ABSTRACT

Background:

Stainless steel crown are tooth shaped covering which are used universally with preference in primary teeth. With advancements in aesthetic restorative materials the demand of stainless-steel crown is at stake and esthetic alternatives to stainless steel crown for restoring primary molars are gaining more interest. Aim: To evaluate clinically and radiographically the zirconia and stainless-steel crown in primary molars.

Methods:

A randomized controlled study was conducted on children of age group of 5 to 8 years of age visiting, KVG Dental College and Hospital, Sullia and who were meet the inclusion criteria of the study. The study population was randomly divided into two groups of 24 each. Group I: stainless steel crown, Group II: zirconia crown. Post endodontic tooth preparation was done and selected stainless steel and zirconia crowns followed by cemented using type 1 glass ionomer cement. The subjects were be recalled after 3, 6 and 9 months to check gingival index, oral hygiene index and bone health of the tooth using intraoral periapical radiograph.

Results:

There was significant increase in score of gingival indices and OHI score for both SSC and zirconia crowns after 3 months followed by reduction in score at 6 and 9 months. There was no statistically significant difference in alveolar bone height in both groups (zirconia and SSCs) 6 months.

Conclusion:

Zirconia crowns presented to be an excellent choice for primary posterior teeth full coverage restorations. Zirconia crowns performed better than SSCs in the aspect of gingival response and prevention of plaque adhesion.
