Odontogenic myxoma of maxilla in an atypical location: a case report

Odontogenic myxoma is a rare and locally invasive benign neoplasm found exclusively in jaws. It presents local invasiveness and tendency to recurrence. According to the World Health Organization [WHO], the odontogenic myxoma is classified as an odontogenic tumor of ectomesenchymal origin. The odontogenic myxoma is a rare entity found in both jaws while the mandible is involved more commonly than the maxilla. We present a kind of odontogenic myxoma in a 24-year old male that was found in an unusual location

[Frequency of the relative presence of hepatitis c virus genome in oral lichen planus]

Oral lichen planus [OLP] is an immunologic mucocutanous disorder. Many factors such as stress, diabetics, HCV, Trauma and hypersensitivity have been introduced as its predisposing factors. Recently, much attention has been paid to the relationship between HCV and OLP. According to different specifications of the virus in different races and geographic conditions, the purpose of this study was the assessment of the presence of HCV in oral lichen planus lesions. We prepared 43 paraffin blocks [29 from OLP and 14 from normal oral mucosa]. The OLP blocks were selected from the archive of Pathology department, dental faculty, Esfahan University of Medical Science. After preparing H and E slides from the paraffin blocks, diagnosis of the lesions was confirmed by a pathologist. Then, all the samples were examined by PCR for HCV genome. The data were analyzed using SPSS software and Fisher's Exact rest with P value of 0.05. Among 43 samples examined, 3 were positive and 26 negative in the OLP group and all the 14 samples belonging to the normal mucosa were negative. According to this study, there was no significant correlation between the presence of Hepatitis C virus genome and OLP lesions [p>0.05]. So, researches on other viruses that are effective in oral diseases with more cases and also doing PCR on the blood and serum of OLP patients are recommended

Evaluation of the efficacy of persica mouth wash on the healing of recurrent aphthous stomatitis [RAS]

Recurrent aphthous stomatitis is one of the most common Diseases of oral mucosa. In spite of its popularity and severity of pain, it dosen't have a routine treatment method. Because of side effects of different chemical drugs, recently, herbal drugs had been used in treatment of these lesions causing a decrease in pain and burning. The purpose of this study was to evaluate the efficacy of persica mouth wash in controlling the pain and decreasing the healing period of Recurrent Aphthous Stomatitis [RAS]. In this double blinded clinical trial study, 24 patients with Recurrent Aphthous Stomatitis without any systemic Diseases were chosen. Each patient was considered as study sample for one time period and then as control for another time period. The patients used persica mouth wash and placebo [as mouth wash] alternatively. A visual Analogue scale [VAS] was used to evaluate the pain and burning of the lesions. For data analysis, chi square, t-test, and spss program was used. There was a significant difference in pain reduction [62.5 and 20.8 percent] and burning reduction [70.8 and 25 percent] between experimental and control groups. There was no significant difference in healing period reduction between the two groups. In this study persica mouth wash as a herbal drug had a positive effect on pain and Burning of the Aphthous lesions. This mouth wash was not effective in reducing the healing period of these lesions. This study suggests the use of persica mouthwash alone or in combination with other drugs to decrease pain and burning of Aphthous lesions
