Association of traumatic dental injuries with individual-, sociodemographic- and school-related factors among schoolchildren in midwest Brazil

Association between socioeconomic status and traumatic dental injury in permanent teeth: A systematic review with meta-analysis

OBJECTIVE

The aim of this study was to systematically review observational studies assessing the association between socioeconomic status (SES) and traumatic dental injuries (TDI) in permanent dentition.

METHODS

Electronic searches were performed in PubMed, EMBASE, Web of Science, LILACS, CINAHL, COCHANE Library and ScoINDEX databases for articles published up to February 2023. Two independent reviewers performed the search and critical appraisal of the studies. The inclusion criteria were observational studies that evaluated the association between individual-level socioeconomic indicators and TDI (clinically examined) in permanent teeth. Quality assessment of included articles was conducted using the Newcastle-Ottawa Scale. Global meta-analysis was performed with all studies and different subgroup analysis based on socioeconomic indicators (household income, educational level or any other indicator), age (children, early adolescents, late adolescents or young adults) and economic classification of the country (high, upper-middle or lower-middle). A random-effects model was used to estimate pooled prevalence ratios (PR) and respective 95% confidence intervals (CI) for each study.

RESULTS

The search strategy retrieved 11 315 publications. According to eligibility criteria, 17 articles were included in the meta-analysis. Individuals with low SES were 17% more likely to have TDI (PR 1.17; 95% CI 1.05-1.30). The subgroup analysis also revealed that the indicator (household income, PR 1.16; 95% CI 1.00-1.34) and the economic classification of the country (upper-middle, PR 1.19; 95% CI 1.07-1.33) influenced the association of SES with TDI occurrence.

CONCLUSIONS

Individuals with lower SES were more likely to present with TDI in permanent dentition than those with higher SES.

Contextual and individual factors associated with traumatic dental injuries in deprived 12-year-old schoolchildren: A cohort study

AIM

Traumatic dental injuries (TDIs) among children and adolescents have been acknowledged as of public health concern worldwide. The aim of the study was to assess the relationship between contextual and individual characteristics and TDIs in 12-year-old schoolchildren.

MATERIALS AND METHODS

A cohort study was conducted with 355 schoolchildren living in deprived communities in the city of Manaus, Brazil. Contextual factors (place of residence and socio-economic indicators) and individual characteristics, including sex, family income, parents/guardians years of schooling, overjet and open bite (Dental Aesthetic Index), self-esteem (Rosenberg Self-Esteem Scale), sense of coherence (Sense of Coherence Scale), oral health beliefs, social support (Social Support Appraisals) were assessed at baseline. TDIs were measured at baseline and at 2-year follow-up using the O'Brien Index. Data were analysed through confirmatory factor analysis and structural equation modeling.

RESULTS

The baseline prevalence of TDIs was 17.6% and the incidence of TDIs at 2-year follow-up was 26.8%. Better psychosocial status had a direct protective effect on the incidence of TDIs (β = -.184). Better contextual characteristics (β = -.135) and greater overjet (β = -.203) were directly associated with poor psychosocial status. Higher schooling of parents/guardians directly predicted better psychosocial status (β = .154). Psychosocial status mediated the relationship of greater overjet (β = .036), contextual factors (β = .024) and parental/guardian schooling (β = -.027) with TDIs.

CONCLUSIONS

Contextual factors and individual characteristics predicted TDIs. Psychosocial status was a relevant individual attribute in the causal network of TDIs, due to the direct effect on the incidence of TDIs as well as a mediator on the influence of contextual factors, overjet and parents/guardians schooling on the incidence of TDIs.

Critical appraisal of confounding factors of observational studies on the association between dentofacial features and dental trauma in a Brazilian population

AIMS/OBJECTIVES

Dental trauma is a highly prevalent dental emergency. Children and adolescents without inadequate lip coverage, increased overjet, and anterior open bite are associated with the occurrence of traumatic dental injuries. Observational studies do not allow the inference of causality, one of the reasons being: the potential confounding factors. Therefore, this review aimed to critically appraise the confounding factors considered in epidemiological studies that associate dentofacial features with the occurrence of dental trauma in Brazilian children and adolescents.

METHODS

Studies included in the qualitative synthesis of a recently published comprehensive systematic review and meta-analysis on the topic were screened. Studies that only mentioned the performance of bivariate analyzes or that did not mention the performance of multivariate analyzes were excluded. Evaluation of control statements for possible confounders and bias consideration was performed for each selected study. Confounding factors in these studies were also identified and categorized according to their domains.

RESULTS

Fifty-five observational studies were screened, of which 11 were excluded due to the mention of only bivariate analyzes or the lack of multivariate analyses. The remaining 44 studies were critically appraised. Of these, 9 studies specifically mentioned the term confounding, and 12 studies mentioned the term bias. However, only 14 studies mentioned limitations on confounding factors in their findings. Among the 99 different variables identified, the most used were type of trauma, followed by sex and age.

CONCLUSION

Most studies did not acknowledge the control for possible confounding factors and rarely stressed the need for caution in interpreting their results. Cross-sectional studies do not allow inferring a cause-and-effect relationship between dentofacial features and dental trauma.

Dental trauma and oral health-related quality of life among 7th-grade students of public elementary schools

Dental trauma is a public health problem because of its high prevalence rates and treatment costs and for affecting mainly younger individuals. Aim: This cross-sectional study aimed to investigate the variables associated with dental trauma and its influence on oral health-related quality of life among 7th-grade students of public elementary schools. Methods: The data was collected with semi-structured and self-administered questionnaires and an intraoral clinical examination (n = 204). The variables collected regarded dental trauma, lip coverage, overjet, oral health-related quality of life (Child Perceptions Questionnaire - CPQ11-14 ISF: 8), and sociodemographic profile. Association tests and the Mann-Whitney test were performed at a 5% significance level. Results: Dental trauma occurred in 12.3% of students, 94.6% had adequate lip coverage, and the mean overjet was 2.7 mm (±2.0). Sex was the only variable with a statistically significant association with dental trauma (p = 0.021). There was no statistically significant difference in the CPQ11-14 ISF: 8 score between students with and without dental trauma (p = 0.136). Conclusions: Dental trauma was significantly associated with sex and did not impact the oral health-related quality of life of the students.

Association between Western Australian children

ObjectiveThis study investigated the link between socioeconomic status and unplanned dental presentations at the Perth Children's Hospital (PCH), as well as the link between the socioeconomic status of unplanned dental patients and any previous admissions to the PCH.MethodsRecords of 351 unplanned visits to the PCH were collected, including reason for attendance (infection, trauma, other), the patient's residential location (suburb) and the history of any previous presentations at the PCH. The socioeconomic status of each patient was based on the Index of Relative Socio-Economic Disadvantage, divided into quintiles. Geographic information systems (GIS) were used to spatially map the residential locations of the patients with unplanned dental presentations. QGIS was used to map and geocode the data. Analysis of variance and Chi-squared tests were used to determine associations between subgroups and other variables.Results'Unplanned dental presentation' in this study refers to patients who present without an appointment, including by referral from the emergency department of the PCH or outside the PCH. Approximately two-thirds of unplanned dental presentation among patients from low socioeconomic groups were for dental infection, whereas the major reason for presentation among patients from higher socioeconomic groups was trauma. More than half the patients in low socioeconomic groups had at least one previous presentation at the PCH due to other medical issues.ConclusionChildren from low socioeconomic groups, or from outside of Perth, were more likely to present with dental infections, which are mostly preventable at the primary care level; these patients often presented a more significant burden to the health system. Public health interventions should aim to promote preventive oral health care, especially for children from low socioeconomic groups.What is known about the topic?In Western Australia, the most common dental problems requiring hospitalisation among children is dental caries, and children from the lowest socioeconomic backgrounds have the highest prevalence of dental hospitalisations.What does this paper add?Children from lower socioeconomic backgrounds were more likely to have an unplanned presentation at the only tertiary children's hospital in Western Australia due to dental infection.What are the implications for practitioners?Improved access to public dental services, especially in low socioeconomic areas, and the development of more strategies to reduce unplanned dental presentations at a tertiary hospital are needed.

Prevalence of dental trauma in Brazilian children and adolescents: a systematic review and meta-analysis

This study aimed to investigate the prevalence of dental trauma in Brazilian children and adolescents. A systematic review was conducted considering eight databases: MEDLINE (via PubMed), LILACS, BBO, Scopus, Embase, Web of Science, Open Access Theses and Dissertations, and OpenThesis. Only prevalence studies that used a probabilistic sampling method were included, without restriction on year or language of publication. The JBI critical appraisal tools for prevalence studies were used to assess the individual risk of bias. The individual studies were combined in the meta-analysis using the random-effects model. The heterogeneity between the studies was analyzed by Cochran's Q and the I-square statistics. A meta-regression analysis was performed to evaluate the sources of heterogeneity. The GRADE approach assessed the certainty of evidence across included studies. The search resulted in 2,069 records, of which 36 were included in the study. The eligible studies were published from 2000 to 2021, with a total sample of 40,194 children and adolescents. Most studies (75%) had a low risk of bias. In permanent teeth, the prevalence of dental trauma was 21% (95%CI: 16.0; 26.0) and in deciduous teeth; 35% (95%CI: 26.0; 44.0). The prevalence of dental trauma among boys was higher than among girls for both dentitions. Based on a low certainty, the prevalence of traumatic dental injuries in Brazilian children and adolescents is higher than that found worldwide both in deciduous and permanent teeth. Also, the prevalence of dental trauma among boys is higher than among girls.

The association of inadequate lip coverage and malocclusion with dental trauma in Brazilian children and adolescents - A systematic review and meta-analysis

BACKGROUND/AIM

Dental trauma (DT) occurs frequently in children and adolescents. Therefore, understanding the factors associated with its occurrence in these age groups is important to establish specific preventive measures. The aim of this study was to investigate the relationships of lip coverage, overjet, and open bite to dental trauma in Brazilian children and adolescents.

MATERIAL AND METHODS

The review protocol was registered in the PROSPERO database (CRD42020156290) and the bibliographic search was performed in nine electronic databases until July 2020. The studies included were observational, performed in Brazil, with healthy children and adolescents (0-19 years old), and without the restriction of date or language. Two reviewers assessed the individual risk of bias of the eligible studies with a standardized checklist. The meta-analyses were stratified by dentition stage and age range using fixed or random effects, odds ratio (OR) as the effect measure, and 95% confidence interval. The heterogeneity across studies was assessed with the I² test and the GRADE approach assessed the certainty of evidence.

RESULTS

The search presented 2493 initial results, from which 55 met the eligibility criteria and were included. Most studies (67%) presented a low risk of bias and were published between 2000 and 2019. Children and adolescents with inadequate lip coverage are 1.86-2.36 times more likely to suffer from DT, while those with increased overjet are 1.94-3.11 times more likely. Children with primary dentitions and anterior open bites are 1.76 (95% CI: 1.20-2.59) times more likely to suffer from DT. The certainty of evidence varied from very low to moderate.

CONCLUSIONS

Inadequate lip coverage, increased overjet, and anterior open bite are associated with the occurrence of dental trauma in Brazilian children and adolescents.

Spatial density of adolescents aged 14 years old, victims of dental: A longitudinal study

BACKGROUND/AIM

Knowledge about the spatial density of the domiciles of dental trauma victims can assist in the identification of the most vulnerable areas and contribute to the planning of prevention, promotion, control, and treatment actions, focusing on the most affected areas. The aim of this study was to analyze the spatial density of domiciles of 14-year-old adolescent victims of dental trauma, in the city of Diamantina, Brazil, after a two-year follow-up period.

MATERIAL AND METHODS

This longitudinal study was carried out with 584 adolescents between 2013 and 2015. Dental trauma, overjet, and lip protection were assessed by two trained and calibrated examiners (K > 0.70). Information about binge drinking was collected among the adolescents through the Alcohol Use Disorders Identification Test and sociodemographic indicators were obtained through a questionnaire answered by the caregivers of the adolescents. Spatial analyses were performed to evaluate the spatial density of adolescents with dental trauma and the independent variables of interest according to the domicile using Ripley's K function and the Kernel Map.

RESULTS

Ripley's K function revealed spatial aggregation of the domiciles of adolescent victims of dental trauma in relation to males, binge drinking and overjet, with a confidence interval of 95%. The higher density of domiciles with adolescents with two or more traumatized teeth was found in the north-east region of the city. Boys were the most affected, their homes were located in the north, north-west, and south-east regions at baseline and follow-up. The largest density of domiciles of adolescents with overjet greater than 5 mm and inadequate lip protection was in the north-east region. Similar spatial distribution was identified for binge drinking for both years.

CONCLUSION

The majority of adolescents with dental trauma lived in the north-east and south-east regions, characterized by high population density and greater social vulnerability.

Traumatic dental injuries in the Eastern Region of Saudi Arabia: Factors influencing teachers' management practices

BACKGROUND/AIMS

Traumatic dental injuries (TDIs) in children frequently occur in schools where teachers can play an important role in their management. Therefore, the aim of this study was to assess schoolteachers' knowledge and the factors that determine their management of TDIs.

MATERIALS AND METHODS

This cross-sectional study was conducted in the Eastern Province of Saudi Arabia from January to June 2018. Data were collected through an online pre-tested questionnaire. The questionnaire collected demographic data and included questions that assessed participants' knowledge and management practices for TDI. Chi-square test and multivariate logistic regression analysis were performed.

RESULTS

A total of 443 teachers were included in the study, and 72.5% of the participants were females. The prevalence of TDIs was 49% yet only 7.2% of the participants reported managing dental trauma. Fights (22.8%) and falls (21.7%) were the most common causes of dental injuries. Mean TDI knowledge score was 2.75 ± 2.05, but only 47.2% were willing to receive training about TDI management. Regarding supportive environments, 75.8% of teachers reported having safety playgrounds, however 10.6% reported having a nurse in schools. After controlling for other variables, male respondents were 3.85 times more likely to manage TDIs than female respondents (P = .001). Similarly, previous knowledge of dental trauma management (OR = 4.32, P < .001) and having less than 50 students in class (OR = 2.61, P = .021) were significantly associated with TDI management.

CONCLUSION

The teachers demonstrated inadequate knowledge about TDIs which were highly prevalent in primary schools. Male gender, having knowledge of TDI management and teaching less students were associated with increased likelihood of TDI management. There is a crucial need for the reinforcement of policies that support school safety and a supportive environment.

Prevalence of traumatic crown injuries in German adolescents

OBJECTIVES

Although dental trauma and its unfavorable sequelae are considered major public health problems worldwide, the published data on the prevalence of traumatic crown injuries (TCIs) in Germany are lacking. Therefore, the present study assessed the prevalence of TCIs among adolescents in Bavaria, Germany.

MATERIAL AND METHODS

Ethical approval and parental consents were obtained, and population-based information from 10- (N = 1158), 12- (N = 416), and 15-year-olds (N = 1302) from two different cohort studies performed in Bavaria (GINIplus/LISA and LAGZ) were examined for the presence of TCIs, dental caries, and restorations. Statistical comparisons were made using Mann-Whitney U test and Wilcoxon signed-rank test.

RESULTS

The prevalence of TCIs was 6.3% in the 10- and 12-year-old children and 14.0% in 15-year-old children, and a higher prevalence was observed in boys than in girls. Most (87.5%) of the traumatized teeth were maxillary incisors. The caries prevalence was low in all three populations.

CONCLUSION

The prevalence of TCIs in Bavarian adolescents at a low risk for caries was found to be low.

CLINICAL RELEVANCE

Dental trauma is a prevalent event in children and adolescents, and incisors are the most affected teeth. Therefore, dental practitioners should be able to manage the spectrum of traumatic injuries.

[Outcomes of traumatic dental injuries in children]

The aim of the study was to review literature data on incidence and outcomes of traumatic dental injuries (TDI) in pediatric population. A systematic search was conducted using Elibray, Pubmed/Medline, Scopus databases in October 2018. Reference lists were also hand-searched to identify additional literature. The most prevalent complication of TDI is pulp necrosis (PN) which triggers inflammatory root resorption (IRR). PN and IRR are however much more specific for mature permanent teeth. In immature teeth pulp revascularization may occur even after avulsion. Pulpectomy timing is well defined for mature teeth only. It is accepted that pulp extirpation should be performed in the first 10 days after trauma. In immature teeth no criteria exist with pulp electrosensitivity having very low negative prognostic value as drop of pulp sensitivity because of trauma not necessary indicate PN. Follow-up protocol for immature teeth with various TDI would be useful for proper timing of pulpectomy and prevention of IRR.

World traumatic dental injury prevalence and incidence, a meta-analysis-One billion living people have had traumatic dental injuries

Traumatic dental injuries (TDIs) account for a considerable proportion of bodily injuries. Nevertheless, global TDI frequency is unknown, probably because TDI diagnosis is not standardized. This study estimated world TDI frequency. A literature search (publication years 1996-2016) was aimed at covering as many countries, communities, ethnic groups as possible, thus achieving high generalizability. In particular, non-specific keywords, no language restrictions, and large databanks were used. Observational studies reporting proportions of individuals with at least one TDI (prevalence) and who developed TDI (incidence rate) were considered. Prevalence rates to permanent dentition, primary dentition and in 12-year-olds, incidence rate to any tooth for any age, male-to-female prevalence ratio (PR) in 12-year-olds, with 95% confidence intervals (95 CIs), were extracted/calculated. Study quality, Z-score distribution, funnel plot symmetry analysis, between-study heterogeneity, sensitivity, and subgroup analyses were performed. Selected primary studies were 102 (permanent dentition; 268 755 individuals; median age, 13.8 years), 46 (primary dentition; 59 436 individuals; median age, 3.4 years), 42 (12-year-olds; 33 829 individuals), 11 (incidence rate; 233 480 person-years; median age, 7.8 years), and 31 (PR; 16 003 males, 16 006 females). World TDI frequency resulted as follows: permanent dentition prevalence 15.2% (95 CI, 13.0%-17.4%); primary dentition prevalence 22.7% (95 CI, 17.3%-28.7%); 12-year-olds prevalence 18.1% (95 CI, 15.3%-21.0%); incidence rate, 2.82 (95 CI, 2.28%-3.42%) per 100 person-years; PR, 1.43 (95 CI, 1.34%-1.52%). Differences between WHO Regions were found. This study shows that more than one billion living people have had TDI. TDI is a neglected condition which could rank fifth if it was included in the list of the world's most frequent acute/chronic diseases and injuries.

Income inequality and traumatic dental injuries in 12-year-old children: A multilevel analysis

BACKGROUND/AIM

Contextual socio-economic factors have been associated with traumatic dental injuries (TDIs). However, evidence concerning the role of income inequality on TDIs in children is scarce. The aim of this study was to investigate the association between contextual income inequality over a 10-year period and TDIs in Brazilian children.

SUBJECTS AND METHODS

The study population comprised a representative sample of 5027 children aged 12 years who participated in the Brazilian oral health survey in 2010. City-level Gini Index was used to measure contextual income inequality in the years 2000 and 2010, as well as the variation in income inequality between 2000 and 2010. Covariates were gender, ethnicity, family income, number of people per room and incisal overjet. Clinical examinations were used to assess TDIs. Multivariable multilevel ordered multinomial logistic regression was used to estimate cumulative Odds Ratio (OR) and 95% confidence intervals between income inequality and TDIs.

RESULTS

The prevalence of children who had one tooth with TDI and two or more teeth with TDIs was 15.2% and 6.4%, respectively. The maxillary central and left lateral incisors were the teeth most affected by TDIs. Gini coefficient reduction between the years 2000 and 2010 decreased the odds of TDIs even after adjustment for demographic and socio-economic characteristics, and incisal overjet. The likelihood of more TDIs decreased 21% for each 0.05 unit decrease in the Gini coefficient between the years 2000 and 2010. Boys, brown skin colour, overcrowding and incisal overjet greater than 5 mm remained statistically associated with TDIs in the final model.

CONCLUSIONS

The decrease in income inequality over a 10-year period was inversely associated with TDIs among Brazilian children aged 12 years.

Prevalence and family structures related factors associated with crown trauma in school children resident in suburban Nigeria

BACKGROUND

Multiple risk factors have been identified for traumatic dental injuries, including crown fractures, in various age groups and various populations. The objective of this study was to determine the prevalence, risk factors and family related factors for crown trauma among 8 to 16 year-old children in a suburban population, Nigeria.

METHODS

This is a secondary analysis of a data of 2107 children collected through a school-based survey. Study participants were 8 to 16 year-old resident in suburban Nigeria. The independent variables for the study were age, sex, socioeconomic status, and birth rank, family size and parenting status (one parent, step parent, both parents, and guardians). Details were collected using an interviewer administered questionnaire. Intraoral examination was conducted to identify presence of crown fracture. The independent variables associated with and predictors of crown trauma were determinedusing chi-square and logistic regression analysis respectively.

RESULTS

Only 167 (7.9 %) of the 2107 study participants had crown trauma. The teeth level prevalence of crown trauma was 0.33 %. Children with middle socioeconomic status had reduced odds of having crown trauma when compared with children with low socioeconomic status (AOR 0.50; CI 0.32-0.80). The odds of having crown traumawas more than doubled in males when compared with females (AOR 2.41; CI 1.72-3.39) and almost doubled in children living with single parents when compared with children living with both parents (AOR 1.94; CI 1.29-3.05).

CONCLUSIONS

The prevalence of crown traumawas low in this study population. Being a female and having lowsocioeconomic status significantly reduced the risk factors for crown traumawhile living with single parents increased risk for crown trauma.
