Endodontic Access Through Zirconia Crowns: A Comparative Evaluation Of 3d Guided Versus Free-Handed Techniques, Maryam Alrughaib

Theses and Dissertations

Objective:

Accessing canals through full-coverage zirconia crowns is challenging and may increase the risk of misdirection, excessive dentin removal, and prolonged chair time. Guided endodontic access has been proposed to improve efficiency and precision. This study compared the accuracy and time efficiency of guided versus free-hand endodontic access through zirconia restorations. The hypothesis was that guided access would enhance canal localization precision and significantly reduce access time.

Methods:

Thirty-two extracted maxillary premolars were restored with 1-mm–reduced monolithic zirconia crowns (3Y-TZP, Katana HTML, Kuraray, Japan) and mounted in Modupro models. Teeth were assigned to two groups (n = 16 each): guided …

Lead X-Ray Vests: Pros And Cons In Dental Radiography And Patient Education On Radiographic Technology, Kayla D. Oakley, Emily Deker

Dental Hygiene Student Scholarship

Problem: There is a greater need to emphasize and educate patients and providers about radiologic advancements and patient exposure. The tradition of placing lead x-ray vests on patients for all radiographs is no longer a necessity. Without the explanation of why lead aprons are no longer needed, unnecessary steps for the provider and potential harm to the patient could be caused.

Methods: This review of literature was assembled by analyzing data from primary and secondary sources through online databases. The most recent research on the risks and benefits of the use of lead x-ray vests towards patients in …

Consideration For Care For Your Patient With Cerebral Palsy, Katlin R. Cannon, Melissa Stowe, Brooke Ryan

Dental Hygiene Student Scholarship

Cerebral palsy (CP) is a common developmental neurological disorder affecting about 2-3 children out of 1,000. CP is the result of infant brain damage or abnormal development resulting in impaired muscle control, coordination, tone, reflex, posture, and balance. These patients are unable to control motor movements of their muscles of mastication and facial expression, causing excessive drooling, clenching, bruxism, and other oral health-related issues. This lack of motor control affects their ability to swallow and often limits these patients to a liquid diet. This can lead to vitamin deficiencies and result in further developmental problems. As an example, a deficiency …

Collaborative Instruction For Information Retrieval And Appraisal Skills In Evidence-Based Practice Models For Dental Hygiene Students., Irene M. Lubker, Joan M. Pellegrini

VCU Libraries Faculty and Staff Presentations

Objectives:

1. Collaborate with VCU Dental Hygiene Program faculty to develop and evaluate a model of evidence-based practice (EBP) for students in didactic and clinical settings.

2. Describe how a course was modified to emphasize evidence-based practice.

3. Analyze course evaluations and student scholarly output.

Methods/Materials:

Dental educators strive to develop graduates who practice evidence-based practice and whose clinical decisions are based on current scientific research. A medical librarian was invited to assist in integrating EBP into the dentistry curriculum in 2012. To gain a better understanding of EBP in dental settings, the librarian and dental hygiene faculty attended the …

Restoring Lateral Incisors And Orthodontic Treatment: Perceptions Among General Dentists And Othodontists, Matthew A. Sandretti, Bhavna Shroff, Steven J. Lindauer, Al M. Best

Theses and Dissertations

The purpose of this study was to identify and compare preferences and perceptions of orthodontists and general dentists when restoring peg-shaped lateral incisors. The investigation sought to summarize these preferences with regard to treatment planning, tooth preparation and interdisciplinary communication. A pair of mailed and electronic surveys was distributed to 1,500 general dentists and orthodontists, respectively. The results indicated that general dentists perceived that general dentists held the primary decision-making responsibility, while orthodontists disagreed (P<0.0001). Orthodontists prioritized the treatment goals of Class I canine relationship and overbite/overjet more significantly than general dentists, whom valued tooth proportions more highly (P<0.0001). General dentists reported receiving significantly less input than orthodontists report seeking (P<0.0001).The consensus of both groups showed that the tooth should be positioned centered mesiodistally and guided by the gingival margins incisogingivally. Both groups agree that orthodontists must improve communication to improve treatment results.
