However, a large midline diastema in the primary dentition may indicate thepresence of an unerupted midline supernumerary tooth (mesiodens - only if between central incisors) and often warrants an appropriate radiograph. The permanent maxillary central incisors erupt labial to the primary incisors and often exhibit a slight distal inclination that results in a midline diastema. This midline space is normal and decreases with the eruption of the lateral incisors. Complete closure of the midline diastema, however, does not occur until the permanent canines erupt. Treatment of residual midline space is addressed orthodontically at this time.Diastema in mixed dentition before eruption of canines is normal.Activator/Bionator is used for: Class II + DeepbiteWhat is the space maintainer of choice for a 7-year-old child who has lost a lower primary second molar to caries?

A 25-year-old woman presents with the chief complaint of spontaneously bleeding gingiva. She also notes malaise. On oral examination you find that her hygiene is excellent. Would you suspect a local or systemic basis for her symptoms? What tests might you order to make a diagnosis?Answer: Spontaneous bleeding, especially in the face of good oral hygiene, is most likely of systemic origin. Gingival bleeding is among the most common presenting signs of acute leukemia. Management: Medical evaluation and lab tests2. A 60-year-old woman presents with the complaint of numbness of the left side of her mandible. Four years ago she had a mastectomy for treatment of breast cancer. What is the likely diagnosis? What is the first step you take to confirm it?Answer: As the metastatic lesion grows, it puts pressure on the inferior alveolar nerve and causes paresthesia.5. A patient presents for extraction of a carious tooth. In taking the history, you learn that the patient is receiving chemotherapy for treatment of a breast carcinoma. What information is critical before proceeding with the extraction? Answer: The major organ system affected by cytotoxic chemotherapy is the hematopoietic system. Patient’s white blood cell count and platelet count before initiating treatment and in consultation with physician.6. What oral findings have been associated with the diuretic hydrochlorothiazide?Answer: Lichen Planus7. What is the minimal acceptable platelet count for an oral surgical procedure?Answer: Normal platelet count is 150,000—450,000. In general, the minimal count for an oral surgical procedure is 50,000 platelets. However, emergency procedures may be done with as few as 30,000 platelets.8. Should oral surgical procedures be postponed in patients taking aspirin?Answer: Elective procedures, if at all possible, should be postponed in the patient taking aspirin.9. What are the considerations in treating patients infected with the HIV virus and treated with azidothymidine (AZT)?Answer: Patients taking AZT should have a CBC every 2 weeks. Before oral surgical procedures, a CBC should be done to determine whether the patient is neutropenic or thrombocytopenic10. A patient with HIV infection requires an oral surgical procedure to remove teeth after severe bone loss due to H1V-related localized periodontitis. What precautions should be taken?Answer: It is estimated that 10—15% of patients with HIV develop immunogenic thrombocytopenic purpura (ITP). The anti-platelet antibodies appear to be found more frequently in advanced stages of the disease. Affected patients should have a CBC before any oral surgical procedure. If the platelets are low (below 150,000), the procedure should be done only after consultation with the patient’s physician and with the knowledge that bleeding may be increased. The patient may require platelet transfusions to control postoperative bleeding.12. Is it safe to treat a patient who has had a heart transplant in an outpatient dental office?Answer: The patient most likely will be taking prednisone and cyclosporine. Erythromycin and ketoconazole inhibit the metabolism of cyclosponine.13. Hypothyroid patient?Answer: Dental care should be deferred until after a medical consultation.14.
