In a total of 123 female adult Wistar rats the first upper molar was moved by orthodontics for more than 28 days. This orthodontically stimulated tooth movement was influenced by local application of Cu-salicylate, Cu-indomethacin or epsilon-Aminocapronacid. The application of Cu-salicylate and Cu-indomethacin caused reduced tooth movement, a decrease in osteoclasts in the pressure region of the periodontium, and an increase of hydroxyproline in the desmodont. Generally, the local application of Cu-nonsteroidal antiphlogistics seems to stabilize the experimentally induced tooth movement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
