Evidence that using hyperbaric oxygen improves the success of young permanent tooth re-implantation
|
Clinical Bottom Line: 1. Using hyperbaric oxygen resulted in a high rate of successful re-implantation of young permanent teeth. |

The Study:
Non-blinded randomised controlled trial - intention-to-treat unknown.
The Study Patients: Unclear, but the teeth are described as 'young permanent teeth'.
Control group (N = 69; 69 analysed): Unclear except teeth were re-implanted after being lost.
Experimental group (N = 69; 69 analysed): 100% oxygen breathing at 2.5 ATA for 80 minutes daily for 10 days

Comments:
1. Abstract only available in English. Methodology unclear.
2. Timing of 'successful re-implantation' outcome unclear, but ultimate success at one year given.
3. These figures assume equal numbers of teeth in each group
4. Full translation awaited
