    Which tooth tissue is the most highly mineralised?

    • Enamel

    • Pulp

    • Dentine

    • Cementum

    Correct Answer
    A. Enamel
    Explanation
    Enamel is the most highly mineralized tooth tissue. It is the outermost layer of the tooth and is composed of hydroxyapatite crystals, which give it its hardness. Enamel is the hardest substance in the human body and provides a protective layer for the underlying dentin and pulp. Its high mineral content makes it resistant to wear and decay.

    All of the following are a vital roles of saliva, except?

    • Whitens teeth

    • Neutralise acid challenges

    • Flush food and bacteria from the oral cavity

    • Acts as a lubricant

    • Delivers calcium, phosphate and fluoride to the tooth surface

    Correct Answer
    A. Whitens teeth
    Explanation
    Saliva plays several important roles in the oral cavity, including neutralizing acid challenges, flushing food and bacteria, acting as a lubricant, and delivering essential minerals to the tooth surface. However, whitening teeth is not one of the vital roles of saliva. Saliva does not have a direct whitening effect on teeth, as tooth color is primarily determined by the underlying dentin and enamel. Whitening treatments usually involve bleaching agents that penetrate the tooth structure to remove stains and lighten the color.

    A saliva test examines both the stimulated and unstimulated saliva, and it is important for a patient to not consume food or dink at least one (1) hour prior to the scheduled saliva check.

    • Both statements are true

    • Both statements are false

    • The first statement is true and the second statement is false

    • The first statement is false and the second statement is true

    Correct Answer
    A. Both statements are true
    Explanation
    The explanation for the given correct answer, "Both statements are true," is that a saliva test does indeed examine both stimulated and unstimulated saliva. Additionally, it is important for a patient to refrain from consuming food or drink for at least one hour prior to the test to ensure accurate results.

    The enamel surface will break down when the pH falls below which number?

    • 4.5

    • 5.0

    • 5.5

    • 4.0

    Correct Answer
    A. 5.5
    Explanation
    The enamel surface of teeth is highly susceptible to acid erosion. When the pH level in the mouth drops below a certain threshold, it can cause the enamel to break down. The correct answer is 5.5, as this is the pH level at which the enamel begins to deteriorate. A pH level below 5.5 indicates an acidic environment that can lead to enamel erosion and tooth decay.

    Tick all of the parameters included in a complete saliva test from the list below:

    • Hydration

    • Viscosity

    • PH

    • Quantity

    • Quality

    • Colour

    Correct Answer(s)
    A. Hydration
    A. Viscosity
    A. pH
    A. Quantity
    A. Quality
    Explanation
    A complete saliva test includes the measurement of hydration, viscosity, pH, quantity, and quality of saliva. These parameters provide valuable information about a person's oral health and overall well-being. Hydration levels indicate the body's hydration status, viscosity measures the thickness of saliva, pH levels indicate acidity or alkalinity, quantity reflects the amount of saliva produced, and quality assesses the composition and presence of any abnormalities. By evaluating these parameters, healthcare professionals can gain insights into various conditions such as dehydration, dry mouth, acidity levels, and potential oral health issues.

    All of the following are prevention strategies for decreased saliva function, except?

    • Increase fluoride exposure

    • Increased caffeine intake

    • Improved cleaning skills

    • Increased masticatory stimuli

    Correct Answer
    A. Increased caffeine intake
    Explanation
    Increased caffeine intake is not a prevention strategy for decreased saliva function because caffeine can actually contribute to dry mouth. Caffeine is a diuretic, which means it increases urine production and can lead to dehydration. Dehydration can cause a decrease in saliva production, leading to dry mouth. Therefore, increasing caffeine intake would not be beneficial in preventing decreased saliva function.

    The most common brand of supplements containing (CPP-ACP) is __?

    • Tooth mousse

    • Tooth creme

    • Tooth paste

    • Mousse paste

    Correct Answer
    A. Tooth mousse
    Explanation
    Tooth mousse is the most common brand of supplements containing CPP-ACP. CPP-ACP stands for casein phosphopeptide-amorphous calcium phosphate, which is a special form of calcium and phosphate that helps to remineralize and strengthen tooth enamel. Tooth mousse is applied topically and helps to prevent tooth decay, protect against acid erosion, and promote the remineralization of teeth. It is commonly used by dental professionals and recommended for individuals with a high risk of dental caries or enamel erosion.

    A typical resting saliva flow rate is around 0.4ml/min or under _____________ seconds.

    • 60

    • 30

    • 10

    • 120

    Correct Answer
    A. 60
    Explanation
    A typical resting saliva flow rate is around 0.4ml/min or under 60 seconds. This means that in less than a minute, a person produces approximately 0.4 milliliters of saliva while at rest.

    Rate this question:

  • 10. 

    Low test results for stimulated saliva may be related to all of the following, except?

    • Level of appetite

    • Salivary gland pathology

    • Head and neck, or total body radiation

    • Diabetes mellitus

    Correct Answer
    A. Level of appetite
    Explanation
    Low test results for stimulated saliva may be related to salivary gland pathology, head and neck or total body radiation, and diabetes mellitus. However, the level of appetite does not directly affect the production of saliva. Saliva production is mainly regulated by the salivary glands and can be influenced by various factors such as medications, dehydration, and certain medical conditions.

    Tick all of following with a pH above 5 from the list below:

    • Water

    • Sugar water

    • Flavoured milk

    • Coca cola

    • Orange juice

    Correct Answer(s)
    A. Water
    A. Sugar water
    A. Flavoured milk
    Explanation
    Water, sugar water, and flavored milk have a pH above 5 because they are all slightly acidic. Coca cola and orange juice, on the other hand, are both acidic with a pH below 5.
