A contraction of gingival tissue on the tooth by apically moving towards the gingival margin (marginal retraction) and reconstituting a union of large epithelial adherence between the soft and hard tissues of the dentogingival unit is the effect produced by nonsurgical periodontal therapy on the soft wall of the pocket.
8) Briefly, the slides were selected in a standardized manner, representing the initial, intermediate and final portions of the gingival margin, thus totalizing 10 readings of histological sections at 60-[micro]m intervals for each animal.
Pocket depth--distance in millimeters from the gingival margin to the base of the pocket
Measurements of probing attachment level differ from measurements of probing depth in that the reference point used in probing depth is a changeable one--the crest of the gingival margin.
The maximum incisogingival length was measured from the gingival margin to the incisal edge vertically slightly distal to the middle of the tooth.
Use of glass fiber post was essential to support the crown structure coronal to the gingival margin.
Four aspects must be considered for its assessment: in the first place, the margin of the upper central teeth must be at the same level, the margin of both laterals should be located 1 mm more coronal than that of the central ones, and the gingival margin of the canines must beat the same level than that of the central incisors, thus creating the seagull effect (26) (figure 6).
OH was assessed using the plaque index (PI) of Silness and Loe [1964] on the six Ramfjord teeth (16,12,24,36,32,44-proximal, buccal, lingual) with the use of a disclosing agent (score 0=no dental plaque in the gingiva area, score 1= a film of dental plaque adhering to the free gingival margin (only upon probing), score 2=moderate accumulation of dental plaque at the gingival margin (seen by naked eye), score 3=abundant dental plaque in the gingival margin).
