Odontogenic myxoma (OM) is a rare and locally invasive benign neoplasm (comprising of 3-6% of all odontogenic tumors) found exclusively in the jaws. OM commonly occurs in the second and third decades, and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling. The radiographic features are variable, and the diagnosis is therefore not easy. This article presents a rare case of OM occurring in the maxilla of a 37-year-old female patient with a brief review of the pathogenesis, clinical, radiological, histopathological, ultrastructural and immunohistochemical characteristics of OM.
Introduction:Superficial facial space infections represent a significant amount of the dental problems that present to hospital. Determining whether an odontogenic swelling is a cellulitis or abscess is difficult, but important as both may require different treatments. The use of an ultrasound may aid in differentiating cellulitis and abscess. This study was done to compare the accuracy of clinical examination alone versus ultrasonography (USG) in the diagnosis of cellulitis and abscess in symptomatic patients with a diagnosis of superficial facial space infection.Materials and Methods:Twenty patients (1870 years) diagnosed as superficial facial space infections by clinical and radiographic examinations were included in the study and patients with significant medical conditions were excluded. The provisional clinical diagnosis was made after a thorough history was taken and clinical examination was performed to determine if the swelling was a cellulitis or abscess. Swelling was then evaluated using the ultrasonic transducer which was placed over the swelling to aid the diagnosis which was again recorded. An incision and drainage procedure was performed after the administration of local anesthesia. The success of the ultrasound intervention versus clinical examination was based on whether frank exudation was detected during incision and drainage of such swellings.Results:The statistical analysis found that USG is a valuable diagnostic aid for detection of abscess or cellulitis in head and neck facial space infections.Interpretation and Conclusion:The findings of this prospective analysis indicate that there was statistical difference between clinical examination alone and USG in making the correct diagnosis. The sensitivity, specificity, positive predictive, negative predictive, and accuracy were not similar for all methods tested. From the results of this study, ultrasound is recommended as an adjunct to clinical examination in differentiating between cellulitis and abscess.
Teratomas are complex lesions composed of diverse tissues from all 3 germinal cell layers and may exhibit variable levels of maturity. Head and neck teratomas are most commonly cervical with the oropharynx (epignathus) being the second commonest location. In this article, clinical presentation, behaviour and associated significance of head and neck teratomas have been highlightened. Because of their obscure origin, bizarre microscopic appearance, unpredictable behaviour and often dramatic clinical presentation, a dental surgeon or a dental specialist should be aware of their clinical presentation and pathology.
Objective: To find out the correlation of gingival biotype with width of keratinized gingiva in maxillary anterior teeth in patients at tertiary care dental hospital presenting for routine periodontal care. Materials And Methods: In this crossectional study, a total of 87 patients were observed in department of Periodontology, Fatima Memorial Hospital College of Medicine and Dentistry Lahore. The gingival biotype (gingival thickness) were determined by using the transparency of the periodontal probe through gingival sulcus. The width of the keratinized gingiva was measured by measuring the distance between the most coronal point of the gingival margin and the mucogingival junction measured at the midpoint of the vestibular face of the teeth using a Michigan O periodontal probe with William’s markings. Results: In this study mean age was 38 years with SD ± 10.88. Forty six percent patients were male and 54% patients were female. Mean width of keratinized gingiva was 4.22mm ± 1.10 while mean gingival biotype was 1.5 mm ± 0.65. The correlation coefficient r=0.277 shows a positive correlation of width of keratinized gingiva with gingival biotype Conclusion: The study concluded that there is a positive correlation of gingival biotype with width of keratinized gingiva in maxillary anterior teeth. Keywords: gingival biotype, width of keratinized gingival, maxillary anterior teeth
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
