Given this widespread interest, a vast range of products is now available on the market in various forms, from gels to self-adhesive strips, kits with trays, chewing gum and mouthwash. The term "whitening" refers to any process intended to brighten teeth. Two types of products are used for this purpose. First, there are bleaching products that actually alter the colour of the tooth enamel by means of peroxide, a product that can reduce deep and surface stains.
Then there are whitening products that do not change the colour of the enamel, but simply remove surface stains. There are two main types of bleaching products: those with a high concentration of peroxide, used under a light or laser in a dentist's office, and products distributed by dentists or sold over the counter, for use at home. The most common side effects associated with bleaching products are temporary tooth sensitivity and occasional irritation of soft tissues. In some exceptional cases, teeth have been irreversibly damaged.
Whitening products, including toothpaste, chewing gum and mouthwash, contain abrasives or chemicals to improve tooth appearance.
They reduce surface stains using light polishing or other actions that do not alter tooth colour. Tooth bleaching using colour-altering products is a safe therapeutic choice, when carried out under a dentist's supervision and according to the manufacturer's recommendations.
It may not be suitable for everyone, however. The Ordre des dentistes du Québec recommends that patients, especially those with many fillings or crowns or heavy staining, consult their dentist to decide on the treatment that best suits them. The Order also suggests that pregnant women delay bleaching treatment until after they have given birth.
Children under age 12 should not use bleaching products.

The requirements are as follows. We consider it important to point out that some dentists may be using amalgam separators that do not comply with the by-law, since some equipment suppliers have not yet been able to produce proof of certification. The city of Montréal considers their equipment to be non-compliant. The city wishes to remind dentists that the operator of a dental office, and not the equipment supplier, is solely responsible for applying the by-laws in effect on the Island of Montréal.

Dental offices produce a certain amount of waste every day, including hazardous waste that can harm the environment if it is not managed properly. ODQ's Executive Committee adopted a resolution on best management practices for dental waste, with a view to protecting the environment. The goal is to limit and if possible eliminate environmental pollution owing to dental waste produced by dental offices in Quebec.
In doing so, the Order is endorsing the position statement adopted by Health Canada and supported by the Canadian Dental Association. The Order also recommends that the professional inspection protocol be amended so as to make Quebec dentists aware of applicable regulations and proper management of hazardous waste from dental offices.
Environment Canada has produced an electronic guide entitled Dental Wastes: Best Management Practices, which can be consulted at www. The purpose of the guide is to inform dental professionals on how to manage hazardous waste so as to minimize the release of toxic substances into the environment. The guide contains useful information on managing waste, pollution-prevention tips tailored to dental practices and details on waste-management regulations and legislation applicable to dental professionals.

The Ordre des dentistes du Québec salutes the decision by the Direction de santé publique DSP to launch a campaign to fluoridate drinking water for half the population of Quebec over the next five years. This promising initiative reflects the importance for the DSP of the benefits linked to fluoridation for Quebecers.
The Ordre des dentistes du Québec, along with such international and national organizations as the World Health Organization and the Canadian Dental Association, unreservedly supports the fluoridation of drinking water, given its positive impact on dental health.
The Ordre des dentistes du Québec supports the judicious use of fluoride with a view to preventing dental caries, including the fluoridation of drinking water. Fluoride acts in several ways to prevent and slow the development of caries. It prevents the demineralization of tooth enamel and encourages remineralization.
The pre-eruptive systemic effect occurs while teeth are forming and maturing. Fluoride is incorporated into the tooth enamel and dentine at that point and makes them more resistant to caries. The post-eruptive systemic effect is the topical action of the fluoride excreted in oral fluids after ingestion. The fluoride contained in most toothpaste, some brands of mouthwash and professional applications by dentists also has a topical action on teeth. Along with the World Health Organization, the Canadian Dental Association and Quebec public health authorities, the Ordre des dentistes du Québec considers that water fluoridation is an effective, safe and inexpensive public health tool for reducing dental caries among people of all ages.
