Q

gingival recession

A

can lead to sensitivity and root cavities

38
Q

gingival papilla

46
Q

interdental gingiva

A

Extension of the free gingiva that fills the interproximal embrasure between two adjacent teeth

47
Q

gingival groove

A

a shallow groove that runs parallel to the margin of the unattached gingiva and marks the beginning of the attached gingiva

48
Q

attached gingiva

A

extends from the base of the sulcus to the mucogingival junction

oral cavity proper

51
