Including bone plates, lag and Herbert screws. <br /> This study aimed to compare between using Herbert screw versus two conventional miniplates for anterior mandibular fractures fixation concerning timing of surgery, mouth opening, bite force recovery and bone density along the fracture line.<br /> Materials and methods: A randomized controlled clinical trial was carried included twenty patients divided into two equal groups, 10 patients each. The study group received two Herbert screws for fixation of the anterior mandibular fracture, the control group received two conventional miniplates. Clinically operation timing, maximum mouth opening and bite force recovery were assessed. The bone density along the fracture line among both groups was recorded. <br /> Results: The time taken using either techniques was statistically insignificant (P= 0.156). A non-significant difference was found concerning the maximum mouth opening at one week (p= 0.505). In following intervals, a significant difference was detected (p <0.001). An increase in bite force recovery in both groups along all the follow up intervals was noticed; comparing all data between both groups, there was a statistically significant difference towards the study group ( p <0.001). Finally, a statistically significant difference was notable between both groups along the whole follow up period regarding the bone density (p < 0.001).<br /> Conclusion: Herbert screws are found to be highly technique-dependent, requiring advanced surgical skills. Nonetheless, in terms of compression fixation, low cost, fewer devices and hardware required, and improved wound healing outcomes, they surpassed the other treatment modality.https://edj.journals.ekb.eg/article_244282_fcb53bf2f69554f700d9e4d43c5eba6f.pdfThe Egyptian Dental Association (EDA)Egyptian Dental Journal0070-948468320220701A comparative study between the effects of pain receptor blocking agent and lubrication system on pain in case of temporomandibular joint internal derangement2135214724900410.21608/edj.2022.122504.1988ENAhmedRizkMaster Student, Oral and Maxillofacial surgery Department, Faculty of Dentistry, Cairo University, Dentist Ministry

All patients should meet the inclusion criteria of having anterior disc displaced with reduction associated with pain(painful clicking affected temporomandibular joint).Each of the two selected group undergoes arthrocenthesis under local anaesthesia(by delivering auriculotemporal nerve block type anaesthesia in the affected temporomandibular joint). By using the shepard cannula(specially designed cannula for temporomandibular joint arthrocenthesis) using 50cc of lactate ringer's solution(the minimum amount of lavage solution stated by the litreature) and at the end of the surgery each of the 2 groups received intraarticular temporomandibular joint injection with either Curavisc (groupA)or Epicotil(Group B).Then the patient was followed on regular basis on 2,4,and 12weeks intervals by assessing and evaluating the pain intensity using the verbal numerical rating score (V.N.R.S).the study conclusion revealed that Epicotil(pain receptor blocking agent) 20mg/2ml was much more reliable in alleviating pain intensity than Curavisc(lubrication system)https://edj.journals.ekb.eg/article_249004_0ca1fc0435bc008637febd13a4c1372a.pdfThe Egyptian Dental Association (EDA)Egyptian Dental Journal0070-948468320220701Validation of Width-to-Length Ratio in Differentiating between Mandibular Ameloblastomas and Odontogenic keratocysts2149215324900610.21608/edj.2022.133943.2076ENSallyAwadAssociate professor, Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University, Egypt.0000-0002-5250-2315MohamedTawfikProfessor, Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University, Egypt.0000-0001-7897-5535HebaTawfikAssociate professor, Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Hours University, Egypt.0000-0003-1279-8307AmirZaidAssistant professor, Surgical Oncology Department, Faculty of Medicine, and Oncology center, Mansoura University, Egypt.0000-0002-8226-6579AmiraAttiaAssistant professor, Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University, Egypt.0000-0002-9856-1572Journal Article20220419Background: Odontogenic tumors and cysts are benign lesions that can arise in any site<br /> of the jaws, with Ameloblastomas (ABs) and odontogenic keratocysts (OKCs) being the<br /> lesions characterized by local aggressiveness and a high recurrence rate.<br /> <br /> Aim of the study: The current study aimed to validate the efficacy of using the width-to-length ratio as a diagnostic radiographic feature to distinguish mandibular ameloblastomas and odontogenic keratocysts. <br /> <br /> Patients and methods: Twenty cases were selected for each lesion type. The axial views from cone-beam computed tomography (CBCT) were retrospectively reviewed to determine the width-to-length ratio, which was calculated by determining the ratio between the utmost buccolingual width and the utmost perpendicular anteroposterior length of the lesion. Student’s t-test (unpaired) was used to compare the mean ratios of the two lesion types. Statistical significance was set at P < 0.05. <br /> <br /> Results: The mean width-to-length ratios of ameloblastomas and keratocysts were 0.74 and 0.42, respectively. The cutoff point for discriminating the two lesion types was 0.50. The ratios for ameloblastomas were significantly greater than for odontogenic keratocysts (P < 0.001). <br /> Conclusion: The width-to-length ratio is a valid imaging feature that can be used for the differentiation of ABs and OKCs in the body of the mandible.https://edj.journals.ekb.eg/article_249006_3cc35717c4a3141423cb6d383121f9a1.pdfThe Egyptian Dental Association (EDA)Egyptian Dental Journal0070-948468320220701Different modalities used in controlling postoperative sequelae after surgical removal of impacted mandibular third molar: A comparative study2155216324900710.21608/edj.2022.137811.2108ENMohamedEl -AyoutyPostgraduate Master’s Degree student, Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University.0000-0002-2150-2216MohamedAmerProfessor of Oral and Maxillofacial Surgery, Faculty of Dentistry, Mansoura University.0000-0003-2914-3374Ahmed SSalemAssociate Professor of Oral and Maxillofacial Surgery, Faculty of Dentistry, Mansoura University0000-0002-0839-9939Journal Article20220514Objectives: Comparing the effects of submucosal dexamethasone injection, Twin Mix injection, and drain placement on the surgical removal of impacted mandibular third molar regarding postoperative edema, trismus, and pain.<br /> <br /> Material and Methods: 64 patients were selected randomly from Oral and Maxillofacial Surgery Department at Mansoura University. They were divided into four equal groups according to the surgical technique and its modifications. 16 patients were included in each group: The submucosal injection group received dexamethasone injection in the buccal vestibule preoperatively, the Twinmix group received Twin Mix solution injection in the pterygomandibular space preoperatively, the drain group received a tube drain placed submucosally at the buccal vestibule while the control group; had a conventional surgical technique applied. The participants were assessed for pain using visual analog scale (VAS), swelling using facial edema lines, and trismus by a maximum interocclusal opening (MIO) measurement at immediate postoperative period, two days and seven days follow up periods.<br /> <br /> Results: The analysis of pain using VAS showed significant statistical differences in values recorded at all time intervals. Meanwhile,evaluation of edema revealed that there was a significant statistical difference between the groups at values recorded at the second day follow up (P=0.005). Furthermore, no statistically significant difference was showed regarding MIO between all groups at all time intervals<br /> .<br /> Conclusions: Submucosal and Twinmix groups had a better pain control than the drain and control groups. The submucosal group showed the best outcome with regards to swelling. None of the studied groups showed a significant difference concerning trismus.https://edj.journals.ekb.eg/article_249007_c36c0a56d97f015d7299e8593ad4e60a.pdfThe Egyptian Dental Association (EDA)Egyptian Dental Journal0070-948468320220701Evaluation of the Influence of Bone Density on Secondary Implant Stability After Maxillary Sinus Augmentation with and without Bone Grafting: A Randomized Controlled Clinical Trial2165217524900810.21608/edj.2022.141631.2126ENMohamedShokryAssociate Professor of Oral and Maxillofacial Surgery, Faculty of Dentistry, Alexandria University, Egypt0000-0002-7959-8812RaniaFahmyAssociate Professor of Oral Medicine, Periodontology and Oral Radiology, Faculty of Dentistry, Alexandria

Twenty patients requiring the placement of implants in the posterior maxilla with deficient bone height were recruited for the study. Patients were randomly assigned to either group. The formation and density of new bone were evaluated using Cone-Beam Computed Tomography, performed postoperatively and after 6 months. Pearson coefficient was used to correlate bone density and secondary implant stability in both groups. All implants achieved adequate primary stability and were successfully loaded. Both groups showed comparable secondary stability with a mean of (77.9 ± 3.9) for the grafted and (74.8 ± 5.6) for the non-grafted group. Bone density values were (973.6 ±142.5) and (443.7 ± 97.8), and bone height gain was (6.6 ± 0.5) and (6 ± 0.5) for the grafted and the non-grafted groups respectively, with the grafted group showing significantly higher values. Secondary stability showed a significant positive linear correlation with bone density in the grafted group (r = 0.549 at p ≤ 0.05). In conclusion, Sinus floor elevation with and without grafting is considered an acceptable and successful procedure with simultaneous implant placement. Furthermore, higher density values in the grafted sinuses resulted in higher secondary stability.https://edj.journals.ekb.eg/article_249008_8f9ad8e7aeb326340f0de5c53fa5a802.pdfThe Egyptian Dental Association (EDA)Egyptian Dental Journal0070-948468320220701PIEZOSURGERY ASSISTED INFERIOR ALVEOLAR NERVE TRANSPOSITION AND SIMULTANEOUS IMPLANT PLACEMENT FOR MANAGEMENT OF VERTICAL MANDIBULAR RIDGE DISCREPENCIES2177218824626610.21608/edj.2022.142384.2132ENZiadMahmoudLecturer of Oral and Maxillofacial Surgery, Faculty of Dentistry, Alexandria University, Egypt0000-0002-7147-3361LubnaEldidiLecturer of Prosthodontics, Faculty of Dentistry, Alexandria University, Egypt0000-0003-0355-8248Journal Article20220601ABSTRACT <br /> Inferior alveolar nerve (IAN) mobilization for patients suffering from severe vertical bone loss is a viable treatment option However, the technique has been used for over 20 years, it has the potential for postsurgical neurosensory changes. The aim of this study was to evaluate the piezoelectric assisted IAN lateralization and simultaneous implant placement in resorbed mandibular posterior ridges. <br /> Material and methods: Ten patients with posterior mandibular ridge atrophy in need for (IAN) lateralization and immediate implant placement were selected to participate within this study. <br /> Results: The pin tactile discrimination test showed normal sensory function of the inferior alveolar nerve from the 3rd months postoperative (100%) in all patients, Unlike the two-point discrimination test where the inferior alveolar nerve function was (25%) at the 3rd month postoperative then increased to be (50%) at the 6th month postoperative. Implant stability quotient (ISQ) mean values were discovered to be statistically significant increasing immediately postoperative, 3 and 6 months later in all implants. Finally, there was an increase in bone density around the installed implant. <br /> Conclusion: Although the current surgical modality is a technique sensitive, it may be a less risky procedure through the proper preoperative CBCT planning and the use of piezoelectric surgical device.https://edj.journals.ekb.eg/article_246266_9e591ab0bd1b2a65fe3c74b4d1ed7d57.pdf
