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

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.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate the effects of a fluoride releasing orthodontic primer on demineralization adjacent to brackets. Twenty-two patients were recruited for this study. One premolar was randomly chosen as the experimental tooth, the contralateral tooth was the control. Teeth were visually analyzed for white spot lesions (WSLs). Knoop microhardness was used to determine hardness. Visual examination results showed no significant difference in the number of WSLs observed between Opal Seal and Transbond XT over the duration of this study. Solid conclusions could not be drawn from the results of microhardness testing. Therefore, it cannot be concluded that there is a difference in enamel hardness between Opal Seal and Transbond XT. However, prior to 90 days, teeth showed a significant difference in WSLs. Suggesting a protective effect of Opal Seal that diminished with time. Future studies are necessary to determine the clinical performance of this product.

Available in PDF, EPUB and Kindle. Book excerpt: The evolution of orthodontic materials in the past 5 decades has been a unique progress curve characterized by periods of intense activity with many developments followed by long quiescent intervals. An example of the delay in adopting the advances in dentistry might well be illustrated by the acid-etching technique, which was introduced in the mid 1950s1 and became universally accepted in the 1960s. It took more than a decade for this practice to become standard procedure in orthodontics on a large scale. Infact, orthodontic bonding has advanced more in last 10 years than previous 25. In the past decade, we have witnessed unprecedented progress in bonding to enamel with various materials techniques and auxiliaries involving glass ionomer bonding, self-etching primers, and new, powerful light-curing sources, along with self-ligating brackets and a different treatment concept, the Invisalign technique.

This book was released on 2019 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: To evaluate the efficacy of a fluoride-containing orthodontic primer in preventing demineralization adjacent to brackets and compare the quality of enamel on tooth surfaces that received interproximal reduction (IPR). Methods: Patients at the VCU Orthodontic clinic, 10 years and older, who consented to orthodontic treatment involving extraction of at least 2 premolars were recruited to this split-mouth randomized controlled trial. Brackets were bonded to premolars using one of two primers, Opal®Seal"!or Transbond"!T. IPR was performed, and the fluoride-containing primer was applied to the randomly selected experimental tooth. Extracted teeth were analyzed visually and lesion depths were calculated using micro-CT imaging to note the presence and extent of demineralization. The prevalence and depth of lesions were compared using Fisher's Exact test and Wilcoxon Signed-Rank Test, respectively. Results: A total of 18 teeth from 6 subjects were included in the following analyses. Micro-CT analysis revealed lesions on 89% of teeth treated with Opal®Seal"!compared to 67% with Transbond"!T, but this difference was not statistically significant (p-value=0.5765). There was also no statistically significant difference between the depths of the lesions (p-value=1.00), handedness (p-value=0.5765), hygiene (0.7804), or time in the mouth (p-value=0.5601). Visual exam showed no association with treatment (p-value=1.00), handedness (p-value=1.00), hygiene (p-value=0.1373), or the time the teeth were in the mouth (p-value=0.2987). The fluoride-containing primer also seemed to have no effect on the quality of the enamel on teeth treated with IPR. Conclusion: Fluoride-containing primers may not be effective for preventing demineralization on teeth treated with orthodontic appliances.

This book was released on 2017-06-15 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The only book to cover adhesion in pharmaceutical, biomedical and dental fields The phenomenon of adhesion is of cardinal importance in the pharmaceutical, biomedical and dental fields. A few eclectic examples will suffice to underscore the importance/relevance of adhesion in these three areas. For example, the adhesion between powdered solids is of crucial importance in tablet manufacture. The interaction between biodevices (e.g., stents, bio-implants) and body environment dictates the performance of such devices, and there is burgeoning research activity in modifying the surfaces of such implements to render them compatible with bodily components. In the field of dentistry, the modern trend is to shift from retaining of restorative materials by mechanical interlocking to adhesive bonding. The book contains 15 chapters written by internationally-renowned subject matter experts and is divided into four parts: Part 1: General Topics; Part 2: Adhesion in Pharmaceutical Field; Part 3: Adhesion in Biomedical Field; and Part 4: Adhesion in Dental Field. The topics covered include: Theories or mechanisms of adhesion; wettability of powders; role of surface free energy in tablet strength and powder flow behavior; mucoadhesive polymers for drug delivery systems; transdermal patches; skin adhesion in long-wear cosmetics; factors affecting microbial adhesion; biofouling and ways to mitigate it; adhesion of coatings on surgical tools and bio-implants; adhesion in fabrication of microarrays in clinical diagnostics; antibacterial polymers for dental adhesives and composites; evolution of dental adhesives; and testing of dental adhesive joints.

Download or read book Oral Biofilms and Modern Dental Materials written by Andrei Cristian Ionescu and published by Springer Nature. This book was released on 2021-04-01 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date perspective on oral biofilms and dental materials, equipping readers with a sound understanding of their mutual interactions. Experts from across the world comprehensively describe the main strategies that can be followed when designing modern bioactive and biomimetic dental materials, bearing in mind the goal of reducing the occurrence of pathological conditions such as secondary caries and peri-implantitis. The background to the book is the rapid expansion in the use of nanotechnologies and modern techniques to achieve levels of performance of dental materials that were unthinkable even a few years ago. Whereas conventionally dental materials have been regarded as inert, an important paradigm shift is underway: now, these materials are being conceived as bioactive and biomimetic. Modern dental materials can produce a response by interacting positively both with the host and with the biofilm permanently colonizing hard and soft tissues of the oral cavity. These materials increasingly mimic the behavior of the tissues that they are replacing. In documenting the latest knowledge in the field, this book will be of value for both scientists in the fields of nanotechnology, biofilms and dental materials and interested clinicians.

Download or read book Dental Composite Materials for Direct Restorations written by Vesna Miletic and published by Springer. This book was released on 2017-11-25 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers both basic scientific and clinically relevant aspects of dental composite materials with a view to meeting the needs of researchers and practitioners. Following an introduction on their development, the composition of contemporary composites is analyzed. A chapter on polymerization explains the setting reactions and light sources available for light-cured composites. The quality of monomer-to-polymer conversion is a key factor for material properties. Polymerization shrinkage along with the associated stress remains among the most challenging issues regarding composite restorations. A new classification of dental composites is proposed to offer more clinically relevant ways of differentiating between commercially available materials. A review of specific types of composites provides an insight into their key issues. The potential biological issues of dental composites are reviewed in chapters on elution of leachable substances and cariogenicity of resin monomers. Clinical sections focus on material placement, finishing procedures, and the esthetics and clinical longevity of composite restorations. Bonding to tooth tissues is addressed in a separate chapter, as is the efficiency of various composite repair methods. The final chapter discusses future perspectives on dental composite materials.
