Q

describe the pyogenic granuloma

A
  • not an actual granuloma as there is proliferation of vascular tissues as well as proliferation of fibrous tissue
  • forms submucosally and takes the shape of a nodular growth
  • though to be exacerbated response to plaque and bacteria precipitated by the changes in hormonal levels

Q

what are the general dental guidelines during pregnancy and in each trimester

A
  • take a history of the trimester and note complications and BP
  • first trimester: fetus is especially susceptible to teratogenic influence and abortion
  • second trimester: optimal trimester for dental care
  • third trimester: syncope and hypertension risk are greatest secondary to fetal position. cardiovascular demands are greatest, there is increased risk of anemia, the highest risk of eclampsia, and increased risk of hypertension

0.01mGy

31
Q

an absorbed dose to the conceptus of ____ doubles the natural childhood cancer rate from 1 in 500 to 1 in 250

A

25mGy

32
Q

absorbed dose of _____ increases the childhood cancer rate to 1 in 375

A

12mGy

33

388 micro SV

38
Q

what is the effective dose for the fetus for pano radiographs

A

9-26 micro Sv

39
Q

what is the effective dose for the fetus for CBCT

A

20-599 micro Sv

40
Q

what is the recommendation for radiographs for pregnant pts

A

contraindicated in all but emergency situations. when taken lead shielding is necessary

41
Q

what is the protocol for new and recall pregnant dental patients

A
  • radiographs should be postponed until post partum
  • long term benefit to the health of the mother from new patient or recall exam radiographs
  • BUT no benefit to the health of a developing child
  • unborn child faces greater risks from the radiation exposure than the mother without any benefit to their health
42
Q

what does the national council on radiation protection and measureemnts recommend

A

different radiation exposure thresholds for pregnant radiation workers than non pregnant radiation workers
- radiation exposure thresholds for pregnant radiation workers is lowered to the same thresholds as the general population

43
Q

what is the SoD recommendation for guidelines for pregnant patients

A

same as NCRP recommendations

44
Q

what is the patient shielding protocol during dentomaxillofacial radiology

A
  • discontinuing shielding of the gonads, pelvic structures, and fetuses during all dentomaxillofacial radiographic imaging procedures
  • thyroid shielding not be used during intraoral, panoramic, cephalometric and CBCT imaging as the risks of thyroid cancer are negligible from comtemporary maxillofacial imaging radiation doses
45
Q

what is the radiograph protocol for emergency dental patients

A
  • necessary radiographs are part of the standard of care to treat and dx a condition that threatens the health of the mother and the unborn child
  • lack of radiographs compromises the emergency care dx and tx, this will directly impact the health of the unborn child
  • primary beam is not directed toward the child bearing area
46
Q

what are the protocols for medication

A
  • there should be medical clearance for all drugs including LA, analgesics, and ABs
  • lidocaine, penicillin, erythromycin, and acetominophen are generally approved
  • aspirin and vasoconstrictors in LA and all drugs causing respiratory depression are relatively contraindicated
  • diazepam, nitrous, and tetracyline are absolutely contraindicated
