Apexification
When a child receives a blow to the mouth and injures a front tooth, there is always a chance that the blood supply to the dental pulp (or nerve) will be severed, causing the nerve to die. In this case, root canal treatment would be indicated. However, if the child is of a younger elementary school age, the end of the root has probably not matured yet. This is a situation called an open apex. The apex is the tip of a tooth root. In a normal root canal, an inert filling material is packed against the apex to seal the end of the root. With an open apex, there is nothing to pack against so there is no way to get a good seal. Fortunately, there is a procedure called apexification that will stimulate the body to close the apex. After the root canal has been thoroughly cleansed of debris, a calcium hydroxide paste is inserted at the root end. The calcium hydroxide is very alkaline. The body reacts to this high pH by depositing hydroxylapatite crystals (the basic building blocks of teeth) at the site. It takes a few visits spaced out over a year's time and then the canal can be properly sealed. Using this procedure will allow a front tooth to be retained, saving the child from years of embarrassment and numerous tooth replacements. Read More - Read More
Immediate Denture
A dentist's goal is to save teeth, however, if there is too much decay or gum disease or the financial situation is not good enough to properly restore the teeth, then the fateful decision must be made to remove the remaining teeth. There are two ways of handling the construction of the first set of dentures. One method is to wait for one full month to allow the gums to heal and shrink. At this point, an impression (or mold) is made of the gums and denture construction begins. The other method is an immediate denture. An immediate denture is constructed before the teeth are removed. The advantage of that is that the denture is inserted on the day of the surgery. This way the patient never has to go around without teeth. Unfortunately, there are compromises. There is no way to do a try-in to check the cosmetic arrangement of the teeth, the function, or phonetics (ability to speak with the dentures). It's possible that the resulting pre-made denture could be far enough off that it may have to be remade. The other issue is that the gums will shrink after surgery, so the denture will have to be relined after about six months. This way the inner part of the plastic of the denture will match the new healed gums. An immediate denture would at least save one from the embarrassment of being without teeth for any length of time. Read More - Read More
Denture Impressions - Preliminary Steps
The construction of a full denture starts with an impression of the gums. The dentist must first check to see if there are any suspicious lesions that could be a malignancy. X-rays should be taken to make certain that there are no tumors inside the bone. The dentist must also make certain that there are no bony undercuts which would prevent the denture from properly seating or flabby gum ridges which would not provide a stable surface for the denture to function. Any of these problems would require surgical intervention plus a healing period before final impressions could be made. The dentist must also check the condition of the gum tissue itself. If the gums are swollen, red, and inflamed especially due to sleeping in the dentures or from smoking, then steps must be taken to relieve the inflammation. Many times, merely leaving the dentures out while sleeping for a week or two will allow the gums to heal. In more resistant cases, a tissue conditioner can be applied to the current denture. This conditioner is a resilient liner. Its soft nature can give the gums a chance to heal. Once all of the preliminary steps have been taken, the final impression can be made. Read More - Read More
Denture Impressions
Once the dentist has done an oral cancer exam and checked for good health of the oral mucosa, then the patient is ready for an impression (or mold) in order to construct a complete denture. To make this impression, the dentist first prepares a tray to hold the impression material. This tray can be made in a lab from a preliminary impression or a stock tray can be modified to fit the mouth. The borders of the tray must be properly molded so that they do not protrude too high up into the cheek. If it did, then the resulting denture would constantly rub causing a sore spot. There are a number of impression materials available. The one I prefer to use is a vinyl polysiloxane. It has a rubbery consistency when set and is so accurate that I also use it for precision crown and bridge procedures. It also has a pleasant taste which can be a big factor when one has a mass of goo in their mouth. The material is mixed and placed in the mouth and allowed to set. A special plaster is poured into the resulting mold and a perfect reproduction of the patient's gums can be produced. Read More - Read More
Denture Try-Ins
A denture try-in is an extremely important phase of denture construction. One must start with a perfect reproduction of the gums obtained by taking an extremely accurate impression. The resulting models made from the mold are mounted on an articulator, a machine that is used to reproduce jaw movement. At this point, a lab technician sets the denture teeth into a wax base that will represent the gum portion of the finished denture. Now comes the try-in phase. The first thing that is checked is the bite. The denture teeth must meet the same way natural teeth do, so it is of utmost importance that a proper bite is verified before the dentures are constructed. Next comes the cosmetics. The dentist checks for the proper alignment of the front teeth to make sure that the patient has a great smile. The patient is then given a mirror so that they can approve the shape and color of the teeth. Since the teeth are set in wax, changes can be readily made by merely heating the wax and resetting the teeth. The patient is then instructed to say a few words to make certain that they will be able to properly speak with the dentures in. Lastly, the far extent of the hard palate is measured to make certain that the denture will not protrude too far to the back of the mouth. The denture is now ready to send to the lab for construction of the final product. Read More - Read More
X-rays in Dentistry (Part I of II)
X-rays were discovered in 1895 by German physicist, Wilhelm Röntgen. He also discovered the medical application of x-rays when he passed his hand in front of a barium screen and noticed a shadow of his skeleton. The ability to see inside the body has been a big boom for diagnosis in dentistry. A tiny burst of x-rays aimed between the teeth will show cavities in their early stages before they can be detected by visual examination. As the x-rays pass through the teeth, the high density of tooth structure will stop the x-rays from reaching the film. Decay is less dense because the acid from bacterial plaque leaches out the calcium. Therefore, more x-rays are able to pass through that point. The more x-rays that pass through, the darker the point on the x-ray film. The dentist will look at the film for dark spots against a white background in order to detect decay. The middle and later stages of gum disease can also be detected because the disease will attack the bone. With less density of the bone, the damaged bone will show up on an x-ray film as darker and therefore the extent of the disease can be better quantified. Read More
