Dental injuries usually affect one or two of the anterior teeth, and especially
the maxillary central incisors. The aim of the experimental study was to radiographically
evaluate the effect of both Emdogain with and without high power
Diode laser irradiation Emdogain with and without high power Diode laser irradiation
on replanted teeth of rats teeth of rats after extended extra oral dry time.
Material and methods: The study was conducted on extracted maxillary incisors of 42
adult male Albino rats weighing 160–250 g. The rats were assigned to three groups 14
rats in each, then replanted after 75 minutes as follow ; Group I (Control group) no treatment
for the root surface was performed on the extracted upper right central incisors and
alveolar wound before their replantation. Group II (EMD) Emdogain was applied on
root surface and alveolar wound. Group III Diode laser then Emdogain were applied
on root surface and alveolar wound. Replantation was done then splinting of teeth. Half
of each group was euthanized after 4 weeks, while the other half after 8 weeks. The jaws
were dissected out for radiographic examination using standardized periapical technique.
Results: The radiographic analysis showed that the alveolar crest bone density in group < br />III was the highest and less in the group II, while the least density was in the group I.
Conclusion : Application of EMD to the root surface has limited inductive effects on
bone while using EMD with Diode laser leads to better PDL healing and formation of
bone in comparison to using EMD only or without treatment of root surface.
