“…A similar case was reported Kottooret al in which seven separate canals orifices were present but two mesial, distal and palatal canals were joining apically along with one of the mesial canal remained patent till the apex resulting in four obturated canals 20 . In our case five separated obturated root canals can be appreciated.…”

ABSTRACT:SUMMARY: Lack of knowledge regarding basic root canal anatomy and its variations are the main factors responsible for unpredictable treatment outcome. Numerous studies have reported diversity in the root canal morphology of all teeth, and the maxillary 1st molar is no exception. The purpose of this paper is to report a successful nonsurgical endodontic treatment of a maxillary 1 st molar with seven canal orifices. The description of the procedure performed aims to emphasize the need for clinicians to be attentive of variations in root canal anatomy of any teeth that undergoes root canal treatment.

“…The interpretation is known to be limited by complex background patterns such as overlapping roots and anatomic structures like maxillary sinus. As a first step towards improved in vivo imaging, the increasing availability of cone beam computed tomography (CBCT) imaging systems enables volumetric imaging [10,11]. A few recent studies clearly indicate the potential improvement of the diagnosis of periapical lesions by the introduction of CBCT.…”

Purpose: The purpose of this clinical feasibility study was to evaluate the applicability of magnetic resonance imaging (MRI) for the assessment of apical periodontitis in direct comparison with cone beam CT (CBCT). Materials and Methods: 19 consecutive patients (average age 43???13 years) with 34 lesions in total (13 molars, 14 premolars and 7 front teeth) were enrolled in this feasibility study. Periapical lesions were defined as periapical radiolucencies (CBCT) or structural changes in the spongy bone signal (MRI), which were connected with the apical part of a root and with at least twice the width of the periodontal ligament space. The location and dimension of the lesions were compared between MRI and CBCT. Results: While mainly mineralized tissue components such as teeth and bone were visible with CBCT, complimentary information of the soft tissue components was assessable with MRI. The MRI images provided sufficient diagnostic detail for the assessment of the main structures of interest. Heterogeneous contrast was observed within the lesion, with often a clear enhancement close to the apical foramen and the periodontal gap.?No difference for lesion visibility was observed between MRI and CBCT. The lesion dimensions corresponded well, but were slightly but significantly overestimated with MRI. A heterogeneous lesion appearance was observed in several patients. Four patients presented with a well circumscribed hyperintense signal in the vicinity of the apical foramen. Conclusion: The MRI capability of soft tissue characterization may facilitate detailed analysis of periapical lesions. This clinical study confirms the applicability of multi-contrast MRI for the identification of periapical lesions. Key Points: ??MRI can be applied for the identification of periapical lesions without ionizing radiation exposure ??MRI might facilitate more detailed characterization of periapical lesions ??MRI might provide more accurate lesion dimensions as X-ray-based methods Citation Format: ??Geibel MA., Schreiber ES, Bracher AK et?al.
