Objectives This study was performed to investigate the effects and mechanism of ipriflavone (IP) on the proliferation and osteoblastic differentiation of periodontal ligament cells in vitro and periodontal tissue remodeling following orthodontic tooth movement (OTM) in vivo. Materials and methods Human periodontal ligament cells (hPDLCs) were cultured in vitro and cell counting kit-8, alkalin...

In this study, we examine the health and way of life of some of Taiwan’s earliest Neolithic peoples through studies of skeletons from the Nankuanli East (NKLE) site. The NKLE site is one of three oldest sites (ca. 4500-5000 BP) identified during salvage excavations in 2002-2003 in the Tainan Science Park (TSP) in Shanhua District, Tainan City, in southwestern Taiwan. Approximately 82 extended a...

tooth discoloration induced by endodontic sealers, is a common finding that impairs aesthetic outcome of endodontic treatment. the aim of the present mini literature review, was to summarize the existing data on discoloration potential of different endodontic sealers. the research covered the article published in pubmed and google scholar from 2000 to 2015. the searched keywords included ‘tooth...

abstract : the crown-root fracture is a common tooth injury which compromises the biological width and need proper endodontic and prosthodontic treatment to achieve acceptable clinical outcome. this case report describes clinical management of crown-root fracture in maxillary central incisors which was successfully treated by forceps eruption with 180˚ rotation to restore the biological width. ...

objective: the use of sugar-free chewing gums has been reported to be highly effective in the prevention of dental caries. this study carried out to compare the effect of mastic gum and a xylitol chewing gum on remineralization of caries-like lesions. materials and methods: in this cross-over, single blinded, in situ study, first, artificial caries-like lesions were created in six extracted hum...

Background: Neutron contamination is produced in electron beams of linac when tooth or dental materials are located in the path of beam. Objective: This study aims to determine the neutron dose contamination from different dental restoration materials in electron mode of a linac. Material and Methods: In this experimental study, the neutron dose contamination was calculated in the p...

background: an enchondroma is a benign and a well-differentiated chondrosarcoma is an invasive chondroid tumor with high recurrence potential. in spite of biologic differences, these two tumors have very similar histopathologic appearance. it has been shown that the biologic nature of the connective tissue around benign and malignant tumors varies in the number of mast cells. the aim of this st...

Recently, natural ingredients have focused on the inhibition of bacteria-induced alveolar bone resorption in orthodontic treatment. Jixueteng (Jix), a Chinese traditional medicine, contains several kinds flavonoids given their biological properties. We evaluated effects Jix experimental periodontitis during tooth movement (OTM) rats. To this end, 9-week-old male Wistar rats, which were equipped...
