Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin and often misdiagnosed as an odontogenic cyst. It is predominantly found in young female patients, located more often in maxilla, and in most cases associated with an unerupted permanent tooth. There are three variants of AOT namely follicular, extra follicular, and peripheral. We report an unusual case of extrafollicular AOT in maxilla of a 50-year old male patient.

Ameloblastic fibroma is a rare mixed odontogenic tumor mostly occurring in the posterior region of the mandible. The peripheral variant is very rare and to the best of our knowledge, only three cases have been reported in the English literature. In this report, we describe a case of peripheral ameloblastic fibroma in a 54-year-old woman with two years of follow-up.

STATEMENT OF THE PROBLEM: Over the past three decades, significant improvements have been achieved in the survival of children with cancer. However, the considerable morbidity which occurs as a result of chemotherapy often restricts the treatment intensity. One of the important dose-limiting and costly adverse effects of cancer therapy is mucositis. Children with hematological malignancies are greatly at risk of developing mucositis. PURPOSE: This study aimed to assess the effectiveness of palifermin in preventing mucositis in children with acute lymphocytic leukemia (ALL) who undergo chemotherapy...

STATEMENT OF THE PROBLEM: In orthognathic surgeries, proper condylar position is one of the most important factors in postoperative stability. Knowing the condylar movement after orthognathic surgery can help preventing postoperative instabilities. PURPOSE: The aim of this study was to evaluate the condylar positional changes after Le Fort I maxillary superior repositioning along with mandibular advancement by using cone beam computed tomography (CBCT). MATERIALS AND METHOD: This cross-sectional study was conducted on 22 subjects who had class II skeletal malocclusion along with vertical maxillary excess...

STATEMENT OF THE PROBLEM: The usage of glass ionomer cements (GICs) restorative materials are very limited due to lack of flexural strength and toughness. PURPOSE: The aim of this study was to investigate the effect of using a leucite glass on a range of mechanical and optical properties of commercially available conventional glass ionomer cement. MATERIALS AND METHOD: Ball milled 45μm leucite glass particles were incorporated into commercial conventional GIC, Ketac-Molar Easymix (KMEm)...

STATEMENT OF THE PROBLEM: Marginal fitness is the most important criteria for evaluation of the clinical acceptability of a cast restoration. Marginal gap which is due to cement solubility and plaque retention is potentially detrimental to both tooth and periodontal tissues. PURPOSE: This in vitro study aimed to evaluate the marginal and internal fit of cobalt- chromium (Co-Cr) copings fabricated by two different CAD/CAM systems: (CAD/ milling and CAD/ Ceramill Sintron)...

STATEMENT OF THE PROBLEM: Prevention is the key factor in acquiring dental and oral health. Community health workers, as a part of health care networks in Iran, play an important role in delivering primary care and their knowledge and attitude directly affect the population whom they interact with in their service scope. PURPOSE: The aim of this research was to evaluate the knowledge and attitude level of community health workers regarding oral health. MATERIALS AND METHOD: This descriptive analytical study was carried out on 1170 community health workers who were employed in health offices in East Azerbaijan to evaluate their knowledge and attitude level about oral health...

In oral cavity neurogenic tumors are rare, especially if they are malignant. Neurofibromas are the benign tumors of nerve sheath origin involving multiple nerve fascicles of the smaller branches of peripheral nerves. They may present as solitary lesions or as a part of generalized syndrome of neurofibromatosis also known as von Recklinghausen's disease (VRD) or very rarely as multiple neurofibromas without VRD. Oral solitary neurofibromas are not uncommon, but histologically plexiform variant is a rare form...

STATEMENT OF THE PROBLEM: Denture stomatitis is the common form of oral candidiasis, which is seen in the form of diffused inflammation in the areas covered by dentures. Many primary studies report the prevalence of denture stomatitis and candida albicans among patients in the Iranian population; therefore, using meta-analysis is valuable for health policy makers. PURPOSE: The purpose of the present study is to determine the prevalence of denture stomatitis and candida albicans in Iran...
