[Dental problems in children with calcium metabolism disorders]

ABSTRACT

Calcium metabolism disorders can be acute or chronic and chronic disorders can cause different disease states such as dental problems. In this descriptive cross-sectional study done in Children's Medical Center affiliated to Tehran University of Medical Sciences during 2005-2009, all [93] patients with hypoparathyroidism, nutritional rickets, hypophosphatemic rickets and renal osteodysthrophy from the endocrinology and nephrology departments of the Center were referred to a dentist there for orodental examination. Subsequently, the frequency of dental problems including taurodontism, enamel hypoplasia, dental abscess, dental caries and gingivitis were recorded and analyzed. Nutritional rickets was the most common disorder in this study and delay in dentition was the most frequent dental problem in the patients [61.9%]. Most cases of taurdontism and enamel hypoplasia were seen in patients with hypoparathyroidism [33% and 50%, respectively]. Dental abscess, dental caries and gingivitis were more common in patients with renal osteodysthrophia [50%, 90% and 20%, respectively]. In addition, dental caries and delay in dentition were the most prevalent disorders in this study [69.8% and 49.5%, respectively]. According to the above findings, it seems that effective screening, regular periodic examinations, proper diagnosis and timely treatment of dental diseases are the main principles of prevention of orodental problems. Moreover, dentists as well as pediatricians should be aware of the features of the aforesaid disorders which lead to dental problems so that early intervention could prevent subsequent serious and more invasive dental problems
