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: This book is a well-illustrated guide to the iatrogenic effects of orthodontic treatment that provides practical information on orthodontic diagnosis, treatment planning, and post-treatment retention and highlights preventive measures to avoid complaints and lawsuits. It is divided into three parts, on white spot lesions, periodontal deterioration, and external apical root resorption (EARR). The reader will learn a wide variety of invaluable skills and strategies, such as how to minimize the risk of enamel decalcifications as a result of orthodontic treatment; how to deproteinize the enamel surface and bond brackets with hybrid glass ionomer cement; how to avoid lower incisor proclination and still achieve ideal long-term alignment; and how to apply strategies to minimize orthodontically induced EARR. Iatrogenic Effects of Orthodontic Treatment will be an excellent aid for both orthodontists and pediatric dentists.

Available in PDF, EPUB and Kindle. 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.

This book was released on 2015 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction:. During the course of orthodontic treatment, enamel decalcification is a common problem. Demineralized enamel, the precursor to caries formation, can be attributed to fixed orthodontic appliances and prolonged exposure to bacterial plaque. Progression to clinically detectable white spot lesions may occur as early as one month following the placement of orthodontic appliances. Such problems have influenced clinicians to search for a solution. Because fluoride treatment immediately upon debonding is not advocated, clinicians have proposed fluoride treatment and fluoride-releasing materials at the commencement of the therapy. The two new anti-cavity toothpastes, ClinproTM 5000 with 1.1% Sodium Fluoride and ClinproTM Tooth Créme with 0.21% Sodium Fluoride have been shown to be useful in reduction of white spot lesions. Both the Clinpro TM products (3M ESPE) contain fluoride as well as tri-calcium phosphate, which are components naturally found in saliva. The aim of this study is to determine if ClinproTM 5000, ClinproTM Tooth Créme, or MI-Paste Plus has an effect on the formation and resolution of white spot lesions for patients undergoing orthodontic treatment. Methods: Three prospective groups of 40 patients undertaking routine orthodontic treatment were evaluated (total recruitment of 120 subjects). Patients must have their permanent dentition, be 12 years or older, and have not used extensive fluoride regimes before. Patients were chosen if they appear that they would be compliant as judged by the investigator. The selected product was brushed on the teeth by the patient for two minutes, twice daily for a total of 4 months. After brushing, the patients were instructed to expectorate only, not rinse, eat or drink anything for at least 30 minutes. The subjects were observed every 4 weeks. At each visit, 3 intraoral photos were taken (frontal and buccal views) and measurements based on the Enamel Decalcification Index (EDI) will be recorded. The Enamel Decalcification Index was used to determine the number of white spot lesions and caries risk detected in these photographic records. Also, a brushing diary was reviewed. A trained member of the 3M ESPE Clinical Research group did monitor the study by means of visits to the clinic to evaluate patient charts, study data, and study photographs. Results: Altogether, the results provided strong support with regard for ClinproTM 5000 providing superior enamel protection against decalcification when compared to ClinproTM Créme, and MI Paste. Conclusions: The use of ClinproTM 5000, ClinproTM Créme, and MI paste demonstrated less formation of white spot lesions when compared to data in the literature. ClinproTM 5000 had a marginally better affect compared to the other two products.

Available in PDF, EPUB and Kindle. Book excerpt: The development of aesthetically unattractive white spots is a concern for patients undergoing fixed orthodontic treatment. Due to poor oral hygiene during treatment, accumulation of plaque around orthodontic brackets causes bacterial fermentation reactions producing acids that dissolve the mineral enamel. Such dissolution results in white spot formation, an early sign of dental caries. In principal, to inhibit the appearance of these spots during treatment, fluoridated elastomeric o-rings might be employed. Once placed around brackets, these o-rings should release fluoride therapeutically for at least 30 days, after which the orthodontist may replace them. At the present time, such fluoride-releasing o-rings are not available. In this study, model materials for fluoride-releasing elastomeric o-rings were developed. These materials were fluoride-impregnated poly(ethylene-co-vinyl acetate) (PEVA) films. In vitro release studies of these films were conducted, assessing their capacity to deliver fluoride within therapeutic range (1.2 [less than or equal to] [micro]g F/ring/day [less than or equal to] 51.4) for 30-45 days. Optimal sample and experimental parameters, including (1) fluoride loading in the film (wt% F), (2) overcoat thickness, and (3) temperature that provided therapeutic release, were determined. At 37°C, favorable release was observed for the following: (1) films with overcoat thickness of 0.14 mm and fluoride loadings of 3.9 wt% and 5.7 wt% and (2) films with overcoat thickness of 0.27 mm and fluoride loading of 5.7 wt%. These results are important in providing fundamental guidance for the development of o-rings that combat white spot formation among orthodontic patients.
