Factors associated with the survival of primary maxillary anterior teeth after intrusive luxation: a retrospective longitudinal study

PURPOSE

To evaluate the survival rate of primary maxillary anterior teeth following intrusive luxation and identify associated factors.

METHODS

A retrospective longitudinal study was conducted at a primary dental trauma centre using 88 dental records of children with intrusive luxation between 2007 and 2018. The variables of interest were time the tooth remained in the alveolus, degree of intrusion, accentuated overjet, lip protection, visible plaque, compromised germ of the permanent successor, clinical signs of infectious and inflammatory processes, endodontic treatment, pulp canal obliteration, sex, age at the time of trauma, family income, mother's schooling, and immediate care. Descriptive, bivariate, and Cox regression analyses were performed (p < 0.05; 95% CI).

RESULTS

The 88 dental records of children with intrusive luxation included 128 teeth. Survival rate throughout the follow-up period was 65.6% (n = 84). Age older than three years and eight months (HR 2.28; 95% CI 1.04-4.99; p = 0.039), the development of an infectious process (HR 3.51; 95% CI 1.39-8.86; p = 0.008), development of an inflammatory process (HR 2.35; 95% CI 1.17-4.71; p = 0.016) and compromised germ of the permanent successor (HR 4.38; 95% CI 1.99-9.61; p < 0.001) were associated with a lower survival rate of intruded primary maxillary anterior teeth.

CONCLUSION

The survival rate during the follow-up period of intruded primary maxillary anterior teeth was considered high. A significantly lower survival rate was associated with age, the occurrence of an infectious process and inflammatory process, and the compromised germ of the permanent successor.

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 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.

Family Impact Scale (FIS): psychometric properties of the Brazilian Portuguese language version

AIM

Evaluate the psychometric properties of the Brazilian version of the Family Impact Scale (FIS).

METHODS

Following translation and cross-cultural adaptation, the FIS was tested on 123 parents-caregivers of children between 11 and 14 years of age with dental caries and malocclusions. The parents were recruited from the Paediatric Dental and Orthodontic clinics where their children were receiving dental care. Psychometric properties were assessed through internal consistency, test-retest reliability, construct validity and discriminant validity.

RESULTS

The mean FIS score was 6.97 (SD 7.81) for the dental caries group and 7.25 (SD 7.70) for the malocclusion group. The FIS score was unable to discriminate different family impact caused by children's oral health conditions. Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.79. Test-retest reliability revealed good reproducibility (ICC 0.83). Construct validity was good, demonstrating highly significant correlations between parent's perceptions regarding the overall wellbeing indicator for their children and the total FIS and subscales. Financial burden demonstrated no significant correlation with global indicators.

CONCLUSIONS

Overall psychometric results for the Brazilian version of the FIS confirm it as a reliable, valid questionnaire for assessing the family impact caused by children's oral conditions.

Measuring parental-caregiver perceptions of child oral health-related quality of life

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.

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 (CPQ_11–14) 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 CPQ_11–14 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 CPQ_11–14 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 CPQ_11–14 score was able to discriminate between different oral conditions (groups without and with untreated caries).

Conclusion

The present study demonstrated that the CPQ_11–14 is applicable to children in Brazil. It has satisfactory psychometric properties, but further research is required to evaluate these properties in a population study.
