Was the Tooth Fairy breast fed? The politics of infant tooth decay
… previously established dangers of Baby Bottle Tooth Decay. It was argued by some dentists that this danger increased if the infant was breast fed for an extended period of time. Such claims have gained support from many dentists, and their professional bodies, into the twenty-first century. …

3D tooth surface reconstruction
… a method to reconstruct the surface of a tooth given partial information about its 3D shape (e.g., crown or root information). The shape and deformations of a set of specimens representative of the kind of tooth to reconstruct are learnt offline through statistical analysis, leading to the …

Effects of tooth quality, tooth structure, and cement mixing ratios on dental adhesion
Experiments were performed on a number of bovine dentin specimens with the intent of understanding the effects of dentin quality and preparation on dentinal adhesion. Dentin quality was evaluated by measuring its wetting characteristics and hardness properties. The effects of chemical treatment, …

The Effect of Tooth Presence on Identification of Tooth Socket Lamina Dura Surface: A CBCT Study
… was to evaluate the effect of the presence of tooth structure on the accuracy in identifying the lamina dura surface, facial bone surface, facial and lingual bone margins, socket apex, as well as in facial bone thickness measurement. Materials & Methods: Three fresh cadaver heads were scanned …

Model for tooth development in vitro
… pursued to reproduce fundamental steps of human tooth organogenesis in vitro. The presented model comprises the usage of human dental pulp cells from adult donors that were expanded in monolayer before culture under non-adherent conditions to accomplish a 3D self-organized mesenchymal …

Influence of Tooth Crown Size on Malocclusion
… most instances, one contributing factor may be tooth size. While several researchers have studied whether tooth size contributes to malocclusion, there still is no consensus. Some have found that the mesiodistal widths of the mandibular incisor teeth are significantly larger in subjects with …

Variation Analysis of Involute Spline Tooth Contact
… is to provide an in-depth understanding of tooth engagement in splined couplings based on variations in clearances between mating teeth. It is standard practice to assume that 25-50% of the total spline teeth in a coupling are engaged due to variations from manufacture. Based on the assumed …

THE USE OF TOOTH PIT AND TOOTH/JAW MEASUREMENTS TO IDENTIFY CARNIVORE TAXA RESPONSIBLE FOR DAMAGE ON SCAVENGED BONE
… whether it is possible to distinguish carnivore tooth mark characteristics from other carnivore tooth mark characteristics through two separate analyses: first by examination of tooth pitting and second from carnivore tooth and jaw measurements. This is accomplished by visual analysis and …

Effect of Centric Interference on Canine Tooth Wear
… term effect of a centric interference on canine tooth wear (CTW) and on centric occlusion (CO) and maximal intercuspation (MIP) variance. Materials and Methods: Thirty subjects, 11 males and 19 females, were selected based on inclusion and exclusion criteria. Changes in enamel volume were studied …

Common Pathophysiological Features of Charcot-Marie-Tooth Disease
… neuropathy, also known as Charcot-Marie-Tooth disease (CMT) and related disorders, are a group of genetic disorders causing length-dependant neuropathy, resulting in motor and/or sensory loss progressing from the lower extremities toward the spine. With a population prevalence of 1 in …

Treatment Effects of Incisor Positioning on Anterior Tooth Display
… in maxillary incisor position on anterior tooth display (ATD) in adult (n = 21) and adolescent (n = 38) orthodontic patients. The effects of anterior-posterior, vertical, and angular changes of the maxillary central incisor position during orthodontic treatment were evaluated relative to …

The role of CD133 in mouse incisor tooth epithelium
Since its discovery, CD133 has been used to identify, isolate and characterise many different stem cell types across a wide variety of tissues. Nonetheless, to date not much has been elucidated about its function in these cells. The continuously growing mouse incisor contains a large population of …

Accuracy of Unsegmented CBCT in Mesial-Distal Tooth Measurements
… scans may be used to measure mesial-distal (MD) tooth width for orthodontic diagnosis and treatment planning. Purpose: The objective of this study was to determine if MD tooth measurements from unsegemented CBCT scans in the axial, sagittal, and coronal planes or from a panoramic reconstruction …

In-vitro assessment of modified resin adhesive-tooth interfaces
Objectives:<br/>This research aimed to characterize the interfacial characteristics of modified dental resin-based adhesive systems bonded to sound and carious dental tissue. The modification included the incorporation of matrix metalloproteinase (MMP) inhibitors within the primers of these …

On the Gap-Tooth direct simulation Monte Carlo method
This thesis develops and evaluates Gap-tooth DSMC (GT-DSMC), a direct Monte Carlo simulation procedure for dilute gases combined with the Gap-tooth method of Gear, Li, and Kevrekidis. The latter was proposed as a means of reducing the computational cost of microscopic (e.g. molecular) simulation …
