BACKGROUND The aim of this study was to estimate the prevalence of tooth wear in the aging population of northwest China and to investigate the factors associated with such tooth wear. METHODS Cross-sectional analytic clinical and questionnaire study was performed in 704 participants who had a mean age of 46.5 ± 0.2 SD and of which 367(52.13%) were males and 337(47.87%) female. These particip...
Abstract Background and Objectives: residual cyst is an odontogenic cyst that develops after a tooth with a radicular cyst is extracted so that all or part of the cyst remain in place. These cysts are known as asymptomatic inflammatory odontogenic cysts and form approximately 10% of odontogenic cysts. Case Report: a 30 years old man patient, referred to the department of oral medicine of...
Normal 0 false false false EN-US X-NONE AR-SA Canine retraction to the place of extracted premolar is a basic step in the majority of orthodontic treatments. This is performed frequently by incorrect axis change of canine which moves its root anteriorly. This study is aimed to evaluate canine bodily movements by removable orthodontic appliances and...
Whole-organ regeneration has great potential for the replacement of dysfunctional organs through the reconstruction of a fully functional bioengineered organ using three-dimensional cell manipulation in vitro. Recently, many basic studies of whole-tooth replacement using three-dimensional cell manipulation have been conducted in a mouse model. Further evidence of the practical application to hu...
introduction: the fracture strength of endodontically treated teeth compared to vital ones has long been a source of controversy. it is not clear how root canal therapy affects the stress distribution in teeth. the purpose of this study was to evaluate the changes in stress distribution after root canal therapy in a human maxillary canine by finite element analysis (fem). materials and methods:...
Non-syndromic permanent canine agenesis, or combined with agenesis, or developmental absence of other tooth types, has occasionally been described in the literature, but isolated forms are rarely observed. The purpose of the present retrospective radiographic study was to provide data on the prevalence and distribution of permanent canine agenesis in the Hungarian population. Dental panoramic t...
The purpose of this longitudinal study was to investigate whether acid phosphatase level changes in Gingival Crevicular Fluid (GCF) could be used to monitor bone turnover changes during human orthodontic tooth movement. Seven patients (2 males and 5 females; mean age, 23 years) were selected. Pre-Adjusted Edgewise Appliance (MBT 0.022 X 0.028-inch slot) was strapped up and aligning and leveling...
Introdution: For the proper occlusal interdigitation or coordination of arches in the finishing stage of orthodontic treatment with proper overjet and overbite, there must be a proper mesiodistal tooth size ratio between maxillary and mandibular teeth. The Bolton analysis should be taken into consideration while diagnosing, treatment planning and predicting prognosis in clinical orthodontics. T...
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 ...
The aim of the study was to evaluate factors involved in tooth surface loss due to consumption of dried-roasted seeds. Data of tooth surface loss were collected from a group of 141 patients by clinical examination, interview and by getting the questionnaire regarding dietary factors, oral hygiene practices and pregnancy (for women) filled. No significant differences in tooth surface loss were f...
