    Can someone help answers the questions below and also explain the reason. thanks!!

    A 42-year-old female with a history of hyperparathyroidism presents with a complaint of bilateral pain in the temporomandibular joint on closing. She reports that her ears are occasionally “clogged”, and she sometimes experiences a “ringing” sensation. The dentist determines that these symptoms are related to her TMJ condition.

    363. Which of the following will most likely be increased in this patient?
    A intestinal calcium absorption
    B intestinal organic phosphate absorption
    C renal calcitriol production
    D renal calcium excretion
    E renal organic phosphate excretion

    365. Examination reveals diminished parotid salivation due to middle ear involvement. Which of the following nerves is MOST likely involved?
    A facial
    B Lesser petrosal
    C Greater petrosal
    D Auriculotemporal
    E Chorda tympanic

    366. In this patient, which of the following regions of the articular surface of the TMJ is unlikely to be present?
    A Calcified cartilage
    B Subarticular bone
    C Proliferative zone
    D Fibrous articular layer
    E Fribrocartilaginous zone

    367. If the patient’s sensation of “clogged ears” is due to pressure on the auditory tubes, then which of the following nerves is providing this sensory invervation?

    A Glossopharyngeal
    B Lesser occipital
    C Vestibulocochlear
    D Zygomatic temporal
    E Posterior deep temporal

    A 10-year-old female with a history of acute lymphoblastic leukemia is undergoing orthodontic treatment that is complicated by poor oral hygiene. Oral examination reveals generalized cervical plaque and enlargement of the gingival. There is generalized bleeding on probing.

    372. If this patient’s leukemia contributed to increased intraoral bleeding, then the increase is most likely due to which of the following condition?
    A anemia
    B Leukopenia
    C Ca++ deficiency
    D Thrombocytopenia
    E Factor VIII deficiency

    A patient with hepatitis C is scheduled for extraction of posterior teeth in the right lower quadrant due to advanced periodontal disease. Tooth #28 is abscessed and draining into medical soft tissue. Tooth # 30 shows a large carious lesion and is painful.

    399. If the patient and dentist elect to extract Tooth #30, sectioning of the tooth will be required. The dentist should be aware of which of the following furcations on the tooth?
    A one
    B Two – mesial and distal
    C Two – facial and lingual
    D Three - mesial, distal and facial
    E Three – facial, mesial, and lingual

    in hyperparathyroidism shouldnt the calcium excretion decrease?
    i thought ans would be A
    plz explain

    You are right, my bad. I was thinking about tooth sectioning.
    You are Correct.

    the answer is A....i guarantee it.

    PTH increases renal tubular reabsorption of Ca (therefore, a decrease in renal calcium excretion) and increases intestinal Ca absorption (choice A).

    this is why you should look up the answers to your own questions when studying and not rely on SDN.

    A person with tooth-ache, fever , diffuse,firm facial swelling n has neutrophillic leukocytosis . the facial swelling is due to
    a. granulomatous inflammation
    b . cellulitis

    Sterile cutaneous manifestations [rashes] are seen in all except
    a. scarlet fever
    b. rheumatic fever
    c. tertiary syphilis
    d. meningiococcal meningitis

    even I'll go for increased renal calcium excretion becoz intestinal calcium absorption is the predominant function of vit D and PTH just assists with vit D in this function ..... PTH function is no doubt increased calcium absorption by kidney but when serum calcium increases beyond limits as in hyperparathyroidism , renal calcium excretion occurs

    Can you please tell me from where did you get all these questions? Is this from any book? I need to work on clinical questions as well. But could not find anything to read other than decks.

    The answer s'd be increased intestinal ca+2 absorption. The last option is not correct as it s'd be inorganic PO4-3 excretion and not organic. Hope this helps.
