Teeth whitening is an ever increasing procedure being requested by many patients. In this paper, I will be discussing the biological and chemical mechanisms of teeth whitening, the difference between in office and take home whitening, current products on the market, and current issues and safety concerns regarding teeth whitening. Knowledge of these topics is important to have to be able to safely recommend in office or at home whitening options. Color can be viewed based on three different dimensions. The Munsell color system classifies colors based on hue, value, and chroma. Hue describes the color family or underlying tone (e.g., green, blue, red). Value describes the brightness or darkness on the scale on zero to ten, zero being white and ten being black. Chroma describes the saturation or vividness of a color. The appearance of teeth is affected in three ways by whitening. First, whitening reduces the amount of chroma in the tooth—the pigment or intensity of color is reduced. Second, whitening changes the hue, or color, or the teeth. Thirdly, whitening changed the value of the teeth. It is important to understand the natural color of teeth. Individual teeth vary in color in their thirds. The incisal third is usually the lightest because it is composed of mostly translucent enamel. The middle third is the next darkest and is closer to the color of dentin, but is modified by the translucent enamel that covers it. The cervical third in the darkest portion of the tooth because enamel in thinnest in this region, and the color of dentin is more visible. When looking at the smile as a whole, the shade of individual teeth varies between each other. The maxillary centrals are usually the lightest teeth and have a higher value.

It is recommended that clinicians delay the placement of bonded restorations until 1-3 weeks after treatment (Can-Karabulut et al 2011). Since whitening agents produce free radicals, some people may question the carcinogenicity of those products. A literature review conducted by Munro et al in 2006 looked at more than 100 clinical studies. Results showed that there is no date to show that hydrogen peroxide poses a carcinogenic risk to human oral mucosa at the exposure levels associated with tooth whitening. Mice models did show that hydrogen peroxide at high levels is genotoxic and carcinogenic, but humans posses more catalase activity than animals. Also, hydrogen peroxide concentrations were found to be highest in the gingiva, but this is a site where oral cancer is rarely found.
Have you ever wondered, “What are my drinks doing to my teeth?” Well, you will find out through our experiment. This means taking teeth and putting each one in a liquid and observing them over a period of time. What we did was we took six teeth and put them in six different sugary liquids. The effects will be big. This won’t happen to you if you don’t brush your teeth.
In White Teeth, Zadie Smith warns against the dangers of purism and letting cultural background completely shape one’s identity while simultaneously paying tribute to the rich heritage and beliefs of her characters. It is a cautionary tale for immigrants but is never dismissive of their past. Smith is merely advising against tunnel vision and stressing the need to adapt to one’s environment. She shows the beauty that can stem from adaptation while warning that an inability to do so will lead to one’s downfall. London plays an especially important role as the battleground where the past and the present clash; a melting pot with a large immigrant population and inevitable moral struggle.
It is regarded as a great challenge to be achieved in adhesive dentistry. The root dentin differ from the coronal dentin, thus the bonding will be different. The achievement of good infiltration and micromechanical retention remain a challenge because of limited access and vision, regional variation in bond strength, presence of a thick smear layer. The bond strength differs along the root canal and it is lower than coronal dentin.
Dentistry as a profession over the years has evolved rapidly in light of new scientific evidence. Rapidly evolving science and technology have implemented changes within dentistry as evidenced by new standards and guidelines being produced by nationally recognised associations including National Institute for Health and Clinical Excellence (NICE), Faculty of General Dental Practice (FGDP) and Scottish Intercollegiate Guidelines Network (SIGN) in Scotland, in provision of new scientific evidence. The latest standards and guidelines produced, endorse everyday clinical practice through evidence based dentistry (REF). All dental professionals as part of continued professional development are expected to keep to date on relevant guidelines and knowledge related to their practice (REF). This is supported by the General Dental Council who state all clinicians must maintain their professional knowledge and competence throughout their working career (REF).
Healthcare is a necessity to sustain society. Dentistry is an area of healthcare that I feel extremely passionate about because access to proper dental care is limited, especially in the underserved communities. As an African American, I want to become a dentist and healthcare provider in the hopes of helping patients and adding to the diversification of the field. With a growing minority population in the United States, it has become apparent that there is a shortage of black dentists. This is problematic because underrepresented minorities are in great need of access to culturally connected dentists who understand their clinical needs as much as their lives and their challenges. I believe that when the profession includes a range of ethnicities
my drinks I wanted to test. I hypothesized that Coke will stain teeth most, because not only is

Introduction: In Canada, general dental health is not part Canada’s national system of health insurance (Medicare) (1) except for some dental surgical procedures that are performed at hospitals. Since Oral health does not come under the Health Act about ninety-five percent of the oral health care services are offered on a fee-for-service basis. Oral health care is under provincial or territorial jurisdiction like other health care services and publically financed dental care programs provide the remaining five percent of oral health care services (2). Thus, majority of Canadians receive oral health via privately owned dental clinics. Privately owned dental care gives these services providers control over dental service charges, types of available treatment for the patients and number of follow-up appointment for treatments or routine care. Service users pay for the dental expenses from their own pockets or utilize insurance coverage (1).
Dental hygiene is a dynamic and challenging career that offers team work, personal growth, and extraordinary benefits, and it is the perfect career for me. As a health care professional, the dental hygienist is an important member of the dental team providing patient care. Good qualities for a dental hygienist are compassion and enjoying talking to people which are two qualities that fit my personality. I love the thought of knowing I made a positive impact in a person's health. Becoming a dental hygienist professionally requires you to obtain an associate degree in dental hygiene. They affect the average American by educating them about dental care. A dentist helps people with their dental health, which can greatly impact a person’s day-to-day life.
The book “White Teeth” by Zadie Smith had a multitude of recurring themes throughout the book from friendship and identity to social classes and religion. The novel first started off with the year 1975 New Years day and the protagonist, Archie Jones, a light-skilled Englishman, is trying to kill himself in his car after his divorce with his wife but failed to do so. Wandering around later that day not knowing where to go and what to do being led to an “End of the World” party meeting his soon to be wife there. Stumbling into this party was his belief that life had a plan for him to turn his life around and to live a new life. Early in the morning after all the drunk have passed out on the floor of the kitchen a few people are still left awake.
In order to find articles and/ or guidelines related to this issue I used Pubmed. Some of the keywords used during this search were carbide peroxide, eldery, tray bleaching, and teeth discoloration.

Whitening your teeth is a simple cosmetic, non-invasive procedure that lightens the natural colour of your teeth, resulting in a whiter, brighter smile.
A nice smile makes you look great and helps maintain optimal health. Luckily, regular brushing with your favorite toothpaste, along with regular dentistry, will keep your teeth whiter and healthier. One thing for young adults to be aware of is that you have some new teeth coming! Your wisdom teeth are the last of your 32 pearly whites to grow through your gums, normally appearing after the age of 18, but before you turn 25. Technically, they are your final set of molars, and most often, they grow in with no problems. However, sometimes, they don’t have enough room and become tilted, displaced or twisted, causing pain and damaging other teeth.
Many people over the years have found a solution for whiter teeth, and have turned to whitening strips. Many people have turned to whitening strips because the strips are easy to get and use, and quick results that last over two years(1). Even with the benefits of whitening strips, many people don’t see that there are dangers of whitening strips(2). The ingredients that are in whitening strips are benefiting, but when used the wrong can have a deafening result.
