although the delayed exfoliation of primary teeth among children is a common dental problem, simultaneous presence of primary teeth and corresponding successors is a rare feature in adults. this paper reports an unusual case in which both permanent teeth (molars, premolars, and canines) and primary teeth were present simultaneously. this report describes questions concerning the etiology of ove...

introduction: herpes zoster infection (hzi) is a viral disease with painful skin rashes and blisters in a limited area on one side of the body, often in a strip. osteonecrosis with spontaneous exfoliation of teeth in association with hzi of the mandibular nerve is a rare phenomenon. in this report, such an unusual complication of hzi is presented.   case report: the clinical course of a 53-year...

Background: Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiologic development. A delay in time between the exfoliation of a deciduous tooth and the eruption of its permanent successor may be related to a disorder known as dental retention. This occurs when tooth eruption does not occu...

Submerged tooth is the one that is depressed below the occlusal plane. Dental ankylosis is thought to be a major cause of submergence. Submerged deciduous teeth have the potential to cause malocclusion not only by prevention of their exfoliation and subsequent replacement by permanent teeth but also by causing tilting of proximal teeth and extrusion of opposing tooth. The purpose of this report...

the witkop syndrome is a rare autosomal dominant disorder characterized by the absence of several teeth and abnormalities of the nails. this is the first report of a rare genetic tooth and nail syndrome diagnosed in a 2.5-year-old boy with early exfoliation of the primary canine, absence of the primary incisors, and nail dysplasia. a homozygous mutation was identified in 3’-utr of msx1 gene in ...

PURPOSE The purpose of this retrospective study was to evaluate the radiographic findings with formocresol and ferric sulfate pulpotomies in relation to early tooth loss. METHODS Vital pulpotomies with either ferric sulfate or formocresol, performed by faculty members between 1992 and 2002 at The University of Iowa, were evaluated retrospectively. Radiographic criteria were established to ass...

This article reports the cases of two young children aged 4 and 5 years, in whom biological restorations using tooth fragments were placed in primary molars with severely damaged crowns due to extensive carious lesions. After radiographic and clinical evaluation, tooth fragments obtained from extracted teeth in stock were autoclaved, adjusted to the prepared cavity and bonded to the remaining t...
