Abstract:

Pneumatization of the maxillary sinus leads to posterior root displacement into the sinus cavity associated with potential complications following extraction of these teeth.
Objectives. The aim of the present study is to assess the relationship between the apices of maxillary posterior teeth and the floor of the maxillary sinus.
Materials and methods.The study involved a retrospective randomized analysis of 245 scans of the maxilla, 465 scans of sinuses and 960 scans of teeth and their relationship to the maxillary sinus. The distance between root apices and the maxillary sinus floor was measured and the measurements featured canines, premolars and molars.
Results. 746 teeth, out of the 960 teeth examined, were in dangerous proximity to the maxillary sinus, 156 of which penetrated the sinus cavity at different depths.
Conclusions. In patients from the Varna region maxillary second molars appeared to be the most common teeth to project into the sinus and when extracting these teeth dental clinicians must be particularly cautious for possible complications related to this problem.
