Zinc (Zn) as a nutritional factor affects the health of the oral tissues. This study was done for the evaluation of the effects of zinc deficiency on the oral tissues of rats. The study was carried out on 14 male Wistar rats, cessation of lactation on the 24(th) day after birth. The rats were randomly divided into two groups. Zinc deficient (ZD) diet was(More)
BACKGROUND Radiography plays an important role in the detection of interproximal caries. OBJECTIVES The aim of the present study was to determine diagnostic accuracy of chargecoupled devices (CCD), Photo Stimulable Phosphor (PSP) and film radiography in detecting non-cavitated caries. PATIENTS AND METHODS Seventy-two non-cavitated approximal surfaces of(More)
Oral lichen planus is a chronic inflammatory immune-mediated disease. ICAM-1 and VCAM-1 are vascular adhesion molecules that their receptors are located on endothelial cells and leukocytes. The aim of this study is the immunohistochemical evaluation of VCAM1 and ICAM1 in oral lichen planus and to compare these two markers with normal mucosa for evaluation(More)
Desmoplastic ameloblastoma is an unusual type of ameloblastoma with special histologic and radiographic features and anatomic distribution which differs from those in the classic type of ameloblastoma. The purpose of this article is to assist the dental community in better understanding of this variation of odontogenic tumor. We present a patient with(More)
OBJECTIVE To assess the efficacy of ethanolic extract of propolis in radiation-induced mucositis in rats. METHODS This study was performed in the Dental Faculty, Shahid Rajaee Hospital of Babol University of Medical Sciences, Babol, Mazandaran, Iran from August 2008 to September 2009, It was carried out on 21 male Wistar rats, age 7-11 weeks, and weighing(More)
Various cell proliferation markers are used as diagnostic and prognostic tools in oral lesions. Simultaneous evaluation of these markers can increase the precision of estimation of the proliferative status of different tissues. In this study we investigated the expression of PCNA and Ki-67 as markers of cell proliferation in 15 paraffin embedded samples of(More)
Background and aims. Oral lichen planus is a common chronic inflammatory disease of the oral mucosa with malignant potential, pathogenesis of which is not still well known. Free radicals and reactive oxygen species can play an important role in the pathogenesis of oral lichen planus. The aim of this study was to investigate salivary oxidative stress and(More)
p53 and PCNA expression in keratocystic odontogenic tumors compared with selected odontogenic cysts Summary: The aim of this study was to evaluate p53 and PCNA expression in different odontogenic lesions regarding their different clinical behaviors. Slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (RC), 23 dentigerous cysts (DC),(More)
BACKGROUND Considering molecular target therapy concept in the treatment of oral squamous cell carcinoma (OSCC), many attempts have been performed to introduce an effective molecular marker during recent years. Several investigations have emphasized on the role of CD44 in various cancers and few studies have mentioned CD24 and CD74. The purpose of this(More)
BACKGROUND Many evidences showed that cyclooxygenase-2 (COX-2), an enzyme that catalyzes the synthesis of prostaglandins, has an important role in carcinogenesis. It has been observed in experimental models that selective COX-2 inhibitors suppress the formation of tumors including tongue carcinoma. The aim of this study was to investigate the(More)
