The aims of this study were to investigate dental crowding from the Copper Age and examine the extent and patterns of wear. Crowding was estimated in 43 adult mandibles using Little's irregularity index. Dental wear, dental diameters, arch width and the presence of third molars were also studied as possible aetiological factors for crowding. The remains were found at the archaeological site of ...

Dental disease and its prevention and treatment comprises approximately 10% of the general equine practitioner’s work. The most common disease affecting the equine hypsodont teeth is the development of dental overgrowths. Brachydont dentition (canines and wolf teeth) are less often diagnosed with dental disease. Gingivitis and periodontal disease as seen in many young horses can affect any toot...

Chapters also examine the wear properties of dental ceramics, glasses and bioactive glass ceramics for tooth repair and replacement;3. Dental composites and antibacterial restorative materials are also considered;4. Provides a concise overview of non-metallic biomaterials for dental clinicians, mat...

OBJECTIVES The purpose of this study was to determine the Young's modulus and the hardness of deciduous and permanent teeth following wear challenges using different dental materials. MATERIALS AND METHODS Wear challenges were performed against four dental materials: A resin-based fissure sealant (Fluoroshield(®)), a glass ionomer based fissure sealant (Vitremer(®)), and two microhybrid compo...

introduction:temporomandibular disorders (tmds) are referred to signs and symptoms involving masti catory muscles, temporomandibular joint and rele vant structures. having been prevalent noticeably, we decided to evaluate the frequency of tmd, among patients referred to the dental clinic of guilan university of medical sciences. materials and methods: in this cross-sectional study, a sample of ...

Worn teeth are a bane to paleobiologists interested in the diets of human ancestors and other fossil primates. Although worn teeth dominate fossil assemblages, their shapes are usually not used to reconstruct the diets of extinct species. The problem is that traditional studies of primate dental functional anatomy have focused on unworn morphology. This has limited most functional analyses to o...

© J Can Dent Assoc 2006; 72(2):155–60 This article has been peer reviewed. Bruxism is nonfunctional clenching or grinding of the teeth. It is a destructive habit that may result in tooth wear. Although research on bruxism is extensive, its etiology remains debatable. The literature suggests that bruxism is correlated with both experienced and anticipated life stress. The purpose of this report ...

OBJECTIVES To evaluate the two-body wear resistance of different artificial denture teeth when opposed to steatite ceramic balls in a dual-axis chewing simulator. METHODS Artificial denture teeth including the ceramic tooth Bonartic CT, the composite resin tooth Condyloform II NFC, the acrylic resin teeth Bonartic TCR, Orthognath, Polystar Selection, SR Orthotyp DCL, and Vitapan Cuspiform, an...
