Displacement of maxillary right second premolar caused by gutta percha filling in corresponding primary molar

Background

For pulp therapy in primary teeth, commonly performed in daily clinical practice, calcium hydroxide paste is widely used as a root canal filling material and typically resorbed by the permanent successor upon its emergence into the oral cavity.

Case report

A 21-year-old female was referred to our clinic for detailed examination of a residual maxillary right primary second molar. After extracting that tooth, a material thought to be gutta percha was unexpectedly extirpated.

Conclusion

We speculated that the material had prevented eruption of the permanent successor because of lack of resorption, leading to its displacement.
