The success of endodontic treatment is directly influenced by elimination of microorganisms in infected root canals.
With apical periodontitis, effective antimicrobial agents are necessary.
The irrigant solutions are very important during root canal preparation because they aid in the cleaning of the root canal, lubricate the files, flush out debris, and have an antimicrobial effect and tissue dissolution, without damage to periapical tissues.
The selection of an ideal irrigant depends on its action on microorganisms and periapical tissues.
Chlorhexidine is a cationic agent (biguanide group; 4-chlorophenyl radical), which exhibits antibacterial activity.
The cationic nature of the compound promotes connection with anionic compound at the bacterial surface (phosphate groups from teicoic acid at Gram-positive and lipopolysaccharide at Gram-negative bacteria) capable of altering its integrity.
The potassium ion, being a small entity, is the first substance to appear when the cytoplasmic membrane is damaged.
The alteration of the cytoplasmic membrane permeability promotes precipitation of cytoplasmic proteins, alters cellular osmotic balance, interferes with metabolism, growth, cell division, inhibits the membrane ATPase and inhibits the anaerobic process.

Farewell Toothbrush And Dentists’ Drill
Amazing but true – the dentist’s drill, which has featured as the main villain in the mass phobia of dental check-ups, is on its way out!
Joining the drill on the endangered list is the toothbrush.
Both these items can lay the blame at the door of researchers at the Leeds Dental Institute.
While the replacement for the drill is a derivative from a new protein that facilitates natural repair of holes in the tooth enamel, the toothbrush’s replacement is a new kind of mouthwash.
While the drill has a slightly longer time to go, approximately five years from now, the toothpaste could become history over the next three years itself.
The two radical new inventions are set to change the world of dental care.
The prospective replacement for the drill, the new protein, would basically build a scaffold to attract the minerals that form tooth enamel. Painting the substance on the teeth can arrest damage in the early stages of decay. The same treatment could also be used to fill ruptures in the teeth's dentine, which cause sensitivity to hot and cold food.
The new mouthwash, which is part of a photo dynamic therapy, uses a molecule to destroy bacteria in the mouth when activated by a high-intensity light. It proposes to do away with the toothbrush as a manner of fighting plaque.
Prof Jennifer Kirkham, Research Director at the institute where the research was done, said the mouthwash and photo therapy could also be used to treat gum disease and kill bacteria through insertion below the gum line with a small fiber optic light source.
While the inspiration behind the photo dynamic therapy was cancer treatment; the alternative to drilling took shape as a way to surmount the fear psychosis associated with the drill.
However, both the inventions have a long way to go before they are unleashed on to the market.
They would first have to undergo a series of trials and safety checks, and only after they cleared the tests and checks could one think of getting them in the market.
Speaking about the new mouthwash, Prof. Kirkham said, “At the moment we are not saying it is going to take over from brushing because the trials have not been done yet. We have to look at how much it is going to cost, at the moment is it is very cheap.”
Prof. Kirkham added, “We would wish to explore its full potential across the whole patient community and look at all the potential benefits over and above what is already out there.”
The team of researchers will be based at the new translational research center due to be opened next year following a £1.5 million investment by the University of Leeds.

how to survive a heart attack when alone
Hi,
Let's say it's 6.15p m and you're going home (alone ofcourse), after an unusually hard day on the job.
You're really tired, upset and frustrated.
Suddenly you start experiencing severe pain in your chest that starts to radiate out into your arm and up into your jaw.
You are only about five miles from the hospital nearest your home.
Unfortunately you don'tknow if you'll be able to make it that far.
You havebeen trained in CPR, but the guy that taught the course did not tell you how to perform it on yourself.
HOW TO SURVIVE A HEART ATTACK WHEN ALONE
Since many people are alone when they suffer a heartattack, without help, the person whose heart is beating improperly and who begins to feel faint, has only about 10 seconds left before losing consciousness.
However,these victims can help themselves by coughing repeatedly and very vigorously.
A deep breath shouldbe taken before each cough, and the cough must be deep and prolonged, as when producing sputum from deep inside the chest.
A breath and a cough must be repeated about every two seconds without let-up until help arrives, or until the heart is felt to be beating normally again.
Deep breaths get oxygen into the lungs and coughing movements squeeze the heart and keep the blood circulating.
The squeezing pressure on the heart also helps it regain normal rhythm.
In this way, heart attack victims can get to a hospital.
Tell as many other people as possible about this.
It could savetheir lives!!
