Background/Aims
The literature does not clearly state whether the type of malocclusion is associated with a specific type of trauma and the severity of the injury. Hence, the aim of this retrospective study was to assess the occlusal condition in children with traumatic dental injuries of the primary teeth, and the association between the occlusal characteristics and the type and severity of these injuries.
Material and Methods
Data were collected from records of children treated at a dental trauma center in Brazil over a period of 16 years. The data included age, gender, etiology of the trauma, place of occurrence, number of affected teeth, type of trauma, and injury severity. The occlusal condition was assessed by a trained dentist using photographs of the patients from their first visit. Chi‐square tests and Poisson regression were used for data analyses.
Results
This study included 209 patients, and most were aged between 2‐4 years (50.55%). Multivariate regression analysis showed that children with an anterior open bite had a 47% higher prevalence of severe trauma than those who did not have an anterior open bite, and those with class II canines had a 56% higher prevalence of severe trauma than those with class I and III canines. Children with an anterior open bite had a 46% higher prevalence of injuries affecting multiple teeth than those without an anterior open bite.
Conclusions
Anterior open bite and class II canine relationship were associated with a higher prevalence of severe traumatic dental injury in primary teeth, and anterior open bite was associated with trauma affecting multiple teeth.
BackgroundCohort studies have demonstrated an association between prolonged and/or frequent breastfeeding and early childhood caries (ECC).AimTo investigate the association between prolonged breastfeeding and ECC at 48 months, while considering the interaction between prolonged breastfeeding and ultraprocessed foods (UPF).DesignData from a birth cohort study conducted in southern Brazil were used (n = 3645). Poisson regression was used to evaluate the influence of breastfeeding and UPF consumption on the prevalence and experience of caries. To measure the interaction on the additive scale between breastfeeding and UPF consumption on the prevalence and experience of ECC, the relative excess risk due to interaction (RERI) was calculated.ResultsProlonged breastfeeding was associated with higher prevalence (PR = 1.82; CI:1.59–2.08) and experience (RR = 2.47; CI:1.97–3.10) of ECC. Greater prevalence (PR = 1.16; CI: 1.04–1.30) and experience of ECC (RR = 1.22; CI: 1.00–1.48) were found in children who had high consumption of UPFs. Negative RERIs were observed for the prevalence and experience of ECC (−0.25 and −0.001).ConclusionHigh UPF consumption and prolonged breastfeeding were associated with ECC. No interaction, however, was observed, showing that the two exposures have independent effects. To prevent ECC, policies and programs are needed to support breastfeeding until the age of 2 years and to limit the consumption of UPF.
Objective: To translate and perform the cross-cultural adaption of the CD:H scale for use in Paediatric Dentistry in Brazilian Portuguese language. Material and Methods: The translation and cross-cultural adaptation of the CD: H was carried out in four stages: 1) translation of the instrument; 2) reverse translation (back translation); 3) cross-cultural adaptation, and 4) face validation. Face validation consisted of the evaluation of 30 subjects from the target population. A pilot study was conducted with 15 children aged 5-10 years treated at a university dental clinic and their drawings were analysed by two dentists. Data were analysed using Stata 12.0. Results: In the face validation, most items were understood; however, some words were changed, and terms were included to identify the dental environment. Good reproducibility was obtained: inter-examiner reliability was 0.9647 and intra-examiner reliability was 0.9619 for examiner A and 0.8260 for examiner B. Conclusion: The Brazilian version of the CD:H scale is a useful tool for dentists, helping identify children's emotions and being enjoyable for them.
