Dr. Priya K presently lives in Bangalore. Orthodontic band has been in clinical use for more than 100 years. In spite of the wide spread use of direct bonded brackets and tubes in clinical orthodontics, the conventional band still plays an important role in fixed appliance therapy.Although bonding of orthodontic tubes to the teeth is receiving much current interest in the form of indirect bonding, the vast majority of buccal attachments are still being cemented using stainless steel bands and conventional cements, considering the force levels in the posterior region. Enamel demineralization under orthodontic bands is a serious, but a common problem to all orthodontists. White spot formation or enamel decalcification can occur whenever bacterial plaque is retained on enamel surface for a prolonged period.By the presence of fixed appliance the efficiency of home prophylactic procedure is greatly reduced and there is a need for protection of adjacent enamel surface. Inadequate bonding strength of dental cement, seal break down, solubility of the currently used dental cements in oral fluids and poor oral hygiene all contribute to the initiation of decalcification.Several studies in the past have investigated the chemical composition of various cements, their physical and chemical properties and their application as well as use in restorative dentistry. The retention of orthodontic bands to the tooth surface is important to ensure fixed appliance therapy. Numerous agents have been used to retain orthodontic bands. Guttapercha, zinc oxide eugenol, zinc polyacrylate cement, zinc polycarboxylate cement, resin based cements, zinc silicophosphate and black copper cement have all been investigated. More recently attention has been focused on glass ionomer cement.Sand blasting of the metal surface improves retention by roughening, thereby increasing the surface area and providing a potential for a degree of mechanical attachment . It not only increases the retentive area of the band luting surface, but also removes contaminants and thins the stainless steel oxide layer leaving a more firmly attached layer for bonding.This technique of air abrasion or sand blasting was introduced in 1950's. It uses a high-speed stream o f aluminum oxide particles propelled by compressed air. Although initially reintroduced as a method to roughen the surface of any dental materials before cementation, it is routinely used in cast metal restoration to enhance the bond strength; more recent marketing includes its application to orthodontics to roughen the internal surface of the bands and bracket bases.This in-vitro study is undertaken to explore and emphasize the possibilities of increasing bond strength with newer hybrid cement s and subsequently sand blasting the inner surface of the bands to enhance bond strength.

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 2004 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conditioning and priming of unground enamel using conventional acid etchants and bonding resins has been recommended for effective bonding in orthodontics. The use of the newer single-step self-etching adhesives which etch, prime and apply the resin bonding agents simultaneously without rinsing, has been increasing in popularity. The purpose of this study was to compare the shear-peel bond strength and the amount of adhesive remaining on the tooth after debonding of a traditional two-step etch and prime technique, with a single-step alternative, when used with a composite resin adhesive system and a resin-modified glass ionomer cement system.

Available in PDF, EPUB and Kindle. Book excerpt: Aesthetic restorative materials are commonly in use today. Glass Ionomer Cements are family of fluoride releasing materials which offers modifications in the form of Giomers, Resin Modified Glass Ionomer Cements and Compomers. This modified material has the advantage of improved mechanical properties, inherent adhesion to tooth structure and release of fluoride. They have multiple utilities in dentistry ranging from pits and fissure sealant to liners and bases to restorative and core build up material. The book will act as a guide for undergraduate and postgraduate students about RMGICs available to dentistry and about their interaction with sources of fluoride. It also covers the impact on hardness of material as a result of exposure to sources of fluoride over the period of time.

This book was released on 2011 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: In order to improve the clinical performance of RMGIC 3M ESPE and GC America introduced paste/paste resin-modified glass ionomer cements, Ketac [trademark symbol] Nano and Fuji Filling [trademark symbol] LC, respectively. Both companies developed non-rinse substrate conditioners (i.e., Ketac Nano Primer-3M ESPE and GC Self-Conditioner-GC America) that should be used with these new materials instead of the conventional polyacrylic acid. It has been also advised by both manufacturers to use this novel substrate conditioner with the previously marketed RMGICs. Objective: to investigate whether the use of novel non-rinse conditioners (i.e., Ketac Nano Primer 3M ESPE and GC Self Conditioner GC America) as substrate pre-treatment and the new paste/paste resin-modified glass-ionomer cement, RMGIC (Ketac [trademark symbol] Nano 3M ESPE and Fuji Filling [trademark symbol] LC GC America) would affect the microtensile dentin bond strength (æTBS) of the material when compared to the traditional RMGIC with polyacrylic acid as a surface substrate pre-treatment. Materials and Methods: 96 extracted non-restored human molar were sectioned to expose occlusal dentin. Dentin surface was finished with SiC paper to standardize the smear layer. Bonding protocols of the different materials to dentin were performed following the use of two dentin conditioners. Eight groups (n=12) were tested: G1: Ketac Nano Primer + Ketac Nano, G2: Ketac Conditioner + Ketac Nano, G3: Ketac Nano Primer + Photac Fil, G4: Ketac Conditioner + Photac Fil, G5: GC Self Conditioner + Fuji Filling LC, G6: GC Cavity Conditioner + Fuji Filling LC, G7: GC Self Conditioner + Fuji II LC and G8: GC Cavity Conditioner + Fuji II LC. The specimens were stored in 37°C for 24h in 100% humidity before cutting non-trimmed beams for the æTBS with cross-sectional areas of approximately 0.8 × 0.8 mm2. Nine beams were used from each specimen. Test was done using universal testing machine at a cross-head speed of 1mm/min. Debonded specimens were examined under a stereomicroscope at 45× magnification to evaluate the failure mode. Eight randomly chosen representative debonded beams were imaged under a scanning electron microscope (SEM). Results: æTBS in MPa (mean " SE) were: G1: 9.5"1.0, G2: 11.0"1.0, G3:20.0"1.0, G4:16.8"0.9, G5: 15.1"1.0, G6: pre-test failure, G7: 20.0"1.0, G8:14.1"0.9. Weibull-distribution survival analysis was used to compare the differences in microtensile peak stress among the groups. Group5 has cohesive predominant faultier mod while the other groups have adhesive predominant failure. Conclusion: Within the limitations of this study, the use of the novel non-rinse conditioners did not improve the microtensile bond strength of new paste/paste RMGIC to dentin. In fact, the use of the novel non-rinse conditioners enhanced the bond strength of the traditional RMGIC to dentin.
