In endodontic radiography, which description indicates an adequately filled root canal?

• A. Filling extends beyond the apex
• B. Filling reaches the apex with proper length, density, and no voids or overfill
• C. Filling short of the apex
• D. Filling with voids

Answer: (B)

An adequately filled root canal on a radiograph shows the obturation material ending at the apical area with proper length, density, and no voids or overfill. Reaching the apex ensures the entire canal is sealed to the apical constriction; the fill should be dense and homogeneous, without gaps, so there’s a continuous seal along the canal. If the material goes beyond the apex, it can irritate surrounding tissues; if it ends short of the apex, part of the canal remains unfilled. Voids within the fill indicate an incomplete obturation, which compromises sealing and can harbor bacteria. When these criteria are met, the canal is considered adequately filled.
