Filter by:This study evaluated the effectiveness of the Erythrina mulungu in controlling anxiety in patients undergoing bilateral extraction of asymptomatic, impacted mandibular third molars.
To test the null hypothesis that there are no differences in the OHRQOL and clinical outcomes in patients undergoing palatal canine disimpaction using either open or closed surgical method.
Background: - The third molars (wisdom teeth) normally grow in during late adolescence or early adulthood. Many people need or choose to have these teeth removed with oral surgery. Normally, the removed teeth and tissue are thrown away as medical waste. However, oral health researchers want to collect the teeth and tissue for research. They also want to encourage dentists at the National Institutes of Health to improve their skills in oral surgery. This study will collect the teeth and tissue of people who need to have oral surgery to remove their wisdom teeth. Objectives: - To provide continued dental skills training for dentists at the National Institutes of Health. - To collect teeth and tissue samples following wisdom tooth removal surgery. Eligibility: - Individuals between 16 and 50 who need to have their wisdom teeth removed. Design: - This study will involve a minimum of three visits. There will be a screening visit, a surgery visit, and at least one follow-up visit. - Participants will be screened with a physical exam and medical history. A full dental exam with x-rays will be given to evaluate the need for surgery. - At the second visit, participants will have oral surgery to remove their wisdom teeth. The teeth and tissue removed during the surgery will be collected for study. - Participants will receive drugs to control the pain after surgery. They will also be able to contact a dentist if there are any problems. - Between 7 and 21 days after surgery, participants will have a followup visit to check the healing. If they are having no problems, this will be the last visit. If there are any postsurgery issues, they will be scheduled for additional visits as needed.
Maxillary canines are the second-most frequently impacted teeth in the dental arch after the third molars. The suspicion of a maxilary canine impaction raises with the absence of the permanent canine in the arch after the normal period of eruption, and has to be confirmed by a clinical evaluation of the patient and a radiographic assessment. The approaches to the management of impacted canines are many, but the preferred approach typically involves surgical exposure and guided orthodontic eruption. The initial mechanical eruption can be achieved in several ways, but an important distinction has to be done according to the anchorage method. The aim of this study is comparing Temporary Anchorage Devices (TADs), and cantilevers with a TMA sectional, using the quantification of canines and molars displacement as the main parameter. A TAD is a mini screw temporarily fixed to bone for the purpose of enhancing orthodontic anchorage either by supporting the reactive unit (the anchoring tooth) or by obviating the need for it at large, and is subsequently removed after use. The mini screw employed in this clinical trial will be an alloy type IV titanium screw with 1.5mm diameter and 8-10 mm long, and under local anesthesia will be placed in an area between the first premolar and first molar, on the buccal or labial side according to the canine position and teeth position. For the evaluation of the canines and molar displacement, two CBCT will be required: the first one before the beginning of the traction (T0), the second one after three months (T1). Both the CBCT will be imported in the MIMICS image processing software (Materialize Group, Leuven, Belgium). Limiting the tissue density ranges and restricting the anatomical area of interest, a cropped colored mask will be obtained from each CBCT. Then the co-registration, through the identification of 5 at least landmark points, will allow the overlap of the two masks. At this point, calculating the 3D surface models, the tooth pre- and post-treatment positions will be evident and the measurement of the displacement possible.
The purpose of this registry is to record information and evaluate the impact of Endoscopic Ultrasound (EUS) Guided Endoscopic retrograde cholangiopancreatography (ERCP) on the management of pancreatico-biliary disorders. The registry will evaluate efficacy, safety and technical success of the Endoscopic Ultrasound (EUS)Guided Endoscopic retrograde cholangiopancreatography (ERCP) procedures. The safety and efficacy of various EUS-Guided ERCP procedures have been assessed in a series of studies. This multi-center registry has been initiated: - To document the impact of EUS-Guided ERCP procedures on the management of pancreatico-biliary disorders including malignancies. - To assess the clinical and technical success rates of EUS-Guided ERCPs for diagnostic or therapeutic procedures. Design is retrospective and prospective registry study. Procedures that will be captured include: 1. EUS-Coils placement 2. EUS Glue injection 3. EUS-Fiducial placement 4. EUS-Neurolysis 5. EUS-Stent placement 6. EUS-alcohol injection 7. EUS-fluid collection, abscess or cavity drainage 8. EUS guided ductal drainage 9. EUS-guided Ablation 10. EUS-guided anastomosis 11. EUS Guided ERCP for gallbladder, pancreatic duct or biliary duct drainage
Ginger contains constituents with pharmacological properties similar to the novel class of dual-acting NSAIDs. Compounds in this class inhibit arachidonic acid metabolism via the cyclooxygenase (COX) and lipooxygenase (LOX) pathways. These compounds have notably fewer side effects than conventional NSAIDs and now are being investigated as a novel class of anti-inflammatory compounds. Although ginger has potentially strong anti-inflammatory components, its efficacy on acute inflammation was not assessed before. The common postoperative sequelae of surgical removal of impacted teeth are pain, trismus and swelling, related to local inflammatory reaction, with cyclooxygenase and prostaglandins playing a crucial role. NSAIDs (e.g. Ibuprofen) are effective in the management of postoperative dental pain, likely through blockage of prostaglandin synthesis and are commonly used. The efficacy of Ibuprofen in the treatment of postoperative dental pain has been evaluated in several clinical trials. However, NSAIDs are contraindicated in patients with gastrointestinal ulcers, bleeding disorders, and renal dysfunctions. Therefore, there is a need for an effective, oral analgesic with a more favorable safety profile. The primary aim of this study was to investigate the ability of Ginger powder (Zintoma, Goldaru) to reduce postoperative swelling, pain and trismus in an acute pain model.
The purpose of this study is to evaluate the analgesic efficacy of a single intranasal (IN) administration of ketorolac after dental impaction surgery.
Research questions: 1. Will the panoramic images derived from cone beam CT data give better diagnostic ability than conventional panoramic radiographs? 2. Will 3D cephalometric analysis offer the orthodontists and surgeons better information for treatment planning? 3. Will the 3D cephalometric analysis give more accurate treatment plan and better treatment outcome? General hypothesis and special aims Overall aims: - To compare 2D versus 3D cephalometric analysis: treatment planning and therapeutic outcome. - To determine the accuracy and diagnostic ability and usability of the 3D cephalometric analysis. - To evaluate the diagnostic ability and usability of the panoramic image derived from cone beam CT data as compared to 2D panoramic images. - To evaluate the value of the cone beam CT data in cephalometric analysing process for orthodontic and maxillofacial surgery treatment. Hypotheses: 1. The availability of the 3D cephalometric analysis influences the orthodontic and maxillofacial treatment plan and decision, and might change the treatment outcome. 2. Panoramic images derived from cone beam CT data may provide equal information for diagnosis as conventional panoramic images. 3. Cone beam CT will be able to replace "classic orthodontic imaging" being more time and dose efficient and having a beneficial effect on treatment outcome.
The purpose of this pilot clinical trial is to evaluate whether alveolar-decortication has the potential to reduce orthodontic treatment time following surgical exposure of palatally impacted canines.
The purpose of this investigation is an exact preoperative 3D-localisation of impacted and supernumerary teeth in the maxilla using Cone Beam Computer Tomography
