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.

The Relationship

ABSTRACT Aim This study was conducted to assess the vertical and horizontal relationship between the maxillary sinus floor and maxillary posterior teeth roots using cone beam computed tomography. Materials and methods In this cross-sectional study, the CBCT images presented in the radiology department of Hamadan dental school was used. From 450 observed CBCT, 340 of them did not have the inclusion criteria of the study and ultimately 110 CBCT were selected. Totally 214 first premolars, 217-second premolars, 220 first molars and 220-second molars were included. For evaluating the relationship between the maxillary sinus floor and the posterior maxillary teeth, the classification implemented in the study of Jung in 2009 was used. The relation was evaluated by two radiologists twice with a 2-week time interval. Results One hundred and ten patients with a mean age of 31.06 ± 9.7 years were assessed. Type 0 relationship (the maxillary sinus floor is located above the root tip) was most frequently observed with the first and second premolars. The most common type observed in the first and second molars was type 3 (apical protrusion is seen over the maxillary sinus floor). The relation between different types and gender was statistically meaningful, while no statistically significant difference was found between the right and left side assessments. Conclusion This study showed that although most of the teeth did not have contact with the sinus floor, but the more posterior the maxillary teeth, the more probability for root protruding into the maxillary sinus. It also confirmed that protrusion of teeth roots into the maxillary sinus is more common in male than female. Clinical significance Knowing the anatomical relation between the posterior teeth and the maxillary sinus, help the clinician in preoperative treatment planning of the posterior maxillary teeth and avoid problems that may occur during dental practice.

Objectives To investigate the periapical bone thicknesses of maxillary posterior teeth at the preferred level for root resection (3 mm apical to the root end) and to determine vertical distances from apex to maxillary sinus floor (MSF) using cone beam computed tomography (CBCT) scans. Methods CBCT scans were collected from 341 subjects (2389 teeth). Associations of bone thicknesses and vertical distances with age and sex were determined by one-way analysis of variance. Results At the level of root-end resection, buccal bone was the thickest over the mesiobuccal roots of second molars (mean, 2.99 mm) and thinnest over the double-root first premolars (mean, 0.29 mm). In maxillary posterior teeth, thicker buccal bone was found in men than in women. The mesiobuccal roots of second molars were nearest to the MSF (mean, 1.33 mm), and were also most frequently extended into the sinus cavity (15.81%). Subjects more than 40 years of age had larger vertical distances from root apices to MSF in the molar region, compared with younger subjects. Conclusions Generally, periapical bone was thicker in men, and root apices were located nearer to the MSF in younger subjects. Age and sex should be considered before endodontic microsurgery.

Abstract Background The proximity of the maxillary sinus floor to the maxillary molar roots increases the probability of oroantral communication on conducting any surgical or endodontic procedure in the involved area. The aim of this study is to evaluate the relationship between each maxillary molar root and maxillary sinus floor using cone beam computed tomography. Predicting the probability of protrusion of each root into the sinus will consequently predict the probability of occurrence of the oroantral fistula in a sample of the Egyptian population. Results The total number of roots located outside the sinus was 121 (35.3%), while those contacting the sinus floor were 80 (23.3%) and those intruded the sinus were 141 (41.2%). The percentage of root intrusion into the sinus in males (56.9%) was significantly (p = 0.01) higher than females (42.9%). The probability of root intrusion in the left molars (54.2%) was non-significantly (p = 0.067) higher than that of the right side (44.3%). As for the type of tooth, the second molar showed the highest probability of root intrusion into the sinus (55.3%) followed by the third molars (52.6%) then the first molars (40.9). According to the type of root, the mesiobuccal root showed the highest probability of intrusion into the sinus (50.9%) followed by the palatal root (49.1%) then the distobuccal root (47.4%). However, the difference in both type of tooth and type of root was statistically non-significant (p = 0.051 and 0.869 respectively). As for the individual root with the highest probability of intrusion, the mesio-buccal root of the right third molar is the most frequent root to intrude the sinus (71.4%) and the mesio-buccal root of the right first molar is the least frequent (22.7%). Conclusions In a sample of the Egyptian population, males exhibit higher probability of root protrusion into the sinus than females. The side and type of tooth are of higher impact on the probability of its intrusion into the sinus compared to the type of root. Left second molars are at a higher risk of oroantral communications on surgical or endodontic procedures compared to other molars due to its highest probability of intrusion into the sinus.
