Filter by:Canine impaction is a sign of abnormal dental development with potentially far-reaching consequences (such as significant root resorption and loss of lateral incisors. This compromises both aesthetics and function of the teeth, making the prediction of canine tooth impaction increasingly important. Interceptive orthodontic measures, such as extraction of deciduous canines or molars or maxillary expansion aim to create extra space in the dental arch, allowing the canines to position themselves better and normalizing their eruption pattern. This study corresponds to the second phase of an RCT, based on the results of the first phase, published in July 2023 (S59030) (Willems G, Butaye C, Raes M, Zong C, Begnoni G, Cadenas de Llano-Pérula M. Early prevention of maxillary canine impaction: a randomized clinical trial. Eur J Orthod. 31;45(4):359-369). The first phase compared the effect of 3 interceptive strategies (expansion, extraction and no intervention) on the position of impacted maxillary canines, finding that maxillary expansion provides the most improvement on impacted canine position. In second phase, 8-year-old patients without posterior crossbite and lack of space in the dental arch are randomized to treatment with 'slow maxillary expansion with removable plates' or 'no treatment'. These groups are additionally compared with patients with a crossbite and lack of space, which always receive expansion treatment. All selected patients will be followed up for at least 18 months. The primary endpoint is to investigate the effect of maxillary expansion with removable plates on the position of maxillary canines prone to impaction during early mixed dentition, assessed on panoramic X-rays. The secondary endpoint is the assessment of the need for additional orthodontic treatment.
In this study, the postoperative clinical and microbiologic effects of chlorhexidine toothpaste and chlorhexidine-free toothpaste with the same content were compared after bilateral mandibular impacted third molar surgery. Similarly positioned fully impacted impacted lower third molars were extracted. Bilateral impacted wisdom teeth of the patients were randomly selected. After the operation, the experimental group received Dentasave 0.2% chlorhexidine toothpaste containing chlorhexidine and the control group received toothpaste with the same content but without chlorhexidine. Teeth were extracted by the same dentist at 14-day intervals. For microbiological analysis, saliva samples were taken before the first tooth extraction, before the second tooth extraction 14 days later and on the 28th day and sent to the microbiology laboratory. Wound healing, edema and trismus in both extractions were evaluated 1 week after tooth extraction. Wound healing was evaluated as good, acceptable and poor. VAS (Visual Analog Scale) was used for pain assessment and recorded 14 days after tooth extraction.
Assessment of SILKAM® suture material in mucosal closure in oral surgery (mucosal sutures). A prospective, monocentric, single arm observational study.
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.
