简要总结
45 teeth fulfilling the inclusion criteria will be included in the study and randomly sorted into Group A, Group B and Group C (control). Detailed medical history, clinical examination and necessary radiographic investigation will be done. Informed consent will be obtained. Pulpectomy will be performed in the primary molars. 3D printed resin endocrowns will be cemented in 15 teeth (Group A ), 3D printed full coverage crowns will be cemented in 15 teeth (Group B) and stainless steel crowns will be cemented in 15 teeth (Group C). Revised FDI criteria will be used to assess the functional, biological and aesthetic properties of the crowns at 1, 3 and 6 months. Periodontal health will be assessed using the plaque index (PI) and Gingival Index (GI) at 1, 3 and 6 months. Intergroup comparison of clinical efficiency will be computed by Chi – square test. Repeated ANOVA test will be done to analyze the data collected at 1, 3 and 6 months. Intergroup comparison of plaque and gingival scores will be computed using independent t test.
