Methods for increasing oral osteogenesis using lipoxin A
The invention provides methods for increasing oral osteogenesis using LXA 4 and its analogs. Methods are also provided for treating or preventing oral disorders that would benefit from increased oral osteogenesis using LXA 4 and its analogs.
1. A method of increasing oral osteogenesis in a subject afflicted with a periodontal disease, the method comprising topically administering a therapeutically effective amount of a lipoxin A 4 (LXA 4 ) analog to the oral cavity of the subject,
wherein the LXA 4 analog is 9,12 benzo-LXA 4 , and
wherein the 9,12 benzo-LXA 4 increases oral osteogenesis in the subject.
2. The method of claim 1 , wherein the periodontal disease is selected from the group consisting of periodontitis, dental plaque-induced gingival diseases; chronic (previously adult) periodontitis; aggressive periodontitis (formerly early-onset, prepubertal, juvenile or rapidly progressive periodontitis); necrotizing periodontal diseases; abscesses of the periodontium; post-operative bacterial infections, alveolar bone loss, and gingivitis.
3. The method of claim 1 , wherein the 9,12 benzo-LXA 4 is formulated in a pharmaceutically acceptable carrier.
4. The method of claim 3 , wherein the pharmaceutically acceptable carrier is selected from the group consisting of gels, mouth rinses, toothpastes, dentifrice, buccal patch, dental fiber, dental tape, chewing gum, food additives, lozenges, tablet, and chewable capsule.
5. The method of claim 1 , wherein the therapeutically effective amount of 9,12 benzo-LXA 4 is an amount that increases oral bone growth and/or reduces oral bone reabsorption.
6. The method of claim 1 , further comprising administering to the subject at least one additional agent that treats periodontal disease.
7. The method of claim 6 , wherein the additional agent is selected from the group consisting of anti-inflammatory agents and antimicrobial agents.
8. The method of claim 3 , wherein the pharmaceutically acceptable carrier is an intraoral delivery device.
9. The method of claim 1 , wherein the LXA 4 analog is encapsulated in a nanoparticle of biologic or synthetic origin.
10. The method of claim 1 , wherein the therapeutically effective amount of 9,12 benzo-LXA 4 is an amount that increases oral osteogenesis by at least 10% relative to not administering the LXA 4 analog.
11. The method of claim 1 , wherein the administering is to a subject undergoing periodontal flap surgery.
12. The method of claim 1 , wherein the administering is to a subject has undergone periodontal flap surgery.
13. The method of claim 11 , further comprising additionally administering a therapeutically effective amount of 9,12 benzo-LXA 4 to the subject one or more times after periodontal flap surgery completion.
