Effect of pine bark extract on bond strength of brackets bonded to bleached human tooth enamel

Abstract

So, as a natural antioxidant and less hazardous, clinicians can choose pine bark solution instead of sodium ascorbate.

Effects of Antioxidants on the Shear Bond Strength of Orthodontic Brackets Bonded to Bleached Human Teeth: An In Vitro Study

“…The sample size was determined by using data from previous studies. 1,8,13 A nonprobability purposive sampling technique was used. Sample power analysis designated that 12 teeth per group would result in an 89% chance of obtaining significance at the 0.05 level.…”

“…6,7 Compromised bond strength between the adhesive and bleached teeth has been documented in many studies. 1,3,[8][9][10][11][12][13][14][15] Delaying treatment after bleaching is not always practical, as many patients who have traveled from distant areas or have other commitments may require rapid treatment. To avoid these delays, application of various antioxidants either in gel or solution form has been proposed and investigated in many studies.…”

“…[8][9][10][11][12][13][14][15] The efficiency of sodium ascorbate (SA) in reversing the reduced bond strength in bleached enamel has been proven in many studies, [11][12][13][14][15] although few studies have indicated that SA was ineffective when applied for 10 minutes. 9,10 Other antioxidants, such as 10% α-tocopherol, 9 Aloe vera, 12 pine bark extract, 13 and grape seed extract, 14 have also shown effectiveness in reversing the bond strength reduction in bleached enamel. A few recent studies reported that 10% green tea (GT) had a satisfactory effect in reversing the SBS reduction in bleached enamel after an application time of 60 minutes to 2 hours.…”

Antioxidants In Dentistry: Review Of Literature

“…In bracket bonding, to increase bond strength values ascorbic acid solutions that were hard to prepare were used. In a recent study, it was reported that the usage of pine bark extract solution could be used instead of ascorbic acid solution [18]. For maxillary expansion, there are several studies researching the effect of antioxidant agents on bone formation or maturation.…”

“…In orthodontics, similar agents can be used to increase bond strength of brackets [17,18]. In bracket bonding, to increase bond strength values ascorbic acid solutions that were hard to prepare were used.…”
