Resin Polymer (NuSmile BioFlx) Compared to Stainless Steel Crowns (3M ESPE) for Restoration of Primary Molar Teeth

Not Applicable

Completed

• Conditions: Dental Caries; Tooth Decay
• Interventions: Other: Resin polymer (NuSmile Bioflx) crown; Other: Stainless steel crown

• Registration Number: NCT06354634
• Lead Sponsor: Virginia Commonwealth University

Brief Summary

The purpose of this research study is to test the effectiveness of two different crowns/caps on teeth for restoration of primary molar teeth. The two different materials of crowns are resin polymer and stainless steel crowns. These crowns are placed on the teeth to restore function and prevent further caries and infection.

Detailed Description

There is a lack of literary evidence for assessment of the properties of Bioflx crowns and their effect on clinical outcomes and parental satisfaction compared to traditionally available options including stainless steel crowns and zirconia crowns. Hence, this study plans to assess the clinical performance and child and parental satisfaction of Bioflx compared to the "gold standard" stainless steel crowns in pediatric patients.

Arm && Interventions

Group	Intervention	Description
All participants	Resin polymer (NuSmile Bioflx) crown	Each participant will receive a BioFLX crown and a stainless steel crown.
All participants	Stainless steel crown	Each participant will receive a BioFLX crown and a stainless steel crown.

Primary Outcome Measures

Name	Time	Method
The success of Bioflx crown in primary molars in comparisons with stainless steel molars through clinical assessments	3, 6, 12, 18, 24 and 36 months	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.
The success of Bioflx crown in primary molars in comparisons with stainless steel molars through radiographic assessments	3, 6, 12, 18, 24 and 36 months	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, furcation radiolucency, periapical pathology, alveolar crestal bone loss, internal root resorption and external root resorption.

Secondary Outcome Measures

Name	Time	Method
Parental satisfaction	3, 12, 24 and 36 months	The questionnaire is a Likert scale of 1-5. 1 equals very dissatisfied. 5 equals very satisfied. The higher the score, the better.
Child satisfaction	3, 12, 24 and 36 months	The questionnaire is a Likert scale of 1-5. 1 equals very dissatisfied. 5 equals very satisfied. The higher the score, the better.
ECOHIS (Early Childhood Oral Health Impact Scale) survey	Pre-operative, 6, 12, 24 and 36 months	The questionnaire is a Likert scale of 1-5. 1 equals never. 5 equals very often. The lower the score, the better.
