Question Answer
(good/bad prognosis?) distinct bordersgood
(good/bad prognosis?) indistinct bordersbad
these can mimic pathologic conditions, but you can tell what they are (and be relieved) because they will be bilateral, well corticated, and in patients that are young with a mixed dentitionEarly Stage Tooth Crypts
how long should it take extraction sites to remodel (and fill in)6-12 months
how long into extraction socket healing does socket gets full with blood clot which solidifies and starts to remodelfirst hour
around _________ days after extraction you start seeing granulation tissue around the site.2 days
Granulation tissue in a healing extraction socket becomes young vascular ____ tissueFibrous
New bone (which still appears moderately radiolucent) appears in the healing extraction socket around day ____day 52
Hemopoietic bone marrow normally occurs in the jaws where in mandible and where in maxillaAngle of mandible; maxillary tuberosity
Focal Osteoporotic Bone Marrow defects can be normal and not pathological, the best way to determine is what?compare to other side. if bi-lateral then likely not pathologic
what common cause when Bone fails to fill in at extraction sites, instead Red or fatty marrow fills area (and its asymptomatic)Focal Osteoporotic Bone Marrow Defect
Focal Osteoporotic Bone Marrow defect with failure of fill at extraction sites ... poorly defined or well defined periphery?poorly defined (in this instance because it does not elicit a response from surrounding bone bc it's not pathologic)
If the cortical plate and periosteum are destroyed by a pathologic condition or by extensive surgery, the periosteal source of osteoblasts is lost what type of defect could result?Fibrous Healing Defect
Apical Radiolucency that resembles periapical pathology, with punched out appearance and often follows apicoectomy.... however is asymptomatic and does not change over timeApical Scar
T/F: An apical scar has loose collagen and many fibroblastsFalse (dense and few)
T/F: An apical scar has dense collagen and few fibroblastsTrue
Developmental inclusion of salivary gland tissue within, or more commonly, adjacent to the lingual surface of the mandible in cortical bone creating a radiolucency below the inferior alveolar canalStafne Bone Defect (aka developmental lingual salivary gland defect)
T/F: Stafne detect (salivary gland developmental defect) can be distinguished from pathology based on whether or not it is bilateralFalse (often unilateral)
what type of imaging can be used to confirm Stafne defect?Sialography (see if salivary gland is in that space)
T/F: it is acceptable to biopsy a potential Stafne defectTrue
Develops through cystic degeneration and liquefaction of the stellate reticulum in the enamel region before calcified enamel and dentine has been formedOdontogenic Keratocyst
Solitary, well circumscribed radiolucent lesion that is asymptomatic that Arises in place of normal or supernumerary teeth in younger patientsOdontogenic Keratocyst
memorize
Developmental odontogenic cyst located along the lateral surfaces of the teeth
