Investigation on Tooth Surface Wear of Cycloid Drives Considering Tooth Profile Modifications [PDF]

Lubricants, 2023
Cycloid drives are widely used in various mechanical systems due to their high reduction ratio, compact size, and high efficiency. Tooth surface wear is a major problem that affects the reliability and durability of cycloid drives.

Clinical adhesiveness of the tooth surface

Acta Odontologica Scandinavica, 1980
The clinical adhesiveness of tooth structure was determined for 43 individuals using intraoral contact angle measurements. There were no statistically significant differences in the critical surface tensions of wetting between groups of males and females nor between the three age groups tested.

Tooth surface loss: an overview

British Dental Journal, 1999
Pathological, non-carious loss of tooth tissue is an increasing problem to the dental profession, with young individuals especially at risk. This paper provides an overview of the problem with an emphasis on the possible causes, particularly those factors which may account for the increased incidence.

pH Response and Tooth Surface Solubility at the Tooth/Bacteria Interface

Caries Research, 2017
Evaluating the physiochemical processes at the tooth surface/bacteria interface is important for elucidating the etiology of dental caries. This study aimed to compare the mineral solubility and protein degradation of coronal enamel (CE) and root dentin (RD), and investigate the involvement of dissolved components in bacteria-induced pH changes using a

Looking into the tooth and its surfaces with ultrasonics

Ultrasonics, 1971
Abstract Three applications of ultrasonics in dental research are described. The first is a matter of simple visualisation of the subsurface structure, the second is a method of studying the intermediate layer between the tooth and a restorative material.

An electrokinetic characterization of human tooth surfaces

Archives of Oral Biology, 1970
Abstract The contact interactions between gingival cells and teeth are thought to be modified by the electrical potentials at their surfaces. The net potentials very close to the surfaces of particles of tooth tissues and synthetic hydroxyapatite have, therefore, been determined by particle electrophoresis.

Some observations of tooth enamel surfaces

Archives of Oral Biology, 1960
Abstract The relatively flat portions of the labial surfaces of human central incisor teeth were polished with various abrasives, in an attempt to produce consistently reproducible surfaces for the comparison of the effects of various treatments.

The Interaction of Salivary Proteins with Tooth Surface

Journal of Dental Research, 1969
Studies of the adsorption of human salivary proteins, in general, and the enzymes amylase, lysozyme, and neuraminidase, in particular, reveal that these proteins differ in their affinities for the surface of enamel. The enzymes studied retained their enzyme activity in the adsorbed state. Only amylase was desorbed by water; lysozyme was desorbed by its

The affinity of chlorhexidine for hydroxyapatite and tooth surfaces

European Journal of Oral Sciences, 1972
abstract – The aim of the present study was to investigate the possibility of increasing the adsorption of chlorhexidine to hydroxyapatite and teeth beyond the level observed for untreated material. For this purpose treatment of samples with 0.01 M glycerophosphate or phytic acid prior to the chlorhexidine adsorption was instituted. The results showed

The Role of Drinks in Tooth Surface Loss

Dental Update, 2004
This paper outlines the current knowledge about the interaction between various groups of drinks and tooth surface loss. It begins by examining how the erosive effects of drinks are assessed in the laboratory and clinically. It then surveys the current erosive effects of various groups of drinks, including carbonated drinks, mineral waters, alcopops ...
