Abstract

Background: This study was carried out to evaluate microbial flora of odontogenic infection in Iraqi patients and togain further information on the types of micro-organisms in odontogenic infection, and to determine the value ofCefotaxime as an alternative drug in the treatment of odontogenic infection.Materials and methods: The bacteriology of 20 dento-alveolar abscesses was studied using optimal techniques tocollect, transport and processing specimen. All specimens yielded bacterial growth when cultured for aerobes andanaerobes. Anaerobes were isolated in all patients.Results and Conclusions: Among the aerobic bacteria, streptococci dominated and among the anaerobes theGram negative rode, bactericides ruminicola and fusobacterium nucleatum were most frequently isolated followedby Gram positive cocci. All anaerobic isolate were resist to cefotaxime. The results generally showed that Cefotaximemost effective drug against Gram negative rods and less active against Gram positive cocci and this being relatedto the laboratory results of culture and sensitivity

Abstract

AbstractThe purpose of this study is to determine the prevalence of odontogenic cysts inIraqi populations in Maysan general hospital (Maysan -Iraq) and compare thisprevalence with other international studies.Data of this study were obtained from reports of patients diagnosed withodontogenic cysts between 2007 and 2010. Case records of patients who fit theHistological Classification of the World Health Organization (2005) were included.The following variables were analyzed: gender, age group, anatomical location andhistological type. Odontogenic cysts accounted for 90 % of all lesions biopsiedthroughout the study period. Pain feeling and clinical expansion were recorded inmost of our patients. Mean patient age was (28) years and (61%) of the patients weremales. Radicular cyst was the most prevalent histological type (28.75%), followed byodontogenic keratocyst (25%) then dentigerous cyst (23.75%). The mandible was themost prevalent site of the lesions (55%).Odontogenic cysts appear to have a distinct predilection for the male gender, thethird decade of life and are more frequent in the mandible. Awareness about theprevalence and characteristics of odontogenic cysts is important in primary diagnosisand treatment of these lesions.

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

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

Objective: The purpose of the study was to identify the bacterial composition of the microbiota from odontogenic abscesses and their antimicrobial susceptibilities.Study Design: An aspirate of pus from 37 patients with odontogenic abscesses was obtained by needle aspiration and processed aerobically and under anaerobic conditions. Bacteria were isolated and identified by standard Laboratory methods. Then antimicrobial susceptibility of isolated bacteria was determined by using disc diffusion method.Results: Out of 37 aspirates, 100% yielded positive culture, 34 aspirates contained a mix of microorganisms. A total of 90 strains of bacteria were isolated.Out of 90 strains, 63 strains were anaerobes and 27 strains were aerobes and facultative anaerobes. The mean number of strains per sample was 2.4, two samples were purely anaerobes, 9 samples were mixed anaerobes, 2 samples were purely facultative anaerobes, no purely aerobic, 17 had mixed growth of anaerobes and facultative anaerobes, and 7 samples had mixed growth of aerobes and facultative anaerobic bacteria. Out of 90 isolates, 42 (46.67%) were Gram-positive cocci, 25 (27.78%) were Gram-positive bacilli, 21 (23.33%) were Gram-negative bacilli, and 2 (2.22%) were Candida albicans. The genera of bacteria most frequently isolated were viridans group streptococci, Peptostreptococcus spp., Eubacterium spp., and Prevotella spp. Invitro antibiotic sensitivity of isolated microorganisms were tested for Penicillin, Amoxillin, Ampicillin, Amoxicillin/Clavulanic acid, Erythromycin, and Metronidazole by disc diffusion method. All isolates were sensitive to Amoxillin+ clavulanic acid: 27/27(100%), followed by Ampicillin: 24/27(88.89%), Amoxillin: 23/27(85.19%), Penicillin: 22/27(81.48%), Erythromycin: 12/27(44.44%), and metronidazole: 10/27(37.04%).Conclusions: The present results confirm the existence of mixed infection with predominance of anaerobic and facultative anaerobic bacteria in odontogenic abscesses. Penicillin still possesses antimicrobial activity against the majority of bacteria isolated from odontogenic infections. However, if penicillin therapy has failed to be effective, the combination of penicillin with ampicillin or amoxillin with clavulanic acid is recommended.

Abstract

Background: Odontogenic cysts include a group of osseodestructive lesions that frequently affect the jaws. Thosecysts could derive from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. The aims of thisstudy were to evaluate the immunohistochemical expression of Cyclin D1 in Keratocystic Odontogenic Tumor,Dentigerous cyst and Radicular cyst in epithelium and connective tissue capsule.Materials and Methods: In this study, thirty formalin fixed paraffin embedded tissue blocks of Odontogenic cysts andTumor, consist of 14 Keratocystic Odontogenic Tumor, 8 dentigerous cysts and 8 radicular cysts were analyzedimmunohistochemically for the presence of Cyclin D1 proteins.Results: Strong to moderate expression of Cyclin D1 in epithelium was found in Keratocystic Odontogenic Tumorcases with positive cases percentage was (85.7%). Statistical significant differences (P<0.001) observed whencomparing the three lesions. Immunoreactivity of Cyclin D1 in stroma of Keratocystic Odontogenic Tumor was higherthan in dentigerous cysts and radicular cysts cases. However, the difference was not statistically significant (P<0.067).Conclusion: The results of this study propose that high expression rate of Cyclin D1 might be one of the reasons foraggressive behavior of Keratocystic Odontogenic Tumor and high recurrence rate

Abstract

Background: Odontogenic infection is a common problem facing the dentist and maxillofacialsurgeon in their daily practice.Objectives: To determine the involved fascial spaces, the pathogenic bacteria and their antibioticsensitivity in order to guide clinicians in proper management of odontogenic infections.Materials and methods: Pus samples were obtained from patients with odontogenic infectionsby needle aspiration or sterile swab at the time of abscess drainage. The samples were culturedaerobically and anaerobically conditions, followed by identification of bacteria using differentbiochemical tests and sensitivity test by disk diffusion method.Results: This study included (20) patients, (11) patients were male and (9) female. Thesubmandibular space was the most commonly involved. A mixed facultative anaerobic and strictanaerobic growth was observed in the cultures. Viridans streptococci was the predominant bacteria(42.42%), while the least isolated bacteria was Fusobacterium spp (9.1%). The isolated bacteriawere highly susceptible to azithromycin (87.87%) and least susceptible to amoxicillin (39.39%).Conclusion: Incision and drainage of involved fascial space with the removal of causative toothand the use of appropriate antibiotic remain the ideal treatment option for odontogenic infection.

Abstract

Gorlin-Goltz syndrome, also known as basal cell nevus syndrome, is an uncommon, autosomal dominant inherited disorder, which is characterized by numerous basal cell carcinoma, odontogenic keratocysts and musculoskeletal malformations. However, medical literature documents both common and lesser known manifestations involving the skin, central nervous system, craniofacial anomalies etc. A case of Gorlin –Goltz syndrome with no family history has been reported here, the patient have multiple odontogenic keratocysts, tiny pits involving the palms and soles, rib anomalies, numerous nevi and nodes predominantly present on his face, chest and back. Histopathological study confirms the presence of multiple keratocysts in the jaws and the absence of basal cell carcinoma of the skin. Immunohistochemical study showed negatively p53 staining result. Early diagnosis and treatment is important to prevent long term sequelae including malignancy and oromaxillofacial deformation and destruction.
