Recruitment & Eligibility

• Status: Ongoing
• Sex: All
• Target Recruitment: 25

Inclusion Criteria

1. Children aged 3 - 6 years with at least two or more carious primary maxillary incisors that require full coverage with Zirconia crowns. Indications for zirconia crowns:
1.1. Multiple surface caries
1.2. Large single surface caries
1.3. Involvement of incisal edge
1.4. Minor caries but high-risk pt
1.5. Following pulp therapy
2. ASA I and ASA II who will receive treatment under general anesthesia
3. Patients available for recalls as outlined in the study protocol

Exclusion Criteria

1. Patient is ASA III or higher
2. Incisors with multiple hypoplastic defects or developmental disturbances
3. Carious primary incisors that are not indicated for zirconia crowns:
3.1. Incisors with root/subgingival caries
3.2. Incisors with very little tooth structure that is inadequate for crown retention , i.e. unrestorable
3.3. Incisors with signs or symptoms of extensive pathology such as mobility grade II or more, internal resorption or excessive external root resorption involving more than one-third of the root, or with significant inter radicular/periapical radiolucency (root and inter radicular/periapical area will be assessed based on a preoperative radiographic examination (with periapical or anterior occlusal radiograph) in cooperative patients)
3.4. Incisors that are expected to exfoliate in 6 - 12 months
4. Patients that show signs of severe bruxism or teeth clenching

Study & Design

Primary Outcome Measures

Name	Time	Method
Crowns retention will be checked by gently probing around the crown at 1 week, 1-, 3-, 6- , 12- and 24-months by the dental surgeon

Secondary Outcome Measures

Name	Time	Method
Gingival health will be measured using the gingival index at 1 week, 1-, 3-, 6- , 12- and 24-months by the dental surgeon
