Clinical and Radiographic Evaluation of Different Glass Ionomer Restorative Materials in Primary Molars: A Comparative Randomized Clinical Trial.

Abstract

The study aimed to evaluate and compare the clinical and radiographic success rate of Ketac Universal (3M), GC 9 EXTRA (GC), and Cention N (Ivoclar) restorative materials in primary molars. The study was conducted as randomized clinical trial in children aged 3-8 years old, out of which a total of 75 primary molars were selected in 43 patients who met the inclusion criteria. The sample size was further divided into three groups of restorative materials, which included group I-Ketac Universal (n = 25), group II-GC 9 EXTRA (n = 25), and group III-Cention N (n = 25). Class I restorations were placed randomly according to the computerized randomization in primary molars and evaluated at baseline (1 week), 6 months, and 12 months according to modified United States Public Health Service (USPHS) criteria and bitewing radiographs. On intercomparison of three groups at 12 months, there was no significant difference found, while on pairwise comparison of Ketac Universal and Cention N, there was a significant difference in relation to surface texture (p = 0.04*) and anatomic contour (p = 0.04*) at 12 months. Newly introduced restorative material Cention N exhibited improved physical and mechanical properties and can be recommended as a cost-effective restorative and easy-to-use material in posterior load-bearing primary molars. Restoration of primary teeth continues to be an important aspect of restorative dentistry. The longevity of restorations in primary teeth is significantly different for all materials compared to permanent dentition. This makes the assessment of these restorations as a separate group meaningful. Kataria VG, Patel MC, Bhatt R, et al.
