The teeth of the Polyplacophora Chiton Acanthochiton Rubrolinestus contain biomineralized magnetite crystallites whose biological functions in relation to structure and magnetic properties are not well understood. Here, using superconducting quantum interference device (SQUID) magnetometry, we find that the saturation magnetization (σ(s)) and the Verwey transition temperature (T(v)) of tooth pa...

BACKGROUND Non Syndromic tooth agenesis is a congenital anomaly with significant medical, psychological and social ramifications. There is sufficient evidence to hypothesize that locus for this condition can be identified by candidate genes. The aim of this study was to test whether MSX1 671 T>C gene variant was involved in etiology of Non Syndromic tooth agenesis in Raichur Patients. MATERIA...

UNLABELLED Most people in the world suffer from dental caries, >90% of adults experience caries on enamel and root surfaces during their life. However, the overall roles of all factors in the development of dental caries still remain unclear and are worthy of recent investigation. In this study we used a proteomic 2D-DIGE approach in connection with MS/MS to investigate the different protein ab...

Chorion type may significantly influence the prenatal environment of twins. This study explored the associations between chorion type and gestational age, birth weight, birth length, and the timing of emergence of the first primary tooth in two populations of twins, Australian and Dutch. Additionally, we investigated the relationship between chorion type and birth weight discordance (BWD) in or...

background: urinary tract infections (utis) are one of the most important bacterial infections among children throughout the world. the study aimed to estimate the cost of hospitalization associated with pediatric utis in kermanshah province for the years of 2013 and 2014. methods and materials: this was a cross sectional and descriptive study. the study subjects included all those aged 20 year...

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...

The majority of calcified and connective tissues possess complex hierarchical structure spanning the length scales from nanometers to millimeters. Understanding the biological functionality of these materials requires reliable methods for structural imaging on the nanoscale. Here, we demonstrate an approach for electromechanical imaging of the structure of biological samples on the length scale...

The width and length of the anterior teeth, the dimensions of the frontal dental arches and the dimensions of the hard palate were measured (24 men and 56 women, age range of 18-30 years). The results showed gender-related dimorphism only for the cervical width of the maxillary canine, which were wider in men, p < 0.05. The width-to-length ratios of the maxillary frontal teeth varied from 0.82 ...

Two approaches are currently used to correct overerupted/extruded posterior teeth, the “prosthodontic” and the “orthodontic” one. This report presents a novel orthodontic approach for selective molar intrusion. In two females (26 and 20 years), a modified transpalatal arch (TPA, equivalent to a couple with a 30 g net force) was used to move the tooth bodily. A 50 g force was applied to the over...
