Background/aimThe impact of traumatic dental injuries (TDI) in the primary dentition on oral health-related quality of life indicates the need for the planning of prevention strategies. The aim of this study was to assess whether anthropometric characteristics in early life are associated with TDI by preschool age.Materials and methodsA birth cohort was recruited from the public healthcare system in the city of Porto Alegre, Brazil. Socio-demographic variables, type of birth, head circumference, weight, and length were collected at birth (WHO standards). Head circumference, body mass index for age, and height for age were collected at 12 months. TDI (Andreasen criteria) at three years of age (n = 458) were recorded by two examiners who had undergone training and calibration exercises. Multivariable analysis was carried out with Poisson regression with robust variance.ResultsA total of 31.0% of the children (142/458) exhibited TDI at three years of age. In the final model, the risk of TDI was 47% higher among children with a smaller head circumference upon birth and nearly 60% higher among those who were overweight/obese at 12 months of age (RR: 1.58; 95% CI: 1.15-2.17). The risk of TDI was also significantly higher among boys (RR 1.50; 95% CI: 1.13-2.00), but the outcome was not significantly associated with socioeconomic variables or other anthropometric variables.ConclusionOverweight/obesity in early life is a risk factor for TDI in preschool children.

Background/aim: Enamel fractures are the most common type of traumatic dental injury (TDI) in children and adolescents. Recognizing the impact of these fractures on oral health-related quality of life (OHRQoL) could contribute to the establishment of treatment protocols. The aim of this study was to assess and quantify the impact of enamel fractures on overall OHRQoL and domain scores in adolescents.Materials and Methods: A cross-sectional study was conducted with 775 adolescents aged 11 to 14 years in the city of Santo Ângelo in southern Brazil. Sociodemographic variables were collected from parents/caregivers using a structured questionnaire. The adolescents answered the Child Perceptions Questionnaire (CPQ11-14 ). Physical examinations were performed by an examiner who had undergone training and calibration exercises for the investigation of TDI (Andreasen criteria), dental caries (WHO criteria), and malocclusion (Dental Aesthetic Index). Data analysis involved Poisson regression with robust variance.Results: The prevalence of TDI was 11.9% and enamel fractures accounted for 79.3% of all injuries. In the multivariate analysis, adolescents with enamel fractures had 29% higher CPQ11-14 scores (worse OHRQoL) than those without TDI, even after adjustment for sociodemographic and clinical variables (mean ratio = 1.29; 95% CI: 1.09-1.53; P = .003). Enamel fractures exerted a negative impact on the functional limitation, emotional well-being, and social well-being domains.Conclusions: Enamel fractures exert a negative impact on the OHRQoL of adolescents, suggesting that subjective measures should be incorporated in the evaluation of patients with this traumatic injury.

Aim: To explore the profile of articles on traumatic dental injuries (TDI) in the primary dentition published in Dental Traumatology in the last 15 years using bibliometric analysis.Methods: Three researchers read all titles and abstracts of articles published in Dental Traumatology between 2000 and 2014 (excluding editorials and letters) and selected all articles on TDI in the primary dentition. The articles were categorized according to year of publication, country in which the study was conducted, study design, and topics addressed. Divergences were resolved by consensus between the researchers.Results: Among a total of 1257 articles published, 98 were initially excluded. Among the remaining 1159 articles, 152 (13.1%) focused on TDI in the primary dentition. The articles were conducted in 29 countries, with Brazil (38.8%) and Turkey (11.8%) accounting for the largest numbers. Cross-sectional studies (36.2%) and case report/case series (33.6%) were the most frequent study designs. Only two systematic reviews were published. The most commonly addressed topics were frequency/etiology/associated factors (36.8%), treatment (30.9%), and prognosis (19.7%). Among the articles addressing treatment, two-thirds were case reports or case series. The effects of TDI in primary teeth on their permanent successors were addressed in 20.4% of the articles (31/152).Conclusions: The number of articles on TDI in the primary dentition has increased, but remains low. The evaluation of study designs and topics addressed identified gaps that could contribute to the development of new studies on TDI in the primary dentition, especially cohort studies that evaluate risk factors, prognosis, and treatment.
