Artificial intelligence technology powers award-winning clinical research

TORONTO, Ontario, CANADA: Dentists can expect to do better than ever before in catching undiagnosed or overlooked conditions and identifying pathologies, thanks to radiographic analysis available from Denti.AI, according to new clinical research disclosed by the company.

The American Academy of Oral and Maxillofacial Radiology awarded its 2020 Albert G. Richards Graduate Student Research Award to a University of North Carolina Adams School of Dentistry graduate student who showed the artificial intelligence software often accurately identified pathoses missed by board-certified dental experts, Denti.AI reported.

Manal Hamdan, DDS, conducted the study, titled “Detecting Apical Radiolucencies Using Deep Learning Technology: A Pilot Study.” She concluded that Denti.AI’s technology had comparable or improved results, and the artificial intelligence tool has the potential to reduce provider fatigue and diagnostic errors. Her poster on the same research won first prize for the best scientific poster at the AAOMR annual session, according to Denti.AI.

Dr. Don Tyndall, professor of oral and maxillofacial radiology at the Adams School of Dentistry, stated, “Dr. Hamdan’s research is an excellent example of university and business collaboration utilizing experts in radiology, deep learning and statistical analysis to produce clinically relevant and potentially game changing results validating software that can elevate patient care.”

“Our team at Denti.AI is committed to being at the forefront of implementing artificial intelligence into clinical practices through rigorous academic validation and collaboration with leading academic institutions,” said Dmitry Tuzoff, founder and CEO of Denti.AI.

This is the second academic award the company’s product has received this year. The University of Louisville awarded first prize to a separate clinical study featuring Denti.AI’s technology, the company said.

“We are building technology to help support oral health providers by bringing clarity, standardization, quality assurance, efficiency, and trust to the dental marketplace,” said Eric Pulver, DDS, the chief dental officer of Denti.AI.

With Denti.AI’s radiograph analysis, providers will catch more pathologies and help patients better understand the need for treatment to increase both quality of care and case acceptance, according to the company. Denti.AI’s cloud-based software centralizes the clinical data into its analytics platform, which makes it easy to see business performance in relation to hard clinical data, according to the company. Plus, its patent-pending auto-charting technology incorporates the radiographs directly into the clinical workflow, which improves operational efficiency, the company said.

Thanks to the AI-powered medical imaging technology, dental practices gain profitability, speed and quality, the company said. With Denti.AI, it only takes several seconds to interpret a series of intraoral X-rays or a panoramic image and produce a complete dental chart. Based on the experience of professional radiologists who participated in the training of the algorithms, Denti.AI looks to find what the naked eye often cannot.

Denti.AI is a software company that leverages AI analysis of dental X-rays to detect key abnormalities, past dental treatments, and other relevant features to find problems earlier and improve productivity, the company said. Its cloud-based service is integrated with a range of practice management software and imaging equipment, automating the clinical workflow of dental support organizations across North America.

TA-I Technology (TPE:2478) Has Rewarded Shareholders With An Exceptional 304% Total Return On Their Investment

The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But when you pick a company that is really flourishing, you can make more than 100%. One great example is TA-I Technology Co., Ltd. (TPE:2478) which saw its share price drive 176% higher over five years. Also pleasing for shareholders was the 17% gain in the last three months. But this move may well have been assisted by the reasonably buoyant market (up 12% in 90 days).

Check out our latest analysis for TA-I Technology

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, TA-I Technology achieved compound earnings per share (EPS) growth of 22% per year. That makes the EPS growth particularly close to the yearly share price growth of 23%. This indicates that investor sentiment towards the company has not changed a great deal. Indeed, it would appear the share price is reacting to the EPS.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for TA-I Technology the TSR over the last 5 years was 304%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

We're pleased to report that TA-I Technology shareholders have received a total shareholder return of 55% over one year. That's including the dividend. That gain is better than the annual TSR over five years, which is 32%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.

After finding glitch, Massachusetts suspends use of controversial camera system that lets police track cars

Massachusetts public safety officials have halted the use of a controversial license plate surveillance system after finding a glitch with the technology that caused it to record inaccurate data for more than five years, according to a memo obtained by the Globe.

The inaccuracies were found within a network of high-speed cameras installed by the Massachusetts State Police that automatically photograph the license plates of vehicles along roads across the state. The data, including location, date, and time, is compiled in a massive database — all without obtaining warrants or court orders.

The breadth of the newfound problem — and the impact it will have on an untold number of criminal cases — was not immediately clear Wednesday.

Attorneys quickly called on state officials to provide more details about past and ongoing criminal cases that may be impacted by the inaccurate data. Meanwhile, privacy advocates said the problem is a prime example of why lawmakers should step in to better regulate law enforcement’s use of the technology.

“Like with facial recognition and other newer forms of surveillance, there’s too many risks that something will go wrong if this is left entirely to the executive branch of the government to run secret,” said Kade Crockford director of the Technology for Liberty Program at the American Civil Liberties Union of Massachusetts. “We have to remember that these technologies are not perfect and they are never going to be perfect.”

The state’s Executive Office of Public Safety and Security issued the memo Wednesday to state criminal justice agencies and defense attorneys. In it, officials said the problem was discovered on Nov. 12 by State Police officials who were reviewing data collected by the automated license plate readers, or ALPRs.

The memo noted that the problem only affected cameras mounted in fixed locations, and did not affect plate-reader cameras installed on police cruisers. The problem also did not affect a separate network of cameras mounted above some toll roads.

State officials declined to directly answer questions or provide more details. Officials in Governor Charlie Baker’s office did not immediately respond to a request for comment.

In a statement, State Police spokesman David Procopio said: “The Department will continue to assist in verifying date and times stamps using additional retained data while working with the vendor on potential solutions.”

The camera vendor, Neology Inc., did not respond to a request for comment Wednesday.

The memo said use of the cameras was suspended shortly after the problem was found last month and “will not be utilized until further notice.”

Officials found that the date and time stamps on some photographs captured by the system dating back to May 2015 were wrong, according to the memo. The glitch occurred if a camera had lost power, then regained power and started snapping pictures before it had reconnected to servers that update the camera’s date and time settings.

The memo warned that dates and times for photographs captured in the last 5 ½ years “should not be relied upon in the absence of information supporting the accuracy of that date and time, such as upload date and time information recorded by the host server or other corroborative evidence.”

The memo said state officials may be able to verify the accuracy of some of the data by cross-referencing data with information uploaded to the state’s data servers. But that data is only available dating back to November 2019.

Plate reader technology has proliferated across the country in recent years.

In 2015, state officials in response to a request from the ACLU estimated there were 170 fixed and mobile plate reader cameras in use around the state. More recently, officials have refused to disclose the total number of cameras in the state and their locations, but did tell the Globe in July that State Police alone owns or has access to 67 fixed and mobile plate readers.

Authorities have said plate readers allow them to track either the historical or real-time movements of violent suspects or drug traffickers, for example, or to find missing and abducted people.

Meanwhile, civil liberties advocates and some lawmakers have raised privacy concerns and questions about the constitutionality of police using the technology. They’ve also expressed concern over the technology’s use by private companies, including car repossession firms and parking lot operators, and the practice of other businesses, such as banks, insurers, and private investigators, buying data from brokers.

But the technology remains unregulated in many states, including Massachusetts.

The matter was recently challenged before the state’s Supreme Judicial Court in a case in which police received alerts any time an alleged drug dealer drove over the Bourne or Sagamore bridges.

The SJC ruled in April that use of the technology does not violate privacy protections — under limited circumstances. But the court cautioned that it might elevate privacy issues in future cases if law enforcement agencies start using information collected by plate readers without proper justification.

Paul Bogosian, the defense attorney who brought that case to the SJC, said the latest revelation has serious implications not only for his client, whose case is still proceeding to trial in Barnstable Superior Court, but also for an untold number of other defendants who face charges based on investigations that involved plate reader data.

“How many times have these camera images been relied upon to prosecute a person?” Bogosian said.

Bogosian said the memo raises a host of questions, including how frequently the cameras lost power over the years and captured inaccurate time stamps as a result. He also wondered how the problem went undetected for years.

“How is it that they missed this? It’s a little hard to believe,” he added. “I don’t think this memo is telling us everything. There’s got to be something deeper.”
