The Design, Build and Validation of a Realistic Artificial Mouth Model for Dental Erosion Research
… necessary for the build and use of an in vitro artificial mouth model built for dental erosion research. It also ascertained the working knowledge of dentists concerning the Human Tissue Act (HTA) and explored an alternative tissue for erosion-testing to human enamel. The design inputs for the …

Survival rate and fracture strength of endodontically treated crowned maxillary incisors with severe defects, restored with different post and core systems after exposure to the artificial mouth.
… rate of the samples after exposure to the artificial oral environment was as follows: 87.5 group 1, 93.75 group 2 and 3, and 100 group 4. The mean fracture strengths and the standard deviations were as follows: 374.34 N (181.47) group 1, 429.36 N (150.16) group 2, 514.70 N (236.54) group …

Survival rate and fracture strength of maxillary incisors, restored with different kinds of full veneers : an in-vitro study
… (EPC), were evaluated after exposure to the artificial mouth. <br>Eighty, caries-free human maxillary central molars were used as abutments for the full veneers. The teeth were randomly divided into one control group and four test-groups of 16 samples each. In control group A, unprepared …

Fracture resistance of molars restored with different types of ceramic partial coverage restorations : an in-vitro study
… teeth were compared, after exposure to the artificial mouth. <br>Ninety-six caries-free human upper first molars were used for the experiment. The teeth were randomly divided into five groups of 16 samples each and a control group (A) with no preparation. In group B, inlay preparation was …

Clarinet toneholes: a study of undercutting and its effects
… Under normal playing conditions, using an artificial mouth to maintain a constant embouchure, it has been demonstrated that undercutting a single hole can shift the frequency ratio between corresponding notes in the lower and upper register closer to 3: 1 (i. e. a musical twelfth). Also, …

A study of the wall vibrations excited during the playing of lip-reed instruments
… wind instrument, consisting of a trombone mouthpiece coupled to a section of brass pipe, is blown using an artificial mouth and the induced wall vibrations measured using a Laser Doppler Vibrometer. The brass pipe’s natural resonance frequencies and bending mode shapes are established and …

A biophysical analysis of the occlusal wear of dental materials
An artificial oral environment was used to clinically simulate the dental wear process and surface friction between opposing maxillary and mandibular elements. Measurement of surface friction between occlusal surfaces of natural premolar teeth demonstrated large variation. High viscosity lubricants …
