Book excerpt: The purpose of this study was to compare the rate of fluoride release with time of one non-fluoridated and three fluoride-containing orthodontic bonding materials in distilled water and artificial saliva. Materials tested were: Assure (Reliance, Itasca, IL), Fuji Ortho LC (GC America Inc., Alsip, IL), Python (TP Orthodontics Inc., LaPorte, IN), and Transbond XT (3M, St Paul, MN). Twenty specimens of each material were polymerized and placed in polyethylene tubes. Half the specimens were stored in 1 mL of distilled water and half in 1 mL of unstimulated artificial saliva, at 37C and 100% relative humidity. Fluoride release was measured with an ion-specific electrode. Readings were taken-at 1, 2, 3, 5, 7 and 9 days from time of immersion, then weekly for three weeks and monthly for 5 months. To prevent cumulative measurements, storage solutions were changed 24 h prior to the weekly and monthly readings. Results showed Assure to release the most fluoride, followed by Fuji Ortho LC, Python, and Transbond. The fluoride release rates were greatest during the first days of testing, declining to low but stable levels. The type of storage medium did not dramatically affect fluoride release. Throughout the study, daily fluoride release rates of all three fluoride-containing materials were within the therapeutic range for the reduction of enamel demineralization. The second part of the study tested the twenty samples of Assure for a further two-week period, after exposure to running and still distilled water. Although fluoride release rates declined with time, they were again within the therapeutic range. Release rates were similar in running and still water at all time points.

Available in PDF, EPUB and Kindle. Book excerpt: Enamel demineralization in the form of white spot lesions (WSLs) around fixed orthodontic appliances is a persistent problem in patients with poor oral hygiene. These lesions can form rapidly within 4 weeks of bracket placement. The purpose of this in-vitro study was to investigate the fluoride recharging capability ofa commercially available orthodontic primer used to minimize the development of WSLs in patients. The three groups tested were: OpalSeal (n=20, Ultradent, South Jordan, UT), ProSeal (n=20, Reliance, Itasca, IL) and Transbond XT (control, n=10, 3M Unitek, Monrovia, CA). The samples(5mmin diameter x 1mm in thickness) weresuspended individually in vials filled with 10mL of deionized water usinga fishing line. The baseline fluoride ion release from all of the samples was measured after two weeks of changing the solution every other day. The samples were then randomly divided into two groups, toothbrush or gel. The samples in the toothbrush group were brushed for one minute every day for 7d, with fluoride containing toothpaste (Colgate-Palmolive Company, New York, NY) and placed in a new solution after each brushing. After 7d of brushing the fluoride ion release was measured. The samples in the gel group were immersed in 10mL of acidulated phosphoric fluoride gel (APF) for one minute, following manufacturer0́9s instructions, and then placed in a new vial with 10mL of deionized water. At the end of 24hrs fluoride ion release measurementswere made and the samples were placed individually in a new solution. The solution was changed weekly in the gel group over six weeks to simulate the typical length of time between two orthodontic appointments. A final fluoride ion release measurement was taken of all the discs in the gel group 6 weeks after the fluoride gel treatment. The results of repeated-measures analysis indicated that there were no significant differences between the groups at baseline and after 7d of toothbrushing time points. Opal Seal exhibited a significant increase in fluoride uptake (1.0ppm) after 24hrs of fluoride gel exposure but these levels gradually decreasedover 6 weeks (0.04ppm). Pro Seal and Transbond showed no significant fluoride release after the gel or toothpaste applications. The fluoride-containing primer, Opal Seal, had the ability to be recharged with fluoride ions from APF gel. However, the amount of fluoride released from recharged discs decreased gradually over a 6 weeks of time.

Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (postgraduate) from the year 2008 in the subject Medicine - Dentistry, grade: none, University of Mosul (Dental college), language: English, abstract: Aim: This study aims to measure the amount of fluoride release in deionized water from two composite resins materials (Kerr and Tetric ceram)over period of one month. By using different curing time for curing the composite.Materials and Methods : Two types of composite resin materials were used. They are Tetric ceram and Kerr composite resins divided into five groups for each type of materials used, each group contain ten sample materials and cured with different time of curing which are (20,30,40,50,60) seconds.The samples measured fluoride release after storing in 5ml of deionized water then incubated incubator at 37°C for 24 hours.Results: The amount of fluoride release was affected by the period of curing time. The materials which cured at (20,30,40) seconds gave high amount of fluoride release while the materials which cured at (50,60)seconds gave low amount of fluoride release. Conclusions: The amount of fluoride release from composite resins materials were affected by curing time. There is an increase in the amount of fluoride release by decreasing the period of curing time and decreasing by increasing the period of curing time.

Available in PDF, EPUB and Kindle. Book excerpt: Objective: The purpose of this study was to determine the fluoride recharging capability of Opal Seal, a fluoride releasing orthodontic primer, as compared to Transbond XT, the control. Material and Methods: 1mm x 5mm disks of Opal Seal and Transbond were prepared according to the respective manufacturer's instructions. Initially, the samples were stored in deionized water (DI) for 8 weeks. The samples were then randomly divided into one of two groups: Over-the-counter (OTC) fluoride mouthwash and prescription strength (PS) fluoride mouthwash. The OTC group samples were immersed in 5mL of 0.0219% sodium fluoride containing mouthwash for one minute every day for seven days. The PS group samples were immersed in 5mL of 0.2% sodium fluoride containing mouthwash for one minute. All of the samples were suspended in 5mL fresh DI water and fluoride release measurements were taken at baseline (the end of initial 8 weeks of storage), 24 hours, 3 days, 5 days, 7 days, and 14 days. Results: Opal Seal samples treated with the OTC fluoride mouthwash exhibited significant fluctuation in fluoride ion release across time (p=0.0058). However, there were no statistically significant differences in fluoride ion release between the individual timepoints and baseline. Similarly, Opal Seal samples treated with the PS fluoride mouthwash exhibited significant variation in the fluoride ion concentration across time (p
Download or read book Fluoride Releasing Dental Materials written by Mukhtar Alia and published by LAP Lambert Academic Publishing. This book was released on 2015-03-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes about the fluoride release and recharge abilities of fluoride-releasing dental restoratives, and discuss the current status concerning the prevention or inhibition of secondary caries. Fluoride-containing dental materials show clear differences in the fluoride release and uptake characteristics. Due to the fact that fluoride levels leached from fluoride containing filling materials decreased over time the "recharging" of restoratives with fluoride has been suggested to maintain a continuously increased level of fluoride release. The ability of a restorative material to act as a fluoride reservoir is mainly dependent on the type and permeability of filling material, on the frequency of fluoride exposure and on the kind and concentration of the fluoridating agent.It describes all fluoride releasing dental materials in detail.
