Apart from a good bioactive behavior, composite materials for dental applications should attain high mechanical properties. Thus, the aim of this work was the fabrication and characterization of novel sol-gel derived dental ceramics/bioactive glass composites and the investigation of their mechanical properties such as flexural strength and Weibull modulus. Fourier Transform Infrared Spectrosco...

The purpose of the present study was to evaluate the incidence of dental anomalies in Brazilian patients with Down syndrome. A sample with 49 panoramic x-rays of syndromic patients aged 3 to 33 years (22 male and 27 female) was used. The characteristics of dental anomalies were observed in the panoramic radiographs in both the primary and permanent dentition, according to the ICD (International...

the improvement in survival and local control measures in children with neoplasm in the head and neck region may lead to increased iatrogenic adverse effects of treatment. the aim of this study was to report a new case of the long-term effects of chemoradiotherapy on oral health and dental development in a patient treated for hodgkin's disease at an early age. in this case report, a 26-year-old...

Recently, in spite of advanced and high technology, there is still some problems for positioning head and chin of dental patients treatment for getting photographs of teeths. Furthermore, it is very important to get previous head and shoulder positions of dental patients for comparison present head position and chin of dental patients. In this study, a new designed system method is introduced f...

Incontinentia pigmenti (IP) is a genodermatosis with an X-linked dominant mode of inheritance, characterized by ectodermal, mesodermal, neurological, ocular, and dental manifestations. The purpose of this case study was to report the oral and dental manifestations of an IP case in a Venezuelan pediatric patient. A 9 year-old Venezuelan girl was evaluated. She showed macular pigmented lesions in...

We have used synchrotron x-ray diffraction to study the crystal orientation in human dental enamel as a function of position within intact tooth sections. Keeping tooth sections intact has allowed us to construct 2D and 3D spatial distribution maps of the magnitude and orientation of texture in dental enamel. We have found that the enamel crystallites are most highly aligned at the expected occ...

Haemorrhagic diathesis has been of much concern to health professionals including dentists. It is not infrequent that a dentist becomes the first person to diagnose a bleeding disorder while performing dental treatment. Haemophilia is an X linked disorder with a frequency of about 1:10,000 births. Haemophilia B is much less common than haemophilia A, and affects only 1:300,000 males born alive....

Dental Xray image segmentation (DXIS) is an vitally necessary process in Practical dentistry for diagnosis of periodontitis diseases from an Xray image. DXIS have been investigated to get high accuracy of segmentation. In this paper, we propose a new cooperative scheme that applies semisupervised Fuzzy clustering algorithm to DXIS. Specifically, the Otsu method is used to remove the Background ...
