The increase in oral rehabilitation by means of dental implants has required an evolution of the related managing protocols and correct updating of the skills of dental professionals. Postsurgical management of the clinical case is aimed to stabilize the obtained results and preserve them from adverse conditions: a healthy implant prosthesis is maintained thanks to the huge number of consolidated protocols of oral hygiene. This practice plays a decisive role in the prevention of perimplant pathologies, forming a strong basis to ensure long implant life and avoid unnecessary and painful new surgical procedures...

The common use of dental implants in the daily practice led to a profound change in the available treatment strategies. The option of replacing a diagnosed doubtful tooth with an implant has become widely accepted and often used. The prognosis systems in use today are based on the three major disciplines: endodontics, periodontics and prosthodontics. Combining these three may impair and bias the decision making process and increase the tendency to base it on subjective clinical experience and personal preference...

Integrins are the major receptors within the extracellular matrix (ECM) that mediate several functions connected with cell life and metabolism, such as cell adhesion, migration, cytoskeletal organization, proliferation, survival, and differentiation. A vascular endothelial growth factor (VEGF) is one of the most important angiogenic factors. It has been suggested that the expression of this gene may play crucial physiological roles in reproductive organs. All investigated endometrial tissues were isolated on day 10-12 after mating...

Studies of early placental development in humans are difficult because of limitations on experimental material availability from the perimplantation period. We used a coculture system to determine the effects of various effector cell types on trophoblast differentiation. Enhanced green fluorescent protein (EGFP)-expressing H1 human embryonic stem cells were used in co-suspension with human term placental fibroblasts (TPFs) and dermal fibroblasts (CI2F) to form combination embryoid bodies (EBs), with the goal of recapitulating placental morphogenesis through incorporation of placental mesenchymal cells...

BACKGROUND: One of the key factors for the long-term success of oral implants is the maintenance of healthy tissues around them. Bacterial plaque accumulation induces inflammatory changes in the soft tissues surrounding oral implants and it may lead to their progressive destruction (perimplantitis) and ultimately to implant failure. Different treatment strategies for perimplantitis have been suggested, however it is unclear which are the most effective. OBJECTIVES: To identify the most effective interventions for treating perimplantitis around osseointegrated dental implants...

Integrin are adhesion molecules involved in uterine-conceptus interactions during the perimplantation period. In this study, the expression of alphaV and beta3 integrin subunits in endometrium during implantation in pigs was investigated. The immunohistochemical location was performed on paraformaldehyde-fixed, paraffin-embedded tissue sections, and the mRNA expression of alphaV was detected in endometrium. In addition, serum levels of estradiol, progesterone, follicle-stimulating hormone, and luteinizing hormone were measured on Days 0, 12, 18, and 25 of pregnancy...

We tested the hypothesis of no difference in implant failures between various dental implant types. We searched for all randomised clinical trials comparing different implant types/systems with a follow up of at least one year on four databases. Screening of eligible trials, quality assessment and data extraction were conducted in duplicate. Thirty-one trials were identified. Twelve trials, reporting results of 512 patients, were included. No significant differences were observed for implant failures. There were minor statistically significant differences for peri-implant bone level changes...

A series of experiments were conducted to determine whether bovine blastocysts would develop beyond the blastocyst stage in the ovine uterine environment. In Experiment 1, in vitro matured, fertilized and cultured (IVM/IVF/IVC) expanded bovine blastocysts were transferred into uteri of ewes on Day 7 or 9 of the estrous cycle and collected on Day 14 or 15 to determine if the bovine blastocysts would elongate and form an embryonic disk. Springtime trials with ewes that were synchronized with a medroxyprogesterone acetate (MAP) sponge resulted in a 78% blastocyst recovery rate, and 68% of the recovered spherical or elongated embryos had embryonic disks...

Both in human and in rat, two types of placenta are present: the yolk sac (YS) and the chorioallantoic placenta. Histiotrophy, alpha-fetoprotein synthesis and blood cell formation occur in YS of both species. Besides, the midgut, primordial germ cells and possibly immunological structures originate from the YS tissue. The specialised cells of the chorioallantoic placenta attach the embryo to the uterus and form the vascular connections necessary for the nutrient transport. The placenta redirects maternal endocrine, immune and metabolic functions to conceptus advantage...

The pattern of sperm centrosomal (centriolar) inheritance, centrosomal replication and perpetuation during mitosis of the human embryo is reviewed with a series of electron micrographs. Embryonic cleavage involves repeated mitoses, a convenient sequence to study centriolar behaviour during cell division. After the paternal inheritance of centrioles in the human was reported (Sathananthan et al., 1991a), there has been an upsurge of centrosomal research in mammals, which largely follow the human pattern. The human egg has an inactive non-functional centrosome...

Changes in the organization and composition of apical cell surface glycoconjugates accompany the transition of luminal epithelial cells from the prereceptive state of the uterus in many species. In spite of the biological and clinical significance of this process, few molecular markers have arisen as useful predictors of uterine receptivity. Recent studies in mice demonstrate that the transmembrane mucin glycoprotein, Muc-1, is abundantly expressed at the apical surface of luminal epithelia under most conditions and is invariably reduced in receptive uteri...

During periimplantation, the estrogen biosynthetic capability of the porcine conceptus is transient, coincident with morphological development (trophoblast elongation), and temporally associated with maximal uterine release of insulin-like growth factor-I (IGF-I) into the luminal fluid. We investigated the possible linkages of conceptus steroidogenesis and IGF-I by characterizing the developmental expression of the pig conceptus cytochrome P450 aromatase (P450arom) and cytochrome P450 17 alpha-hydroxylase (P45017 alpha) genes during periimplantation (days 8, 10, 12, 15, and 18) and the potential regulation by IGF-I of conceptus P450arom messenger RNA (mRNA) content...

The mouse blastocyst undergoes a program of protein secretion during the perimplantation period including the initial production of placental lactogen-I (mPL-I) on day 6 of pregnancy. Although blastocysts collected on day 5 also produce mPL-I when cultured to form outgrowths on plastic dishes, it was not known if embryos have an intrinsic ability to produce mPL-I during culture in vitro, or if a specific uterine influence is necessary. Earlier experiments also suggested that attachment of the trophoblast to a stable surface may be a prerequisite for synthesis of mPL-I...

Thiotepa-induced perimplantation mortality in mice was analysed cytologically. The contribution of induced chromosomal aberrations to preimplantation embryonic death was studied. Under the influence of 1.25 mg/kg of thiotepa on late spermatids the stop of cleavage division was found at 2--16 cell stage in 27% of the cases and at 17--22 cell stage in 11.9% (totally in 38.9%) as compared to 6% in the controls. The cytogenetic analysis of embryos consisting of 2--16 cells revealed gross structural chromosomal aberrations in 75% metaphases suitable for analysis...
