Dental Occlusion and Oral Functions

This content covers dental occlusion classifications, the mechanics of mastication, and the coordinated sensorimotor acts of swallowing, speech, and taste.

• Centric occlusion
• Overbite
• Overjet
• Malocclusion
• Angle's classes
• Crowding
• Anterior open bite
• Crossbite
• Mastication
• Bolus formation
• swallowing stages
• Dysphagia
• Phonetics

Functional Anatomy of Gustation and Taste Buds

Gustation is a sensory experience occurring when chemicals in food or drink interact with specialised sensory organs called taste buds.

• gustation
• taste buds
• oropharyngeal system
• fungiform papillae
• foliate papillae
• circumvallate papillae
• neuroepithelial cells
• taste pore
• microvilli
• taste qualities
• sweet
• sour
• bitter

Functional Anatomy of the Oral Cavity

This document explores the functional anatomy of the oral cavity, focusing on the processes of mastication, swallowing, and speech.

• Mastication
• Chewing cycle
• Swallowing
• Speech
• Taste
• Food bolus
• Salivary amylase
• Anterior teeth
• Posterior teeth

Functional Anatomy of Swallowing Stages

Swallowing involves an ordered sequence of events subdivided into the oral stage, pharyngeal stage, and oesophageal stage.

• Oral stage
