Preserving the Neurovascular Bundle in Targeted Endodontic Microsurgery (TEMS): A Case Series
Endodontic microsurgery encompasses the use of microscopy, specialized instruments and advanced imaging with cone beam computer tomography (CBCT). This treatment modality results in high clinical success rates and facilitates the enucleation of osteolytic lesions, resection of apical root canal complexities harboring persistent bacterial biofilms, and evaluation of possible root defects and fractures. However, there is the risk of injury to important anatomical structures, particularly when treating posterior teeth. (Source: Journal of Endodontics)

Selective Retreatment and Sinus Lift: An Alternative Approach to Surgically Manage the Palatal Roots of Maxillary Molars.
Endodontic microsurgery on the palatal root of maxillary molars presents a clinical challenge due to the root position and approximation from the maxillary sinus floor. Attempting a buccal or a palatal approach to address the root is associated with limited accessibility and visibility, as well as the risk of injury to the maxillary sinus membrane and/or the greater palatine nerves and vessels. If all the maxillary molar roots require surgical intervention, two flaps may even be needed, which can make the procedure technically more difficult and lengthier. (Source: Journal of Endodontics)

Combined Root Canal Therapies in Multirooted Teeth with Pulpal Disease
The types of pulpal disease found in multirooted teeth may vary from one root canal to the next. Current endodontic treatment strategies allow for the options such as regenerative endodontics, vital pulp therapy, or conventional root canal treatment depending on the disease status of the pulp in a specific root canal. A combination of procedures was employed in the three teeth in for this case series based on the assumed pulpal status in each canal. The follow-up ranged from 24 to 27 months and in each case the healing response was satisfactory. (Source: Journal of Endodontics)

Regeneration of Pulp-dentin Complex in a Tooth with Symptomatic Irreversible Pulpits and Open Apex Using Regenerative Endodontic Procedures
Regenerative endodontic procedures are undertaken on permanent teeth with necrotic pulps and open apices in an attempt to resolve symptoms, to allow the continued development of the root(s), and to re-establish vitality. Available histologic analysis of these teeth has, in the majority of studies, shown that true regeneration of the pulp-dentin complex is not achieved. A recent investigation using an animal model outlined a procedure whereby pulpal amputation a few millimeters short of the apex followed by evoked bleeding allowed the complete regeneration of the normal pulp-dentin complex in immature vital teeth of ferrets...

Fabrication of tapered fluidic microchannels conducive to angiogenic sprouting within GelMA hydrogels
Transplantation of stem cells/tissue constructs into root canal space is a promising strategy for regenerating the lost pulp tissue. However, the root canal system, which is cone-shaped with a taper from the larger coronal end to the smaller apical end, limits the vascular supply and therefore, the regenerative capacity. The current study aimed to fabricate built-in microchannels with different tapers to explore various approaches to endothelialize these microchannels. (Source: Journal of Endodontics)

Guided endodontics: use of a sleeveless guide system on an upper premolar with pulp canal obliteration and apical periodontitis.
Guided endodontics has been used for the treatment of anterior teeth, with a successful outcome. This approach is not only limited to anterior teeth as it can also be used for the treatment of premolars and molars. However, in such cases, space may be a limitation since a long bur has to be used in addition to the guide been placed on top of the teeth. The aim of this case report is to present a novel guided endodontics technique using a sleeveless 3D printed guide. This design can reduce vertical space, allowing an open view of the tooth and irrigation during drilling. (Source: Journal of Endodontics)
