Abstract

Aim: This study seeks to ascertain if nanohydroxyapatite laser treatment can preserve alveolar bone width following tooth extraction. Materials and methods: After selecting thirty patients, a random allocation among three equal groups was conducted. In group I, the empty socket was sealed with a bioresorbable collagen membrane lacking a grafting material following tooth extraction. In group II, nanohydroxyapatite was introduced into the socket post-tooth extraction, followed by placing a bioresorbable collagen membrane over the graft, which was subsequently sutured. In group III, nanohydroxyapatite was introduced into the socket post-extraction, and a bioresorbable collagen membrane was applied over the grafting material and sutured. Subsequently, low-level 660 nm laser therapy (LLLT) with a power of 25 mW and duration of 120 seconds was administered thrice weekly for 2 weeks. The alveolar bone's breadth was assessed. by CBCT immediately post-surgery, as well as at 3 months and 6 months thereafter.
Results: The NHA and LLLT groups exhibited a minimal reduction in width measures.
Conclusion: Low-level 660 nm laser therapy (LLLT) to alveolar sockets decreased bone resorption six months post-bone grafting by NHA.
