“…The distance from the first molar roots was similar to that reported in some studies (Bornstein et al, 2011;Bürklein et al); however, it was significantly different from the findings of Koivisto et al (2011) (2.3mm) and Sato et al (1 mm). Also, the distance from second premolar to MC reported by Koivisto et al (2016) (2.6mm) was lower than that of the values identified in this study (4.1-3.9 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.

“…In maxillary molars, it is particularly helpful in assessing the palatal roots [39]. The distance between the cortical plate and the palatal root apex can be measured, and the proximity to maxillary sinus or nasal floor can be assessed ( Figure 5D, 5E) [38]. The presence of isthmuses can be identified [40].…”

“…Use of CBCT has been recommended for endodontic surgery treatment planning since it enables the assessment of the lesion in three dimensional plane in terms of its location, extent, position of the roots within the bone, proximity to anatomic vital structures such as inferior alveolar nerve, mental foramen, maxillary sinus and nasal cavity. 53 It also allows better visualisation of the extruded endodontic material and its proximity to the inferior alveolar nerve and mental foramen than 2D radiography. 54 Periapical radiographs are found to be less sensitive in detecting lesions associated with the upper molar teeth since the root apices are in very close proximity to the floor of the maxillary sinus (Anatomic noise).…”

BACKGROUNDRadiographic imaging is a preliminary and essential step in the diagnosis, treatment planning and followup of all the cases in endodontics. The interpretation of an image can be influenced by several confounding factors including the regional anatomy a nd superimposition of both teeth and the surrounding dentoalveolar structures. Due to the complexity of the maxillofacial skeleton, conventional two dimensional (2-D) radiographic images fail to provide accurate information of the particular region of interest. Superimposition of the images, seen in planar periapical radiography, reveal only limited information about a three dimensional (3-D) object. The structures so visualised are also subject to geometric distortion. Hence, recent research has highlighted the need for 3-D imaging modality to overcome the potential drawbacks of conventional radiography. Medical Computed tomography (CT) was one of the earliest three dimensional imaging systems. It has been used in the field of endodontics over the past decade but with limited success. This can be ascribed to high radiation exposure, lengthy scan time and cost factor. The next new phase in imaging modalities came with the advent of cone beam computed tomography (CBCT). Contemporary endodontics emphasise on the significance of CBCT, since it limits the radiation exposure and rapidly provides 3D reconstructed images which have been proven to be accurate in all aspects. This paper reviews the importance of three dimensional CBCT technology over conventional two dimensional imaging system along with its potential drawbacks. BACKGROUND Diagnostic imaging is considered as an important adjunct in clinical assessment of the patient. Since time immemorial, radiology has played a critical role in dentistry and now with expanding array of different imaging modalities, it has become an indispensable tool in endodontic assessment as well. The first intraoral radiograph to be used in dentistry was reported by Sir C Edmond Kells. 1 Thereafter, field of radiology has seen several changes. With improvements in the film technology and reduced exposure times, gradually film based system gave way to advanced sensor based digital systems. Solid state sensors like charge coupled device (CCD), complementary metal oxide semiconductor (CMOS) and photostimulable phosphor plates (PSP) largely replaced the film based conventional imaging. 2, 3, 4 Digital systems also provided opportunities for image processing and modification (colour, brightness, contrast) which further assisted the diagnostic process. But the images were still a two dimensional representation of three dimensional anatomy and the need for cross sectional information was still unmet.
