When interpreting dental radiographs for caries, which section of the tooth surface should be examined for evidence of proximal caries?
A) Just above and just below the enamel on the occlusal surface
B) Just apical to the occlusal surface at the contact point of adjacent teeth
C) At and just apical to the contact point of adjacent teeth
D) At and just apical to the gingival margin between adjacent teeth

Proximal caries can be detected by examining the area at and just apical to the contact point of adjacent teeth on dental radiographs. This is because this area is prone to plaque accumulation and is difficult to clean with oral hygiene measures, making it vulnerable to caries development. Examining just above and just below the enamel on the occlusal surface (A) may not reveal proximal caries, while examining just apical to the occlusal surface at the contact point of adjacent teeth (B) may not provide a comprehensive view of the proximal surface. Examining at and just apical to the gingival margin between adjacent teeth (D) may show evidence of caries, but this area is less commonly affected by proximal caries compared to the area at and just apical to the contact point.
