Which of the following actions is considered a misdemeanor of the first degree?

Using the title "dentist" without a license is classified as a misdemeanor of the first degree because it directly infringes upon the legal and regulatory framework that governs the practice of dentistry. In Florida, an individual must have the proper licensure to legally represent themselves as a dentist, as this title signifies a level of certification, professionalism, and adherence to health and safety regulations essential to public trust and safety.

When someone uses the title "dentist" without possessing an appropriate license, it not only misleads the public but also poses potential risks to patient care and safety. Therefore, the law treats this infraction with significant severity, categorizing it as a first-degree misdemeanor to emphasize its seriousness and protect public health.

In contrast, while actions such as practicing with an expired license, storing patient records improperly, or working under supervision without consent may also have their respective consequences and may warrant disciplinary action, they do not carry the same level of offense as using a protected title unlawfully. Each of these actions may incur penalties, but they do not inherently demand the same legal ramifications that come with the unauthorized use of a professional title.
