Introduction: Surgical extraction of impacted third molars has become a routine procedure in most of dental clinics. Tissue adhesives based on Nbutyl cyanoacrylate are employed as a non-suture method for intra-oral postsurgical wound closure. Objectives: Evaluation of the clinical post-operative complications after the use of N-butyl cyanoacrylate soft tissue adhesive in closure of mucoperiosteal flaps after the surgical extraction of impacted mandibular third molars compared to the use of conventional silk sutures. Materials and methods: This study was conducted on twenty patients of both sexes ranging from 20 to 30 years of age.Patients were divided equally into two groups (Study and control groups) each with mesioangular impacted mandibular third molar (class II position B according to Pell and Gregory's classification). After the surgical extraction of impacted teeth the flaps were closed using PeriAcryl 90 (Glustitch corporation, Delta, BC, Canada) soft tissue adhesive in the study group and using 3/0 silk sutures in the control group. Patients were evaluated for pain, bleeding, trismus, facial swelling, wound dehiscence and local reaction. Results: There was a statistically significant reduction of pain, bleeding, trismus, wound reaction on using the N-butyl cyanoacrylate (PeriAcryl 90) compared to sutures , concerning wound dehiscence and facial swelling , the results of both materials were nearly the same. Conclusion: The use of the N-butyl cyanoacrylate (PeriAcryl 90) for the closure of mucoperiosteal flaps is a reliable method that can overcome most of complications faced on using conventional silk sutures in addition to ease of manipulation , time saving and safety factors.

INTRODUCTION:Temporomandibular Joint (TMJ) dislocation when condyles travel anterior to articular eminence. It may be reducible or irreducible. Chronic recurrent TMJ dislocation was treated by surgical and nonsurgical methods. Minimally invasive methods include injection of sclerosing agents intra-articular and extra-capsular or botulinum toxin to the surrounding muscles. Prolotherapy is a method of strengthening lax ligaments by injecting various types of sclerosing or proliferant solutions such as ethanolamine oleate 5%, autologus blood and others. It is also known as "ligament sclerotherapy" or "regenerative injection therapy" OBJECTIVES: the study aimed to compare 2 types of prolotherapy (autologous blood & ethanolamine Oleate sclerosing agent) injection in treatment of chronic recurrent temporomandibular joint dislocation. . Thirty patients with chronic recurrent temporomandibular joint dislocation were chosen with certain inclusion and exclusion criteria. Fifteen participants were injected with ethanolamine oleate compared with fifteen patients were injected with autologous blood and were followed-up for six months. The participated patients were assessed at the pre-and post-treatment stages by evaluating pain and mandibular range of motion clinically and radiographically using Magnatic Resonance Imaging (MRI) to evaluate condyle-articular eminence relation in opening and closing mouth. RESULTS: There was no significant difference between both prolotherapies in treating chronic recurrent temporomandibular joint dislocation. CONCLUSIONS: Ethanolamine oleate and autologus blood injection are simple, safe and cost-effective treatment for management of chronic recurrent temporomandibular joint dislocation.

The use of GH powder around dental implants placed immediately in fresh extraction sockets enhanced periimplant bone response.

INTRODUCTION: Removal of wisdom teeth could be challenging owning to limited accessibility, the tooth's structural location and probable nerve damage especially to the inferior alveolar nerve and the lingual nerve. OBJECTIVES: The primary goal of this study is to make a comparison between the lingually based triangular flap and the buccally based triangular flap in terms of post-operative healing and complications. METHODS: 20 patients between the age of 21 and 30 years were randomly selected for mandibular third molar removal from clinic of the Oral and Maxillofacial Department, Faculty of Dentistry, Alexandria University. They were divided into two groups the study group (n=10) was operated using the lingually based triangular flap design and the control group (n=10) was operated using the buccally based triangular flap design. The patients were recalled on the 2 nd , 7 th and 14 th days postoperatively in order to evaluate postoperative pain ,swelling ,wound dehiscence , the incidence of dry socket formation and lingual nerve injury. RESULTS: The lingually based triangular flap showed inferior levels of pain and was statistically significant in the 3rd and 7 th day postoperatively. The lingually based triangular flap design showed less amount of facial swelling and lower incidence of wound dehiscence, dry socket formation and lingual nerve injury but the difference between the groups was all statistically insignificant. CONCLUSION: Lingually based triangular flap design revealed better postoperative healing than buccally based triangular flap design.
