Your Curriculum Vitae is what you send to employers at the beginning of a job application. It is a simplified version of the resume but serves the same purpose.
For dentistry, a CV should still include the relevant dental licenses you need to practice, any first aid qualifications, and a brief overview of your work experience and education.
It is always good to have a CV to hand in case you need to refer to it in an interview or if you need to pass on information quickly to an employer.
