Here are the steps you should follow to apply for the Integrated National Board Dental Examination (INBDE):

1. Meet the eligibility requirements. In order to be eligible to take the INBDE, you must have graduated from a dental education program accredited by the Commission on Dental Accreditation (CODA) and be a candidate for licensure as a dentist in the United States.
2. Register with the NBDE. To take the INBDE, you must register with the National Board Dental Examination (NBDE), which administers the exam. You can do this online through the NBDE website.
3. Pay the exam fee. There is a fee to take the INBDE, which must be paid at the time of registration.
4. Schedule an exam date and location. After you have registered and paid the fee, you will need to schedule a date and location for the exam. You can do this online through the NBDE website.
5. Prepare for the exam. It is recommended that you begin preparing for the INBDE well in advance of the exam date. There are a number of study aids and resources available to help you prepare, including textbooks, review courses, and online practice exams.
6. Arrive at the testing center on the day of the exam. Make sure to arrive at the testing center on time, with a valid form of identification and any other materials you are allowed to bring into the exam room (such as a calculator).
7. Take the exam. The INBDE consists of a written exam and a clinical simulation exam. Make sure to pace yourself and manage your time effectively during the exam.
8. Check your scores. You will receive your INBDE scores by mail several weeks after the exam. Your scores are valid for three years from the date of the exam.
