[Updates on rickets and osteomalacia. dental diseases in rickets].
Rickets is characterized by mineralization defect in bone and cartilage. X-linked hypophosphatemic rickets (XLH) is the most common form of inherited rickets. Mineralization defect is observed in dentin as well as in bone and cartilage in XLH. The dominant feature is the occurrence of infectious periradicular abscesses on deciduous and permanent teeth, not associated with trauma or decay. Dental care including the maintenance of good oral hygiene and periodical examinations should be performed. A preventive sealing of occlusal surfaces can be considered. Endodontic treatment or extraction are carried out in the presence of periradicular abscesses. Further studies are necessary for elucidating mechanisms of dentin mineralization defect and the occurrence of periradicular abscesses and for developing preventive and curative measures in XLH.
