Conditions
Brief summary
Fifty healthy cooperative children will be randomly allocated to two groups. Group I (test group) will receive CAD/CAM PEEK crowns, while group II (control group) will receive SSC. The crowns will be evaluated clinically and radiographically.
Detailed description
A two-arm randomized controlled clinical trial. A total of 50 healthy children aged 5-7 years, will be selected from Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry, Alexandria University, Egypt. Children will be selected with scores 3 or 4 Frankl behavioral rating scale. Each child selected will have at least one mandibular second primary molar indicated for full coverage. Written informed consent will be obtained from their guardians. Participants will be randomly allocated into two groups according to the crown that will be used. Group I (test group) will receive CAD/CAM PEEK crowns, while group II (control group) will receive SSC. Using Modified Ryge's Criteria, the crowns will be examined clinically for anatomic form, restoration staining, marginal discoloration, colour match, surface roughness, marginal adaptation, proximal contact, occlusal wear of crown, wear of opposing tooth, and presence of cracks. Gingival and Plaques index scores will be recorded, as well as chairside time, patient and parental satisfaction. The patients will be recalled at 1 week then 3, 6 and 12 months for clinical follow-up. Radiographs will be taken at 6 and 12 months.
