Book excerpt: The objective of this study was to determine the efficiency of an argon laser in polymerizing a light cure orthodontic adhesive. Metal brackets were bonded to 37 buccal and 148 lingual surfaces of 185 premolars. Five groups of 37 premolars were cured as follows: Light 40 seconds buccal, light 40 seconds lingual, laser 5 seconds lingual, laser 10 seconds lingual and laser 15 seconds lingual. All bonded specimens were placed in distilled water for 30 days at 37$\sp\circ$C and thermal cycled for 24 hours. The brackets were detached using a shear load on an Instron machine and the site of bond failure was examined under 10X magnification.

This book was released on 2015-08-06 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: With every passing day, demand of esthetic restoration is gaining momentum; which has made esthetic materials like composite resin the restorative material of choice. Methods and devices to cure composite resin have evolved jointly; passing from chemically cured resins to modern form of light cured composite resins. Success and predictability of composite resin restorations depends on one major factor i.e. degree of resin polymerization achieved during its placement in the prepared cavity.The ability of light curing units to deliver enough light at appropriate absorption spectrum is crucial to optimize the physical properties of composite resin. Inadequate polymerization has been associated with inferior properties and failure of restoration.

Book Synopsis The Effect of a Novel Photoinitiator System (RAP) on Dental Resin Composite's Flexural Strength, Polymerization Stress, and Degree of Conversion by : Kellie M. Schaub
Download or read book The Effect of a Novel Photoinitiator System (RAP) on Dental Resin Composite's Flexural Strength, Polymerization Stress, and Degree of Conversion written by Kellie M. Schaub and published by . This book was released on 2009 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objectives: A new technology has been introduced into the field of dental resin composites that professes to enhance light-curing efficiency. Rapid amplified photopolymerization (RAP) initiator technology has not yet been fully compared with resin composites with conventional initiators such as camphorquinone (CQ). The purpose of this study was to compare and contrast the effects of this novel technology (RAP) on properties of two light-cured resin composites. Flowable (EFQ) and microfilled (ESQ) experimental composites were fabricated and supplied from Tokuyama Dental with (w/RAP) and without RAP (w/o RAP). The flexural strength (MPa) and flexural modulus (MPa) were obtained using a three-point bending apparatus (Sintech Renew 1123, Instron Engineering Corp., Canton, MA). Polymerization stress curves were created using a tensometer (American Dental Association Health Foundation, NIST, Gaithersburg, MD) which were then used to calculate the maximum stress rate. Finally, the degree of conversion was measured using infrared spectroscopy (Jassco FT-IR spectrometer, Model: 4100, Jasco Corporation, Tokyo, Japan). When evaluating the flexural strength, the peak stress for EFQ w/RAP was significantly higher than EFQ w/o RAP (p = 0.0001). This was statistically not significant for the ESQ group, even though ESQ w/RAP did have a higher peak stress then ESQ w/o RAP (p = 0.28). The interaction between resin type and RAP was not significant when evaluating the flexural modulus (p = 0.21). Formulations with RAP had a significantly higher flexural modulus then w/o RAP (p = 0.0001). Experimental resins with RAP had significantly higher maximum stress rates than those w/o RAP when evaluating polymerization stress (p = 0.0001). Finally, groups w/ RAP appeared to have a higher degree of conversion than groups without (p = 0.0057). This study showed that the experimental composites with RAP had greater mechanical properties than those without. Unfortunately, the increase in polymerization stress causes concern clinically due to the chance of leakage at the restoration/tooth interface. One of the main potential disadvantages of this new RAP technology is an increase in the polymerization stress. Deciding if this amount of polymerization stress is clinically acceptable is yet to be accomplished.

Book Synopsis Effect of Delayed Polymerization Time and Bracket Manipulation on Orthodontic Bracket Bonding by : Michael J. Ponikvar
Download or read book Effect of Delayed Polymerization Time and Bracket Manipulation on Orthodontic Bracket Bonding written by Michael J. Ponikvar and published by . This book was released on 2014 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examined the effect of bracket manipulation in combination with delayed polymerization times on orthodontic bracket shear bond strength and degree of resin composite conversion. Orthodontics brackets were bonded to extracted third molars in a simulated oral environment after a set period of delayed polymerization time and bracket manipulation. After curing the bracket adhesive, each bracket underwent shear bond strength testing followed by micro-Raman spectroscopy analysis to measure the degree of conversion of the resin composite. Results demonstrated the shear bond strength and the degree of conversion of ceramic brackets did not vary over time. However, with stainless steel brackets there was a significant effect (p ≤ 0.05) of delay time on shear bond strength between the 0.5 min and 10 min bracket groups. In addition, stainless steel brackets showed significant differences related to degree of conversion over time between the 0.5 min and 5 min groups, in addition to the 0.5 min and 10 min groups. This investigation suggests that delaying bracket adhesive polymerization up to a period of 10 min then adjusting the orthodontic bracket may increase both shear bond strength and degree of conversion of stainless steel brackets while having no effect on ceramic brackets.
