ABSTRACT
Different periodontal surgical techniques have been proposed for the treatment of periodontal recessions. Among these, the graft of gingival connective tissue stands out for the high predictability of success. This work compared the clinical outcomes of treatment of periodontal recessions, using the gingival connective tissue grafts and acellular dermal matrix. A total of 72 recessions constituted the sample, divided equally into 2 groups. Group 1: treated with acellular dermal matrix graft (MDA) associated with the displaced: Group 2: treated with gingival connective tissue graft, also associated with the flap offset coronally. We evaluated the clinical parameters of probing depth, insert, clinical periodontal recession towards coronal-apical diameter mesio-distal of recessions, keratinized and mucosa thickness flap and influence of grafts in relation to root coverage. The initial measures were compared to those obtained with 45, 90 and 120 days after surgery. No statistically significant differences were found between the groups in terms of reduction of periodontal recessions, keratinized and mucosa flap thickness and of grafts in relation to root coverage. The Group 2 (CG) showed statistically significant reduction in the depth of drilling and clinical level of insertion, compared to group 1 (MDA). However, these differences were not clinically relevant. It was concluded that both the gingival connective tissue graft as the acellular dermal matrix can be used in the treatment of periodontal recessions, with a high predictability of success.

Objective: To investigate the water extract from Radix (Flemingia philippinensis Merr et Rolfe Decoction.) Effect
of sciatic nerve gastrocnemius muscle Characteristics of isolated frog. Methods: The dissected lesion of sciatic nerve gastrocnemius muscle was infused with 0.9% saline, 0.125g / mL, 0.25g / mL, 0.5g / mL jelly extract, and the RM6240 bio-signal collector was used to measure each The infiltration depth of 5 minutes, infiltration for 10 minutes, infiltration of 15 minutes at each time point of the gastrocnemius muscle contraction threshold strength (measured at each time point 5 times) and complete single contraction curve (measured at each time point 25) Systolic rate, systolic rate, rate of contraction, and latency. Results: The systolic threshold intensity of the gastrocnemius muscle increased with the increase of the concentration of the extraction fluid, but less than the pre-treatment level (P <0.01, P <0.05). If the concentration and time (P <0.05). At the same time, the systolic amplitude, systolic rate and diastolic rate increased first and then decreased with the increase of the concentration of the extract (P <0.01, P <0.05). The latency of the sciatic nerve of the sciatic nerve was affected by the concentration of the drug in the infiltration solution, which decreased first and then increased with the increase of the drug concentration. Conclusion: The systolic characteristics of skeletal muscle are affected by the weight of the components. Low concentration of salt water extract in a short time to improve the ability of skeletal muscle contraction, treatment time is too long or too high concentration of crude drugs will make the skeletal muscle contractility weakened, and even inhibit the skeletal muscle contractility, and affect the nerve Muscle excitement signal transmission.
Background: Langerhans cell histiocytosis is a relatively rare unique disease process characterized by an abnormal proliferation of immature dendritic cells usually affecting children and young adults.
Discussion: Histiocytosis are rare diseases of great biological variability and a wide range of clinical manifestations. The first manifestations of LCH may occur in the oral cavity may vary from a continuous gingival infection or a dental abscess to necrotizing ulcerating defects or a painful jaw swelling.The criteria for diagnosis of LCH includes identification of the characteristic clinical features histopathological, Immunohistochemical findings. Various treatment modalities has been adopted including wide surgical excision along with radiotherapy,chemotherapy ,isolated radiotherapy and use of alkalizing agents.
