Year : 2018  |  Volume : 10  |  Issue : 2  |  Page : 112-116

Introduction:
The goal of modern dentistry is to prevent tooth loss and provide a healthy dentition with optimal functional efficiency, structural balance, and aesthetic harmony. The placement of an implant immediately after tooth extraction helps to maintain the bone crest and leads to ideal implant positioning from a prosthetic point of view and has the potential of decreasing the total treatment time for patients.  

Aim and Objective: To evaluate the platelet rich fibrin with or without bone ceramic on soft issue and crestal bone in one stage implant placement in fresh extraction socket.  

Materials and Methods: A total of 30 patients were randomly assigned into two groups—each group comprising 15 patients based on platelet-rich fibrin with and without bone ceramic and one-stage implant placement in fresh extraction socket. All patients were prospectively evaluated clinically and radiographically. All the data were analyzed using a software statistical package for social sciences (SPSS) version 11.5 (Chicago, Illinois, USA).  

Results: During the 6-month interval, no implant was lost; the mean bone level at the implants increased in platelet-rich fibrin (PRF) with bone ceramic group and decreased in PRF group and papillary index increased in both the groups, whereas modified sulcus bleeding index and probing pocket depth (PPD) decreased in both the groups.

 Conclusion: It can be concluded that mean crestal bone levels increased in PRF with bone ceramic group, whereas decrease in PRF group and both the groups are statistically significant. When the papillary levels are compared between the two groups, there was no statistical significance, but increased papillary levels were found in both the groups. The mean PPD was decreased in both the groups, but there was no statistical significance between the two groups.

Interplay between toothbrush stiffness and dentifrice abrasivity on the development of non-carious cervical lesions

Original Article

First Online:

Abstract

Objective

This study investigated the effect of toothbrush stiffness and dentifrice slurry abrasivity on the development and progression of simulated non-carious cervical lesions (NCCLs).

Materials and methods

Human maxillary premolars were allocated to 12 groups generated by the association between toothbrushes, soft, medium, and hard stiffness, and simulated dentifrice slurries, lower, medium, and higher; deionized water (DI) served as negative control. Teeth were mounted on acrylic blocks, and their root surfaces partially covered with acrylic resin to simulate gingiva, leaving a 2-mm area apical to the cemento-enamel junction exposed to toothbrushing. Specimens were brushed with the test slurries for 35,000 and 65,000 double strokes. Impressions taken at baseline and after both brushing periods were scanned by a 3D optical profilometer. Dentin volume loss (mm3) was calculated by image subtraction. Data were analyzed using three-way ANOVA and Fisher’s PLSD tests.

Results

All toothbrushes caused higher volume loss when associated to higher abrasive slurry, compared to medium- and lower-abrasive slurries. Medium caused more volume loss than lower-abrasive slurry, which led to more volume loss than DI. Hard and medium toothbrushes were not different when used with medium- or higher-abrasive slurries. There were no differences among toothbrushes when used with DI and lower-abrasive slurry. Overall, 35,000 brushing strokes resulted in significantly less volume loss than 65,000.

Conclusions

Toothbrush stiffness was an important factor on NCCL development, especially when brushing with medium- and higher-abrasive slurries.

Clinical relevance

Medium and hard toothbrushes associated with medium- and high-abrasive toothpastes can yield more severe NCCLs.

Carestream Dental Hosts Official Ribbon Cutting for New Global Headquarters


ATLANTACarestream Dental today welcomed its more than 400 Atlanta-based employees and their guests to its new global headquarters at 3625 Cumberland Blvd., with an official ribbon-cutting ceremony. 
The ribbon cutting featured distinguished guests from the health and dental communities, including Dikembe Mutombo, representing the Dikembe Mutombo Foundation, which is dedicated to improving the health, education and quality of life for the people of the Democratic Republic of the Congo, and Sheri Anderson, representing the Dentistry for the Developmentally Disabled Foundation, which provides specialized oral healthcare to patients with developmental disabilities in Metro Atlanta.
Representatives from the county and metro chambers of commerce, including Sharon Mason, president and CEO, Cobb Chamber, and Rob Demont, director of bioscience/healthcare, Metro Atlanta Chamber, were also in attendance to speak to Carestream Dental’s role in expanding Atlanta’s position as a global healthcare hub.
“This move has reminded us that Carestream Dental has an important role to play across several communities,” Lisa Ashby, CEO, Carestream Dental, said. “First, our employees make up a tight-knit community that is accountable to each other and our customers. Second, our role in the local community, providing jobs and impacting the economy. Third, and most importantly, Mr. Mutombo and Ms. Anderson reminded us that we’re a part of a greater healthcare community that changes lives around the world.”
CSD HQ, as it’s known, is Carestream Dental’s new global headquarters. The company transitioned to the 54,000 sq. ft. office space on Dec. 17, 2018 but made the move official with the Jan. 7, 2019 ceremonial ribbon-cutting. CEO Lisa Ashby and Mr. Mutombo had the honor of cutting the ribbon on a specially made staircase that connects the two floors of the office.

Carestream Dental Expands CS 3600 Capabilities with exocad Software Interaction

ATLANTACarestream Dental has partnered with exocad, a third-party dental CAD/CAM software solutions provider, to offer direct interaction with the CS 3600 intraoral scanner. This allows clinicians to capture digital impressions directly from exocad ChairsideCAD software.
Practitioners using the CS 3600 intraoral scanner are now able to launch digital impression scans directly from exocad’s database software. Once acquired, the data set is automatically stored in the exocad database and can be immediately processed in exocad’s ChairsideCAD software. This new interaction streamlines the process of capturing the dataset and designing the restoration in exocad’s software and allows the doctor to work solely within the exocad environment, eliminating the need to import or transfer the dataset.  
“Carestream Dental understands the timesaving effect reducing clicks in software can have,” Ed Shellard, D.M.D., chief dental officer, Carestream Dental, said. “Fortunately, the open architecture of the CS 3600 means that it has always worked well with exocad, however, we’re continuously looking for new ways to improve upon workflows. This new partnership with exocad makes the interaction even more seamless, helping doctors work more efficiently.”

The CS 3600 creates precise, detailed HD 3D digital impressions that are highly accurate, while offering an easier acquisition method than using traditional PVS impressions. The scanner’s high-speed continuous scanning makes capturing dual arches faster and easier. Plus, ergonomically-designed, rounded autoclavable and reusable tips lead to a more comfortable and hygienic scanning experience for patients.

Interaction with exocad’s design software ChairsideCAD provides oral health professionals with direct access to world-class restorative design software. ChairsideCAD is the first complete open-architecture CAD/CAM software platform for single-visit dentistry. The chairside workflow is streamlined, easy to learn, and optimized for usage in the practice, including a step-by-step guide through the design process. It’s based on the same proven technology as exocad’s ‘best-of-breed’ lab software, renowned for its reliability and robust features. In just a few steps, exocad ChairsideCAD creates highly aesthetic proposals with minimal post processing.
“The cooperation with Carestream supports our goal to provide technology that helps clinicians take maximum advantage of digital processes”, Tillmann Steinbrecher, exocad CEO, said. “With this new interaction, we provide CS 3600 users a seamless workflow from scanning to designing. Thanks to our software and the smooth interaction, we help customers to maximize the return on their hardware investment”.

Suni Closes Its Doors! An Open Letter to the Suni Imaging User Community from Apteryx, Inc.

Published on January 8, 2019
Apteryx, Inc, Akron, Ohio –
Dental Colleagues, Customers, and Partners,
Since the first of the year, rumors and concerns have been circulating in the dental community about the on-going operations of Suni Medical Imaging — an Apteryx reseller partner. As dentists, you may know them better as Dr. Suni. Since 2002, they have installed thousands of practices with Dr. Suni and Prof. Suni, which are their brand names for Apteryx’s XrayVision imaging software.
It has been rumored that as of January 1, Suni has discontinued operations. Since learning of this news last week, we have reached out to Suni leadership to clarify the situation without a response. In the interest of getting the facts straight, we will continue our efforts to contact Suni directly. However, we feel an immediate obligation to reassure Suni customers that their software and support needs will continue to be met by Apteryx.
Over the next several weeks, Apteryx will proactively contact practices where we know that XrayVision software, sold under Suni’s Dr. Suni and Prof. Suni labels, has been installed. Since we don’t have direct visibility to everyone, we invite all Suni customers to call us at (877) 278-3799 for your immediate support needs and to register for on-going support. Suni customers may also email us at support@apteryx.comor visit www.ledapteryx.com/suni.
As Suni/ XrayVision customers, please rest assured that you are well positioned to make whatever transitions may be required. Dr. Suni and Prof. Suni, like all Apteryx XrayVision products, are designed as an “open” system meaning that you have plug and play interoperability with other open hardware and software solutions. XrayVision is used by over 30,000 practices in the U.S. alone and continues to be actively developed and enhanced — in fact, Suni customers have not yet received our latest version, XrayVision 4.0. We also offer a cloud-based upgrade path via our XVWeb product, which received FDA clearance for our 3D module in late 2018.
Most importantly, know that as a leading provider of imaging solutions since 1995, we understand just how important your imaging system is to your practice. Apteryx stands behind XrayVision and our entire product line, whether sold direct or by our reseller partners. We are ready to support the Suni user community with our team of imaging experts and ensure stability for your practice.
