Root Canal Therapy
Root Canal Resources
Root canal therapy is called endodontics. The recognized specialty group is the American Association of Endodontists (AAE) , which has more than 6,500 professional members.[4] Root canal therapy is a well-known procedure wherein the crown of a diseased tooth is opened so as to permit the canal to be cleaned and then filled. More particularly, as presently performed, a series of very delicate, flexible, finger-held instruments or files are used to clean out and shape the root canal, and each file is manually rotated and reciprocated in the canal by the dentist.[5] Root canal therapy is completed after a negative culture is obtained. [6] Root canal therapy is a process that is carried out within the root canals of the tooth. These canals run vertically within the roots of a tooth.[7] Root canal therapy is designed to correct disorders of the dental pulp - the soft tissue inside the tooth that contains nerves, blood vessels, and connective tissue. Teeth with abscessed, or infected, nerves were once removed with corrective therapy.[8] Root canal therapy is usually not painful. With the effective use of anesthesia and modern techniques, most root canal therapy can be completed in one visit, and within one hour.[9] Root canal therapy is done to remove damaged pulp and prevent further infection. The procedure usually requires one or two office visits.[10] Root canal therapy is used when the crown is injured or there are fillings or crowns that are too close to the gum and cause infection. Endotomy is the procedure, when the infected tissue is removed from the root canal .[11] Root canal therapy is a type of procedure that enables the patient to keep the original tooth by filling the canal with gutta percha (a rubber-like material), to prevent recontamination of the tooth. The tooth then will be permanently sealed with porcelain or gold, depending upon the patient choice.[12] Root canal therapy is necessary when the pulp inside the canal becomes infected. Root canal therapy is a complex procedure and requires the expertise and skill of a seasoned dentist.[13]
Pulp can also die because of injury due to trauma. Damaged or dead pulp causes increased blood flow and cellular activity and pressure cannot be relieved from inside the tooth.[16] Pulp is a collection of blood vessels that helps to build the surrounding tooth. Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures.[17]
Dentist will make an opening in your tooth and will remove any existing fillings or decay. Then your dentist removes unhealthy pulp with tiny, flexible files.The pulp is removed from your root canals through a small opening in the crown.[20] Dentists call this sheet of rubber a "rubber dam.".It is held in place by a small clamp that grasps your tooth. The purpose of a rubber dam is as follows.[21] Dentistry teaches that a root canal must be filled to within 1mm of the root apex. The apex of a root canal is only rarely determinable by X-ray.[22] Dentists now must be educated on the current concepts in order to optimally perform a root canal. Root canal therapy has become more automated and can be performed faster, thanks to advances in automated mechanical instrumentation of teeth and more advanced root canal filling methods.[23]
Teeth with abscessed, injured or infected pulpal tissues require to have endodontic or root canal therapy to remove the necrotic or infected pulpal tissue. In ideal situation there is a 95 percnet chance of success in the outcome of root canal therapies.[24] Teeth with abscessed, or infected, nerves were once removed with corrective therapy. But now, in 95 percent of these cases of pulpal infection, the natural tooth can be saved through modern endodontic procedures.[25] Teeth that have had crowns on after root canal therapy generally have much higher success rates than those that don't. [26] Teeth may also shift their position if missing teeth are not there to hold the space. If you decide to have the dentist pull the tooth and replace it with a denture or bridge , the cost will be significantly more than the cost of a root canal.[27] Teeth on the side of the mouth called premolars usually have one or two roots and one or two root canals. The upper back teeth (molars) usually have three roots, and three or four root canals.[28] Treatment does kill most bacteria in the root canal, but Price found that not one of the over 100 disinfectants he studied was capable of penetrating the tubules. The same holds true for antibiotics today.[29] Treatment involves removing decay, restoring the damaged tooth, and, sometimes, performing root canal therapy or extracting the tooth. [30] Treatment may take one or more visits. The tooth is first numbed.[31] Treatment is provided while looking at your tooth through a surgical microscope. It provides unparalleled vision and treatment capability during root canal therapy.[32] Treatment is limited to curettage of the area to remove all diseased material. [33] Infection of the pulp can be caused by trauma to the tooth, deep decay, cracks and chips, or repeated dental procedures. Symptoms of the infection can be identified as visible injury or swelling of the tooth, sensitivity to temperature, or pain in the tooth and gums.[34] Infection in a deep periodontal (pyorrhea) pocket may extend to the nerve, requiring a combination of endodontic and periodontic therapy to save the tooth. Nerve degeneration might also be due to poor dental treatment.[35] Infection after root canal? Staph infection from root canal?[36]
Bacteria can then move in through anachoresis (the process of bacteria lodging in an area of previously damaged tissue), causing a myriad of problems ranging from internal inflammation to an apical abscess. [38] Bacteria can get into this chamber either from dental decay or directly from the mouth if a filling is lost. Once bacteria are established, blood supply to the nerve diminishes and the tooth begins to die.[39]
Pain and swelling in the surrounding gum and sometimes tenderness on biting. The pain initially may be difficult to pinpoint and sometimes may move between the upper and lower jaw on the same side of the face.[41] Pain control medication may be used either before or after treatment. [42] Pain usually worsens until one is forced to seek emergency dental attention. The only alternative is usually extraction of the tooth, which can cause surrounding teeth to shift crookedly, resulting in a bad bite.[43]
Nonsurgical endoontic therapy is like any other medical procedure, with a small percentage that are unsuccessful. Whether it's called failing, unsuccessful, nonresponder, or it did not respond favorably, something has gone amiss.[45] Nonsurgical retreatment of endodontic therapy has a good success rate. Typically somewhere between 50 - 85% with 70% being common![46]
Endodontic treatment (commonly referred to as root canal therapy) involves removing the infected or inflamed dental pulp (commonly called the nerve). This inflammation or infection can have a variety of causes such as deep cavities, fractures of the tooth, or trauma to the tooth.[49] Endodontic treatment is indicated to preserve a tooth when: A fracture of the crown exposes the pulp chamber. A cavity has perforated the pulp chamber.[50] Endodontics involves cleaning, shaping and obturation of the root canal system. To improve success in endodontics, each of these steps should be evaluated throughout treatment to determine the effects of each stage of therapy.[51] Endodontic symptoms usually come and go or rise and fall in intensity, making diagnosis accurate only if and when symptoms are present. [52] Endodontics is the dental specialty devoted to root canal therapy. [53] Endodontic points are provided comprising hydrophilic, polymeric compositions. Such points are swellable when placed into a prepared root canal space and provide substantially complete filling of lateral cavity spaces without invasion of the subapicial space.[54] Endodontic treatment is required when the pulpal contents are undergoing an irreversible degenerative inflammatory process or are necrotic and the tooth is needed as a functional part of the dentition. Many signs of the endodontically involved tooth may be observed at various times during the affected animal's distress.[55] Endodontics, also commonly known as Root Canals or Root Canal Therapy, is the prevention, diagnosis and treatment of disorders of the dental pulp (the soft tissue inside the tooth). The pulp of the tooth contains nerves, blood vessels, and connective tissue, which are important in tooth development.[56] Endodontic therapy or root canal treatment, has changed in recent years. Most notably it is a lot less painful.[57] Endodontics is a scientific term for root canal therapy that is meant to save you from this serious matter. [58] Endodontic treatment, commonly known as root canal therapy, is performed in a number of situations. The most common reason would be as an alternative to extraction of an otherwise healthy tooth that has been fractured.[59]
Medications are put in the pulp chamber and root canal to help get rid of gems and prevent infection. A temporary filling is placed in the crown opening to protect the tooth between dental visits.[65] Medication )Tj ET BT /T1_2 1 Tf 8.5 0 0 8.5 434.0884 569.1868 Tm [(may be inserted into the area to \037)334( )-55(ght )]TJ ET BT /T1_2 1 Tf 8.5 0 0 8.5 434.0884 558.9868 Tm (bacteria.

Patients requiring root canal therapy are either referred by their general dentists to the endodontist or are self-referred. [67] Patients tell dentists the joke backwards: "I'd rather visit my ex-husband or go to my class reunion than get a root canal.".Root canal therapy is a much maligned dental procedure. Once the infected tooth is treated with antibiotics, the infection subsides, and a trained specialist performs the root canal therapy, the procedure usually goes quite smoothly.[68] Patients should ask to see the final x-ray following root canal therapy . It's better to get something done right the first time in a premium dental practice.[69] Patients usually return home and fall asleep after the treatment. It is common for many to wake up and remember little or nothing about the procedure.[70] Patients may also feel sick or weak because their body is trying to fight an infection, just like it would as if the infection occurred anywhere else in the body. If left untreated for too long, the tooth may not be able to be saved and the tooth will need to be extracted.[71] Dental implants are a very valuable in the replacement of missing teeth; however, their success is determined quite differently than that of root canal therapy. With implants, success can have many different definitions, including those that would be considered by many clinicians and patients as failure.[73] Dental infections of all kinds certainly have been linked to health problems, but teeth well treated with root canal therapy are no longer the culprits that they once were. [74]
Price did not say that root canal therapy should be abolished. Rather, he stated there are potential serious side effects and that the health of a person's immune system must be considered before performing a root canal procedure.[79] Price concluded that the toxins produced by the infected tooth found there way into the blood stream and was capable of causing disease within specific organs. In the 1940's, the medical and dental professions both recognized such problems as valid and provided the basis for recommendations of tooth removal.[80]
Inside each tooth is a canal(s) that contains the nerves and blood supply for the tooth. When the nerve becomes infected due to decay or injury, it must be removed from the canals of each root.[82] Inside the canals of our teeth is pulp tissue, when this becomes infected it causes pain and a toothache. This infection can further damage the tooth if it is not removed.[83]
