Clinical Success of Stainless Steel Crowns Applied Using Different Cements

Condition(s) studied

Investigational drug(s) / intervention(s)

Use of Calcium silicate based resin cement and resin modified glass ionomer cement: Investigators will restore MIH teeth with stainless steel crowns using calcium silicate-based resin cement and resin-modified glass ionomer cement and evaluate their 1-year success.

Study summary

The main question of the study was to evaluate the one-year clinical success of SSc bonded with two different cement types in MIH teeth with excessive material loss. The researchears will compare the survival rate, effect on gingival health and radiographic success of calcium silicate-based resin-containing cement and resin-modified glass ionomer cement.

Eligibility

Primary outcome measure(s)

• Anatomical Integrity — 3. month, 6. month, 9. month, 12. month
  0: The crown retains its anatomical integrity. 1. The anatomical integrity of the restoration is impaired but functional. 2. The restoration is fractured, displaced or completely lost.
• Marginal Compliance — 3. month, 6. month, 9. month, 12. month
  0: Clinically ideal. No opening is observed between crown and gingiva, no sonde enters. 1. Clinically acceptable. There is an opening between the crown and gingiva that does not extend to the prepared tooth. 2. Clinically unacceptable, tooth mobility and an opening extending to the prepared tooth.
• Proximal Contact — 3. month, 6. month, 9. month, 12. month
  0: Clinically ideal. It is possible to clean the proximal contact area with dental floss. 1. Clinically acceptable. Floss passes hard or loose through the proximal contact area. 2. Clinically unacceptable, proximal contact is not present.

  0 No plaque and discoloration 1. Plaque accumulation of less than 1/3 of the tooth surface or extrinsic staining without plaque accumulation and regardless of the surface covered 2. Plaque accumulation more than 1/3 and less than 2/3 of the tooth surface 3. Plaque accumulation covering more than 2/3 of the tooth surface
