PURPOSES: The present study was conducted to assess the amount of bone present
between root apices and the maxillary sinus floor in the maxillary lateral
region, to compare the evaluations on cone beam computed tomography (CBCT) and
orthopantomography (OPG), and to evaluate the bone density of the same region
using three-dimensional images on CBCT. METHODS: Fifty-one dental patients were
recruited for the study. All subjects were partially edentulous. The distances
from the maxillary premolars and molars apices to the maxillary sinus floor were
assessed using CBCT and OPG. Color codes were assigned to the bone density of
edentulous loci. Parametric and non-parametric tests were used for statistical
analyses. A p value <0.05 was considered statistically significant. RESULTS: The
maxillary first and second molars recorded the shortest mean distances to the
sinus floor, in contrast to the maxillary first premolar. The bone density of the
maxillary lateral area increased from the maxillary first premolar to the second
molar. No statistical significant differences were found between the evaluated
sites. CONCLUSIONS: Our results provide estimates of the minimal and maximal
distances between teeth and sinus, as well as the average bone density in the
maxillary lateral region. It is important that evaluation of a specific patient
be performed during the preoperative planning of implants.
