Do binge drinking adolescents have a greater number of traumatised teeth? A longitudinal study with 12-year-olds in Brazil.

BACKGROUND: Binge drinking has been linked to traumatic dental injury (TDI). Once drunk, adolescents are more prone to accidents, which may result in orofacial injury. AIM: This study evaluated the possible association of binge drinking with a number of traumatised teeth in a population of 12-year-old Brazilian adolescents in 2013 and 2015. DESIGN: This study was longitudinal, carried out with 588 adolescents at two moments, 2013 and 2015. TDI, overjet and lip protection were assessed by calibrated examiners. Binge drinking data were collected through the Alcohol Use Disorders Identification Test. Sociodemographic indicators were obtained through a questionnaire answered by the parents/guardians. The Poisson regression model with a random effects intercept was estimated. RESULTS: A higher prevalence of traumatised teeth was observed among adolescents who binge drink (IRR = 1.37; 95% CI: 1.05-1.80; p < .05). The prevalence was also significantly higher among adolescents in this age range with a ≥ 3-mm overjet and those with inadequate lip protection (IRR = 1.99; 95% CI: 1.44-2.76; p < .001 and IRR = 3.41; 95% CI: 2.57-4.53; p < .001, respectively). CONCLUSION: A greater number of traumatised teeth were found among adolescents who reported binge drinking and had severe overjet and inadequate lip coverage.

Is Binge Drinking Associated with Suicidal Behaviors among Brazilian Adolescents?

OBJECTIVE: To evaluate the association between suicidal behaviors and binge drinking among Brazilian adolescents. METHODS: A cross-sectional study was conducted with 2,476 students 14 to 19 years of age from 26 public high schools in the city of Olinda, Brazil. Data collection occurred between March and June 2018 through the self-administered Youth Risk Behavior Survey. Descriptive analysis and Poisson regression (p < 0.05, 95%CI) were performed. RESULTS: The prevalence of suicidal ideation, planning and attempt in the previous 12 months was 23.7%, 17.4% and 13.5%, respectively. Suicidal ideation was associated with binge drinking one to two days (PR:1.053, 95%CI:1.011-1.096) and ≥ three days in the previous 30 days (PR:1.069, 95%CI:1.016-1.125), sadness/hopelessness in the previous 12 months (PR:1.313, 95%CI:1.267-1.360), a report of family physical aggression in the previous 12 months (PR:1.111, 95%CI:1.068-1.155), the female sex (PR:1.082, 95%CI:1.049-1.115) and a non-nuclear family (PR:1.037, 95%CI:1.004-1.071). Suicidal planning was associated with sadness/hopelessness in the previous 12 months (PR:1.257, 95%CI:1.214-1.302), report of family physical aggression in the previous 12 months (PR:1.110, 95%CI:1.065-1.156) and the female sex (PR:1.072, 95%CI:1.041-1.104). Suicide attempt was associated with binge drinking ≥ three days in the previous 30 days (PR:1.062, 95%CI:1.008-1.119), sadness/hopelessness in the previous 12 months (PR:1.202, 95%CI:1.161-1.244), report of family physical aggression in the previous 12 months (PR:1.105, 95%CI:1.060-1.153) and the female sex (PR:1.064, 95%CI:1.034-1.095). The Catholic (PR:0.938, 95%CI:0.899-0.979; PR:0.925, 95%CI:0.888-0.9865; PR:0.937, 95%CI:0.899-0.977) and Evangelical (PR:0.956, 95%CI:0.922-0.992; PR:0.954, 95%CI:0.919-0.991) religions acted as a possible protective factor against suicidal behaviors. CONCLUSIONS: Suicidal ideation and attempt were associated with binge drinking.

LGB prevalence in schools is associated with unhealthy weight-control behaviors in lesbian, gay, and bisexual youth: a multilevel analysis.

BACKGROUND: Previous studies have found that a school climate of more heteronormativity is associated with adverse effects on the mental health of LGB students. Accordingly, our aim was to assess the association between lower LGB prevalence in schools and unhealthy weight-control behaviors among LGB youth. METHODS: A cross-sectional, multilevel study based in public high schools in the city of Olinda, Northeast Brazil. A multilevel logistic regression was performed, including 2500 adolescents enrolled in 27 schools. The contextual variable was the prevalence of LGB youth in each school (as a proxy for heteronormativity in schools), while the outcome was unhealthy weight-control behaviors (fasting, purging, and taking diet pills). We controlled for socioeconomic characteristics (age, sex, receiving a family allowance), obesity, and self-reported happiness. RESULTS: Lower LGB prevalence in schools was associated with higher odds of engaging in unhealthy weight-control behaviors (OR: 1.5, 95%CI: 1.0, 2.2) among all youth, regardless of sexual orientation. No cross-level interactions between school context and individual characteristics were statistically significant. CONCLUSION: Lower LGB prevalence in schools was associated with a higher risk of unhealthy weight-control behaviors in youth regardless of sexual orientation, which may reflect either the contextual influence of school climate, or may be due to residual confounding.

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.

Amelogenesis imperfecta: use of cyanoacrylate as a desensitizing agent and its impact on oral health-related quality of life.

Amelogenesis imperfecta (AI) is a rare hereditary condition characterized by abnormal enamel formation and increased tooth sensitivity. There are no defined therapeutic recommendations for tooth sensitivity in patients with AI. The aim of the present case report of a 5-year-old girl with AI is to describe the use of cyanoacrylate as a desensitizing agent on the patient's permanent molars and report the impact of this treatment on her oral health-related quality of life (OHRQoL). After 4 sodium fluoride varnish applications were unsuccessful in relieving sensitivity affecting the molars, cyanoacrylate was applied 5 times (at intervals of 7, 15, 30, and 180 days after the first application). Pain scores were recorded on a visual analog scale before and after each intervention, and the OHRQoL was measured using a questionnaire (Early Childhood Oral Health Impact Scale [ECOHIS]) administered prior to the first cyanoacrylate application and on the last day of the protocol. In this patient, cyanoacrylate seemed to be effective at decreasing tooth sensitivity in immature permanent molars affected by AI, as demonstrated by reductions in the frequency of complaints of dental pain, difficulty in drinking cold beverages, and difficulty in eating some foods.

Recognition of child physical abuse by a group of Brazilian primary care health professionals.

BACKGROUND: Child maltreatment is a complex social and public health problem. AIM: To evaluate the frequency of the recognition by Brazilian health professionals in primary care of child physical abuse (CPA) and associated factors. DESIGN: A representative cross-sectional study was conducted with dentists, nurses, family physicians, and pediatricians who participated in the network of the Family Health Strategy in the city of Belo Horizonte, Brazil. Data collection involved in the administration of a questionnaire validated for use in Brazil. Data were collected from 181 dentists, 235 nurses, 203 family physicians, and 96 pediatricians. RESULTS: Among the 715 health professionals, 499 (69.8%) had some type of postgraduate degree and 414 (57.9%) recognized suspected or proved cases of CPA. The recognition was associated with occupation, as pediatricians recognized 14.11-fold [OR = 14.11 (95% CI: 3.73 to 53.43)] more cases of CPA compared with dentists. The recognition was also associated with a longer period of time working in the city [OR = 2.79 (95% CI: 1.24 to 6.29)]. CONCLUSION: The recognition of cases was positively associated with the longer working time in the municipal network and with pediatricians. The dentist was the category that was least associated with the recognition of CPA.

Traumatic dental injuries in Brazilian children and oral health-related quality of life.

BACKGROUND/AIMS: Population-based studies that investigate the impact of TDI on oral health-related quality of life (OHRQoL) among school children and its association with socioeconomic factors are scarce and offer conflicting results. The aim of this study was to evaluate the impact of TDI on OHRQoL among school children and its association with socioeconomic status. MATERIALS AND METHODS: A cross-sectional study was conducted with 588 12-year-old children enrolled in public and private schools in the urban areas in the city of Diamantina (southeastern Brazil). Clinical examinations were performed for the diagnosis of traumatic dental injury based on Andreasen's classification. The Child Perceptions Questionnaire (CPQ11-14 ), which has been validated for the population in Brazil, was employed to evaluate oral health-related quality of life. Socioeconomic status and overjet were also analyzed. Statistical analysis involved the chi-square test and logistic regression. RESULTS: A total of 29.4% of the students exhibited some type of trauma to at least one tooth. A negative impact on oral health-related quality of life was found in 53.1% of the sample. Traumatic dental injury was associated with a high impact on oral health-related quality of life [OR = 1.61 (95% CI: 1.08-2.39)] and overjet >3 mm [OR = 5.42 (95% CI: 3.66-8.02)]. However, no statistically significant associations were found between TDI and socioeconomic status. CONCLUSIONS: Prevalence of traumatic dental injury was high among the children who participated in the study, and it was associated with a high impact on oral health-related quality of life as well as overjet >3 mm.

The prevalence of dental trauma and its association with illicit drug use among adolescents.

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.

Health Professionals: Identifying and Reporting Child Physical Abuse-a Scoping Review.

Health professionals play a significant role in identifying and reporting child physical abuse (CPA). However, several studies have pointed out non-reporting behavior among these professionals, evidencing difficulties identifying and reporting suspected cases. This review aimed to explore the frequency and possible barriers in identifying and reporting CPA by health professionals worldwide and to identify associated factors. This scoping review was conducted in the Pubmed, Web Of Science, Scopus, and SciELO databases between July 2019 and December 2020. Analytical and qualitative observational epidemiological studies were selected and published in English, Portuguese, and Spanish, with data on the identification and/or reporting of CPA by health professionals. Twenty studies fulfilled the criteria of this review. The studies were conducted with dentists, nurses, pediatricians, and general practitioners. The frequency of identification of CPA ranged from 50% to 89%, while the frequency of reporting ranged from 8% to 47%. This review revealed that health professionals had a low frequency of reporting of CPA, especially for dentists. In addition, several associated factors and barriers in the identification and reporting of CPA were identified in the studies. These were discussed in five main themes: training and continuing education in CPA, impact on professional practice, experiences and perceptions about child protection services, the threshold for suspicion of the professional, and the professional category.

Parents' recognition of dental trauma in their children.

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.

Does religiosity impact binge drinking among early adolescents? A cross-sectional study in a city in Southeastern Brazil.

This study evaluated the association between religiosity and binge drinking in early adolescence. A cross-sectional study was conducted with adolescents aged 10-13 from Belo Horizonte, Brazil. Stratified random sampling was performed considering the administrative district and school year. Adolescents filled an AUDIT-C form, containing questions about religiosity and binge drinking by parents and their best friends. Adolescents' caregivers answered a form regarding socioeconomic issues. Descriptive analysis, univariate, and multivariate logistic regression were performed. A total of 650 adolescents participated in the study. The frequency of binge drinking was 13.7%. In the adjusted model, religiosity was not associated with binge drinking. The covariates associated were the age of 12-13 years (OR: 1.94; CI95%: 1.06-3.56; p=0.030), maternal binge drinking (OR: 3.12; CI95%: 1.76-5.52; p<0.001) best friend binge drinking (OR: 6.01; CI95%: 3.40-10.62; p<0.001) and nonnuclear family (OR: 1.80; CI95%: 1.01-3.23; p=0.045). The findings revealed that, for binge drinking, the main factors that influenced this decision were the best friend and maternal binge drinking and family structure, although the adolescents claimed to be religious.

Prevalence of oral health-related shame and associated factors among Brazilian schoolchildren.

The aim of the present study was to investigate the prevalence of oral health-related shame and the associated factors among 8-to-10-year-old Brazilian schoolchildren. A cross-sectional study was conducted with 388 children randomly selected from public and private schools of Diamantina, southeastern Brazil. In order to identify the feeling of shame, self-reports were collected through a single question, "In the last month, did you feel ashamed because of your teeth or mouth? Two calibrated examiners performed the clinical examination for dental caries (DMFT/dmft index), traumatic dental injuries (O' Brien), and malocclusion (Dental Aesthetic Index). Sociodemographic indicators were obtained through a questionnaire answered by the children's caregivers. Descriptive analysis, chi-square test, and hierarchical Poisson regression models were performed (95%CI; p < 0.05). The prevalence of shame was 38.1% (n = 148). The adjusted regression analysis demonstrated a significant association between shame and untreated dental caries (PR: 1.34; 95%CI: 1.04-1.74; p = 0.02), age of 10 years (PR: 1.36; 95%CI: 1.05-1.76; p = 0.01), and with parents with less than eight years of schooling (PR: 1.30; 95%CI: 1.00-1.68; p = 0.04). Older children with untreated dental caries and whose parents had lower education level presented a higher prevalence of oral health-related shame.

Determinant factors for immediate care seeking after traumatic dental injury among Brazilian children.

The present study aimed to evaluate the frequency of immediate care seeking after traumatic dental injury (TDI) in primary dentition and its association with the children's characteristics, socioeconomic status, and TDI characteristics. This was a cross-sectional study with dental records of children aged 9 months to 6 years who attended a reference center in TDI in primary dentition between 2007 and 2018. Immediate care seeking after TDI, child's characteristics, sociodemographic conditions and TDI characteristics were collected. Descriptive statistics and Poisson regression analysis with robust variance were performed (p < 0.05; 95%CI). Among the 493 dental records, 61.1% (n = 301) were of males and 50.5% (n = 249) were from children aged 2 years or less. More than one third of the sample (36.9%; n = 182) sought immediate care after TDI. Among the types of TDI, the prevalence of soft tissue injuries was 59.0% (n = 291), while 51.7% (n = 255) were hard tissue injuries and 54.0% (n = 266) were supporting tissue injuries. Immediate care seeking after TDI was higher in children who needed suture (PR: 1.39; 95%CI: 1.01-1.92. p = 0.039), had luxation (lateral, intrusion, or extrusion) (PR: 2.36; 95%CI: 1.36-4.08. p = 0.002) or avulsion (PR: 2.18; 95%CI: 1.28-3.70. p = 0.004). The need for suture, luxation (lateral, intrusion and extrusion), and avulsion were determinant factors for the immediate care seeking after TDI, regardless of the child's characteristics and socioeconomic status.

Prevalence of recognition and reporting of child physical abuse by dental surgeons and associated factors.

Studies evaluating the factors associated with under reporting and with the recognition and reporting of child physical abuse are scarce and highly necessary. This study aimed to assess the prevalence of recognition and reporting of child physical abuse (CPA) by Brazilian dentistsin primary care and associated factors. A cross-sectional study was carried out with a representative sample of dentistsfrom the Family Health Strategy in Belo Horizonte. A self-administered questionnaire validated to Brazilian Portuguesewas used for data collection. Statistical analysis included univariate and multiple analyses through Poisson regression. A total of 181dentists participated in the study. Among them, 73 (40.3%) had already recognized some cases of CPA, but only 11 (6.1%) ended up reporting. Dentists with six to 19 years of experience as a municipal worker presented 2.38 times [PR = 2.38 (95%CI: 1.29-4.41)] more probability to recognize cases of CPA than the ones with less than six years. Having a graduate degree with a major in childcare [PR = 4.50 (95%CI: 1.08-18.68)] was associated with a larger number of reports. The employment duration as municipal worker was positively associated with the recognition of CPA cases and the prevalence of reporting was low.

Reporting of child physical abuse by a group of Brazilian primary care health professionals and associated factors.

BACKGROUND: Evidences points to the importance of health professionals to recognize child abuse, but also to a high frequency of underreporting, even in countries where reporting is mandatory, like Brazil. OBJECTIVE: To evaluate the frequency of non-reporting behavior of child physical abuse (CPA) among Brazilian primary care health professionals who recognized some cases in their careers and associated factors with reporting. METHODS: Cross-sectional study conducted with a representative sample of dentists, nurses, family physicians, and pediatricians from the Family Health Strategy network in the city of Belo Horizonte, Brazil. A validated self-administered questionnaire for use in Brazil was applied in-person to professionals in 2014 and 2015. Pearson's chi-squared test (p < 0.05) and a binary logistic regression model was used. RESULTS: A total of 715 professionals participated (response rate: 98.89%), 414 (57.3%) recognized cases, of which 171 (41.3%) reported. Reporting was associated with the type of profession, as pediatricians reported cases more than dentists [OR = 6.05 (95% CI: 1.24-29.50)], with the willingness to become involved [OR = 2.01 (95% CI: 1.02-3.97)] and knowledge regarding where to report cases [OR = 2.68 (95% CI: 1.25-5.74)]. Confidentiality was the barrier associated with a lower probability of reporting CPA cases [OR = 0.22 (95% CI: 0.08-0.66)]. CONCLUSIONS: There is a high frequency of non-reporting behavior. Pediatricians reported more CPA cases, followed by family doctors and nurses. Dentists were those who reported fewer cases. Reporting was also associated with a willingness to be involved in detecting/reporting abuse and knowing where to report CPA.

School academic climate and oral health (tooth loss) in adolescents.

BACKGROUND: Preventing tooth loss depends on oral health maintenance behaviors. This study hypothesized that adolescents with educational aspirations have greater motivation to invest in the future, including maintenance of oral health status. AIM: To analyze the association between a school academic climate of educational aspirations and tooth loss (first permanent molars) among adolescents. METHODS: A cross-sectional study was designed to include 2,500 adolescents (aged 14-19 years) enrolled in public high schools of Olinda located in Northeast Brazil. Multilevel Poisson regression random intercept models were conducted with tooth loss (first permanent molars) as the outcome. The primary cohort of interest was school academic climate, as measured by the proportion of students taking the national high school exams. RESULTS: Tooth loss of the first permanent molars (assessed by clinical exam) was more prevalent in adolescents from more disadvantaged backgrounds (receiving family allowance, low maternal education). However, after controlling for a wide range of individual characteristics, adolescents enrolled in schools with lower academic climate had a higher prevalence of tooth loss (PR 1.42, 95%CI: 1.09,1.85). CONCLUSION: The school academic climate is associated with tooth loss, suggesting that educational aspirations are linked to adolescent oral health maintenance behaviors.

Unusual exophytic gingival lesion in a newborn treated with diode laser.

Gingival lesions rarely occur in newborns. However, when present, they commonly worry the parents and impair the infant's feeding, thus affecting growth. Such lesions are usually nonneoplastic in nature, although malignancies may develop; therefore, specimens must be submitted for histopathologic examination. A 2-month-old girl presented with a 10-mm nodule on the anterior lower alveolar ridge in association with natal tooth extraction and neonatal tooth eruption. The lesion was excised with high-power laser under local anesthesia, and a histopathologic diagnosis of a peripheral ossifying fibroma was made. In addition to peripheral ossifying fibromas being rare in newborns, the use of high-power lasers for surgical procedures in newborns have been proven to be safe, comfortable, and efficient.

Association between cigarette use and adolescents' behavior.

OBJECTIVE: To determine the prevalence of cigarette use among adolescents and to identify associated health risk behaviors. METHODS: This is a cross-sectional study with a representative sample, composed of 1059 adolescents between 13 and 19 years old, enrolled in primary and secondary public schools of Olinda, Pernambuco, in 2014. Information was obtained through self-administered questionnaires (validated version of YRBS 2007). Cigarette experimentation was defined as smoking at least once in life. Adolescents who smoked at least one day within 30 days prior to the survey were considered current smokers. Most students were female and 16 years old or older. RESULTS: Almost 30% used it in life and about 10% smoked within the 30 days before the survey. Suicidal ideation (PR = 1.51, 95%CI 1.25-1.82), alcohol use (PR = 1.41, 95%CI 1.03-1.92), marijuana (PR = 1.64, 95%CI 1.37-1.96), excessive alcohol consumption (PR = 1.57, 95%CI 1.15-2.16) and sexual experience (PR = 1.78, 95%CI 1.43-2.21) have increased the risk of using cigarettes. Feelings of sadness (PR = 1.70, 95%CI 1.22-2.36), alcohol use (PR=2.40, 95%CI 1.12-5.12), excessive alcohol consumption (PR = 2.5, 95% CI 1.24-5.38), marijuana (PR = 2.31, 95%CI.57-3.39) and cocaine (PR = 1.99, 95%CI.32-3.01) increased the risk of cigarette use within the 30 days before the survey. CONCLUSIONS: Cigarette use among adolescents from Olinda was high, being considered higher than the national prevalence. Possible factors associated with cigarette use were drug use (alcohol, marijuana, and cocaine) and behaviors related to sexual experience, feelings of sadness and suicidal ideation.

Prevalence and factors associated to dental trauma in infants 1-3 years of age.

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.

Correlation between socioeconomic indicators and traumatic dental injuries: a qualitative critical literature review.

BACKGROUND/AIM: Traumatic dental injuries are widespread and have become a serious dental public health problem in childhood. Despite its importance, very few studies have correlated the prevalence of permanent tooth injury and socioeconomic indicators. The aim of the present study was to evaluate just such a correlation. MATERIALS AND METHODS: Electronic searches were performed in the following bibliographical databases: Brazilian Bibliography of Dentistry, Scientific Electronic Library Online, Latin American and Caribbean Health Sciences, The Cochrane Library, ISI Web of Knowledge, International Database for Medical Literature and PubMed Central. Reference lists from articles that fulfilled the inclusion criteria in this review were searched for additional relevant articles. The Brazilian Coordination of Higher Education Personnel Improvement Theses Databank was also included. Selection and analysis of the articles were performed independently by two authors of the present literature review. RESULTS: A total of 21 of 98 articles were eligible for inclusion in the review. However, only nine articles performed all the methodology criteria analyzed. Seven of the surveys were carried out in Brazil and two in Thailand. The age of children was 9-14 years. Statistically significant associations between permanent tooth injuries and high economic status were found in four studies. CONCLUSION: There were few studies correlating traumatic injuries in permanent teeth and socioeconomic indicators and the majority found no such association. It is suggested that the association between traumatic dental injuries and socioeconomic factors may be related to the indicators used, considering differences in their individual components. Furthermore, the heterogeneity of the methodologies hinders the comparison of the studies.
