The desmoplastic variant is a rare form which represents about 4 - 5 % of all ameloblastomas. A few number of studies in the literature have reported “hybrid lesions” which show features of both desmoplastic and conventional ameloblastoma. In this report, we introduce a novel case of hybrid desmoplastic/follicular ameloblastoma of the maxilla, presenting its clinical, radiographic and histopathological features. It has been reported that the desmoplastic variant has a more aggressive behavior than conventional ameloblastoma, owing to its predilection to expand into a large size when affecting the maxilla and the tendency to early invade the surrounding structuresDespite the rarity of desmoplastic ameloblastoma and “hybrid ameloblastoma”, they should be included in the differential diagnosis of slowly growing lesions especially those in the anterior and premolar regions of the jaw. Careful radiographic investigation and accurate histopathological examination of properly taken incisional biopsies will help in providing patients with the best therapeutic option and avoiding waste of time and cost associated with misdiagnosis.

Background: Radical cysts are the most common inflammatory odontogenic cystic lesions that can be treated by Marsupialization, especially if the cyst is large and has vital structures. There are a few things to consider when treating a growing patient with an odontogenic cyst. Marsupialization has more benefits for the growing patient than enucleation to overcome treatment morbidity, such as damage to vital structures, bone loss, jaw growth disorders and pathological fractures.Purpose: This article reports on the success of marsupialization of odontogenic cysts "that have been associated with very decaying deciduous molars" to reduce treatment morbidity and to discuss enucleation in young patients.Materials and Methods: A healthy 9 patients with average age of 8 years old with unilateral radicular mandibular cysts. Marsupialization was done before the end of cyst enucleation incorporating a multipurpose space maintainer.Results: Periodic contraction of the cysts was observed in all patient cystic site . The position of the cyst wall was placed superficially and an enucleation was performed. The treatment result was satisfactory with low morbidity.Conclusion: Marsupialization with a versatile space maintainer for the odontogenic periapical cyst in growing patients has more advantages than enucleation in reducing treatment morbidity.

Purpose: To evaluate the primary and secondary stability when using densah bur in comparison to conventional drilling technique.Methodology: This experimental study was conducted on four dogs using split-mouth fashion so that each side will receive two implants with two different implant-site preparation techniques. In the study group, Densah Bur was used to osseodesify the osteotomy site where conventional cutting drills were used in the control group. The Peak Insertion Torque was used as an evaluation method of primary stability while the Resonance Frequency Analysis was used for both primary and secondary stability.Results: In this study, we collected our measurements via two methods. First, regarding the Peak Insertion Torque, the primary stability was (41 ± 1.2) in the study group, while in the control group, it was (35 ± 1.3) which reveals that the primary stability of the Densah Bur group outweighs the control group with a P-value of (0.003).Second, concerning the Resonance Frequency Analysis, the primary stability of the study group was (85 ± 2.2) while in the control group, the result was (75 ± 1.16) and the P-value of this test (0.0012). On the other hand, the secondary stability was measured by the same device and revealed (85 ± 3.5) of the study group while it shows (71 ± 3.17) in the control group with a P-value of (0.005).Conclusion: From the resulted data, this study verified that the use of osseodensification technique would increase primary stability this could be attributed to the enhancement of bone quality and bone-implant contact by preserving the bulk of bone.

Objective: This study aims to assess the effectiveness of arthrocentesis followed by intraarticular injection of adipose derived stem cells versus hyaluronic acid in treatment of temporomandibular joint osteoarthritis and reversing the ongoing degenerative cascade. Evaluation was based on clinical radiographic and biochemical findings.Materials and Methods: The study included thirty patients suffering from TMJ/OA. Clinical criteria and Computerized Tomography (CT scan) confirmed the diagnosis. Patients were divided into two equal groups; both groups underwent arthrocentesis pursued by hyaluronic acid injection for Group I, and chondrogenic differentiated adipose derived stem cells for Group II. Synovial fluid samples were collected preoperative and at the end of the study (18 months) to assess the TGFβ1 concentration. Clinical data (maximal mouth opening, lateral, protrusive movements, pain and joint sounds) were collected at 3, 6, 12 and 18 months. CT scans were repeated at 18 months.Results: Group I showed initial improvement within clinical parameters but failed to sustain these results till the end of the study, no marked radiographic changes were noted. However, the TGF β1concentration showed significant decrease. Group II showed significant improvement within all parameters, Radiographic findings manifested remodeling of degenerative findings and TGFβ1 concentration was significantly decreased.Conclusion: Adipose derived stem cell is an effective therapeutic treatment for TMJ/OA. It subsided all related clinical dysfunction and abates the ongoing degenerative cycle.
