Association between Traumatic Dental Injury, Obesity, and Socioeconomic Status in 6- and 13-Year-Old Schoolchildren

Possible Risk Factors for Dental Fear and Anxiety in Children Who Suffered Traumatic Dental Injury

BACKGROUND

Children who undergo painful experiences such as traumatic dental injury (TDI) during their early years are more likely to be at an increased risk of developing dental fear and anxiety (DFA). The purpose of this study was to identify potential risk factors for DFA of these children.

METHODS

The study participants were 220 parents/caregivers and their children who experienced TDI. Their socio-demographic backgrounds were investigated with the modified WHO Oral Health Questionnaire for Children that included questions about parents' knowledge and attitudes, while the DFA level was determined using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) and the Simplified Oral Hygiene Index (OHI-S Index) was used to assess oral hygiene status.

RESULTS

The confirmed risk factors are parental knowledge, female gender, and degree of oral hygiene and pain in the last three months, while age, type of TDI, presence of soft-tissue injury, and number of subjective complaints were not confirmed. The overall model predicted approximately 54% of variance in DFA, R2 = 0.545, F (4.215) = 64.28 p < 0.001.

CONCLUSIONS

These findings emphasise the importance of addressing pain management, improving oral hygiene, and enhancing parental knowledge to mitigate DFA in children with TDIs.

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.

Lip incompetence and traumatic dental injuries: a systematic review and meta-analysis

Background/aim Traumatic dental injury is an impact injury to the teeth and/or other hard and soft tissues severity of which can lead to pain, as well as aesthetic, psychological, behavioural and functional problems among children. Lip incompetence directly exposes teeth increasing the risk of traumatic dental injuries. This review aimed to assess the existing evidence regarding association of lip incompetence and dental trauma.Methods The review protocol was registered with PROSPERO with Protocol number: CRD42020163069. Electronic searches of grey literature and three databases were performed. Cross sectional studies conducted between the years 2009-2019 on children aged 0-15 years were selected. Studies were evaluated with the help of NIH quality assessment scale. Data on research question, study population, inclusion and exclusion criteria, sample size justification, exposure and outcome clearly defined and adjustment for confounding variables were assessed. All analyses were performed using Review Manager 5.4.Results The study identified 10,223 articles, 33 were included. Among these 20 identified articles reported 'Good' quality with 13 studies reporting 'Fair' quality post assessment. Subject with lip incompetence were at 2.44 (1.59-3.75) times the risk of developing traumatic injuries during primary dentition. This risk increases to 3.26 (2.21;4.53) times in mixed and permanent dentition. At 12 years of age the OR for dental trauma is 3.77 (2.06;6.91) in subjects with incompetent lips.Conclusions The results confirm the association between lip incompetence and dental trauma.

Association between obesity and traumatic dental injuries in pre-school children-A case-control study

BACKGROUND/AIM

Obese children are more prone to accidents due to poorer motor skills which increase the likelihood of falls and the occurrence of traumatic dental injuries (TDIs). The aim of this study was to determine the association between overweight/obesity and TDI in pre-school children.

MATERIAL AND METHODS

The case group was formed by children with TDI identified during a clinical examination (n = 262). Each pre-school child identified as a case was matched by a peer of the same age, gender and pre-school but without TDI to form the control group (n = 262). TDI was evaluated using the criteria proposed by Andreasen. The weight and height of the children were measured for the calculation of the body mass index which was plotted on the growth curve established by the World Health Organization. Socio-demographic variables were collected through questionnaires sent to the parents/guardians. Data analysis involved the determination of frequency distribution, the chi-square test and logistic regression analysis.

RESULTS

The sample was composed of 253 children in each group. Among the children in the case group, 15.4% (n = 39) were overweight and 15.8% (n = 40) were obese. In the control group, 13.8% (n = 35) were overweight and 8.3% (n = 21) were obese. Children with trauma were more likely to be obese than children without trauma (OR = 2.05; 95%CI: 1.14 to 3.67; p = .016). In contrast, TDI was not associated with being overweight. A greater odds of TDI was also associated with an open bite (OR = 3.61; 95% CI: 1.64 to 7.96; p = .001) and accentuated overjet (OR = 2.19; 95% CI: 1.37 to 3.50; p = .001).

CONCLUSIONS

Pre-school children with a history of dental trauma were more likely to be obese than those without a history of dental trauma whereas being overweight was not associated with TDI.

Traumatic dental injuries in special health care needs children and association with obesity

BACKGROUND

Special needs children are at a higher risk of dental trauma because of neurological, physical, mental, and behavioral impairments. They are also at higher risk of developing obesity due to the side effects of medication.

OBJECTIVE

Assess the association between traumatic dental injuries (TDIs) and obesity in children with special health care needs.

DESIGN

Analytical cross-sectional study.

SETTING

Schools for special needs children.

STUDY POPULATION AND METHODS

Special needs children with a diagnosis of TDI according to the Andreasen criteria were included in the study. Data on the disability status were obtained from a national demographic survey in 2016. Demographic and dental variables were measured for analysis. Multivariable logistic regression was used to analyse any relationship between TDI prevalence and obesity.

MAIN OUTCOME MEASURE

Relationship of body mass index (BMI) to TDI prevalence.

SAMPLE SIZE

350 (131 boys and 219 girls) special needs children with a median (interquartile range) age of 12.0 (2.0) years.

RESULTS

Eighty-one (23.1%) children presented with TDIs. The mean (standard deviation) BMI for the entire study population was 24.7 (7.8). Children with obesity had a 30.3% TDI prevalence compared normal-weight children (20.6%) (P=.035), but BMI category was not statistically significant in the regression analysis (P=.541), which showed that children with an overjet of >3 mm were 4.82 times (CI: 2.55-9.09, P=.001) more likely to have TDI than children with an overjet of ≤3 mm. Those with inadequate lip coverage were 2.85 times (CI: 1.49-5.44, P=.002) more likely to have TDI. Children with cerebral palsy were 3.18 times (CI: 1.89-11.32, P=.024) more likely to have TDI than children with other disabilities.

CONCLUSION

The study showed a significant association between TDI prevalence and increased overjet, inadequate lip coverage, and cerebral palsy. The prevalence of TDI among obese special needs children was statistically significant according to bivariate analysis, but not in a multivariate analysis that adjusted for other variables.

LIMITATIONS

Causal relationship cannot be established with cross-sectional study.

CONFLICT OF INTEREST

None.

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.

Childhood unintentional injury: The impact of family income, education level, occupation status, and other measures of socioeconomic status. A systematic review

Introduction

Unintentional injuries represent a substantial public health burden among children and adolescents, and previous evidence suggests that there are disparities in injury by socioeconomic status (SES). This paper reports on a systematic review of literature on injury rates among children and adolescents by measures of SES.

Methods

A systematic literature search was conducted using six electronic databases: MEDLINE, PsycINFO, CINAHL, HealthSTAR, EMBASE, and SportsDiscus. This review considered children ages 19 years and under and publications between 1997 and 2017-representing an update since the last systematic review examined this specific question. Fifty-four articles were summarized based on study and participant descriptions, outcome and exposure, statistical tests used, effect estimates, and overall significance.

Results

Most articles addressed risk factors across all injury mechanisms; however, some focused particularly on burns/scalds, road traffic injuries, falls/drowning cases, and playground/sports injuries. Other studies reported on specific injury types including traumatic dental injuries, traumatic brain injuries, and fractures. The studies were of moderate quality, with a median of 15.5 (95% confidence interval [CI]: 15.34 to 15.66) out of 19. Thirty-two studies found an inverse association between SES and childhood unintentional injury, three found a positive association while twenty were not significant or failed to report effect measures.

Conclusion

Given the variability in definition of the exposure (SES) and outcome (injury), the results of this review were mixed; however, the majority of studies supported a relationship between low SES and increased injury risk. Public health practice must consider SES, and other measures of health equity, in childhood injury prevention programming, and policy.

A systematic review and meta-analysis estimating the population prevalence of comorbidities in children and adolescents aged 5 to 18 years

Evidence for the health impact of obesity has largely focussed on adults. We estimated the population prevalence and prevalence ratio of obesity-associated comorbidities in children and adolescents aged 5 to 18 years. Five databases were searched from inception to 14 January 2018. Population-based observational studies reporting comorbidity prevalence by weight category (healthy weight/overweight/obese) in children and adolescents aged 5 to 18 years from any country were eligible. Comorbidity prevalence, stratified by weight category, was extracted and prevalence ratios (relative to healthy weight) estimated using random effects meta-analyses. Of 9183 abstracts, 52 eligible studies (1 553 683 participants) reported prevalence of eight comorbidities or risk markers including diabetes and nonalcoholic fatty liver disease (NAFLD). Evidence for psychological comorbidities was lacking. Meta-analyses suggested prevalence ratio for prediabetes (fasting glucose ≥ 100 mg/dL) for those with obesity relative to those of a healthy weight was 1.4 (95% confidence interval [CI], 1.2-1.6) and for NAFLD 26.1 (9.4-72.3). In the general population, children and adolescents with overweight/obesity have a higher prevalence of comorbidities relative to those of a healthy weight. This review provides clinicians with information when assessing children and researchers a foundation upon which to build a comprehensive dataset to understand the health consequences of childhood obesity.

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.

Are traumatic dental injuries greater in alcohol or illicit drugs consumers? A systematic review and meta-analysis

INTRODUCTION AND AIMS

Traumatic dental injuries (TDI), alcohol and illicit drugs consumption are highly-prevalent public health concerns. The aim of this study was to evaluate the association between alcohol and/or illicit drugs consumption and the presence of TDI.

DESIGN AND METHODS

This review was performed in accordance with MOOSE and PRISMA guidelines. Electronic searches were performed to found observational studies that investigated subjects that consumed alcohol and/or illicit drugs associated with TDI. Data extraction and a risk of bias assessment were performed. Three meta-analyses (MA) were performed to evaluate the association between TDI and alcohol consumption (1^stMA), subgrouping the studies into alcohol intake and binge-drinking, alcohol-related problems (2^ndMA), and drugs (3^rdMA). The odds ratio (OR) were calculated (p ≤ 0.05) for all analyses. The evidence was certainty-tested using the GRADE approach.

RESULTS

Twelve articles met the eligibility criteria. Nine studies were methodologically sound, while three had some confounding factors. In the pooled MA, an association between alcohol consumption and TDI (OR 1.57[1.33,1.85],p = 0.00001) was determined with moderate certainty of evidence, confirmed in the subgroups of alcohol intake (OR 1.49[1.17,1.90],p = 0.001) and binge-drinking (OR 1.68[1.30,2.18],p = 0.0001). No associations were found between TDI and risk for alcohol-related problems and drug use (OR 0.75[0.50,1.14],p = 0.18, and OR 1.20[0.82,1.75],p = 0.27, respectively), with both analyses having a very low certainty of evidence.

DISCUSSION AND CONCLUSIONS

There is moderate evidence concerning the association between alcohol use and TDI. Despite the absence of an association between illicit drugs use, alcohol-related problems and the presence of TDI, these results should be viewed with caution, since they had very low-certainly-evidence.

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.

High weight standard and removal of third molars: a prospective randomized study

OBJECTIVE

Compare the degree of exposure to adverse events during the removal of third molars between 2 groups of patients.

STUDY DESIGN

Researchers designed and implemented a prospective randomized study. The study consisted of overweight and normal-weight patients subjected to the surgical removal of impacted lower third molars. A wide range of predictor variables was registered in the preoperative phase. Statistical calculations were computed.

RESULTS

Five hundred sixty surgeries were performed involving 2 groups (1:1). Adverse events were found in 29.3% of surgeries in overweight patients. The same procedures performed on normal-weight patients resulted in a complication rate of 10.7%. Predictor variables significant to these events were detected.

CONCLUSIONS

Overweight patients have 3 times greater risk of experiencing morbidities during the removal of lower third molars compared with patients of normal weight. Our findings have important implications for public health, given the exorbitant growth in the population of patients with high standard weight.
