      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Encephalotrigeminal angiomatosis, also known as Sturge-Weber Syndrome, is a rare neurological disorder that can cause various symptoms such as mental retardation, hemiparesis (weakness on one side of the body), seizure disorders, and a characteristic facial birthmark called a Port-wine stain. This statement is true as it accurately describes the possible manifestations of Sturge-Weber Syndrome.

    Venous varices are blue and blanch with compression.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Venous varices are enlarged, twisted veins that commonly occur in the legs. The bluish color of varicose veins is due to the deoxygenated blood flowing through them. When pressure is applied to varicose veins, they temporarily blanch or turn white. This is because the pressure temporarily restricts blood flow through the veins. Therefore, the statement that venous varices are blue and blanch with compression is true.

    Peripheral giant cell granulomas are most commonly found between permanent molars and incisors and can cause bone absorption.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Peripheral giant cell granulomas are indeed most commonly found between permanent molars and incisors. These granulomas are benign, reactive lesions that occur in response to local irritation or trauma. They typically appear as reddish-purple, soft, and easily bleeding masses. If left untreated, they can cause bone absorption, leading to further complications. Therefore, the statement "Peripheral giant cell granulomas are most commonly found between permanent molars and incisors and can cause bone absorption" is true.

    Explanation
    Erythroplakia is a condition characterized by red patches in the mouth that cannot be attributed to any other cause. It is commonly associated with tobacco and alcohol use, as well as nutritional deficiencies. These factors can lead to irritation and damage to the oral tissues, causing the development of erythroplakia. Therefore, it is true that erythroplakia can be caused by tobacco, alcohol, and nutritional defects.

  • 10. 

    Erythoplakia usually becomes squamous cell carcinoma.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Erythoplakia is a red patch that appears on the mucous membranes in the mouth. It is considered a potentially malignant condition, meaning it has a high risk of developing into cancer. Squamous cell carcinoma is the most common type of oral cancer, and erythoplakia is known to have a high rate of transformation into this type of cancer. Therefore, it is true that erythoplakia usually becomes squamous cell carcinoma.

    Burning mouth syndrome has detectable clinical lesions.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Burning mouth syndrome is a condition characterized by a burning sensation in the mouth without any visible clinical lesions or abnormalities. The discomfort is often present on the tongue, lips, gums, or throughout the entire mouth. Therefore, the statement that burning mouth syndrome has detectable clinical lesions is false.

    Rate this question:

  • 16. 

    Fungi and bacteria can both cause burning mouth syndrome.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Fungi and bacteria can both cause burning mouth syndrome. This is because both fungi and bacteria can infect the oral cavity and cause inflammation and irritation, leading to symptoms such as a burning sensation in the mouth. Therefore, it is true that both fungi and bacteria can be responsible for causing burning mouth syndrome.

    Females are more commonly affected in smoking-associated melanosis on the anterior labial gingiva.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Females are more commonly affected in smoking-associated melanosis on the anterior labial gingiva. This means that women are more likely to develop melanosis, a condition characterized by dark pigmentation, on the front part of the gums in relation to smoking. This may be due to hormonal differences or other factors that make women more susceptible to the effects of smoking on the gingiva.

    When freckles are see in excess (oral melanotic macules) Puetz-Jegher syndrome and Addison's disease should be considered.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Excessive freckles, also known as oral melanotic macules, can be indicative of Puetz-Jeghers syndrome and Addison's disease. Puetz-Jeghers syndrome is a genetic disorder characterized by the development of polyps in the gastrointestinal tract, along with freckles on the lips, oral mucosa, and other areas. Addison's disease, on the other hand, is a hormonal disorder that affects the adrenal glands and can cause increased pigmentation of the skin, including freckles. Therefore, it is true that when freckles are seen in excess, these two conditions should be considered.

    The palate is the most common place for oral nevi.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the palate, which is the roof of the mouth, is indeed the most common location for oral nevi. Oral nevi are pigmented lesions or moles that can occur in the mouth. While they can appear in other areas of the mouth as well, such as the gums or tongue, the palate is the most frequently affected site. This is due to the higher concentration of melanocytes, the cells responsible for producing pigment, in the palate compared to other oral tissues. Therefore, it is accurate to say that the palate is the most common place for oral nevi.

    Neurofibromatosis (von Recklinghousen's disease) is autosomal dominant.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Neurofibromatosis, also known as von Recklinghousen's disease, is a genetic disorder that is inherited in an autosomal dominant pattern. This means that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition. If one parent has neurofibromatosis, there is a 50% chance of passing the condition on to each child. Therefore, the statement "Neurofibromatosis is autosomal dominant" is true.
