Oral injuries in children presenting to a Japanese pediatric emergency room

Insights
Children with foreign objects in their mouth are more likely to sustain severe oral injuries and require hospitalization. Parents should be educated on preventing children from moving with objects in their mouth to reduce oral injury risks.
Area of Science:
- Pediatric Emergency Medicine
- Oral and Maxillofacial Surgery
- Childhood Injury Prevention
Background:
- Oral injuries are frequent in children, yet research on foreign object involvement is scarce.
- This study investigated oral injury patterns in children with and without foreign objects in the mouth presenting to a pediatric emergency room.
- The study aimed to compare injury characteristics and outcomes based on the presence of foreign objects.
Purpose of the Study:
- To compare oral injury patterns in children with and without foreign objects in the mouth.
- To analyze the impact of foreign objects on injury severity and medical resource utilization.
- To identify common mechanisms and locations of oral injuries in pediatric patients.
Main Methods:
- Retrospective analysis of pediatric patients with oral injuries treated at a Japanese emergency room (ER) from 2011-2012.
- Data collected included injury mechanism, associated objects, procedures, and disposition (hospitalization/discharge).
- Comparison of injury patterns and outcomes between children with and without foreign objects in the mouth.
Main Results:
- 319 children were analyzed; median age was 26 months.
- Falls (tumbles) were the most common injury mechanism (50%).
- Children with foreign objects (22%, most commonly toothbrushes) had higher rates of posterior oral injuries, required more imaging, and were more likely to be hospitalized (P < 0.001).
Conclusions:
- Falls are the leading cause of pediatric oral injuries.
- The presence of foreign objects in a child's mouth significantly increases the need for medical resources.
- Preventive strategies should emphasize parental education regarding the risks of children moving with objects in their mouths.
Background:
Oral injuries are common among children, but studies on oral injury according to the presence of foreign objects in the mouth are limited. The aim of this study was to compare injury patterns and their effects in children presenting to a Japanese pediatric emergency room (ER) with and without foreign objects in the mouth.
Methods:
Children who were brought to the ER at Tokyo Metropolitan Children's Medical Center with oral injuries between 1 January 2011 and 31 December 2012, were included. Information regarding mechanism of injury, object related to injury, required procedure, and disposition (i.e. placement after ER evaluation: hospitalization or discharge) was collected. Injured subjects with and without foreign objects in the mouth were compared.
Results:
Three hundred and nineteen subjects were included in analysis. Median age was 26 months. Labial mucosa, tongue, buccal mucosa, and teeth were major locations of injury. Tumble (i.e. fall from standing) was the leading mechanism of injury (50%). Seventy-one subjects (22%) were holding foreign objects in the mouth when injury occurred. A toothbrush was the most common object (31%). Subjects with foreign objects in the mouth were more likely to injure the posterior parts of the mouth, and to require imaging (P = 0.04) and hospital admission (P < 0.001). This was also the case for children with injury due to tumble.
Conclusions:
Tumble (i.e. fall from standing) was the most common mechanism of injury. Furthermore, requirement for medical resources increased if children had foreign objects in their mouth. Preventive measures should focus on educating parents about the dangers associated with children moving around while holding objects in the mouth.

Burn Injuries
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
