“…The graphic presentation of ovals, representing 95% CI of root canal diameters on photography of the dental arch enhance visualization of appropriately positioned and sized access [Figure 1]. It should be emphasized that this could only serve as a guideline, as there are numerous cases demonstrating anatomic variations not only in complex teeth as molars, but also in incisors,[12] canines,[13] and premolars[1415] which are usually considered as teeth with less complicated anatomy. Exact size and location, especially in complex cases, should therefore be always evaluated from periapical radiographs or cone beam computed tomography scan.…”

Background:Ideal access cavity assures unobstructed straight-line access to the apical third of the root canal and preserves tooth structure.Aim:The aim of the study was to determine the location and dimensions of access cavity with straight-line access in incisors, canines, and premolars and to evaluate the largest diameter of their root canals in the mesiodistal and vestibulooral direction.Materials and Methods:Twenty extracted teeth of each group were randomly selected and digitally radiographed from the mesiodistal and vestibulooral direction. Position of the straight-line access midline in relation to anatomical landmarks (incisal edges, fissures, and cusps) was recorded. The largest diameters in mesiodistal and vestibulooral direction were measured. Relative frequencies of access position and mean and standard deviation of both diameters were calculated.Results:For the anterior teeth, the predominant location of straight-line access was from incisal edge, except for maxillary central incisors, where location was equally distributed between incisal edge and oral surface. In mandibular premolars, the straight-line access was positioned vestibular from central fissure. In mesiodistal direction, the largest diameter was found for maxillary central incisors and canines (1.54 mm), while the smallest diameter was found for mandibular incisors (0.64 mm). In vestibulooral direction, the largest diameter was found for maxillary first premolar (5.28 mm), while the smallest diameter was found for maxillary lateral incisor (1.39 mm).Conclusions:Knowledge of location and size of access cavity facilitates achieving balance between straight-line access to the apical third of the root canal and preservation of tooth structure.

“…Managing the S-shaped curvature MB2 canal is also a major challenge for clinicians. Besides the application of double flare technique [18], the Ni-Ti rotary files by Dentsply, Pathfiles which prove to be flexible, should be applied to create a smooth glidepath in curved canals before the shaping phase with rotary files. Compared to previous manual stainless steel files, conducting canal preparation with Pathfiles considerably minimize canal defects at curvature portion [19] as well as periapical infections of the root [20].…”

BACKGROUND: Anatomic variations in palatal canal morphology in maxillary first molars (MFMs) are relatively rare occurrences. Therefore, omission is common unless clinicians recognize their presence. CASE REPORT: The aim of this report is to point out new signs that can be viewed as indicators of the existence of additional canals in the palatal root (PR) in this upper first molar endodontic retreatment case. Moreover, the role of preoperative cone-beam computed tomography (CBCT) in both discovering and determining the location of those additional canals will also be discussed. CONCLUSION: Besides formerly discussed signs that indicate the existence of this canal, clinicians should also pay attention to other signals on periapical radiograph, including the aberrant divergence of a palatal canal at apical third and an unusual lesion occurring laterally in the periapical area of palatal root.

“…1,7,9,15,12 Cone beam computed tomography (CBCT) is another accurate option for consideration as it allows a threedimensional view of teeth with complex root canal variations. [21][22][23][24] In this case the diagnosis, location, negotiation, and obturation of the patient's maxillary second premolar was completed without the need for radiographic images from multiple angles since all the canals and roots were clearly visible on the initial radiographic image (Figure 1).…”

“…Restoration of the endodontically treated tooth remains a challenge. 21,22 A successful endodontic procedure requires a final restoration to restore the form, function, and aesthetics of the tooth and to improve the long term prognosis 23 An endodontically treated maxillary second premolar is susceptible to fracture because of cusp deflection. 24 It is therefore essential that oral health practitioners choose a suitable restorative option for this tooth to improve the long term prognosis.…”
