Active clinical trials for "Tooth, Impacted"

The purpose of the study is to determine whether equal subanesthetic doses of racemic ketamine is equally effective on females and males after surgical removal of third molars

This study will examine whether bradykinin receptors are produced at the site of wisdom tooth extraction and if they contribute to the amount of inflammation and pain that follows surgery. Bradykinin is a molecule produced by enzymes at the site of an injury and then binds to receptors to cause pain. The study will also evaluate the role of genetic factors in the production of bradykinin and their receptors and the pain associated with minor surgical procedures. Patients between 16 and 35 years of age who are referred to the NIH dental clinic for removal of two wisdom teeth may be eligible for this study. Candidates must be in good health and must not be allergic to aspirin, non-steroidal anti-inflammatory drugs, sulfites, or amide anesthetics. They will be screened with a medical history and oral examination, including x-rays to confirm the need for wisdom tooth extraction. On the morning of surgery following an overnight fast, participants have a blood sample drawn to extract DNA for gene studies. Just before surgery, they are given an intravenous (IV) sedative to induce drowsiness and a local anesthetic to numb the mouth. They are also given IV either Ketorolac, a non-steroidal anti-inflammatory drug, or placebo, a look-alike medication with no active ingredient. After the extractions, a small piece of plastic tubing is placed in both extraction sites, and every 20 minutes for the next 3 hours inflammatory fluid is collected from the tubing for measuring chemicals believed to cause pain and swelling. Patients rate their pain by answering pain-related questions every 20 minutes. Patients who have pain that is not relieved by the study medication (Ketorolac or placebo) are given, upon request, 50 mg of the pain reliever tramadol (Ultram). Patients remain in the clinic for at least 3 hours and no more than 7 hours after surgery in order for monitoring the effects of the study drugs as the local anesthetic wears off. Patients undergo two biopsies during the study - one before and one after the extraction - to measure any changes in chemicals produced in response to the surgery. The second biopsy is done either 3, 7, or 24 hours after the extraction. Patients in the 3- and 7-hour groups are given a small dose of local anesthetic in the gum for the second biopsy and remain in the clinic until the biopsy is done; those in the 24-hour group are given forms to record pain ratings at home and return to the clinic the following morning for a 2-hour follow-up visit. All patients are given standard pain medication (flurbiprofen) to take at home.

The aim of this study was to compare the effects of lingually-based triangle flap design and buccally based triangular flap design on postoperative swelling, trismus pain after mandibular third molar surgery.

Surgical removal of impacted third molars is one of the most frequent procedures carried out in the oral and maxillofacial surgery clinics. There are a varying range of postoperative complications including pain, edema and swelling. Antibiotics, analgesics and mouthwashes are usually prescribed for the treatment of these complications. Patients undergoing impacted third molar surgery are frequently prescribed chlorhexidine mouthwashes with/without benzydamine hydrochloride. However, to preclude the adverse effects of these chemical agents, there has been a search for plant-derived alternatives with anti-inflammatory, antibacterial and analgesic properties as part of the oral care routine following surgical removal of impacted third molars. However, there is no study investigating the comparison of different essential oils in the literature. Thus, this multicenter study was aimed to evaluate the effects of St. John's wort oil and virgin olive oil on the postoperative complications and compared with chlorhexidine gluconate plus benzydamine hydrochloride mouthwash after the removal of impacted wisdom teeth.This study was aimed to evaluate the effects of St. John's wort oil, virgin olive oil, and chlorhexidine gluconate plus benzydamine hydrochloride on the postoperative complications after the removal of impacted wisdom teeth.

Impacted canine causes many problems for patients, such as damage to the adjacent teeth roots, effects on gingival tissues, aesthetic problems, difficulty, and prolonged orthodontic treatment duration. Therefore, solutions to accelerate the movement of impacted canines with the help of surgical procedures to reduce treatment time will be investigated, such as intra-operative alveolar perforations and piezocision. We also aimed to evaluate periodontal changes associated with such accelerating procedures compared with the conventional traction method.

This is a single centre, three-arm randomised, double-blind, double-dummy, parallel group, single-dose, active and placebo-controlled efficacy and pharmacokinetics/ pharmacodynamics study to evaluate the efficacy and safety of 2 x 200 mg Ibuprofen Liquid Capsules in subjects with post-operative dental pain.

The main objective of the present study was to evaluate the effects of different preoperative information techniques (verbal, written, video with background audio, and silent video with subtitles) on patients' anxiety levels before and after third molar extraction. The secondary objective was to determine the superiority of the information methods evaluated over each other. We hypothesized that the information provided by video with or without background audio would decrease preoperative and postoperative anxiety levels more effectively than information provided by verbal and written methods.

The aim of this clinical trial is to investigate and compare the effect of piezoelectric surgery on tissue, cellular and molecular level of oral surgical wound healing and postoperative outcomes (pain, swelling, trismus) after lower third molar surgery in healthy patients

Permanent canines in the maxilla usually erupt into the mouth at 11-12 years of age. In approximately 2% of the Swedish population they fail to erupt, and are then referred to as impacted. One severe complication of impacted maxillary canines is damage (root resorption) to the roots of adjacent teeth. The root resorption may be so severe that neighboring teeth are lost. If the impaction is detected early (at 9-10 years of age), the recommended treatment is to extract the deciduous canine, to help the permanent canine to resolve its unfavorable position. If there is no improvement of the position of the canine 1 year after the extraction, surgical and orthodontic treatment is indicated. Surgical exposure is followed by orthodontic treatment with fixed appliance for 2 to 3 years to bring the canine into correct position. Two different main principles of surgical exposure in palatally impacted maxillary permanent canines are the so called closed versus open surgical techniques. Closed technique involves surgically uncovering of the canine with a mucoperiosteal flap dissected off the bone. The bone covering the canine is being removed and an attachment with a chain is bonded to the tooth. The flap is repositioned and sutured back with the chain above the mucosa. Shortly after the surgery, orthodontic force is applied via the chain. The canine is orthodontically moved beneath the palatal mucosa by forced eruption. Open technique involves surgically uncovering of the canine, removing a window of tissue around it and placing pack to cover the exposed area. Then the treatment approaches vary depending on whether the attachment with a chain is bonded to the exposed tooth at surgery or if spontaneous eruption of the palatally impacted canine is expected postsurgically. In both alternatives orthodontic force is applied via the chain and the canine is orthodontically moved above the mucosa. These two techniques of surgical exposure of palatally impacted canines seem to be the two routinely used in Sweden. The purposes of this study are to examine, describe and compare the treatment outcomes in regard to success and duration of treatment, complications, side effects, cost-benefit aspects and patients´ perceptions in closed versus open surgical exposure techniques, in cases with palatally impacted canines. The objective is to test the null hypothesis that there are no differences in the above outcomes between open or closed surgical exposure of palatally impacted canines.

This study is testing the safety and effectiveness of acupuncture in controlling pain related to the removal of partially impacted mandibular third molars. Acupuncture is the Chinese art of healing by inserting needles into the skin. Participants ages 18 - 40 are given an initial x-ray to determine if one lower molar is partially bony impacted. Eligible participants will then undergo standard oral surgery to remove the impacted molar. A local anesthetic will be used prior to surgery. Directly after surgery the participant will be assigned to one of three groups. Participants will not be able to select which group they are assigned. Participants will receive either real or sham (fake) acupuncture as a treatment for post-extraction pain. After the initial acupuncture treatment, participants are required to remain for six hours at the dental site to be monitored. If a participants discomfort is measured as moderate or higher then a second acupuncture treatment will be administered. All participants will be administered questionnaires during the day of surgery. Participants will also be required to complete two diaries during the seven days following surgery. On the seventh day, participants return to have stitches removed and hand in completed diaries.
