26

What is the loss of tooth substances from a chemical process that does not involve bacteria? Usually occurs on the facial surfaces at the gingival third of the crown and often involves the maxillary incisors.

Erosion

Vesicles

32

A localized collection of blood that escaped from blood vessels due to trauma. It is well-defined and with time, changes to a dark color?

Hematoma

33

What part of the body with a temperature of 98.6 degree Fahrenheit is the perfect environment for microorganisms to live?

Mouth

34

Who is responsible for informing a patient when an oral disease is found?

Dental Officer

35

Indicating decalcification process, how do dental caries usually first appear on the enamel?

Chalky white spot

36

What is the process in which the decay stops as it spreads in the enamel? These areas are dark, hollowed out, feel hard to touch, and the explorer may "sink in".

Arrested Carious Lesion

37

What will result when the following events occur: improper cavity preparation (unable to remove all of the decay), inadequate cavity restoration (open margins), and old restorations (restoration break down or are not sealed properly creating a "leaky margin")?

Recurrent Caries
