Reliability of fovea palatinea in determining the posterior palatal seal

Abstract EN

Background : the present study was carried out to study the position of fovea platinae in relation to posterior palatal seal (post dam) in an Iraqi, population sample, whether in front, at or behind, and gender differentiations.

Material and methods : A clinical examination was carried out on 200 patients with edentulous maxillary arch, attending prosthetic Department in the College of Dentistry, Baghdad University.

Only 110 patients meet the study's criteria.

Each patient was examined for the location of vibrating line whether in front, at or behind the fovea platinae Results : The results showed that 50.9 % of patients had their vibrating line at their fovea platinae, 44.5 % had it in front and 6.4 % behind.

There were highly significant differences between ; age groups of patients, gender distribution of patients, significant differences between; age group and gender of patients, and non-significant differences between gender and position of posterior palatal seal in relation to fovea palatinae.

Conclusion : the study concluded that fovea palatinae is : A reliable anatomical land mark that helps in determining the posterior palatal seal (post dam).

The majority of patients had their vibrating line at their fovea palatinae.
