Filter by:Distal surfaces of second molars adjacent to wisdom teeth are always at risk for caries and external root resorption. The incidence of caries is high, especially in partially impacted third molars in mesioangular and horizontal positions. In this study, investigators aimed to examine the caries correlation in the distal second molar with the age, gender, side and DMFT scores of the participants.
This is a study about the dynamics and effects of different types of blocks (intraoral conduction anesthesia of the alveolar nerve and extraoral US block of the mandibular nerve) for extraction of lower third molars.
This research assesses removal of mandibular third molars by the lingual split technique with using Walter's lingual retractor for retracting lingual flap, and evaluates the lingual nerve injury that may result after applying this technique. The research sample included 20 patients and their age under 25 years where the grain is clear. The lingual nerve is assessed by sensory neurological tests on a graphic map that divides the tongue into sextants.
Many factors cause third molars to stay impacted in the jaws, hence the extraction of impacted wisdom teeth occurs often in dental clinics. Pain, trismus, and edema are typical postoperative complications following third molar surgery. Various strategies have been developed to prevent or reduce these postoperative complications, Among these is the use of Low-Level Laser Therapy (LLLT), which demonstrates numerous benefits in lowering pain, trismus, and edema by managing inflammation. The precise biological mechanism of action remains unknown. There seems to be evidence that it may have neuro-pharmacological impacts on the production, metabolism, and release of a number of biological compounds, the other option is use of ozone which has antimicrobial effectiveness (viricidal, bactericidal, and fungicidal). Additional well-known advantages include immunological modulatory and stimulating actions, including anti-inflammatory, biosynthetic, anti-hypoxic, and bioenergetic characteristics. Ozone can interact with blood components in the right amounts to positively impact oxygen metabolism and cell energy while also triggering antioxidant defense mechanisms
The time required for orthodontic traction of impacted canines after surgical exposure is a particularly troubling clinical problem because it prolongs the orthodontic treatment duration. During traction process, several complications could result in alveolar bone loss, root resorption of the adjacent teeth, ankylosis, discoloration, loss or vitality and gingival recession. Accordingly, and due to the lack of studies concerned with accelerating the traction movement of the impacted canines, we conducted this study to evaluate the effectiveness of some surgical interventions (corticotomy and Piezocision) in increasing the rate of orthodontic traction movement. We also aimed to evaluate dentoalveolar changes associated with the use of such accelerating procedures compared with the conventional traction method.
The aim of this study was to compare the conventional coronectomy and the combined coronectomy technique with vital pulp treatment. The primary outcome of the study was to evaluate the success rates of two treatment techniques based on clinical and radiologic observations regarding inferior alveolar nerve injury, root exposure and formation of periapical lesion. The secondary outcome was to evaluate the change in periodontal condition of the second molar adjacent to the operation area, dentin bridge formation and root migration. Between March 2018 and February 2022 eligible patients attended University Hospital for the removal of lower third molar with risk of inferior alveolar nerve (IAN) damage invited to the study. 60 teeth meeting the inclusion criteria in 52 participants were randomized to Test (with BiodentineTM, n=30) and Control (without BiodentineTM, n=30) groups. Neurological injury and post-operative pain were clinically evaluated at 12th months and 1st week, respectively. Root migration, dentin bridge formation and periapical lesion development were evaluated using Cone Beam Computed Tomography (CBCT) at 12th month. The change in the periodontal status of second molar was evaluated by measurement of pocket depth at 1st, 3rd and 12th months and the distance between base of the bone defect and the marginal crest and cemento-enamel junction and at 6th and 12th months month.
The present study proposes to compare the effect of a single preoperative dose of prednisone versus placebo in terms of facial swelling, trismus and pain after surgical removal of the mandibular third molar (M3M) in a split-mouth randomized controlled clinical trial.
Objectives: This study aims to evaluate the effects of A-PRF+ on postoperative pain, swelling, and trismus after surgical removal of impacted mandibular third molars. Method and Materials: A randomized controlled trial with a parallel design was performed on healthy patients with 76 impacted mandibular third molars with similar difficulty level, having needs and indications for extraction. All patients had the same standardized extraction protocol at the Department of Minor Oral Surgery of the National Hospital of Odonto - Stomatology in HCM City. In the study group, patients' blood was collected and centrifugated to produce A-PRF+, then placed in the wisdom tooth sockets after surgery. In the control group, the tooth sockets were curetted and sutured as in standard protocol. Pain value was assessed according to the VAS at 2, 4, and 6-hour time points after patients' lower lips stopped feeling numb, and on the 1st, 3rd, and 7th postoperative day; Swelling was evaluated based on the measurement between facial landmarks; Trismus was assessed based on the distance between incisal edges of upper central incisor and lower incisor during maximum mouth opening on the 3rd and 7th postoperative days. Data obtained were statistically analyzed.
This single-center prospective cohort study includes patients aged 18-30 years aimed to compare the effects of bilateral extraction of wisdom teeth at a single appointment (Group A) versus two separate appointments (Group B) on patients' oral health-related quality of life (OHRQoL). The primary outcome is Oral Health Impact Profile 14 score, while secondary outcomes included postoperative pain and maximum interincisal opening.
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.
