Orofacial trauma is a serious orodental and general health problem that may have medical, esthetic and psychological consequences for children and their parents. When the root of the primary tooth is close to the unerupted permanent tooth, primary tooth trauma may result in developmental disturbances and pulpal reaction in that permanent tooth. We report an unusual case in which injury to the p...

OBJECTIVE To evaluate if there is a relationship between findings of carotid artery calcification (CAC) and periodontal risk in nonsmoker subjects by using panoramic radiographs (DPR). MATERIALS AND METHODS A total of 1146 DPRs were investigated. Gender, age, severity of bone loss, tooth loss, periodontal risk, and findings of carotid calcification were recorded. The periodontal risk was eval...

A 26-year-old man who had end-stage renal disease (ESRD) due to primary glomerulonephritis presented for a routine dental examination. He had peritoneal dialysis (PD) as renal replacement therapy for 2 years. He had smoking one to two packs of cigarettes a day for five years and did not drink alcohol. On clinical examination, the maxillary left canine tooth was absent. The left first molar toot...

Supernumerary teeth are defined as any teeth in excess of normal number. Mesiodens is a supernumerary tooth, in the central region of premaxilla between two central incisors. Dens invaginatus is a developmental anomaly resulting from invagination in the surface of tooth crown before calcification has occurred. Radiographically, it is observed as infolding of a radioopaque ribbon like structure,...

Amelogenesis Imperfecta (AI) is a genetic disease affecting primary and permanent tooth enamel. The incidence varies between 1:700 to 1:4000. The clinical findings include enamel defects, tooth sensitivity, poor dental aesthetics, reduced vertical dimension, dentin dysplasia, and pulpal calcification. Effective treatment planning should incorporate numerous factors such as the patient’s age, di...

Previous reports have suggested delayed dental development in Down's syndrome (mongolism), but without quantification and without exclusion of subjects with cretinism, with a normal chromosomal complement, or with translocations and mosaics of various sorts. Accordingly, the tooth formation of 25 subjects with Down's syndrome, verified as trisomy G by karyotyping and excluding subjects with cre...

The canonical Wnt/β-catenin signaling pathway has been shown to play essential roles in tooth initiation and early tooth development. However, the role of Wnt/β-catenin signaling in cusp patterning and crown calcification in large mammals are largely unknown. In our previous study, miniature pigs were used as the animal model due to the similarity of tooth anatomy and replacement pattern betwee...

The aim of this study was to investigate the relationships between stages calcification various teeth and skeletal maturity among Korean subjects. samples were derived from hand-wrist, panoramic radiographs, lateral cephalograms 743 subjects (359 males 384 females) with ages ranging 6 14 years. Calcification seven permanent mandibular on left side rated according system Demirjian. To evaluate s...

Odontomas are the most common tumor-like (hamartoma) odontogenic lesions in gnathic bones. There two main types: complex odontoma which is composed mainly of amorphous calcification, and compound characterized by irregular tooth-like structures. generally asymptomatic cases involve only one quadrant maxilla or mandible. The treatment choice surgical removal. aim present study to report a rare c...

Calcification of the interclinoid ligament (ICL) of the sella turcica, or sella turcica bridging, has been associated with severe craniofacial deviations. Despite no comprehensive study on the sella turcica bridge, a relationship with tooth and eruption disturbances has been reported. In order to investigate whether congenital absence of the second mandibular premolar, or the presence of a pala...
