Is highly prevalent in adolescents and Can affect any teeth in the permanent dentition

Necrotising ulcerative gingivitis (NUG):

Is a viral infection

Is characterised by vesicles that break down to form yellow-grey ulcers with a red 'halo' of inflammation

Is a painful condition and Is likely to recur in the absence of long-term maintenance

Some sites remain free of disease throughout the life of the patient and Sites of previous disease may remain quiescent indefinitely

Disease activity is present only at sites that bleed

Air is used to deflect the free gingival margin in order to detect:

Supragingival calculus.

Sub gingival calculus.

The cemento enamel junction and inflammation

Smooth root surface.

Dried calculus is easier to detect than wet calculus with the explorer because it is:

Harder.

Softer.

Less slippery, smoother.

Darker

While activating the instrument, the finger rest acts as a:

Pivot point for movement.

Stabilizing point for the hand

Fulcrum for activation of wrist-forearm motion.

Fibroblasts .

Cementoblasts

Osteoblasts

All of the above.

All of the following are true about fibroblasts except:

Fibroblasts are principal connective tissue cells of the periodontal ligament.

Fibroblasts synthesize collagen.

Fibroblasts have pseudopodia like processes

Fibroblasts are not capable of phagocytosis for collagen destruction.

The design feature of the curet that allows it to be used in the deepest area of the sulcus or pocket with the least tissue distention is the:

convex back.

opposite cutting edge.

face.

rounded toe.

A (universal) curet is called that because it:

Is used all over the U.S.

Has one cutting edge.

Is most effective in the removal of calculus.

Adapts to all surfaces of the teeth.

A curet designed to scale and root plane anterior teeth with deep Pockets will have a:

Short,angled shank.

Long, angled shank.

Short, straight shank.

Long,straight shank.

The most reliable means of detecting periodontal pockets:

Visual examination.

Radiographic examination.

Testing for mobility of teeth

Probing.

The mesial furcation of the upper molars is located:
