Current and future trends in periodontal tissue engineering and bone regeneration. Plast Aesthet Res 2021;8:3. http://dx. Abstract Periodontal tissue engineering involves a multidisciplinary approach towards the regeneration of periodontal ligament, cementum and alveolar bone surrounding teeth, whereas bone regeneration specifically applies to ridge reconstruction in preparation for future implant placement, sinus floor augmentation and regeneration of peri-implant osseous defects. Successful periodontal regeneration is based on verifiable cementogenesis on the root surface, oblique insertion of periodontal ligament fibers and formation of new and vital supporting bone. Ultimately, regenerated periodontal and peri-implant support must be able to interface with surrounding host tissues in an integrated manner, withstand biomechanical forces resulting from mastication, and restore normal function and structure. Current regenerative approaches utilized in everyday clinical practice are mainly guided tissue/ bone regeneration-based. Although these approaches have shown positive outcomes for small and medium-sized defects, predictability of clinical outcomes is heavily dependent on the defect morphology and clinical case selection. In many cases, it is still challenging to achieve predictable regenerative outcomes utilizing current approaches. Periodontal tissue engineering and bone regeneration (PTEBR) aims to improve the state of patient care by promoting reconstitution of damaged and lost tissues through the use of growth factors and signaling molecules, scaffolds, cells and gene therapy. The present narrative review discusses key advancements in PTEBR including current and future trends in preclinical and clinical research, as well as the potential for clinical translatability.

Different studies suggest that incidence of hypoxemia and incidence of arterial oxygen desaturation are reduced by early intervention via capnography monitoring. The aim of this article was to discuss the importance of implementing capnography monitoring during procedural sedations performed in a dental setting and determine whether additional capnographic monitoring reduces the incidence of arterial oxygen desaturation and the overall complications rate. Materials and methods Two independent reviewers conducted electronic (PubMed and EMBASE) and manual searches up to February 2020. Randomized clinical trials (RCTs), including both patients under procedural sedation monitored by capnography and oximetry, and reporting the incidence of hypoxemia or episodes of oxygen desaturation were included. Risk ratio was used to compare the outcomes (i.e., the incidence of hypoxemia, the episodes of oxygen desaturation, the detection of apnea, the reduction of events of bradycardia, and hypotension) between patients monitored by capnography and standard approach. Results Fourteen randomized clinical trials fulfilling the inclusion criteria were selected. The analysis revealed that capnography monitoring group showed the lower incidence of hypoxemia (RR 0.76, 95%CI 0.70 to 0.83, p < 0.001) and the episodes of oxygen desaturation (RR 0.79, 95%CI 0.71 to 0.87, p < 0.001) compared with the oximetry monitoring group. Apnea was detected in capnography monitoring earlier than standard monitoring (RR 2.60, 95%CI 2.30 to 2.93, p < 0.001). No significant difference was found between capnography and standard monitoring groups in terms of reduction of events of bradycardia (RR 1.17, 95%CI 0.91 to 1.50, p = 0.225) and hypotension (RR 0.96, 95%CI 0.76 to 1.21, p = 0.746). Conclusion Capnography monitoring reduced incidence of hypoxemia during procedural sedations. Within the limitations of this review, we suggest that the application of capnography during procedural sedation would decrease the frequency of oxygen desaturation events and incidence of hypoxemia. Clinical relevance Training and instructing dental providers on using capnography monitoring would help in reducing adverse events during intravenous sedation.

It is a reference that clinicians can use when deciding to save or extract a non-vital tooth. Several factors that are commonly encountered in daily practice are considered in this proposed decision-making process and they are history of endodontic treatment, status of previous endodontic treatment, presence/absence of active infection, size of apical radiolucency, periodontal status and patient´s preference.
