Final answer:
A Texas dentist must indeed allow State Board of Dental Examiners' representatives access to the facility in the event of a sanitation complaint. This is to ensure compliance with sanitation standards and avoid penalties.
Step-by-step explanation:
The statement that a Texas dentist shall allow immediate access to the entire dental office premises by officers, agents, or employees of the State Board of Dental Examiners if these representatives are acting pursuant to a sanitation complaint is True. In compliance with regulatory standards, dental practices must uphold certain levels of sanitation and are subject to inspection. Failure to comply with these regulations and allow access could result in penalties or other disciplinary actions from the regulatory board.
