BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a rare low-grade malignant neoplasm with a predilection for children and young adults, and typically arises in the lung, abdominopelvic region, and retroperitoneum. IMTs in the maxillofacial region are extreme rare. Approximately 50% of IMT harbor rearrangements of the anaplastic lymphoma kinase (ALK) gene at 2p23 with various fusion partne...

Abstract Background Despite growing evidence to support the use of silver diamine fluoride (SDF) for managing carious lesions, and increased interest in SDF worldwide, uptake UK remains limited. This study explored parents’ children’s views acceptability management lesions children. Methods Eleven semi-structured face-to-face interviews were conducted with 11 parent–child dyads recruited from p...

Orthodontic forces disturb the microenvironment of the periodontal ligament (PDL), and induce craniofacial bone remodeling which is necessary for tooth movement. Unfortunately, orthodontic tooth movement is often hampered by ischemic injury and cell death within the PDL (hyalinization) and root resorption. Large inter-individual differences in hyalinization and root resorption have been observe...

OBJECTIVES This study sought to elucidate the effect of autogenous tooth bone material by experimenting on minipig's maxillary sinus and performing histological and histomorphometric analyses. MATERIALS AND METHODS Five 18-24 month-old male minipigs were selected, and right maxillary sinuses were grafted with bone graft material made of their respective autogenous teeth extracted eight weeks ...

herpetosiphon giganteus is a filamentous gliding bacterium. gliding motility is the movement of the cells over surfaces without the aid of flagella. the mechanism responsible for bacterial gliding motility has not been known and there are only a few data on herpetosiphon giganteus. the aim of this study was to observe the ultrastructure and negative staining of isolated strains of herpetosiphon...

background and objective: tuberculosis is still a major health problem, involving about 1/3 of the world´s population. diagnosis is difficult when we only use ziehl-neelson staining. many cases may be missed. a more rapid and sensitive diagnostic method is necessary. pcr may be helpful. the aim of this study was to compare pcr, zieh-neelsen staining and histopathologic findings in diagnosis of ...

Dentin phosphoprotein (phosphophoryn, DPP) is a unique acidic protein in dentin. Except for type I collagen, DPP is the most abundant extracellular matrix protein in dentin. This protein is characterized by high contents of phosphoserine (45-50%) and aspartic acid (35-38%) (Butler et al., 1995)1). Because of the high levels of aspartic acid and phosphoserine, this protein has polyanionic charac...

primary tooth impaction is a rare finding during the development of primary dentition. several factors contribute to the impaction of a deciduous tooth. this report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. this tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the prem...

STATEMENT OF THE PROBLEM By introducing the coloring liquids, it is claimed that it is possible to make the color of frameworks fabricated from zirconium oxide extremely close to the natural tooth color. PURPOSE The purpose of this research was to evaluate the effect of two staining techniques on value changing in zirconia crowns. MATERIALS AND METHOD Three groups A, B, and C, each containi...
