Filter by:The purpose of this study is to compare two different timings of restoring dental implants that are placed right after tooth extraction: The test group will have the provisional crown placed at the time of implant placement. The control group will have the tooth removed and the implant placed at the same appointment but restorations placed after 4 months. Both procedures currently are accepted methods for replacing missing teeth but direct comparisons of the two procedures are lacking. The results of this study should aid clinicians in selecting the best timing for restoring implants for their patients. The hypothesis is that immediate restoration might increase aesthetic outcomes, e.g. less mucosal recession.
The Charcot syndrome Marie Tooth is the most frequent hereditary neuromuscular diseases: there is no curative treatment at present, on the other hand precautionary measures can be taken (physiotherapy, port of splints, orthopaedic surgery and technical assistants). In the literature and in our recent study (evaluation of the pain in the disease of CMT - Reference center of the neuromuscular diseases - CHU Bow) the frequency of the pain is important varying from 66 to 96 % cases, affecting especially hands and lower limbs. The care of the pain in the Charcot syndrome Marie Tooth is not codified. The transcutaneous neurostimulation(TENS) is a not medicinal and not invasive therapeutics, without any brought back collateral effect, used at the same time in the chronic pain and acute since 1960, as well for the neuropathic pains that musculo-scrawny. No study was realized this day on the use of the TENS with analgesic aim in the CMT. We suggest studying the analgesic efficiency of the TENS in the Charcot syndrome Marie Tooth on the pains of lower limbs, the most frequent painful location in our recent works. The main objective will be to analyze the improvement of the pain of lower limbs, based on the decrease of the analogical visual scale(ladder) (EVA), at least 30 %. The secondary objectives will be to estimate repercussions on the functional capacities ( ONLS), the quality of life (SF(sci-fi) 12), the satisfaction (EVA), the global impression(printing) of change ( PGIC), the consumption of analgesic, DN4, NPSI (Neuropathic Pain Symptom Inventory), Concise Questionnaire of the Pains ( QCD), HAD (Hospital Anxiety and Depression scale).
Both methods tested in this study disinfect the non-vital root canals and induce blood clot formation inside the root canal. One method places calcium hydroxide inside the root canal after disinfection and the blood clot is induced four weeks later. The other method performs disinfection and induction of blood clot in one appointment. The investigators hypothesize that both methods will obtain the same success rate in eliminating infection, increase in root length and canal walls thickness.
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.
This exploratory cross-sectional study proposes, firstly, to objectify in a population of Charcot-Marie-Tooth disease type 1A (CMT 1A)if there is a correlation between the recording of electrical parameters and upper limb muscle strength of the thigh and in a second step, to seek a relationship between the measured parameters.
Integration success rates and the preservation of crestal bone will be higher for the experimental device than for the control implants.
Integration success rates measured by lack of implant mobility and crestal bone regression measurement will be higher for the experimental implant design than for the control implants.
Integration success rates measured by resistance to countertorque testing will be higher for the experimental implant design than for the control implants.
A study where dental implants with different roughened surfaces will be evaluated for the ability to resist countertorque forces.
This study will demonstrate the benefits of platform switching design of the Osseotite dental implant.
