Relationship between posterior teeth apices and maxillary sinuses floor observed by panoramic radiography and cone beam CT
Summary:
The relationship between the apices of the posterior teeth and the sinus floor is important because of the complications, which we want to predict.
The complications are related to implant placement, apical lesion pathology, root fracture, periapical surgery, oroantral communication etc.
All specialties of clinical dentistry as orthodontics, pediatric dentistry and endodontics may experience such complications.
The aim of this study is to compare two imaging modalities i.e. panoramic radiography (PR) and cone beam CT (gold standard technique) regarding the maxillary sinus and posterior teeth apices.
71 patients, men and women from 18 to 78 years old, were retrospectively examined by our archives (PR and cone beam CT examinations).
Score 0 refers to a clear distance between teeth apices and sinuses, found to be in 170 teeth. The most founded score.
Generally between the two imaging modalities we found agreement in 217 teeth. That means 53.5% general agreement.
In cases where the teeth apices-sinuses space is great, PR is sufficient in 98,3% of the cases.
The benefit of PR is reduced in case where the space is low (86,1%) and also where the teeth apices appear to be either buccal or palatial of maxillary sinus (88,4%).
When the teeth apices are inside the sinuses (score 3) the PR is not useful as an imaging tool (just under 2% accuracy).
In conclusion, PR can be reliably recommended only in cases of score 0
