The purpose of this research study is to test the effectiveness of two different crowns/caps on teeth for restoration of primary anterior teeth. The two different materials of crowns are esthetic crowns with retentive grooves and without retentive crowns. These crowns are placed on the teeth to restore function, esthetics and prevent further caries and infection.
There are many treatment options available for restoring primary anterior teeth. A clinician's decision to opt for any specific treatment option is based on multiple factors such as the clinician's liking of a specific material or method, esthetic demands by parents, the child's behavior, and moisture and hemorrhage control. Out of many treatment options, preformed zirconia crowns for primary teeth have been available for over a decade. There is insufficient research that compares the success of anterior pediatric zirconia crowns with and without retentive grooves.

Success of prefabricated Zirconia-based primary anterior crowns with retention grooves compared to Zirconia-based primary anterior crowns without retention grooves through clinical outcomes
The clinical outcomes will be measured and reported in the data table based on the number of participants scored on 3-point Likert scale (Ideal, Acceptable, or Not Acceptable) for the following parameters separately: Contour of crown, Gingival health, Staining of crown, Surface roughness of crown, Opposing tooth, Color match of crown, Marginal fit, Marginal discoloration, Recurrent caries.
Time frame: 3, 6, 12, 24 and 36 months
Success of prefabricated Zirconia-based primary anterior crowns with retention grooves compared to Zirconia-based primary anterior crowns without retention grooves through radiographic outcomes
The radiographic outcomes will be measured and reported in the data table based on the number of participants scored on either presence or absence (yes/no) of the findings for the following parameter separately: Widening of periodontal ligament space, periapical pathology, alveolar crestal bone loss, internal root resorption and external root resorption.
Time frame: 3, 6, 12, 24 and 36 months
Parental satisfaction
The questionnaire is a Likert scale of 1-5. 1 equals very dissatisfied. 5 equals very satisfied. The higher the score, the better.
Time frame: 3, 12, 24 and 36 months
Child satisfaction
The questionnaire is a Likert scale of 1-5. 1 equals very dissatisfied. 5 equals very satisfied. The higher the score, the better.
Time frame: 3, 12, 24 and 36 months
Oral health impact during early childhood
Evaluating Oral health impact during early childhood utilizing the Early Childhood Oral Health Impact Scale (ECOHIS) questionnaire. This is rated on a Likert 5-point scale. (0 = never, 1 = hardly ever, 2 = occasionally, 3 = often, 4 = very often)
