Studying the workforce in the professional qualification context: the US experience
Authors: Perkhun L. Р.
Published: October 2018

The article examines the American experience of studying the workforce in the professional context. Statistical analysis of employment by occupation will reveal both trends in change in typical tasks of individual workplaces and objective knowledge, skills and competencies of workers in different sectors of the economy and the risks of their inconsistency with formal qualifications.

The results of statistical analysis of employment by occupation can be used to elaborate and adjust strategies for the development of the economy of the state or its individual sectors (for the development of the economy at federal, state and industry level), educational institutions, to choose a future profession, to determine career development tools, and to choose the business location

Comparative analysis of the contents of the normative documents on the classification of professions of the United States and Ukraine showed the need to develop a new version of the normative document for the classification of occupations in the professional context on the basis of the existing Classifier of professions and the Directory of Qualification Characteristics.

The results of the statistical study of the workforce in terms of professions are displayed on the official BLS. However, more interesting and useful for a common user is a specially created OnLine 0*NET service. On request for the chosen profession, the complete information (“summary”) is provided: the title and the code of the profession, the nomenclature of professional tasks, the sample of reported job titles, the nomenclature of typical tasks of the activity, the necessary knowledge, professional skills, technology skills, abilities; work activities; the description of the work context, the required level of education; educational institutions and certification centers where you can get training or further training in the chosen profession; necessary personal qualities; related occupations; wages & employment trends (for each State and each type of industries); job openings on the web. There is no similar service in Ukraine.

In order to create an effective system for studying the workforce in Ukraine professionally and to use convenient services for the results obtained, the efforts of scientists, practitioners and IT specialists need to be combined.

Authors: Rynhach N. О. , Ogay M. Yu. , Havrylova V. V.
Published: October 2018

The article is devoted to the analysis of the choice of ways to find sources of information about a healthy lifestyle and prevention and treatment of cardiovascular diseases (CVD) by people of working age. The aim is to identify and characterize the preferences of residents of the Dnipropetrovsk region regarding the selection of channels for obtaining medical information, the degree of trust in them, as well as the need for additional sources based on the results of a two-stage sociological study

The method of in-depth interviews (N 20) and the method of personalized formal interviews (N 2000) have been used. The survey among the representative sample of the population of working age was carried out according to a specially developed methodology of qualitative and quantitative research stages and data collection tools. The research was conducted in 2017 on request of the Dnipropetrovsk Regional State Administration with the financial support of the World Bank.

It is shown that the most popular source of knowledge on the prevention and treatment of cardiovascular diseases and healthy lifestyle are medical professionals: almost half of the polled (46.0%) reported receiving the necessary information from them, mainly from a family doctor or a district doctor (32.8%); twice less than cardiologists (16.0%); sometimes from doctors of other specialization and other medical workers (10.5%). The criterion for selecting a source is trust in him, while the overwhelming majority entrusts it to medical workers.

The expediency of developing a special Internet resource devoted to the issues of preserving and strengthening the health of the population, reducing the risk factors, prevention, diagnosis and treatment of CVD and other diseases has been proved.

Life path and scientific work by William Petty
Authors: Halytska Е. V. , Primierova О. K. , Siemikolenova S. V.
Published: October 2018

The article is devoted to the scientific and practical activities of the prominent representative of the school of political arithmetic W. Petty. He was a well-known English economist, physician, inventor of copying equipment, doctor of physics, professor of astronomy, founder of English classical political economy, statesman, one of the founders of the Royal Society of London.

In the article the biography of W. Petty is outlined and his role in the formation of scientific statistics is considered. The main works of the scientist such as: “Political arithmetic”, “A Treatise of Taxes and Contributions”, “Verbum Sapienti posthum”, “Political anatomy of Ireland” are analyzed. The views of the scientist on a wide range of socio-economic problems of the time and directions of their solution are considered

Petty’s contribution to the development of methodological foundations of statistical science is determined. The article emphasizes the historic merit of the scientist in creating the basis of the statistical- economic method of research. The focus was made on W Petty’s application of the methods of collecting, processing, systematization and generalization of statistical information. W Petty first calculated the magnitude of the national wealth of England and Wales and made calculations of the national income, as well as differentiated these concepts and paid attention not only to the monetary form, but also material. In essence, from these calculations we can speak about the emergence of the foundations of the modern system of macroeconomic national accounting.

It was also a great achievement of W Petty that he identified his main task of studying the laws of social phenomena. He was the first to raise the issue of the necessity of establishing a state statistical service and outline outlined its main activities. His achievements of the scientist concerning forecasting and comparative characteristics of the population of large cities of Europe are also considered.

The article reflects the thoughts and statements of the descendants of W Petty, well-known researchers in the history of statistics, who highly appreciated the role and contribution of the scientist in the formation of statistical science.
The Number of Nephrons in the Kidney: A Relevant Question Implicated with Arterial Hypertension
Authors: Mandarim-de-Lacerda Carlos , Aguila Marcia , Younes-Ibrahim Mauricio
Published: October 2018

Stereological methods are used to obtain quantitative information about the three-di- mensional structures based on observations on cutting planes or, to a limited degree, projections. Stereological methods, which are used in biological research, and especially in the study of normal and pathological kidney, are powerful tools for the study of the kidney. The study of kidney development, with emphasis on subtypes of clusters found in this period of intrauterine life, has relevance to assess renal maturity and the consequences of changes in the normal process. Several studies have shown that the total number of nephrons varies widely in normal human kidneys. An association between the small number of nephrons and subsequent development of hypertension in adulthood has increasingly been accepted. There is sufficient experimental and clinical evidence to conclude that blood pressure is associated with the number of nephrons, although this concept is not unanimous in the literature.

In conclusion, variations of the osteotomy in the anterior area of the mandible are used according to individual requirements of each case, and can be performed with a low morbidity.
Embryonic Annexes
Authors: Rojas Mariana , Rodríguez Ángel
Published: October 2018

In vertebrates, depending on the environment in which an embryo develops, different types of extraembryonic membranes are formed. In placental mammals the following extraembryonic membranes are formed: amnion, yolk sac, allantois, chorion and placenta. Extraembryonic membranes perform functions vital to the embryo. The amnion protects the embryo from drying, the mechanical trauma, temperature changes and adhesions which can distort it. The yolk sac is present in all vertebrates. In mammals allows the formation of the first blood vessels and the first blood, home to the primordial germ cells for some time; however, in fish and birds these have nutritional importance. In birds and mammals such as cattle, sheep and pig the allantois receives urinary wastes; this structure also contributes part of the bladder and at the time of birth becomes the suspensory ligament, urachus. The chorion form chorionic villus, which can produce hormones such as chorionic gonadotropin and human placental lactogen. A portion of the chorionic sac helps form the placenta.

Role of Ubiquitin-proteasome system in Espematogenesis
Authors: Zapata Héctor , Morales Patricio , Jara Marco
Published: October 2018

Spermatogenesis is a series of events that constitute programmed cell differentiation, with dramatic changes in morphology, biochemistry and gene expression which are regulated by temporal and especially endocrine, paracrine and autocrine mechanisms. During the various stages of spermatogenesis and particularly during the differentiation of spermatids, there is massive degradation of cytosolic proteins, nuclear and membrane due to the elimination of much of the cytoplasm which has round spermatid. This protein degradation occurs within the seminiferous epithelium and is mediated by cellular systems described for this purpose. The proteasome is a multienzyme complex responsible for degrading the majority of nuclear and cytosolic proteins, after they are marked for destruction by covalent attachment of ubiquitin molecules. This selective destruction of cellular proteins is a key mechanism in the process of spermatogenesis. This article discusses the basics of male gonadal physiological process and the current understanding of the role of the ubiquitin proteasome system in the functional maintenance of spermatogenesis are reviewed.

Authors: Reyes María , Bustos-Obregón Eduardo , Rojas Mariana
Published: October 2018

This paper deals with the efficiency of in vivo gene transfer to the mouse cauda epididymis and its relation to androgens. Previous experiments in the female reproductive tract have indicated that the efficiency of transfection is related to the hormonal stage of the animal, nevertheless no analysis have been done in the male tract. We used in vivo gene transfer to the mouse cauda epididymis employing a gene construction that expresses the Green Fluorescent Protein (GFP). Untreated and Testosterone treated males were employed. Testosterone injections (5 μg/g weight) were done from 2 days before the gene transfer, and treatment continued each day during a total period of 15 days. Fluorescence microscopy observations showed the expression of GFP in the cytoplasm of the principal cells in the epididymal tubules. The application of the QWin Program that measures the percentage of fluorescent areas showed that they are increased in the epididymis of treated males. This increase was particularly observed two days after gene injections (from 32.24 % in untreated animals to 47.62 % in testosterone treated males) and after seven days (from 29.98 % to 43.05 %). The possibility to improve transfection efficiency would increase the knowledge on epididymal physiology and would permit to modify the fertilizing capacity in mammals.

Authors: Salinas Paulo
Published: October 2018

Flow cytometry is a useful technology in the sexed sperm, which measures and analyzes simultaneously, multiple physical characteristics of the cell, as they flow in a stream flow, through a light beam. The measured properties are the size of a particle, relative internal granularity, relative complexity and relative fluorescence intensity. Currently, hundreds of calves have been gestated through artificial insemination with sexed sperm in animal production. Since 1992, flow cytometry has been used, a technique that allows spermatozoa X and Y differentiation by DNA content. There is no other practical technique for sperm sexing to keep sperm functionality. The objectives of this review are to explain: (1) why the sperm containing the X or Y chromosome are phenotypically similar, but differ among themselves, (2) the principles and procedures used for sexing sperm by flow cytometry and sorting ( 3) accuracy, speed and efficiency of current procedure sperm sexing, (4) sperm damage occurred during sperm sexing and consequently the effects on fertility.

The dermato parasitosis produced by the Sarcoptes scabiei mite hominis variety, has a population distribution related to overcrowding, poor sanitation, poverty and geo-climatic characteristics. Transmission occurs directly through skin or fomites. In the border town of Liquiñe in the Region de los Rios, Chile, a substantial amount of the population is subject to the above characteristics, with difficult access to digital communication and medical referrals. The incidence of scabies is modified through educational interventions, and local sanitation, as well as early diagnosis and timely treatment thus achieving a substantial change in prevalence. A case report is presented. Female patient, 33 years old presents with excoriated crusted lesions, with papules and pustules following two years of development, initial symptomatic management diagnosis of psoriasis and dermatitis, showed no improvement of the lesions. At the same time the 4 year old daughter of the patient presented with primary lesions similar to baseline characteristics. The child ́s lesions presented as vesicles in interdigital space, wrists, periumbilical region and mite grooves compatible with scabies. Permethrin 5% topical treatment was prescribed for the whole family, based on the recommendations of the MINSAL guide management is initiated. At 2 months of treatment therapy onset, complete recovery was achieved following two years of evolution of signs and symptoms. This case review aims to reinforce the ideas of early diagnosis, in both probable index case and contact, and continuing education in the community. Effective and timely treatment, in conjunction with the socio- cultural reality of each community, taking into account risk factors, such as seeking medical treatment and abandoning therapy. Furthermore, it is also intended to promote institutional networks for treatment dissemination, counseling by specialists and updated information for each dermatological presentation for the general medicine physician.

Vitamin D Metabolism: Role in the Genesis of Diseases
Authors: Schulz Mabel
Published: October 2018

Vitamin D has traditionally been associated with bone metabolism, however it exerts different functions in various tissues of the body that possess the vitamin D (VCR) receptor and they are susceptible to its effect. Decreased vitamin D has also been associated with "nonclassical" diseases such as hypertension, metabolic syndrome, insulin resistance, diabetes, development of some cancers, lung disorders, autoimmunity and infertility, among others. Maternal vitamin D deficiency has been associated in the genesis of postnatal diseases. Further, many of these pathologies are produced by molecular alterations, mainly related to metabolism and receptor polymorphisms VCR. Vitamin D is considered a hormone, can be synthesized in the skin from 7-dehydrocholesterol by ultraviolet radiation B. The metabolism is complex and involves the interaction of several factors in its incorporation and final formation of calcitriol, the active form. To produce its effect requires activation of VDR receptor on the target cell, which activates specific gene sequences with different functions, through DNA promoter sequences in identified vitamin D response elements (VDRE). Many tissues have the VDR receptor and enzymes necessary for metabolism, so the spectrum of vitamin D action is very broad in the variety of pathologies produced. This review of vitamin D focuses primarily on the molecular aspects of its metabolism and its role in the genesis of "nonclassical", diseases, product of its reduction or alteration of metabolic diseases.

Published: October 2018

Treatment of mandibular fractures and their sequelae are difficult to resolve in the maxillofacial surgery field, their components cause that reduction must not only be anatomic, but functional as well. The aim of this article is to present a review about actual knowledge in mandibular fracture treatment and report a case of mandibular trauma. The treatment of these fractures has been changing through the years; the new technologies achieve better reduction with the osteosynthesis systems, which results in reduced approaches and lesser morbidity. Presently, titanium plates systems like mini-plates, reconstruction plates or blocking plates offer excellent results in high energy traumas through anatomic and stable reductions. The technology of 3D reconstruction systems and intra-operatory CT accomplishes better results in trauma treatment.

Published: October 2018

The irrigation of the palm is provided by arterial arches (shallow and deep) that are made more frequently by the ulnar or radial arteries described as setting a classic pattern. Anatomical variations are described in shaping both arches, most often in the superficial palmar arch; may be the same complete or incomplete. The objective of this work is the anatomical description of the palmar arches, their different patterns and variations in conformation, and their clinical and surgical implications. A descriptive, observational and morphometric study of the arteries involved in the formation of the palmar arches was done in the Faculty of Medicine, University of Buenos Aires. One hundred1(00) cadaveric preparations fixed in formalin solution, of the Third Chair of Anatomy were used. A retrospective analysis of cases with lesions / s artery / main / s that make the palmar arches in the Emergency Hospital of Moron, between 2015-2016 s was also carried out. Most frequently the radial artery forms the deep palmar arch with the deep palmar branch of the ulnar artery. Superficial palmar arch is the most variable. It was complete in 56 % and the most common presentation (83 %) is one that is formed by the anastomosis of the ulnar artery and the superficial palmar branch of the radial artery. The rest of the anastomosis are between ulnar artery and median artery (9%), between deep branch of radial artery and ulnar artery (5 %); triple anastomosis between ulnar artery, median artery and superficial palmar branch of the radial artery (2 %), and anastomosis between the median artery and superficial palmar branch of the radial artery without participation of the ulnar artery (1 %). The rest of the sample (44 %) can be termed as incomplete. The B1a and B1b subtypes were the most found. Two cases, one entire section of the radial artery at the wrist and the other with complete section of ulnar artery with involvement of the ulnar nerve are described. It is essential to a proper understanding of the palmar arches for a suitable surgical approach to hand. The importance of the presence or absence, as well as different variations of palmar arterial arch lies in its clinical application as surgical starting point in the treatment of trauma and other diseases in which there is engagement of arteries.

Published: October 2018

Osteoarthritis is a type of articular origin Temporomandibular disorders, being one of the most common degenerative processes affecting the temporomandibular joint. It is characterized by remodeling of the underlying subchondral bone, deterioration and abrasion of articular tissue. Intra-arti- cular injections of hyaluronic acid are considered beneficial for treatment of pain and recovery of joint tissues properties. The aim of this article is to describe the use of hyaluronic acid in the management of osteoarthritis of temporomandibular joint in an adolescent patient. Female patient, 15 years old, presented pain with a year of progress in the bilateral preauricular region, with increased pain at maximum aperture. Considering the clinical and imaging tests the patient was diagnosed with disk displacement with reduction with bilateral osteoarthritic and inflammatory component. Mandibular rest, liquid diet, NSAIDs were indicated and the application of intra-articular hyaluronic acid (Suprahyalâ 25 mg / 2.5 ml) bilaterally. Control was quoted at 2, 3 and 16 weeks where the patient has no spontaneous pain and tenderness. The use of hyaluronic acid is one of the most commonly used therapeutic alternatives for the management of osteoarthritis of temporomandibular joint. However, further evidence of its use in intra-articular application in adolescents and children should be incorporated.

The objective of the study was to describe our surgical and technical experience by reporting a series of 51 aneurysms treated by a pterional craniotomy as a unique approach for aneurismatic lesions of the cerebral arterial circle (Willis polygon). Retrospective study that reports a series of 37 patients (25 females and 12 males) with diagnosis of aneurismatic lesions from different localization in the Willis polygon from January 2012 to March 2015. Fifty one (51) aneurismatic lesions were treated by a unique pterional craniotomy, including 8 cases of multiple aneurismatic disease and 9 giant aneurysms. Every lesion was clipped by the same pterional modified approach. Every step of this procedure was described and illustrated sequentally. This analysis establishes that the modified frontotemporoesfenoidal (pterional) craniotomy allows surgical access to the clipping of these vascular lesions, from the circle of Willis which correlates with previous evidence. The detailed description of the surgical technique promotes a proper understanding of surgical anatomy and allows playback of this technique.
Diazepam Alters the Ultrastructure of Fetal Atrium in Rat

Published: October 2018

Diazepam (DZ) is a synthetic minor tranquilizer, used in patients with psychological and psychiatric disorders. It is a relaxing sedative, anticonvulsant and antipsychotic. DZ crosses the human placental barrier in mouse. Young women who are addicted to the drug, if they become pregnant and continue to use it, particularly during the first trimester, expose their children to psychomotor disorders. The purpose of this study was to investigate whether DZ administered during pregnancy induces ultrastructural alterations of fetal mouse myocardium. The group (DZ) of pregnant female mice of the CD-1 strain was treated with a single daily dose of 1.0 mg / kg / pc / sc of day 6 to 17 and a group (C) that received saline solution. On day 18 females of both groups were anesthetized, the fetuses were perfused by intracardiac route with 1 % paraformaldehyde and 2.5 % glutaraldehyde, the heart was removed, the atrium was dissected, fixed in 1 % OsO4, it was immersed in epoxy resin. The fine sections were contrasted with uranyl acetate and lead citrate and observed in a transmission electron microscope. In the myocytes of the fetuses of the DZ group, the sarcomers of the compact myocardium were shorter than those of the C group. Areas with disorganized myofibrils were observed. The sarcoplasmic reticulum of some myocytes had distended and fragmented cisterns, altered mitochondria, and abundant polyribosomes were observed. The changes may be due to the effect of DZ on the synthesis of actin and heavy myosin and on cytoplasmic organelles mediated by peripheral benzodiazepine receptors present on the outer membrane of the mitochondria and associated with voltage-dependent calcium channels. Ultrastructural alterations of the atrial myocardium of fetuses of mice exposed to DZ in utero may have postnatal effects.

This glandular tissue is capable of suffering all the pathologies that can affect the normotopic gland, being able to be symptomatic or asymptomatic. We present a case of lingual thyroid in a previously thyroidectomized patient who consulted for dyspnea and dysphagia in the Head and Neck Surgery Unit of the Otolaryngology Service of the Central Hospital of the Institute of Social Prevision, Asuncion, Paraguay. The patient received hormone replacement therapy, showing normal functional examination. Semiology allowed to observe a bulging of the base of the tongue. The fibroscopy showed a tongue-based tumor about 3 cm in diameter, which could be correctly evaluated with computed tomography. Suspicion of a lingual thyroid was performed with a scintigram demonstrating uptake in the oral cavity floor. Tumor excision was performed through a suprahyoid pharyngotomy, following a prophylactic tracheostomy. The Pathologic Anatomy report confirmed the diagnosis of ectopic colloid goitre.

One of the goals of hemodialysis is to maintain normal hydration status in ESRD patients. Pre hemodialysis systolic blood pressure is usually used as a clinical parameter of hydration status and to set ultrafiltration rate before Hd. It is unclear how much pre-Hd SBP correlated with hydration status. The aim was to determine correlation between pre-Hd SBP and hydration status before Hd. An observational correlation study was performed in two dialysis centers in Santiago, Chile, from January-June, 2011. Adult patients in Hd for at least three months, who gave their informed consent were included. Patients with pacemaker, amputee, hospitalized and metallic prostheses were excluded. Total-body water and overhydrated were assessed with bioimpedance spectroscopy before the first and third dialysis session of the week. Pre-Hd SBP, pre-Hd body weight, pre-Hd TBW and pre-Hd OH, were analyzed using Pearson correlation and linear regression model. 96 measurements were assessed, 52 % were male with median age 59.5 years. The correlation between pre-Hd SBP and pre-Hd overhydration was r=0.33, and total body water r=0.15, with a predicted value, R2=0.10 and R2 =0.14 respectively. Pre-Hd SBP had low correlation with pre-Hd hydration status and by itself, is not a reliable parameter to set ultrafiltration rate before Hd. Nevertheless Pre-Hd body weight predicted in 70 % the pre-Hd TBW.

Report the recurrence rate of negative pressure subdural drainage (NPSD) versus to other kind of drains (OD). Design and Methods: A study was conducted cross-sectional and we retrospectively analyzed on the database of the neurosurgical service and we looked for all surgical procedures recorded from January 2006 to December 2015. Procedures with preoperative diagnosis of subdural hematoma (SDH) were selected, with a to- tal of 364 interventions, were excluded patients with postoperative diagnosis different from SDH and eliminated those who did not have complete data, recurrence was identified, a statistical analysis was performed describing frequency measurements percentage and standard deviation, RM and chi- square was obtained by software EPIDAT 3.1. 277 surgeries were performed in 230 patients, The population was divided into two groups: the first those interventions with negative pressure subdural drainage versus a second group with other different drains, and finally we compared the recurrence rate in each group, 44 surgeries had recurrence of SDH. The proportion of recurrence was found 16 % of the surgeries, 16 % (n=7) of these were performed with negative pressure subdural drainage and the remaining 84 % (n=37) by other drainage. The reason for prevalence found was 0.36 (95 % CI , 0.15 to 0.85), with statistically significant differences (p = 0.0165). The chi-square was 5.75 for the SDH with NPSD. It was found that patients treated with NPSD have a lower risk of recurrence compared with OD, which acts as a protective factor for patients treated with this type of drain, this is statistically significant.
Epidermoid Cyst of Uvula: Presentation of Case. Review of the Literature

Published: October 2018

The epidermoid cyst is a frequent dermatological entity, being very rare its location in the oral cavity, with a higher prevalence at the level of the floor of the oral cavity. It is considered of congenital etiology, although it occurs predominantly in young adults. They are generally well circumscribed, slow growing and asymptomatic masses, although those located in the oral cavity and oropharynx can cause phonatory, swallowing and respiratory disorders. The diagnosis is clinical, being the differential diagnosis with the dermoid and teratoid cysts only possible with the histopathological study. The treatment is surgical and the prognosis is favorable without relapses. We present a case of epidermoid cyst located in uvula, in a male of 6 months of life, treated surgically, with the tumor excision by a transoral approach

Irritation fibroma are the most common form of reactive lesions found within the oral cavity. These lesions normally attain a small size and show a slow growth rate. This paper reports a case of gigantic intraoral irritational fibroma with a history of rapid growth. Complete excision was performed and the specimen was sent for immunohistochemistry (IHC) staining. It was found positive for vimentin, hence reported as irritation fibroma.

The bisphosphonates are synthetic substances of inorganic pyrophosphate that have been the basis of treatment of patients with osteolytic diseases, such as multiple myeloma, malignant hypercalcemia, Paget's disease, or patients with bone metastases. Its main pharmacological effect is inhibition of bone resorption caused by osteoclasts, which have a reduced function. Their adverse effects are infrequent but include pyrexia, impaired renal function, hypocalcemia, and more recently, maxillo-mandibular ostenecrose induced bofosfonatos. In this report we describe a clinical case of jaw osteonecrosis induced by bisphosphonates in patient with chronic kidney disease and the treatment protocol performed.

Published: October 2018

Advertising has become a critical success factor for companies. In the case of dental products, consumers primarily consider the benefits of the product before purchasing. However, there are other relevant factors in consumer interaction with the dental advertising. The aim of this article is to present the results of research on advertising and its influence on purchasing decisions of products and / or dental services. Several authors have identified factors related to successful ads, some speak about creativity and others give importance to brand management, among others. Dentists found that consumers are generally receptive to the use of advertising. Advertising can be a powerful tool for recruiting future patients and to ensure current patients, but the precepts required by dental ethics code must be respected. It is necessary further research about the implications of advertising in dental services.
Efficacy of Platelet Rich Plasma and Platelet Rich Fibrin in Periodontal Regeneration: Systematic Review.
Authors: Cid Felipe
Published: October 2018

Regeneration is defined as the reproduction or reconstruction of a lost part or injury of the body in such a way that the architecture and function of the lost or injured tissue are completely restored. The goal of regenerative periodontal therapy is to restore the structure and function of the periodontium. The positive effects of Platelet-rich plasma (PRP) are attributed to the angiogenic, mitogenic and proliferative capacities of growth factors such as platelet-derived growth factor, transforming growth factor and vascular endothelial growth factor. Platelet-rich fibrin (PRF) is a second generation platelet concentrate that allows fibrin membranes enriched with platelets and growth factors to be obtained after starting an anticoagulant-free blood collection without any biomechanical artificial modification. The objective of this review is to know the efficacy of platelet-rich plasma and platelet-rich fibrin in the periodontal regeneration of intrabony defects. The clinical implications for this autologous material are promising. Further long term, larger, multicentred randomized controlled clinical trials are required to determine the effects of PRP and PRF on the regeneration of alveolar bone due to periodontal disease.
