Dental Extractions

Dental extractions are among the easiest and best ways to get relief from a toothache. As the name implies, an extraction involves removing the tooth. If your pulp has died or the tooth has become severely infected, extraction may be your only route. Depending on the tooth, the dentist can do either a simple extraction or a more complicated extraction.

Simple extractions
These types of extractions, the simple extractions, are the most common in the world of dentistry. During a simple extraction, the dentist will remove the tooth by loosening the gums around the socket. He will grasp the tooth with forceps and move it from side to side until he can get it to break free from the socket and remove it.

The teeth are held to the bone by a thin piece of soft tissue. This soft tissue is known as the periodontal ligament. The dentist uses this tissue to remove the tooth. As you may know, the key to removing a tooth by pulling is to rock the tooth from side to side, which enlarges the socket in the bone and breaks the ligament that helps to hold the tooth in place.

Simple extractions, also known as pulling, dont take long to complete. The dentist will numb you before he starts, so you wont feel anything. Depending on the tooth, pulling it will normally take just a few minutes after you have been numbed with local anesthesia. Once completed, the dentist will place gauze in your mouth to bite on and you will be free to go.

Complex extractions
As we all know, not all teeth can be pulled. Sometimes, the tooth will be so decayed or broken off that the dentist will have nothing to grasp above the gum line. In cases such as this, the dentist will need to perform a more complicated extraction, which involves getting the tooth out below the gum line, as he wont be able to use the standard method of pulling and rocking.

These types of extractions involve the dentist making an incision in the gums around the tooth, and raising the flap he cut to expose the bone. Once he has exposed the bone, there may be enough of the tooth exposed for the dentist to grab and remove it using the pulling method. In most cases however, the tooth will be embedded in the bone, meaning that the dentist will be unable to pull the tooth out.

With teeth that are imbedded in the bone, the dentist will need to use a drill and chip away at the bone to get to the tooth. This is known as cutting the tooth out, and happens to be very common with impacted teeth or teeth that are severely decayed. Once the dentist has cut his way to the tooth and removed it, he will sew back the flap of skin that he cut to get to the tooth. The flap of skin and the socket will heal over time – providing you take care of it.

Dental extractions are very common, and happen on a daily basis for dentists. Oral surgeons are the best for extractions, as extractions are all they do. All types of extractions, even the most complex, will take time to heal. As long as you take care of your extraction site, youll avoid common pitfalls such as dry sockets and other mishaps. Although they can be painful once the procedure is over – youll eventually start to feel a lot better once you have had the tooth or teeth removed.

Advancement in Hair Transplantation

A standard hair transplantation procedure involves the removal of donor strip of hair from the back of the head from where the follicular unit grafts are dissected under a microscope. These grafts are then preserved in saline and are then transplanted on a bald patch on the crown area of the scalp.

Given the time consuming and tedious nature of this procedure, a hair transplant surgeon is often able to transplant only about 500 to 600 follicular unit grafts per day. However, thanks to the recent hair transplant advances, this technique is often replaced by the follicular unit extraction (FUE). The cost per graft of FUE is typically twice the cost of the standard follicular unit hair transplant procedure discussed above but it is comparatively faster and minimally invasive.

Some hair transplant advances

In a typical FUE procedure a small round punch is made in the donor area to directly extract 1, 2, 3 and 4 hair follicular unit grafts. The follicular units extracted using this process is typically referred to as “blunt dissection” where a punch is made to envelope the entire follicular unit separating it from the surrounding soft tissues.

Once the underlying follicular unit is separated from the surrounding tissues, it is easily extracted using a small forceps. The small holes left behind after the follicular unit extraction gradually heal over the next few days and are not detectable to the naked eye once the patient’s hair grows out. The healing time is much less than the donor strip extraction procedure.

While the FUE procedure has been adopted by most hair transplant clinics, the standard strip excision method is still the most popular hair transplant procedure because it is more economical than the FUE.

Moreover, due to some recent hair transplant advances such as the use of trichophytic closure technique, the linear donor scar created by the strip excision procedure is now often rendered almost undetectable to the naked eye. This advancement in the hair transplantation technique has made FUE procedure relatively less appealing.

Hair transplantation research

Besides the hair transplant advances in the transplantation procedures, a lot of research is also underway to clone the hair. If the hair transplantation research is successful it will be possible to make several copies of donor hair in the laboratory. The application of this technique would be used in the form of hair transplantation. In the traditional procedures, the biggest limitation is often the donor which is not able to meet required density. However, hair cloning promises to overcome this problem by having the amount of hair required to be grown in a laboratory from a single donor hair and then implanting it into the scalp.

Hair transplantation research for cloning is very difficult and there are many hurdles that have to be overcome regarding the safety and cosmetic characteristics of the cloned hair. Some hair transplantation research has also provided breakthrough for some hair loss medication like Dutasteride.
