Dental Hygiene Students' Matching Accuracy When Comparing Antemortem Dental Radiographs And Oral Photographs To Simulated Postmortem Winid3® Odontograms, Brenda T. Bradshaw, Amber W. Hunt, Emily Ludwig, Tara L. Newcomb

Dental Hygiene Faculty Publications

Matching dental antemortem (AM) and postmortem (PM) data for human identification is especially challenging when the workforce is limited. Dental hygienists have served mass fatality incidents (MFIs) due to dental-related expertise. However, forensics within dental hygiene education and research on transferable skills is limited. This qualitative balance design study assessed senior dental hygiene students' match accuracy of simulated cases varying in dental identifiers based on AM full mouth series (FMS) radiographs and oral photographs to PM WinID3® odontograms to demonstrate possible disaster victim identification (DVI) transferable skills gained during formal education. A convenience sample of senior dental hygiene students ( …

A Flash Of Inspiration: Enhancing Dental Student Drug Recognition, Benjamin D. Zeitlin

All Dugoni School of Dentistry Faculty Articles

Students preparing for exams often retain the complexities of a subject but instant recognition and recall is something that, for most, takes time and consistent, repeated study to establish. This can happen through well-managed spaced learning (iterative study) prior to examination; given the preponderance of massed study (cramming for a subject),1 however, many students require long-term exposure in the clinic to patients’ medical histories to achieve instant recall. Understanding the applied pharmacology of common drugs is a current American Dental Association accreditation standard. Ideally, dental students should demonstrate a consistent level of basic drug recognition and the ability to retrieve …

Effect Of Low-Level Laser On Miniscrew Displacement During Canine Retraction: A Randomized Controlled Clinical Trial, Aly Osman, Nadia El Harouni, Mohamed Shokry

International Arab Journal of Dentistry

Background: Anchorage is an important consideration for successful orthodontic treatment. Skeletal anchorage by miniscrews provided better anchorage control then the ordinary extra-oral and intra-oral appliances. However, the stability of the miniscrews is still questionable since they might move under orthodontic loading.

Objectives: The aim of this study was to evaluate the effect of Low Level Laser on the miniscrew displacement when subjected to orthodontic force during canine retraction using CBCT.

Methods: Twelve patients who required bilateral extraction of upper first premolar and absolute anchorage were recruited from the outpatient clinics of the Department of Orthodontics, Faculty of …

The Effect Of Bevel On Fracture Resistance Of Gic Restorations In Primary Molars: An In Vitro Study, Audrey Fikani, Lara Nasr, Elie Khoury, Marianne Freiha, Marc Krikor Kaloustian, Feriale Abi Zeid Daou, Melissa Chaaya, Marlene Khoury

International Arab Journal of Dentistry

Introduction: Glass ionomer cements (GICs) are commonly used for restorations in primary molars due to their adhesive, hydrophilic, and bioactive properties. However, their low mechanical resistance may limit their use in proximal cavities. Recent advancements in GICs, such as the high viscosity GIC EQUIA Forte®, have improved their mechanical properties. The effect of a Cavo superficial bevel on the mechanical strength of GIC restorations has been previously studied.

Objectives: To investigate the effect of a Cavo superficial bevel on fracture resistance and the type of fracture (adhesive, cohesive, or catastrophic) in EQUIA Forte® GIC restorations in primary molars. …

International Arab Journal of Dentistry

Introduction: The purpose of this in vitro study was to test the influence of the margin design of implant supported monolithic zirconia crowns and test if monolithic zirconia crowns with extra fine finish line thickness cemented on zirconia implant abutments can bare the maximum masticatory forces on molars and hence be used in the posterior region.

Methods: Fourteen identical monolithic zirconia crowns cemented on zirconia implant abutments mounted on titanium bases and fixed on implant replicas embedded in PMMA resin were divided into two groups: group I designed with a 0.5 mm CFL (CFL) and group II with …

Assessment Of Mandibular Cortical Bone Thickness For Miniscrew Placement In Relation To The Vertical Facial Patterns Using Cbct: A Cross-Sectional Study, Rima Daoui, Aly Osman

International Arab Journal of Dentistry

Introduction: The need of more anchorage in the orthodontic daily practice has introduced the use of temporary anchorage devices (TADs). Cortical bone thickness has been one of the major factors on the success rate of the stability of TADs. Different vertical dimension patterns can be found among orthodontic patients with potentially variable cortical bone thickness.

Aim of the study: to assess the cortical bone thickness in the posterior region of the mandible in relation to different vertical facial patterns using Cone-beam computed tomography (CBCT) and to evaluate the progressive change in the thickness of cortical bone from 4,6 …

International Arab Journal of Dentistry

Introduction: Marginal bone loss after implant placement is one of the most used criteria to assess the success of osseointegrated implants over time. The type of implant connection and implant surface type are reported to have an influence on bone remodeling around the placed implants. This study aimed to evaluate marginal bone loss around two implant systems with different connections and surfaces in horizontally augmented sites.

Methods: This randomized control pilot study included 8 implants placed in 3 patients who needed implant placement in previously horizontally grafted sites. The placed implants were divided into two groups: group 1 …

Is Cutaneous Profile Perception An Indicator Of Skeletal Class Iii Malformation Treatment Plan? A Cross-Sectional Study, Ibrahim Hatoum, Rania Nassar

International Arab Journal of Dentistry

Background: The treatment choice in adults with skeletal class III malocclusion represents a challenging task for orthodontists, especially in borderline cases. With the growth spurt being surpassed, the clinician is left between two treatment options: orthodontic camouflage or orthognathic surgery. Around the years, many studies tried to uncover a guide model which enables practitioners to distinguish between skeletal class III that can be appropriately treated by orthodontics alone and those needing surgical intervention.

Aim: The aim of this study is to demonstrate the importance of cutaneous profile perception as a subjective decisive parameter in the treatment of borderline …

Calcifying Odontogenic Cyst – A Three-Dimensional Radiological Evaluation By Cone Beam Computed Tomography, Karthik Rajaram Mohan, Saramma Mathew Fenn, Ramachandra Reddy Venkatesha

International Arab Journal of Dentistry

Calcifying odontogenic cysts is an odontogenic cyst that gives rise to painless swelling which expand and occasionally perforate bone. Most of them are between 2 to 4 cm in diameter. Approximately 75% occur in anterior canine-incisor region. The highest incidence of occurrence is between 10 and 29 years. Radiographically they appear as well-circumscribed, unilocular cystlike areas with scattered radiopacities which range from mere flecks to large masses. The related tooth usually gets displaced. Radiopaque flecks occur in radiographic features of some lesions which undergo osteolysis during their development. They occur as a result of dystrophic calcifications in long standing chronic …

Rehabilitation Of A Patient With Single Complete Tooth-Supported Overdenture Against The Unmodified Natural Dentition Using Functionally Generated Path Technique: A Case Report, Akanksha Shinde, Nilesh Bulbule, Varun Bhatt, Gayathri Balachandran, Amit Jagtap

International Arab Journal of Dentistry

Meyer’s proposed chew-in technique also called functionally generated path (FGP) technique, is indicated for the restoration of an edentulous arch that is opposed by natural teeth as it does seem to provide the most accurate method of recording occlusal patterns, also help to minimize the effects of negative factors, and to overcome the deficiencies of articulators. As stated by Rudd and Morrow, this technique is especially suitable for tooth-supported complete dentures, due to inherent stability of tooth-supported record bases helps in recording jaw relationships accurately. Whenever a single complete denture is opposed by natural dentition, problems observed are abrasion of …
