The congenital gingival granular cell tumor (CGCT), also as known as congenital epulis, is an unusual benign oral mucosal lesion in newborns. A two-day-old female patient was admitted to the Department of Pediatric Dentistry at Gulhane Medical Academy, Ankara, Turkey with her family, and an intraoral examination showed a CGCT located in the buccal region of the maxillary right first primary molar. In this report, we present a case of CGCT in a newborn.

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: Stem cells from human exfoliated deciduous teeth (SHEDs) are a population of highly proliferative cells, being capable of differentiating into osteogenic, odontogenic, adipocytes, and neural cells. Vitamin D3 metabolites such as 1α, 25-dihydroxyvitamin D3 are key factors in the regulation of bone metabolism. PURPOSE: The aim of this study was to investigate the effect of 1α, 25-dihydroxyvitamin D3 on osteogenic differentiation (alkaline phosphatase activity and alizarin red staining) of stem cells of exfoliated deciduous teeth...

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...
