| ABSTRACTBackground: Management of tooth wear from grinding presents a significant clinical challenge .Acrylic night guardsare often used to protect the teeth. The long term objective is to find a simple approach to control tooth wear as analternative to the use of night guards. This in vitro study aimed to assess the effectiveness of three lubricants inreducing enamel wear.Materials and Methods: Thirty two extracted human third molar were selected, randomly assigned in to four groups ofeight teeth each ,teeth were sectioned longitudinally in to two halves (buccal and lingual ),the sectioned specimenswere apposed each other in an electro mechanical wear machine under a load of 3 Kgs. The machine simulatedtooth grinding for (20000) wear cycles. The experiment was repeated for another (20000)wear cycles under fourdifferent conditions: Group I: without using lubricants. Group II: The use of dry lubricant (Calcium Fluoride Ca Fpowder). Group III: The use of Olive -Oil. Group IV: The use of combination of Calcium Fluoride /Olive-Oil slurry. Wearrates of enamel were quantified by weighing the specimens before and after the use of lubricants. Analysis ofvariance ANOVA test was performed between experimental groups to test the differences of wear rates among thefour groups.Results: All three lubricants reduced enamel wear significantly when compared with wearing specimens with outadding lubricants. Wear rates were significantly less for Olive-Oil, and Ca F /Olive- Oil slurry compared with Ca Falone, while there was no significant difference between the use of olive oil alone and the use of Ca F/Olive- Oilslurry.Conclusion: It was confirmed that each of the three lubricants reduced the wear rates of enamel substantially duringtooth grinding when compared with wear rates of enamel without lubricant. This study also confirmed that Olive-Oil isvery effective lubricant.Key words: Enamel wear, lubricant, Olive oil, Calcium Fluoride (Ca F). J Bagh Coll Dentistry 2010; 22(1):14-17. | ||
