Pregnant women in the experimental group were given oral and dental health education in groups of maximum five, and the forms were filled out before and one month after the education.

No intervention was made to the pregnant women in the control group, and the forms were completed before and one month after the training.

Before the training was given to the pregnant women in the experimental group who agreed to participate in the study, the Introductory Information Form, the Form for Assessing Pregnant Women's Behaviors Towards Oral and Dental Health, and the Form for Assessing Pregnant Women's Knowledge Levels Towards Oral and Dental Health were applied by face-to-face interview method. The application of the forms took 20-30 minutes. Then, a training time was planned on a suitable date for the pregnant women.

In order to ensure the effectiveness of the training, to answer the questions of the pregnant women effectively and to be able to direct them to the dentist in line with their needs, the training was applied in groups of maximum five people. Lecture, question and answer and demonstration methods were used in the training.

One month after the training, the necessary forms were applied to the pregnant women and the study was terminated.

This form was developed by the researcher by reviewing the literature to determine the knowledge levels of pregnant women about oral and dental health and their educational needs in this direction. The form includes 22 questions assessing the importance of dietary habits for oral and dental health, visiting a dentist during pregnancy, dental and gum treatment during pregnancy, and dental x-rays during pregnancy. The form is evaluated by giving "1 point" for correct answers and "0 point" for incorrect answers in line with the answer key specified in Appendix 4. The lowest score that can be obtained from the form is 0 and the highest score is 22. High scores indicate a high level of knowledge.

This form was developed by the researcher by reviewing the literature to determine the oral and dental health behaviors of pregnant women. The form consists of 16 questions evaluating the behaviors of pregnant women such as current dental health status, frequency of tooth brushing, tooth brushing technique, fluoride toothpaste use, frequency of flossing and frequency of toothbrush replacement.

This form was prepared by the researcher to evaluate the effectiveness and benefits of the training and the opinions of the pregnant women in the experimental group after the training.

This form was developed by the researcher and consisted of two parts: sociodemographic characteristics and obstetric characteristics of pregnant women. Sociodemographic characteristics included questions such as age, education level, employment status, spouse's employment status, income level and family type. Obstetric characteristics included information on the number of pregnancies, number of living children and gestational week. There are 14 questions in the descriptive information form
