Not Applicable

Not yet recruiting

• Conditions: Carious Teeth
• Interventions: Procedure: Prefabricated stainless steel crown group; Procedure: Prefabricated pediatric zirconia crown group

• Registration Number: NCT05910905
• Lead Sponsor: Marmara University

Brief Summary

The study was planned to evaluate and compare the clinical success of prefabricated stainless steel crowns and zirconia crowns used in the primary molars.

The study will be carried out in healthy children aged 6-9 years with caries on more than one surface of the primary molars.

Detailed Description

In this study, zirconia crowns will be compared with prefabricated stainless steel crowns in a randomized controlled manner. The study will be conducted in split-mouth to eliminate the effect of potential confounders. The obtained data will be analyzed using appropriate statistical methods.

Recruitment & Eligibility

• Status: NOT_YET_RECRUITING
• Sex: All
• Target Recruitment: 50

Inclusion Criteria

• Healthy children aged 6-9 years with caries on primary molars
• Children without systemic disease or developmental dental anomalies that may affect caries susceptibility.
• Children whose cooperation is 'positive' or 'absolutely positive' according to the Frankl behavioral scale (Frankl et al., 1962).
• Those with deep dentin caries that do not extend to the pulp in the teeth to be treated
• The molars will be treated with a crown indication.
• Presence of symmetry of the primary molar to be treated in the opposite arch.
• The molar to be treated is in occlusion with the antagonist.
• Presence of caries on at least two surfaces of the molars to be treated.
• Absence of spontaneous pain, abscess, mobility, interradicular lesion in the tooth to be treated
• Patients whose parents and themselves agree to participate in the treatment

Exclusion Criteria

• Children whose treatment cannot be continued on the dental chair due to cooperation
• Molars that will soon be exfoliated, 1/2 of the root has been resorbed
• The presence of bruxism
• The presence of erosion or attrition-related wear on the opposing molar
• The patient does not come to the control appointment or does not want to continue to the research
• Have allergy to local anesthetic, nickel or chromium
• Complications during treatment.

Group	Intervention	Description
Prefabricated stainless steel crown group	Prefabricated stainless steel crown group	Stainless Steel Crown (SSC, Kids Crown, Shinghung, Seoul, Korea)

Primary Outcome Measures

Name	Time	Method
Comparison of clinical success	24 month	According to the criteria reported by Santamaria et al. (2004), clinical success will be categorized as successful, major failure, and minor failure.; Successful: * No clinical signs or symptoms of pulp pathology; * Tooth has exfoliated (without any minor/major failures); * No deformations in the crown/restoration; * No pathology observed in radiographs; Minor failure: * Reversible pulpitis (No need for root canal treatment or extraction); * Crown/restoration loss that can be restored; * Presence of deformations/fractures/perforations in the crown/restoration; * Permanent crown remaining submerged; * Presence of new caries at the margins; Major failure: * Irreversible pulpitis; * Crown/restoration loss that cannot be restored; * Inter-radicular radiolucency; * Internal root resorption

Secondary Outcome Measures

Name	Time	Method
Parental satisfaction	24 month	To assess parental satisfaction regarding the applied restorations, scoring of crowns' appearance, color, shape, size, and general appearance will be requested using a Likert-type scale (Suguna \& Gurunathan, 2021). Score 5 indicates the highest level of satisfaction, while score 1 represents the lowest level of satisfaction.; 1. Not at all satisfied; 2. Not satisfied; 3. Neither satisfied nor dissatisfied (Neutral); 4. Satisfied; 5. Very satisfied
