Sustained Release of Calcium Ions &Ph Maintenance from Different Vehicles containing calcium hydroxide- an in vitro study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 5
Abstract
AIM: The aim of the in vitro study is to determine the Sustained Release of Calcium Ions & pH maintenance from different vehicles containing calcium hydroxide using ultraviolet spectrophotometer and pH meter.Material And Methods: The present in vitro study was carried out in Rajah Muthiah Dental College & Hospital, Annamalai University. Thirtysingle rooted human teeth extracted for orthodontic purpose or periodontal purpose were selected to determine the sustained release of calcium ions and pH maintenance from different vehicles containing calcium hydroxide using ultraviolet spectrophotometer and pH meter.The three types of vehicles which were mixed with calcium hydroxide are; An aqueous vehicle (anesthetic solution), viscous vehicle (propylene glycol) and an oily vehicle (olive oil).Results: The results of the study concluded that Olive oil when used as a vehicle exhibited a sustained release of calcium ions from calcium hydroxide for prolonged duration when compared with propylene glycol and anesthetic solution.Conclusion: Calcium hydroxide is the commonly preferred intracanal dressing in endodontics, its therapeutic effect mainly depends on its dissociation into calcium and hydroxyl ions, which in turn depends on the vehicles used.
