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.

INTRODUCTION: A plenty of materials have been used to increase the success rate, decrease time needed for osseointegration, stimulate bone formation around dental implants. Bisphosphonates increase bone mineral density by inhibiting osteoclast-mediated bone resorption. Alendronate sodium hydrate is a bisphosphonate that potently inhibits bone resorption and is used to treat osteoporosis. A 1% sodium alendronate gel is manufactured and tested in order to accelerate osseointegration around dental implants. OBJECTIVES: This study aims to compare clinically and radiographically the osseointegration for 2 groups of submerged dental implants both in upper anterior and premolar region, first group with the use of local sodium alendronate gel prior to placement of dental implant and the second group without. MATERIALS AND METHODS: A clinical trial on 24 implants divided into 2 groups indicated for dental implant placement in the upper anterior and premolar region selected from the outpatient clinic of the Oral and Maxillofacial department, Faculty of Dentistry, Alexandria University. For the test group 12 implants were placed with sodium alendronate gel just prior to implant placement. For control group 12 implants were placed without sodium alendronate gel. RESULTS: On the 12 week the resonance frequency analysis (RFA) median records were (55.50, 54.0) and the Mean ± SD (55.08 ± 4.94, 54.67 ± 5.69) for the control group and test group, respectively. The bisphosphonate-coated implants showed an increase in implant stability from 0 to 12 weeks more than the control's measures. On the 12 week, the mean peri-implant bone density value was 1417.92 ± 310.54 for control group and 1550.25 ± 286.15 for test group. These increases in the bone density were higher in test group than the control group. CONCLUSIONS: Using sodium alendronate gel with delayed implant placement could enhance the osseointegration around dental implants.

INTRODUCTION:The most common type of trauma is the mandibular fracture with various fixation modalities. One of these modalities is the use lag screw and Herbert cannulated bone screw. OBJECTIVES: Comparison of the clinical and radiographic results of Herbert bone screw (HBS) with conventional Lag screws in anterior mandibular fracture. MATERIALS AND METHODS: Twelve patients were randomly allocated into two groups each including six patients. Group 1 received Herbert bone screw, and group 2 received Lag screw. Follow up visits after 24-hours, one, four, six and twelve weeks for clinical assessment. After twelve weeks, a radiographic examination was conducted to measure the mean bone density along the fracture line. RESULT: After twelve weeks, both groups showed normal occlusion, no intra-fragmentary mobility, no wound dehiscence or infection, normal sensory function and decreased pain intensity level which was statistically significant (p value <0.0001). By comparing post-operative 12 weeks to pre-operative values, the mean bone density showed a statistically significant improvement in values in both groups 1 (p <0.001) and 2 (p<0.0001). CONCLUSION: HBS is comparable to gold standard lag screw with similar outcomes in anterior mandibular trauma. Yet, HBS shows higher compressive feature than LS. Also countersinking is not necessary during HBS insertion unlike LS.

Introduction: Following the extraction of impacted mandibular third molars, there is a risk for developing new, or having persistent osseous periodontal defects on the distal aspects of the adjacent second molars. Objectives: To evaluate the effect of platelet rich fibrin (PRF) on bone healing distal to the second molar following removal of impacted mandibular third molar. Materials and methods: This was a parallel, controlled and randomized clinical trial. Twenty patients aged between 20-30 years, who have mesioangular position B impacted mandibular third molar indicated for surgical removal were selected for this study. Ten patients were taken for the study group, where PRF was applied in the extraction socket of the mandibular third molar and 10 patients for the control group, where the extraction sockets were sutured without receiving PRF. The patients were evaluated clinically for pain, edema and trismus on the second, fourth and seventh day post-operatively and radiographically on the first, second and third month post-operatively. Standardized periapical x-ray films were taken for each patient preoperatively and on the first, second and third postoperative months. Image-J Processing Program was used for the assessment of new bone formation at the distal surface of the second molar. Results: There was less pain and trismus in the study group than in the control group but the difference among them was not statistically significant (p > 0.05). Edema was significantly lower in the study group than in the control group in the second and fourth postoperative days. There was significantly more bone density and higher bone level in the study group than in the control group on the second and third postoperative months (p < 0.05). Conclusion: It is clear that PRF is biocompatible and can improve both soft tissue healing and bone regeneration after surgical removal of impacted mandibular third molar.
