Guidelines for Selecting the Implant Diameter During Immediate Implant Placement of a Fresh Extraction Socket: A Case Series.

Int J Periodontics Restorative Dent. 2016 May-Jun;36(3):401-7. doi: 10.11607/prd.2381.


This prospective case series proposes a method for selecting the diameter of immediate postextraction anterior implants and guiding the placement position of the implant based on the buccolingual dimension with the goal of preserving the buccal bone wall. The socket buccolingual distance was measured to determine the appropriate implant diameter, considering a 3-mm gap to the buccal wall. Pre- and postoperative cone-beam computed tomography images were compared to evaluate the buccal bone. The socket width measurements were not significantly different (P = .931). The mean widths of the postoperative buccal bone were 3.01 ± 0.18 mm, 2.92 ± 0.38 mm, and 2.83 ± 0.42 mm for the crestal bone at the implant platform and at 2 and 4 mm apically, respectively, after 35 months of follow-up. This new diameter selection method for implants demonstrated predictable buccal plate preservation.

Influence of Thermo-Light Curing with Dental Light-Curing Units on the Microhardness of Glass-Ionomer Cements.

This quick tip is good to know MJ
Int J Periodontics Restorative Dent. 2016 May-Jun;36(3):425-30. doi: 10.11607/prd.2405.


The purpose of this study was to verify for various glass-ionomer cement (GIC) products whether the application of thermo-light curing on the initial curing material produces an increase in microhardness, and to determine whether this hardness varies depending on the depths of the GIC samples. The efficacy of various polymerization units on this additional hardening was also examined. The GIC samples were thermo-light cured for 60 seconds with three polymerization units. The Vickers microhardness was measured at three different depths: 2 mm, 3 mm, and 4 mm. Analysis of variance and Newman-Keuls test showed statistically significant differences among tested samples for all three GIC groups (P < .001). The results of linear regression analysis showed a statistically significant relationship between the hardness of the material and the temperature for samples with depths of 2 mm (R = 0.78; P = .0028) and 3 mm (R = 0.59; P = .045). The findings of this study indicate that thermo-light curing of GIC with different polymerization units for 60 seconds during setting reaction increases the microhardness of the GICs at all depths tested and may increase resistance to mastication forces, which can be validated in future clinical studies.

American Dental Association Mails Malware Infected USBs to Dentists Nationwide

The American Dental Association (ADA) has unintentionally mailed 37,000 USB flash drives, laced with malware, to dental offices across the U.S.
According to, the problem was initially found in a post by a DSL Reports Security Forum member. Krebs wrote, that a “Mike” from Pittsburgh… “looked at the code inside one of the files on the flash drive and found it tries to open a webpage that has long been tied to malware distribution. The domain is used by crooks to infect visitors with malware that lets the attackers gain full control of the infected Windows computer.”

The ADA speculates that one of several duplicating machines in use at the manufacturer had become infected during one of its production runs. The association sent an email to its members alerting them about the infected flash drives, also noting that a computer’s antivirus software should detect any present malware… keyword there being “should”.

Joe Dahlquist, Product Manager of ThreatSTOP says, “The deployment of the malware was well executed, and allowed for a rapid proliferation of already difficult to detect software into a trusted network. Once plugged into a computer, the malware could – potentially – execute in the background, and go to work. This makes it both exceptional at doing what it does, and difficult to prevent what it specializes in: data theft. While the exact purpose of this security attack given is currently unknown to us, it’s safe to assume that the main goal was likely to export sensitive data, with healthcare data fetching a premium on the black market. In the meantime, the most elegant way to prevent communications to the C&C servers in cases such as this is to implement a DNS firewall to block communication attempts to known C&C servers, be it to drop off data or to attempt to simply ask what it is the program should do.”

Dodi Glenn, VP of cyber security at PC Pitstop says, “Two immediate things come to mind here. First, the ADA should stop using removable media to send out information. Not only is it more expensive to mail a device out, it is also (obviously) less secure. Second, the ADA and their manufacturer should work together to understand how the malware got on the USB devices in the first place. Additionally, the manufacturer should contact all companies that have recently used their services, to let them know that their devices may also be infected.”
Stu Sjouwerman, CEO of KnowBe4 says, “This is a clear case where effective security awareness training would have prevented malware infections caused by infected USB devices. Anyone that has stepped through our training would think twice before plugging a device like that into their computer.”

CS 3600 Intraoral Scanner Makes Capturing Dual Arches Faster and Easier than Ever

ORLANDO, Fla.—When it comes to intraoral scanning for orthodontics, speed is key. That’s why Carestream Dental’s new CS 3600 intraoral scanner features optimized scanning for capturing full and dual arches in less time, plus a workflow just for orthodontists.
Users can quickly scan in a smooth, uninterrupted manner thanks to the scanner’s high speed, continuous scanning feature. Unsteady hands or fidgeting young patients have no effect on the final scan. The speed and accuracy of continuous scanning makes for more accurate digital impressions and faster, easier dual arch acquisition.
“Orthodontists see a high volume of patients each day, so chair time is at a premium,” Matt Hendrickson, director, orthodontic business, Carestream Dental, said. “The CS 3600’s high speed scanning makes it easy to create a digital model in a fraction of the time compared to a traditional impression. Naturally, digital scanning also guarantees a more precise model than a traditional impression could.”
In fact, the CS 3600’s scans have been tested for accuracy by ClearCorrect and are now accepted for use with all of ClearCorrect’s products. Additionally, the scanner’s precision has been validated by American Orthodontics (AO) for use with the Harmony digitally customized self ligating lingual bracket system.
“We are very proud that the CS 3600 meets the high accuracy requirements necessary to work with these two great systems,” Hendrickson said. “Our open architecture file system and 'no-fees' approach make it very easy for practices to send digital impressions to the partner of their choice for fabricating appliances.”
An Intelligent Matching System also makes it easier to freely fill in missing information for any area in the data set. Rather than pausing scanning to indicate the location of the scanner in the software, the CS 3600 auto-locates the region for the user; users keep their eyes on the patient, not the computer screen.
Additionally, the CS 3600 comes with two rounded scanning tips—normal and a unique side-oriented tip. The side oriented tip is perfect for dual arch scans, as it prevents the user from having to unnaturally twist their arm to capture the full arch. Plus, the tip has the shortest height in the industry, ideal for orthodontists’ young patients with small mouths.
The CS 3600’s software also offers a workflow specific to orthodontists. Digital models are created automatically for study, record keeping or fabrication of orthodontic appliances.
“Whereas an alginate impression takes up chair time plus an additional 15+ minutes for lab time, CS Model, the scanner’s software designed specifically for orthodontists, creates bases and trims and measures bite registration automatically,” Hendrickson said. “Doctors go from scanning to case presentation faster and more efficiently.”   
The CS 3600 features HD 3D images; is lightweight; easy to carry from operatory to operatory; produces open .STL and .PLY files; and requires no click-fees.
Carestream Dental is also pleased to announce a new cutting-edge patient engagement solution for CS OrthoTrac practice management software. This new feature will help orthodontists build better relationships with their patients and market their practice effectively.
The solution features a suite of tools to facilitate interacting with patients such as texting, email marketing, online scheduling and appointment reminders. There’s also the option to monitor a practice’s online reputation on review sites and social media; track and analyze interactions with patients; and manage local listings and search engine optimization for great exposure.
“Between soccer practice and swim lessons, patients and their parents are busy,” Robert Patrick, product line management director, global dental practice management solutions business, Carestream Dental, said. “This solution lets orthodontists interact with patients in a way that’s easy and convenient for both the patient and the doctor. Plus, the practice also benefits from dashboards to track and analyze these interactions so the doctor can be assured of ROI.”
CS OrthoTrac has been the industry leader in orthodontic practice management for over 30 years and Carestream Dental is excited to help software users maximize the success of their orthodontic practices in new ways.
CS OrthoTrac users will also be excited to learn of a new online community for Carestream Dental software users: The Exchange. The Exchange allows visitors to connect with other software users and share tips and tricks within the community. They can also search a database of help files or post questions to be answered by Carestream Dental subject matter experts. The Exchange is part of Carestream Dental’s increasing efforts to make things easier for its customers. Visit The Exchange at

Dimensional Changes in Alveolar Ridge Following Extraction of Teeth in the Maxillary Premolar Area in Subjects with Thick and Thin Gingival Biotypes: A Pilot Study.

Int J Periodontics Restorative Dent. 2016 May-Jun;36(3):431-6. doi: 10.11607/prd.2209.


This study investigated changes in residual ridge dimensions after tooth extraction among thin and thick gingival biotypes. Fifteen patients who required extraction of maxillary premolars were classified according to gingival biotypes (10 teeth in 9 participants were included in the thick group, and 6 teeth in 6 participants were included in the thin group). Minimally traumatic extractions were carried out using periotomes and rotational movement of teeth. At the time of extraction an osteometer was used to measure the thickness of the labial plate and the bony alveolar ridge at the extraction site by penetrating the tissues until bone was reached 5 mm, 7 mm, and 10 mm below the midpoint of the crest of the facial and palatal gingival margins. Standardized radiographs were taken immediately and after 3 months. The results of this study show minimal differences in dimensional changes following extraction of premolar teeth in thick and thin gingival biotypes. Significantly greater bone loss was detected in both gingival biotypes when the labial plate thickness was less than 1.5 mm, especially in alveolar ridge height

Low-Income Parents' Perceptions of Oral Health and Acceptance of Mid-level Dental Providers.

J Dent Hyg. 2016 Apr;90(2):100-10.



The purpose of this study was to explore low-income parents' perceptions of oral health and of mid-level dental providers as a means of improving access to care. As states increasingly consider adding mid-level providers to the dental workforce, understanding the views of potential patients toward such providers is important, since the success of this strategy will depend, in part, upon the willingness of potential patients to be treated by them.


Because little is known about the social acceptability of mid-level dental providers, the researchers employed a qualitative methodology, conducting in-depth interviews with 20 low-income parents in order to assess their perceptions of oral health, access to and need for dental care, and potential acceptance of mid-level dental providers. Interview transcripts were analyzed by a team of researchers using interpretive research methods.


Respondents' descriptions of experiences with oral health and dental care demonstrate their strong desire to maintain their families' oral health, as well as their perception that they face significant barriers to receiving needed care. The vast majority of respondents expressed positive inclinations toward the introduction of mid-level dental providers, particularly once they understood that such providers would be fully trained professionals. Though in reality the cost to a patient would likely not vary, many respondents expressed increased interest in treatment by mid-level providers if it were less expensive than treatment by dentists, indicating the significant barrier that cost posed for many in the sample.


The low-income parents in this sample would likely seek care from mid-level dental providers if such providers were introduced in the U.S. The success of mid-level providers in meeting the needs of this population would potentially be even greater if public education clearly explained their training and professionalism.
