The term tooth resection denotes the excision and removal of any segment of the tooth or a root with or without its accompanying crown portion. Various resection procedures described are : root amputation, hemisection, radisection and bisection. Root amputation refers to removal of one or more roots of multirooted tooth while other roots are retained. Hemisection denotes removal or separation of root with its accompanying crown portion of mandibular molars. Radisection is a newer terminology for removal of roots of maxillary molars. Bisection / bicuspidization is the separation of mesial and distal roots of mandibular molars along with its crown portion, where both segments are then retained individually.This is a review of various literatures citing Hemisection and Bicuspidization
When I first moved to Sedona, I fainted and fell face down on a concrete pad. I broke my incisor tooth, which pushed the front tooth next to it out of alignment. I was devastated. Over time the two teeth slowly died. My conventional dentist urged me to have root canals which I eventually did because I did not know what else to do. Dentistry offers very few choices when a tooth becomes badly damaged or dies. The tooth can either be extracted or a procedure called a root canal can be done to “save the tooth.”
While the tooth is numb, a rubber dam (a sheet of rubber) will be placed around the tooth to keep it dry and free of saliva. An access opening is made on top of the tooth and a series of root canal files are placed into the opening, one at a time, removing the pulp, nerve tissue, and bacteria. If tooth decay is present, it will also be removed with special dental instruments.
In this experiment, 30 human teeth were separated into three groups: control, hydrogen peroxide, and carbamide peroxide. In the control group, the teeth were etched with 37% phosphoric acid gel for 45 seconds and then distilled water was used to rinse off the gel. An LED curing light was used to cure each tooth for 45 seconds, and then remained on the tooth for 3.5 minutes before any remaining phosphoric acid gel was rinsed off with distilled water. For the teeth labeled “Carbamide”, the same method applied to the control group was used here. After the brackets had been applied to each tooth, 3 mm of the 36% carbamide peroxide gel was brushed onto the teeth until the enamel was fully
These conditions shape a cycle of occasions, even in infants, that gradually unwind oral health: rot creating microscopic organisms associate with the starches (sugars) to deliver corrosive; the corrosive in constant contact with the teeth gradually demineralizes (breaks down) the tooth veneer; as demineralization proceeds with, serious cavity problem
However, when most people hear the term root canal, they become tense or scared. The procedure itself has a negative reputation, even though it is the solution to a common tooth problem. The inside of every tooth contains a material called pulp. This material is soft, and surrounds the root of the tooth. The root of the tooth is directly connected to the nerves within the teeth and jaw. For various reasons, including deep cavities, too many dental procedures in one area, tooth injuries or cracks, the pulp becomes exposed to the elements. When this happens, food and drink work their way into the delicate pulp and cause an infection. Essentially, the pulp becomes diseased. This leads to extreme pain and swelling, with the possibility that the infection can spread to the rest of the
Teeth come in different shapes and sizes and everyones ' teeth are different. However all teeth have a few things in common- they all have three main layers; Enamel, Dentin, and Pulp. Enamel is the very hard protective shell on the visible part or crown of your tooth. It can withstand chewing and biting but is brittle and can chip/break easily. Dentin consists of a substance that is similar to bone, it is underneath the enamel and gives your teeth their color. Last is pulp, pulp is inside of the pulp cavity beneath dentin. Pulp is made of nerves, blood vessels, and connective tissue. Pulp gives your teeth the nutrients they need to live and not fall out or get infected.
(Hajishengallis,2014). Gingivitis, which comes before periodontitis, is an inflammation of the gums. The development of plaque from bacteria causes the gums to swell. This doesn 't bring about quick harm to the bones and tissues, however it results in disturbance of the gums. Following untreated gingivitis is periodontitis (Hajishengallis,2014). Periodontitis is the predominant damage of the periodontium, which can be the supporting tissues and bones of the teeth. This advanced form of gingivitis is also resulting from a microorganism that remains inside the mouth, which brought about infection as properly. The signs and symptoms of periodontal disease can range from a simple gum infection to fundamental harm of the the helping functions of the teeth
Dentin is the second hardest mineralized substance, contains living tissue, and contains a plethora of nerves that connect down into the root of the tooth and jaw bone. Pulp is underneath the protective layer of dentin, is located in the center of the tooth, and is composed of soft connective tissue that has a complex bundle of nerves. The cementum is the layer of connective tissue that acts like glue and holds the roots of teeth in the gums and jawbone, but not to be confused with the periodontal ligament. This ligament is also tissue, but it holds the teeth themselves against the jaw bone. The final segment of the tooth is the root. The root is the base for stability of teeth and can vary on number of roots for different teeth based on their function. Roots derive to the jaw bone and contain nerve endings and blood vessels.
The infamous "root canal" is a procedure that requires filling the damaged areas of your tooth with a rubber-cement type material that seals the cracks, improves your smile, and helps hold your tooth in place. A corrective crown is then placed on top to eliminate any signs of repair.
Sodium hypochlorite is unable to remove smear layer during root canal therapy. Therefore, usage of NaOCl prior or after instrumentation produces superficially clean canals with the presence of smear layer 16,17,18,19. Although, when used alternatively with EDTA, removal of smear layer as well as soft tissue and debris is achieved. NaOCl gets inactivated with EDTA remaining active for a few hours 19,20,21,22. 92% of the non-endodontists were not aware about the use of sodium hypochlorite as a bleaching agent and considered irrigation to be its only use. Liquid chlorine bleach, an alkaline solution of sodium hypochlorite is highly effective on white fabrics and provides germicidal activity as
Well, although it is known as “wisdom” tooth, people who don't develop it are said to be lucky! Have you ever thought about why these third set of molars are popularly known as Wisdom teeth? Why do some people don't develop them at all? And why there are many who go through this extreme pain and discomfort?
odds of finding hyperplasia, stomatitis, and angular cheilitis increase 3-fold in denture wearers . Such problems could expose the individual to internal and external pathogens, and their prevalence is an important scale in evaluating the oral health of an elderly. [39, 40]. The majority of oral mucosal problems in the elderly are mild, some may become problem, especially if the protective functions of oral mucosa are reduced
The CBCT showed that the root fragment “socket shield” was still intact, clinically the site was healed, for no signs of infection was observed, there was no swelling, no exudates, no pain, and the most important finding was the retaining socket shield which wasn’t rejected from the bony socket.
Microleakage has been a key issue in the field of operative dentistry1, but it is not long since it has drawn the attention of orthodontists. From the orthodontic point of view, microleakage is an important factor in the development of two iatrogenic lesions particularly at the adhesive - enamel interface: white spot lesions and decalcification. The presence of fixed orthodontic appliances impedes oral hygiene and facilitates plaque accumulation. This in turn increases the bacterial counts in the plaque around the attachments and the production of organic acids2. In the presence of a low pH in the oral environment, the calcium and phosphate ions diffuse out of enamel resulting in demineralization and white spot lesions3.
