The role of erosion, abrasion and attrition in tooth wear

摘要: There is increasing clinical awareness of erosion enamel and dentine by dietary acids the consequent increased susceptibility to physical wear. Enamel characterized acid-mediated surface softening that, if unchecked, will progress irreversible loss tissue, potentially exposing underlying dentine. In comparison, less well understood as composition microstructure are more heterogeneous. Factors which affect erosive potential a solution include pH, titratable acidity, common ion concentrations, frequency method exposure. Abrasion attrition sources wear commonly associated with tooth brushing tooth-to-tooth contact, respectively. A combination abrasion or exacerbates wear; however, further research required understand role fluoride in protecting mineralized tissues from such processes. Abrasive may be seen wide range patients, whereas attritive usually individuals bruxism. Wear processes implicated development hypersensitivity. Saliva confers major protective function against due its pellicle formation, buffering, acid clearance, hard tissue remineralization. This review focuses on physiochemical factors impacting
