The oral cavity is home to a great variety of primitive organisms. It is the gateway to two of the most imperative body systems, the gastrointestinal and the respiratory systems. The oral cavity is the drainage to secretory glands called the salivary glands of which there is between 600-1000 small glands located throughout the mouth. They are exocrine glands that release their secretions through tiny ducts that open into the mouth. There are three major pairs of salivary glands however that contribute the most to the oral secretion and these are; the parotid gland, which is the largest and it is located at the back of the jaw, the submandibular gland, located in the lower jaw, and the sublingual glands, located under the tongue ( "Composition of Saliva 2010"). All salivary glands release the substance Saliva, which not only moistens the mouth, but it has a myriad of components that carry out differentiated functions within the mouth.
As insignificant as it may seem, Saliva is an expression of the status of many of the body's tissues, organs or even systems. It consists of 98% water and only 2% of it are substances whose concentrations and contents as secreted into the mouth are effective biological indicators ( " Saliva"). They change with illness, they change with a change in diet and they change periodically. The periodical change in the salivary secretions takes many forms and rhythms, monitored by internal biological clocks. These biological clocks are simply groupings of interacting molecules in cells and they are responsible for a great variety of oscillations in physiological processes in animals, plants, and even prokaryotes. In humans, all the biological clocks in the body are controlled by a "Master clock" in the...

Dr. Melissa N. Nitta loves the art of dentistry and working with her hands. As the owner of Tropical Smiles Dental in Kailua-Kona, Hawaii, she performs a variety of services, including root canals, tooth extractions and dental cleanings. She enjoys creating beautiful teeth, but says the best part of her job is interacting with patients.

What does it take to be a Dental Hygienist? As if scraping plaque and tartar off of teeth isn't fun enough, there is more to the job than you think.
The idea of phase advance and delay were first proposed by Aschoff and Pittendrigh (1960), but subsequent genetic studies have shown exact genes involved in phase delay and advance occurs due to over or under production of proteins as described in dorsophilia studies. Many knock out studies have shown that disruption of genes involve in circadian rhythm have created arrythmicity in animals. Low-Zeddies and Takahashi (2001), created clock mutants which were arrhythmic when exposed to dark condition. The period of clock mutants were greater when compared to wildtype mice. The mutant also showed higher phase-shifts hours and lower circadian amplitude.

Diabetes mellitus affects an estimated 20 million Americans, about 35 to 40 % of whom have not received a diagnosis. More than 9 % of the adult population has diabetes, and both the incidence and prevalence are increasing every year.” (Mealey, 2006, page 1) This is a scary statement. These numbers include our parents, aunts, uncles, sisters and brothers. We need to be aware that this is a real threat. Many of these individuals most likely have some type of periodontal issues as well, particularly if the diabetes is uncontrolled or not yet diagnosed. The health of the mouth can play a significant role in the overall health of the body.

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).
Infection control in dentistry crucial for the well being of employees as well as the patients. Many precautions must be taken to avoid serious illness or injuries.There are many steps and guidelines to follow in infection prevention but as employees in the dental office we must take the time to ensure no harm is done to the clients or ourselves.
Maintaining oral health is extremely important not only for your mouth, but for your overall health (Wallace, Taylor, Wallace & Cockrell, 2010). Poor oral health impacts a person’s quality of life and general health, It causes pain which could result in poor nutrition (Griffin, Jones, Brunson, Griffin & Bailey, 2012). The residents at Menarock aged care have a private dentist from Alpha dental that visits the facility when prompted, although some resident’s families take them to their own family dental professional.

In a majority of circadian rhythms there seems to be major components which include an endogenous component (which is regulated by an internal clock located in the hypothalamus) and an exogenous component. This exogenous component is made up of different clues in time in the world around us....
