NPR reported the age old noise of knuckle cracking does not cause arthritis, and may actually be good for the joint. According to Dr. Kevin deWeber of Vancouver, Canada, the arthritis urban myth is a misconception perpetuated by “by mothers who are sick of hearing their kids crack their knuckles.” Dr. Greg Kawchuk, professor of Rehabilitative Medicine at the University of Alberta performed a MRI study discerning the culprit behind the noise:gas bubbles which get collapsed upon the knuckle cracking.
So what about other joints? Many dental patients complain of jaw joint noises. The implication of Dr. Kawchuck’s study is that the noise is harmless and moving the jaw around to create the pop may actually help. This still has to be verified by dental research. Pain, on the other hand, is a complicating factor which would need to be investigated by your doctor. Popping the joint may be harmful in those cases. Stick with the knuckles!
Stem cells hold promise to regenerate many different body tissues. Until recently, stem cells were difficult to procure. Several years ago it was discovered stem cells are present in many body tissues, particularly the teeth. Extracted teeth can have stem cells harvested and banked so that in the future, if needed, the cells are there for you. The ADA announced in the march 2, 2015 News that research at the University of Pittsburgh have been able to coax dental stem cells into corneal (eye) tissue, and could one day be used to repair corneal injuries. Presently, Store-A-Tooth offers the ability to save your stem cells from extracted teeth. Your future could depend up on it! For more information call us at 973-379-2730.
Mailonline ran an article with the title, “Mouthwash use “linked to oral cancer”: People who use products more than three times a day increase risk.” The research, done by a Scottish doctor at the University of Glasgow has been deemed inconclusive by the British Dental Association. The article did however, indicate that there “may be a link between excessive mouthwash rinsing and people who use it to mask the smell of smoking and alcohol.” These alone are independent risk factor for cancer, and together exert a well established link for cancer. As such, mouthwash may not be as significant as the alcohol and smoking with regard to cancer, and should probably not be discontinued if recommended for use.
Ebola is a potentially deadly viral disease which is not treatable by medications. Estimates range from 50-90% mortality rate. Infection is believed to be possible through direct contact, and is currently not considered an airborne disease. A person is considered infectious and should be quarantined when a fever is above 101.5 F, assuming that person’s fever is related to travel to, or contact with, any of the hotspots or persons who have been to or come from the hotspots in Africa.
It is believed if a person has not exhibited any signs or symptoms after 21 days, there is no risk.
Given the nature of some of the cases around the globe, clearly not all the information is consistent. More alarming are the cases of Ebola infection in which people who are unknowingly infected may have had multiple contacts with persons who may also become infected. This seems to be the case of the emergency room doctor in Spain, who just quarantined himself. How many patients did he contact before this self imposed quarantine. In theory, if he was afebrile it should not be a concern. However, if any one of these people become infectious, the virus spread will literally “go viral.”
We are screening all patients for fever using a non-contact infrared thermometer in the interest of protecting all our patients. Even though the likelihood of contagion is very small at present, we want to be very proactive in what could prove to be a serious problem. We request any patient who has a non-allergic cough or fever to please reschedule their appointment. For now, everyone should observe simple precautions: wash hands thoroughly after contact with strangers or foreign objects. Avoid high risk persons, e.g. people who have just come back from one of the African hotspots (after 21 days such persons are thought to be noninfected). But, if you have reason to suspect you have been infected, seek immediate Hospital care!
From the Amereican Dental Association ( ADA):
Good Morning America Segment on Microbeads in Toothpaste
ABC’s Good Morning America (GMA) contacted the ADA for a segment that aired today on microbeads (polyethylene) in toothpaste. All of the varieties of Crest ProHealth® toothpaste which have earned the ADA Seal of Acceptance contain microbeads.
The ADA provided a press statement to the GMA producer indicating, “According to the American Dental Association, clinically relevant dental health studies do not indicate that the ADA Seal should be removed from toothpastes that contain polyethylene microbeads. Products with the ADA Seal have been independently evaluated for safety and effectiveness by the ADA Council on Scientific Affairs.”
Local news stations, including ABC 7 Chicago, have previously reported on microbeads from health and environmental angles. Procter & Gamble (P&G), the manufacturer of Crest ProHealth®, includes information for the public on their website and has indicated they plan to remove microbeads from toothpaste.
According to P&G, “While the ingredient in question is completely safe, approved for use in foods by the FDA and part of an enjoyable brushing experience for millions of consumers with no issues, we understand there is a growing preference for us to remove this ingredient. So we will. Crest will continue to provide consumers with effective and enjoyable products which are designed to their preferences.”
The following suggested talking points may help you discuss the issue with your patients should they ask you about microbeads in toothpaste:
- Microbeads have been in the news lately. You may have heard about it in connection with toothpaste.
- Microbeads are most often used as scrubbing beads in exfoliating skin care products.
- The FDA has approved microbeads as a food additive, and small quantities, which appear as colored specks, are in some of Crest’s toothpastes, including Crest Pro Health, which has the American Dental Association Seal of Acceptance.
- According to the ADA, clinically relevant dental health studies do not indicate that the ADA Seal should be removed from toothpastes that contain microbeads.
- Products with the ADA Seal have been independently evaluated for safety and effectiveness by the ADA Council on Scientific Affairs.
- While there is no clinical evidence that microbeads in toothpaste are harmful to your dental health, Crest is voluntarily withdrawing the ingredient from toothpaste in response to growing consumer preference.
- As your dentist, my goal is to help you achieve optimal dental oral health. Whenever you have questions about any dental care product, feel free to talk with me.
- Brushing two minutes twice a day with fluoride toothpaste and flossing daily are important ways to take care of your dental health.
Some concerns have been raised about the safety of triclosan, an ingredient in Colgate Total toothpaste. At present it is believed to be safe in the amounts used, though the EPA is looking into data concerning the endocrine effects, developmental and reproductive toxicity, chronic toxicity and carcinogenicity. There are also concerns about the possibility of Triclosan contributing to making bacteria resistant to other bacteria.
Triclosan has been shown to be effective in preventing gingivitis. Colgate’s website refutes some of the research claims about carcinogenicity and endocrine effects, and offers the extensive research which supports the use of Triclosan in toothpaste. It remains to be seen then, whether further research will continue to vindicate its use in toothpaste.
This information comes from the United States Environmental Prtoection Agency factsheet on Triclosan, the the U.S. Food and Drug Adminstration Factsheet, and Colgates’s website.
Very few communities in New Jersey have water fluoridation. As such, the benefits of fluoride for the prevention of tooth decay must be obtained through other means. For children, this is in the form of an ingestible source, typically a vitamin with fluoride added, or simple fluoride drops. To avoid excess fluoride consumption the following recommendations have been made. It breaks down into three columns of possible external sources of fluoride consumption, such as bottled water, or areas where fluoride occurs naturally in drinking water.
||<0.3 ppm other sources of fluroide
||0.3-0.6 ppm other sources of fluroide
||>0.6 ppm other source of fluoride
|Birth to 6 Months
|6 months to 3 years
|3 to 6 years
|6 to 16 years
It should be noted iingestible fluoride is only of benefit when the teeth are being formed and the fluoride can become incorporated within the enamel . After teeth have erupted, ingestible fluoride is of no use, and only topical applications of fluoride are of benefit, such as toothpaste and/or fluoride applications or rinses.
Back in 1992 I attended a lecture which convinced me to stop using amalgams, the mercury-silver fillings that look black in people’s mouths. Besides the obvious concern of mercury toxicity to both patients and myself, was the fact amalgams weaken the tooth and set it up for fracture. Tooth colored bondings, on the other hand, help hold the tooth together, and have the obvious esthetic advantage. While the American Dental Association maintains dental amalgams are safe, several European countries have outlawed them. It should be stressed however, there is no proof that having the amalgams removed will improve any ailments. While it is true mercury is toxic, there are no conclusive studies that link the mercury in dental amalgams to any specific diseases. That being said, we still chose to stop placing the silver-mercury fillings and offer the better alternatives instead. Our patients are happier, and so are we!
No doubt given enough time researchers will find everything we love to eat is no good for you. The latest research on French Fries has touched off a panic with the discovery of Acrylamide in the fries. It seems in high amounts, acrylamide causes cancer in lab animals (reminds me of the cyclamates scare in the 80’s). Like all things, it really is a matter of amounts, and the amounts given the lab animals was in greater excess than what humans would consume. Then consider, all foods cooked at elevated temperatures have chemical changes, including the formation of acrylamide! Since man discovered fire and cooked his first mastodon burger, acrylamide was present. So, do we worry about the latest findings? At least no one has shown French fries are bad for your teeth…yet!
