An injury to the tooth supporting structures resulting in increased mobility, but without displacement of the tooth. Bleeding from the gingival sulcus confirms the diagnosis.
- An injury to the tooth supporting structures resulting in increased mobility, but without displacement of the tooth. Bleeding from the gingival sulcus confirms the diagnosis
- Visual signs: Not displaced
- Percussion test: Tender to touch or tapping
- Mobility test: Increased mobility
- Pulp sensibility test: Sensibility testing may be negative initially indicating transient pulpal damage. Monitor pulpal response until a definitive pulpal diagnosis can be made. There will be a positive sensibility test result in about half the cases. The test is important in assessing future risk of healing complications. A lack of response at the initial test indicates an increased risk of later pulp necrosis.
- Radiographic findings: Usually no radiographic abnormalities
- Radiographs recommended As a routine: Occlusal, periapical exposure and lateral view from the mesial or distal aspect of the tooth.
- Usually no need for treatment.
- However, if needed:
- Clean the area with water spray, saline, or chlohexidine
- Suture gingival laceration, if present
- In case of pain related to occlusion, slight grinding of antagonist
- Apply splint, if necessary for comfort. Splinting can also be applied as part of stabilization of adjacent teeth
- Splint removal after 2 weeks
- Clinical and radiographic controls after 4, 6-8 weeks and 1 year. if a normal pulp response is observed, no further follow-up is needed.
- Patient instructions:
- Soft food diet for 1 week
- Good healing following an injury o teeth and oral tissues is dependent in part on good oral hygiene. Brushing with a soft brush and rinsing with chlorhexidine 0.1% is beneficial to prevent accumulation of plaque and debris.
