Ph.D project: Periapical bone healing after apicectomy with and without retrograde root filling. The aim of this study is to assess periapical bone healing after apicectomy without a filling and apicectomy combined with a retrograde filling material, MTA. Further, we will estimate risk factors in non-healing cases. Study hypothesis: There is no difference in treatment outcome between: Periapical bone healing after apicectomy with retrograde root filling and Periapical bone healing after apicectomy without retrograde root filling
The effectiveness of local anesthetics is reduced if inflammation is present, making it difficult to control pain during such procedures as root canals and wisdom teeth removal. This set of studies will assess the effectiveness of the opioid (synthetic narcotic) fentanyl in enhancing the local anesthetic lidocaine (delivered with epinephrine) when used on inflamed molar teeth. In the first study, a topical anesthetic patch or a placebo will be placed on the gum tissues next to four or five lower posterior teeth. The patch will removed at either 5, 10, or 15 minutes. An electronic test that sends a light electronic impulse into the tooth, lip sensitivity testing ("Is your lip numb?"), and discomfort reports will be started immediately after removal of the patch and repeated every 5 minutes for 30 minutes. An oral surgeon will then remove the patient's wisdom teeth (tooth). In the second and third studies, a topical anesthetic will be placed on the gum tissue. An electronic test that sends a light electronic impulse into the tooth, lip sensitivity testing ("Is your lip numb?"), and discomfort reports will be started and done several times throughout the test. Then two small openings, one on each side of the tooth, will be drilled into the bony tissues surrounding the tooth. A narcotic drug fentanyl or a placebo drug will be delivered through these openings, allowing placement of the drug next to the nerves that are difficult to numb. Lidocaine, along with a small amount of epinephrine, will be delivered. An oral surgeon will then remove the patient's wisdom teeth or tooth (study 2) or do a root canal (study 3). In the fourth study, a topical anesthetic will be placed on the gum tissue. Then two small openings, one on each side of the tooth, will be drilled into the bony tissues surrounding the tooth. A narcotic drug fentanyl or a placebo drug will be delivered through these openings. Lidocaine, along with a small amount of epinephrine, will be delivered at one of three rates (15 patients for each rate). Blood pressure, heart rate, and breathing rate will be taken before the topical anesthetic patch is applied, 2 minutes after, and every 5 minutes for the next 45 minutes. Blood samples will be taken 6 times over the course of 60 minutes. When testing is complete, an oral surgeon will remove the wisdom teeth (tooth). One month later, blood samples will be taken using a different drug delivery method in order to compare results.
This study will examine the structure of the receptor molecule for the herpes simplex virus (HSV) and determine if the receptor's structure is related to susceptibility to infection with the virus. There are two types of herpes virus-HSV-1 and HSV-2. HSV-1 commonly causes cold sores, and HSV-2 usually causes genital herpes. The herpes virus enters (infects) cells through protein molecules on the cell's surface. This study will explore possible differences between the structure of the HSV receptor molecule in different people to understand better how infection occurs. The study will also look at proteins on white blood cells (Fc receptors, cytokines and mannose binding protein) that may influence the risk of infection with HSV. Information from this study may lead to new treatments to prevent HSV infection. People 18 years of age and older who are infected with HSV and people who are not infected with the virus may be eligible for this study. Participants will have blood drawn to confirm whether or not they have been infected with the virus. The blood sample will also be used to study the genes for the HSV receptor, Fc receptors, cytokines, mannose binding protein and related proteins on the white blood cells. No more than 40 milliliters (8 teaspoons) of blood will be drawn. Participants who are found to have antibodies to HSV-2 will be offered counseling and advice on practicing safe sex techniques to help prevent sexually transmitted diseases, including HSV-2 infection.
This study offers evaluation and treatment of patients with diseases of the mouth or systemic diseases that involve the mouth. The protocol is not designed to test new treatments; rather, patients will receive current standard of care treatments. The purposes of the study are: 1) to allow NIDCR's Gene Therapy and Therapeutics Branch staff to gain more knowledge about oral soft tissue diseases and possibly identify new avenues of research in this area; and 2) to establish a pool of patients who may be eligible for new studies as they are developed. (Participants in this protocol will not be required to join a new study; the decision will be voluntary.) Patients of any age with oral diseases or systemic diseases involving the mouth may be eligible for this study. Women of childbearing potential and women who are pregnant or breastfeeding will only have tests and procedures and receive medications that pose no greater than a minimal risk to the fetus. Participants will have a comprehensive dental and medical examination, including a physical examination of the head and neck. Additional tests and procedures that may be required for diagnosis and to guide treatment include the following: - Blood and urine tests - for routine laboratory studies, assessment of kidney and liver function, and detection of viruses, fungi, bacteria or parasites - Electrocardiogram - to record the electrical activity of the heart - Biopsies - to examine tissue under the microscope. The method and number of biopsies depends on the individual's specific condition and the tissue to be removed. For all biopsies a local anesthetic (lidocaine with or without epinephrine) is injected at the biopsy site. A punch biopsy uses a small sharp cookie-cutter instrument to remove a small (about 1/10- to 1/5-inch) piece of skin. An excisional biopsy uses a small surgical knife or scalpel to remove a piece of tissue, usually requiring some stitches to close the wound. - Diagnostic imaging - X-rays, photographs, or other tests as needed for diagnosis Treatments include tablets, injections and topically applied medications. All preparations are approved by the Food and Drug Administration and are commercially available. Patient follow-up may vary from one visit to intermittent visits over a number of years, depending on the patient's condition.
