Tissue fluorescence has been used as an aid in visualization of oral mucosal abnormalities, such as oral cancer and pre-cancer. Fluorescence technology has been used in the medical field for many years, and in the dental field it has successfully screened more than 25 million patients in the past decade.

Saini et al. published a paper using OralID as a screening tool in visualizing oral premalignant lesions. In a high risk population, a conventional oral exam and OralID was compared to only a conventional oral exam.

Biopsies were taken of suspicious lesions in both groups. Sensitivity and specificity both improved; 8.1% and 11.4%, respectively; when clinicians utilized the OralID.

The Conclusion from the study was: “Results from this study suggests that OralID is a true adjunct to conventional oral examination in [visualizing] potential malignant changes in subjects visiting for regular dental check-up.”

Laronde et al. describe incorporating a clinical risk assessment in combination with fluorescence to predict lesion persistence. Unsurprisingly, " [t]he most predictive model for lesion persistence included both [fluorescence] status and lesion risk assessment."

"A protocol for screening (assess risk, reassess, and refer) is recommended for the screening of abnormal intraoral lesions. Integrating [fluorescence] into a process of assessing and reassessing lesions significantly improved this model."

"For those clinicians in general practice without the experience and expertise of a specialist, an imaging device to aid in the decision to refer would be very helpful. At the community level, the critical decision is not whether or not the lesion is cancer but whether or not the lesion should be referred for further investigation. Reassessment at a 3-week follow-up appointment is critical to improving the specificity of the FV autofluorescence imaging device."

This scientific article from the International Journal of Biomedical and Advanced Research explains why oral cancer screening in the dental set up is important. Below are a few statements taken from the journal article:

“…light-tissue interactions can be exploited to improve the visualization of neoplastic lesions.In particular, tissue autofluorescence has recently shown promise as an adjunctive diagnostic tool."

“Oral cancer and pre cancer display a loss of autofluorescence across a broad range of UV and visible excitation wavelengths."

“The incorporation of OralID in the first-line practice settings, such as dental offices and primary health care settings, may be a boon to population for regular check up for pre malignant lesions.”

“There is an enormous amount of advantage of this cost effective device (OralID) in the developing countries where financial liability is the main hindrance during oral cancer screening for the mass population."

Supersaturated Calcium phosphate rinses are well studied and have been proven effective in treating dry mouth, xerostomia, and mucositis. Below is just a sampling of the available literature.

Saini reports on the results of SalivaMAX in a xerostomic population (n = 38) with high levels of S. mutans. Compared against a control using standard customary treatment, the SalivaMAX group (customary treatment plus SalivaMAX 4x/day) had a statistical (p<0.05) and marked improvement in oral hygiene scores and other measured outcomes.

Brock et al. describes the use of SalivaMAX, a supersaturated calcium phosphate rinse, by head and neck patients receiving 70Gy of fractionated IMRT chemoradiation as compared to the standard of care, a salt/soda rinse. The SalivaMAX group demonstrated a significant reduction in the peak level of mucositis along with a delay in the onset of mucositis during treatment as compared to the control. More specifically, using assessments based on the WHO Oral Mucositis Scale 90% of SalivaMAX patients were eating solid foods with many not even experiencing ulcerations. While in the control group, 40% of the patients were on a liquid diet.

This study provided a review of thirty studies and found that the majority (24) reported that a supersaturated calcium phosphate rinse was efficacious at reducing the mucositis grade and/or duration as well as the mucositic pain associated with the condition.

• mucositis duration
• oral toxicity severity (WHO scale)

• PEG tube application
• In-patient hospitalization
• Incremental costs of treatment for oral mucositis (savings of $1,700 - $7,000 per person)

This is a first published study to determine the efficacy of a supersaturated calcium phosphate oral rinse on patients with solid tumors (breast cancer) in response to chemotherapy-induced mucositis. Although this was a single sided study, the short time to elimination of mucositis was noteworthy: resolution of Grade 3 mucositis was an average of 4 days and Grade 2, 3.5 days.

This study by Taylor evaluated the cost benefit of using a supersaturated calcium phosphate rinse for treating oral mucositis in patients undergoing conditioning therapy for bone marrow transplantation (high dose chemo) and head and neck cancer (chemo and radiation therapy). The net savings of using a supersaturated calcium phosphate rinse over the standard of care were $5,582 and ranging $475 - $6,695, respectively, for each patient in addition to the positive clinical outcomes.

This peer reviewed paper by Levin offers a general approach to the etiology, diagnosis and management of xerostomia.

• draws a distinction between organic and non-organic components of saliva
• highlights that most xerostomia in a general dental setting is caused by medications
• identifies supersaturated calcium phosphate rinse as one of the most powerful adjuncts in the care of xerostomia
