Research Published Showing the Canary System Can Accurately Detect Caries Beneath Opaque Fissure Sealants

Posted on October 25, 2016

The Journal of Investigative and Clinical Dentistry has published a study entitled “Comparison of The Canary System and DIAGNOdent for the in vitro detection of caries under opaque dental sealants.” This paper concluded that The Canary System can aid in the detection and monitoring of the status of tooth structure and caries beneath sealants. 

“Dental sealants are an excellent preventive tool for treating pits and fissures in posterior teeth” said Dr. Stephen Abrams, President of Quantum Dental Technologies. “Recent publications from the American Dental Association, American Academy of Pediatric Dentistry and the CDC all conclude that sealants should be an essential part of oral health care delivery. Unfortunately, over time, the bond with the fissure will degrade, allowing the ingress of oral fluids and bacteria, creating the ideal environment for caries to develop. Without The Canary System, these lesions are not detected until they have destroyed a large amount of tooth structure.”

The energy conversion technology, PTR-LUM, that powers The Canary System enabled investigators to find caries beneath 2mm. of Helioseal® F, Embraceä WetBondä, Delton®, UltraSeal XT® plusä sealants on 105 potential sound and carious pit/fissure sites on occlusal surfaces of 40 extracted human molars and premolars. Marked pits/fissures were scanned with The Canary System and DIAGNOdent before and after sealant placement. Using polarized light microscopy as the validation tool, the status (carious/non-carious) of each examined pit/fissure was confirmed. The accuracy of The Canary System was not affected by any sealant; DIAGNOdent produced a high number of false positive readings.

“Many dental sealants contain opacifying agents that exhibit intrinsic autofluorescence properties, resulting in false positives when scanned with DIAGNOdent, which uses fluorescence technology. The Canary System uses PTR-LUM technology which can ‘see through’ opaque sealants, giving clinicians a quantifiable measurement of the status of the enamel crystal structure”, said Dr. Koneswaran Sivagurunathan.

The Canary System, with its unique crystal structure diagnostics, can quantify, image, monitor and record changes in the structure of enamel, dentin and cementum. It can detect caries beneath opaque sealants, around the margins of restorations, and beneath interproximal, occlusal and smooth surfaces. The Canary Cloud enables dentists to view and manage this data and track Canary usage in the office.

Drug-Resistant and Gum Disease-Causing Germs Selectively Destroyed by PerioLase MVP-7 Dental Laser

Drug-Resistant and Gum Disease-Causing Germs Selectively Destroyed by PerioLase MVP-7 Dental Laser

1064nm wavelength selectively vaporizes bad bacteria without harming healthy tissue

CERRITOS, Calif., Oct. 24, 2016 /PRNewswire/ -- Two new research studies demonstrate how the 1064nm wavelength PerioLase® MVP-7™ dental laser system, optimized for the LANAP® protocol, selectively destroys Porphyromonas gingivalis (Pg), a "keystone" pathogen that directs other gum tissue bacteria to become pathogenically active in the progressive destruction involved in moderate to severe gum disease. 

Pg has historically been identified as a black pigmented species bacteria based on its visible color in lab cultures.  Numerous studies by Midda and others have shown that Pg is destroyed in human treatments following the use of a 1064nm pulsed Nd:YAG laser. These two observations led to conjecture that Pg was also pigmented in the body (in vivo), and that the 1064nm wavelength kills the bacteria by targeting the visible (black) pigment.

"The Black Bug Myth, Selective Photodestruction of Pigmented Pathogens" by researchers David Harris, PhD, et al., clearly demonstrates that the PerioLase MVP-7 1064nm wavelength dental laser destroys Pg bacteria regardless of the amount of visible pigmentation or complete lack of visible pigmentation in the bacteria.

This research suggests that the PerioLase MVP-7 kills Pg bacteria by destroying an invisible chromophore. In other words, periodontal bugs do not need to be black, or even visible to the human eye, in order to be eliminated by the PerioLase MVP-7.

The second study, "Selective Photoantisepsis", published by Harris and Reinisch, focuses on selectively eliminating pathogens at different depths within a tissue model by analyzing the differences between the absorption of light energy by pathogens and host tissues. The study supports selective destruction of Pg and Prevotella intermedia (Pi) at depths of 3-4mm using a 1064nm pulsed-Nd:YAG laser. Unlike the 1064nm wavelength, the 810nm diode laser requires visible pigment to destroy the bacteria. The 810nm was also lethal to the healthy tissue at an earlier stage. The model indicates no selectivity for the 2940nm Er:YAG laser.

"These two studies add to our understanding of the reasons and mechanisms for the benefits of the PerioLase MVP-7 1064nm pulsed Nd:YAG laser in reducing the periodontal pathogens associated with gum disease," states Robert H. Gregg II, DDS, co-inventor of the PerioLase MVP-7 and inventor of the LANAP protocol. "It is no surprise that positive evidence and research continue to accumulate given the consistent, reproducible results our LANAP-trained clinicians have obtained for decades."

The PerioLase MVP-7 surgical laser, included in the PerioLase Periodontal Package (PPP), is manufactured exclusively by Millennium Dental Technologies, Inc.  The PPP includes the industry's best surgical training and the only clinical results guarantee.  The patent pending LANAP® Protocol and patent pending LAPIP™ Protocol are featured techniques in the highly acclaimed surgical training program offered by Millennium and presented by the Institute for Advanced Laser Dentistry.

Both studies were published in the journal Lasers in Surgery and Medicine.

Study Suggests Benefits of Laser Treatments for Dental Problems

Posted on October 21, 2016

Researchers have developed computer simulations showing how lasers attack oral bacterial colonies, suggesting that benefits of using lasers in oral debridement include killing bacteria and promoting better dental health.

In a study published in the journal Lasers in Surgery and Medicine, the researchers show the results of simulations depicting various laser wavelengths aimed at virtual bacterial colonies buried in gingival tissue. In humans, actual bacterial colonies can cause gingivitis. Gingivitis can develop into periodontal disease, which involves a more serious infection that breaks down the bones and tissues that support teeth.

"The paper verifies or validates the use of lasers to kill bacteria and contribute to better health following periodontal treatments," said co-author Lou Reinisch, PhD, associate provost for academic affairs at New York Institute of Technology.

Drawing on his background in physics, optics, and calculus, Reinisch, an expert in laser surgery and an associate editor with the journal, created mathematical models based on optical characteristics of gingival tissues and bacteria. He then produced simulations of three different types of lasers commonly used in dentistry and their effects on two types of bacterial colonies of various sizes and depths within the gingival models.

"One of the questions we asked is how deep could the bacteria be and still be affected by the laser light," said Reinisch. The simulations indicate that 810 nm diode lasers, when set to short pulses and moderate energy levels, can kill bacteria buried 3 mm deep in the soft tissue of the gingiva. The 1064 nm Nd:YAG laser is also effective with similar penetration depth. Both lasers spare the healthy tissue with the simulations showing minimal heating of the surrounding tissue. Minimizing the thermal damage leads to faster healing, says Reinisch.

"The findings are important because it opens up the possibility of tweaking the wavelength, power, and pulse duration to be the most effective for killing bacteria," Reinisch says. "The doctors will look at this and say, 'I see there is a possible benefit for my patients in using the laser.'"

"The study reveals what's going on in the tissue, so I hope that we're educating the medical professionals by demonstrating that you can do a good job of killing bacteria with certain lasers," says co-author David Harris, PhD, director of Bio-Medical Consultants, Inc., which specializes in medical laser product development. "When you do this treatment, you remove an infection and allow tissue to regenerate. Getting rid of the infection means the tissue can heal without interference."

The cost of dental lasers can range from $5,000 to over $100,000, according to Reinisch, and healthcare professionals require extra training to use them. These costs are passed on to the patient so Reinisch notes there must be a definite benefit for the patient to justify these costs.

Harris noted that the Academy of Laser Dentistry estimates that at least 25% of US dental offices have dental laser capability for periodontal treatment as outlined in the paper, along with a host of other soft tissue surgical procedures and hard tissue procedures like removal of dental decay.

Harris said the video simulations demonstrate what happens when lasers hit buried bacterial colonies.

"This is a great way to present to the doctor esoteric scientific findings in a clinically meaningful format," he said. "The model is a great tool for making predictions of what can happen in the tissue. Our study confirms its use as a way to determine the most effective laser parameters to use clinically."

In a first for the journal, the published results include video depictions of the computer simulations. The journal readers can actually see the soft tissue of the virtual gums and bacteria heat up and cool down as the simulated laser is scanned over the tissue.

The study's methodology of simulating how laser light interacts with tissue has implications beyond dentistry; physicians and surgeons use lasers in various treatments, including vocal cord procedures and dermatological treatments, including those for toenail fungus.

Guided by the results presented in this study, both Reinisch and Harris expect that clinical trials will be designed to validate the findings.

The study, entitled "Selective Photoantisepsis," is published in the October issue of Lasers in Surgery and Medicine.
