Abstract This study evaluated the anatomical relationship between posterior teeth root apices and maxillary sinus floor (MSF) on 202 cone beam computed tomography (CBCT) exams. The distance between the root apices and the MSF, as well as the MSF thickness of the cortical bone closest to root apices and furcation regions were measured. The vertical and horizontal relationships of the MSF with the molar roots were classified into categories adapted from the criteria proposed by Kwak et al. (14). The shortest distances between MSF and the root apices were observed in the mesiobuccal root of the second molar (0.36±1.17 mm) and the palatal root of the first molar (0.45±1.10 mm) and the widest in buccal roots of the first premolars (5.47±4.43 mm). Significant differences were observed between the distance of MSF to the root apices of single-rooted first and second premolars. The cortical thickness ranged from 0.65±0.41 mm over the mesiobuccal root of the second molar to 1.28±0.42 mm over the buccal root of the first premolar. The most observed vertical and horizontal relationships were type II and 2H, respectively. The maxillary molar roots showed greater proximity to the MSF. The thickness of the MSF cortical bone closest to the apices and furcation regions was found to be similar only for premolars.

Objective This study aimed to assess the positional relationships between the maxillary sinus and the first and second molars in a western Chinese population by using cone-beam computed tomography. Methods This study included 212 patients (652 maxillary molars and 1956 roots). Patient demographics (sex and age) and cone-beam computed tomography data regarding the relationship between molar roots and the maxillary sinus were obtained. This relationship was stratified into four types for statistical analysis. Results Sex and side did not significantly influence the distance between maxillary molar roots and the maxillary sinus. However, the distance between maxillary molar roots and the maxillary sinus increased with age. The mesiobuccal root of the second molar was nearest to the maxillary sinus. The most common relationship type involved absence of root contact with the sinus border and presence of a maxillary sinus cross-section above the root apex. Conclusions Compared with other teeth, the maxillary posterior teeth have a complex anatomical structure and are closely related to the sinus. These findings may serve as reference information for root canal treatment, tooth extraction, dental implant, and other dental clinical procedures among patients in western China.

Significant Difference

The aim of the study was to determine the range of maxillary sinus volume and linear dimensions in adults, taking into account the gender and the side of the location using cone-beam computed tomography (CBCT) images.This study used the CBCT images of 136 patients (263 maxillary sinuses), who were presented to Minsk health facilities, with dental and maxillary sinus pathologies, aged over 20 years with no history of upper jaw surgery and with the presence of upper posterior teeth (from the first premolar to the second molar inclusive). The height, depth and width of the sinus weremeasured manually on CBCT scans. The maxillary sinus volume (V) was calculated by the formula: V = height × depth × 1/3 width.The volume of the maxillary sinus was varied from 5.53 to 24.03 cm3. The mean values of the sinus width, height and depth were 27.13 ± 3.83 mm, 35.83 ± 4.36 mm, and 38.98 ± 3.38 mm respectively.Despite a high variability of the maxillary sinus volume values, we did not find a statistically significant difference between the right and left sides in both males and females. The maxillary sinus linear dimensions and volume in females were statistically significantly less than in males.
