“…28,29,30 CBCT scans are preferred because they are more convenient and simpler from ethical, economical and technical points of view. The use of this approach circumvents the need to dissect Malay cadavers, which is a practical issue because they are impossible to obtain due to religious practice.…”

The objective of this study was to measure the topographic thickness of the lateral wall of the maxillary sinus in selected Asian populations. Measurements were made on the lateral walls of maxillary sinuses recorded using CBCT in a convenient sample of patients attending an Asian teaching hospital. The points of measurement were the intersections between the axes along the apices of the canine, first premolar, and second premolar and along the mesiobuccal and distobuccal apices of the first and second molars and horizontal planes 10 mm, 20 mm, 30 mm and 40 mm beneath the orbital floor. The CBCT images of 109 patients were reviewed. The mean age of the patients was 33.0 (SD 14.8) years. Almost three quarters (71.8%) of the patients were male. The mean bone thickness decreased beginning at the 10-mm level and continuing to 40 mm below the orbital floor. Few canine regions showed encroachment of the maxillary sinus. The thickness of the buccal wall gradually increased from the canine region (where sinus encroachment of the canine region was present) to the first molar region, after which it decreased to the thickness observed at the canine region. The buccal wall of the maxillary sinus became thicker anteroposteriorly, except in the region of the second molar, and thinner superoinferiorly. These changes will affect the approach used to osteotomize the lateral sinus wall for oral surgery and for the sinus lift procedure.

“…Previous studies (Levine et al, 2007;Kamburoglu et al 2009;Koivisto et al, 2016;Uppal et al 2017) revealed distances of the MC to both corticals, ranging from 1.7-4.35 mm and 2.6-5.4 mm for lingual and buccal walls, respectively. These measurements are higher than those observed in our population but according to the reports by Huang & Liao (2015) who identified mean values of the MC distance to lingual cortical less than 2.7 mm.…”

SUMMARY:It is critical to know the precise location and configuration of the mandibular canal (MC) to avoid damages in the alveolar inferior nerve during an invasive dental treatment. The aim of this study was to provide anatomic relationships of the mandibular canal in its entire pathway related to cortical walls and dental roots to serve as basic knowledge for dental clinical procedures performed in this area. We analyzed 50 CBCT images assessing the specific location of MC at the retromolar space as related to inferior teeth roots. Data were analyzed by side using descriptive statistics (median: mean [M], standard deviation [SD], 95 % confidence interval: lower endpoint [IC] and upper endpoint [IC']). The MC length and pathway were measured from the mandibular foramen up to the mental foramen. MC was closer from lingual cortical than buccal at the retromolar space as well the distal root of the second molar and the root of the second premolar are closest to MC. A mean length for the MC of 70.8 (±5.3 mm) for the right side and 71 (±5.8 mm) for the left side were observed. In conclusion, it is critical for clinicians to know three-dimensionally the topographic relationships between the inferior teeth roots and the mandibular canal before proceeding to any invasive dental or surgical procedure at this region.

“…However, distortion of 2D panoramic radiography often results in miscalculation of the IMC location (10,11). It is recommended that CBCT, especially cross-sectional imaging offers an excellent image of the morphology of the mandible and the exact location of the IMC, reporting that a defined canal can be detected on the majority of the images (12)(13)(14). IMC is tube-like structure that transverses whole length of mandible from the mandibular foramen in the ramus till the mental foramen in the premolar region ( Figure 1).…”

ÖZET Maksillofasiyal bölgedeki anatomik noktaların CBCT görüntüleriDiş hekimliği radyolojisinde konvansiyonel çekim teknikleri baş ve boyun bölgesinde üç boyutlu kompleks yapıların sadece iki boyutlu görüntülenmesine olanak verir. CBCT, diğer bir ismiyle dental volumetrik tomografi, maksillofasiyal bölgede daha hızlı veri elde edebilmek amacıyla konvansiyonel bilgisayarlı tomografiye (BT) alternatif olarak geliştirilmiştir. CBCT'nin avantajları arasında daha kısa ışınlama süresi, hasta hareketine bağlı olarak oluşan distorsiyonda azalma, multiplanar görüntüleme olanağı ve hastanın maruz kaldığı dozda azalma bulunmaktadır. CBCT klinisyenlerin maksillofasiyal bölgede yer alan anatomik noktaların lokalizasyonun belirlenmesinde ve anatomik yapıların aksiyal, koronal, sagittal düzlemlerde görüntülenmesine olanak sağlar. Bu derlemede maksillofasiyal bölgede yer alan bazı anatomik noktaların CBCT görüntülerinden bahsetmekteyiz. Anahtar sözcükler: Anatomik noktalar, CBCT, maksillofasiyal bölge ABS TRACT CBCT images of anatomic landmarks in maxillofacial regionConventional radiographic techniques in dental radiology allows only 2D images of 3D structures of head and neck region. CBCT is a recent technology, is also named as dental volumetric tomography, which was developed as an alternative to conventional CT using cone beam-shaped X-ray to provide more rapid acquisition of a data set of entire maxillofacial region. CBCT has remarkable advantages such as shorter exposure time, reduced image distortion due to patient movements, decreased patient dose and multiplanar screening. CBCT also allows the clinicians to localize the anatomic structures of the maxillofacial region and these anatomic structures can be visualized in various planes such as axial, coronal and sagittal planes. In this review we mentioned some anatomic structures of the maxillofacial region by using CBCT imaging.
