Rare dental developmental disturbance in primary and permanent teeth following trauma prior to tooth eruption: Case report.

Traumatic dental injuries are highly prevalent among preschool children. When occurring at a very young age (prior to the eruption of the primary teeth), such trauma can disturb the normal development of the permanent dentition and, more rarely, affect the primary dentition. This report describes a case of a patient who suffered dentoalveolar trauma at six months of age that caused rare developmental problems in the primary dentition, such as impaction, dilacerations, hypoplasia, and odontoma. Imaging revealed that alterations also occurred in the permanent dentition. This report demonstrates that dentoalveolar trauma prior to complete development of the dentition and even before the eruption of the primary teeth can lead to highly uncommon abnormalities in the primary dentition. Moreover, there may be repercussions in the permanent dentition when the germs of these teeth are injured by the intraosseous displacement of primary teeth.

Prevalence of traumatic dental injuries and its association with binge drinking among 12-year-olds: a population-based study.

OBJECTIVE: To determine the prevalence of traumatic dental injuries and its association with binge drinking among 12-year-old schoolchildren. METHODS: A cross-sectional study was carried out involving 588 students from a medium-sized city in Brazil. Data were collected through a clinical examination and self-administered questionnaires. Andreasen's classification was used for the determination of traumatic dental injuries. The consumption of alcoholic beverages and binge drinking were evaluated using the Alcohol Use Disorders Identification Test--Consumption. Socio-economic status, overjet, and inadequate lip seal were also analysed. Associations were tested using the multivariate logistic regression analysis. RESULTS: The prevalence rates of traumatic dental injuries, alcohol consumption in one's lifetime, and binge drinking were 29.9%, 45.6%, and 23.1%, respectively. The prevalence of traumatic dental injuries was significantly higher among those who engaged in binge drinking (PR = 1.410; 95% CI: 1.133-1.754) and even higher among those with inadequate lip protection and accentuated overjet (PR = 3.288; 95% CI: 2.391-4.522 and PR = 1.838; 95% CI: 1.470-2.298, respectively). CONCLUSIONS: A higher prevalence rate of traumatic dental injuries was found among 12-year-olds who engaged in binge drinking. The high rate of alcohol intake among adolescents is worrisome considering the vulnerability of this population due to the intense transformations that occur in the transition from childhood to adulthood.

Association between dental trauma and alcohol use among adolescents.

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.

Association between binge drinking, type of friends and gender: a cross-sectional study among Brazilian adolescents.

BACKGROUND: Hazardous drinking among adolescents is a major public health concern. The purpose of this study was to examine the prevalence of binge drinking/alcohol consumption and its association with different types of friendship networks, gender and socioeconomic status among students in Belo Horizonte, Minas Gerais, Brazil. METHODS: We conducted a cross-sectional study on a representative random sample of 891 adolescents (41% male, aged 15-19 years) from public and private schools in 2009-2010. Information on friendship networks and binge drinking was collected using two validated self-administered questionnaires: the Integrated Questionnaire for the Measurement of Social Capital and the first 3 items in the Alcohol Use Disorders Identification Test (AUDIT C). We used the area-based Social Vulnerability Index (SVI), mother and father's educational background, and the type of school to assess socioeconomic status. The chi-squared test was used to examine the associations between sample characteristics or the type of friends and binge drinking (p-values <0.05 were considered statistically significant). Ordinal logistic regression was used to estimate the association between binge drinking and the independent variables. RESULTS: A total of 321 (36%) adolescents reported binge drinking (5 or more drinks in one occasion), and among them, 233 (26.2%) adolescents reported binge drinking less than monthly to monthly, and 88 (9.9%) weekly to daily. Binge drinking was associated with being male (OR = 1.52, 95% CI 1.01-2.28) and with living in a low vulnerability area (having the best housing conditions, schooling, income, jobs, legal assistance and health) (OR = 1.66, 95% CI 1.05-2.62). Students who reported that their closest friends were from school (as opposed to friends from church) had an increased risk of binge drinking (OR = 3.55, 95% CI 1.91-5.87). In analyses stratified by gender, the association was significant only among the female students. CONCLUSIONS: The prevalence of binge drinking was high in this sample of Brazilian adolescents, and gender, low social vulnerability and friendship network were associated with binge drinking.

Prevalence and association of dental injuries with socioeconomic conditions and alcohol/drug use in adolescents between 15 and 19 years of age.

BACKGROUND: The aim of the present study was to investigate the prevalence of dental trauma, etiological factors, predisposing factors, and associations with socioeconomic status and the risk of alcohol and illicit drug use among adolescents in the city of Belo Horizonte, Brazil. METHODS: A cross-sectional study was carried out that included clinical examinations and self-administered questionnaires. The sample population was composed of 891 adolescents from public and private schools. The Social Vulnerability Index (SVI) was used for socioeconomic classification. Information on alcohol and illicit drug use was obtained using two questionnaires: the Alcohol Use Disorders Identification Test (AUDIT) and the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). RESULTS: The prevalence of traumatic dental injury (TDI) was 24.7%. Falls (17.7%) was the most frequently cited etiological factor in dental injury. Among the participants with TDI, 32.8% were students in the private school system (P = 0.006). A total of 56.8% of individuals with accentuated overjet had some type of TDI (P = 0.000). There was a high prevalence of adolescents who consumed alcoholic beverages (50.3%) and used illicit substances (15.2%). However, no statistically significant associations were found between these variables and the presence of TDI. The results of the analysis demonstrate that individuals in a private school system [prevalence ratio (PR) = 1.11; 95% confidence interval (CI): 1.03-1.20] and those with accentuated overjet (>3 mm) (PR = 1.17; 95% CI: 1.10-1.25) had a 1.11- and 1.17-fold greater chance of belonging to the group of individuals diagnosed with some type of TDI. CONCLUSIONS: The prevalence of dental trauma in the study population was high. The same was true regarding alcohol and illicit drug use among the adolescents examined, although no statistically significant associations were found between these variables and a history of TDI. Private school system and accentuated overjet were significantly associated with dental trauma.

Cross-cultural adaptation of the Child Perceptions Questionnaire 11-14 (CPQ11-14) for the Brazilian Portuguese language.

BACKGROUND: Oral-Health-Related Quality of Life (OHRQoL) instruments are being used with increasing frequency in oral health surveys. However, these instruments are not available in all countries or all languages. The availability of cross-culturally valid, multi-lingual versions of instruments is important for epidemiological research. The Child Perceptions Questionnaire 11-14 (CPQ11-14) is an OHRQoL instrument that assesses the impact of oral conditions on the quality of life of children and adolescents. The objective of the current study was to carry out the cross-cultural adaptation of CPQ11-14 for the Brazilian Portuguese language. METHODS: After translation and cross-cultural adaptation, the CPQ 11-14 was tested on 160 11-to-14-year-old children who were clinically and radiographically examined for the presence or absence of dental caries. The children were receiving dental care at the Pediatric Dental and Orthodontic clinics of the Federal University of Minas Gerais, Brazil. To test the quality of the translation, 17 children answered the questionnaire. The internal consistency of the instrument was assessed by Cronbach's Alpha Coefficient and the test-retest reliability by Intraclass Correlation Coefficient (ICC). RESULTS: The mean CPQ11-14 score were 24.5 [standard deviation (SD) 18.27] in the group with caries and 12.89 [SD 10.95] in the group without caries. Median scores were 20 and 10 in the groups with and without caries, respectively (p < 0.001). Significant associations were identified between caries status and all CPQ domains (p < 0.05). Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.86. Test-retest reliability revealed satisfactory reproducibility (ICC = 0.85). The questionnaire proved to be a valid instrument. Construct validity was satisfactory, demonstrating highly significant correlations with global indicators for the total scale and subscales. The CPQ11-14 score was able to discriminate between different oral conditions (groups without and with untreated caries). CONCLUSION: The present study demonstrated that the CPQ11-14 is applicable to children in Brazil. It has satisfactory psychometric properties, but further research is required to evaluate these properties in a population study.

Measuring parental-caregiver perceptions of child oral health-related quality of life: psychometric properties of the Brazilian version of the P-CPQ.

The Parental-Caregiver Perceptions Questionnaire (P-CPQ) is an instrument that assesses a parent's or a caregiver's perceptions regarding the impact of children's oral health status on quality of life. The aim of this study was to evaluate the psychometric properties of the Brazilian version of the P-CPQ. Following translation and cross-cultural adaptation, the P-CPQ was tested on 123 parents and caregivers of children between 11 and 14 years of age with dental caries and malocclusions. The parents/caregivers were recruited at dental clinics of the Federal University of Minas Gerais, where their children were receiving dental care. Psychometric properties were assessed through internal consistency, test-retest reliability, construct validity and discriminant validity. The mean P-CPQ score was 13.01 (SD=12.14) for the dental caries group and 16.57 (SD=13.13) for the malocclusion group. Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.84. Test-retest reliability revealed satisfactory reproducibility (ICC=0.83). Construct validity was satisfactory, demonstrating significant correlations between global indicators and the total scale. The P-CPQ score was able to discriminate between different parental/caregiver perceptions of oral conditions in their children (dental caries and malocclusion). The results for the Brazilian version of the P-CPQ confirm that this questionnaire is a reliable and valid instrument to assess parental perceptions on the impact that oral health status has on children's life quality.

O Parental-Caregiver Perceptions Questionnaire (P-CPQ) é um instrumento que avalia a percepção do pai/responsável a respeito do impacto da saúde bucal da sua criança na qualidade de vida da mesma. O objetivo do estudo foi avaliar as propriedades psicométricas da versão brasileira do P-CPQ. Após a tradução e adaptação transcultural, o P-CPQ foi testado em uma amostra de 123 pais/responsáveis de crianças com idade entre 11-14 anos com cárie dentária e maloclusão. Os pais/responsáveis foram selecionados das clínicas dentárias da Universidade Federal de Minas Gerais, onde as crianças recebiam atendimento odontológico. As propriedades psicométricas foram avaliadas através da consistência interna, confiabilidade teste-reteste, validade de constructo e validade discriminante. O escore médio do P-CPQ foi 13,01 (dp=12,14) para o grupo com cárie dentária e 16,57 (dp=13,13) para o grupo com maloclusão. A consistência interna foi confirmada pelo coeficiente alfa de Cronbach de 0,84. A confiabilidade teste-reteste revelou satisfatória reprodutibilidade (ICC=0,83). A validade de constructo foi satisfatória, demonstrando correlações significativas entre os indicadores globais e a escala total. O escore do P-CPQ foi capaz de discriminar diferentes percepções dos pais/responsáveis sobre as condições bucais de suas crianças (cárie dentária e maloclusão). Os resultados da versão brasileira do P-CPQ confirmam ser este um questionário válido e confiável.
