Summary
Dental fragments in lips result from teeth transfixing the lip and fracturing on hard object impact. Many lip lacerations were treated without detecting these embedded dental fragments.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Traumatology
Background:
- Dental fragments embedded in lips present a diagnostic challenge.
- Lip lacerations involving foreign bodies are often treated without complete identification.
Purpose of the Study:
- To analyze the cause, location, and dental relationships of lip fragments.
- To investigate the mechanism of tooth fracture leading to lip impaction.
Main Methods:
- Retrospective analysis of 15 cases with dental fragments in the lips.
- Examination of injury cause, site, and relation to anterior teeth.
Main Results:
- All cases involved lip lacerations from mucosa to skin.
- A hypothesis was supported where teeth transfixed the lip, fracturing on skin emergence against a hard object.
- Foreign bodies were frequently missed during initial wound repair in general hospitals.
Conclusions:
- Dental fragments in lips often result from tooth transfixation and fracture.
- Delayed detection of dental fragments can occur during initial medical management of lip injuries.
