Abstract
Objectives: The author has experimented for sealant retention in order to compare the binding force in the group with bonding agent and without it, by use of bonding agent between at the sealant material and tooth surface. Methods: 80 extracted premolar for Orthodontic treatment were collected and divided as 4 groups as 20 teeth in a group. Sealant with filler component with or without bonding agent and sealant without filler component with or without bonding agent, were processed by each group and the compressive strength was measured with the in order to compare the results of each groups. Results: The compressive strength in filler contained sealant with the bonding agent was revealed as 22.552 MPa and 18.266 MPa in without the bonding agent, and it was significantly difference statistically(p<0.05). The compressive strength in without filler component sealant with the bonding agent was estimated as 22.085 MPa, otherwise 16.131 MPa in without the bonding agent, and it was significantly difference statistically(p<0.05). The compressive strength according to the use of the bonding agent was estimated as 22.319 MPa in bonding agent group and 17.199 MPa in without bonding agent group, and it was significantly difference statistically(p<0.01). The compressive strength according to the filler contained was revealed as 20.409 MPa in filler contained group and 19.109 MPa in no filler contained group and it was no significantly difference statistically(p>0.05). Conclusion: The compressive strength was related with the removal of the sealant from the tooth surface, was not influenced by the filler component, but influenced by the use of the bonding agent, so it was recommended to use the bonding agent before sealant apply at the tooth surface in clinical.
