Abstract

Ameloblastic carcinoma is a rare malignant odontogenic tumor that is further classified into being primary orsecondary arising from a preexisting benign ameloblastoma. It affects the mandible in two thirds of the patients.there is no standard treatment protocol for this lesion but radical surgical excision with or without radiotherapyis reported in the majority of cases. In this paper we present a case of a 60 year old female diagnosed with ameloblasticcarcinoma of the mandible that was treated by radical resection of the mandible with selective neckdissection and postoperative radiotherapy.

Abstract

Eleven adult local rabbits (6 female and 5male) were used for this study. The mandible were prepared to study the gross anatomical features. The main gross characteristics feature of the local rabbits mandible the ramus forms a broad, thin and flat plate, the surface of the ramus is greatly increased in its posteroventral portion to form the angle or angular process. The articular surface is elongated and carry on its caudodorsal end a slightly oblique condyloid process, this process in rabbit is raised much above the planes of the molar table and has a prolonged aspect in a longitudinal plan. In front of the shallow mandibular notch, the coronoid process is short and blunt process situated in front of mandibular notch. In the rabbit mandible the alveoli for the canine teeth were absent resulting in a large diastema Mandibular foramen situated on the medial surface immediately behind the last molar. There is a large retroalveolr foramen. The female local rabbit showed significant greater measurement than the male.

استعمل في هذه الدراسة أحد عشر أرنب محلي ح ض ر الفك للدراسة التشريحية العيانية والقياسات الخطية. أظهرت نتائج الدراسة العيانية بتميز عظم الفك في الأرنب وذلك بوجود النتوء الزاوي وكذلك وجود الثقب خلف السنخي. كما أ ن فرعي الفك السفلي يشكلان صفيحة مسطحة رقيقة وعريضة ولوحظ زيادة توسع في سطح الفك باتجاه خلفي بطني ليشكل مايعرف بالنتوء الزاوي للفك. السطح التمفصلي ممطوط ويحمل على نهايته الخلفية الظهرية النتوء اللقمي الذي يكون مائل قليلا وهذا النتوء يرتفع بصورة واضحة فوق مستوى الطواحن وله حافة طويلة في المستوى الطولاني .أمام الثلمة الفكية الضحلة يوجد النتوء التاجي الذي يكون قصير وغير مدبب .لوحظ أ يضا عدم وجود اسناخ الأنياب في الفك السفلي للأرنب مما أدى الى تكوين فلج كبير .اظهرت نتائج القياسات الخطية وجود فروق معنوية بين الذكور والإناث حيث تفوقت الاناث في بعض القياسات على ذكور الأرانب المحلية.

Abstract

Aims of the study: The study aims to evaluate the effect of naproxen and ibuprofen on post maxillo-mandibular fixation (MMF) limited mouth opening. Materials and Methods: The study was per-formed at AL-Jumhoori Teaching Hospital in Mosul City on 30 patients with mandibular fracture and or maxilla who were treated with MMF. The medicaments were allocated to 30 patients using a double blind randomization study who were divided into three groups .Group 1(10 patients) received Ibu-profen. Group 2(10 patients) received Naproxen and Group 3 (10 patients) received placebo . Immedi-ately after MMF release, the maximum mouth opening was measured as the inter-incisal distance be-tween the right upper central incisor and the right lower central incisor. After one hour ,the inter incisal distance was measured again and recorded .The data were analyzed using paired T-test and Duncan multiple analysis. Results: Both Naproxen and Ibuprofen have a statistically significant effect on the improvement of post-MMF limited mouth opening compared to placebo . At the same time there was no significant difference between the effect of Naproxen and that of Ibuprofen on the improvement of post MMF-limited mouth opening .The study also showed that there is inverse correlation between the MMF period and the maximum mouth opening immediately after MMF release. Conclusions: There is no significant difference between the effect of naproxen and that of ibuprofen on the improvement of limited mouth opening after MMF release. The available and cheaper drugs can be prescribed.

Abstract

Background: Maxillofacial injuries pose a therapeutic challenges to trauma, maxillofacial and plastic surgeonspracticing in developing countries. This study was carried out to determine the etiology, injury characteristics andmanagement outcome of maxillofacial injuries at Maysan general hospital in Maysan, southern of Iraq fromNovember 2008 to April 2010.Patients and methods: The data collected included age, gender, etiology, anatomic site of the fracture andtreatment outcome. A total of 134 facial fractures were found in 92 patients,Results: most fractures occurred in adults with age ranging from 21 to 30 years. Men were more affected thanwomen, with a male-female ratio of 4.1:1. Road traffic accidents (RTAs) were the major cause of trauma, followed byinterpersonal violence and gunshots and missiles. When the relation between the gender and the etiology of facialfractures was analyzed, a significant relation was noted between these variables. There was also a relation betweenthe patients’ age and the site of the fractures. The mandible was found to be the most commonly fractured bone inthe facial skeleton, followed by the zygomatic complex. Surgical or non-surgical approach was chosen according tocharacters of each case. There were significant differences between the kind of treatment applied and the site ofthe fracture. Surgical site infection and malocclusion were the most prevalent complications.Conclusion: Road traffic accidents remain the major etiological factor of maxillofacial injuries in our setting. Measureson prevention of road traffic accidents should be strongly emphasized in order to reduce the occurrence of theseinjuries

Abstract

The maxillary and mandibular bones can reflect the status of all of the skeletal bones , any bone lose in the mandible is not due to local factors only such as previous extraction of teeth can be considered as the first sign of osteoporosis in the other skeletal bones and future bone fracture. To obtain statistical data on the alveolar bone height at different regions of the body of the mandible by panoramic radiograph in different age groups of Iraqi males and females. The study include the diagnostic panoramic radiograph of 40 images of randomly selected patients from males and females without sign and symptoms for any systemic diseases affecting the bone. There was a significant high difference between males and females in midline and mental foramen areas.Dentist should pay greater attention to older females patients because they are prone to rapid alveolar bone resorption.

Abstract

All variations of fibro-osseous diseases demonstrate replacement of normal bone by fibrous connective tissue matrix within which varying amounts or combinations of osteoid and mature bone and in some instances cementum-like tissue are deposited. Case Report: Patient aged 46 years, was blind since 1991, admitted to the Department of oral and maxillofacial surgery, (Alsalam Teaching Hospital, Mosul), June 2010, presented with a 14 years duration increasingly bilateral massive hard swelling in the lower jaw. The decision taken according to the clinical and radiographical findings, that matching the presentation of florid cemento-osseous dysplasia, the affected mandible resected through a conservative 3 incisions. Results: the H and E stain examination of the whole resected mass reveals a definite diagnosis of florid cemento-osseous dysplasia. Discussion: Benign gnathic lesions, even massive, could be resected via a conservative surgical approaches, the histopathological findings is a type of investigation and not the only sole clue, while the sum of clinical findings and other aids of investigations make the final decision

Abstract

The pediatric mandible fracture is a rare occurrence when compared with the number of mandible fractures that occur within the adult population.Aims. The purpose of this study was to study the treatment outcomes of fracture mandible in child and adult patients. Patients and methods One hundred forty three patients who sustained mandibular fractures were included in this study one hundred tow (71.33%) were adult patients (sixty five were male and thirty seven patients were female) The general procedure for treating a fractured mandible is first to immobilize the jaw and set the break - "reduction." Often, a surgeon can set the bone simply by manually repositioning it "closed reduction" because it can be done through the skin and does not involve major surgery. Once the bone is set, the jaw must be stabilized and kept stationary for a period of time, to allow the broken segments to grow back together. "fixation," may involve wiring the jaw shut for two to six weeks, Results . one hundred two (71.33%) were adult patients (sixty five were male and thirty seven patients were female) average age of patients was between 16 -75 years and forty one (28.67%) patients were child age between 3- 12 years ( twenty six child were male and fifteen were female). Conclusion. Twenty five patients ( 17.48%) were presented with complication post operatively from total number one hundred forty three, other reported that complications occurred in 19.8% of the patients.

Abstract

Background: The adenomatoid odontogenic tumor is a relatively rare benign epithelial odontogenic tumor. Itcontains both epithelial and mesenchymal components. Few cases presented as an extrafollicular lesion or involvethe mandible or associated with other odontogenic lesions. This paper represents a rare case of an extrafollicularAOT.Case presentation: A 24-year-old female had a painless swelling on the right side of the lower jaw since one-monthduration. Intraorally there was a well defined fluctuant-blue swelling in the right alveolar premolar region measuring1×2 cm obliterating the right lower buccal vestibule. Grade II mobility in the vital 44 and 45 teeth were observed.Panoramic radiographs showed a well-defined pear shaped radiolucent lesion without calcifications between theroots of 44 and 45 that cause roots divergence. The lesion totally enucleated with the tooth 44 which showed rootresorption. Microscopically, a cystic lesion lined by simple odontogenic epithelial cells with areas of polygonalnodular proliferation (sheets, whorled masses with few duct-like structures and clear cells) and amorphouseosinophilic material. This material was PAS –negative, and Congo red positive. The case diagnosed as a cysticextrafollicular variant of AOT with CEOT-like areas.Conclusions This case report describes the first known case of extrafollicular combined AOT/CEOT associated withroot resorption and clear cells. The existence of clear cells suggest a possible aggressive nature and long follow uprecommended

Abstract

Background: The quantity and the quality of available bone, influence the clinical success of dental implants surgery. Cone beam Computed tomography is an established method for acquiring bone images before performing dental implant. Cone beam computed tomography is an essential tool for treatment planning and post-surgical procedure monitoring, by providing highly accurate 3-D images of the patient's anatomy from a single, low-radiation scan which yields high resolution images with favorable accuracy. The aim of study is the Measurement of alveolar bone (height and buccolingual width) and density in the mandible among Iraqi adult subject using CBCT for assessment of dental implant site dimensions.Material and method:The study sample include (60) Iraqi subjects (30 male and 30 females) aged between 20-65 years, sagittal view of Cone beam computed tomography was obtained to measure the height ,width and alveolar bone density of the mandibular anterior area, while coronal view was used to measure the height ,width and alveolar bone density assessment of the mandibular premolar and molar areas. Measurement of mandibular bony height and width was in(mm)and each of the three mandibular areas were represented by seven consecutive measurements for bony height and width and these seven stations were set using an average distance of 2 mm apart while the bone density in Hounsfield unit (HU) with point of measurement represent the mean of density to the area located between the height and buccolingual width.Results:The Statistical analysis of linear measurements of mandibular bone which include the bony height , width and density showed that the mean values of all three measurements are significantly higher in males than females also there was statistically significant difference in the mean bone density of mandibular areas which was highest in anterior area and lowest in the molar area followed by premolar area among both gender, mandibular bony height showed a statistically insignificant very weak negative linear correlation with age in all the three examined mandibular areas while the effect of age on bucolingual width was significantly higher among subjects older than 50 years compared to those younger than 50 years old.Conclusion: The mean bony height was highest in anterior area and lowest in premolar area followed by molar area, while the mean bony width was lowest in anterior area and highest in molar area followed by premolar area , finally the mean bone density was highest in anterior area and lowest in molar area followed by premolar area
