Ameloblastomas and adenomatoid odontogenic tumors (AOTs) are common epithelial tumors of odontogenic origin. Ameloblastomas are clinico-pathologically classified into solid/multicystic, unicystic, desmoplastic, and peripheral types, and also divided into follicular, plexiform, acanthomatous, granular types, etc., based on their histological features.(More)
BACKGROUND The cranial base is not only an end result of complex segmental growth of rostral end of axial skeleton but also has a tremendous impact on the development of the brain and facial structure. However, little is known about the method for the systematic analysis of the shape of the cranial base in the developing human fetus. We used roentgenograms(More)
Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like(More)
Despite the curious role of tongue in the development of oro-facial structures the tongue remains as rather quiescent organ without bony skeleton. But it is said that neuro-muscular complex of tongue is important in the developmental and functional process. Ankyloglossia and macroglossia are occasionally implicated in the oral diseases. Many authors(More)
BACKGROUND To develop biocompatible bony regeneration materials, allogenic, xenogenic and synthetic bones have been irradiated by an electron beam to change the basic structures of their inorganic materials. The optimal electron beam energy and individual dose have not been established for maximizing the bony regeneration capacity in electron beam(More)
Osteoradionecrosis (ORN) of the jaw is a significant complication of radiotherapy for oral cavity cancer. In addition to antibiotic medication, treatment options such as hyperbaric oxygen therapy, surgical approaches, and combined therapy with pentoxifylline and tocopherol have been recently introduced. In this review article, we will discuss the definition(More)
The cellulose membrane (CM) is a major component of plant cell walls and is both a chemically and mechanically stable synthetic polymer with many applications for use in tissue engineering. However, due to its dissolution difficulty, there are no known physiologically relevant or pharmaceutically clinical applications for this polymer. Thus, research is(More)
BACKGROUND Bizarre parosteal osteochondromatous proliferation (BPOP) is benign and usually occurs in the small tubular bones of the hands and feet, but it is extremely rare in the oral and maxillofacial region. METHODS The present study compares a case of BPOP occurring in the lingual area of the right mandibular body with a representative case of(More)
BACKGROUND Clear cell odontogenic carcinoma (CCOC) is a rare intraosseous carcinoma of the jaw; only 81 cases have been reported in the English literatures. CASE PRESENTATION We reported an additional case and reviewed the existing literature. A 70-year-old woman presented with a large painful radiolucent mandibular lesion from the right canine to the(More)
BACKGROUND Prenatal tongue development may affect oral-craniofacial structures, but this muscular organ has rarely been investigated. METHODS In order to document the physiology of prenatal tongue growth, we histologically examined the facial and cranial base structures of 56 embryos and 106 fetuses. RESULTS In Streeter's stages 13-14 (fertilization age(More)
