DETERMINATION OF THE EFFECTS OF STAINLESS STEEL CROWNS CEMENTED WITH RESIN CEMENTS ON INTERLEUKIN-10, 12, 18 LEVELS IN GINGIVAL CREVICULAR FLUID

Plain-language summary

This split-mouth clinical study aimed to evaluate the early effects of stainless steel crowns cemented with self-adhesive resin cement and high-viscosity glass ionomer cement on clinical periodontal parameters and interleukin-10 (IL-10), interleukin-12 (IL-12), and interleukin-18 (IL-18) levels in gingival crevicular fluid in pediatric patients. The study included 45 systemically healthy children aged 6-10 years. Stainless steel crowns were placed on the mandibular second primary molars (teeth 75 and 85) in each patient; tooth 75 was cemented with a self-adhesive resin cement (G-Cem ONE™, GC, Japan), while tooth 85 was cemented using a high-viscosity glass ionomer restorative material (EQUIA Forte™ HT, GC, Tokyo, Japan). Plaque index, gingival index, and bleeding on probing were recorded before treatment and one week after cementation. Gingival crevicular fluid samples were collected at the same time points, and IL-10, IL-12, and IL-18 levels were analyzed using the ELISA method. A statistically significant reduction in plaque index values was observed in both cement groups at the one-week follow-up (p\<0.001), whereas no significant differences were found in gingival index or bleeding on probing values (p\>0.05). IL-10 and IL-12 levels did not change significantly in either group, whereas IL-18 levels decreased significantly in the resin cement group and were significantly higher in the glass ionomer cement group postoperatively. These findings suggest that although different cementation materials used for stainless steel crowns yield similar short-term clinical periodontal outcomes, material-related differences may exist in gingival biological responses, particularly with respect to IL-18 levels.
