periapical radiolucency on a non-vital tooth
dental (periapical) granuloma, It represents one of two forms of chronic apical periodontitis, the other being the radicular cyst. There is no method by which these two entities can be distinguished clinically or radiographically. Only biopsy can discriminate
what are the histopathologic features that charaterize the OKC
- Keratin in the lumen
- Parakeratinized stratified squamous epithelial lining
- lining of uniform width about 6-8 cell layers thick
- a wavy or corrugated silhouette to the epithelial surface
- Nuclei in the basal layer are polarized into a tombstone or picket fence arrangement,
- absence of rete pegs
- satellite or daughter cysts are common
medication/treatment for Aphthous ulcers
Steroids and antibiotics, APHTHASOL, Betamethasone, Temovate, Lindex
med/txt for recurrent oral herpes
antiviral meds: Acyclovir ointment or capsules
- Famciclovir, penciclovir
- prodromal stage is best time to start treatment
Mixed Radiolucent/Radiopaque Lesions:
- Florid Cemento-Osseous Dysplasia
- periapical cemento-osseous dysplasia
- Chronic Osteomyelitis
Deep carious lesion or large restoration
Nonvital tooth
Organisms not virulent, host defenses strong
Reaction of host bone to “wall off” products of inflammation
Lesion of bone, not of tooth
Condensing Osteitis, radiopaque lesion
Asymptomatic
Middle-aged African-American females
3 maturational phases (RL, RL with RO foci, RO)
RCT NOT NECESSARY!
BX NOT NECESSARY! Exposure of lesions can result in osteomyelitis superimposed on dysplastic bone
Mixed Radiolucent/Radiopaque Lesions: Periapical Cemento-Osseous Dysplasia

hyperparathyroidism
Thorough curettage, surgery
Steroids, calcitonin, interferon alfa 2a
