Tooth autotransplantation has recently become a method of treating certain orthodontic problems. Over a 13-year period 370 premolar transplants were monitored by electrometric pulp sensibility testing and radiographic examination for pulp and periodontal ligament healing as well as root growth. This article describes the surgical technique as well as the(More)
The effect of cryopreservation in liquid nitrogen at -196 degrees C for 1 week was studied by histometric analysis of 60 mature teeth replanted in 10 green Vervet monkeys. The effect of preincubation in enriched tissue culture medium was also investigated. 2 different freezing rates were compared, and the effect of stepwise equilibration of DMSO was studied(More)
The purpose of the present investigation was to determine the long-term prognosis of autotransplanted premolars with respect to tooth survival and pulpal healing. The material consisted of 195 patients aged 7 to 35 years, with a total of 370 autotransplanted premolars with observation period ranged from 1 to 13 years. Teeth transplanted with incomplete and(More)
The purpose of the present investigation was to determine the long-term prognosis of autotransplanted premolars with respect to periodontal healing. The subjects consisted of 195 patients aged 7 to 35 years, with a total of 370 autotransplanted all operated and followed with a standard technique. The observation period ranged from 1 to 13 years. Periodontal(More)
In a retrospective study of a sample of 291 autotransplantations of human teeth carried out by 27 oral surgeons over a period of 25 years, the clinically and radiologically available factors at the time of surgery were analysed with reference to their prognostic relevance. Prognostically relevant factors related to loss of the transplanted teeth were(More)
BACKGROUND An insertion/deletion (I/D) polymorphism of the angiotensin I-converting enzyme (ACE) gene has been postulated to be associated with an increased risk of coronary artery disease (CAD) and myocardial infarction (MI). METHODS AND RESULTS In the present study, the effects of I/D gene polymorphism and of ACE activity on CAD and MI were investigated(More)
BDNF-induced signaling is essential for the development of the central nervous system and critical for plasticity in adults. Mature BDNF signals through TrkB, while its precursor proBDNF employs p75(NTR), resulting in activation of signaling cascades with opposite effects on neuronal survival, growth cone decisions, and synaptic plasticity. Accordingly,(More)
One hundred and eighteen premolars transplanted at a stage with 3/4 to 4/4 root development with a wide open apical foramen were followed with standardized clinical and radiographic techniques for signs of pulpal and periodontal ligament healing and root development. Pulp healing, evaluated first by radiographic presence of pulp canal obliteration, appeared(More)
In orthodontic treatment of certain cases of tooth loss, aplasia, or ectopia, autotransplantation is sometimes a valid treatment alternative and often provides an improved result, compared to conventional orthodontic treatment, if an appropriate donor tooth is available and the anatomic circumstances permit it. However, in some cases autotransplantation is(More)
BACKGROUND Fibrinogen has been demonstrated to be an independent risk factor of cardiovascular disease. The absence of the HaeIII cutting site (H2 allele) of an H1/H2 gene variation in the promoter region of the beta fibrinogen gene was associated with increased levels of fibrinogen. METHODS AND RESULTS In the present study, the effects of the H1/H2 gene(More)
