The aim of this study is to inform about the development of the software "Oral and Dental Health" that will supplement the course of Science and Technology for K8 students in the primary school curriculum and to carry out an evaluation study of the software. This software has been prepared for educational purposes. In relation to the evaluation of the software, "Educational Software Evaluation Form" was developed by the researchers. Expert evaluation was carried out by 9 computer teachers and 12 teachers of science and technology teaching in primary schools. As a result of the evaluation process, the educational software was found to be satisfactory by the computer teachers and the science and technology teachers. It was also revealed that the computer teachers and science and technology teachers differed in their opinions about the evaluation criteria. Moreover, it was considered necessary to revise and edit the evaluation criteria found in the educational software in line with the opinions of the computer teachers.
