RECRUITINGFailure of stainless steel crowns
Level 1 failures was considered when there were any signs of failure related to SSCs. Level 2 failures was considered when there were any signs of related pulpal and periapical pathology. Success was considered when Level 1 and 2 failures were absent.

Periodontal health
* Plaque index 0 = No plaque in the gingival area. 1. = A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may only be recognized by running a probe across the tooth surface. 2. = Moderate accumulation of soft deposits within the gingival pocket, on the gingival margin and/or adjacent tooth surface, which can be seen by the naked eye. 3. = Abundance of soft matter within the gingival pocket and/or on the gingival margin and adjacent tooth surface. * Gingival index 0 = Normal gingiva 1. = Mild inflammation - slight change in color, slight oedema. No bleeding on probing 2. = Moderate inflammation-redness, oedema and glazing. Bleeding on probing 3. = Severe inflammation - marked redness and oedema. Ulceration. Tendency to spontaneous bleeding.
