The Visual And Spectrophotometric Effect Of External Bleaching On Omnichroma Resin Composite And Natural Teeth, Michael Brian Evans

Graduate Theses, Dissertations, and Problem Reports (ETD)

Objective: To determine the visual and spectrophotometric effect external tooth bleaching has on natural tooth structure and OMNiCHROMA composite at various number of treatments. Variables were compared to determine if there is a detectable difference between the composite and the tooth before and after bleaching.

Methods: Preparation and restoration of 25 previously extracted teeth was completed. OMNiCHROMA composite was used. Each tooth was measured visually with a VITA shade guide and a colorimeter. Measurements were recorded before bleaching, after 5 and 10 treatments. Statistical analysis was completed and ΔE values between the composite and tooth were compared between the 3 …

The Influence Of Fatigue Load To Various Adhesive Resin Luting Agents In A Zirconia-Reinforced Lithium Silicate Ceramic Bonded To Dentin, Ratikorn Watananiyom

Chulalongkorn University Theses and Dissertations (Chula ETD)

Purpose. To examine fatigue failure load value of etch-and-rinse and self-adhesive luting systems used to bond ZLS to dentin. Moreover, this study seeks to evaluate whether the application of unfilled resin on silanated ceramic intaglio surface could improve fatigue failure load value. Methods. Vita Suprinity (VS, Vita Zahnfabrik) blocks were sectioned into cylindrical shape (5 mm in diameter and 1.5 mm in height). All VS were crystallized, and bonded surfaces were treated as followed: Heliobond (HB, Ivoclar Vivadent) application after silanization and non-application of HB. Each VS was cemented to each flat occlusal dentin surface of extracted human molar, following …

Chulalongkorn University Theses and Dissertations (Chula ETD)

This clinical study aims to determine differences in lipstick stains between ceramic veneers and natural teeth. Types of lipsticks affected lipstick stains on ceramic veneers and natural teeth were also investigated. A total of 30 patients were divided into two groups: ceramic-veneer (CV) group and natural-teeth (NT) group with 15 patients in each group. Seven lipstick types: Gloss & Balm, Gloss & Sheer, Cream, Liquid matte, Matte & Frost, Satin, and Matte were applied on patients’ lips. Six labial surfaces of maxillary anterior teeth were evaluated for the frequency of lipstick staining with each type of lipstick. Thus, 90 maxillary …

Exploring The Use Of Pulsed Erbium Lasers To Retrieve A Zirconia Crown From A Zirconia Implant Abutment, Ahmed Elkharashi

Theses and Dissertations

Removal of zirconia crowns, commonly used as cement-retained implant fixed restorations, can be challenging. Conventional methods of crown removal are time consuming and often leave irreparable damage to the crown, which can be costly to patients and practitioners. This research explored the use of two different types of pulsed erbium lasers, erbium-doped yttrium aluminum garnet laser (Er:YAG) and erbium, chromium-doped yttrium, scandium, gallium and garnet (Er,Cr:YSGG), as non-invasive tools to retrieve cemented zirconia crowns from zirconia implant abutments. Times needed to remove the crowns were recorded and analyzed using ANOVA (��=0.05). No statistical differences between the debond times of each …

Comparison Of External Root Resorption In Orthodontic Treatment Between Self-Ligating And Conventional Bracket Systems, Nuriah Bohari, Noor Airin Koah, Rohana Ahmad

Journal of Dentistry Indonesia

The relationship between orthodontic bracket systems and external root resorption has remained debatable. Objective: This study compared the magnitude and pattern of the external root resorption of maxillary incisors as induced by self-ligating and conventional bracket systems via cone beam computed tomography and medical imaging programs. Methods: Eight participants were recruited for each bracket system. Their maxillary incisors were scanned at the beginning (T0) and 18 months into treatment (T1). Three-dimensional models of the four maxillary incisors at T0 and T1 were reconstructed using the Mimics program. The difference in root length between T0 and T1 models represented external root …

The Effectiveness Of Resin-Modified Glass Ionomer Varnish In Preventing White Spot Lesions During Fixed Appliance Orthodontic Therapy: An In Vitro Study, Bradley Herman

Theses & Dissertations

The purpose of this investigation was to evaluate the efficacy of a glass ionomer varnish in preventing demineralization of enamel adjacent to and some distance away from an orthodontic bracket. Forty extracted human molars were divided into four different treatment groups (varnish in distilled water, varnish in acetic acid, enamel in acetic acid, and enamel in distilled water). Two 3 x 3 mm graphite windows were drawn on the tooth, one adjacent to the bracket and one 3 mm away from the first window, indicating the scanning area. Varnish was applied to the teeth in the varnish groups and all …

Part I: Comparative Analysis Between Natural And Ceramic Teeth, Aneeza Hussain, Ibeth Erazo

Publications and Research

Ceramics play a fundamental role in Dentistry and are used widely, due to their ability to mimic the optical characteristics of enamel and dentine, as well as for their biocompatibility and strength. Initially, dental ceramics were materials that formed part of systems, designed with the purpose of producing dental prosthetics that in turn were used to replace missing or damaged dental structures. However, due to the increased demand for esthetics, its development has gone beyond in such a way that it has led to the development of all ceramic restorations. So that, in the last few decades, there have been …

Marginal Staining Between Pressed Lithium Disilicate Ceramic Crowns And Direct Restorative Materials By Various Fluids : A Microleakage Study., Sarah Ann Jestel

Electronic Theses and Dissertations

When treating patients with existing restorations in which indirect restoration placement is indicated and crown lengthening surgery is contraindicated, dentists may choose to finish the crown margin on an existing restoration. The interface between the two dental restorations (resin composite and ceramic crown) may be more susceptible to microleakage and fluid staining, reducing restoration longevity. In this study, 80 extracted molars received indirect restoration margins finished on different direct restorative materials (resin-modified glass ionomer and conventional, flowable, and bulk fill nano-hybrid resin composite) and subjected to common staining fluids of coffee, tea, red wine, or Coca-Cola. If the clinician must …

To Repair Or Replace: That Is The Restorative Question, Juhstin M. Brown, Clement S. Augustus

Dental Hygiene Student Scholarship

Objective/Aims: During dental visits, patients spend the majority of their time with their dental hygienist. At these recall appointments the patient’s face-to-face time with the dentist may be short. At this part of the appointment the dentist may diagnose the need for restorative treatment for the patient. Part of the hygienist’s responsibility is to explain treatment options for teeth with restorative needs. The purpose of this review of literature is to provide both options for restoration of dentition to a functional/aesthetic state.

Methods: Studies pertaining to the topic were searched using PubMed database. Keywords used in the search were amalgam, …
