The association between malocclusion and health-related quality of life in adolescents: A mediation analysis.

This study investigated the role of oral health-related functional limitations and social well-being, self-perceived health, psychosocial factors, and social support in mediating the impact of malocclusion on health-related quality of life (HRQoL). A school-based 6-month cohort study was conducted with 376 12-year-old deprived adolescents. Measures at baseline included malocclusion (DAI score), dental caries, sociodemographic characteristics, psychosocial traits (self-esteem, sense of coherence, oral health beliefs), and social support. The oral health-related functional limitations and symptoms (social well-being) domains of the CPQ11-14 , self-perceived health, and HRQoL (Kiddo-KINDL) were evaluated at the 6-month follow-up. Associations between observed and latent variables (social support, psychosocial factors, and HRQoL) were evaluated using structural equation modelling, according to the Wilson and Cleary theoretical model. Malocclusion was indirectly associated with worse HRQoL, mediated by functional limitations, social well-being, and self-perceived health. Better psychosocial status was directly associated with better HRQoL, and higher social support was indirectly associated with better HRQoL via psychosocial factors. Dental caries experience, female sex, and lower family income were indirectly associated with worse HRQoL. The impact of malocclusion on HRQoL was mediated by oral health-related functional limitations, social well-being, and self-perceived health. Sociodemographic and psychosocial factors, and social support also impacted HRQoL.

Does bullying due to oral conditions influence cigarette smoking in adolescents? A structural equation modeling.

This study aimed to explore the pathways that can influence cigarette smoking among adolescents. This population-based cohort followed a random sample of 12-year-old adolescents from southern Brazil for 6 years. Regular cigarette smoking was assessed through a self-reported question, previously used in the Brazilian National Survey of Scholar Health. We also gathered data on bullying, dental caries at baseline, incidence of caries, sex, friend network, and Sense of Coherence (SOC). Socioeconomic and demographic characteristics were also collected. Structural equation modeling was used to evaluate the pathways. Of the 1,134 adolescents examined at baseline, 768 were re-evaluated (67.7% retention rate). The prevalence of smoking was 37.6%. This prevalence was directly affected by low SOC (SC: -0.14, p < 0.01), low household income (SC: -0.12, p < 0.01), and male sex (SC: 0.15, p < 0.01). Presence of dental caries at baseline indirectly influenced the occurrence of dental bullying at follow-up via the incidence of dental caries (SC: 0.01, p < 0.05). Dental bullying indirectly influenced cigarettes consumption via SOC (SC: 0.62, p < 0.05). Friend network also indirectly influenced the consumption of cigarettes via SOC (SC: 0.32, p < 0.05). Psychosocial factors influence adolescent cigarette consumption through its higher direct and indirect effects (via bullying). In addition, behavioral, sociodemographic, and clinical factors also influence the occurrence of smoking.

Sense of coherence and oral health-related quality of life among southern Brazilian male adolescents.

This study evaluated the association between sense of coherence (SoC) and oral health-related quality of life (OHRQoL) among conscripts of the Brazilian Army, in two cities of southern Brazil. A cross-sectional study included all 18-19-year-old adolescents who joined the Brazilian Army as draftees for mandatory military service in the cities of Itaqui, RS, and Santiago, RS (n = 505). Data collection was conducted from 2019 to 2021, and included the application of questionnaires and a clinical oral examination to record gingivitis, malocclusion, and dental caries. OHRQoL was collected through the Brazilian short version of the Oral Health Impact Profile (OHIP), composed of 14 questions. The adolescents' SoC was assessed using the validated Brazilian version of the SOC-13 scale. The primary outcome of this study was OHRQoL, modeled as a discrete variable (OHIP-14 scores). The main predictor variable was SoC, categorized as low, moderate, or high. The association between predictor variables and OHRQoL was assessed by Poisson regression models using a hierarchical approach. Unadjusted and adjusted rate ratios (RR), and 95% confidence intervals (CI) were estimated. All the analyses were performed using STATA software version 14.2. Adolescents with a moderate and high SoC had 27% (RR = 0.73, 95%CI = 0.64-0.84) and 51% (RR = 0.49, 95%CI = 0.41-0.58) lower mean OHIP-14 scores, respectively, than those with a low SoC score, after the inclusion of behavioral and clinical variables. This study showed a significant association between SoC and OHRQoL among 18-19-year-old southern Brazilian adolescents. Strengthening the SoC as a psychosocial resource may improve the well-being and OHRQoL of adolescents.

Impact of oral diseases on 12- and 15-year-old children's quality of life: condition-specific oral health related quality of life analysis.

BACKGROUND: Oral diseases can affect children's quality of life. The aim of the present study was to assess the Condition-Specific (CS) impacts from oral diseases in 12- and 15-year-old Thai population using data from the two consecutive national oral health-related quality of life surveys. METHODS: The oral health-related quality of life surveys were conducted for this study as a part of 6th and 7th national oral health survey. The study sample of 1,066 12- and 815 15-year-olds from 6th national oral health survey; and 556 12- and 351 15-year-olds from 7th national oral health survey were from Bangkok and four regions of Thailand. Oral impacts were assessed by the Child-Oral Impacts on Daily Performances index for 12- and Oral Impacts on Daily Performances index for 15-year-olds. The overall impacts and CS impacts attributed to oral diseases were calculated. The detailed characteristics of the CS impacts were analyzed. Cochran's Q test and McNemar's test were used to determine the difference between the proportions of CS impacts of caries, gingival diseases, oral lesions, and malocclusion. RESULTS: CS impacts-caries were prevalent for both age, followed by gingival disease and oral lesions. CS impacts-caries were the highest in the intensity and extent for both age groups. CS impacts-caries were significantly higher than those of gingival diseases for eating, speaking, relaxing, emotional state, and studying. CS impacts-gingival disease was significantly higher than caries for cleaning in one survey. CONCLUSIONS: CS impacts-caries were the most prevalent and severe among adolescent. Gingival disease was infrequently related to severe impacts on daily performances.

Evaluation and relation of oral health-related quality of life and oral health status in Thalassemia Major patients, a cross-sectional study.

BACKGROUND: Beta-Thalassemia is the most common human inherited disease, directly impacting patients' physical and psychosocial aspects. The present study evaluated oral health status, oral health-related quality of life (OHRQoL), and their correlation in Thalassemia Major patients. METHODS: Two hundred Thalassemia Major patients aged 12-49 participated in this cross-sectional study. Subjects were selected among the patients referred to the Faculty of Dentistry of Isfahan University of Medical Sciences using simple sampling. Oral Health Impact Profile 14 (OHIP 14) was used to assess OHRQoL. The decayed, Missing, and Filled Teeth (DMFT) index was used as an oral health index. SPSS 22 was used for analysis, using T and Pearson Correlation tests. RESULTS: 53% of participants were female, and 47% were male. The mean OHIP-14 score (± SD) was 13.20 (± 7.01). The mean DMFT score was 9.54 (± 5.72). DMFT and total OHIP 14 scores correlated significantly (p < 0.001, r = 0.78). All domains of the OHIP-14 score were also significantly correlated with DMFT (p < 0.05). CONCLUSIONS: Poor oral health conditions might adversely affect OHRQoL in TM patients. It seems necessary to provide oral treatment needs in order to improve OHRQoL in patients suffering from this particular disease.

Psychosocial associated factors of early childhood caries and oral health-related quality of life: Structural equation model approach.

OBJECTIVE: To identify a structural model for the identification of psychosocial associated factors of early childhood caries (ECC) and oral health-related quality of life (OHRQoL) in preschool children and their families. METHODS: A population-based cross-sectional study was conducted with 533 preschool children from 4 to 6 years-old public and private preschools, from Ribeirão das Neves, MG. Parents/caregivers self-completed the Brazilian versions of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and Resilience Scale as well as a structured questionnaire addressing socioeconomic status and child's oral health behavior. Two dentists who had undergone training and calibration exercises for ICDAS­epi and pufa index (Kappa≥0.95) performed the examinations for ECC. Stages of ECC were classified as free of visible carious lesion, initial caries, moderate caries, extensive caries without pulp consequences and extensive caries with pulp consequences. Data were analyzed using structural equation modeling, using Mplus version 8.6. RESULTS: Lower socioeconomic status (b=-0.250; p<0.001) and higher frequency of free sugar consumption (b = 0.122; p = 0.033) were directly associated with a more severe stage of ECC. Lower parental resilience had an indirect impact on more severe stage of ECC which was mediated by the variable 'frequency of free sugar consumption' (b=-0.089; p = 0.048). ECC was associated with lower child's OHRQoL (b = 0.587; p<0.001) and lower family's OHRQoL (b = 0.506; p<0.001). CONCLUSION: Structural modeling revealed that the severity of ECC negatively impacted the OHRQoL of preschoolers and their families. The main associated factors of the severity of ECC were lower socioeconomic status, higher frequency of free sugar consumption and lower parental resilience. CLINICAL SIGNIFICANCE: T The findings indicate that psychosocial and behavior variables can be associated with the severity of ECC, and ECC can be associated with negative impact on wellbeing and ability to perform daily activities of preschoolers and their families.

Caries dental y calidad de vida de escolares de 6 a 8 años / Dental caries and quality life of schoolchildren aged 6 to 8 years

Introducción: la caries dental ocasiona dolor y alteración de la salud. La calidad de vida se refiere a la percepción de uno con base en su situación física, emocional y social. Objetivo: analizar la percepción de la calidad de vida en un grupo de escolares con caries. Metodología: 270 escolares de 6-8 años de edad con y sin experiencia de lesiones cariosas contestaron con sus padres un cuestionario basado en la Scale of Oral Health Outcomes (SOHO). Las respuestas se registraron con escala de tipo Likert. Se obtuvieron frecuencias, porcentajes, promedios y desviación estandar. Se compararon los grupos con chi cuadrada y t de Student, y se calculó la razón de momios (RM). Resultados: el 58% presentó experiencia de caries. El 64% de los escolares con caries informó que tenía antecedentes de dolor dentario y la media en los dominios sobre funciones bucales y relación familiar fue mayor para los escolares con caries (p = 0.001). Tener caries fue determinante para presentar dificultades para comer: RM 8.7 (intervalo de confianza del 95% [IC 95%] 4.7-16); beber: RM 5.9 (IC 95% 3.4-10); dormir: RM 5.3 (IC 95% 3.1-9); jugar: 5.2 (IC 95% 2.7-10), p < 0.001. Desde la autopercepción del escolar, el 87% manifestó no sentirse contento por la presencia de caries. Conclusiones: la percepción de los escolares y padres del grupo con experiencia de caries dental mostró deterioro en la calidad de vida.

Background: Dental caries causes pain and alteration of integral health. Quality of life refers to oneself's perception of their physical, emotional and social situation. Objective: To analyze the perception of quality of life in a group of schoolchildren with caries. Methodology: 270 schoolchildren aged 6-8 years with and without experience of carious lesions, with their parents, answered a questionnaire based on the Scale of Oral Health Outcomes (SOHO). The answers were recorded with a Likert-type scale. Frequencies, percentages, averages and standard deviation were obtained. The groups were compared with chi squared and Student's t test, and odds ratios (OR) were calculated. Results: 58% presented caries experience. 64% of schoolchildren with caries reported antecedents of dental pain, and the mean in the domains on oral functions and family relationship was higher for schoolchildren with caries (p = 0.001). Having caries was determinant for eating difficulties: OR 8.7 (95% CI 4.7-16); drink: OR 5.9 (95% CI 3.4-10); sleeping: OR 5.3 (95% CI 3.1-9); play: OR 5.2 (95% CI 2.7-10), p < 0.001. From schoolchildren auto-perception 87% said they did not feel happy about their decayed teeth. Conclusions: The perception of the schoolchildren and parents belonging to the group with experience of dental caries showed deterioration in the quality of life.

Impact of gingivitis on oral health-related quality of life in 12-year-old schoolchildren of Quito, Ecuador.

PURPOSE: Evaluate the impact of gingivitis on oral health-related quality of life (OHRQoL) amongst 12-year-old schoolchildren from Quito, Ecuador. METHODS: We evaluated 998 school children using the Community Periodontal Index for gingival bleeding and calculus. OHRQoL was assessed with the Child Perceptions Questionnaire 11-14 (CPQ11-14) questionnaire. RESULTS: Of the 998 schoolchildren, 93% had gingival bleeding and 73% had dental calculus. Schoolchildren with more than one sextant with gingival bleeding had 1.18 times higher mean CPQ11-14 (RR 1.18, 95% CI 1.11-1.27) than those with none or just one affected sextant. Male schoolchildren presented a 15% lower mean Child Perceptions Questionnaire (CPQ) (RT 0.85; 95% CI 0.76-0.96). Children whose parents had incomplete secondary education had a 15% lower mean CPQ (RT 0.85; 95% CI 0.77-0.94). Bleeding in more than one sextant was significantly associated with worse quality of life in the emotional well-being (RT 1.40, 95% CI 1.03-1.90) and social well-being domains (RT 1.76, 95% CI 1.32-2.34). CONCLUSION: Gingival bleeding negatively impacted the OHRQoL of 12-year-old Ecuadorian schoolchildren living in Quito.

Evaluation of the predictors of oral health-related quality of life among 3-5-year-old children with dental trauma.

This study evaluated the influence of socio-demographic, clinical, and parental psychological factors on oral health-related quality of life (OHRQoL) and determined their predictors in preschool-aged children with traumatic dental injury (TDI). The study sample consisted of 324 dyads of children and their parents attending the Clinics of Pediatric Dentistry at Istanbul University. After clinical examination, the Sense of Coherence (SOC), Generalized Self-Efficacy Scale, Early Childhood Oral Health Impact Scale, and Multidimensional Health Locus of Control Scale-MHLC questionnaires were administered to the parents. The statistical analyses included Spearman correlation coefficients, Mann-Whitney U tests, Kruskal-Wallis tests, multiple linear regression, and confirmatory factor analysis. Having mixed TDI, a non-nuclear family, fewer children, and weak parental SOC were important predictors of worse overall OHRQoL and its sections of child and family. Lower internal health locus of control and dental pain due to TDI were predictors of worse overall OHRQoL and child impact, respectively. Consideration of these predictors may help oral health professionals to develop prevention and treatment programs for TDI and oral health literacy programs for families.

Sense of coherence moderates the relationship between perceived racial discrimination and oral health-related quality of life in schoolchildren.

AIM: To evaluate the moderating effect of the sense of coherence (SOC) in the relationship between racial discrimination and oral health-related quality of life (OHRQoL) in schoolchildren. METHODS: This is a cross-sectional study nested in a cohort performed in southern Brazil. OHRQoL was assessed using the short version of the Child Perceptions Questionnaire 11-14 (CPQ11-14). The perception of racial discrimination was measured using a question contained in the Bullying Questionnaire by Olweus, and SOC through the shortened version of the 13-item Sense of Coherence Scale. Sociodemographic and dental caries following the International Caries Detection and Assessment System (ICDAS) characteristics were also collected. A simple slop test and Poisson regression analysis were performed to test the interaction effects of the predictors on OHRQoL. RESULTS: A total of 429 schoolchildren were included in this study. About 6.7% reported had perceived racial discrimination. The simple slope test indicated that the negative effects of racial discrimination on OHRQoL were significant under different SOC levels. Among schoolchildren who suffered racial discrimination, those who had higher SOC reported lower impact on OHRQoL when compared to those with low SOC. CONCLUSION: SOC can be considered a moderating variable in the relationship between racial discrimination and OHRQoL. CLINICAL SIGNIFICANCE: These findings highlight that psychosocial factors such as SOC could attenuate the impact of perceived discrimination on OHRQoL in adolescence.

Family functioning and preschool children's oral health-related quality of life.

INTRODUCTION: Identifying which aspects of how a family functions are relevant to child oral health provides opportunities for interventions targeting the family context. The aim of this study was to investigate the associations of general and domain-specific family functioning with oral health-related quality of life (OHRQoL) of 3-4-year-old children. METHODS: Cross-sectional data from 740 parent-child dyads from East London were analysed. Family functioning was assessed with the 60-item Family Assessment Device that yields scores for general functioning and six domains (roles, behaviour control, communication, affective involvement, affective responsiveness and problem solving). Children's OHRQoL was measured using the Early Childhood Oral Health Impact Scale (ECOHIS), which measures the lifetime impacts of children's oral conditions on the child (child impact section, CIS) and family (family impact section, FIS). The associations of family functioning with the ECOHIS total, CIS and FIS scores were assessed in negative binomial regression models (rate ratios [RR] and 95% confidence intervals [95% CI] were calculated), adjusting for parental sociodemographic factors and child demographic factors and caries experience. RESULTS: Children in families with unhealthy general functioning had 1.45 (95% CI: 0.87-2.43), 1.24 (95% CI: 0.73-2.13) and 2.19 (95% CI: 1.20-3.99) times greater ECOHIS total, CIS and FIS scores, respectively, than those in families with healthy general functioning after adjustment for confounders. Unhealthy functioning in the roles domain was associated with greater ECOHIS total and FIS scores. Unhealthy functioning in the problem solving, roles and affective involvement domains were also associated with greater FIS scores. CONCLUSIONS: Unhealthy family functioning was associated with worse child OHRQoL, especially in terms of disrupting family life. Effective assignment and undertaking of roles should be further explored as a target for intervention.

Oral Diseases and Oral Health-Related Quality of Life among Kenyan Children and Adolescents with HIV.

INTRODUCTION: Children and adolescents living with HIV (CALHIV) have a higher risk of hard and soft oral tissue diseases as compared with their healthy peers. It is important to increase awareness regarding the need to integrate oral health within medical care among pediatric HIV populations. Studies on associations of oral diseases with oral health-related quality of life (OHRQoL) in CALHIV are lacking. This study examined the association between oral diseases and OHRQoL in Kenyan CALHIV. METHODS: This cross-sectional analysis was nested in a longitudinal cohort study of CALHIV in Nairobi. CALHIV received oral examinations, and the World Health Organization's Oral Health Surveys and Record Form was administered. OHRQoL was measured with the Parental-Caregiver Perceptions Questionnaire, with the subdomains of global, oral symptoms, function limitations, and emotional and social well-being, with higher scores indicating poorer OHRQoL. Linear regression was used to model associations between OHRQoL and oral diseases, adjusting for age at the time of oral examination, CD4 counts, and caregiver's education. RESULTS: Among 71 CALHIV, the mean age was 12.6 y (SD, 2.9; range, 10 to <21), and the mean composite OHRQoL score was 12.6 (SD, 11.2). Ulcers (not herpes simplex virus or aphthous) were associated with the worst overall OHRQoL (mean, 21.8; SD, 11.1; P = 0.055) and oral symptoms subdomain (mean, 7.0, SD, 2.5; P = 0.003). Children with dry mouth and untreated caries had significantly higher mean global OHRQoL scores than those without disease (P < 0.0001). In the multivariate analysis, the OHRQoL composite score was 6.3 units (95% CI, -0.3 to 12.9) higher for those who had dry mouth and untreated dental caries; dry mouth accounted for the highest percentage of variability of OHRQoL (9.6%) and the global subdomain (31.9%). Ulcers accounted for the highest percentage of variability of the oral symptoms domain (15.4%). CONCLUSIONS: Oral ulcers, dry mouth, and untreated caries were associated with poorer OHRQoL in CALHIV. Integrating oral health into the primary care of CALHIV may improve their OHRQoL. KNOWLEDGE TRANSFER STATEMENT: This study aimed to determine the association of oral diseases with the oral health-related quality of life of children and adolescents living with HIV (CALHIV). The findings will form part of the evidence to incorporate oral health protocols into care programs for CALHIV. Oral health monitoring has the potential to increase the surveillance of HIV clinical status, monitor the effectiveness of antiretroviral therapy, and improve the oral health-related quality of life of CALHIV.

Unraveling the signs and symptoms of oral conditions that affect daily life activities and oral health-related quality of life.

OBJECTIVES: Since oral conditions negatively affect oral health-related quality of life (OHRQoL), this study evaluated which oral clinical condition, signs, and symptoms are associated with the impact on OHRQoL, its domains, and specific daily life activities among adults. MATERIALS AND METHODS: Data from a probabilistic sample of adults (35-44 years old) was used. The Oral Impacts on Daily Performance (OIDP) was used to evaluate OHRQoL, its domains (physical, psychological, and social), and nine daily life activities. Signs and symptoms of oral diseases (dental caries, periodontal disease, need for dental prothesis, and tooth loss) and oral self-perception were considered. Descriptive, bivariate, and multi-level analyses were conducted. RESULTS: A total of 5,834 adults were included, of which 52.9% had some negative impact of oral conditions on OHRQoL. Difficulty in eating was the most affected daily life activity. For multiple models, dental caries lesions (cavities), filled teeth with caries, gingival bleeding, periodontal pocket, dental pain, need for upper or lower dental prosthesis, and oral health self-perception were associated (p < 0.05) with overall OHRQoL or at least one of its domains. The impact on daily life activities of each individual was associated with at least one oral condition. Dental caries lesions (cavity) and dental pain were associated (p < 0.05) with the impact on most daily life activities evaluated. CONCLUSIONS: Different signs and symptoms of prevalent oral diseases are associated with the impact on specific daily life activities among adults, which may compromise the OHRQoL. CLINICAL RELEVANCE: Knowledge of how signs, symptoms, and oral conditions affect OHRQoL and daily life activities can provide essential information for clinicians to establish proper disease management and preventive strategies focusing on improving patients' lives.

Impacts of the COVID-19 Pandemic Exposure on Child Dental Caries: Difference-in-Differences Analysis.

The impact of the coronavirus disease 2019 (COVID-19) pandemic on dental caries is unknown. We investigated the effect of the pandemic on child dental caries in Japan by comparing the increase in dental caries from fourth to sixth grade between two cohorts, COVID-19 exposed cohort and COVID-19 unexposed cohort, using difference-in-differences analysis. Longitudinal data that followed elementary school children in Adachi City, Tokyo, were analyzed. The analysis consisted of two cohorts: those who were in fourth grade in 2016 and sixth grade in 2018 (COVID-19 unexposed cohort, N = 399) and those who were in fourth grade in 2018 and sixth grade in 2020 (COVID-19 exposed cohort, N = 3,082). Children's dental caries were examined by school dentists. A difference-in-differences analysis, adjusting for time-variant variables, i.e., household socioeconomic status, children's oral health behavior, and caregivers' psychological distress, was performed. In fourth grade, the number of Decayed, Missing, and Filled permanent Teeth (DMFT) was not different between the COVID-19 unexposed and exposed cohorts (mean = 0.241 and 0.242, respectively). In sixth grade, DMFT increased by 0.067 in the COVID-19 unexposed cohort and 0.180 in the COVID-19 exposed cohort. The interaction term of grade and cohorts for caries by difference-in-differences analysis showed that dental caries among the COVID-19 exposed cohort showed a significant increase in the number of dental caries by 0.116 (95% confidence interval 0.015, 0.216) compared to the COVID-19 unexposed cohort. Child dental caries slightly increased after the pandemic. Studies with longer follow-ups are needed to evaluate the impact of the pandemic on child dental caries.

Relationship between sense of coherence, OHRQoL, and dental caries among nursing students in South India.

Background: Dental caries is one of the most common dental diseases that affect all population and is associated with the avoidance of care. Research has reported that sense of coherence (SOC) is related to many aspects of health including oral health. SOC determines the quality of health and might have a direct association with the development of subjective assessments of oral health. Objectives: To find the association between SOC, Oral Health-Related Quality of Life (OHRQoL) and caries status among nursing college students in southern state of India. Design: Cross-sectional design using questionnaire and assessment of caries status. Participants: Nursing students from south India. Methods: Convenience sampling method was followed and students who were present on the day of the study and consented to participate were included in the study. The total study sample consisted of 494 nursing students. SOC and OHRQoL were measured by a self-administered questionnaire; caries status was assessed using Decayed, Missing and Filled Tooth (DMFT) index. Results: Association between SOC and Oral Health Impact Profile (OHIP) and caries status and OHIP was found to be statistically significant. Correlation between dental caries and OHIP was found to be statistically significant, with R-value -0.251 shows that OHIP is negatively correlated with caries status. Conclusion: SOC as a psychosocial resource is capable of facilitating the motivation for positive oral health behaviours. These resources along with socio-economic and demographic factors can create an environment that is partially responsible for the individuals' cognitive and physical functions that can express themselves as the individuals' well-being and positive health behaviours.

Effect of Treatment with Selective Caries Removal Associated to Antimicrobial Photodynamic Therapy on Children's Oral Health-Related Quality of Life: A Non-Randomized Clinical Study.

How patients perceive impact of diseases is an essential component when characterising different disease impacts, and effects of dental treatments should be perceived by the patients. This study aimed to assess the impact of conservative treatment of deep caries lesions using the selective caries removal (SCR) associated to a low laser therapy (antimicrobial photodynamic therapy-aPDT) on oral health-related quality of life (OHRQoL). STUDY DESIGN: A non-randomized clinical before-and-after study was conducted on children aged 4 to 8 years. The data was obtained applying the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS) to the caretakers in an interview before and after treatment. The paired T-student test considering p<0.05 and the treatment responsiveness detecting the effect size by means of standardized response mean (SRM) was evaluated. RESULTS: The mean impact on OHRQoL on the total scale was 5.46 ± 4.54 for before and 2.42 ± 3.54 for after treatment (p<0.01). The ECOHIS demonstrated satisfatory longitudinal responsiveness except for psychological, self-image/social interaction and Family function domain (SRM<0.5). CONCLUSION: This study demonstrated that the association of a low laser therapy (aPDT) with SCR did not influence negatively on OHRQoL. In the practice of pediatric dentistry, this conservative dental treatment improved the OHRQoL after 3 months of follow up.

The role of dental pain and psychosocial factors on the relationship between dental caries and oral health-related quality of life in children.

BACKGROUND: To examine the role of dental pain, sense of coherence (SOC) and social support on the relationship between dental caries and oral health-related quality of life (OHRQoL) in children aged 12 years. METHODS: A cross-sectional study involving 400 schoolchildren selected from public schools in a socioeconomically disadvantaged region in the city of Manaus, Brazil was carried out. The predictors of OHRQoL were selected according to the Wilson and Cleary theoretical model, including number of decayed teeth and its clinical consequence (component D of the DMFT index and PUFA/pufa index), dental pain (symptom status), and SOC and social support (individual and environmental characteristics). Statistical analysis was conducted through structural equation modelling and multivariable negative binomial regression. The significance level established for all analyses was 5%. RESULTS: Number of dental caries was indirectly linked with OHRQoL (ß = 0.19, 95% CI 0.11/0.29) through dental pain, SOC and social support. Clinical consequences of untreated caries directly predicted poor OHRQoL (ß = 0.12, 95% CI 0.01/0.23). Dental pain, SOC and social support did not moderate the effect of dental caries measures on OHRQoL. CONCLUSION: Our findings suggest the role of dental pain, SOC and social support as mediator factors on the link between dental caries and OHRQoL. Tackling dental caries along with psychosocial factors may attenuated the impact of oral health on OHRQoL in children.

Validation of the French version of COHIP-SF-19 among 12-years children in New Caledonia.

BACKGROUND: Assessment of oral health-related quality of life is now associated to clinical indicators in epidemiological studies. This study aimed at validating the French Short Form of the Child Oral Health Impact Profile (COHIP-SF-19) and assessing the impacts of oral diseases among schoolchildren in New Caledonia (NC). METHODS: A sample of 12-years-old children (n = 971) was selected in 2019 in NC using a random, stratified, and clustered sampling technique. Children filled the French COHIP-SF-19 questionnaire. Information on sociodemographic characteristics, oral hygiene habits, perception of oral health problems were also collected through self-administered questionnaires or from the schools' database. Dental status (dental caries, gingival status, and dental functional units) was clinically recorded at school by four calibrated examiners. Cronbach's alpha and intraclass correlation coefficients (ICC) were calculated. Kruskal-Wallis tests and spearman correlations were used along with multilevel mixed models taking into account the cluster and examiner effects. A confirmatory factor analysis was conducted and sensitivity analyses were performed. RESULTS: Among the 693 children examined, 557 children were included. Oral diseases were frequent in the study population 40% had dental caries and 55% presented gingivitis. The COHIP scores ranged from 7 to 76 (57.9 ± 9.96) with 96.4% of the children having experienced oral health problems, 81.7% reporting functional impacts and 90.5% socio-emotional impacts. Overall, the French COHIP-SF-19 showed satisfactory psychometric characteristics. Internal consistency was high (Cronbach's alpha = 0.80) and reproducibility excellent (ICC = 0.9). Discriminant and concurrent validity were adequate. Indeed, children with less optimal social situation, impaired dental status, declaring severe dental problems or difficulties in accessing oral health care showed lower COHIP-SF-19 scores. Factor analyses suggested a four-component structure with identification of a new domain (self -image) and changes in the repartition of the items within the original domains. Sensitivity analyses showed similar results for children with partial or complete answers in the COHIP questionnaire. CONCLUSIONS: The French COHIP-SF-19 showed satisfactory psychometric characteristics and allowed to identify the high impacts of oral diseases in New Caledonian children, namely for socially deprived children.

Dental fear in school children and young adults attending public dental health care: prevalence and relationship to gender, oral disease and dental treatment; trends over 40 years.

PURPOSE: To study prevalence of dental fear and the relationship to gender, oral disease and dental treatment between 1973 and 2013 in school children and young adults attending public dental health care. METHODS: Every ten years from 1973 to 2013 random samples of about 100 individuals in each of the age groups 10, 15 and 20 years took part in a repeated cross-sectional study based on clinical parameters and a questionnaire. Dental fear was estimated by the question: "What do you feel at the prospect of an appointment with a dentist?". 75-99% of the samples answered the question. Agreement to at least one of the alternative answers: ill at ease, frightened and sick defined dental fear. Frightened and/or sick indicated severe dental fear. The prevalence of caries, gingivitis and number of filled tooth surfaces were calculated. Chi-square tests were used to show differences in proportions between groups and linear regression to show trends over time. RESULTS: Prevalence of dental fear declined in all age groups over time. In the 20-year olds dental fear was found in 29% of the sample and severe dental fear in 12% of girls and 5% of boys in 2013. Individuals with dental fear had higher mean caries prevalence and number of filled tooth surfaces compared with individuals without dental fear. CONCLUSIONS: This 40-year time trend study showed a reduction in dental fear prevalence in school children and young adults offered regular public dental health care based on prevention and a psychological approach. The prevalence of dental fear was still high in 2013 despite a significant decline in caries during the study period. Further improvements in the psychological approach when treating children are thus needed.

Sociodemographic and Clinical Factors That Influence Oral Health-Related Quality of Life in Adolescents: a Cohort Study.

OBJECTIVE: To determine the sociodemographic and clinical factors that may influence oral health-related quality of life (OHRQoL) at ages 12 to 15. BASIC RESEARCH DESIGN: Cohort study. PARTICIPANTS: Cluster-randomized sample of Hong Kong 12-year-olds. MAIN OUTCOME MEASURES: The Child Perceptions Questionnaire (CPQ11-14) was used to measure OHRQoL as the response variable. Periodontal status and caries were examined according to WHO criteria. Malocclusion was assessed using Dental Aesthetic Index. Potential predictors of OHRQoL (age, gender, father's education, mother's education, household income, periodontal status, caries, and malocclusion) were analyzed by structural equation modelling. RESULTS: At age 12, 589 participants (305 females, 284 males) were included. At age 15, 331 (172 females and 159 males) were followed up. For direct effects, age 15 was associated with higher oral symptoms (OS) scores (ß=0.124, 95%CI=0.049 to 0.2) but lower emotional well-being (EWB) scores (ß=-0.105, 95%CI=-0.184 to -0.03). Males had higher OS scores than females (ß=0.126, 95%CI=0.059 to 0.208). Mother's education had positive effects on children's EWB (ß=-0.096, 95%CI=-0.159 to -0.018). Malocclusion had negative effects on functional limitations (FL) (ß=0.083, 95%CI=0.013 to 0.186). For indirect effect, mother's education showed a link via EWB to OHRQoL (ß=-0.077, 95%CI=-0.123 to -0.018). Malocclusion showed a link via FL to OHRQoL (ß=0.037, 95%CI=0.006 to 0.087). CONCLUSIONS: Age, gender, mother's education and malocclusion predicted OHRQoL at ages 12 and 15.
