Stainless Steel Crown (SSC, Kids Crown, Shinghung, Seoul, Korea)

3D Crown application: After preparing the molars, the crown was cemented by passive seating with modified glass ionomer cement (GC FujiCEM Evolve, GC America, Alsip, USA).

According to the criteria reported by Santamaria et al. (2004), clinical success will be categorized as successful, major failure, and minor failure.

Successful:

No clinical signs or symptoms of pulp pathology Tooth has exfoliated (without any minor/major failures) No deformations in the crown/restoration No pathology observed in radiographs

Minor failure:

Reversible pulpitis (No need for root canal treatment or extraction) Crown/restoration loss that can be restored Presence of deformations/fractures/perforations in the crown/restoration Permanent crown remaining submerged Presence of new caries at the margins

Major failure:

Irreversible pulpitis Crown/restoration loss that cannot be restored Inter-radicular radiolucency Internal root resorption

Restorations were evaluated to determine success according to modified United States Public Health Service (USPHS) criteria for marginal adaptation, marginal discolouration, secondary caries, anatomical form, retention, postoperative sensitivity and colour matching. Restorations with an "Alpha (A)" score were considered successful, those with a "Bravo (B)" score were considered acceptable, and those with a "Charlie (C)" score were considered unsuccessful. The scoring of the restorations was decided by agreement of both dentists (Ryge G. et al., 1980).

(0) ¼ at the gingival margin, (1) ¼ below the gingival line (apical to the gingival margin) or (2) ¼ above the gingival line (occlusal to the gingival margin) [Muhamed Altinawia et al., 1980].

In this index, the thickness of dental plaque on the mesial, distal, vestibular, lingual tooth surfaces of all teeth or selected teeth and in relation to the gingiva is evaluated by probing. The values determined on the surfaces are summed and the plaque index value of the individual is obtained by taking the mathematical average.

0-No plaque in the area adjacent to the gingiva

1. There is a thin film on the edge of the gingival margin. This formation can only be detected with the help of a probe.
2. There is plaque in the gingival pocket and gingival margin at a level that can be determined by eye. There is no plaque in the aproximal area.
3. A large amount of plaque layer is observed in the gingival pocket and gingival margin. Interdental areas are filled with plaque.
