Abstract:
Over the past decade, marked reductions have been recorded in dental caries levels for teenage children in Somerset. These have been documented in BASCD Regional Surveys and reflect a national picture of improving dental health. Nevertheless, over the same period of time, the level of gingival health for Somerset teenagers has remained relatively static.

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:24Facial Feedback Hypothesis
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...

Ingratiation refers to deliberate behaviors aimed at increasing one’s attractiveness or likability to a target person, often for strategic interpersonal or social gain. This set of impression management tactics is especially prevalent in hierarchical contexts, where influencing someone with greater power or authority can yield significant benefits. Several distinct ingratiation strategies have been identified, each leveraging psychological cues to foster favor and affiliation.Opinion...
