Active clinical trials for "Tooth, Impacted"

The present clinical trial randomized will be to assess the link between the different haplotypes of CYP2C8 and CYP2C9 genes and the clinical efficacy of ibuprofen after lower third molar extractions. Onset, duration of postoperative analgesia, duration of anesthetic action on soft tissues, intraoperative bleeding, hemodynamic parameters, postoperative mouth opening and wound healing at the 7th postoperative day were evaluated. For this purpose, 200 healthy volunteers underwent removal of one lower third molar, under local anesthesia with articaine 4% (1:200,000 adrenaline) will be genotyped and phenotyped for these genes and their postoperative records with all data collected will be compared with the haplotypes found in the Brazilian population.

TThis is a comparative clinical study which will be conducted in OMFS department of DIKIOHS, DUHS Ojha Karachi. In this study the investigators will be comparing the effect of dexamethasone on pain and edema when administered pre-operatively vs post-operatively following surgery of impacted lower 3rd molars. Time duration of this study will be 2 months. A total of 100 patients will be considered in this study which will be equally divided into two groups; group A and group B (50 in each group).Group A will receive dexamethasone 1 hour pre-operatively while group B will receive the same post-operatively. All surgeries will be performed by the same maxillofacial surgeon and duration of surgery will be around 30-45 mins.

Clinical and preclinical studies have demonstrated encouraging results of non-steroidal anti-inflammatory drug (NSAID) chronotherapy in the management and treatment of inflammatory diseases such as rheumatoid arthritis. However, no previous clinical trials have addressed how the timing of NSAID administration within the day affects pain and healing outcomes after oral surgery that involves bone removal, such as surgical extraction of the third molars. Methods to address our aim, Single-center double-blind randomized controlled trial study design has been adopted. Patients who needed a lower third molar extraction and meet the eligibility criteria will be recruited. Participants will be randomized into two groups. Subjects in group one will be instructed to take an NSAID (ibuprofen 400 mg) at 7 AM and 12 PM combined with a placebo before bed between 8 and 10 PM for three days postoperatively. Subjects in group 2 will be instructed to take an NSAID (ibuprofen 400 mg) between 7 AM, 12 PM and between 8 and 10 PM for three days postoperatively. The patients' self-reported pain in the three days after surgery will be recorded as the primary outcome. Additionally, healing indicators such as the maximum interincisal distance and measurements of facial swelling will be recorded preoperatively and four days postoperatively. Each participant's blood level of C-reactive protein will be recorded pre- and postoperatively as an inflammatory marker. Discussion: The study will estimate the effect of using NSAID only in the morning following surgical extraction of the third molar to decrease pain and improve postoperative healing and recovery in comparison to the routine use of NSAIDs three times per day.

Cross sectional observational study to assess the feasibility of using the functional prototype of the restful jaw support device to support the jaw when extracting mandibular 3rd molars using moderate/deep sedation. An additional meeting(s) will occur, after the oral and maxillofacial surgeons (OMS) have completed all treatment procedures utilizing the device and surveys are completed, to provide feedback on how the device performed.

Seventeen patients diagnosed with the extraction-based treatment of impacted maxillary canines will be included in this study. Each patient will undergo conventional 2D radiography including panoramic, and lateral cephalometric, in addition to 3D imaging by cone beam computed tomography (CBCT) images. A set of variables will be evaluated on 2D and 3D images by a panel of assessors and then these results will be compared with the gold standard which will be established based on surgical detection and direct visualization of the impacted canine.

A digital workflow was used to assist the oral surgeon in pre-orthodontic exposure of a vestibular impacted canine using Augmented Reality. Through software for the Object Recognition and Tracking, the researchers expand reality with cone beam computer tomography digital contents to optimize the outcome of surgery. The real-time video frames of the operating field aligned with the three-dimension file of the impacted tooth, were used as a guide to evaluate the surgical access to perform a minimally invasive flap and osteotomy.

Ectopic eruption may be defined as the eruption of a permanent tooth that takes place in such a manner that a partial or a total resorption of the root(s) of an adjacent primary tooth occurs and can be noted during routine dental radiographic evaluation. It is a common case in mixed dentition and is usually diagnosed by a pediatric dentist. This retrospective study aimed to determine the prevalence and related factors of the ectopic eruption of permanent first molars(PFM). This retrospective study was performed using the panoramic radiographs of 11,924 child patients aged 6-10 years with at least one ectopically erupted PFM were included. The total prevalence of ectopic eruption, type, age, gender, jaw distribution, and bilateral versus unilateral occurrence were determined. The angulation of PFM, mesialization ratio of PFM, and degree of adjacent primary second molar(PSM) tooth root resorption were also assessed. The chi-square test, ANOVA was used for statistical analysis. A total of 76 ectopic eruptions were detected in the maxilla, 6 in the mandible, and 2 in both the maxilla and the mandible. In terms of the eruption status of cases with ectopic eruption, 27 were self-corrected, 51 remained impacted, and 6 were both. The impaction rate of the right upper PFMs was higher than that of others. No significant relationship was found between eruption status and degree of resorption. As a conclusion, small impaction of the PFM does not mean that the PSM lesion is also small. With substantial displacements, a proportionally diminutive lesion can exist, and vice versa.

Clinical evaluation of osteointegration of bone level implants (Stark conical screw implants, with V-Blast surface treatment), placed without sufficient primary stability.

The purpose of this investigation is an exact preoperative 3D-localisation of impacted and supernumerary teeth in the maxilla using Cone Beam Computer Tomography

The aim of this study is to get a clear view on current practice of surgical third molar removal in Belgium and the association with morbidity and complications. For this prospective cohort study, patients who visit the outpatient department of Oral and Maxillofacial Surgery of the University Hospitals Leuven or hospitals affiliated with the Flemish Hospital Network will be participating. All included patients are referred from primary dental providers for the surgical removal of one or more third molars. Before participating, written informed consent will be recorded from all eligible subjects. Patients consult one of the oral and maxillofacial surgeons or residents working on the department of the University Hospitals Leuven for the removal of third molars. In the standard procedure, patients are not routinely clinically monitored after one week at the department. Pre-operative, operative and postoperative data will be collected through a questionnaire, extracted data from the patient's medical file and panoramic radiography. The surgeon's individual operation technique will be registered through a one-off questionnaire. The questionnaires are taken at the same time of consultation and includes a maximum of 8 questions per time and are considered as non-invasive and a minimal burden for the patient. Postoperatively, patients record their recovery status and ability to resume daily- and work activities at day 3 and 10 by using a dairy system and, if necessary, revisit the outpatient department of oral and maxillofacial surgery.
