Evaluation of aggressive pulp therapy in a population of vitamin D-resistant rickets patients: a follow-up of 4 cases.

This investigation collected clinical and radiographic data from a retrospective chart review of 4 patients receiving prophylactic formocresol pulpotomies and stainless steel crowns following a dental abscess associated with a medical diagnosis of vitamin-D resistant rickets (VDRR) at Texas Scottish Rite Hospital for Children in Dallas, Tex. Clinical and radiographic data were available for 29 primary teeth in 4 children, with follow-up times ranging from 2 years, 1 month to 5 years, 6 months. Based on available recalls of 29 teeth treated following the prophylactic formocresol pulpotomy, 22 failed clinically. The earliest failure occurred at 3 months; the longest time to failure was 3 years, 9 months. No trends were discernable between tooth type and failure rate, although the shorter the time between eruption of the tooth and pulpotomy treatment, the greater the chance of success. Presently, there is not enough evidence to suggest that prophylactic pulpotomy therapy in VDRR patients is beneficial in preserving their primary dentition.
