Occupational Noise Exposure in the Pediatric Dental Setting.

To evaluate the noise levels recorded in a hospital-based pediatric dental clinic and evaluate the occupational exposure personnel have to potentially hazardous levels of noise. A SoundAdvisor™ Sound Level Meter Model 831C was used to gather 19 days of background sound data (equivalent continuous sound levels, measured as LAeq) in the open bay, quiet room, sedation suite, and operating room settings. A Spartan™ Wireless Noise Dosimeter Model 730 (Larson Davis) was utilized to capture data about personal noise exposure of pediatric dental residents over 81 clinic sessions.

Fracture Resistance Behaviors of Titanium-Zirconium and Zirconia Implants.

Purpose: To evaluate the fracture resistance behaviors of titanium-zirconium, one-piece zirconia, and two-piece zirconia implants restored by zirconia crowns and different combinations of abutment materials (zirconia and titanium) and retention modes (cement-retained and screw-retained zirconia crowns).

Material And Methods: Three research groups (n=12) were evaluated according to combinations of abutment material, retention mode, and implant type. In the control group (TTC), titanium-zirconium implants (∅ 4.

Effects of shade and thickness on the translucency parameter of anatomic-contour zirconia, transmitted light intensity, and degree of conversion of the resin cement.

Statement Of Problem: Anatomic-contour zirconia prostheses are usually cemented with resin cement. However, information regarding the effects of the zirconia shade and thicknesses on the translucency of the prosthesis, the intensity of the transmitted light beneath the prosthesis, and the subsequent degree of conversion in the resin cement is sparse.

Purpose: The purpose of this in vitro study was to investigate the translucency parameter in 3 anatomic-contour zirconia specimens of 2 shades at 5 different thicknesses and to investigate the transmitted light intensity and degree of conversion of the resin cement beneath the ceramic specimens by using a traditional zirconia and a lithium disilicate glass-ceramic as controls.

Bonding between implant attachment pickup materials and CAD-CAM denture base material.

Statement Of Problem: Adequate bonding between pickup material and the newer generation of prepolymerized polymethyl methacrylate (PMMA) for computer-aided-design and computer-aided manufacturing (CAD-CAM) dentures is essential to the success of treatment. However, studies on the bond between these 2 materials are lacking.

Purpose: The purpose of this in vitro study was to evaluate the bond strength of 3 different chairside implant LOCATOR attachment pickup material groups and prepolymerized PMMA by investigating their pushout force.

Influences of build angle on the accuracy, printing time, and material consumption of additively manufactured surgical templates.

Statement Of Problem: Although desktop stereolithography (SLA) 3D printers and photopolymerizing resin have been used increasingly in dentistry to manufacture surgical templates, studies investigating their clinical application are lacking.

Purpose: The purpose of this in vitro study was to evaluate the effects of build angle on the accuracy, printing time, and material consumption of additively manufactured surgical templates made with a desktop SLA 3D printer and photopolymerizing resin material.

Material And Methods: Fifty surgical templates were fabricated from 1 master digital design file using a desktop SLA 3D printer and photopolymerizing resin material at 5 different build angles (0, 30, 45, 60, and 90 degrees) (n=10).

Leadership diversity in prosthodontics: Number of women and nonwhite individuals serving as President of selected prosthodontic organizations in the last 20 years.

Statement Of Problem: As a measure of the leadership diversity in prosthodontics, the number and percentage of women and nonwhite Presidents of prosthodontics organizations is unknown.

Purpose: The purpose of this observational study was to calculate and compare the number and percentage of women and nonwhite Presidents of 10 selected prosthodontic organizations over the past 20 years and to determine whether the number of women and nonwhite Presidents has changed over the time frame of 2000-2019 in comparison to male and white Presidents.

Material And Methods: The number of women and nonwhite Presidents of the Academy of Prosthodontics (AP), American Academy of Fixed Prosthodontics (AAFP), American Academy of Maxillofacial Prosthetics (AAMP), American College of Prosthodontists (ACP), American Prosthodontic Society (APS), European Prosthodontic Association (EPA), International Association of Dental Research - Prosthodontics group (IADR-P), International College of Prosthodontists (ICP), Greater New York Academy of Prosthodontics (GNYAP), and Pacific Coast Society for Prosthodontics (PCSP) was recorded.

Leadership diversity in prosthodontics: Recommendations for the representation of women speakers at scientific prosthodontic meetings.

Statement Of Problem: Leadership platforms in the professions include invitations to speak at the meetings of major organizations. However, the percentage of women speakers at prosthodontic meetings is lower than that of women prosthodontists overall. Recommendations or reporting requirements to address this deficiency are lacking.

Consideration for Contemporary Implant Surgery.

The advancement of technology often provides clinicians and patients better clinical alternatives to achieve optimal treatment outcomes. Computer-guided options allow clinicians to realize the virtual prosthodontically driven surgical plan, facilitating more predictable implant placement. Although the use of technology does not mean the clinicians can forgo the fundamental treatment principles when treating a patient, proper assessment and diagnostic approach from prosthodontic, surgical, and radiographic perspectives are still essential for a successful clinical outcome.

Maxillofacial Prosthetics.

The treatment of head and neck cancers requires a team approach. Maxillofacial prosthetics and oncologic dentistry are involved in many phases of the treatment. After the cancer ablation surgery, if surgical reconstruction cannot not completely restore the surgical defect site, maxillofacial prostheses plays an important role to rehabilitate the patient's mastication, swallowing, and speech.

Fatigue Failure Load of Lithium Disilicate Restorations Cemented on a Chairside Titanium-Base.

Purpose: To evaluate the fatigue failure load of distinct lithium disilicate restoration designs cemented on a chairside titanium base for maxillary anterior implant-supported restorations.

Materials And Methods: A left-maxillary incisor restoration was virtually designed and sorted into 3 groups: (n = 10/group; CTD: lithium disilicate crowns cemented on custom-milled titanium abutments; VMLD: monolithic full-contour lithium disilicate crowns cemented on a chairside titanium-base; VCLD: lithium disilicate crowns bonded to lithium disilicate customized anatomic structures and then cemented onto a chairside titanium base). The chairside titanium base was air-abraded with aluminum oxide particles.

Integrating a facial scan, virtual smile design, and 3D virtual patient for treatment with CAD-CAM ceramic veneers: A clinical report.

This clinical report describes a digital workflow using the virtual smile design approach augmented with a static 3-dimensional (3D) virtual patient with photorealistic appearance to restore maxillary central incisors by using computer-aided design and computer-aided manufacturing (CAD-CAM) monolithic lithium disilicate ceramic veneers.
