Root Resection
Root resection or root amputation is a type of periradicular surgery in which an entire root of a multiroot tooth is removed. It contrasts with an apicoectomy, where only the tip of the root is removed, and hemisection, where a root and its overlying portion of the crown are separated from the rest of the tooth, and optionally removed. The procedure will first start with the doctor injecting the area with local anesthesia, after which an incision is created at the gum tissues around the affected root to allow your specialist to have access to the infected peri-apical tissues. This procedure can help your dentist remove infected and damaged tissues in the root area. Also, to prevent the risks of infection, a small filing is inserted at the end of the root canal. Lastly, to close the gum tissues, sutures will be placed to completely close the incision. After it is completely healed for a week, the bone will be back to its normal function. Patients who undergo root resection are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periradicular Surgery
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy, root resection, repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures. Symptoms may be due to infection in the periradicular tissue around a root-treated tooth, which can impede healing of the tooth after conventional root canal treatment. After removing the pulp, the aim of endodontic treatment is to seal the pulpal space to prevent further bacterial contamination and allow healing of the periradicular tissue. Success rates for root-canal treatment range from 47 to 97 percent; failures may be due to spaces in the root-canal filling, a root filling which is too short or a preexisting periapical lesion. Treatment options are nonsurgical root-canal re-treatment or periradicular surgery. Although accessing and clea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apicoectomy
A root end surgery, also known as apicoectomy ('' apico-'' + ''-ectomy''), apicectomy ('' apic-'' + ''-ectomy''), retrograde root canal treatment (''cf.'' orthograde root canal treatment) or root-end filling, is an endodontic surgical procedure whereby a tooth's root tip is removed and a root end cavity is prepared and filled with a biocompatible material. It is an example of a periradicular surgery. An apicoectomy is necessary when conventional root canal therapy has failed and a re-treatment was already unsuccessful or is not advised. Removal of the root tip is indicated to remove the entire apical delta ensuring no uncleaned missed anatomy. The only alternative may be extraction followed by prosthetic replacement with a denture, dental bridge or dental implant. State-of-the-art procedures make use of microsurgical endodontic techniques, such as a dental operating microscope, micro instruments, ultrasonic preparation tips and calcium-silicate based filling materials.

Tooth Hemisection
Tooth hemisection is a type of endodontic surgery in which a root and its overlying portion of the crown are separated from the rest of the tooth; the separated part may be optionally removed. It contrasts with root resection, where a root is removed while leaving the crown intact, and an apicoectomy, where only the tip of the root is removed. A hemisection is only performed on molars, which have 2 to 3 roots. Incisors, canines, and lower premolars only have 1 root each. Hemisections are also usually performed on the lower molars rather than the upper molars. During a hemisection, a general dentist or periodontist cuts the molar in half. The root and crown on the affected side are removed. The dentist will make a small incision in the gum tissue to expose the deeper structure of the tooth A tooth (: teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores and omnivores, als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Anesthesia
Local anesthesia is any technique to induce the absence of sense, sensation in a specific part of the body, generally for the aim of inducing local analgesia, i.e. local insensitivity to pain, although other local senses may be affected as well. It allows patients to undergo surgical and dentistry, dental procedures with reduced pain and distress. In many situations, such as caesarean section, cesarean section, it is safer and therefore superior to general anesthesia. The following terms are often used interchangeably: * ''Local anesthesia'', in a strict sense, is anesthesia of a small part of the body such as a tooth or an area of skin. * ''Regional anesthesia'' is aimed at anesthetizing a larger part of the body such as a leg or arm. * ''Conduction anesthesia'' encompasses a great variety of local and regional anesthetic techniques. Medical A local anesthetic is a medication, drug that causes reversible local anesthesia and a loss of nociception. When it is used on specific ne ...

Root Canal
A root canal is the naturally occurring anatomic space within the root of a tooth. It consists of the pulp chamber (within the coronal part of the tooth), the main canal(s), and more intricate anatomical branches that may connect the root canals to each other or to the surface of the root. Structure At the center of every tooth is a hollow area that houses soft tissues, such as the nerve, blood vessels, and connective tissue. This hollow area contains a relatively wide space in the coronal portion of the tooth called the pulp chamber. These canals run through the center of the roots, similar to the way graphite runs through a pencil. The pulp receives nutrition through the blood vessels, and sensory nerves carry signals back to the brain. A tooth can be relieved from pain if there is irreversible damage to the pulp, via root canal treatment. Root canal anatomy consists of the pulp chamber and root canals. Both contain the dental pulp. The smaller branches, referred to as '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oral Hygiene
Oral hygiene is the practice of keeping one's oral cavity clean and free of disease and other problems (e.g. bad breath) by regular brushing of the teeth (dental hygiene) and adopting good hygiene habits. It is important that oral hygiene be carried out on a regular basis to enable prevention of dental disease and bad breath. The most common types of dental disease are tooth decay (''cavities'', ''dental caries'') and gum diseases, including gingivitis, and periodontitis. General guidelines for adults suggest brushing at least twice a day with a fluoridated toothpaste: brushing before going to sleep at night and after breakfast in the morning. Cleaning between the teeth is called interdental cleaning and is as important as tooth brushing. This is because a toothbrush cannot reach between the teeth and therefore only removes about 50% of plaque from the surface of the teeth. There are many tools available for interdental cleaning which include Dental floss, floss, tape and interden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medication
Medication (also called medicament, medicine, pharmaceutical drug, medicinal product, medicinal drug or simply drug) is a drug used to medical diagnosis, diagnose, cure, treat, or preventive medicine, prevent disease. Drug therapy (pharmacotherapy) is an important part of the medicine, medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management. Drugs are Drug class, classified in many ways. One of the key divisions is by level of controlled substance, control, which distinguishes prescription drugs (those that a pharmacist dispenses only on the medical prescription) from over-the-counter drugs (those that consumers can order for themselves). Medicines may be classified by mode of action, route of administration, biological system affected, or therapeutic effects. The World Health Organization keeps a list of essential medicines.
