Tooth Anatomy01:21

Tooth Anatomy

2.6K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Teeth

2.1K
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...

Local Anesthetics: Common Agents and Their Applications

1.1K
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Oral Cavity01:11

Oral Cavity

3.6K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Local Anesthetics: Chemistry and Structure-Activity Relationship

7.1K
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...

Assessment of the Mouth01:26

Assessment of the Mouth

1.4K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

    Area of Science:

    • Nutrition Science
    • Public Health
    • Dental Health

    Background:

    • Coffee is a globally popular beverage, often associated with both stimulating effects and potential health concerns.
    • Despite its widespread consumption, the health impacts of coffee remain a subject of ongoing scientific investigation.
    • Previous perceptions often linked coffee consumption to adverse health outcomes.

    Purpose of the Study:

    • To review current scientific literature on the systemic and dental health effects of coffee consumption.
    • To evaluate the validity of commonly held negative beliefs about coffee's impact on health.
    • To identify and summarize emerging research on the beneficial roles of coffee.

    Main Methods:

    • Systematic review of recent scientific studies and research papers.
    • Analysis of data pertaining to both general systemic health and specific dental health outcomes.
    • Synthesis of findings to contrast established beliefs with new evidence.

    Main Results:

    • Evidence suggests many purported negative health effects of coffee are not supported by current research.
    • Emerging research indicates coffee consumption may have protective and beneficial effects on overall health.
    • Specific impacts on dental health are also being re-evaluated, moving beyond traditional concerns.

    Conclusions:

    • The scientific understanding of coffee's health effects is evolving, challenging long-held negative assumptions.
    • Coffee consumption is increasingly recognized for potential health benefits rather than solely risks.
