What might be indicated by finding multiple retained roots on a radiograph?

Finding multiple retained roots on a radiograph typically suggests the potential need for extraction of those roots. Retained roots can occur when a tooth is non-vital or has undergone trauma while the roots remain embedded in the alveolar bone. If these roots are left untreated, they could lead to various complications, including infection or other dental pathologies. Thus, the presence of multiple retained roots often leads the clinician to consider extracting them to prevent such issues.

While the other options may seem relevant in some contexts, they don't directly address the primary implication of multiple retained roots. Endodontic treatment is typically indicated for vital teeth or those showing signs of pulp involvement. Intact primary teeth do not typically correlate with multiple retained roots, as retained roots often pertain to permanent teeth. Cyst formation can occasionally be associated with retained roots, but it’s not a direct indication and may not always occur in these situations. Therefore, the finding of multiple retained roots is most closely aligned with the consideration of extraction to prevent further complications.
