Effect of Emdogain and Diode laser Irradiation ‎on ‎Periodontal Healing of Replanted Teeth after ‎Extended Extra ‎‎- Oral Dry time ( An Experimental ‎Study).‎

Abstract

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 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.
