Anesthesia when dental care
Cause of the failure of local anesthesia when dental care | dmatxi.com. Before performing extractions should be done first local anesthetic. In general, given a local anesthetic, but in certain circumstances general anesthesia performed by anesthesia specialists. Local anesthesia is divided into 3 different types of anesthesia, that is topical anesthesia, infiltration anesthesia, and anesthetic blocks.
Topical anesthetics are used for pain relief at the surface, because the touch only the ends of nerve fibers. Materials used in the form of salf. Meanwhile, infiltration anesthesia is anesthesia performed in children for the maxilla or mandible. Easily workable and effective. Penetration power of infiltration anesthesia in children is quite deep, as the composition of bone and tissue has not been so compact. And block anesthesia is anesthetic used for permanent molar tooth extraction.
Understanding of local anesthesia
Local anesthesia is an action for temporary relief of pain in one part of the body by applying a topical or injection materials without losing consciousness. Prevention of pain during dental procedures can establish a good relationship between dentist and patient, build trust, eliminate fear, anxiety and demonstrate a positive attitude from the dentist. The technique of local anesthesia is a very important consideration in the treatment of pediatric patients. Terms of age, a topical anesthetic, and analgesic injection techniques can help patients gain a positive experience from a local anesthetic. Child’s weight should be considered to minimize the possibility of toxic reactions and the length of working time anesthetics, because it can cause trauma to the lips or tongue.
Anesthesia or an act of relieving pain while performing surgery and other procedures that cause pain in the body. Anesthesia is also done at the time to tooth extraction to relieve pain during the process of repeal by using local anesthesia. Failure of local anesthesia at the time of extraction or dental care may have occurred due to several causes. Failure of local anesthesia can be caused by several factors, this is of course very detrimental.
1. Variations in anatomy
Local anesthetic is always effective if injected in the right anatomical regions and given sufficient time to work. Stunning work by blocking the nerve supply to certain areas under the influence of drugs. But in some people found an unusual neurological condition, so common ways used by dentists will not work with the maximum. More anesthesia is needed to tackle these problems and injected a different place to block the more leverage against the tooth.
This unusual anatomy can be a problem with the lower jaw, because here the dentist to use nerve blocks as opposed to infiltration in the upper jaw. this is because the nerve runs in jaw different upper and lower jaw. The nerves of teeth in lower jaw found in dense bone in the maxillary nerve while there on the surface before getting into gear. Maxillary more poreous which means that when the anesthetic is injected next to the teeth, can be connected with the root, making the teeth will be numb. More dense and lower jaw in addition to dental injections is usually not enough to make the tooth numb.
The reason some people can not be anesthetized with either on the lower jaw is due to the opening of the canal is not in the usual place, so it requires a different method than usual to overcome it.
Anxiety will cause a local anesthetic did not last long or too quickly exhausted. When someone is stressed or anxious, a local anesthetic may not work as when you relax. Hormones associated with anxiety (such as epinephrine or adrenaline) can prevent a local anesthetic works well in some people. Effect of local anesthetics may be delayed, or perhaps too quickly lost. Therefore, you better not anxious or stressed when it comes to the dentist.
3. The presence of infection or abscess
The presence of infection or abscess on gum can prevent a local anesthetic is working effectively, so it’s better to focus on the treatment of such infections. That’s why your teeth should not be revoked if the problem still occurs on the gum or soft tissue (ill or have an infection). Because the anesthetic will not work to work optimally on the gum that infections.
4. Errors of dentists in the delivery of anesthesia
Some dentists sometimes have an error in the inject anesthetic. but this is rarely a problem because it will be tested against the anesthetized area, if the anesthetic does not work, the injection can be a different place. So, As a patient at the dentist should ask if you are still ill? answer honestly do not underestimate the detained or discomfort during the test, because it would be very disturbing and dangerous at the time of tooth extraction or dental care.
5. Patients who are resistant to the drugs given
Causes of failure in local anesthesia can also be caused by patients who are resistant to the effects of certain local anesthetics. To overcome this problem is to use a different LA solution. This is cause of the failure of local anesthesia when dental care.
