The treatment group were applied pulp capping material using G/CH/TEOS/Ca(OH)2 and the control used Ca(OH)2 . On the 1st and 3rd days, rats were sacrificed. Tissue from 4 rats each group processed for histological preparation. Samples were stained using Hematoxylin-Eosin to examine neutrophils number and immunohistochemistry using anti-COX-2 antibody to identify COX-2 expression. Results: The results showed that neutrophils number and COX-2 expression were decreasing significantly in the treatment group compared to the control group by Kruskal Wallis and ANOVA (pG/CH/TEOS/Ca(OH)2 affects the number of neutrophils and COX-2 expression. The post hoc result showed that the number of neutrophils and COX-2 expression were not significantly lower in the treatment group compared to control group each observation day by Mann-Whitney and Dunnett T-3 test. It is indicating that G/CH/TEOS/Ca(OH)2 and Ca(OH)2 have same effect on neutrophils number and COX-2 expression. The decrease in COX-2 expression and in neutrophils number in dental pulps after pulpotomy with G/CH/TEOS/Ca(OH)2 compared to Ca(OH)2 this findings suggest that the composite material provokes a lower inflammatory processes in the pulp tissue by decreasing C. Conclusion: Gelatin Chitosan TEOS Ca(OH)2 composite have an effect on decreasing the neutrophils number and COX-2 expression in the dental pulp of Wistar rats that experience inflammation."> <xml> Normal 0 false false false EN-ID X-NONE AR-SA </xml><![endif]--><!--[if gte mso 9]><xml> </xml><![endif]--><!--[if gte mso 10]> <style> /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-pagination:none; text-autospace:none; font-size:11.0pt; font-family:"Calibri",sans-serif; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:Arial; mso-bidi-theme-font:minor-bidi; mso-ansi-language:EN-US; mso-fareast-language:EN-US;} </style> <![endif]--> Introduction: Calcium hydroxide (Ca(OH)2) is the material of choice for vital pulp therapies.
