The aim of this study was to evaluate the clinical success of modified celluloid strip crown restorations applied using interim therapeutic restoration and high-viscosity glass ionomer cement to the maxillary anterior teeth of children with early childhood caries and cooperation problems.
Following the decision on the appropriate size of celluloid strip crown, the tooth will be isolated using roll cottons and the "cavity conditioner" (GC, Japan) will be applied to all surfaces for 10 seconds, washed away and dried with cotton pellets. The selected celluloid strip crown will be filled with a fluoride-releasing bulk fill hybrid glass ionomer cement (EQUIA Forte, GC, Japan) prepared by mixing for 10 seconds in an automatic mixer and placed on the tooth with light pressure. The excess material on the crown margins will be removed with a hand instrument, and the celluloid strip crown will be removed from the tooth. If necessary, the restoration will be polished using a polishing discs. After the crown surface is washed and dried, a nano-filled surface sealant (EQUIA Forte Coat, GC, Tokyo, Japan) will be applied for 10 seconds with a micro-tipped applicator and light cured for 20 seconds. Clinical evaluations will be done at the 3rd, 6th and 12th months.

| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline to 12 months regarding "Anatomic form" | alpha: The general contour of the restorations follows the contour bravo: the general contour of the restoration does not follow the contour of the tooth charlie: The restoration has an overhang does | baseline, 3-month, 6-month,12-month |
| Change from baseline to 12 months regarding "Marginal adaptation" | alpha: Explorer does not catch or has one-way catch when drawn across the restoration/tooth interface bravo: explorer falls into crevice drawn across the restoration/tooth interface charlie: Dentin or base is exposed along the margin bravo: The general contour of the restoration does not follow the contour of the tooth charlie: The restoration has an overhang does | baseline, 3-month, 6-month,12-month |
| Change from baseline to 12 months regarding "Surface roughness" | alpha: the surface of the restoration does not have any surface defects bravo: the surface of the restoration has minimal surface defects charlie: the surface of the restoration has severe surface defects | baseline, 3-month, 6-month,12-month |
| Change from baseline to 12 months regarding "Marginal staining" | alpha: there is no discoloration between the restorations and tooth bravo: there is discoloration on less than half of the circumferential margin charlie: there is discoloration on more than half of the circumferential margin | baseline, 3-month, 6-month,12-month |
