An investigation of misalignment effects on the performance of acetal gears [PDF]
, 2017 This paper concentrates on the effects of misalignment on meshing behaviour of acetal gears as hardly any misalignment investigations on polymer gears in the existing literatures. The experimental results show that the wear of acetal gears is insensitive

The Anatomical Record, EarlyView.Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Consequences of Tooth Loss on Oral Function and need for Replacement of Missing Teeth Among Patients Attending Muhimbili Dental Clinic [PDF]
, 2011 Tanzanian oral health services constitute mainly of tooth extractions. Consequently, individuals susceptible to dental caries and periodontal diseases will have a substantial number of missing teeth, which can affect oral function.

The Anatomical Record, EarlyView.Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

The Anatomical Record, EarlyView.Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

The Anatomical Record, EarlyView.Abstract Dental microwear texture analysis (DMTA) has become a well‐established method for dietary inference and reconstruction in both extant and extinct mammals and other tetrapods. As the volume of available data continues to grow, researchers could benefit from combining published data from various studies to perform meta‐analyses.

The Effect of Baking Soda and Vinegar on Tooth Wear
Current Research in Dental SciencesAlternative products used for tooth whitening teeth cause serious wear on tooth surfaces. Knowing the factors that cause tooth wear and their localizations plays an important role in reducing risk factors and treatment.
