Oral Medicine & Radiology — Key differences for NEET MDS
OPG = orthopantomogram most common extraoral radiograph. Bisecting angle technique causes foreshortening or elongation. Paralleling technique = more accurate positioning = XCP holder. CBCT = cone beam CT = 3D imaging = gold standard implants TMJ. kVp controls quality and contrast. mA controls quantity and density. ALARA principle = as low as reasonably achievable.

Osteoradionecrosis = mandible more than maxilla = avascular necrosis. Trismus = late complication fibrosis. Wait 6 months minimum post-radiation for extractions. HBO = hyperbaric oxygen adjunct for ORN treatment. Radiation caries = cervical smooth surface pattern.
