Inclusion criteria
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
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
