Active clinical trials for "Tooth, Impacted"

In the present study, the main hypothesis hypothesizes that the local application of melatonin in the post-extraction socket produces favorable differences in the immediate postoperative period, as anti-inflammatory, analgesic, and early osteogenic regarding the natural healing process of the socket.

The aim of this study was investigate the effectiveness of Local Antibiotic Applications With Platelet Rich Fibrin on Third Molar Surgery Outcomes In Vivo and In Vitro. The study included a total of 60 patients with impacted mandibular third molar. Patients were evaluated in 3 randomly separated groups. For the first and second group, Platelets Rich Fibrin+ local antibiotics were applied into the tooth socket. For the first group, amoxicillin was applied and for the second group, clindamycin was applied. There was a control group which only Platelets Rich Fibrin was applied into the socket. The outcome variables were pain, swelling, the number of analgesics taken, and trismus. These variables were also assessed based on first, second, third, and seventh days following the operation.

Research questions: Will the panoramic images derived from cone beam CT data give better diagnostic ability than conventional panoramic radiographs? Will 3D cephalometric analysis offer the orthodontists and surgeons better information for treatment planning? 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: The availability of the 3D cephalometric analysis influences the orthodontic and maxillofacial treatment plan and decision, and might change the treatment outcome. Panoramic images derived from cone beam CT data may provide equal information for diagnosis as conventional panoramic images. 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 aim of the study is to evaluate, wheather the sedation or general anesthesia in third molar extractions influence the patient's psycho-emotional status. It is believed that the type of anesthesia may influence not only the psycho-emotional status after the procedure, but also before the procedure.

the purpose of this study was to test the effectiveness of the envelope flap compared to trapezoidal flap in impacted mandibular third molar extractions.

The aim of this study was investigate the comparison of postoperative effects of local antibiotics mixed with platelet-rich fibrin and postoperative systemic antibiotic applications prescribed for mandibular impacted third molar tooth extraction. The study included a total of 75 patients with impacted mandibular third molar. Patients were evaluated in 5 randomly separated groups. For the first and third group, Platelets Rich Fibrin+ systemic Antibiotics were applied into the tooth socket and for the second and fourth group, Platelets Rich Fibrin + local antibiotics were applied, respectively. There was a control group which only Platelets Rich Fibrin was applied into the socket. The outcome variables were pain, swelling, the number of analgesics taken, and trismus. These variables were also assessed based on first, second, third, and seventh days following the operation.

In the everyday clinical practice the incidence of minor complications is approximately 15-20% of the total number of third molar removals. Alveolitis (dry socket syndrome) may arise in 30-40% of the surgical tooth removals. Several preventive approaches are known, such as the use of iodoform gauze, zink-oxide eugenol paste, platelet rich fibrin (PRF), different medicine containing pastes, like antibiotics containing, non-steroid pain killer containing, steroid containing, or the application of chlorhexidine gel and solutions. In the case of a manifest alveolitis these methods can be used as well. The aims of this research are: i) to identify the important pathogens which play role in the development of alveolitis (microbiological methods), ii) to analyze the in vitro effectivity of the different antiseptic materials in case of infections (inhibitory zones) iii) to compare the effectivity of different alveolitis preventive methods in a prospective clinical study, iv) to compare the different treatment options in alveolitis in a prospective clinical study.

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.

Thirty-eight patients were randomly divided into 2 groups; the intraosseous injection group of dexamethasone (4 mg) and the submucosal injection group. All surgeries were performed by one surgeon. Postoperative pain was evaluated by visual analog scale score immediately after surgery and on postoperative days 1, 3, and 7. Swelling (determined using two linear measurements) were assessed just before the surgery and on postoperative days 1, 3, and 7 by using a digital vernier caliper. Early healing of periodontal soft tissue wound was assessed by using Early Wound Healing Score (EHS) which composed of 3 parameters: clinical signs of re-epithelization (CSR), clinical signs of hemostasis (CSH), and clinical signs of inflammation (CSI) and were assessed on postoperative days 1, 7, and 14. Mouth opening (determined by measurement of the maximum inter-incisal distance) were assessed just before the surgery and on postoperative days 1, 3, and 7 by using a digital vernier caliper.

The study investigates the impact real output has on the adhesion of adhesives.
