PAIN: THE UNIVERSAL DISORDER

It comes all of a sudden, as a weird sensation or a dull ache or can be a sharp pierce. It is nothing but the pain. In its early stages, it warns us that something is going wrong and we should take medicine or see a doctor. As it is worst, it makes our lives miserable.

Earlier humans considered pain as an evil or a demon or magic. The Greeks and Romans were the ones to advance the theory of sensation, the idea that the brain and nervous system play a role in the perception of pain. Later, Leonardo da Vinci and his contemporaries believed that brain is the central organ for perception or sensation. They also stated that the spinal cord transmits sensations to the brain.

Now you must be wondering what exactly happens in our body that causes pain?

Well, there are microscopic structures called pain receptors throughout our body. When a painful event happens, the damaged area releases chemicals, which in turn excite the nerve fibers. They transmit the pain signals to the spinal cord where the pain intensity is filtered and modified and then sent to the sensory cortex of brain through a bundle of nerve fibers which makes the person perceive the pain.

How is the pain treated?

The body’s own pain killers have proven to be the most effective pain relievers. The brain may signal the spinal cord to release the pain killers.

One way of relieving pain from outside the body is by inhibiting the hormones like prostaglandins which stimulate the nerve at the site of injury and cause inflammation and fever. Certain drugs like NSAIDs act against these hormones by blocking the enzymes required for the release of these hormones.

How does the pain killer act in the body?

The mechanism of pain killers (analgesics) is inhibition of prostaglandin synthesis. This reduces pain and inflammation.

What is drug tolerance?

When a person needs higher doses of the drug as the person’s reaction to the drug reduces though the dose at the effect site is the same is known as drug tolerance. This means larger doses of the drug is required to achieve the same effect. This occurs due to continuous intake of the drug.
When a specific molecule is present in higher levels in the brain through regular use of a drug, the brain adjusts accordingly. It changes the level of the chemicals which it produces to compensate the increased levels of the drug taken.

The best way to prevent tolerance is to reduce the use of drugs.

OZONE THERAPY

Most of the people have the fear for dentistry which ultimately keeps them away from dental treatments.

People fear from the injections and drills that are used during the dental procedures. But in recent times dentistry has been experiencing dynamic changes and growth as never before.

The use of Ozone in dentistry is a boon to the patients who fear extensive dental treatments. The implementation of Ozone would eradicate the pain during the dental treatment and even reduce the treatment time.

Ozone is a gas composed of three oxygen atoms and is naturally present in the upper layer of the atmosphere. It has got the capacity to absorb harmful UV rays from the sun. Ozone is an unstable gas which gives up nascent oxygen to form oxygen gas. Due to this property It is used in human medicine to kill bacteria, fungi and inactivate viruses.

Ozone can do wonders when implemented in dentistry:

• Rinsing and gargling with ozonated water heals ulcers, periodontal problems, soar throat, etc.

• It can stimulate remineralization of recently caries affected teeth after a period of about eight to six weeks.

• It can be used to bleach a discolored tooth.

• Ozone oils can be used to irrigate and sterile root canals to remove the necrotic debris.

• Root Canal Treatment can be prevented with ozone. The exposed nerve is washed with ozonated water followed by ozone gas that prevents the nerve from dying.

• Ozone sprayed for 60secs followed by mineral wash gives quick relief from root sensitivity.

• It can accelerate the healing of soft tissue conditions like aphthous ulcers, gum infections and also reduces the post-extraction healing time.

• It is used to disinfect wounds and control bleeding.

Ozone seems to be a promising treatment modality in medicine and dentistry in coming future.
