Finite element modelling and load share analysis for involute worm gears with localised tooth contact [PDF]

, 2001
A new approach has been developed by the authors to estimate the load share of worm gear drives, and to calculate the instantaneous tooth meshing stiffness and loaded transmission errors. In the approach, the finite element (FE) modelling is based on the

Cheek tooth extraction in geriatric versus non‐geriatric horses

Equine Veterinary Journal, EarlyView.
Abstract Background Age‐related dental changes are major contributors to dental disorders in older horses, and cheek tooth extractions are often required to maintain masticatory function and oral comfort. However, limited information is available on clinical and treatment characteristics in this older patient population.

Unravelling the functional biomechanics of dental features and tooth wear [PDF]

, 2013
Most of the morphological features recognized in hominin teeth, particularly the topography of the occlusal surface, are generally interpreted as an evolutionary functional adaptation for mechanical food processing.

Bacteremia in horses undergoing routine dental prophylaxis: Before, during, and after the procedure

Equine Veterinary Journal, EarlyView.
Abstract Background Transient bacteremia after dental procedures is well‐documented in the literature, but the prevalence and clinical significance in horses remains largely unexplored. Objectives To assess whether routine dental prophylaxis in clinically healthy horses is associated with detection of bacteria in blood, using culture and 16S rDNA ...

Grouping of tooth surfaces by susceptibility to caries: a study in 5-16 year-old children [PDF]

, 2004
Background The decline in caries has slowed and this may be indicative of variation in the susceptibility of differing teeth to caries. This study tests the hypothesis that in children, there are groups of tooth sites that exhibit differences in caries ...

Use of a Piezosurgery Technique to Remove a Deeply Impacted Supernumerary Tooth in the Anterior Maxilla

Case Reports in Dentistry, 2015
Deeply impacted supernumerary teeth in the anterior maxillary cannot be generally removed by the conventional labial or palatal surgical approach because of the risk of damaging the surrounding soft tissues and the possibility of injuring the roots of ...

Clinical outcomes of a novel flowable calcium silicate cement in equine endodontic treatment

Equine Veterinary Journal, EarlyView.
Abstract Background Orthograde endodontic treatment of equine cheek teeth is performed infrequently with variable success rates of obturation with calcium hydroxide paste (CHP). A novel flowable calcium silicate cement (eCSC) formulated for use as an obturation material in equine teeth has demonstrated acceptable canal filling volumes and evidence of ...

Amphotericin B nasal spray has no effect on nasal polyps [PDF]

, 2006
Nasal polyps and chronic rhinosinusitis are the products of an inflammatory process. Recently, fungal involvement has been thought to stimulate the development of polyps, and administration of antifungal agents was therefore considered a potential ...

Validation of Virtual Reality Simulations for Anatomical Landmarks in Panoramic Radiographs

Journal of Dental Education, EarlyView.
ABSTRACT Objective This study assessed the validity of panoramic anatomical virtual reality (VR) software among senior dental students. Materials and Methods A total of 79 fourth‐year dental students were randomly divided into two groups in this crossover study. Students’ knowledge of panoramic anatomical landmarks was tested.
