Objectives: Treatment of osteoarthritis (OA) using autologous conditioned serum (ACS) has become in recent years an alternative to consider in the approach of the degenerative joint disease of the knee. There is no support in the literature for the use of ACS for the treatment of OA of the temporomandibular joint (TMJ), although the promising results obtained in human patients with knee joint disease as well as in animal studies are opening the way for its use at the TMJ. The aim of this paper is to conduct a review of the published literature regarding the use of the ACS for the treatment of OA in humans, considering the level of scientific evidence, and following the principles of the evidence-based medicine and dentistry. Material and Methods: A PubMed-MEDLINE search was carried out of articles published between 1980 and 2011. After an initial search, a total of 102 articles were obtained, followed by a selection of the most relevant articles according to the topic; a total of 8 articles were selected, which were stratified according to their level of scientific evidence using SORT criteria (Strength of Recommendation Taxonomy). Results: At the time of this review, there is no available literature referring the use of ACS at the TMJ. However, the use of the ACS in other joints is well documented, both experimentally and clinically, in humans and animals. The reviewed articles, with a level of evidence 1 and 2 according to the SORT criteria, have generally promising results. Discussion and Conclusions: The use of ACS in the treatment of OA in joints other than the TMJ, is endorsed by the level of evidence found in the literature, which opens the door to future studies to determine the feasibility of the use of the ACS in the treatment of degenerative OA that affects TMJ. Key words:Osteoarthritis, temporomandibular joint, autologous conditioned serum.

Objetives: The development of treated implant surfaces, added to the increase of the aesthetic requirements by the patients has led to a change in the treatment protocols as well as the development of techniques such as the one-fase implants and the immediate prosthetic loading. One of the usual contraindications of the implant treatment is the presence of periapical disease associated to the tooth to be replaced. The aim of this paper is to review the published literature on immediate implant placement in extraction sockets of teeth with periapical pathology, considering the level of scientific evidence, and following the principles of medicine and evidence-based Dentistry. Material and Methods: A search of articles published between 1982 and 2012 was conducted. The search terms immediate, dental implant, extraction, infected, periapical pathology were used. Search was limited to studies in animals and humans, published in english language. Results: 16 articles were selected from a total of 438, which were stratified according to their level of scientific evidence using the SORT criteria (Strength of Recommendation Taxonomy). Studies in both animals and humans presented high rates of implant survival, but human studies are limited to a small number of cases. Discussion and Conclusions: There is a limited evidence regarding implant placement immediately to the extraction of teeth affected by chronic periapical pathology. Following analysis of the articles, and in function of their scientific quality, a type B recommendation is given in favor of the immediate implant placement in fresh sockets associated to periapical infectious processes. Key words:Immediate implant, periapical pathology.

Introduction: The appearance of vascular anomalies in the orofacial area is a common condition, which represents about 50% of these malformations. Traditional treatment approach, such as surgery and chemical sclerosis has been given way to a few less-invasive options, as the use of the 810nm diode laser to induce the sclerosis of the venous malformation by intralesional photocoagulation. Objectives: The objective of this study was to determine the efficacy of the diode laser in the intralesional treatment of the orofacial venous malformations (OFVM), describing the recommended surgical approach, as well as to report the main associated complications. Patients and Methods: 10 cases of OFVM, diagnosed and treated at the Oral Surgery Department of the Dental Clinic of the University of Barcelona, between January, 2009 and April, 2011. Every case was treated under local anesthesia, performing at least one intralesional session of diode laser, applying an 1W active optic fiber, in continuous mode, inserted into the interior of the lesion through an intramuscular needle, from the deepest portion to the surface of the lesion. Postoperative medication was indicated and follow-up visits were perform during a period of at least 6 months. Results: Of a total of 10 cases of OFVM, mean age of 25.4 years, 8 required just a single session with intralesional laser diode, before the clinical verification of a total reduction of size of the lesion. In 2 of these cases, were needed at least 2 sessions of intralesional photocoagulation to reach a satisfactory cosmetic result. No complications of any kind occurred. After a follow-up period of at least 6 months only a case of recurrence was described. Discussion and Conclusions: The advantages associated to the use of non-invasive techniques in the treatment of OVM, along with the success rate and low number of relapses, shows the use of the diode laser as a therapy to be considered in the treatment of these lesions. A higher case mix would be essential for definitive conclusions. Key words:Diode laser, hemangioma, orofacial venous malformation.
