Characterization of the Organic Matrix of Mature Human Tooth Enamel: Structure, Macromolecular Composition and Effect of Radiotherapy
(2014-09-30)Mature human tooth enamel contains a small amount of organic matrix locally concentrated within its innermost region, which is tougher and more crack resistant than the outer bulk phase. Although the enamel organic matrix ... -
Clinical Acceptability of Digital Indirect Bonding Compared to Direct Bonding by Varying Orthodontic Experience: Pilot Study
(2023)This pilot study was a two-factor, in-vitro pilot study comparing the clinical acceptability of orthodontic bracket placement between digital indirect and direct bonding techniques and between participants with three levels ... -
Coated and Uncoated Nickel-Titanium Archwires: Mechanical Property and Surface Topography Response to a Simulated Oral Environment with and without Bracket-Related Load Deflection Induced Stress
(University of Missouri--Kansas City, 2017)This study examined the effect of exposure to bracket-related load deflection on the mechanical properties and surface characteristics of esthetic coated and uncoated nickel titanium archwires. Two types of coated ... -
Dental Students' Knowledge Related to Peri-Implantitis Diagnosis and Willingness to Treat or Refer: A Pilot Study
(2024)This pilot study examined whether demographic factors affect student knowledge, ability to diagnose, and willingness to refer biological implant complications, specifically peri-implant mucositis and peri-implantitis. This ... -
Digital Technology and Digital Workflow Application in the Current Landscape of Private Practice Orthodontics
(2021)This study examined which demographic factors and practice characteristics influence orthodontists to utilize a digital workflow in their private practice, as well as which factors influence their opinions on the current ... -
Effect of Build Angle and Model Body Type (Solid vs Shell) on Accuracy of 3D-Printed Orthodontic Models Using a DLP Printer
(2022)This study examined the effect that print angulation and model body type (solid vs. shell) have on the accuracy of orthodontic models printed with a digital light processing (DLP) 3D printer. The following six configuration ... -
Effect of Delayed Polymerization Time and Bracket Manipulation on Orthodontic Bracket Bonding
(2014)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 ... -
Effect of Final Irrigation on Sealer-Dentin Interface for a Methacrylate-Based Resin Sealer
(2015)The purpose of this study was to evaluate the effect of different final irrigation technique (removing or not removing demineralized collagen) in combination with controlled intracanal residual moisture level (dry or ... -
Effect of Highly Filled Light-Cured Resin Sealant on Bracket Shear Bond Strength in Demineralization Conditions
(University of Missouri -- Kansas City, 2018)This study examined the effect of a highly filled light-cured sealant (HFLCS) on bracket shear bond strength and subsequent adhesive remnant index (ARI) following exposure to cariogenic challenge. Specimens were divided ... -
Effect of Radiotherapy on Nano-Mechanical Properties and Chemical Composition of Tooth Enamel and Dentin
(2015)The purpose of this study was to understand radiotherapy-induced dental lesions characterized by enamel delamination near the dentin-enamel junction (DEJ) by evaluating enamel and dentin nano-mechanical properties and ... -
The Effect of Resection on the Sealer-Dentin Interface in Roots Obturated with Tricalcium Silicate Sealer: A Confocal Laser Scanning Microscopy and India Ink Penetration In Vitro Pilot Study
(University of Missouri -- Kansas City, 2018)Anatomical considerations may limit access to teeth for root-end preparation and root-end filling. Having the canal pretreated and filled with a calcium silicate based filling material, apical surgery can be limited ... -
The Effect of Topical Fluoride Agents on Coated Nickel-Titanium Archwires
(2015)This study examined the effect of exposure to topical fluoride agents on the mechanical properties and surface characteristics of esthetic coated nickel-titanium archwires. Two types of coated wires were tested: one with ... -
Effects of Alpha-Tocopherol Antioxidant on the Bonding Properties of Resin Adhesive to Dentin Bleached with Sodium Perborate
(University of Missouri--Kansas City, 2017)Previous reports have shown diminished capacity for bonding after bleaching teeth. Reversal of the bond strengths back to pre-bleached levels can be obtained with application of 10% alpha-tocopherol in a 2-hour time ... -
Effects Of Delayed Polymerization Time and Bracket Manipulation on Orthodontic Resin Modified Glass Ionomer Adhesive
(2015)This study examined the effect of varying delayed polymerization times in combination with bracket manipulation on shear bond strength (SBS), degree of conversion (DC), and adhesive remnant index (ARI) score when using a ... -
Effects of fluoride varnish application and phosphate buffered saline solution with or without demineralizing conditions prior to bracket bonding on subsequent enamel-bracket shear bond strength
