VELscope in Oral Cancer Screening

VELscope in Oral Cancer Screening

Phoenix Dentist, Dr. Alan Ferguson uses the newest technology in screening for oral cancer, VELscope.  VELscope, a handheld device used by emits a harmless, bright blue light which is used to inspect the mouth and tongue. The device is extremely sensitive to abnormal tissue changes and the distinctive blue-spectrum light 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, and fungal, viral or bacterial infections.

Dr. Ferguson uses the VELscope device to supplement his regular comprehensive oral exam (intra and extra oral head and neck exam) to help identify potential cancerous or pre-cancerous tissues that cannot be identified with the naked eye.

When discovered early the 5-year survival rate for oral cancer patients is about 83%. Unfortunately, most cases of oral cancer are discovered in late stages, when the five-year survival rate drops to around 50 percent.  These statistics prove the importance of utilizing the VELscope technology and identifying oral cancer in its early stages.

Dental Science Experiment for Kids - Does Fluoride Strengthen Teeth?

Items Needed:

• Two hard-boiled eggs 
• Fluoride gel or solution, 4 oz to 6 oz
• Three clean plastic containers
• Several cans of dark soda
• Water

Experiment:

1) Place a hard-boiled egg in one of the plastic containers and cover it with the fluoride gel or solution. Let the egg soak in the fluoride for twenty-four hours. Remove the egg and rinse it with water. 

2) Place this “treated” egg in one of the two remaining clean containers, and place the “untreated” egg in the other. 

3) Cover both eggs with dark soda. Change the solution every 12 hours for two days. 

What was your Conclusion?

Results of the Experiment:

The “untreated” egg will begin to dissolve slightly, and the shell will become stained by the dark soda. 

The “treated” egg should not show a reaction until much later. The conclusion could be drawn that the use of fluoride helps strengthen teeth and protect them from decay. 

The Consequences of Missing Teeth

There are several negative consequences of missing some or all of your teeth. First, missing teeth will affect the aesthetics of your face. Not only will your smile be affected by the gaps from missing teeth, but if you’re missing too many teeth, the skin around your mouth won’t be supported properly and will start to sag, making your appear older than you are. Additionally, missing teeth will make it more difficult to chew your food properly and may even affect the way you speak. Finally, missing even one tooth may have emotional consequences; many people feel less confident about their smile when they are missing teeth. If you are currently missing any of your teeth, consider replacing them with dental implants, which can look and feel just like natural teeth.  

If you have missing teeth and are unsatisfied with the look of your smile, contact Dr. Alan Ferguson's office at (602) 242-5445 to schedule an oral evaluation.

Should You Share Your Toothbrush with your Partner/Spouse?

Just because you kiss your partner/spouse, sleep with them or occasionally taste food off their fork, these are not reasonable justifications for using their toothbrush.

Brushing your teeth sometimes causes the gums to bleed, which exposes everyone you share your toothbrush with to blood stream diseases. Therefore, by sharing a toothbrush, the couples are actually sharing blood, which is a lot more risky than just sharing saliva. 

By using their toothbrush, you automatically introduce millions of their oral bacteria into your mouth and likewise leaving undesirable bacteria on the brush for them.  Dental decay is caused by bacteria called streptococcus mutans and is contagious.

Other diseases a person risks contracting when he or she shares a toothbrush with another are cold sores, herpes, fungus and periodontal disease.

Soft Tissue Diode Laser Treatment

One of the most effective tools our dental hygiene team has incorporated is the use of the soft tissue diode laser. During a 2-4 minute laser bacterial reduction, the bacterial count can be reduced from “millions” of bacteria to “hundreds”. This allows for quick profound healing of inflammation. It reduces the amount of bacteria that can enter the blood stream and travel to the brain, heart, liver, etc. The laser is also used during scaling and root planning treatment of periodontal disease.

Top 5 Teeth Staining Culprits!

Culprit #1

Coffee and Tea. Many of us love a good old cup of Joe in the morning or a nice cup of tea. Unfortunately, drinking several cups per day will cause the tannin chemicals in coffee and tea to turn your teeth yellowish or a darker shade. If you must have that coffee or teas in the morning to get going, try to limit your intake to a cup per day. Avoid black coffee or tea - try milk-based choices if at all possible.


Culprit #2
Cigarettes. One of the worst offenders, cigarettes stain you teeth in multiple ways... not only do the effect of the tobacco leaves stain your teeth, the habit of smoking causes the smoker to continually expose the teeth to the staining process.


Culprit #3
Wine. Dark wines such as reds have the greatest staining impact on your teeth due to the dark purple colors found naturally in the grapes used for their production. Lighter wines have a lesser impact, but can still stain your teeth over time. Always try to rinse your mouth thoroughly with clear water after enjoying wine to minimize the staining impact of your vino.


Culprit #4
Soda / Pop / Cola. Whatever you call them, dark colored soft drinks can have a major staining effect on your teeth. The food coloring in soda heads right to the tooth and begins darkening almost immediately. If possible, limit your intake of soda, or enjoy lighter colored sodas. Using a straw to sip you soda can also help reduce the staining effect by reducing the contact between the soda and your teeth.


Culprit #5
Processed foods. Make processed foods are chocked full of chemicals and food colorants that make them look and taste mouth-wateringly yummy. Unfortunately, those artificial goodies are a big source of teeth staining badness. Don't believe us? Have a quick peek at your teeth after enjoying some chips or another snack. They'll most likely resemble the snack instead of their normal bright white selves.

Tooth Enamel May Be Damaged By Early Exposure To Bisphenol A

Are teeth the latest victims of bisphenol A? Yes, according to the conclusions of work carried out by the research team led by Ariane Berdal of the Universite Paris-Diderot and Sylvie Babajko, Research Director at Inserm Unit 872 "Centre des Cordeliers". The researchers have shown that the teeth of rats treated with low daily doses of BPA could be damaged by this. Analysis of the damage shows numerous characteristics that are common with a recently identified pathology of tooth enamel that affects roughly 18% of children between the ages of 6 and 8.

These results have been published in the American Journal of Pathology.

Bisphenol A (BPA) is a chemical compound used in the composition of plastics and resins. It is used for example to manufacture food containers such as bottles or babies' bottles. It is also used for the protective films inside drinks cans and food tins, or as developers on sales receipts. Significant amounts of BPA have also been found in human blood, urine, amniotic liquid and placentas. Recent studies have shown that this industrial compound has adverse effects on the reproduction, development and metabolism of laboratory animals. It is strongly suspected of having the same effects on humans.

As a precautionary measure, the manufacture and commercialisation of babies' bottles containing bisphenol A were prohibited in Europe in January 2011. The prohibition will be extended to all food containers in France as from July 2015.

So this study shows that teeth are the latest in an already long list of victims of BPA.

The Inserm researchers have shown that the incisors of rats treated with low daily doses of BPA (5 microgrammes/kg/day) could be damaged by this. This effect has also been observed within a development window of no more than 30 days post-birth in rats, thus demonstrating a range of sensitivity to exposure.

Analysis of these teeth showed numerous characteristics that are common with a tooth enamel pathology known as MIH (Molar Incisor Hypomineralisation) that selectively affects first molars and permanent incisors. This enamel pathology is found in roughly 18% of children between the ages of 6 and 8. Children affected by this pathology present with teeth that are hypersensitive to pain and liable to cavities. It is interesting to note that the period during which these teeth are formed (the first years of life) correspond to the period during which humans are most sensitive to bisphenol A.

Amongst the earliest observations made was the appearance of "white marks" on the incisors of rats treated with endocrine disruptors, one of which was bisphenol A (BPA). The researchers decided to define the characteristics of incisors of rats treated with low doses of BPA and to compare these with the characteristics of teeth in humans suffering from MIH

Macroscopic observation of marks on both series of teeth showed similarities, in particular fragile and brittle enamel.

Microscope observation of the enamel showed a significant reduction of the Ca/P and the Ca/C ratios in affected teeth. This leads to mineral depletion, making the teeth more fragile and more liable to cavities.

Finally, analysis of the proteins present in the tooth matrix of rats showed an increased quantity of enamelin, a key protein for enamel formation, and a buildup of albumin leading to hypomineralisation. Analysis of the expression of key enamel genes highlighted two BPA target genes: enamelin and kallicrein 4.

According to Sylvie Babajko, the latest author of this article, "Insofar as BPA has the same mechanism of action in rats as in men, it could also be a causal agent of MIH. Therefore, teeth could be used as early markers of exposure to endocrine disruptors acting in the same way as BPA and so could help in early detection of serious pathologies that would otherwise have occurred several years later".

Services Provided

X-rays

X-rays allow us to see in between the teeth and under existing fillings to help us detect tooth decay. X-rays can also help us check the health of the bone supporting the teeth.

Diagnostic Impressions

Diagnostic impressions are taken to ensure the fit of any crown, bridge, or denture. The exact shape of your teeth and gums is molded in a flexible vinyl mixture that sets quickly. The vinyl mold is then used to create a replica of your mouth with plaster or plastic.

Comprehensive Oral Exams

The first step in any dental care plan is to determine your existing health conditions. If you are a first-time patient, we will perform a comprehensive examination; including recording of your medical history, taking full x-rays, screening for oral cancer, examining periodontal (gum) condition, checking each tooth for cavities, and examining your jaw and bite.

Periodic Oral Exams

As an established patient with a preventive dental care plan, you will come to the office on a regular recall schedule for a cleaning and check-up. Periodic exams are important for maintaining your healthy smile.

Consultation and Treatment Planning

Oral health is a lifelong concern. We will help you understand any conditions that need treatment and devise a plan for correcting them. We will also discuss the options for any cosmetic treatments you may be interested in. Furthermore, we will outline a regular course of preventive care.

Cracked Tooth Syndrome

Cracked tooth syndrome, as the name suggests, is the development of cracks and fissures in teeth over time. These cracks may be invisible to the naked eye but extend deep into the tooth. We examine your teeth for cracks so that we can take preventive action before the tooth suffers severe damage.

Gum Disease Diagnosis

Gum disease is much more common than people think. We will examine your gums for disease and make recommendations based on your specific dental healthcare needs. Regular, careful brushing and flossing are essential to gum health.

Oral Cancer Screening

Currently oral cancer is on the rise in a much younger population; all individuals are at risk for developing oral cancer.  What used to be related to smoking and chewing tobacco is now being linked to very common viruses, making oral cancer a much greater concern for a larger population.  We pride ourselves that each and every patient seen in our practice is given a visual oral cancer screening and we have additional technology called the Velscope® which allows us to catch even the earliest of lesions.
