While we carry out oral management annually in treating pediatric patients, we may frequently encounter unexpected events. One of them is the case in which the dental pulp becomes inflamed for some reason, leading to early abnormal root resorption. In the deciduous molars particularly, despite the long time needed for the period of changing dentition, only one root may show almost completely root resorption while the other roots are healthy. According to the routine method, such a case should be treated by tooth extraction and the use of a space maintainer. However, there may frequently be some cases in which we hesitate to use such treatment. If a tooth under this condition is preserved, it will be very difficult to fill a root canal using a paste-type root canal filling material and to maintain the tooth until the dedentition, because of obliteration of the root canal. I performed root canal filling using Obturation Gutta for the root with abnormal resorption and a paste-type root canal filling material (Sealapex) for the other roots without resorption. I have been obtaining good results by using Obstration Gutta that enabled preservation of the teeth which have been considered difficult to preserve and their maintenance until the period of changing dentition, owing to the only slight biostimulation and the dense obliteration of the root canal by the material.
