Abstract

The enamel defects are some of the changes affecting persons with palatoschisis.
The aim or present paper was to describe the prevalence of enamel defects with
labial and palatine fissure, as well as its distribution by type of fissure in patients
came to Orthodontics service of Paraíba, Brazil. A cross-sectional and observational
study was conducted to collect data from the postmortem physical examination of
76 patients with palatoschisis through the unilateral and bilateral incisor foramen,
of both sexes and a mean age of 13.3 years. The examination was performed in the
upper incisor and canines by two examiners previously trained (kappa= 0.89).
Patients included were those came to service from January to June, 2011, where
the vestibular surfaces of teeth allowed a clinical assessment. Those with
malformations and no primary surgery were excluded. Data were analyzed by
descriptive statistics and Chi
 test with a significance of 5 %. The male sex
accounted for 57.9 % and the left unilateral fissure was of 40.8 %. In relation to
enamel defects, the more involved tooth was the central incisor and a diffuse
opacity for a 14.9 % followed by the presence of limited opacity for a 13.15 % and
hypoplasia for a 10.9 %. There were statistically significant differences (p< 0.00001)
between fissure and the contralateral side. Results showed the high frequency of
enamel defects in the study patients, mainly in bilateral cases and in teeth adjacent
to fissure side.
