DMP1 and autosomal recessive hypophosphatemic rickets: Similar positive effects of Scl-Ab on alveolar bone were observed in the DMP1 null mouse model of autosomal recessive hypophosphatemic rickets (ARHR).40 However, unlike the current study, the authors report that Scl-Ab improved the cellular cementum and PDL organization, although it is worth noting that these effects were not compared quantitatively, as in the current study.
