“…It was followed by types II and III relationship with much less percentage (8.96% and 6.05%, respectively). This order was in accordance with a recent study by Oishi et al [20]. They de ned type 0 for those cases in which sinus oor did not appear above the root apices.…”

“…Oishi et al [20] found a negative correlation between the distance of maxillary sinus oor to the root apices of all teeth (posterior teeth and canine) and age in CBCT images. The same result was found by AL Qasab et al [22] regarding the distance between the canine apex and maxillary sinus oor in periapical radiographs.…”

“…Their study also included the anterior teeth with apical lesions. To the best of our knowledge, only one comparable study has been published recently which evaluated the relationships between the maxillary teeth (molars, premolars, and canine) and maxillary sinus oor in CBCT [20].…”

“…The relationship between the maxillary sinus oor and posterior teeth has already been evaluated in various studies [4,[10][11][12][13][14][15][16]. In contrast, few studies have addressed the relationship between the maxillary sinus oor and canine apex [4,[20][21][22]. AL-Qasab et al [22] evaluated this relationship in a limited sample size (30 individuals) and in periapical radiographs.…”

“…To the best of the authors' knowledge, there are only few CBCT studies regarding the relationship of the anterior teeth and maxillary sinus [20,21]. Therefore, the aim of the present study was to assess the location of the anterior border of the maxillary sinus in relation to the teeth and amount of anterior extension of the maxillary sinus (AEMS) beyond the canine tooth long axis.…”

Background: The purpose of the present study is to investigate the frequency and amount of extension of the maxillary sinus to the anterior region and to evaluate the vertical distance between the maxillary sinus floor and canine apices.Methods: Cone beam computed tomographic images of 300 individuals (154 males and 146 females) over 20 years (with mean age of 35.12 ± 8.40 years) were evaluated. The subjects were categorized into three age groups (20-30, 30-40 and 40-50 years). When maxillary sinus extended to the canine area, the vertical distance between them were recorded and their relationship were classified into three types: I (> 2 mm distance), II (2 mm < distance or in-contact) and III (interlock). Results: 413 out of 600 maxillary sinuses (68.8%) were extended into the canine area or beyond. Among them, 15 maxillary sinuses pneumatized into the incisor area (2.5%). The prevalence of the maxillary sinuses extended to the anterior region of the jaw was not significantly different between genders, but it was significantly less frequent in older age group and more frequent in the left side. The mean amount of anterior extension of maxillary sinus (mm) was significantly lower in older age group. Type I was the most frequent vertical relationship between the maxillary sinuses and canine apices with no significant difference in gender, side and age groups.Conclusions: Most of the maxillary sinuses extended to the canine area. Maxillary sinus extended into incisor area with the frequency of 2.5% . The amount of extension of the maxillary sinus to the anterior region and its vertical distance with canine apices decreased in older age group.
