Certain surgical modalities have been proposed to decrease the invasiveness of the procedure, one is the diode laser therapeutic use. OBJECTIVES: To clinically compare the wound healing rate and the clinical outcome that occurs following the surgical removal of impacted third molar teeth by the conventional gold standard scalpel versus the diode laser incision in diabetic patients. MATERIALS AND METHODS: The study was a split-mouth randomized clinical trial. Twenty-three diabetic patients who needed bilateral surgical removal of impacted mandibular third molar were recruited and randomized. One side (study group) had the incision undergone by the diode laser, while the contralateral side (control group) had the conventional scalpel incision to expose the tooth. Pain was recorded by Visual analogue scale (VAS) after one and seven days, edema was measured by three facial lines after one and seven days, trismus was recorded by measuring the inter-incisal opening after seven days and one month and the wound healing was recorded by the Early wound healing scale (EHS) after seven days and one month postoperative. RESULTS: The clinical outcome showed statistically significant differences in pain, edema, and trismus in the study group, while the control group showed statistically significant differences in wound healing in the early postoperative period, however, a non-significant difference was noted between both groups after one-month follow-up. CONCLUSION: Diode laser incision was an efficient procedure in decreasing the post-operative pain, trismus and edema following removal of impacted third molars.

Multiple techniques, have been used to improve mandibular fracture healing over the years. Low Intensity Pulsed Ultrasound (LIPUS) has recently been used in orthopaedic surgery for improvement of bone union, but was rarely investigated for facial bones. OBJECTIVE: The aim is to compare the efficacy of the use of LIPUS in accelerating bone healing of jaw fractures after open reduction versus the use of conventional miniplates only, investigated both radiographically and clinically. MATERIALS AND METHODS: In an interventional study, 18 cases with jaw fractures were assigned to two groups at random: the study group and the control group, having 9 participants in each group. Both groups underwent open reduction and internal fixation using two conventional miniplates but only the study group received LIPUS stimulation (1.5MHz, 30W/cm2) for 20 minutes on postoperative days 4, 8, 14 and 20. The control group did not receive LIPUS. Clinical evaluation included wound healing, occlusion and pain intensity. Radiographic evaluation using immediate Cone Beam Computerized Tomography (CBCT) and postoperative CBCT after 12 weeks were used to determine the efficacy by measuring various variables, including bone density and radiographic fracture healing. Results After twelve weeks, both groups had normal occlusion and normal sensory function. The wound healing was measured using landry’s score index, there was a significant difference in both groups along the follow up period (p<0.001) and a statistically significant reduction in pain intensity (p<0.001). The average bone density improved statistically significantly in both groups A (p<0.001) and B (p<0.001) when comparing post-operative 12 week values to preoperative values. CONCLUSION: Based on the favourable clinical and acceptable radiographical outcomes of our study, it is concluded that the application of low intensity pulsed ultrasound in mandibular fractures could potentially speed up the healing process, decrease the pain and postoperative complications.","PeriodicalId":7723,"journal":{"name":"Alexandria Dental Journal","volume":"296 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fit is the most significant factor influencing the restoration's durability, retention, and periodontal health. AIM OF STUDY: to compare the marginal fit of CAD/CAM zirconia crowns manufactured using two distinct digital impression techniques. MATERIALS AND METHODS: A typodont tooth in the upper premolar region was prepared to receive a full ceramic crown. A direct scan of the prepared tooth was used to create twenty 3D-printed resin dies. The master dies were divided into two groups at random (n = 10 per group). Group I: scanning the dies digitally. Group II: Digitization of the silicone, scannable impressions. Using cone beam CT, the vertical and horizontal marginal gap were evaluated. RESULTS: Group I had a vertical marginal gap of (119.5 ± 27.0) µm, which was substantially smaller than Group II's (144.8 ± 25.23) µm, and a horizontal marginal gap of (107.5 ± 36.36) µm, which was smaller than Group II's (154.3 ± 49.53) µm.

Correct planning, thorough surgical dissection, and appropriate selection of the kind, size, and shape of the reconstruction material are all necessary for a successful outcome. The appropriate material to use to restore the orbital floor and walls is still up for debate. For that aim, numerous materials have been described from various sources. The ultimate goals involve treating the bony orbital deficiency while restoring anatomy, volume, function, and esthetics. While each type of material has benefits and drawbacks, the ability to fulfill those. AIM OF THE STUDY: This study evaluated the difference in the bone density after orbital floor fracture reconstruction with titanium mesh coated with natural nanohydroxyapatite by electrophoretic deposition versus conventional titanium mesh. PATIENTS & METHODS: This study was carried out clinically on 12 adult patients with fractures of the orbital floor that should be treated with internal fixation and open reduction. The patients were divided into 2 groups, (group A): patients where the reconstruction was done using coated titanium mesh with hydroxyapatite nanocrystals and (group B): the repair and reconstruction of the defect was using conventional titanium mesh. RESULTS: The radiographic differences in bone density between the study and control groups were statistically significant. CONCLUSION: The ongoing study displayed better bone density outcomes in reconstructed orbital floor defects with coated titanium mesh when compared to uncoated titanium mesh.","PeriodicalId":7723,"journal":{"name":"Alexandria Dental Journal","volume":"299 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A recent technique that can achieve ridge expansion is osseodensification. Osseodensification using Densah burs is a technique that condenses bone using specially designed burs rotating in an anticlockwise direction, which will help in increasing the ridge width as well as insertion torque of the implant AIM OF THIS STUDY: Clinical and Radiographic evaluation of ridge expansion in posterior atrophic mandible using osseodensification with simultaneous implant placement. MATERIALS AND METHODS: 12 patients with narrow posterior mandibular ridge with width ≤ 6 mm received implants using osseodensification technique. The amount of ridge expansion, primary and secondary stability at 4 months and marginal bone loss were evaluated at 4 and 8 months. RESULTS: 4 months post-operative bone width was increased by 43.61% and after 8 months bone width was increased by 39.29% in the cervical region and increased by 11.48% at 4 months and 9.89% at 8 months in the middle region and increased by 12.64% at 4 months and 10.57% at 8 months in the apical region. There was also a significant increase in bone density around the implants (p ≤ 0.05) CONCLUSION: Based on the results of this study we concluded that osseodensification is a safe and effective way for expanding narrow posterior alveolar ridges, while increasing bone density around the implant which positively affects the primary and secondary stability; without complications such as dehiscences and fractures of the buccal plate of bone.","PeriodicalId":7723,"journal":{"name":"Alexandria Dental Journal","volume":"234 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
