1. What causes caries? ty ty




a. Food debris ty




b. Materia alba ty




c. Acidic foodstuff ty




d. Bacterialplaque ty




e. Salivaryglycoproteins ty




ANS: D ty




Feedback
A Food debris does not have the structural organization of bacterial
ty ty ty ty ty ty ty ty ty




tplaque biofilm.

B Materia alba does not have the structural organization of bacterial ty ty ty ty ty ty ty ty ty




plaque biofilm.

C Acidic foodstuff lowers pH and may demineralize teeth but does not
ty ty ty ty ty ty ty ty ty ty




tdirectly cause decay.
y ty ty




D Caries is caused by biofilm; also known as bacterial plaque.

D A ceramic inlay on tooth number 14 is an example of an intracoronal
ty ty ty ty ty ty ty ty ty ty ty ty




trestoration, meaning that the restoration is being used to repair

tdamage restricted to the internal parts of a tooth. Materials such as
