This document discusses dental trauma to primary teeth from extrusion and intrusion injuries. Extrusion involves partial displacement of a tooth from its socket, leaving the alveolar bone intact. Intrusion is more severe, with displacement of the tooth into the alveolar bone and comminution of the socket. Diagnosis involves visual examination and radiographs. Treatment depends on the severity of displacement and root development, and may include repositioning, extraction or monitoring for spontaneous re-eruption. Follow-up care including soft diets and hygiene instructions are also outlined.

- 1. Fahimeh Vaziri DENTAL TRAUMA TO PRIMARY TEETH Extrusion & Intrusion
- 2. Primary Teeth: Extrusion Partial displacement of the tooth out of its socket partial or total separation of the periodontal ligament loosening and displacement of the tooth. The alveolar socket bone remains intact. axial displacement protrusive or retrusive orientation

- 8. Primary Teeth: Extrusion Diagnostic signs Radiographs recommended occlusal exposure: evaluate the size of the displacement rule out the presence of a root fracture.
- 9. Primary Teeth: Extrusion Treatment Guidelines The treatment choice should be based on the: Degree of displacement Mobility Root formation Ability of the child to cope with the emergency situation.
- 10. Primary Teeth: Extrusion Treatment Guidelines For minor extrusion (< 3mm) in an immature developing tooth, either careful reposition the tooth or leave the tooth for spontaneous alignment.

- 24. Primary Teeth: Extrusion Patient instructions Soft food for 1 week. Good oral hygiene. Brush with a soft brush after every meal and apply chlorhexidine 0.1 % topically to the affected area with cotton swabs twice a day for one week. Parents should be further advised about possible complications that may occur, like swelling, dark discoloration of the crown, increased mobility or fistula. Children may not complain about pain; however, infection may be present and parents should watch for signs of swelling of the gums and bring the child in for treatment.
- 25. Primary Teeth: Extrusion Follow-up Clinical control after 1 weeks. Clinical and radiographic control at 6-8 weeks, 6 months, and 1 year.
- 26. Primary teeth: Intrusion Displacement of the tooth into the alveolar bone. This injury is accompanied by comminution or fracture of the alveolar socket.
- 30. Primary teeth: Intrusion Visual signs Displaced axially into the alveolar bone The tooth may disappear completely in the tissues Penetration of the tooth into the nasal cavity can be diagnosed by bleeding from the nose or simple observation of the nostril.
- 31. Primary teeth: Intrusion Diagnostic signs
- 34. Primary teeth: Intrusion Diagnostic signs Radiographs recommended: An occlusal or periapical exposure If the tooth is totally intruded an extra-oral lateral exposure may be indicated to make sure that the tooth has not penetrated the nasal cavity
- 35. Primary teeth: Intrusion Treatment Spontaneous eruption If the apex is displaced toward or through the labial bone plate, the tooth should be left for spontaneous repositioning. In order to evaluate re-eruption, the degree of intrusion should be assessed by measuring the distance between the incisal edge of the intruded tooth and that of adjacent unaffected teeth. Extraction If the apex is displaced into the developing tooth germ the tooth should be extracted to minimize the damage done to the permanent successor.
- 50. Primary teeth: Intrusion Patient instructions Soft food for 10-14 days. Good oral hygiene. Brush with a soft brush after every meal and apply chlorhexidine 0.1 % topically to the affected area with cotton swabs twice a day for one week. Parents should be further advised about possible complications that may occur, like swelling, dark discoloration of the crown, increased mobility or fistula. Children may not complain about pain; however, infection may be present and parents should watch for signs of swelling of the gums and bring the child in for treatment. Inform the parent about possible complications in the development of the permanent successor, especially following intrusion injuries sustained in children under 3 years of age.
- 51. Primary teeth: Intrusion Follow-up Clinical control after 1 week. Clinical and radiographic control at 3-4 weeks, 6-8 weeks, 6 month, 1 year and yearly clinical and radiographic control until eruption of the permanent successor.
