In the United States, dentists are required to take and pass the National Board Dental Examination (NBDE) in order to obtain a license to practice dentistry. The NBDE is a standardized exam that assesses a dentist's knowledge and skills in various areas of dentistry, including patient assessment, diagnosis, treatment planning, and patient management.
The NBDE is important because it helps to ensure that dentists are competent and qualified to provide safe and effective dental care to their patients. The exam also helps to maintain high standards of dental education and practice in the United States.
