Pediatric dentistry does not limit itself to the dentition and soft tissues that are easily visible in children's mouths. It also involves those structures that are hidden, cryptic, and frequently remain undiagnosed. One such example is the spare roots in molars, which is a fascinating demonstration of anatomic root variation. It is acknowledged that both the deciduous and permanent mandibular first molars usually have two well-developed roots, one mesial and one distal root. Occasionally an additional third root is seen. It is termed as radix entomolaris (RE) when it is located distolingual to the main distal root and termed as radix paramolaris (RP) when it is located mesiobuccal to the mesial root. This case report highlights the importance of a full-fledged clinical and radiographic evaluation preceding the treatment. It also covers the necessity of evaluating a radiograph in different angulations. Here this case report deals with the usage of the SLOB technique, endodontic treatment, and maintaining tooth durability using a stainless steel crown (SSC).
