In Vitro Evaluation of Flow and Working Time of AH Plus Alone and in Combination with Amoxicillin and Triple Antibiotic Paste

Some researchers have attempted to enhance the antibacterial properties of sealers byaddition of antibiotics while this may affect their physical properties.The purpose of this in vitro study was to comparethe working time and flow of AH Plus sealer alone and in combination with amoxicillin and triple antibiotic paste (TAP). This in vitro study assessed the flow and working time of AH Plus alone (control group) and in combination with amoxicillin and TAP in 1%, 5%, 10% and 25%concentrationsaccording to ANSI/ADA specification NO. 57. The data were analyzed by ANOVA and Tukey’s test. Statistically significant differences were noted in the flow and working time of control group with those of different concentrations of TAP in combination with sealer (p<0.0001).). The working time decreased by an increase inthe concentration of TAP. The AH Plus/ 1% TAP and AH Plus/5% TAP showed higher flow than the control group. The AH plus /1% amoxicillin, AH Plus/5% amoxicillinand AH Plus/10% TAPhad a flow similar to that of the control group. Other groups showed lower flow than the control group. All the alterations in the physical properties of AH Plus sealer in combination with amoxicillin and TAPwere within the ANSI/ADA specification NO 57 standard range.
