Background/aim: Children with excess weight may be more predisposed to traumatic dental injuries (TDI). The aim of this study was to investigate the association between overweight/obesity and TDI presence and severity in Brazilian preschool children., Material and Methods: A cross-sectional study was conducted of 347 children aged three to five years. The main exposure was evaluated based on the body mass index (BMI). Socioeconomic-demographic characteristics and harmful oral habits were investigated using a questionnaire sent to the parents/guardians. Oral clinical examinations were performed to determine overjet (criteria proposed by Foster and Hamilton), and the presence and severity of TDI (criteria proposed by Andreassen). Descriptive statistics were performed. Univariate and multivariate Poisson regression analyses were conducted for each outcome., Results: The prevalence of TDI in the sample was 41.5% and 16% of the children had enamel and dentin fractures. In the multivariate analysis, BMI and overjet were associated with the presence and severity of TDI (PR: 2.04 and 1.78, respectively) of TDI (PR: 2.27 and 2.24, respectively) (p < .001 for all associations)., Conclusion: Overweight/obesity was associated with both the presence and severity of TDI in early childhood., (© 2022 John Wiley & Sons A/S.

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., (© 2021 John Wiley & Sons A/S.

Background/aims: Occlusal features may increase the risk of dental trauma. The aim of the present study was to evaluate the association between occlusal characteristics and the occurrence of dental trauma in preschool children., Materials and Methods: A population-based case-control study was conducted with a representative sample of 200 children 3-5 years of age enrolled at private and public preschools in the city of Diamantina, Brazil. The case and control groups were matched for gender, age and type of preschool (public or private) at a ratio of 1:1 (100 cases and 100 controls). Independent variables of interest to the study (occlusal characteristics) and potential confounders (sociodemographic characteristics, sucking habits and lip coverage) were investigated. Intra-examiner and inter-examiner kappa values were higher than 0.80 for all oral conditions evaluated. The SPSS 22.0 program was used to analyse the data. Descriptive and univariate analyses as well as simple and multiple logistic regression analyses were performed., Results: The occlusal feature most strongly associated with trauma was anterior open bite (OR = 3.80; 95% CI: 1.42-10.16). Maxillary anterior crowding (OR = 2.14, 95% CI: 1.00-4.63) and overjet (OR = 1.12, 95% CI: 0.58-2.17) were associated with the occurrence of trauma independently of the confounding variables (sociodemographic characteristics, sucking habits and lip coverage), but these variables lost their significance when adjusted for other types of malocclusion. Anterior open bite remained strongly associated with dental trauma, regardless of confounding variables and other types of malocclusion., Conclusion: Anterior open bite was the main variable associated with dental trauma in the preschool children analysed independently of the confounding variables and the presence of other malocclusions., (© 2018 John Wiley & Sons A/S.

Purpose: The purpose of this study was to evaluate associations between traumatic dental injury (TDI) and maternal stress and demographic, behavioral, and clinical characteristics of schoolchildren., Methods: A cross-sectional investigation was conducted involving 396 eight- to 11- year-old schoolchildren in the city of Diamantina, Minas Gerais, Brazil. Maternal stress and demographic and behavioral (breastfeeding and non-nutritive sucking habits) factors were evaluated using a questionnaire. Overjet and TDI were recorded by a dentist who underwent training and a calibration exercise. Hierarchically-adjusted Poisson regression models were employed to determine factors associated with TDI., Results: In the final regression model, the prevalence of TDI was 75 percent higher among schoolchildren who were breastfed for less than six months (prevalence ratio [PR]=1.75; 95% confidence interval [CI]=1.16 to 2.66), 72 percent higher among those who engaged in finger-/thumb-sucking after three years of age (PR=1.72; 95% CI=1.16 to 2.56) and 91 percent among those with overjet greater than three mm (PR=1.91; 95% CI=1.29 to 2.84)., Conclusions: Breastfeeding duration, finger-/thumb-sucking and increased overjet were associated with TDI. These factors were aggravated by maternal stress, but it lost its significance in the multivariate analysis.

Background: The determination of risk factors for traumatic dental injury (TDI) is important to the implementation of preventive measures., Aim: The aim of this study was to evaluate the association between signs of attention deficit/hyperactivity disorder (ADHD) and TDI., Material and Methods: A case-control (1 : 1) study involved a population-based sample of 230 schoolchildren aged seven to 12 years. The case and control groups were composed of children with (n = 115) and without (n = 115) TDI, respectively. The groups were matched for age and sex. The outcome variable (TDI) was detected using the O'Brien criteria. The main independent variable (signs of ADHD) was evaluated using the Swanson, Nolan and Pelham scale (version IV) administered to parents and teachers. Socio-demographic characteristics and accentuated overjet were analyzed as confounding factors. Statistical analysis involved the McNemar's test as well as the bivariate and multivariate conditional logistic regression., Results: The multivariate regression demonstrated that schoolchildren with the signs of hyperactivity (parental reports) had a 2.33-fold greater chance of exhibiting TDI (95% CI: 1.10-4.94) than those without this condition, as well as those with accentuated overjet (OR = 3.13, 95% CI: 1.70-5.77)., Conclusion: Schoolchildren whose parents reported signs suggestive of hyperactivity had a greater chance of exhibiting TDI than those without such signs., (© 2016 BSPD, IAPD and John Wiley & Sons A/S.

Objective: The aim of this systematic review and meta-analysis was to search for scientific evidence regarding the factors associated with traumatic dental injury (TDI) in the primary dentition., Methodology: An electronic search addressing factors associated with TDI was conducted in the PubMed, ISI, LILACS, Cochrane Library, and Embase databases. Data were extracted and analyzed regarding risk factors, statistical test, effect measures, and study design., Results: The online search strategy led to the initial retrieval of 2566 articles. After evaluating the titles and abstracts, 24 papers were selected for complete review and data collection. TDI was associated with males (OR: 1.24; 95%CI: 1.09-1.41), inadequate lip coverage (OR: 1.81; 95%CI: 1.50-2.17), overbite (OR: 1.438; 95%CI: 0.94-2.19), and age (1 vs 2 years - OR: 0.47; 95%CI: 0.38-0.58; 2 vs 3 years - OR: 0.78; 95%CI: 0.67-0.91; 3 vs 4 years - OR: 0.82; 95%CI: 0.71-0.95). Overjet and anterior open bite were associated with TDI in the majority of studies., Conclusions: Males, older children, and those with inadequate lip coverage, overbite, or overjet are more likely to have TDI in the primary dentition., (© 2016 John Wiley & Sons A/S.

Background: The aim of study was to determine the occurrence of tooth injuries and associated factors among patients treated at a hospital emergency ward., Methods: A cross-sectional study was conducted involving the analysis of 790 patient charts. The independent variables were gender, place of residence and type of accident. The dependent variable was tooth injury (fractures, concussion, luxation and avulsion). Statistical analysis involved the chi-square test, Poisson analysis and logistic regression. Explanatory variables with a p-value < 0.20 in the bivariate analysis were incorporated into the multivariate model., Results: A total of 681 (86.2 %) patients had tooth injury, among whom 159 (20.1 %) had tooth fractures. Tooth concussion was associated with residence in urban areas (PR = 1.635; 95 % CI: 1.199-2.230), the male gender (PR = 1.673; 95 % CI: 1.225-2.285), violence (PR = 1.940; 95 % CI: 1.263-2.982) and sports (PR = 1.863; 95 % CI: 1.287-2.696). The prevalence rate of tooth fracture was higher among individuals having suffered a motorcycle (PR = 1.597; 95 % CI: 1.295-1.968) or bicycle accident (PR = 1.484; 95 % CI: 1.245-1.769). Victims of bicycle accidents had a 42.6-fold greater chance of suffering luxation (95 % CI: 20.917-86.808) and a threefold greater chance of suffering avulsion (95 % CI: 1.620-5.848). Victims of motorcycle accidents had a 2.96-fold greater chance of suffering avulsion (95 % CI: 1.471-5.937)., Conclusions: In the study, concussion was the most frequent type of tooth injury. Motorcycle and bicycle accidents were associated with tooth fractures, luxation and avulsion, whereas sports and violence were associated with dental concussion. The findings on tooth injuries can contribute to public health policies regarding the prevention and health promotion measures.

Objective: The aim of this study was to perform a systematic review and search for scientific evidence on the association between socioeconomic indicators and traumatic dental injury (TDI) in the primary dentition., Methodology: The PubMed, ISI, LILACS, Cochrane Library, and Embase databases were searched for articles addressing possible associations between socioeconomic indicators and TDI in the primary teeth in journals dating from the inception of the databases through to December 2013. Two independent reviewers performed data extraction and analyzed the quality of the studies. Meta-analysis was undertaken. Pooled estimates were calculated with a 95% confidence interval (CI) and odds ratios (OR)., Results: Sixteen articles were included in the systematic review. Children from families with household income less than two times average salary (U$ 592) (OR: 0.77; 95% CI: 0.66-0.90) or more than three times the average salary (U$ 888) (OR: 0.76; 95% CI: 0.65-0.89) had a significantly lower chance of having TDI in the primary dentition. TDI was not associated with socioeconomic status (high vs low - OR: 0.77; 95% CI: 0.43-1.36; high vs medium - OR: 1.03; 95% CI: 0.72-1.48; medium vs low - OR: 0.70; 95% CI: 0.42-1.19), house ownership (owned vs rented - OR: 1.28; 95% CI: 0.98-1.66), mother's schooling (OR: 0.89; 95% CI: 0.74-1.08), or father's schooling (OR: 1.01; 95% CI: 0.62-2.74)., Conclusion: The scientific evidence demonstrates that socioeconomic indicators are not associated with TDI in the primary dentition. The evidence of an association between a low income and TDI is weak. In general, studies had low risk of bias. Further prospective cohort studies are needed to confirm this association., (© 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

The aim of the present study was to determine the prevalence of traumatic dental injury (TDI) in the primary dentition and investigate associations with clinical and socioeconomic indicators. A population-based, cross-sectional study was carried out with a randomly selected sample of 301 children aged one to five years. Data were collected through clinical oral examinations and interviews with parents/guardians during immunization campaigns. Statistical analysis involved Pearson's Chi-squared test and Poisson regression with robust variance. The prevalence of TDI was 33.9%. TDI was more prevalent in children with overjet > 3 mm (p < 0.001) and those with inadequate lip coverage (p < 0 .001). A statistically significant association was also found between TDI and household income (p = 0.024). According to the adjusted Poisson regression model, greater prevalence rates of TDI were found for children from families with a monthly income ≥ twice the Brazilian minimum monthly wage (PR: 1.52; 95%CI: 1.10-2.12), those with accentuated overjet (PR: 1.53; 95%CI: 1.05-2.22) and those with inadequate lip coverage (PR: 2.00; 95%CI: 1.41-2.84). The prevalence of TDI was high in the present study and was associated with a higher family income, accentuated overjet and inadequate lip coverage.

Background/aim: Dental trauma has been associated with predisposing factors such as gender and age, and biological characteristics such as overjet and socio-economic factors. However, research literature associating the use of illicit drugs with dental trauma is scarce. The aim of this survey is to investigate the prevalence of dental trauma and the association of the same with the use of illicit drugs among adolescents., Material and Methods: A transversal analysis was conducted using a representative sample of 701 students between the ages of 14 and 19. Data were gathered by means of clinical examinations and self-administered questionnaires. The ABA-ABIPEME tool was adopted for the assessment of socio-economic conditions and ASSIST (Screening Test for Involvement with Alcohol, Cigarettes, and Other Substances) as a standard for the consumption of illicit drugs., Results: The prevalence of dental trauma was 26.6% (183/687) and that of illicit drug use 7% (48/684). Dental trauma was more prevalent among older adolescents (P = 0.010) with overjet greater than 3 mm (P = 0.005) in males (P = 0.001) who had used marijuana and/or cocaine in their lifetime (P = 0.005). The Poisson regression results revealed that illicit drug use was still associated with dental trauma independent of other variables [PR = 1.54 (95% CI: 1.06-2.24) P = 0.022]., Conclusions: The prevalence of dental trauma was high and associated with the use of illicit drugs., (© 2013 John Wiley & Sons A/S.

Background/aim: Facial trauma is among the most common types of injury. The aim of the present study was to assess the prevalence and pattern of oral-maxillofacial trauma stemming from interpersonal physical violence (IPV) and determine whether IPV is factor associated with oral-maxillofacial trauma., Materials and Methods: A retrospective analysis was conducted of 790 complete patient charts for data on the type of IPV for the gender, area of residence (urban or rural), age and type of trauma. Statistical analysis involved the chi-squared test (P < 0.05), univariate/multivariate Poisson, and logistic regression (P < 0.20). Type of oral-maxillofacial trauma was the dependent variable. Socio-demographic status and type of IPV were the independent variables., Results: One hundred forty (17.7%) individuals had oral-maxillofacial injuries stemming from IPV [80 (10.1%) due to urban violence (UV) and 42 (5.3%) due to domestic violence (DV)]. DV was more prevalent among females (69%), and UV was more prevalent among males (67.5%). The most common types of trauma were facial contusion and laceration, dental concussion, and mandibular fracture. Age and UV were explanatory factors for mandibular fracture. Females from rural areas and who suffered DV were more likely to exhibit facial contusion and dental concussion., Conclusions: Interpersonal physical violence was identified as a factor associated with oral-maxillofacial trauma, specifically mandibular fracture, facial contusion, and dental concussion., (© 2013 John Wiley & Sons A/S.

Background/aim: The joint evaluation of oral health-related quality of life and traumatic dental injury (TDI) is an important tool for setting priorities in public oral health programs. The purpose of the present study was to compare the impact of treated TDI, untreated TDI, and absence of TDI on the quality of life of schoolchildren aged 11-14 years., Material and Methods: A cross-sectional study was carried out with 668 schoolchildren from the city of Diamantina, Brazil. The clinical examination involved the determination of the presence and type of TDI based on the criteria proposed by O'Brien. Malocclusion was evaluated using the criteria of the Dental Aesthetic Index, and dental caries was diagnosed using the DMFT/dmft index. The impact of TDI on quality of life was assessed using the Child Oral Impact on Daily Performances (Child-OIDP). The outcome was the absence (Child-OIDP = 0) or presence (Child-OIDP ≥ 1) of impact on quality of life., Results: The prevalence of TDI was 34.3%. Schoolchildren with untreated TDI experienced a greater impact on eating (P = 0.016) and smiling (P < 0.001) in comparison with those without TDI. No significant differences were found in the Child-OIDP score between schoolchildren with treated TDI and those without trauma. The unadjusted and adjusted results of the Poisson regression analysis of the Child-OIDP demonstrated that schoolchildren with untreated TDI were more likely to experience an impact on 'eating and enjoying food', 'smiling and showing teeth', and 'overall score'., Conclusions: Untreated TDI was associated with a negative impact on the quality of life of schoolchildren, whereas treated TDI and absence of TDI were not associated with impact on quality of life., (© 2013 John Wiley & Sons A/S.

Aim: To investigate the association between dental trauma and alcohol use among adolescents between 14 and 19 years of age., Materials and Methods: A cross-sectional study was carried out involving a clinical exam performed by a calibrated researcher (intra-examiner Kappa = 0.93) and a self-administered questionnaire. The sample was representative of schoolchildren from the city of Diamantina (Brazil) and was made up of 738 adolescents. The type of school (public or private) was used as a socioeconomic indicator. Information on alcohol use (high risk and hazardous use) was acquired through the administration of the Alcohol Use Disorders Identification Test, which has been validated for use in Brazil., Results: The prevalence of dental trauma was 26.6%, and the prevalence of dangerous alcohol use was 44.3%. Dental trauma was significantly associated with a high risk of problems related to alcohol intake (P = 0.031), hazardous alcohol use (P = 0.009) and binge drinking (P = 0.036). The results of the Poisson logistic regression revealed that hazardous alcohol use [PR = 1.30 (95% CI: 1.01-1.66) P = 0.042] remained associated with dental trauma independently from age, gender, overjet, and type of school., Conclusions: The high prevalence of dental trauma found among adolescents in the city of Diamantina (Brazil) was greater among those at high risk for problems related to alcohol intake and was significantly associated with hazardous alcohol use., (© 2012 John Wiley & Sons A/S.)

Objectives: The aim of the present study was to assess parents' recognition of dental trauma in their children., Methods: A cross-sectional study was conducted in Belo Horizonte, Brazil, with 519 randomly selected children between 1 and 3 years of age. The parents answered questions on the occurrence of previous dental trauma, caregiver's schooling and the impact of dental trauma on activities and quality of life of the children. The children were also clinically examined for presence of dental trauma. Descriptive analysis, the chi-squared test, Mann-Whitney test and Poisson regression analysis were performed. The calculation of effect size was used to test the clinical significance of the findings., Results: A total of 41.2% (n = 214) of the children had at least one tooth with dental trauma. Among the parents of the children with dental trauma, 42.5% (n = 91) had not recognized the trauma. Mean caregiver's schooling was 8.9 ± 3.3 years of study. The schooling of caregivers who were unaware of the dental trauma was lower (mean: 5.3 ± 2.5 years of study) than that of those who were aware of the trauma (10.4 ± 2.1 years of study; P < 0.001). The recognition of dental trauma was more prevalent among parents of children over 24 months of age (PR: 3.5; 95% CI: 2.2-5.6), those whose children experienced an impact of oral health status on quality of life (PR: 1.2; 95% CI: 1.1-1.4) and those with a higher level of schooling (PR: 1.2; 95% CI: 1.1-1.2)., Conclusion: A large portion of parents do not recognize the occurrence of dental trauma in their toddlers. The age of the child, impact of oral health status on quality of life and caregiver's schooling were directly associated with parents' recognition of dental trauma in children aged 12 to 36 months., (© 2012 John Wiley & Sons A/S.)

The aim of the present study was to determine the prevalence of dental trauma and associated factors among a sample of patients with severe cerebral palsy. The sample was made up of 120 individuals equally divided into two groups. The group with cerebral palsy was made up of 60 patients diagnosed with the spastic form of the disease. The control group was made up of 60 individuals with no mental impairment. Questionnaires were used to collect information on individual, socioeconomic and behavioral characteristics. Dental trauma was assessed based on the clinical chart of each participant, on a questionnaire and on a clinical evaluation to determine past injuries. Mouth mirrors and millimeter periodontal probes (Community Periodontal Index probe) were used to measure overjet. Lip seal and breathing type were determined during the clinical exams and interviews. Statistical analysis involved the chi-square test (p < 0.05) and multivariate logistic regression (forward stepwise procedure). The prevalence of dental trauma was greater among individuals with cerebral palsy (18%) than in the control group (5%), with the difference achieving statistical significance (p = 0.023). Individuals with lip incompetence had a greater chance of exhibiting dental trauma (OR [CI 95%] = 3.81 [1.19-12.24]). The prevalence of dental trauma among individuals with cerebral palsy was high. A lack of lip seal was identified as a factor directly associated to this prevalence.

The aims of this study were to assess the epidemiology of traumatic dental injuries (TDI) to primary teeth in infants and toddlers between 1 and 3 years of age and investigate whether TDI was related to biological and social factors. A representative sample of infants and toddlers in the city of Belo Horizonte, Minas Gerais, Brazil (n = 519) was examined during a vaccination campaign. The evaluation of clinical signs of previous dental trauma was performed by nine previously calibrated examiners (intra-examiner Kappa = 0.95%; inter-examiner Kappa = 0.88%). Data were analysed through descriptive analysis, the chi-squared test (P < 0.050) and logistic regression. The prevalence of dental trauma was 41.6%. Among the 519 children examined, 193 (37.2%) had enamel fractures, 30 (5.7%) had enamel-dentin fractures and only three (0.6%) had enamel-dentin fractures involving the pulp. Dental care had been performed within the first 24 h in 4.1% of the sample and after 36 h in 0.8% of the sample. There was no statistically significant difference between genders. The most reported aetiologies were falls (28.8%) and collisions (6.8%). There were no statistically significant associations between the prevalence of dental trauma and non-nutritive sucking habits, dental caries or lip incompetence (P > 0.050). Children of mothers with low levels of schooling (0-6 years of study) had a greater prevalence of TDI (P = 0.001). The results of the logistic regression also demonstrated a significant association between dental injury and the Social Vulnerability Index (P = 0.045). Children from families with high social vulnerability (worse living conditions) had a 1.51 (95% confidence interval 1.0-2.2) greater chance of exhibiting TDI. These results can help guide the implementation of health promotion policies.

The objective of the study was to assess the prevalence of dental injuries and the influence of determining factors in preschool children from Belo Horizonte, Brazil. A cross-sectional survey was carried out through clinical examinations and the application of a questionnaire to the parents of 419 children aged 0 to 5 years attending preschool. The sample was stratified by region, type of institution and age. The eighteen preschools visited were chosen randomly. The prevalence of traumatic injury to primary teeth was 39.1%. Enamel fractures were the most common traumatic injury (49.7%). Boys were 1.62 times more likely to have dental injuries than girls. Children with inadequate lip coverage were 3.75 times more likely to have a traumatic dental injury than those with adequate lip coverage. Children attending state preschools had nearly two times greater chances of having dental trauma than children attending private preschools. It was concluded that the prevalence of dental injuries in preschool children is high in Belo Horizonte, Brazil and constitutes a public health problem.

We estimated the incidence of traumatic dental injuries (TDI) in a 2-year follow-up of adolescents with and without previous dental trauma and verified the hypothesis that individuals with previous trauma are more prone to recurrent TDI events. The present study was developed in three phases. First, a dental trauma cross-sectional study was carried out with 2260 schoolchildren aged 11-13 years in Biguaçu, southern Brazil. In the second phase, a case-control study was developed to identify risk factors associated with dental trauma. The third step was a 2-year longitudinal observational study with the participants of the second phase of the study. The exposed group of individuals with previous dental traumatism (208) and a non-exposed group (208) of participants who had no previous signs of dental trauma were followed up for 2 years. Descriptive, univariate, simple and conditional multiple logistic regression analyses were performed. The greatest incidence of dental trauma was identified among adolescents with previous dental trauma (11.9%-11.44/1000 incisors) when compared with those without previous dental trauma (2.7%-2.45/1000 incisors) (P < 0.001). In the study period, adolescents with previous dental trauma showed a 4.85 times greater odds ratio for presenting further dental trauma when compared with adolescents without previous dental trauma (P = 0,005) after adjusting for incisal overjet, lip coverage and mother's schooling. A notable difference was observed regarding the incidence of TDI between the case and control groups. Individuals with previous dental trauma had greater chances of developing develop further dental trauma in a 2-year follow-up.

Background/aim: Among the diseases related to oral health, traumatic dental injuries (TDI) can lead to pain, loss of function and aesthetic problems, with physical, emotional and social consequences for children and their families. The aim of this study was to investigate the relationship between enamel fracture and enamel-dentin fracture with oral health-related quality of life (OHRQoL).Material and Methods: This cross-sectional study had a representative sample of 1589 children between 8-10 years of age from public schools. The OHRQoL was obtained through the Child Perceptions Questionnaire (CPQ8-10 ), which is a questionnaire validated for Brazilian children. Clinical data were collected by 4 calibrated examiners (Kappa > 0.7) using the Decay, Missing, Filled Teeth (DMFT) Index, Dental Aesthetic Index (DAI) and TDI. A socio-economic questionnaire was sent to the caregivers to be answered at home. Descriptive statistics and Poisson regression with prevalence ratio (PR) and 95% confidence interval (CI) were used for statistical analysis.Results: The prevalence of TDI was 10.6%, and among these 10.3% who had an impact on the OHRQoL, it was due to enamel-dentin fracture. Children with enamel-dentin fracture had (PR 1.35; 95% CI 1.07-1.70) higher prevalence of impact on the OHRQoL. Children with enamel fracture had no impact on the OHRQoL (P = .254).Conclusion: Enamel fracture had no significant impact on children's quality of life, while enamel-dentin fracture did have an impact on quality of life.

Aim: To investigate the association between oral conditions and trouble sleeping among preschool children. Subject and methods: A population-based cross-sectional study was carried out with a representative sample of 837 children aged 3-5 years. Dental caries, traumatic dental injury (TDI) and malocclusion were determined through clinical examinations. The DMFT index and the classification proposed by Andreasen et al. (2007) were used to diagnose dental caries and TDI, respectively. Parents/caregivers answered a questionnaire about socioeconomic indicators, child's oral health, child's visits to the dentist and history of toothache. They were also questioned as to whether their children had trouble sleeping due to dental reasons (dependent variable). Descriptive analysis and hierarchically adjusted logistic regression models were used ( p < 0.05, 95 % CI). Results: Trouble sleeping was significantly more prevalent among children whose parents/caregivers perceived their child's oral health to be poor (PR = 2.81; 95 % CI:1.26-6.30), those who had been to the dentist (PR = 3.02; 95 % CI:1.53-6.00), those with a history of toothache (PR = 23.75; 95 % CI:8.00-70.60), those with high severity of caries (six or more cavitated lesions; PR = 3.13; 95 % CI:1.16-8.42) and those with malocclusion (PR = 2.31; 95 % CI:1.08-5.00). No association was found between trouble sleeping and TDI. Conclusion: Parents/caregivers' perception of poor oral health status in their children, history of visit to dentist, history of toothache as well as the severity of dental caries and malocclusion were associated with trouble sleeping in preschool children.

The aim of this study was to investigate the impact of treatment for Enamel-Dentin Fracture (EDF) on the daily activities of adolescents. This was a case-control study (1:4). The case group was composed of 40 adolescents from 11 to 17 years of age, presenting definitive restoration treatment for EDF for over 6 months. The control group was made up of 160 adolescents with no history of dental trauma and belonging to the circle of friends of the participants of the case group, matched by gender, age, and socioeconomic level. The outcome variable ‘impact’ was assessed through the Oral Impact on Daily Performances (OIDP). The independent variables were collected for being of interest to the study (dental trauma) or for acting as potential confounding factors (malocclusion, decay, and mother's education). Descriptive, univariate, simple and multiple logistic regression analyses were performed. Among the cases, the impact prevalence was 40.0%, whereas among the controls it was 16.9%. The more affected daily activities were showing the teeth (18.0%), eating (6.5%), speaking (2.0%), and cleaning the mouth (0.5%). The odds ratio of adolescents treated for EDF of presenting an impact on daily activities was 3.3 times (confidence interval 95%: 1.4–7.7) greater than among adolescents without dental trauma, controlling for mother's education, decay and the presence of malocclusion. Adolescents whose teeth have been esthetically treated for EDFs run a greater risk of presenting OIDP when compared to adolescents that have never suffered dental injuries. [ABSTRACT FROM AUTHOR]
