AI Article Synopsis
- A study was conducted to assess the link between occlusal characteristics and dental trauma in preschool children aged 3-5 in Brazil, using a sample of 200 matched cases and controls.
- The results indicated that anterior open bite was significantly associated with an increased risk of dental trauma (OR = 3.80), while other occlusal factors like maxillary anterior crowding and overjet showed less consistent relationships after adjustments.
- Ultimately, the study concluded that anterior open bite is a key risk factor for dental trauma in young children, regardless of other influencing factors.
Article Abstract
Background/aims: Occlusal features may increase the risk of dental trauma. The aim of the present study was to evaluate the association between occlusal characteristics and the occurrence of dental trauma in preschool children.
Materials And Methods: A population-based case-control study was conducted with a representative sample of 200 children 3-5 years of age enrolled at private and public preschools in the city of Diamantina, Brazil. The case and control groups were matched for gender, age and type of preschool (public or private) at a ratio of 1:1 (100 cases and 100 controls). Independent variables of interest to the study (occlusal characteristics) and potential confounders (sociodemographic characteristics, sucking habits and lip coverage) were investigated. Intra-examiner and inter-examiner kappa values were higher than 0.80 for all oral conditions evaluated. The SPSS 22.0 program was used to analyse the data. Descriptive and univariate analyses as well as simple and multiple logistic regression analyses were performed.
Results: The occlusal feature most strongly associated with trauma was anterior open bite (OR = 3.80; 95% CI: 1.42-10.16). Maxillary anterior crowding (OR = 2.14, 95% CI: 1.00-4.63) and overjet (OR = 1.12, 95% CI: 0.58-2.17) were associated with the occurrence of trauma independently of the confounding variables (sociodemographic characteristics, sucking habits and lip coverage), but these variables lost their significance when adjusted for other types of malocclusion. Anterior open bite remained strongly associated with dental trauma, regardless of confounding variables and other types of malocclusion.
Conclusion: Anterior open bite was the main variable associated with dental trauma in the preschool children analysed independently of the confounding variables and the presence of other malocclusions.

Paroxysmal Sympathetic Hyperactivity (PSH) is a challenging and often underrecognized syndrome, commonly arising after a traumatic brain injury (TBI). Characterized by episodic bursts of heightened sympathetic activity, PSH presents with a distinct constellation of symptoms including hypertension, tachycardia, hyperthermia, and diaphoresis. While the exact pathophysiology remains elusive, current evidence suggests that the syndrome results from an imbalance between excitatory and inhibitory neuronal pathways within the central nervous system, leading to dysregulated autonomic responses.

Mandibular and maxillary fractures are common in small animals and present significant challenges for repair due to the intricate anatomical features involved. This retrospective case series describes a technique for achieving rigid open mouth maxillomandibular fixation using interarch wiring while maintaining correct alignment between the upper and lower teeth with polymethylmethacrylate (PMMA) moulds of the canine teeth for treating maxillomandibular fractures in cats. The study includes a description of the postoperative outcomes and complications encountered.

Objectives: This study aims to compare the clinical performance of 3D printed endocrowns (ECs) and prefabricated zirconia crowns (PZRCs) in restoring pulpotomized primary molars, over 3, 6, and 12 months.
Methods: Thirty pulpotomized mandibular primary molars in 16 children aged 4-8 years were randomized with a 1:1 allocation ratio into two groups: group (A), PZRCs, and group (B), 3D-printed ECs. All restorations were evaluated for esthetic, functional, and biological properties using FDI criteria at 3-, 6-, and 12-month intervals.
