The aim of this study was to verify efficacy of surgical procedures and to compare both of surgical procedures through the keratinized tissue width. Methods. The

study included 20 teeth with gingival recesion, Muller class I and II. Ten teeth with gingival recession were treated with connective tissue autotransplants 3-Methyladenine clinical trial with periosteum in combination with coronary guided surgical flap (CTG group). On the contralateral side 10 teeth with gingival recession were treated with the same surgical procedures but in combination with platelet-rich plasma (CTG-PRP group). We measured the keratinized tissue width. For statistical significance we used the Student’s t-test. Results. The study reveled a statistical significance in reducing vertical deepress Stem Cells & Wnt inhibitor of recession by both used treatments. Root deepness in CTG and CTG-PRP group was 90% and 93.5%, respectively. With both surgical techniques we achieved larger zone of keratinized gingiva but with a wide zone of keratinized tissue in CTG – the

PRP group. Conclusion. The concept regeneration technique with PRP and with the stimulating influence of platele activated growth factors results in the regeneration of deep periodontal tissue as an important prerequisite for the successfull treatment of gingival recession.”
“Using numerical modeling, this work estimates sediment dispersion patterns caused by the incidence of waves in five distinct coastline contours of the Jequitinhonha River delta plain during the Late Holocene. For this study, a wave climate model based on the construction of wave refraction diagrams relative to the current boundary conditions was defined and assumed to be valid for the five coastlines. Numerical modeling from the refraction diagrams was carried out considering the angle of incidence and wave height along the coastline. This work has allowed us to reproduce past and current patterns of net longshore sediment drift defined by a conceptual model developed from the integration of sediment cores, aerial photograph

interpretation, C(14) datings and geomorphic indicators of longshore drift. These results show that, on average, current ZD1839 chemical structure wave conditions in the east-northeastern Brazilian region seem to have remained characteristically the same from approximately 5100 years BP until the present time. This type of information can be important when attempting to simulate possible future situations in terms of the long-term general behavior of the east-northeastern Brazilian coastal region.”
“A new consensus-based classification of congenital melanocytic nevi (CMN) has recently been proposed. It includes categories for projected adult size (PAS) and location, satellite nevi counts, and morphologic characteristics (color heterogeneity, rugosity, nodularity, and hypertrichosis).
