- The objective of this prospective clinical follow-up was to evaluate the 2-year clinical performance of a nanofilled resin composite in class II restorations. The restorations were made with and without intermediary layer of a nanofilled flowable resin composite studied in an intraindividual comparison. Each participant received at least two, as similar as possible, class II restorations of the nanofilled resin composite. One restoration of each pair (54) was chosen at random to be restored with an intermediary layer with flowable nanofilled resin composite. The other was restored without. The restorations were evaluated with slightly modified US Public Health Services criteria at baseline, 1, and 2 years. Ninety-two restorations, 46 pairs, were evaluated at 2 years. A prediction of the caries risk showed that 22 of the evaluated 48 patients were considered as high-risk patients. Two failures were observed, one in each group, resulting in a 2.2% failure rate. No statistical difference was seen between the restorations restored with and without layer of flowable resin composite. The nanofilled resin composite showed very good surface characteristics and color match, which did not change significantly during the follow-up period. The nanofilled resin composite showed a good clinical performance with a 2.2% failure rate after 2 years. No differences were observed between the restorations with and without the nanofilled flowable resin intermediary layer.

- PURPOSE:Various augmentation procedures involving the maxillary sinus, using bone substitutes or bone, have been used to enhance bone support for dental implants. The aim of this study was to retrospectively evaluate the status of implants in patients who had undergone a maxillary sinus lift and immediate implant placement without the addition of graft material.MATERIALS AND METHODS:Nineteen patients who had required bone augmentation of their maxillary sinus floor were evaluated in this study. After a bone window in the lateral wall of the sinus has been prepared and the Schneiderian membrane had been carefully elevated, dental implants were inserted in the residual bone, creating a membrane elevation. Resorbable collagenous membrane was used to seal the lateral access window of the maxillary sinus after implant placement. Clinical and radiological follow-up was carried out up to 40 months after implant installation.RESULTS:A total of 28 implants in lengths of 10 and 12 mm were placed in a one-stage healing protocol, with an average residual bone height of 5.25 mm (SD = 1.48). All implants remained stable, with a survival rate of 100%. An increase in mean bone height of 4.75 mm (SD = 1.13) was gained. The marginal bone levels relative to the coronal aspect of the implant shoulder exhibited a mean change of 1.01 mm (SD = 0.49) from the baseline. Of the 19 patients, none showed a plaque index or gingival index greater than 2, and 14 patients showed no presence of plaque.CONCLUSION:The findings of the study regarding the immediate placement of implants without the use of bone grafts or other bone substitute materials demonstrate a successful approach for new bone formation around implants in the posterior part of the maxilla, when the preoperative height of the subantral bone is moderate and enough to achieve primary stability.

- The contribution of related donors to the globally rising number of allogeneic haematopoietic stem cell transplantations (HSCT) remains increasingly important, particularly because of the growing use of haploidentical HSCT. Compared with the strict recommendations on the suitability for unrelated donors, criteria for related donors allow for more discretion and vary between centres. In 2015, the donor outcome committee of the Worldwide Network for Blood and Marrow Transplantation (WBMT) proposed consensus recommendations of suitability criteria for paediatric and adult related donors. This Review provides updates and additions to these recommendations from a panel of experts with global representation, including the WBMT, the European Society for Blood and Marrow Transplantation donor outcome committee, the Center for International Blood and Marrow Transplant Research donor health and safety committee, the US National Marrow Donor Program, and the World Marrow Donor Association, after review of the current literature and guidelines. Sections on the suitability of related donors who would not qualify as unrelated donors have been updated. Sections on communicable diseases, clonal haematopoiesis of indeterminate potential, paediatric aspects including psychological issues, and reporting on serious adverse events have been added. The intention of this Review is to support decision making, with the goal of minimising the medical risk to the donor and protecting the recipient from transmissible diseases.
