“…We determined that 17.36% of cases in our study exhibited isthmuses in the apical third region, although limitations in the CBCT technology may mean that the true prevalence rate is even higher as the apical structure is relatively subtle. Fortunately, treatment of this region via apical surgery typically yields favorable clinical outcomes [34]. The treatment of the apical area by apical surgery often achieves ideal clinical results, although surgical success rates are highest in teeth that do not have an isthmus relative to those with a prepared isthmus [35].…”

Background While there is ample research into the anatomy of mandibular molars, little is known regarding isthmuses and middle mesial (MM) canals in Chinese populations. The goal of this study was to determine the prevalence of MM canals and isthmuses in the mesial root of mandibular first molars using Cone-beam Computed Tomography. Methods Cone-beam Computed Tomography images of 357 mature mandibular first molars were retrospectively analyzed. Presence of isthmuses and MM canals, and the length of isthmuses in the mesial root were recorded. Meanwhile, we also recorded possible correlated factors such as demographics, side of mandible, presence of separated distal-lingual roots. Results Of these 357 teeth, 209 showed evidence of either complete or partial communication in the mesial root. Of these, 11(3.1%) exhibited true MM canals while 198(55.5%) exhibited isthmuses. Sex or side of mandible was not correlated with the prevalence of isthmuses (P > 0.05). However, there was a significant association between the presence of a distal-lingual root and the prevalence of such communication (P < 0.001). The average length of isthmuses was 4.3 ± 3.1 mm. Conclusions We detected high rate of isthmuses and low rate of MM canals in mesial roots of mandibular first molars, which is important as such areas should be identified and cleaned during root canal treatment.

Background: While there is ample research into the anatomy of mandibular molars, little is known regarding isthmuses and middle mesial (MM) canals in Chinese populations. The goal of this study was to determine the prevalence of MM canals and isthmuses in the mesial root of mandibular first molars using Cone-beam Computed Tomography.

Results: Of these 357 teeth, 209 showed evidence of either complete or partial communication in the mesial root. Of these, 11(3.08%) exhibited true MM canals while 198(55.46%) exhibited isthmuses. Sex or side of mandible was not correlated with the prevalence of communication (isthmuses or MM canals) (P> 0.05). However, there was a significant association between the presence of a distal-lingual root and the prevalence of such communication (P< 0.05). The average length of isthmuses was 4.3 ± 3.1mm. Conclusions: We detected high rate of isthmuses and low rate of MM canals in mesial roots of mandibular first molars, which is important as such areas should be identified and cleaned during root canal treatment.

“…The rate of post-traumatic complications varies, according to the references, from 7 to 36% (Zuev V. P., 2015; Erokhina I. L., 2016; Eshiev A. M., 2018; Andra A., et al, 2018). Specialized hospitals sometimes fail to offer timely and high-quality care, which leads to repeated surgical interventions and the emerging mandibular defects of disturbed continuity [9,14].…”

— The choice of donor material poses a problem for surgeons handling reconstruction of large combined bone defects or limited maxillofacial bone defects. Restoration methods, applicable in reconstructive microsurgery are based on materials of non-biological origin and musculoskeletal autogenous transplants which have complications and may inhibit the processes of osseointegration. Our study aimed to improve the efficiency of surgical treatment and rehabilitation of patients with mandibular defects using vascularized autograft in combination with macroporous titanium fiber material. The reconstruction of the defective mandible caused by chronic osteomyelitis, trauma, benign tumors was performed in 107 patients either by means of conventional methods (titanium plates, free and vascularized bone autografts), or by a novel engineered bone substitute. Our novel vascularized bone autotransplant combines a macroporous fiber titanium material and spiral bone autochips. For its fabrication we applied digital 3D technologies and methods of rapid prototyping, whereas its vascularization was harvested in iliac crest. Unlike the standard methods of reconstruction, the use of the engineered vascularized implant showed a significant reduction in stages, volume and invasiveness of surgical procedures and an improvement of esthetic and functional outcomes in patients with mandibular defects.
