Summary of Article: This study’s goal was to evaluate the epidemiological aspects of the intrusive injuries in primary teeth: extent, severity, provided treatment and complications.
Study was carried out at the Department of Paediatric and Preventative Dentistry, Faculty of Dentistry, University of Belgrade, Serbia. Patient included in the study attended the clinic in a period from July 1, 2002 to July 1, 2008. 70 children were included in the study with 102 teeth involved. The mean time from injury until professional help was 2 days, only 17 children (24%) sought professional care with in 12 hours after the injury.
Conclusion/ Key points
1. Injuries occurred in children 2 years or younger, males slightly higher then females.
2. Fall was the most common injury
3. Mild intrusion was most common
4. Spontaneous re-eruption occurred in most intruded injuries, mild (<2mm) intrusion took less time to erupt compared to moderate(2-4mm)/severe(>4mm) intrusion.
5. Most common complication was crown discoloration. Complications occurred less often in mildly intruded teeth than in moderate and severe intrusions.
6. Complications were found in 25 of 102 intruded primary teeth. Color change appeared as the most common complication. Tooth discoloration is a frequent post-traumatic complication
7. Clinical studies show that in most cases there were no radiographic or clinical signs of infection of discolored primary teeth. A majority of these teeth exfoliate at the expected time, and there is usually no need for the treatment.
8. Further clinical evaluation with larger number if permanent successors of intruded primary teeth is needed to confirm the results in this study.
