Endodontic treatment in primary teeth can be challenging and time consuming, especially during canal preparation, which is considered one of the most important steps in root canal therapy. The conventional instrumentation technique for primary teeth remains the “gold-standard” over hand instrumentation, which makes procedures much more time consuming and adversely affects both clinicians and patients. Although the manual preparation techniques still remain the standard measure of biomechanical preparation, it has certain shortcomings such as several iatrogenic errors including the ledging, zipping, canal transportation, and apical blockage. The nickel–titanium (NiTi) rotary instruments came into existence in the field of endodontics to overcome these shortcomings of conventional manual file system and have presented desired outcome with their efficient cleaning of the root canal maintaining the original canal space during BMP procedure. However, the bizarre root canal morphology and thinner root dentin limited the use of rotary endodontics in primary teeth. To overcome such barriers, various modified protocols have been introduced to prevent any undesirable complications. The preservation of vitality in young permanent teeth via pulp capping and pulpotomy is paramount until root formation is completed.
