Oral Pathology and Medicine

• A swelling that forms when fluid extravasates from the sublingual gland and dissects through the mylohyoid muscle is called a ranula.
• Pain in the buccal gingiva around tooth 47, despite normal response to vitality testing and no evidence of caries, is likely a diagnosis of glossodynia.

Pharmacology and Therapeutics

• Phenobarbital is an example of an enzyme-inducing agent.

• The optimal level of water fluoridation in Canada is 0.7-1.1 ppm.
