Erythroblastosis fetalis (hemolytic disease of the newborn) causes hyperbilirubinemia leading to bilirubin deposition in developing teeth. This results in characteristic pigmented teeth with green, brown, or blue discoloration. The pigmentation occurs due to biliverdin and bilirubin incorporation into the dentin and enamel during tooth development. Dentinal dysplasia and hypoplastic teeth are not typical features of erythroblastosis fetalis.

The paralleling technique in intraoral periapical radiography is based on the principle of using parallel lines and right angles to produce an accurate image of the tooth structure.This method requires the image receptor (film or sensor) to be positioned parallel to the long axis of the tooth being radiographed.To prevent image distortion (magnification or foreshortening), the central ray of the X-ray beam is then directed perpendicularly to both the image receptor and the long axis of the tooth.
