View clinical trials related to Impacted Third Molar Tooth.
Filter by:The goal of this clinical trial is to investigate the hypothesis that there are none difference in the treatment result of orthognathic surgery on the lower jaw, with interoperative wisdom tooth removal rather than preoperative wisdom tooth removal. In patients with severe dental malocclusion combined with a dentofacial deformity. The main question it aims to answer are: • Is there a difference in the degree of complication and the patient's perception, with inter-operative wisdom tooth removal rather than pre-operative wisdom tooth removal. Participants will be will be divided into two groups, with one group having their wisdom teeth removed 6 months before their jaw moving surgery and the other group having their wisdom teeth removed in connection with their jaw moving surgery.
The objective is to compare the sagittal and vertical skeletal parameters of patients with an impacted third molar. Patients will be analyzed according to their skeletal characteristics: skeletal class (sagittal direction) and facial skeletal typology (vertical direction). The inclusion characteristics of third molars will also be analyzed, to see the links between typology and inclusion. The principal hypothesis is no significant difference in third molar inclusion patterns in relation to skeletal divergence.
The investigators aim to investigate if the additional information available from a 3D scan of the wisdom tooth can reduce the risk of nerve injury during wisdom tooth surgery compared to conventional 2D images. Wisdom tooth surgery is a common surgical procedures that a significant proportion of the population will undergo. As with any other surgical procedure, there are potential complications, of which, injury to the nerve supplying feeling to the lip, chin, and tongue is the most significant. This can lead to persistent pain, tingling, or numbness that may impact a patient's ability to eat and function. The risk of nerve injury during wisdom tooth surgery is assessed using X-ray images, which show the position of the nerve and tooth in the jawbone. 2D and 3D scans are used, which have their own advantages and disadvantages such as reduced cost and radiation dose with 2D or more information from 3D images, but it remains unclear which is better at reducing the risk of nerve injuries.
A comparative analysis of the effectiveness of the erbium laser with the wavelength of 2.94 µm and traditional instruments in the extraction of the impacted lower third molars will be performed. Clinical, radiological and biochemical findings will be assessed after extraction of the impacted lower third molars.
Project summary The surgical removal of mandibular third molar is one of the most common procedures done in oral and maxillofacial surgery. Patients often experience pain, swelling, trismus, dehiscence, alveolar osteitis, infection, nerve injury and periodontal tissue damage after third molar surgery. Flap design is an important step in third molar surgery.The aim of this study is to compare the triangular and envelope flap designs in lower third molar surgery in terms of postoperative sequelae including pain ,trismus,swelling,incidence of dry socket and also operative time taken.The study also aims to find out does the level of impacted mandibular third molar and number of roots has effect on postoperative outcomes in surgical removal of mandibular third molar.The study design used will be a double-blind randomized clinical study. Patients who fit the inclusion criteria will be included as research subjects.Sample will be divided into two groups randomly. In one group the envelope flap will be raised during surgical removal of the lower third molar while in the other triangular flap will be used. Investigators will also divide the third molars into level 1,level 2,level 3 based on the relationship between the tip of mesial cusp of impacted third molar and the distal surface of crown of adjacent second molar based on orthopantomograph findings.Level 1 will be when the tip of mesial cusp of third molar is within the occlusal third of crown of second molar,level 2 will be when the tip of mesial cusp of third molar is within the middle third of crown of second molar, level 3 will be when the tip of mesial cusp of third molar is within and below the cervical third of crown of second molar. Another subgroup will be based on the number of roots of the impacted third molar where investigators will divide the third molar into single rooted and multirooted based on orthopantomograph findings. Investigators will also divide the sample based on gender and age group as below 30 years and above 30 years. The primary outcomes to be measured are pain and operative time while secondary outcomes are swelling ,trismus and incidence of dry socket.Outcome assessment will be done by another clinician than surgeon using scientific tools and techniques as mentioned. Surgical procedures and outcomes measurement will be done by separate clinicians to ensure masking.
Accuracy of the variables used in Wharfe assessment and Pederson difficulty index for impacted mandibular third molar surgery. The lower 3rd molar tooth is one of the most frequently impacted teeth. Its prevalence ranges from 30.3% to 68.6% worldwide according to a study conducted by Sekhar, 2020. The impaction of a tooth can be defined as a pathological condition in which eruption of tooth is not normal i.e. it is not erupted as expected within a specific time period. The impaction renders the affected tooth as non-functional due to its postural instability/ abnormal position. The normal tooth eruption is dependent on several local as well as systemic factors. Normal eruption can be altered by neighboring tooth, excessive soft tissue in the surrounding, or the dense overlying bone. Race and Ethnicity an also affect/ alter the impaction rate. The removal of 3rd mandibular molar/ wisdom tooth is one of the most commonly performed surgical procedures, being done in dental clinics on daily basis. To predict the difficulty level of this procedure for impacted lower 3rd molar, no scoring system/ scale is considered sufficient i.e. every scale takes some factors into account, while missing some factors, so clinically not very much reliable. Some of the proposed scales/ models which are clinically in use are as follows: WHARFE's, Pederson's, Winter's, and Pell and Gregory's model.
The tooth of the patient who applies to the clinic for the impacted wisdom tooth will be classified according to Escoda's difficulty classification. Before the extraction, patients' interincisal, tragus-commissural, and lateral canthus-angulus distances, Oral Health Impact Profile -14 (OHIP-14) scores, and serum levels of CRP and D-Dimer will be measured. Operation time will be recorded. After the operation, on 4th-day patients' patients' interincisal, tragus-commissural, and lateral canthus-angulus distances, Oral Health Impact Profile -14 (OHIP-14) scores, and serum levels of CRP and D-Dimer and Visual Analogue Scale (for pain) scores will be measured and recorded. On the 10th day, all these measurements will be repeated. All recorded data will be evaluated for possible correlations based on extraction difficulties.
A clinical study to evaluate the efficacy and safety of a mouthwash containing Hydrogen Peroxide, Sodium Hyaluronate and Glycine in the healing of post-extraction sites of wisdom teeth by film forming action.
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.
