Connection between obesity and dental health

Harvard researchers claim to have found evidence of obesity occurring prior to periodontal disease in a large group of people and suggest the two are connected.

Researchers from the Harvard School of Public Health and the University of Puerto Rico set out to answer the question of whether or not there was an association between obesity and one's dental health.

A total of 36,903 men from the Health Professionals Follow-Up Study were examined by the researchers. All participants were reportedly free of periodontal disease at the start of the study and were followed for 16 years. The men were mailed a questionnaire every two years with the participants self-reporting their obesity measurements as well as any indication of periodontal disease.

At the end of the study, it was found that those who were obese at the beginning of the research had a 25 to 29 percent increased risk of dental health problems when compared to men who were not obese.

The researchers concluded the study was significant due to the high prevalence of obesity in society. Health officials have recommended certain diets and nutritional supplements to maintain a healthy weight as well as routine dental care.

Connection between dental health and heart disease

Researchers have found two specific types of bacteria in the mouth that may be directly involved with causing heart attacks.

The study was conducted at the University at Buffalo, where the connection between gum disease and heart disease was first discovered, and found that Tannerella Forsynthesis and Preventella Intermedia had a "statistically significant association with an increased risk of heart attack."

"The message here is that even though some specific periodontal pathogens have been found to be associated with an increased risk of coronary heart disease, the total bacterial pathogenic burden is more important than the type of bacteria," said Dr. Oelisoa M. Andriankaja, who led the study. "In other words, the total number of 'bugs' is more important than one single organism."

A total of 386 men and women between the ages of 35 and 69 who had suffered a heart attack participated in the study, along with a control group of 840 people. Though the heart disease group had more bacteria in their mouth than the control group, they also had significantly more of two specific types of bacteria.

This discovery may lead to more urgings by dental care officials for people to schedule regular visits with a dentist.

RCT- Root Canal Therapy

Root Canal Therapy is one of the most important technique of dental treatment.It's also called as Endodontics.

A badly infected tooth, or one that just had significant decay, was doomed to be extracted. Today, the majority of these teeth can be salvaged by the Root Canal Therapy.

Some indications for the need of root canal treatment may be:

1) Spontaneous pain or throbbing while biting
2) Sensitivity to hot and cold foods
3) Severe decay or an injury that creates an abscess (infection) in the bone

Root canal treatment consists of:-

The removal of the infected or irritated nerve tissue that lies within the root of the tooth. It is this infected pulp tissue that causes an eventual abscess.

The first step in a root canal is to obtain access to the nerve. This is accomplished by establishing a small access opening in the top of the tooth. It will be done under a local anesthetic.

The length of the root canal is determined and the infected pulp is removed.

At the same visit, the canal where the nerve is located will be reshaped and prepared to accept a special root canal filling material. The number of visits necessary to complete your root canal will depend upon several factors including the number of nerves in the tooth, the infected state of the nerve, and the complexity of the procedure.

The final step in your root canal will be the sealing of the root canal with a sterile, plastic material called gutta percha. This is done in order to prevent possible future infection.

If treated early, root canal therapy need not be uncomfortable. With the use of local anesthetics, the entire procedure can be totally painless.

10 cheap ways to care for your teeth

Even in the best of times, dental care can be expensive. In these hard-pressed times, it's an expense many families are avoiding.

About half of 300 Chicago area dentists reported in a recent survey that people are putting off needed dental work. Also, 40 percent of dentists said patients are shying away from cleanings and other preventive care.

But taking care of your teeth doesn't have to cost a lost of money. Here are 10 inexpensive things to do that can make a difference, according to the Chicago Dental Society:

1) Drink plenty of water. It's a "natural" mouthwash that can help reduce stains left by coffee, soda and red wine.

2) Eat a piece of cheese. After dinner, munch on some cheddar - it can help neutralize acids in your mouth.

3) Chew sugar free gum. Chewing gum increases saliva production, which helps to wash away plaque acid and bathe teeth in needed minerals to strengthen tooth enamel.

4) Wait to brush after acidic drinks. After drinking orange juice and soda pop, don't reach for the toothbrush right away. Wait at least 20 minutes to reduce the chance of enamel wear.

5) Rinse with hydrogen peroxide. A small amount of H2O2 mixed with water makes a great anti-bacterial and whitening rinse after brushing. Just don't swallow!

6) Brush with baking soda, a gentle abrasive that can clean like toothpaste.

7) Use a straw. Might feel awkward to drink coffee or red wine through a straw, but doing so can help minimize direct contact between your pearly whites and these staining liquids.

8) Soften your toothbrush. Sensitive teeth can find relief from rough bristles by running the toothbrush under hot water before brushing.

9) Avoid sugar and starches. Both sugar and carbs can feed bacteria that causes tooth decay. It's just not the sweet stuff - a handful of crackers can have the same effect as a candy bar at feeding bacteria.

10) Brush and floss.

Human bone marrow synthesised in lab

Artificial bone marrow that can continuously make red and white blood cells has been synthesised in a lab for the first time. This could lead to simpler pharmaceutical drug testing, closer study of immune system defects and a continuous supply of blood for transfusions.

To determine whether the substance behaves like real bone marrow, the scientists implanted it in mice with immune deficiencies. They produced human immune cells and blood vessels grew through the substance.

Cancer-fighting chemotherapy drugs can strongly suppress bone marrow function, leaving the body more susceptible to infection.

The new artificial marrow could allow researchers to test how a new drug at certain potencies would affect bone marrow function, said Nicholas Kotov, co-author of the study and professor in University of Michigan departments of chemical and bio-medical engineering.
"This could assist in drug development and avoid severe side effects before human drug trials," he said.

The substance grows on a 3-D scaffold that mimics the tissues supporting bone marrow in the body, Kotov and Joan Nichols, professor at the University of Texas, collaborated on many aspects of the project.

"This is the first successful artificial bone marrow," Kotov said. "It has two of the essential functions of bone marrow. It can replicate blood stem cells and produce B cells. The latter are the key immune cells producing antibodies that are important to fighting many diseases."
Blood stem cells give rise to blood as well as several other types of cells. B cells, a type of white blood cell, battle colds, bacterial infections, and other foreign or abnormal cells including some cancers.

Bone marrow is a complicated organ to replicate, Kotov said. Vital to the success of this new development is the 3-D scaffold on which the artificial marrow grows. This lattice had to have a high number of precisely-sized pores to stimulate cellular interaction.
The scaffolds are made of a transparent polymer that nutrients can easily pass through. To create the scaffolds, scientists moulded the polymer with tiny spheres ordered like billiard balls. Then, they dissolved the spheres to leave the perfect geometry of pores in the scaffold.
The scaffolds were then seeded with bone marrow stromal cells and osteoblasts, another type of bone marrow cell, said a Michigan university release. The findings were published online in Biomaterials.
