2: Moderate deposits of plaque adhering to free gingival margin
and adjacent area of the tooth, which can be seen with the naked eyes.
The dental plaque index was scored according to Silness and Loe's classification, as follows: 12 0 = no plaque in the gingival area; 1 = a film of plaque adhering to the free gingival margin
and adjacent area of the tooth; 2 = moderate accumulation of soft deposits within the gingival pocket, on the gingival margin, and/or adjacent to the tooth surface, which could be seen with the naked eye; and 3 = an abundance of soft matter within the gingival pocket and/or on the gingival margin and adjacent tooth surface.
Additionally, the surgical design in this case did not incorporate the free gingival margin
, thus reducing the risk of postsurgical recession or dehiscence formation.
If they scored 1 on the plaque index, which indicates a film of plaque adhering to the free gingival margin
adjacent to the tooth, they were eligible.
The periodontal parameters included the following assessments: (i) pocket depth: the distance of the free gingival margin
to the base of the probable pocket, recorded to the nearest millimeter and (ii) gingival recession, the location of the free gingival margin
in relation to the cementoenamel junction (positive if located apical to the cementoenamel junction and negative if located coronal to the cementoenamel junction).
