Current literature suggests that amalgam waste from dental clinics is a point-source of mercury pollution in the environment. However, apart from mercury, other amalgam constituents (e.g. Ag, Sn, Cu, and Zn) in dental clinics' wastewater have not been reported in the literature before. The objective of this study was to evaluate the concentrations of mercury and other metals in the wastewater of some dental clinics and the influent of a wastewater treatment plant in Al-Madinah Al-Munawarah (KSA). Samples were collected over a 2-month period from three dental clinics and analyzed for metals using ICP-MS. The mean concentrations of Hg, Ag, Sn, Cu, and Zn in the samples were 5.3±11.1, 0.49±0.96, 3.0±10.7, 10.0±14.5, and 76.7±106mgL(-1), respectively. Additionally, high concentrations of other metals such as Mg (14.4±15.2mgL(-1)), Mn (3.0±4.6mgL(-1)), Fe (3.0±4.5mgL(-1)), Sr (1.6±2.4mgL(-1)), and Ba (6.9±10.3mgL(-1)) were also found. These values are much higher than the local permissible limits. Most of the metals of interest were also detected in the influent of the wastewater treatment plant. This renders dental clinics wastewater a hazardous waste which should be properly treated before it is discharged into the environment.

An Aspirin Please
In 1899, German doctors and pharmacists began receiving the first of the
sample packets from the drug company Bayer AG. The packets contained a fluffy
white powder, called acetylsalicylic acid, which Bayer executives described as
the latest modern miracle from the emerging field of organic chemistry. They
asked the practitioners, in modern terms, to pilot test the compound on their
patients, explaining that it had been shown in their initial human studies to
relieve common pain and inflammation minus the debilitating side effects of
other drugs. But, as they also explained, other uses certainly weren’t out of
the picture. Bayer encouraged the practitioners to publish their results and, in
a sign of 20th century things to come, to refer to the new drug by
its trade name. They called it Aspirin.
More than 110 years later, researchers continue to discover new uses for aspirin. In the December 2011 issue of the journal Nature Medicine, NIDCR scientists and grantees report in mouse studies that aspirin, applied directly to the site of an experimental skull wound, helps bone marrow mesenchymal stem cells, or BMMSCs, form new bone. Aspirin does so by reducing the concentration of immune cell signaling proteins INF-γ and TNF-α in the tissue microenvironment, where the wound healing occurs. By jamming these specific wavelengths of molecular communication, the scientists found they could control certain types of T cells that inhibit the implanted BMMSCs from forming new bone. Importantly, the aspirin has no negative effects on other T cells subtypes that the researchers found are helpful to engineer new bone.

Alternative Medicine: Herbal Dentistry, a Review
The sole purpose of any branch of medicine is to strive to make human life
happier and healthier. To achieve this we must use every possible resource
available. From time immemorial, we have been using our natural resources to
attain the state of well-being.
Herbal medicines are drugs of plant origin used to treat diseases or to attain or maintain a condition of improved health. Herbs with medicinal properties are a useful and effective source of treatment for various disease processes. Many drugs used in Western medical science (called allopathic medicine) have their origin in medicinal plants. Through this article, an attempt has been made to describe Ayurvedic resources to attain ‘Dantaswasthyam’. The word ‘Ayurveda’ is derived from: ‘Ayu’ meaning ‘life’ and ‘veda’ meaning ‘knowledge’. In its true sense, Ayurveda literally means the science that imparts all the knowledge of life.
Basics of Ayurveda
The body of man and all the objects in the universe are composed of some base elements namely earth, water, energy, air and space. ‘Vata’, ‘Pitta’ and ‘Kapha’ molecules are the three biological elements which constitute the cells and tissues of all the living organisms in the universe. The biological combination of Earth and Water gives rise to ‘Kapha’, Water and Energy to ‘Pitta’ and Air and Space to ‘Vata’. Kapha molecules make up the main structural units of the body. Pitta molecules represent the various enzymes and hormones and are responsible for digestion and release of energy impulses and all the movements of the body. When quantitatively and qualitatively normal, these three doshas (namely Vata, Pitta and Kapha) constitute the three pillars which stabilize life. But in a state of imbalance, the same three elements are responsible for disease, or even death.

Can Oral Care for Babies Prevent Future Cavities?
ScienceDaily (Aug. 15,
2011) - New parents have one more reason to pay attention to the oral health
of their toothless babies. A recent University of Illinois study confirms the
presence of bacteria associated with early childhood caries (ECC) in infant
saliva.
ECC is a virulent form of caries, more commonly known as tooth decay or a cavity. Cavities are the most prevalent infectious disease in U.S. children, according to the Centers for Disease Control and Prevention.
"By the time a child reaches kindergarten, 40 percent have dental cavities," said Kelly Swanson, lead researcher and U of I professor of animal science. "In addition, populations who are of low socioeconomic status, who consume a diet high in sugar, and whose mothers have low education levels are 32 times more likely to have this disease."

In the Mouth, Smoking Zaps Healthy Bacteria
Ohio State University
Feb 15,2012
According to a new study, smoking causes the body to turn against its own helpful bacteria,
leaving smokers more vulnerable to disease.
Despite the daily disturbance of brushing and flossing, the mouth of a healthy person contains a
stable ecosystem of healthy bacteria. New research shows that the mouth of a smoker is a much more
chaotic, diverse ecosystem and is much more susceptible to invasion by harmful bacteria.
As a group, smokers suffer from higher rates of oral diseases -- especially gum disease -- than do
nonsmokers, which is a challenge for dentists, according to Purnima Kumar, assistant professor of
periodontology at Ohio State University. She and her colleagues are involved in a multi-study
investigation of the role the body’s microbial communities play in preventing oral disease.
The smoker’s mouth kicks out the good bacteria, and the pathogens are called in, said Kumar.
So they’re allowed to proliferate much more quickly than they would in a non-smoking environment....

More Americans going to ER for dental maintenance
CHICAGO (AP) — More Americans are turning to the emergency room for routine dental problems — a choice that often costs 10 times more than preventive care and offers far fewer treatment options than a dentist's office, according to an analysis of government data and dental research.

Most of those emergency visits involve trouble such as toothaches that could have been avoided with regular checkups but went untreated, in many cases because of a shortage of dentists, particularly those willing to treat Medicaid patients, the analysis said.

More Americans seeking dental treatment at the ER
By LINDSEY TANNER AP Medical WriterAssociated Press
CHICAGO—More Americans are turning to the emergency room for routine dental problems—a choice that often costs 10 times more than preventive care and offers far fewer treatment options than a dentist's office, according to an analysis of government data and dental research.
Most of those emergency visits involve trouble such as toothaches that could have been avoided with regular checkups but went untreated, in many cases because of a shortage of dentists, particularly those willing to treat Medicaid patients, the analysis said.
The number of ER visits nationwide for dental problems increased 16 percent from 2006 to 2009, and the report released Tuesday by the Pew Center on the States suggests the trend is continuing.
