Description of intervention(s) / exposure
We will make our measurements prior to the procedure, which will take about 3-4 minutes as total. We will measure neck circumference, hyromental distance, sternomental distance, mandibula hyoid distance, atlantoccipital joint movement, upper lip bite test, calder test, interincisor distance, angle between upper teeth and horizontal plane and angle between mouth corner- tragus line and horizontal plane, modified mallampati score, Cormach lahane score in elective surgery ASA 1-2 patients with fixed dental prostheses and without dental prostheses
Intervention code [1] 297556 0
Not applicable
Comparator / control treatment
we will take two groups in elective surgeries. one group with fixed dental prosthesisin the front teeth and the other one control group without dental prosthesis. All ASA 1-2 groups with elective surgery 18 to 65 years
Control group
Active

Outcomes
Primary outcome [1] 301526 0
Comparison of the rate of difficult intubation between patients with and without fixed dental prosthesis on the front teeth, assessed by Cormach lahane score. Difficult intubation defined as Cormach lahane score 3 or 4.

Secondary outcome [11] 335949 0
atlantoccipital joint movement
The patient is asked to hold head erect facing directly to the front then is asked to extend the head maximally and the examiner measures the angle traversed by the occlusal surface of upper teeth using a goniometer
