Anatomical Study Of The Greater Palatine Artery: Clinical Implications For Palatal Graft Procedures, Nina Marie Karin Cunningham

Student Theses, Dissertations and Capstones

Introduction: The palate is a well-established donor site for obtaining graft tissue in periodontal plastic surgery procedures. However, proximity to the adjacent teeth on the lateral aspect and the greater palatine neurovascular bundle (GPB) on the medial aspect limit the amount of graft tissue that can be obtained from the palate. Previous studies have been concerned with the location of the greater palatine foramen as well as the greater palatine artery (GPA) and have established guidelines on how to estimate the distance between the teeth and the GPB. Traditionally, clinicians follow these guidelines and choose to avoid removing graft tissue …

Current Status Of Direct Pulp-Capping Materials For Permanent Teeth, Takashi Komabayashi, Qiang Zhu, Robert Eberhart, Yohji Imai

Dental Medicine Faculty Publications

Direct pulp-capping is a method for treating exposed vital pulp with dental material to facilitate the formation of reparative dentin and to maintain vital pulp. Two types of pulp-capping materials, calcium hydroxide and mineral trioxide aggregate, have been most commonly used in clinics, and an adhesive resin has been considered a promising capping material. However, until now, there has been no comprehensive review of these materials. Therefore, in this paper, the composition, working mechanisms and clinical outcome of these types of pulp-capping materials are reviewed.

A Comparative Evaluation Of Endodontic Irrigation Methods For Removal Of The Smear Layer, Ramzi Walid Alhashimi

Student Theses, Dissertations and Capstones

The purpose of this in vitro study is to compare the effect of various irrigation systems on smear layer removal in curved root canals. Root canal irrigation plays an important role in the debridement and disinfection of the root canal system. It has been well documented that the flushing component of the irrigants is as important as the tissue dissolving capability. Therefore, the efficacy of the irrigant might also be influenced by the method by which it is introduced. Fifty-one recently extracted molar teeth with root curvatures of more than 30° were selected according to Schneider's method. The teeth were …

Comparison Of Resistance To Sliding Between Brackets And Archwires Utilizing Various Ligature Materials, Jagdesh Dudani

Student Theses, Dissertations and Capstones

Objectives: The purpose of this study was to investigate the association between ligature material and frictional force created during orthodontic cuspid retraction. Maximum static and mean kinetic frictional resistance between conventional metallic orthodontic appliances and esthetic orthodontic appliances will be compared as well. Background: The use of ceramic brackets in conjunction with coated archwires and ligatures as an alternative to conventional stainless steel appliances has increased in response to the demand for more esthetic orthodontic appliances. Esthetic appliances are associated with increased frictional forces and therefore thought to slow the orthodontic treatment. Knowledge of frictional forces generated within various orthodontic …

Accuracy And Consistency Of Preformed Orthodontic Arch Wires And The Effect Of Energy Drinks, Caroline Albea

Student Theses, Dissertations and Capstones

Introduction: Selection of the proper arch wire requires a thorough knowledge and understanding of the mechanical properties of wires as well as the system being used. Even with careful selection, orthodontists may experience different results due to the inaccuracy of the stated wire dimensions. Previous studies by Melling et al. have shown nickel titanium, stainless steel, and chrome-cobalt arch wires to be thinner than their marketed values.1 However, the literature is lacking information regarding (1) accuracy of the currently available orthodontic arch wires and (2) the consistency of the arch wire size. Orthodontic wires are also exposed to various chemical …
