Two simplified tooth sample preparation methods for conventional laboratory and RapidHIT™ ID workflows.

Disaster victim identification (DVI) refers to the forensic identification of unknown individuals following a mass disaster event. Human dental structures can contain viable DNA sources when other soft tissues are compromised. However, labor-intensive sample preparation performed by extensively trained personnel is needed to expose the nuclear material for traditional forensic DNA workflows.

Effect of Er:YAG laser on debonding zirconia and lithium disilicate crowns bonded with 2- and 1-bottle adhesive resin cements.

Introduction: Erbium-doped yttrium-aluminum-garnet (Er:YAG) laser debonding of zirconia and lithium disilicate restorations is increasingly used for a range of clinical applications.

Er:YAG laser debonding of zirconia and lithium disilicate restorations.

Statement Of Problem: Yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) restorations of different formulations are being used increasingly in monolithic form for a range of clinical applications. Using rotary instruments to remove such restorations for any purpose is challenging, but they can be removed conservatively with erbium lasers. However, studies on how a laser penetrates different zirconias to break the cement bond between the tooth surface and the zirconia are lacking.

Postpartum readmissions for hypertensive disorders in pregnancy during the COVID-19 pandemic.

Background: Hypertensive disorders in pregnancy are one of the most common causes of readmission in the postpartum period. Because of the COVID-19 pandemic, early hospital discharge was encouraged for patients who were medically stable, because hospitalization rates among SARS-CoV-2-infected patients steadily increased in 2020. The impact of an early discharge policy on postpartum readmission rates among patients with hypertensive disorders in pregnancy is unknown.

Specimens underwent crown removals by a rotary handpiece, or erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser.

Comparison of Accuracy and Time for Four Implant Placement Techniques Supporting Fixed-Partial Denture.

Various guiding methods are used to place implants. This ex vivo pilot study used a convenience sample to examine time and accuracy for placement of 2 dental implants supporting a 3-unit fixed prosthesis on a simulation model using freehand and 3 guided placement techniques. Four operators with no prior implant placement experiences were randomly assigned placement of 2 maxillary or mandibular implants for a fixed prosthesis.

Non-human Primate as an Animal Model for Testing Efficacy of Amixicile as a Targeted Anti-periodontitis Therapy.

Periodontitis is an inflammatory condition triggered by selected oral microbiota; thus treatment strategies should be aimed at reducing the abundance of the pathogenic bacteria. An obstacle to preclinical testing of such strategies is the availability of reliable animal models. Here, a non-human primate (NHP), , was used to examine the effectiveness of a novel antimicrobial, amixicile, which inhibits pyruvate-ferredoxin oxidoreductase (PFOR) present in anaerobic bacteria.

Tracking Tag Stabilization With a Small-Diameter Implant in an Edentulous Mandible to Assist Dynamically Navigated Surgery: A Case Report.

This report describes the use of a temporary dental implant to secure a radiographic fiducial marker and patient-tracking tag to an edentulous mandible for dynamically guided implant placement into a fibula microvascular free flap. A small-diameter dental implant was placed into the anterior mandible to secure a radiographic fiducial marker followed by a patient tag. The patient tag allowed for tracking of the patient's mandible during placement of endosseous dental implants.

Multiple Idiopathic Cervical Root Resorption: A Challenge for a Transdisciplinary Medical-Dental Team.

The goal of this perspective article is to use multiple idiopathic cervical root resorption (MICRR) as a model to demonstrate the need for transdisciplinary collaborations, from basic science to treatment planning, to improve the quality of health care for all. This is not a review of the literature on the current state of MICRR. Tooth root resorption is a normal physiological process required for resorption and exfoliation of primary teeth; however, root resorption of adult teeth is largely pathological.

Evaluation of Er:YAG and Er,Cr:YSGG laser irradiation for the debonding of prefabricated zirconia crowns.

Background: Reduced tooth structure in the pediatric and adolescent population is frequently restored with prefabricated zirconia crowns. On permanent teeth, these restorations may need to be removed and replaced with permanent restorations.

Objectives: To explore and compare the use of 2 high-powered erbium lasers for removing prefabricated zirconia crowns from molar teeth as a non-invasive alternative to rotary instruments.

A modern measles outbreak: understanding maternal immunity and impact on postpartum vaccination uptake.

Background: In October 2018, a measles (rubeola) outbreak was identified in New York City and Rockland County, and a public health campaign and hospital policy changes were made to increase awareness of the importance of vaccination and increase vaccination rates.

Objective: We describe the prevalence of rubeola immunity in pregnant women and the change in uptake of postpartum measles, mumps, and rubella vaccination before and during the measles outbreak.

Study Design: A multipronged intervention was developed by the health system with the intent of raising awareness of the outbreak, identifying patients at risk of contracting measles during pregnancy, and limiting exposure of inpatients to the disease.

In total, 42 implants were placed in simulation jaw models with the 2 drilling techniques by 2 operators who had previous experience with dynamic navigation. The timing of each implant placement was recorded, and horizontal, vertical, and angulation discrepancies between the planned and placed implants were compared.

Exploring the use of pulsed erbium lasers to retrieve a zirconia crown from a zirconia implant abutment.

Background: Removal of cement-retained implant fixed restorations when needed, can be challenging. Conventional methods of crown removal are time consuming and costly for patients and practitioners.

Using Er:YAG laser to remove lithium disilicate crowns from zirconia implant abutments: An in vitro study.

Background: When implants are restored with cement-retained restorations, prosthetic retrievability can be difficult and often requires sectioning using rotary instruments. Sometimes repeated removals of a cement-retained implant crown are needed such as for treatment of peri-implantitis or immediate implant provisionalization. The purpose of this study was to evaluate the effect of erbium-doped yttrium aluminum garnet (Er:YAG) laser as a non-invasive treatment modality to remove lithium disilicate crowns from zirconia implant abutments following long-term cementation, repetitive debonding and re-cementation, and short-term retrieval.
