It is unclear whether computer-aided detection (CAD) systems for panoramic radiography can help inexperienced dentists to diagnose maxillary sinusitis. The aim of this study was to clarify whether a CAD system for panoramic radiography can contribute to improved diagnostic performance for maxillary sinusitis by inexperienced dentists.


The panoramic radiographs of 49 patients with maxillary sinusitis and 49 patients with healthy sinuses were evaluated in this study. The diagnostic performance of the CAD system was determined. Twelve inexperienced dentists and four expert oral and maxillofacial radiologists observed the total of 98 panoramic radiographs and judged the presence or absence of maxillary sinusitis, under conditions with and without support of the CAD system. The receiver-operating characteristic (ROC) curves of the two groups were compared.


The CAD system provided sensitivity of 77.6%, specificity of 69.4%, and accuracy of 73.5%. The diagnostic performance of the inexperienced dentists increased with support of the CAD system. When the inexperienced dentists diagnosed maxillary sinusitis with CAD support, the area under the curve (AUC) was significantly higher than that without CAD support. When the focus was only on panoramic radiographs in which CAD support led to a correct diagnosis, the AUC of the inexperienced dentists increased to an equivalent level to that of the experienced radiologists.


The CAD system supported the inexperienced dentists in diagnosing maxillary sinusitis on the panoramic radiographs. If the accuracy of the CAD system can be increased, the benefits of CAD support will be further enhanced.

CDC Estimate: High Periodontal Disease Prevalence Found Among Southern U.S. States

Highest Incidence Found in New Mexico, Hawaii: New Data Emphasizes Need for Oral Health Literacy, Access to Care in Largely Affected Regions

Top 10 States with
Highest Periodontitis Prevalence
New Mexico
South Carolina
*Estimated prevalence for US adults ages 30 to 79
CHICAGO (February 4, 2016)—In a recent study published by the Journal of Dental Research, the Centers for Disease Control and Prevention (CDC) estimates that at 52.79% and 51.10% respectively, New Mexico an d Hawaii have the United States’ highest prevalence of periodontal disease.

The study, entitled “Predicting Periodontitis at State and Local Levels in the United States,” also indicates high prevalence among southeastern and southwestern states, including areas along the Mississippi Delta, the U.S.-Mexico border, and among Native American reservations.
The objective of the study was to estimate the prevalence of periodontitis at state and local levels across the United States by using a novel, small-area estimation method. Extended multilevel analyses were applied among adults aged 30-79 at state, county, district, and census tract levels. 
Other areas with an estimated high prevalence were southern Florida and remote areas of western Alaska. Overall, similar geographic patterns were determined for severe periodontitis as well. The states with the lowest prevalence include Utah (37.69%) and New Hampshire (40.51%).  
Additional key statistical findings noted in the study include:
  • The prevalence of periodontitis among the states ranged from 37.7% in Utah to 52.7% in New Mexico, representing an estimated 15% disparity in prevalence among states.
    • Severe periodontitis ranged from 6.4% in New Hampshire to 11.3% in Louisiana among the states.
  • County estimates ranged from 33.7% to 68%, representing a much larger disparity of 34% in prevalence among counties.
    • Severe periodontitis ranged from 5.2% to 17.9% among counties.
  • National estimates had a mean and median state prevalence of 45.1% and 44.9%, respectively, and 46.6% and 45.9%, respectively, for counties.
    • These summary measures compare with the estimated national prevalence of periodontitis among U.S. adults of 44.8% from NHANES 2009-2012.
    • Similarly, summary measures for severe periodontitis at state and county levels compared with the estimated national prevalence of severe periodontitis.
The areas estimated to have the greatest concentration of periodontitis directly correlate with regions that also see high incidence of cardiovascular disease and diabetes, systemic conditions often associated with periodontitis. Moreover, the latest findings are in line with early CDC reports that periodontitis disproportionately affects ethnic minorities, tobacco users, those of lower socio-economic status, and those in areas with sparse access to dental care.
“This is the first study to model the distribution of adult periodontitis in states and local areas in the United States,” says Dr. Paul Eke, CDC epidemiologist and lead author of the study. Dr. Eke goes on to say, “We found the estimated geographic distribution of adult periodontitis to be highest among southeastern and southwestern states, with concentrated pockets along the southeast, in the Mississippi Delta, along the U.S.-Mexico border, and among Native American reservations. Given how closely associated the risk for periodontitis is with other chronic conditions, such as diabetes or cardiovascular disease, the prevention and treatment of periodontitis represents an opportunity for dental and medical professionals to work together to improve the public’s health.”

The figures are the latest reported by the CDC to determine the burden on periodontitis on the U.S. adult population. The American Academy of Periodontology (AAP) and the CDC, which have collaborated since 2003 to determine periodontitis prevalence, have found that nearly half of all U.S. adults age 30 and above have some form of periodontal disease.

“Periodontal disease continues to be a major health concern for people of all backgrounds,” remarked Dr. Wayne Aldredge, president of the AAP. “The AAP is committed to increasing public awareness of periodontal health and will continue to work with allied dental organizations, educational institutions, and government agencies to reduce incidence of periodontitis in the U.S. adult population.”
The AAP recommends regular flossing, brushing twice a day, and undergoing yearly comprehensive periodontal evaluations for the prevention of periodontal disease, which is treatable and often reversible with proper and timely care from a periodontist. “Individuals who suspect they may have gum disease should schedule an appointment with a general dentist in their area,” continued Dr. Aldredge. “General dentists can provide a referral to a nearby periodontist if disease is present.”

Hu-Friedy Introduces New Cleaning Monitors


Easy to Use Strips Verify the Cleaning Process for Optimal Infection Prevention

CHICAGO (Feb. 2, 2016) – Hu-Friedy, a global leader in the manufacturing of dental instruments and products, today introduced their new Cleaning Monitors, the latest addition to its Instrument Management System (IMS) Cleaning & Care Product Line. 
Designed for monitoring the efficiency of the cleaning process when using washer-disinfectors and ultrasonic cleaners, the Cleaning Monitor system consists of equipment specific monitor strips and a reusable holder. The monitor strips contain a test soil that mimics the presence of blood and tissue that may be found on an instrument surface after its use. Full removal the test soil from the strip indicates an effective cleaning process.
Proper cleaning is the first step to effective instrument reprocessing; if debris is not removed, the instrument surface cannot be effectively sterilized. The current accepted standard for the degree of the cleanliness of instruments is “visibly clean”, however, not all components of blood and tissue are easily visible. Used on a daily or per-load basis, Hu-Friedy Cleaning Monitors give insight into the effectiveness of the cleaning process. 
Monitoring and verifying the cleaning process are important elements of quality assurance, and advisory bodies recommend that cleaning processes be continually modified to add new safeguards.
“With more than 30 years of experience delivering infection prevention solutions to our customers, Hu-Friedy understands the importance of the first step in instrument reprocessing,” says Ken Serota, President of Hu-Friedy Mfg. Co. “Our easy to use and easy to interpret Cleaning Monitors offer a cost-effective way for clinicians to monitor the cleaning process to ensure they are providing the highest level of care to their patients.”
The equipment-specific Cleaning Monitor strips are available in packs of 50 for both washers and ultrasonic cleaners. Visit  for more information.

LED Medical Diagnostics Announces Successful Results for Latest Clinical Research Using VELscope® Tissue Fluorescence Technology

Study Shows the Use of a VELscope When Determining Surgical Margins for Excision of Early-Stage Oral Cancer Leads to Significant Reduction of Local Recurrence
Vancouver, British Columbia, January 26, 2016 - LED Medical Diagnostics Inc. ("LED" or the "Company") (TSX-V: LMD) is pleased to announce that the results of a study, titled "Fluorescence Visualization-Guided Surgery for Early-Stage Oral Cancer," have been published in the Journal of the American Medical Association - Otolaryngology - Head and Neck Surgery. The publication reports the findings of a retrospective, case-control observational study that was conducted on 246 patients from September 1, 2004, to August 31, 2009. The study showed a significant reduction in the rate of local recurrence of early-stage squamous cell carcinoma and high-grade precancerous lesions in patients where VELscope tissue fluorescence visualization was used to assist in determining the surgical margin for excision, compared to those patients where conventional methods were used. "This is really a revolutionary way for surgeons to visualize a diseased region," stated Dr. Catherine Poh, principal investigator and Provincial Oral Medicine Leader for Oral Oncology at the BC Cancer Agency. "We are now working with head and neck surgeons across Canada to conduct a multi-center trial that will convince the world to change practice and improve the treatment of oral cancer." "The results of this important clinical study will be of great interest to oral cancer patients and practitioners alike," commented Dr. David Gane, CEO of LED.  "It adds to the growing body of peer reviewed literature that corroborates the use VELscope as an effective adjunct in oral cancer treatment, while further supporting its use in concert with a comprehensive oral examination to screen for the presence of oral cancers and pre cancers." "Fluorescence Visualization-Guided Surgery for Early Stage Oral Cancer" has been published online in the Journal of the American Medical Association – Otolaryngology – Head and Neck Surgery (JAMA Otolaryngology Head Neck Surg.

About Dr. Catherine Poh Dr. Catherine Poh is an associate professor in the Faculty of Dentistry at the University of British Columbia, a clinician scientist at the BC Cancer Agency, and an oral pathologist and researcher at the Vancouver Coastal Health Research Institute. She is also a Canadian Institutes of Health Research clinician scientist and a Michael Smith Foundation for Health Research Scholar. Dr. Poh is also one of two practicing oral maxillofacial pathologists in British Columbia, Canada, and an active staff member of the Oral Oncology Department of the BC Cancer Agency as well as the Oral Mucosal Disease Program at Vancouver General Hospital.  Her primary research focus involves application of molecular and imaging tools for community screening, early detection, and management of cancerous and precancerous oral lesions.  

About VELscope® Vx Enhanced Oral Assessment The distinctive blue-spectrum light of the VELscope Vx Enhanced Oral Assessment System causes the soft tissues of the mouth to naturally fluoresce. Healthy tissues fluoresce in distinct patterns that are visibly disrupted by trauma or disease, such as neoplastic lesions, chemical irritation, and side effects from medication, thermal damage, and fungal, viral or bacterial infections. Use of the VELscope Vx handheld adjunctive device allows a wide variety of oral abnormalities to be discovered, often before they become apparent to the unassisted eye. It is also the only tissue fluorescence device with photo/video documentation capabilities through the viewing mechanism, a key function for referrals and patient records. There are more than 40,000 new cases of oral cancer diagnosed in the United States alone every year and early detection is critical for survival; when detected early, the five-year survival rate rises from less than 50% to more than 80%. VELscope systems are used during more examinations for oral cancer and other oral diseases than any other adjunctive device. For more information, visit
