomic status (mother's education and household income), and untreated caries were collected at the baseline. The outcome variable was collected at the follow-up through self-report and was divided into three categories: adolescents who only studied, who studied and employed, and who school dropouts. A multinomial regression model was performed to assess the influence of oral disease and SES on school leaving, through relative risk ratio (RRR) and 95% confidence interval (95% CI). From of 1,134 adolescents evaluated at the baseline, 768 participants with a mean age of 17.5 years were re-evaluated at follow-up (67.8% response rate). Male (RRR: 2.31; 95%CI: 1.19-4.48) and adolescents with untreated caries at the baseline had an increment in school-leaving (RRR: 2.26; 95%CI: 1.12-4.56). Mothers with low education (RRR: 2.24; 95%CI: 1.09-4.61) had a higher probability of having children who leave school. Untreated caries and low SES in early adolescence can influence the tendency to school dropouts.

RESUMO

Background: Machine learning (ML) has emerged as a branch of artificial intelligence dealing with the analysis of large amounts of data. The applications of ML algorithms have also expanded to health care, including dentistry. Recent advances in this field point to future improvements in diagnostic techniques and the prognosis of various diseases of the teeth and other maxillofacial structures. Aim: The aim of this literature review is to describe the basis for ML being applied to different dental sub-fields in recent years, to identify typical algorithms used in the studies, and to summarize the scope and challenges of using these techniques in dental clinical practice. Relevance for Patients: The proficiency of emerging technologies that have begun to show encouraging results in the diagnosis and prognosis of oral diseases can improve the precision in the selection of treatment for patients. It is necessary to understand the challenges associated with using these tools to effectively use them in dental services and ensure a higher quality of care for patients.

RESUMO

BACKGROUND: Malocclusions are highly prevalent in childhood and adolescence, being considered a public health problem worldwide, in addition to be considered an important predictor in the tongue position and speech disorders. OBJECTIVE: Evaluate the association of malocclusions with tongue position and speech distortion in mixed-dentition schoolchildren from the south of Brazil. METHODOLOGY: This cross-sectional study was performed using a database of an epidemiological survey realized in the southern of Brazil, in 2015, for evaluating the dental and myofunctional condition of the mixed-dentition from 7-13 years' schoolchildren. The outcome variables were tongue position and speech distortion, evaluated by a trained and calibrated examiner. Characteristics regarding sociodemographic and oral health measures (Angle's classification of the malocclusion, overjet, overbite, posterior crossbite and respiratory mode) were also assessed. Poisson regression models with adjusted robust variance were used to evaluate the association among predictors variables in the outcomes. Results are presented as prevalence ratio (PR) and 95% confidence interval (95% CI). RESULTS: A total of 547 children were evaluated. Schoolchildren who presented anterior open bite (PR 2.36 95%CI 1.59-3.49) and having oral/oral-nasal breathing (RP 2.51 95%CI 1.70-3.71) are more likely to have altered position of the tongue. Both deep bite and being male represent protection factors for the abnormal tongue position. Regarding speech distortion, deep overbite presents a protective relationship to speech distortion (PR 0.41; 95%CI 0.24-0.71), whereas schoolchildren with posterior crossbite were more likely to present this problem (PR 1.77; 95%CI 1.09-2.88). CONCLUSION: Anterior open bite and posterior crossbite were the malocclusions related to speech distortion and/or altered tongue position. Oral/oral-nasal breathing was also related to myofunctional changes. Deep bite malocclusion was a protective factor for both speech problems and altered tongue position when compared to a normal overbite.

RESUMO

Most of the Brazilian population is covered by the Family Health Strategy (FHS), however no longitudinal study has assessed the impact of the FHS on child oral health-related quality of life (OHRQoL). The objective of the study was to evaluate the longitudinal impact of the FHS on the OHRQoL. This study followed up 459 children aged 2 to 5 years for 2 years. OHRQoL was assessed by the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS) at baseline (April to November 2016) and follow-up (April to December 2018). Children's parents answered a questionnaire regarding sociodemographic information, FHS service, and dental service. Participants were clinically examined for dental caries. Multilevel Poisson regression was used to assess the associations between FHS variables at baseline and overall/domain-specific of the ECOHIS scores over time. A total of 365 children were reassessed for OHRQoL (follow-up rate: 79.5%). The absence of FHS coverage from the child's first year of age was associated with higher scores in the family function domain [rate ratio (RR) = 2.42; 95% confidence interval (CI) 1.28-4.58)]. Home visits by the FHS team members were associated with higher psychological domain scores (RR = 1.60; 95%CI 1.01-2.57). Children not covered by the FHS since the first year of age reported worse OHRQoL over time. This fact highlights the importance of an integrated health approach to promote children's health.

RESUMO

This study aimed to verify, through a longitudinal follow-up, the pre-, peri- and postnatal factors associated with the eruption of deciduous teeth. The study was nested in a Birth Cohort Study conducted in Pelotas, a Southern Brazilian city. Mothers were followed prenatally and their children were followed-up perinatally, at 3 and 12 months of age. The outcome was the number of teeth at 12 months, and exploratory variables included maternal habits and characteristics, anthropometric measures of children and mothers, and socioeconomic and demographic information. Data were collected through interviews with the mother and children's clinical exam. Poisson regression models were used for the analysis. Participants included 4,014 children with a mean number of erupted teeth at 12 months of 5.50. After adjustments, a lower mean number of teeth was observed in children from non-white mothers, early preterm children, and shorter children at birth and at 12 months. A higher number of teeth was observed for mothers with excessive weight gain during pregnancy, mothers who smoked during pregnancy, weightier children at birth and at 12 months, and for children with larger heads at birth and at 12 months. Our findings suggest that maternal and children characteristics influenced primary tooth eruption.

RESUMO

Background: Happiness is a subjective construct. Validation studies to confirm validity and reliability of happiness measures are needed to verify its applicability in research and clinical fields. Aim: The aim of this study was to test the psychometric properties and longitudinal measurement invariance (MI) of the subjective happiness scale (SHS) in adolescents. Methods: A longitudinal study was conducted with a random sample of 1134 12-year-old adolescents from Santa Maria, a southern city in Brazil, starting in 2012. Two years later, 746 adolescents were reassessed, with an average age of 14. The Brazilian version of the SHS, which is composed of 4 items, was administered by a face-to-face interview. Reliability (Cronbach's alpha), reproducibility (intraclass correlation coefficient - ICC), discriminant validity, confirmatory factor analysis (CFA), convergent validity, and MI were performed through the multigroup CFA. Socioeconomic, clinical, and subjective variables were also collected through clinical examinations and structured questionnaires by calibrated and trained dentists. Results: Cronbach's alpha and ICC results were moderate (0.51 and 0.70, respectively). The scale was able to discriminate subjective happiness between different oral health groups and socioeconomic status. The CFA revealed a good fit model in both collections, confirming the validity of the scale. Convergent validity was satisfactory, demonstrating that the SHS is similar in theoretical concepts with a subjective scale. Moreover, MI showed a goodness-of-fit statistics across time points. Conclusion: The Brazilian version of SHS showed adequate validation properties and longitudinal measurement among adolescents. Relevance for patients: These findings are important for studies that evaluate happiness and oral disorders, through cross-section and longitudinal studies.

RESUMO

OBJECTIVE: To assess the influence of early childhood malocclusion on oral health-related quality of life (OHRQoL). METHODS: 7-year cohort study involving 639 preschoolers (1 to 5 years) who had been evaluated initially with a survey conduced in 2010. Children completed the Brazilian version of the Child Perception Questionnaire (CPQ8-10) to assess OHRQoL during the follow-up period. Exploratory variables were collected at baseline, including the presence and severity of malocclusion (overjet and lip coverage). Socioeconomic characteristics, oral health behavior, and patterns of dental attendance were also investigated. A multilevel Poisson regression model was used to fit the association between malocclusion and OHRQoL. With this approach, incidence rate ratio (IRR) and 95% confidence intervals (95% CI) were calculated. RESULTS: A total of 449 children were re-evaluated (follow-up rate, 70.3%). The prevalence of accentuated overjet and inadequate lip coverage was 13.5% and 11.9%, respectively. The mean (±SD) CPQ8-10 score was 10.57±10.32. The presence of inadequate lip coverage was associated with higher overall mean CPQ8-10 scores (IRR 1.51; 95% CI 1.29-1.77), and social well-being, emotional well-being, and functional limitation domains. Children with accentuated overjet (>3mm) also demonstrated higher overall scores on the CPQ8-10 than their normal counterparts. The presence of this condition also influenced the oral symptom (IRR 1.29; 95% CI 1.08-1.53) and emotional well-being (IRR 1.30; 95% CI 1.02-1.66) domains. CONCLUSION: Results of the present study suggest that early childhood malocclusion is a risk factor for low OHRQoL in future.

RESUMO

Abstract The objective was assess the influence of untreated caries and socioeconomic status (SES) on school dropout among adolescents. A six-year cohort study was conducted with random sample of adolescents (12 years-old) who had been evaluated initially in 2012 from Santa Maria, Brazil. Sex, socioeconomic status (mother's education and household income), and untreated caries were collected at the baseline. The outcome variable was collected at the follow-up through self-report and was divided into three categories: adolescents who only studied, who studied and employed, and who school dropouts. A multinomial regression model was performed to assess the influence of oral disease and SES on school leaving, through relative risk ratio (RRR) and 95% confidence interval (95% CI). From of 1,134 adolescents evaluated at the baseline, 768 participants with a mean age of 17.5 years were re-evaluated at follow-up (67.8% response rate). Male (RRR: 2.31; 95%CI: 1.19-4.48) and adolescents with untreated caries at the baseline had an increment in school-leaving (RRR: 2.26; 95%CI: 1.12-4.56). Mothers with low education (RRR: 2.24; 95%CI: 1.09-4.61) had a higher probability of having children who leave school. Untreated caries and low SES in early adolescence can influence the tendency to school dropouts.


Resumo O objetivo foi avaliar a influência da cárie dentária não tratada e do status socioeconômico (SES) sobre o abandono escolar dos adolescentes. Foi realizado um estudo de coorte de seis anos de acompanhamento com uma amostra aleatória de adolescentes (12 anos de idade) avaliados inicialmente em 2012 em Santa Maria, Brasil. Sexo, status socioeconômico (educação da mãe e renda familiar) e cárie não tratada foram coletados no início do estudo. A variável de desfecho foi coletada no acompanhamento por meio do autorrelato e foi dividida em três categorias: adolescentes que apenas estudavam, aqueles que estudavam e trabalhavam e quem tinha abandonado a escola. Um modelo de regressão multinomial foi realizado para avaliar a influência da doença bucal e do SES sobre o abandono escolar, por meio da razão de risco relativo (RRR) e intervalo de confiança de 95% (IC95%). Dos 1.134 adolescentes avaliados no início do estudo, 768 participantes com idade média de 17,5 anos foram reavaliados no acompanhamento (taxa de resposta de 67,8%). Meninos (RRR: 2,31; IC 95%: 1,19- 4,48) e adolescentes com cárie não tratada no início do estudo tiveram um incremento no abandono escolar (RRR: 2,26; IC 95%: 1,12-4,56). Mães com baixa escolaridade (RRR: 2,24; IC95%: 1,09-4,61) tiveram maior probabilidade de ter filhos que abandonaram a escola. Cárie dentária não tratada e baixo SES no início da adolescência pode influenciar a tendência de evasão escolar.

RESUMO

AIM: To investigate the agreement between the 2018 EFP/AAP periodontitis case classification and the 2012 CDC/AAP criteria. MATERIALS AND METHODS: This cross-sectional study assessed a population-based sample from a rural area in southern Brazil. A complete periodontal examination was performed at six sites/tooth. The periodontitis case definition was estimated and compared according to the 2018 EFP/AAP classification and the 2012 CDC/AAP criteria (reference). Diagnostic tests included sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and area under ROC curve (AUC). RESULTS: Five hundred and eighty-eight subjects with ≥6 teeth each were included. Based on the 2018 EFP/AAP classification, 71.1% of the subjects were classified as stage III/IV showing 100% agreement with 2012 CDC/AAP criteria for the severe category. For the moderate and severe classification, the 2018 EFP/AAP SN was 99.8% and 100%, SP 13.6% and 43.6%, PPV 83.4% and 47.4%, and NPV 93.7% and 100%, respectively. The AUC was 0.9059 (95% CI = 0.879-0.933) and the optimal cut-off based on the curve was stage III. CONCLUSIONS: The 2018 EFP/AAP periodontitis case classification showed high agreement with the 2012 CDC/AAP criteria in a rural sample with high periodontitis occurrence.

RESUMO

The development of dental caries in first permanent molars has been extensively investigated. However, studies are inconclusive in determining the influence of contextual and individual factors on dental caries incidence in this group of teeth. The aim of this study was to evaluate the influence of contextual and individual factors on dental caries incidence in first permanent molars. This 7-year cohort study was conducted with children (1-5 years of age) who had been assessed initially in a survey performed in 2010. Dental caries was assessed at the baseline through the International Caries Detection and Assessment System (ICDAS). Contextual and individual variables were collected at baseline and included the presence of cultural community centers in the neighborhood as well as demographic, socioeconomic, psychosocial, and biological characteristics. A multilevel Poisson regression model was used to investigate the influence of individual and contextual characteristics on dental caries incidence in first permanent molars (relative risk [RR] and 95% confidence interval [CI]). Of the 639 children examined at baseline, a total of 449 were reassessed after 7 years (70.3% retention rate). Children who lived in neighborhoods with cultural community centers had a lower risk of dental caries in first permanent molars at the follow-up (RR 0.78; 95% CI 0.62-0.99). Children from families with a low income (RR 1.34; 95% CI 1.03-1.76) and poor parental perception of children's oral health (RR 1.56; 95% CI 1.18-2.06) were associated with a higher risk of dental caries in first molars. In conclusion, individual and contextual determinants showed an important role in the incidence of caries in first permanent molars.

RESUMO

BACKGROUND: The impact of the COVID-19 pandemic on behavioural and psychosocial aspects related to oral health is unknown. AIM: This study evaluated the psychosocial and behavioural changes related to oral health in adolescents immediately before and during the pandemic period of COVID-19, enabling a longitudinal assessment of the perceived changes. DESIGN: This cohort study evaluated 290 adolescents from November 2019 to February 2020 (T1-before the pandemic in Brazil) and from June to July 2020 (T2) in southern Brazil. Sociodemographic, behavioural, and psychosocial variables were measured before and during the pandemic. Issues related to social distancing and job loss were also collected. The differences between the variables in T1 and T2, as well as the effect of social distancing, were assessed using a multilevel-adjusted logistic regression model for repeated measures. RESULTS: A total of 207 adolescents were re-evaluated at T2 (a response rate of 71.3%). During the pandemic, the frequency of toothbrushing, the use of dental services, and the self-perceived need for dental treatment significantly decreased. Sugar consumption, bruxism, and quality of sleep did not change significantly. CONCLUSION: Behavioural and psychosocial factors showed significant changes due to the COVID-19 pandemic in adolescents.

RESUMO

BACKGROUND: Instruments adapted for the Mexican population to assess oral health-related quality of life (OHRQoL) in preschoolers remain lacking. This study aimed to cross-culturally adapt and evaluate the psychometric properties of the Mexican version of the Early Childhood Oral Health Impact Scale (M-ECOHIS). METHODS: This cross-sectional study was conducted with preschool children from southern Mexico. The investigation was divided into a transcultural adaptation phase and a validation phase. The M-ECOHIS was completed by the children's guardians, and clinical data were also evaluated. Reliability was evaluated using tests of internal consistency and test-retest measures, while construct validity was assessed through Spearman's correlation coefficient between M-ECOHIS scores and self-reported oral health, and through confirmatory factor analysis (CFA). Construct validity was also evaluated through discriminant validity of the M-ECOHIS, which was determined according to questionnaire scores on oral health measures (e.g., dental caries). RESULTS: A total of 303 preschool children participated in this study. Regarding internal consistency, Cronbach's alpha was > 0.78 for the child section, family section, and general M-ECOHIS. The general intraclass correlation coefficient (ICC) for test-retest reliability was 0.95. The correlation between the scores obtained on the child and family impact sections was significant with the self-reported oral health status rating. In relation to CFA, all items of the M-ECOHIS confirmed the latent variables. Further, M-ECOHIS scores were associated with the presence of untreated dental caries, indicating that the questionnaire has good discriminant validity. CONCLUSION: Our findings suggest that the M-ECOHIS is a valid and reliable instrument for assessing the impact of oral health on quality of life in Mexican preschool children.

RESUMO

INTRODUCTION: The aim of this study was to better understand the interfaces of being correct or incorrect and confident or unconfident; aiming to point out misconceptions and assure valuable questions. METHODS: This cross-sectional study was conducted using a convenience sample of second-year dental students (n = 29) attending a preclinical endodontics course. Students answered 20 multiple-choice questions ("basic" or "moderate" level) on endodontics, all of which were followed by one confidence question (scale). Our two research questions were: (1) How was the students' performance, considering correctness, misconceptions, and level of confidence? (2) Were the questions valuable, appropriate and friendly, and which ones led to misconceptions? Four situations arouse from the interrelationship between question correctness and confidence level: (1st) correct and confident, (2nd) correct and unconfident, (3rd) incorrect and confident (misconception) and (4th) incorrect and unconfident. Statistical analysis (α = 5%) considered the interaction between (a) students' performance with misconceptions and confidence; (b) question's difficulty with correctness and confidence; and (c) misconceptions with clinical and negative questions. RESULTS: Students had 92.5% of correctness and 84.6% of confidence level. Nine students were responsible for the 12 misconceptions. Students who had more misconceptions had lower correctness (P < 0.001). High achieving students had low confidence in their incorrect responses (P = 0.047). 'Moderate' questions had more incorrectness (P < 0.05) and less confidence (P = 0.02) than 'basic'. All questions were considered valuable [for example, the ones that presented images or required a mental picture of a clinical scenario, since they induced less misconception (P = 0.007)]. There was no difference in misconceptions between negative questions and other questions (P = 0.96). CONCLUSION: Preclinical endodontic students were highly correct and very confident in their responses. Students who had more misconceptions had also the lowest performance in the assessment. Questions were valuable; but some will worth further improvement for the future. A multiple-choice assessment, when combined with confidence questions, provided helpful information regarding misconceptions and questions value.

RESUMO

BACKGROUND: Social capital incorporates contextual and individual levels of interactions, which influence human health. The aim of this study was to evaluate the influence of individual and contextual social capital in early childhood on gingival bleeding in children after 7 years. METHODS: This 7-year cohort study was conducted with a randomized sample of 639 children (1 to 5 years old) evaluated in 2010 (T1) in Santa Maria, southern Brazil. Gingival bleeding was recorded during follow-up (T2). Contextual (social class association and number of churches) and individual (religious practice, volunteer networks, and school involvement) social capital variables were collected at baseline, along with demographic, socioeconomic, and oral health variables. A multilevel Poisson regression model was used to investigate the influence of individual and contextual variables on mean gingival bleeding. The incidence rate ratio (IRR) and 95% confidence interval (95% CI) were calculated. RESULTS: A total of 449 children were reassessed after 7 years (70.3% cohort retention rate). Children living in areas with a larger number of churches at baseline had lower mean gingival bleeding at follow-up. Regarding individual social capital, children whose parents did not attend school activities were more likely to have gingival bleeding. Additionally, low maternal education, poor parents' perception of oral health, non-use of dental services, and low frequency of tooth brushing were related to higher mean gingival bleeding at follow-up. CONCLUSION: The presence of more churches in neighborhoods and parents' involvement in a child's school activities positively influenced children's oral health, and these individuals had lower mean gingival bleeding.

RESUMO

PURPOSE: As people around the world are facing the Covid-19 outbreak, their perception of oral health problems could be changed. This study aimed to evaluate the immediate effects of the Covid-19 pandemic on oral health-related quality of life (OHRQoL) of adolescents. METHODS: A cohort study with schoolchildren from southern Brazil was conducted. Data on adolescents' OHRQoL were collected from December 2019 to February 2020 (T1), before the Brazilian Covid-19 outbreak. Posteriorly, the data were collected again in June and July of 2020 (T2), under the Brazilian Covid-19 outbreak. The OHRQoL was assessed using the Brazilian short version of the CPQ11-14. Demographic and socioeconomic characteristics and the degree of social distancing were also assessed. Changes in OHRQoL between T1 and T2 were evaluated by adjusted Multilevel Poisson regression models for repeated measures. RESULTS: From 290 individuals evaluated at T1, 207 were reevaluated at T2 (response rate of 71.3%). The overall CPQ11-14 mean score was significantly lower during the pandemic, reducing from 10.8 at T1 to 7.7 at T2. This significant reduction was also observed for all CPQ domains, indicating a lower negative impact of oral conditions on adolescents' quality of life during the pandemic. Adolescents from families that had a middle or low degree of social distancing during the pandemic and whose parents were harmed in employment had higher CPQ11-14 scores. CONCLUSION: Overall and specific-domains CPQ-14 scores were significantly lower during the Brazilian Covid-19 outbreak, indicating a decrease in the perception of oral health problems by adolescents over that period.

RESUMO

OBJECTIVE: Evaluate the impact of the availability of public dental care service on the increment of dental caries in children. METHODS: This is a 2-year cohort study that followed preschool children from southern Brazil. Dental caries was measured at baseline and follow-up evaluation, considering the number of surfaces with untreated dental caries. Demographic and socioeconomic characteristics as well as the use and availability of dental services were assessed. Multilevel Poisson regression analysis through a hierarchical approach and considering a random effect for repeated measures was used to explore the influence of exploratory variables in the increase in the outcome. RESULTS: A total of 419 cases were evaluated at follow-up (91.3% cohort retention rate). The increase in the untreated dental caries was associated with living in places where there is no regular presence of dentists in the public health system. In addition, the increment of dental caries was influenced by age, household income, and dental attendance. CONCLUSION: The results suggest that the availability of dentists in the public health system have an impact the increment of dental caries among children. The integration of the dentist in the primary healthcare can contribute to decrease the barriers that lead to children's oral health.

RESUMO

BACKGROUND: Toothache is considered a multifactorial health problem that is associated with oral diseases and comorbidities. AIM: Evaluate the direct and indirect pathways between toothache and children's oral health-related quality of life (COHRQoL). DESIGN: This is a cross-sectional study conducted with a random sample of children from southern Brazil. The variables included demographic, socioeconomic, behavioral, and oral health characteristics. Toothache was collected through the question 'Have you had toothache in the last 12 months?'. COHRQoL was collected by the Child Perceptions Questionnaire 8-10 in his Brazilian version. The pathways between the associated variables, toothache, and COHRQoL were analyzed through structural equation modeling. RESULTS: A total of 449 schoolchildren were evaluated. The prevalence of toothache was 50.1% (95% confidence interval: 45.4%-54.8%). The poorer COHRQoL was directly affected by the presence of toothache. Considering the indirect pathways, the low household income, high household crowding, low age, the use of public health service, and the untreated dental caries influenced indirectly in the worst COHRQoL via toothache. CONCLUSION: This study determined that COHRQoL was directly influenced by toothache. Meanwhile, indirect pathways were observed. These findings justify initiatives that highlight the importance of the reduction of oral diseases that can lead to pain experiences.

RESUMO

AIM: To evaluate the influence of the oral conditions and oral health-related quality of life (OHRQoL) on the entry of adolescents on labour. DESIGN: This cohort study was performed in southern Brazil, within a random sample of 12-year-old adolescents (n = 1134). Oral health (dental caries, malocclusion, and toothache), OHRQoL (Child Perceptions Questionnaire 11-14), demographic factors, and family's socioeconomic status (household income and mother's education) were collected at baseline (2012). Education level and employment outcomes, such as labour market entry and earnings from work, were collected at 6-year follow-up. Path analysis was used to estimate the overall fit measurement, standardized coefficients (SC), and its direct and indirect effects. RESULTS: Among 1134 participants, 768 adolescents with mean of age 17.5 years old were reassessed (retention rate of 68%). There was direct effect from poor OHRQoL on labour market entry (SC 0.057; P = .02). Sex and age also had a direct effect on employment outcomes. Socioeconomic status impacts oral health conditions as well as OHRQoL scores (P < .01). Household income, malocclusion, and toothache had indirect effects on labour market entry. CONCLUSION: Oral health indirectly affects employment outcomes, through its effects on OHRQoL. Moreover, OHRQoL directly affects labour market entry in adolescents.
