تقييم الارتباط بين البعد العمودي الإطباقي وبين طول الإبهام و المسافة بين زاويتي الفم عند المرضى الدرد و ذوي الأسنان الطبيعية

الملخص EN

Background & Aim : The aim of this study was to compare the distance between the two corners of the mouth, length of the thumb and the vertical dimension of occlusion (Sn Me) in edentulous and dentate patients in the Syrian society.

Materials and Method : This cross-sectional study included 200 patients : 100 were dentate (G1), and 100 were completely edentulous (G2).

The vertical dimension of occlusion (Sn-Me) was measured using willis gauge in G1 and G2.

Length of the thumb and distance between the two corners of the mouth were measured using a calliper.

Patients in G2 were asked to close in the physiologic rest position during measurements whereas the patients in G1 closed in the centric occlusion position.

Result : This study revealed that there is a correlation between the occlusal vertical dimension and the distance between the two corners of the mouth and the length of the thumb, but this correlation was weak.

The correlation between the occlusal vertical dimension and the distance between the two corners of the mouth was in the group of edentulous patients (r = 0.31), and in the group of dentate Patients (r = 0.27).

The correlation with the length of the thumb in the group of dentate Patients was (r = 0.31), and in the group of edentulous patients was (r=0.26).

Conclusion : It is not possible to depend on the distance between the two corners of the mouth and the length of the thumb in predicting the occlusal vertical dimension in edentulous and dental patients in the Syrian society.
