Endodontic Microsurgery Using Dynamic Navigation And Trephine Burs, Trenton Smith, Sameer Jain, Jeffery Nick Sanders, Michael Block, Mark Odom, Albert F. Mcmullen

School of Dentistry Faculty Publications

Objectives: The use of the surgical operating microscope, CBCT imagining, biocompatible filling materials and ultrasonic instruments have improved the success and predictability of apical surgery. Despite these advances, more accurate and precise techniques for creating osteotomies and root-resections (apicoectomies) have not been widely adopted. This study highlights how dynamic navigation systems (DNS) can help avoid unnecessary dentin removal and “mitigate iatrogenic errors” such as root perforation. Methods: A total of 56 root-end resections were planned and completed on two sets of identical TrueJaw Endosurg models (DE Labs, Santa Barbra, CA, USA). One set of maxillary and mandibular jaws were used …

Stratasys Printed 3-D Mandibular Molar With Tooth Anatomy And Texture, M. Austin White, Charles E. Taylor, Edwin Kee, Albert F. Mcmullen

School of Dentistry Faculty Publications

Introduction: We used CBCT scans of a human mandibular molar in concert with the Stratasys 3-D printer to fabricate said teeth with similar texture and hardness to enamel, dentin, and cementum. The printed tooth should also have the same crown and root anatomy, as well as root canal anatomy of the scanned tooth. Methods: One mandibular first molar was scanned (Carestream Dental CS 9600 CBCT) and printed (Stratasys 3D multi-material printer). A (Micromet 5104) hardness tester was used to test the hardness of the printed tooth. Nine combinations of two different materials (Stratasys’ Vero Pure White and Agilus 30 Clear …

Uses Of Herbal Extracts In Endodontology: A Literature Review, Reem Chamseddine, Roula S. Abiad

BAU Journal - Science and Technology

The use of natural herbal extracts in the field of dentistry, and specifically in endodontology had gained a high popularity in the past few years. The main objective of endodontic treatment is to prevent and eliminate the infection from the root canal, seize the invasion of microorganisms to periradicular tissues and preserve the natural dentition. Studies had shown that some herbs are better alternatives to traditional chemical irrigants or medicaments used in root canal treatment, based on their potential antimicrobial effect, smear layer removal capabilities, tissue dissolution effect, antioxidant, anti-inflammatory and regenerative properties. Aim: The purpose of this literature review …

Cryotherapy In The Field Of Endodontics: A Literature Review, Amena Al Bast, Roula S. Abiad

BAU Journal - Science and Technology

Cryotherapy is a recent approach in the field of endodontics. It is a remedy that subject tissue to low temperature. Low temperature induces vasoconstriction limiting inflammation, pain and edema and analgesia by reducing the nerve conduction velocity. The aim of this review is to point out the different and recent clinical applications of cryotherapy in the field of endodontics and to describe its physiology and its effect regarding postoperative pain and inflammation. A literature search from PubMed, Scopus, ScienceDirect and EBSCO databases and other resources using specific keywords results in articles to determine the effect of applying cryotherapy in the …

Managing Perforating Internal Root Resorption Non-Surgically: A Report Of 2 Cases And A Review Of The Literature, Joseph C. Stern Dds

The New York State Dental Journal

Aim: To describe the use of bioceramics in the non-surgical treatment of perforating internal root resorption.

Summary: Confusion over the subject of root resorption seems ubiquitous in the general dental community. Because of the several subheadings such as internal, external cervical, and apical, and because of a variety of causes for each, such as trauma, pressure, infection, inflammation, and systemic, the confusion can be understandable. It seems that this confusion arises primarily from the nomenclature describing the location and etiology of root resorption. This case report deals with perforating internal root resorption (IRR), its causes, diagnosis, and successful nonsurgical treatment, …

Would Access Cavity Design Affect The Mechanical Behaviour Of Tooth: A Finite Element Study, Muhammad Ashraf Elhusseini, Engy Kataia, Hala Khalil

International Arab Journal of Dentistry

Two distinct access cavity designs were used to access Two simulated finite element models (FE). (Lingual (LAC) and incisal (IAC)). Three experimental FE models, including the IT model, were developed: LAC and IAC. For every simulated model, one distinct radicular preparations was carried out of size #30/.04. The incisal edge was subjected to an occlusal cycle load of 120 N. The maximum von mises stresses (VMS), maximum principal stresses (MPS), and stress distribution patterns were assessed and calculated quantitatively. It was concluded that the mandibular incisor's biomechanical behavior is significantly influenced by the size of the access design. Biomechanically the …

Effect Of Taper And Pitch On Nickle-Titanium File With Variable Cross Section To Its Cyclic Fatigue (In Silico Study), Yustika Chrysandra, Tunjung Nugraheni, Wignyo Hadriyanto

Journal of Dentistry Indonesia

The geometric design of an endodontic file includes cross-sectional shape, taper, and pitch. NiTi endodontic files of OneCurve (MicroMega) are made of two variations of cross-sectional shape, that is, double-s shaped and triple helix. Various kinds of modifications were made to increase the resistance of the NiTi endodontic files from fracture. Cyclic fatigue is the most common factor that causes a fracture of the endodontic file. Objective: The purpose of this study was to obtain a NiTi endodontic file design that has the best cyclic resistance value based on its taper size and number of pitch. Methods: This …
