Is there an Association between Oral Health Status and School Performance? A Preliminary Study

Mothers' Knowledge, Attitude, and Behavior Concerning Their Kindergarten Children's Oral Health: A Cross-Sectional Study

OBJECTIVES

To evaluate the level of oral health-related knowledge, attitudes, and behavior among a group of mothers with kindergarten (KG) children aged 3-5 years toward their own and their children's oral health and assess its influence on their children's oral health status.

MATERIAL AND METHODS

This was a cross-sectional study conducted in Jeddah, Saudi Arabia. The sample was selected randomly from public and private KGs in Jeddah. Self-administrated questionnaires were distributed to the mothers of KG schoolchildren aged 3-5 years, which contained translated and validated Mothers' Behavior Questionnaire about their own oral health behaviors, Mothers' Attitude Questionnaire about their children's oral health, and Mothers' Knowledge Questionnaire about their children's oral health. The oral health of the KG school children was examined to determine the decayed, missed, and filled index (dmft).

RESULTS

A total of 461 child-mother pairs completed the study. The mean values of dmft were 5.41 ± 4.81. The children's oral health (dental caries) and the mothers' oral health-related knowledge, attitudes, and behavior were significantly associated with KG type (public vs. private), mothers' age, mothers' education, and family income. A multiple linear regression model indicated that younger mothers (< 30-40 years), highly educated mothers, high family income, and mothers with higher knowledge scores were significantly associated with lower dmft scores.

CONCLUSIONS

Mothers whose children attended private KGs exhibited better oral health-related attitudes, habits, and knowledge. School type, mother's age, mother's education level, and monthly income were factors that strongly impacted the behaviors, attitudes, and knowledge of the mothers. Dental caries was lower among children whose mothers were young, well-educated, from high family income families, and had higher knowledge related to oral health. Implementing targeted educational programs for mothers, particularly those with lower educational attainment and from low-income backgrounds, is essential for enhancing the oral health of children in kindergarten age.

Dental caries and school readiness in 5-year-olds: A birth cohort data linkage study

OBJECTIVE

To describe the association between dental caries and school readiness in 5-year-old children taking part in the Born in Bradford (BiB) birth cohort, UK.

METHODS

The Early Years Foundation Stage Profile (EYFSP) assesses the school readiness of young children and is strongly predictive of future academic attainment. Children are recorded as 'emerging' (below expected), 'expected', or 'exceeding' in five key learning areas. The Oral Health Survey of 5-year-olds (OHS5) is undertaken biennially in England, assessing caries experience at a dentine threshold (d3mft). EYFSP and OHS5 were available for a proportion of children participating in BiB. Odds ratios and confidence intervals for caries experience were established, and odds ratios adjusted for significant sociodemographic variables.

RESULTS

EYFSP and OHS5 data were available for 2.5% (n = 346) BiB participants. Nearly half (45.2%) had caries. A measure of socio-economic status, receiving free school meals, was the only demographic variable strongly related to caries experience (OR: 2.8, 95% CI: 1.6-4.9). After adjustment, children 'emerging' in EYFSP learning areas had 1.6- to 2.2-fold (95% CI: 1.0-3.8) higher odds of experiencing caries. Children 'exceeding' EYFSP learning areas had 2.3- to 4-fold (95% CI: 0.1-0.9) lower odds of caries experience.

CONCLUSION

This is the first study to explore the association between caries experience and school readiness using a holistic assessment tool. The association was found across different learning areas and was comparable to and independent of socio-economic status. The findings indicate oral health-related absenteeism is not a causative factor. EYFSP shows potential to enhance the targeting of preventive interventions at a child, class or school level.

Does poor oral health impact on young children's development? A rapid review

Background The extent to which poor oral health in young children impacts developmental milestones is unclear.Aim To review the evidence of association between poor oral health and development of young children (0-5 years).Method A rapid review was conducted. Medline was searched for articles in English published from 2000 onwards. The outcomes considered were the impact of poor oral health on speech and language development, oral health-related quality of life (OHRQoL), school performance and attendance.Results In total, 15 studies were included: four systematic reviews, a critical review and 10 primary studies. All data were from observational or cross-sectional studies. Premature extraction of primary maxillary incisors was associated with change in speech sounds and articulation. Two primary studies found associations between early childhood caries and physical and psychomotor deficiencies, while acknowledging a web of causation with other factors, including socioeconomic status. Children with dental caries reported lower OHRQoL. Studies found caries experience was associated with preschool absenteeism.Conclusion Poor oral health in young children appears to be associated with speech and language development, OHRQoL, and school attendance and performance. However, there are significant limitations in the existing evidence, with further high-quality, observational, longitudinal research required to fully understand the impact of poor oral health on the development of young children. Strategies to improve oral health by health and education professionals are needed to ensure young children reach their potential.

School type and oral conditions associated with school performance and absenteeism in adolescents: A multilevel analysis

BACKGROUND

Investigations assessing how oral health status affects school performance and attendance considering individual and community variables are lacking.

AIM

To analyze the association of school contextual factors and oral conditions with school performance and absenteeism in early adolescence.

DESIGN

This cross-sectional study was carried out with 593 12-year-old students from 20 schools in Passo Fundo, a southern city in Brazil. The caregivers provided sociodemographic information by means of a questionnaire. Oral health status was clinically examined for dental caries and gingival bleeding. Students answered the CPQ11-14 questionnaire to assess the oral health-related quality of life (OHRQoL). Information on contextual factors was obtained from the schools' administrators. "School performance" was measured by Portuguese and Mathematic tests' scores, and "school absenteeism" by the number of school days missed. Descriptive statistics was conducted, followed by unadjusted and adjusted multilevel linear regression.

RESULTS

At the individual level, low OHRQoL was associated with lower school performance and higher absenteeism. At the contextual level, students from private schools had higher school performance and lower mean of school days missed.

CONCLUSIONS

The type of school and OHRQoL were associated with school performance and attendance of adolescents.

The relationship of children's dental clinical status with school performance and school attendance in the Kingdom of Bahrain: A life-course approach

OBJECTIVES

To examine the association between dental clinical status and school performance and school attendance in the Kingdom of Bahrain (KoB) using a life-course framework.

METHODS

This time-ordered cross-sectional study included 466 school children in Grade 2 (aged 7-8 years) and their parents in the KoB. Data were collected through parents' self-administered questionnaires, children's face-to-face interviews and dental clinical examinations. Data on children's school performance and school attendance were gathered from parents and school records. Structural equation modelling (SEM) examined the direct and indirect pathways between variables.

RESULTS

Children born in families with high socio-economic status (SES) were less likely to have dental caries and more likely to have better school performance at 7-8 years of age. Dentine caries was directly linked with poor school performance. Treated teeth directly predicted high school performance. The presence of dentine caries mediated the relationship of SES with school performance.

CONCLUSIONS

Birth and current socio-economic factors were significant predictors of dental clinical conditions and school performance. Dental caries and fewer treated teeth directly predicted poor school performance.

The prevalence of early childhood caries and treatment needs among children attending Anganwadi centers in Goa state: A cross-sectional survey

CONTEXT

The prevalence of early childhood caries (ECC) is widespread, as reported in studies conducted in various states across India. Many children residing in the rural areas attend Anganwadi centers for preprimary education, nourishment, and health care.

AIM

The aim of the study was to determine the prevalence of ECC among children attending Anganwadi centers in the state of Goa and their treatment needs.

SETTINGS AND DESIGN

The study was approved by the Institutional Ethical Committee of Goa Dental College and Hospital. The study was carried out in Anganwadi centers spanning the various districts and talukas of Goa state.

MATERIALS AND METHODS

The decayed, missing, and filled teeth (dmft) index was recorded in 3-5-year-old children along with treatment needs as per the modified WHO pro forma.

STATISTICAL ANALYSIS

Statistical software (STATA) for data science by StataCorp LLC (version 17), descriptive statistics, and Chi-square test.

RESULTS

A total of 386 children were examined, out of which 47% had ECC. The prevalence of ECC was highest in Canacona and the least in Tiswadi talukas. The severity and occurrence of ECC were found to the proportional to age. With regard to treatment needs, 8.55% needed restoration of at least one surface, 10.88% needed restoration of 2 or more surfaces, 5.44% required a crown, 11.4% needed pulpal treatment, and 6.74% needed extractions. Within the dmft component, the percentage of decayed teeth was 46.89%, followed by filled (0.52%) and missing (0.52%) teeth.

CONCLUSION

The prevalence and severity of ECC in children attending Anganwadi centers in Goa were found to be large and proportional with increasing age.

Oral Health and Academic Achievement of Children in Low-Income Families

Low-income children have higher rates of unmet oral health needs. Prior research suggests that poor oral health is associated with lower academic performance but uses cross-sectional and mostly parent-reported measures. This study examined the association between oral health during the first 5 y of life and subsequent academic achievement for low-income children. Birth certificates of children born in Iowa in 1999-2009 were linked to Medicaid enrollment and dental claims data in 1999-2014 and reading and math standardized school test scores for grades 2 through 11. The following oral health measures were examined: having minor dental treatments (mostly surface fillings), major dental treatments (mostly crowns and pulpotomy) or extractions, and comprehensive dental exams during the first 5 y of life. Regression models were estimated adjusting for sociodemographic factors, early infant health, and school district effects. The sample included 28,859 children and 127,464 child-grade observations. In total, 21%, 12%, and 62% of children had at least 1 minor dental treatment, 1 major treatment or extraction, and 1 comprehensive dental exam in the first 5 y of life, respectively. Children who received a minor dental treatment had higher reading and math scores by 1 percentile (95% CI, 0.09-1.9) and 0.9 percentiles (95% CI, 0.02-1.8), respectively. Children who had a major dental treatment or extraction had lower reading and math scores by 2.4 (95% CI, -3.5 to -1.4) and 1.8 (95% CI, -2.8 to -0.8) percentiles. Children who had a comprehensive oral exam had higher reading and math scores by 0.7 (95% CI, 0.06-1.4) and 1.2 (95% CI, 0.6-1.9) percentiles. The findings suggest that children's oral health before school age is associated with academic achievement later during school years.

A network psychometric validation of the Children Oral Health-Related Quality of Life (COHQoL) questionnaire among Aboriginal and/or Torres Strait Islander children

In Australia, research evidence has shown that Aboriginal and/or Torres Strait Islander children experience a higher burden of oral health diseases compared to other non-Indigenous children. The impact of oral health diseases on children's functional and psychosocial outcomes led to the development of several instruments to evaluate child oral health-related quality of life (COHQoL), such as the Parental-Caregiver Perception Questionnaire (P-CPQ) and the Family Impact Scale (FIS). However, the psychometric properties of these instruments have been evaluated only in Western cultures and have not been investigated for Aboriginal children in Australia. The current study aimed to examine the psychometric properties of the short-forms P-CPQ and FIS for Aboriginal and/or Torres Strait Islander children aged 2-3 years. Data were collected from the South Australian Aboriginal Birth Cohort (SAABC), including 270 Aboriginal children aged 2-3 years. Network psychometric models were used to investigate dimensionality, item redundancy, structural consistency and item stability, model fit, internal consistency reliability and criterion validity. We propose an instrument named Aboriginal Children's Oral Health-Related Quality of Life Questionnaire (A-COHQoL). Our findings indicated that, after the exclusion of four problematic items, the A-COHQoL showed a three-dimensional structure ("Parent/Family Activities", "COHQoL" and "Family Conflict") with good model fit and reliability. The A-COHQoL is a psychometrically robust and sensitive instrument that is readily available for Aboriginal and/or Torres Strait Islander children aged 2-3 years in Australia and can be adapted in the future for Indigenous child groups in other countries.

The prevalence of dental caries and associated factors among students living with disability in the Amhara region, Ethiopia

OBJECTIVES

People living with disability are more vulnerable to dental caries and have a high decayed, missed, and filled permanent teeth (DMFT) index and untreated dental disease than nondisabled individuals. In Ethiopia, there is a dearth of information on the oral health status of the disabled population. Hence, this study aimed to determine the prevalence of dental caries and its predictors among special needs school students in the Amhara region, Ethiopia.

METHODS

An institution-based cross-sectional study was done on special needs school students in the Amhara region from November 2020 to April 2021. The study participants were recruited using a simple random sampling technique using a computer random generator. Data collection was done using the World Health Organization oral health survey tool. Data entry was done using Epi-data 4.6 and analyzed using SPSS 26. A logistic regression model was used to identify the possible predictors of dental caries.

RESULTS

Four hundred and forty-three students with a mean age of 15.8 ± 3.8 were included in the study. The prevalence of dental caries was 41.5% (95% confidence interval [CI]: 36.3, 46.0) in permanent dentition with a mean DMFT score of 1.3 ± 1.6. The prevalence of dental caries in primary dentition was 23.1% (95% CI: 11.9, 32.1) with a mean decayed, missed, and filled primary teeth (dmft) score of 1.9 ± 0.2. Being 7-12 years old (adjusted odds ratios [AOR] = 3.6, 95% CI: 1.6, 8.3), lower grade level (AOR = 2.4, 95% CI:1.3,4.4), poor oral hygiene status (AOR = 2.5, 95% CI: 1.3, 4.8), and lack of parental support during tooth brushing (AOR = 2.2, 95% CI: 1.2, 4.1) were independent predictors of dental caries.

CONCLUSIONS

A significant amount of special needs school students in the study area had dental caries. Age, grade level, oral hygiene status, and lack of parent support during tooth brushing were independent predictors of dental caries.

Factors Associated with Pre-Dental Students' Intention and Willingness to Serve in the Underserved Community and Vulnerable Population

A potential solution to the problem of how to increase access to dental care for the underserved and vulnerable populations is to establish an early pipeline of underrepresented and minority college students for a career in dentistry. This study aims to explore factors associated with such pre-dental students' future intentions to serve. A cross-sectional design was utilized with 144 participants completing the questionnaire with four sections, including participants' demographics, experience in access to dental care, psychosocial factors, and intention to serve the underserved and vulnerable populations. Descriptive statistics, chi-squared test, and logistic regression were used for statistical analyses. A positive attitude (OR = 12.03) and higher confidence towards addressing access to dental care issues (OR = 10.43) were found to be the strongest factor for higher intention to serve the underserved and vulnerable populations. Higher knowledge on the prevalence of dental caries among children (OR = 3.18) and participants who experienced difficulty in getting a dental appointment, or finding an available dentist when needed (OR = 3.43), were also associated with higher intention. Identifying key factors associated with higher intention to serve the underserved and vulnerable populations as a future dentist may facilitate workforce recruitment in the Health Profession Shortage Areas (HPSAs).

Are oral health conditions associated with schoolchildren's performance and school attendance in the Kingdom of Bahrain? A life-course perspective

BACKGROUND

The link between oral diseases and school performance and school attendance remains unclear among Middle Eastern children.

AIM

To investigate the relationship of oral conditions with schoolchildren's school performance and attendance using the life-course approach.

DESIGN

A cross-sectional study was conducted with 466 schoolchildren aged 7-8 years from Kingdom of Bahrain (KoB) and their parents. Questionnaire data on children's current and at-birth environmental characteristics were completed by their parents. Children's oral health measures, including ICDAS (International Caries Detection and Assessment System), PUFA (pulp, ulcer, fistula, abscess), and DDE (developmental defects of enamel) indices, were the exposure variables. School performance and school attendance data obtained from the school register were the outcome variables. The data were analysed using multivariate ordinal logistic regression.

RESULTS

The odds of excellent school performance were significantly lower for children with untreated dentinal caries (OR = 0.98; 95% CI: 0.96-0.99). Children with caries-treated teeth showed greater odds of excellent school performance (OR = 1.41; 95% CI: 1.15-1.74). Disease Control and PreventionNone of the dental conditions were significantly associated with children's school attendance. A permissive parental style was associated with poor school attendance (OR = 2.63; 95% CI: 1.08-6.42).

CONCLUSION

Dental caries was associated with poor school performance but not with school attendance. Treated caries was associated with good school performance.

Clinical consequences of untreated dental caries and school performance in low-income adolescents

BACKGROUND

The possible link between dental status and school performance has been investigated. The influence of the clinical consequences of untreated dental caries in this association, however, has been minimally explored.

AIM

To assess the relationship between clinical consequences of untreated dental caries and school performance in adolescents, and to examine the demographics and socioeconomic status pathways by which clinical consequences of untreated dental caries is associated with school performance.

DESIGN

A cross-sectional study involving 363 low-income school adolescents was conducted in the city of Manaus, Brazil. Dental clinical measures were registered by five calibrated examiners to evaluate dental caries experience (decayed, missing, and filled teeth index [DMFT]) and clinical sequelae of dental caries (PUFA/pufa index). School performance was assessed using school grade history obtained from official records. Statistical analysis was conducted using pathway analysis to estimate beta coefficients (β) of the direct and indirect effects between variables.

RESULTS

DMFT and PUFA/pufa mean were 1.93 and 0.30, respectively. PUFA/pufa scores (β = -0.19) and male sex (β = 0.35) directly predicted poor school performance. DMFT was indirectly linked to poor school performance via PUFA/pufa scores (β = -0.03).

CONCLUSIONS

Dental caries and clinical consequences of dental caries were important predictors of poor school performance in low-income adolescents via direct and indirect effects.

The policy implementation gap of school oral health programmes in Tshwane, South Africa: a qualitative case study

BACKGROUND

School going children across the world continue to experience high levels of untreated dental diseases. The South African Oral Health policy documents present measures to address the oral health needs of children in school settings, yet the burden of oral disease in the country is over 50% among primary school children.

METHODS

Our study therefore sought to assess the implementation of school oral health programmes in Tshwane in line with policy recommendations using the Walt & Gilson policy analysis triangle. A qualitative explanatory case study was undertaken using a combination of data from direct observations and interviews. The case analysis involved assessing the processes of providing school oral health programmes that were offered at 10 schools in Tshwane. The measuring tools included process maps and an interview guide.

RESULTS

The results found that policy implementation was affected by poor prior planning, inadequate resources, poor school infrastructure and lack of support from key stakeholders. Furthermore, inconsistencies in policy interpretation by management, coupled with the fact that the oral hygienists were not conversant with the policy hampered delivery of the policy content. The variations in policy implementation observed were often at the discretion of the oral hygienist in response to contextual challenges.

CONCLUSION

There was policy and practice misalignment and variations in the processes of implementing oral health programmes across the 10 schools. Hence regular monitoring, evaluation and root cause analysis is recommended for such programmes in order to make informed decisions on contextually relevant and standardised programme modifications.

Senso de coerência e fatores associados ao desempenho escolar de adolescentes

Resumo O desempenho escolar é um aspecto fundamental para o futuro sucesso profissional e social. O objetivo do presente estudo foi investigar os fatores associados ao desempenho escolar dos adolescentes, incluindo o Senso de Coerência (SOC) e o estado de saúde bucal. Foram incluídos, no estudo, 381 escolares entre 15 e 18 anos de idade da cidade de Campo Grande, Mato Grosso do Sul, Brasil. O desfecho foi o desempenho escolar avaliado por meio das notas finais das disciplinas de Português e Matemática em 2013. As variáveis independentes foram dados sociodemográficos, autopercepção de saúde bucal, uso de serviços odontológicos e Senso de Coerência, obtidos por um questionário autoaplicado. Além disso, avaliou-se o número de dentes cariados, perdidos e obturados (índice de CPO-D). Análises de regressão logística foram realizadas, com base em um modelo hierárquico. A idade média dos alunos foi de 16 anos; valor médio do CPO-D 4,1 e SOC 44,5. No ajuste final, os indivíduos do sexo masculino (p = 0,0021); aqueles com o maior número de pessoas que moravam em casa (p = 0,0021) e o SOC fraco (p = 0,0005) mostraram associação com o menor desempenho escolar. Em conclusão, o desempenho escolar é um fenômeno complexo, associado ao SOC e às características bucais.

Oral health, academic performance, and school absenteeism in children and adolescents: A systematic review and meta-analysis

BACKGROUND

The authors conducted a systematic review and meta-analysis to provide a summary estimate of the association between oral health and academic performance.

TYPES OF STUDIES REVIEWED

The authors conducted a systematic search of PubMed, Embase, and Google Scholar for studies on oral health, school absence, and academic achievement published in English from January 1945 through December 2017. Exposures included subjectively or objectively measured caries, oral pain, and periodontitis. Outcomes included school absence and school achievement.

RESULTS

The authors screened a total of 2,041 studies, from which they extracted data from 14 studies of 139,989 children (12 cross-sectional studies, 1 case-control study, and 1 longitudinal study). Five studies had school absence as the primary outcome, and 7 studies had student achievement as the primary outcome. Three studies included both outcomes. The authors found no studies for periodontitis. The average modified Newcastle-Ottawa Scale score was 3.93. The authors rated 10 studies as having a low risk of bias and 4 as having a high risk of bias. Qualitative synthesis suggested that poor oral health may have negative effects on student absenteeism and achievement, but study quality was highly variable. Results from meta-analyses indicated that poor oral health was significantly associated with increased odds of poor academic performance (pooled odds ratio, 1.52; 95% confidence interval, 1.20 to 1.83) and absenteeism (pooled odds ratio, 1.43; 95% confidence interval, 1.24 to 1.63).

CONCLUSIONS AND PRACTICAL IMPLICATIONS

Increased focus on the broader implications of improvements in oral health for children, such as educational or socioemotional development, is of further interest to practicing dentists owing to the greater connection between oral health and general health. The authors of this study found that caries or tooth pain had a negative association with academic achievement and school absenteeism. However, study quality was limited by inconsistent exposure and outcome definitions and a predominance of cross-sectional designs. Thus, causal conclusions are not supported.

Does oral health influence school performance and school attendance? A systematic review and meta-analysis

AIM

To examine the evidence on the influence of oral health status on school performance and school attendance in children and adolescents.

DESIGN

A systematic review was performed in accordance with PRISMA included epidemiological studies that assessed concomitantly oral health measures, participants' school performance and/or school attendance. Electronic search was conducted on MEDLINE, SCOPUS, Web of Science, ScienceDirect, and LILACS. Studies published up to May 2018 in any language were eligible. The risk of bias was assessed using the Newcastle-Ottawa Scale. Meta-analysis was used to obtain pooled estimates between oral health measures and school performance and school attendance.

RESULTS

Eighteen studies were included. Of them, fifteen studies were used for the meta-analyses. Most studies were assessed as moderate quality. Children with one or more decayed teeth had higher probability of poor school performance (OR = 1.44 95%CI: 1.24-1.64) and poor school attendance (OR = 1.57 95%CI: 1.08-2.05) than caries-free children. Poor parent's perception of child's oral health increased the odds of worse school performance (OR = 1.51 95%CI: 1.10-1.92) and poor school attendance (OR = 1.35 95%CI: 1.14-1.57).

CONCLUSIONS

Children and adolescents with dental caries and those reporting worse oral health experience poor school performance and poor school attendance.

Silver diamine fluoride versus therapeutic sealants for the arrest and prevention of dental caries in low-income minority children: study protocol for a cluster randomized controlled trial

BACKGROUND

Dental caries is the most prominent childhood disease in the world. In the United States, more than 50% of children have experienced caries. Untreated caries can have negative impacts on quality of life, academic performance, and school attendance. To reduce oral health disparities, multiple organizations recommend school-based caries prevention.

METHODS/DESIGN

A longitudinal, cluster randomized, non-inferiority trial will be conducted in low-income children from primarily Hispanic/Latino backgrounds currently enrolled in public elementary schools in New York City, New York, United States, from 2018 to 2023. The primary objective is to compare the non-inferiority of silver diamine fluoride and fluoride varnish versus glass ionomer therapeutic sealants and fluoride varnish in the arrest and prevention of dental caries. Secondary objectives are to evaluate differences in effectiveness when care is provided by nurses versus dental hygienists and assess the impact of prevention on oral health-related quality of life and educational outcomes. Caries arrest will be evaluated after 2 years, and caries prevention and secondary outcomes will be assessed at the completion of the study. Data analysis will follow intent-to-treat, and statistical analyses will be conducted using a two-sided significance level of 0.05.

DISCUSSION

The comparative effectiveness of alternative caries prevention delivery models is considered to be one of the highest research priorities in the United States. Many treatments are currently available to prevent and arrest dental caries. The simplicity and affordability of silver diamine fluoride may be a viable alternative for the prevention of dental caries in high-risk children.

Assessment of oral health-related quality of life in 9-15 year old children with visual impairment in Uttarakhand, India

BACKGROUND

To assess the prevalence of dental diseases among 9-15-year-old visually impaired children and find out its impact on their daily activities using the Child-Oral Impact on Daily Performance (C-OIDP) questionnaire in districts of Uttarakhand, India.

MATERIALS AND METHODS

A total of 423 visually impaired institutionalized children between the age group of 9-15 years were included in the study. Stratified random sampling technique was used to obtain the study population. Dental caries was recorded using dmft for primary dentition and DMFT for permanent dentition, traumatic dental injuries were assessed using traumatic dental injury index, and dentofacial anomalies were recorded using Angle's classification of malocclusion. The Hindi braille version of C-OIDP questionnaire was used to gather information regarding oral health-related quality of life (OHRQoL).

RESULTS

There was a high dental caries prevalence of 57.7% in visually impaired children. The prevalence of traumatic dental injuries was 50.6%. Crowding (61.5%) was the most commonly seen dentofacial anomaly and the most commonly perceived oral health problem was toothache. There was less favorable OHRQoL in males as compared to females.

CONCLUSION

There was a high prevalence of dental diseases in this group and higher C-OIDP scores suggestive of unfavorable OHRQoL.

Social inequality in dental caries and changes over time among Indigenous and non-Indigenous Australian children

OBJECTIVE

This paper describes and compares magnitudes of socioeconomic (SES) inequalities in oral health among Indigenous and non-Indigenous children over a 10-year period.

METHODS

We analysed annual oral health survey data from NSW, NT and SA. Data were extracted for time period 1 (2000-2002, N=215,317) and time period 2 (2007-2010, N=34,495). Oral health outcomes were untreated decayed deciduous teeth (dt) and cumulative dental caries experience (dmft). Postcode-level Socioeconomic Index for Areas was used to assess SES. Age standardisation and complex survey weights were used. Indices of socioeconomic inequality in health (Slope Index of Inequality, Relative Index of Inequality, Absolute and Relative Concentration Index) were used to quantify inequality in dental caries and its changes over time.

RESULTS

Oral health outcomes deteriorated in both Indigenous and non-Indigenous populations over time. Indigenous children experienced higher levels of disease at both times. Untreated dt increased in both populations. The cummulative disease (dmft) increased at higher rate among children in low-SES areas in both populations. Over time, there was an increase in socioecononomic inequalities in dmft in all children and in dt in non-Indigenous children.

CONCLUSION

Area-level socioeconomic inequality in child oral health has widened due to deterioration in low-SES children.
