[The value of restoration marginal fit as risk factor for pathological root resorption in primary teeth].

The presented clinical case describes the need for repetitive dental treatment in a child with pathological root resorption in all the primary molars after pulpotomy and composite resin restoration. Pathological resorption is of inflammatory origin in the majority of cases and an important risk factor for it is marginal leakage of the restoration. According to literature, the optimal restorative choice considering marginal fit are stainless steel pediatric crowns. Root resorption in the patient was asymptomatic. It proves the necessity for radiological control after treatment and 3, 6, 12, 24 months after it.
