Abstract

Background: Advent of Cone Beam Computed Tomography (CBCT) in dentistry has brought us to a new era of precise imaging. Radiographic evaluation of a CBCT image is more informational when compared to CT. The density measurements in CBCT images are based on greyscale values, which are more accurate in CT and these values are inconsistent across various CBCT machines. Hence, we aim at standardizing a single CBCT scanner to evaluate or determine tissue density from the greyscale values.

Methods: A total of 8 halves of undamaged, dry goat mandibles are included in the study. Scans of the bone are obtained using the KODAK CBCT unit and the PHILLIPS CT machine respectively. Densities are evaluated at 96 points on both the CT scans and the CBCT scans, respectively, using the Radiant Dicom viewer. The obtained data is entered into the excel spreadsheet and subjected to statistical analysis.

Results: The greyscale values are obtained from each of the CBCT scans. Hounsfield units are calculated from CT images coinciding with the same points on CBCT scans. The collected data is subjected to linear regression analysis and an equation is derived to determine Hounsfield units (calculated HU units) from greyscale values of CBCT images. We found no significant difference between the mean original HU units and the mean calculated HU units, thus making the equation reliable for calculating HU units from CBCT greyscale values.

Conclusions: Our results conclude that the technique was effective in calculating the Original density of tissues using grey standards of CBCT scans.

Child abuse and the role of a dentist in its identification, prevention and protection: A literature review

SINGH, Vishwendra; LEHL, Gurvanit. Child abuse and the role of a dentist in its identification, prevention and protection: A literature review. Dental Research Journal, [S.l.], v. 17, n. 3, jul. 2020. ISSN 2008-0255. Available at: <http://drj.mui.ac.ir/index.php/drj/article/view/2111>. Date accessed: 09 Jul. 2020.

Abstract

Child abuse, a reprehensible act, pervades all strata of society. Dentists are more likely to encounter
such cases in their daily practice. However, such cases usually go unreported due to lack of adequate
knowledge. Practitioners flinch from reporting these due to various reasons, and this sets up a vicious
cycle which traps the victim leading to grave long‑term consequences. This review aims to collect
all literature available on PubMed, PubMed Central, MEDLINE, Google Scholar, and Google search
engines on the role of dentists in child abuse identification and information and summarize these
details. The review will shed light on the identification of abuse in dental settings, the various legal
recourses and organizations related to it, and how dentists can better equip themselves to tackle
such cases if they come across one. The review also makes certain recommendations by which
dentists and healthcare providers in general can better prepare themselves for such contingencies.

The Use of PRF for Hard and Soft Tissue Grafting

T

Current Oral Health Reports (2020)Cite this article

Abstract

Purpose of Review

The use of platelet-rich fibrin (PRF), a second-generation platelet concentrate, has gained popularity in the field of oral regenerative surgery. This review presents data from published clinical trials on outcomes from PRF application in regeneration of infrabony defects, implant site development, and mucogingival surgery.

Recent Findings

When PRF is used for regeneration of infrabony defects, minor improvements are noted in the clinical parameters that in the majority of the cases does not reach the level of statistical significance. The use of PRF appears to limit the dimensional changes of the alveolar ridge after tooth extraction when compared with sockets that are allowed to heal with no grafting. When combined with coronally advanced flaps (CAF) for root coverage, PRF shows a slight advantage over CAF alone.

Summary

Despite the adequate volume of publications in the field, the limitations of the existing studies highlight the need for high level of evidence to support the significant benefit of PRF in hard and soft tissue within the scope of periodontal and peri-implant surgery.

DS 2021: Statement by Oliver Frese, Chief Operating Officer of Koelnmesse, regarding Dentsply Sirona

#idscologne

Statement by Oliver Frese, Chief Operating Officer of Koelnmesse, regarding Dentsply Sirona

"We regret the cancellation that we have received from Dentsply Sirona for the coming IDS 2021. The management of the US-American group informed us in a personal dialogue that unfortunately the current effects of the global Corona crisis have made this step unavoidable. At the same time, Dentsply Sirona expressly underlined the role of IDS as the leading international trade fair and assured that it would be participating at future events.

We, Koelnmesse and the GFDI Gesellschaft zur Förderung der Dental-Industrie mbH, the commercial enterprise of the VDDI (Association of German Dental Manufacturers e.V.) are totally convinced that IDS 2021 will do justice to its decisive role as the leading global trade fair in ensuring a successful re-start of the industry after the acute phase of the Corona crisis has eased. The industry needs a strong driver precisely now, which under the best possible framework conditions will guarantee a safe, personal exchange and thus provide impulses for new business. All the more so since a large share of the exhibitors of IDS are medium-sized companies, which are reliant on the urgently needed economic effects that ensue from the appeal of a strong marketing platform.

The remaining eight months until IDS 2021 is staged in mid-March give us time to further prepare all of the measures necessary for a successful and safe event. We have over the past months in the course of intensive processes and in close collaboration with all of the relevant authorities developed a wide-ranging concept for the re-start of the trade fairs in Cologne under the title #B-SAFE4business. Following this concept, IDS will also inspire the dental business amid the conditions of the new normality."

About IDS

IDS (International Dental Show) takes place in Cologne every two years and is organised by the GFDI Gesellschaft zur Förderung der Dental-Industrie mbH, the commercial enterprise of the Association of the German Dental Industry e.V. (VDDI) and is staged by Koelnmesse GmbH, Cologne.

2C MEDTECH Launches CASPR Compact Medik and HVAC Solutions to Reduce Airborne and Surface Pathogens by up to 99.96%

CASPR Medik Technology Has Been Proven in Hospitals to Provide Continuous, Safe Disinfection in Occupied Space

Dallas, TX – July 27, 2020 –  2C MedTech, a healthcare product developer and distributor specializing in commercializing real innovations with true impact, is partnering with CASPR™ Group to introduce CASPR’s next generation disinfection technology to dental offices across the globe.

Previously only available to hospitals as an in-duct HVAC product, CASPR Medik™ is now available to dental offices as an HVAC solution as well as a new portable unit called CASPR Compact Medik.

CASPR, which stands for Continuous Air and Surface Pathogen Reduction was originally developed for hospitals, to reduce the risk of Healthcare Associated Infections (HAIs). Given the heightened awareness of the risk to dental professionals from Aerosol Generating Procedures, CASPR chose to make the CASPR Medik products available to dental offices.
At the heart of the CASPR system is its Medik disinfection technology which reacts with the H2O molecules found in the air to continuously create highly effective oxidizing molecules such as hydrogen peroxide (H2O2).
These molecules are delivered at safe levels to reduce clinically relevant pathogens, including viruses. CASPR is safe for use in occupied space and does not interrupt patient care.
“CASPR Medik is a great option for dental offices concerned with reducing air and surface pathogens.” says 2C MedTech CEO, Lea Ellermeier. “The new CASPR Compact Medik is plug and play. it is easy to install and virtually silent.”
According to practicing dentist and CDC consultant Dr. Margaret Scarlett, “When it comes to controlling pathogens associated with dental aerosols, CASPR Medik technology can be a highly-effective first line of defense.”
The main benefits of CASPR Medik technology include the following:
Up to 99.96% kill rate of bacteria, viruses, and molds on surfaces
Provides continuous air and surface protection
Safe for use in occupied spaces like waiting rooms and operatories
Proven to be highly effective against pathogens, odors, and VOCs

The mobile version of the technology, CASPR Compact Medik, is small, portable, and easy to deploy where needed in dental offices of all sizes.  Each unit can cover an area up to 1,500 square feet and has a list price of $1,850. The product is available for pre-order and is expected to ship mid-August.  CASPR in-duct units are priced according to the square footage of the area where they are deployed. Both versions of CAPR Medik can be ordered at www.2cmedtech.com.
