The aim of this study was to compare the prognosis of separated and non-separated tooth autotransplantation of the upper first and second molars with complete root formation undertaken at dental clinics. The participating dentists were requested to provide information on transplantations they had undertaken from 1 January 1990 to 31 December 2010. Data on a total of 708 teeth from 637 patients were collected. This study analysed 35 separated teeth and 22 non-separated teeth of 47 participants ranging from 27 to 76 years of age (mean age: 55·0 years) after data screening and elimination. The cumulative post-transplantation survival rate at 10 years was 77·1% for separated teeth and 63·6% for non-separated teeth as calculated with the Kaplan- Meier method. There were no significant differences between separated teeth and non-separated teeth in a log rank test ( P = 0·687). Separated-tooth autotransplantation can help fill narrow recipient sites and increase occlusal supporting zones, but the clinical success rate was only 48·6%. Although transplantation of teeth with complete root formation has limited prognosis, transplantation of upper first and second molars, whether separated or non-separated, is a viable option to replace missing teeth.

Abstract: Objective: Laparoscopic living donor nephrectomy (LLDN) has become the standard procedure for renal transplantation. This technique is considered less invasive for the donor, allowing lower postoperative analgesic requirements and a faster return to daily activities. In Japan, 1123 renal transplantation were performed in 2009. And, almost 83% were living related procedures. The aim of this study was a retrospective assessment of the safety and outcomes of LLDN on renal transplantations. Material and methods: We retrospectively analyzed the intraoperative data and surgical complications for 21 patients who underwent retroperitoneoscopic living donor nephrectomy between June 2009 and March 2011. Results: LLDN was successfully completed in all patients, without conversion to open surgery. Mean operative time was 243.5 ± 46.0 minutes with an average blood loss of 46.0 ± 46.1 mL. Warm ischemic time was 2.1 ± 0.62 minutes. Hospital stay was 11.1 ± 2.7 days. There were no major donor complications. One patient presented a wound infection responding to conservative treatment. Conclusions: LLDN is a safe effective procedure. The vascular stapler is useful to manage the renal vessels. [Copyright &y& Elsevier]
