Relationship of Dental Caries and Stress: Concentrations in Teeth as Revealed by Photoelastic Tests

Abstract

SYNOPSIS IN INTERLINGUA LE RELATION INTER CARIE DENTAL E AREAS DE CONCENTRATION DE STRESS IN DENTES, STUDIATE PER MEDIO DE TESTS PHOTOELASTIC.-UN technica de ingenieria, revelante concentrationes de stress per configurationes marginal in thermotractate e trenchate modellos sub cargation, esseva applicate a magnificate "dentes" solitari o gruppate ex epoxy-resina simulante le elasticitate de adamante e de dentina. Le experimentos effectuate ha revelate importante concentrationes de stress in punctos de contacto inter dentes adjacente o inter dentes e prostheses e forte stresses distribuite al longo del junction ademanto-dentinal in un piano horizontal inter le punctos de contacto, con multo plus debile stresses in altere sitos. Isto indica un connexion con le reportate phenomeno de initiation de carie dental a punctos de contacto e de su propagation al longo del junction ademanto-dentinal.
