Improving the Quality of Dental Trauma Care: Two Cases
Dr. Raymond Lee, Chief of Dentistry at the London Health Sciences Centre, spoke with Dr. John O’Keefe about some common mishaps occurring when treating children with traumatic dental injuries.
Dr. Lee has learned from experience that assumptions can sometimes lead to increased pain and less desirable outcomes for young patients.
Dental trauma, including fractured teeth, are frequent in young children that have not gained their balance when learning to walk for example. As such, these young children will present frequently with injuries ranging from slight extrusion to complete avulsion of the teeth as the primary teeth have short roots and the bones are still soft. In contrast, older children with permanent teeth presenting with dental trauma will usually suffer from fractured teeth. The permanent teeth have longer roots and the bone surrounding them is stronger and as such, the forces sustained during injury results in coronal fractures.
What to look for
- Do not assume that teeth or pieces of teeth are not present because they are not visible.
- Radiographs are useful to help rule out intrusion, displacement of pieces of teeth in the soft tissue.
- If young children present with avulsed teeth and they cannot be found and conventional dental radiographs do not show they are intruded or displaced in the hard or soft tissue of the oral cavity, a chest X-ray may be indicated to rule out aspiration.
- Oral lacerations should be carefully examined to ensure fractured pieces of teeth are not embedded in them.
Remember, the overall goal of our treatment is to improve the quality of life and the outcome of treatment in our patients.
