The Impact of Technology Teaching in the Dental Predoctoral Curriculum on Students' Perception of Digital Dentistry.

The goal was to assess dental students' perception of digital technologies after participating in a CAD/CAM exercise for scanning, designing, and manufacturing computer-aided provisional fixed dental restorations. A survey was conducted among second- (pre-D2 and post-D2), first- (D1, negative control), third-, and fourth-year dental students (D3 and D4, positive controls). Only OSU College of Dentistry students who completed the activity and completed the surveys were included.

Recommendations for remaining agile in the face of a dental faculty workforce shortage.

Purpose: Dental education is facing a faculty workforce shortage. Lack of preparation risks faculty, student, and staff morale and is an impediment to institutional growth and innovation. Administrators and faculty must consider strategies to better prepare for, and be successful within, a faculty shortage environment.

Preventing or controlling periodontitis reduces the occurrence of osteonecrosis of the jaw (ONJ) in rice rats (Oryzomys palustris).

Introduction: Osteonecrosis of the jaw (ONJ) is an adverse event that requires association of both systemic risk factors, such as powerful anti-resorptives (pARs; e.g. zoledronic acid [ZOL]), and local oral risk factors (e.

Comparing the trueness of seven intraoral scanners and a physical impression on dentate human maxilla by a novel method.

Backgrounds: Intraoral scanner (IOS) accuracy is commonly evaluated using full-arch surface comparison, which fails to take into consideration the starting position of the scanning (scan origin). Previously a novel method was developed, which takes into account the scan origin and calculates the deviation of predefined identical points between references and test models. This method may reveal the error caused by stitching individual images during intraoral scan.

Knowledge and beliefs regarding temporomandibular disorders among orthodontists.

Introduction: This project was undertaken to accomplish 2 objectives: (1) to identify whether there is a discrepancy between orthodontists and experts in temporomandibular disorders (TMD) related to diagnosis and treatment of TMD patients, and (2) to influence the manner in which TMD curricula are taught in orthodontic residency programs, better preparing future orthodontic specialists to diagnose and treat (and refer) patients with TMD.

Methods: A survey invitation was e-mailed to 8870 members of the American Association of Orthodontists. Items were answered on a 6-point scale (0 = I don't know; 1 = strongly disagree; 2 = disagree; 3 = neutral; 4 = agree; 5 = strongly agree).

Evaluation of the trueness and precision of complete arch digital impressions on a human maxilla using seven different intraoral digital impression systems and a laboratory scanner.

Objectives: An impression accuracy study using a cadaver maxilla was performed using both prepared and intact teeth as well as palatal tissue.

Materials And Methods: Three crown preparations were performed on a cadaver maxilla. Seven different digital impression systems along with polyvinylsiloxane impressions were used to create digital models of the maxilla.

Evaluation of removable partial denture frameworks fabricated using 3 different techniques.

Statement Of Problem: Rapid advancements in computer-aided design and computer-aided manufacturing (CAD-CAM) have opened new pathways in the fabrication of removable partial dentures (RPDs) through additive and subtractive processes. Questions remain whether the digital pathway is an acceptable one compared with conventional analog or combined analog and digital pathways.

Purpose: The purpose of this clinical study was to determine the quality of RPD frameworks fabricated using 3 different fabrication methods: analog, combined analog-digital, and digital.

Antibiotic Perturbation of Gut Microbiota Dysregulates Osteoimmune Cross Talk in Postpubertal Skeletal Development.

Commensal gut microbiota-host immune responses are experimentally delineated via gnotobiotic animal models or alternatively by antibiotic perturbation of gut microbiota. Osteoimmunology investigations in germ-free mice, revealing that gut microbiota immunomodulatory actions critically regulate physiologic skeletal development, highlight that antibiotic perturbation of gut microbiota may dysregulate normal osteoimmunological processes. We investigated the impact of antibiotic disruption of gut microbiota on osteoimmune response effects in postpubertal skeletal development.

Analyzing Dental Students' Clinic Production Using Time-Based Relative Value Units: Ten-Year Cross-Cohort Mapping.

The analysis of dental students' clinical production/participation has been used to assess whether a prospective graduate is capable of unsupervised and independent practice (that is, competent to perform that practice). This method and others have inherent biases that may not accurately reflect whether the student has mastered the associated concepts and techniques required for dentistry. The aim of this study was to assess an informatics system that assigned curriculum meta-tags with time-based relative educational value units (ReVUs) to each clinical procedure performed by Medical University of South Carolina (MUSC) students.

Evaluation of the effect scan pattern has on the trueness and precision of six intraoral digital impression systems.

Objective: Clinicians have been slow to adopt digital impression technologies due possibly to perceived technique sensitivities involved in data acquisition. This research has two aims: determine whether scan pattern and sequence affects the accuracy of the three-dimensional (3D) model created from this digital impression and to compare the 5 imaging systems with regards to their scanning accuracy for sextant impressions.

Materials And Methods: Six digital intraoral impression systems were used to scan a typodont sextant with optical properties similar to natural teeth.

Microgrooves on titanium surface affect peri-implant cell adhesion and soft tissue sealing; an in vitro and in vivo study.

Purpose: With the significance of stable adhesion of alveolar bone and peri-implant soft tissue on the surface of titanium for successful dental implantation procedure, the purpose of this study was to apply microgrooves on the titanium surface and investigate their effects on peri-implant cells and tissues.

Methods: Three types of commercially pure titanium discs were prepared; machined-surface discs (A), sandblasted, large-grit, acid-etched (SLA)-treated discs (B), SLA and microgroove-formed discs (C). After surface topography of the discs was examined by confocal laser scanning electron microscopy, water contact angle and surface energy were measured.

Predicting marginal fit of CAD/CAM crowns based on the presence or absence of common preparation errors.

Statement Of Problem: Confusion exists as to what constitutes an ideal ceramic crown preparation and whether certain deviations from the ideal can affect the marginal fit of the milled restoration.

Purpose: This study evaluated the marginal gap of E4D crowns fabricated on preparations completed by clinicians with varying levels of expertise to identify whether common errors affect marginal fit.

Material And Methods: The fit of 75 crowns fabricated with the E4D system on preparations of varying quality were examined for marginal fit by using the replica technique.

Composite resin layering and placement techniques: case presentation and scientific evaluation.

Unlabelled: Composite resin technology has evolved, providing clinicians with the ability to deliver more natural-looking restorations for their dental patients. The evolution of layering techniques and internal staining procedures has further improved composite resins' potential for optimal results. This article discusses difficulties associated with traditional composite layering and staining, and it presents in vitro research that supports a novel layering approach.

Treatment planning processes in dental schools.

Treatment planning is a critical aspect of clinical education in the dental school curriculum. It is surprising, therefore, that so little attention has been given to this subject in the dental literature. The importance of treatment planning is reinforced in the standards and the tests that clearly present methods and necessity for treatment planning.
