Abstract :
I read with interest Rabbani et al’s paper entitled
“Dental problems in hypophosphatemic rickets, a
cross sectional study” in the fourth issue of Iran J
Pediatr 2012[1]. Clinical oral manifestations of
hypophosphatemic rickets often include
premature tooth exfoliation, hypoplastic enamel
and dental infections. Apical rarefaction, rickety
bone trabeculation and absent or abnormal lamina
dura are frequent radiographic findings[2].
Single or multiple abscesses relate to the
enlarged pulp chamber and pulp horns reaching
the dentino-enamel junction or even the external
surface of the tooth[2, 3]. Defective enamel is also
abraded or fractured easily[2]. Prophylactic
pulpectomy and stainless steel crown placement
have been recommended in affected patients[2,3].
Since premature tooth exfoliation is sometimes
a feature in this inherited abnormality[2], the paper
could also be paid to the investigation of this case.
Also in the mentioned article, it is not clear under
what circumstances the oral examination was
done and what index has been used to assess the
inflammation of the gingiva.
