Desempenho do inhame (taro) em plantio direto e no consórcio com crotalária, sob manejo orgânico.

Estudaram-se os efeitos do plantio direto em cobertura morta de aveia-preta e do consórcio com Crotalaria juncea, em sistema orgânico de produção de inhame, em ensaio na EE de Nova Friburgo(Pesagro-Rio), região serrana do estado do Rio de Janeiro. Utilizouse o delineamento de blocos ao acaso com quatro repetições, em esquema fatorial 2 x 2, onde os tratamentos corresponderam ao: modo de plantio (direto ou convencional) e modo de cultivo (monocultivo ou consórcio com crotalária). O cultivo consorciado com a leguminosa promoveu maior altura nas plantas do inhame, assim como reduziu a queima de folhas pelos raios solares. A população infestante de ervas espontâneas foi mais efetivamente controlada com a combinação entre consórcio e plantio direto. Nenhum dos tratamentos influenciou a produtividade do inhame, que foi considerada satisfatória, indicando o potencial do manejo orgânico adotado

Steroidal And Non-steroidal Cyclooxygenase-2 Inhibitor Anti-inflammatory Drugs As Pre-emptive Medication In Patients Undergoing Periodontal Surgery

The aim of the present study was to compare the pre-emptive use of a cyclooxygenase-2 (COX-2) inhibitor with a well established steroidal anti-inflammatory drug for pain and edema relief following periodontal surgery for crown lengthening. Thirty patients requiring periodontal surgery were randomly assigned to receive one of the following medications: selective COX-2 inhibitor or steroidal antiinflammatory drug, 60 min before the surgical procedure. To examine patient anxiety, a Corah's dental anxiety scale was applied before surgery. Using a visual analog scale, the extent of pain/discomfort during the trans-operative period and immediately after the surgery was measured. Additionally, intensity of pain/discomfort and edema were examined 4, 8, 12 and 24 h postoperatively. With regard to anxiety, no statistical differences between the groups were observed (p>0.05). With respect to the extent of pain/discomfort during the trans-operative, immediate and late postoperative period, data demonstrated no significant differences (p>0.05) between the COX-2 inhibitor and steroidal groups. With regard to edema, intragroup analysis did not reveal any statistically significant difference (p>0.05) during the 24 h following surgery in either group. In conclusion, both anti-inflammatory drugs presented a similar potential for pain and edema relief following periodontal surgery.236621628Pontoriero, R., Carnevale, G., Surgical crown lengthening: A 12-month clinical wound healing study (2001) J Periodontol, 72, pp. 841-848fDeas, D.E., Moritz, A.J., McDonnell, H.T., Powell, C.A., Mealey, B.L., Osseous surgery for crown lengthening: A 6-month clinical study (2004) J Periodontol, 75, pp. 1288-1294Vogel, R.I., Gross, J.I., The effects of nonsteroidal anti-inflammatory analgesics on pain after periodontal surgery (1984) J Am Dent Assoc, 109, pp. 731-734Silva, R.C.L., Riera, R., Saconato, H., Lumiracoxib for acute postoperative dental pain: A systematic review of randomized clinical trials (2011) São Paulo Med J, 129, pp. 335-345Piecuch, J.F., What strategies are helpful in the operative management of third molars?

Hydroxyapatite/β-tricalcium Phosphate And Enamel Matrix Derivative For Treatment Of Proximal Class Ii Furcation Defects: A Randomized Clinical Trial

Objective To clinically evaluate proximal furcations treated with hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) isolated or combined with enamel matrix derivative (EMD). Material and Methods Thirty patients, presenting at least one proximal class II furcation defect, probing pocket depth (PPD) ≥5 mm and bleeding on probing, were included. The defects were assigned to the HA/β-TCP group (n = 15); open-flap debridement (OFD) + HA/β-TCP filling, or, HA/β-TCP-EMD group (n = 15); OFD + HA/β-TCP + EMD filling. Plaque (PI) and gingival index (GI), PPD, relative gingival margin position (RGMP), vertical and horizontal attachment level (RVAL and RHAL), vertical and horizontal bone level (RVBL and RHBL), and furcation diagnosis were evaluated at baseline and at 6 months. Results Both groups presented improvements after therapies (p 0.05). At 6 months, the gains in rVCAL in the HA/β-TCP and HA/β-TCP-EMD groups were 1.47 ± 0.99 and 2.10 ± 0.87 mm, while the RHCAL gains were 1.47 ± 1.46 and 1.57 ± 1.58 mm (p > 0.05). The RVBL and RHBL gains for the HA/β-TCP and HA/β-TCP-EMD group were 1.47 ± 1.13 and 1.70 ± 1.26 mm, and 1.90 ± 1.11 and 1.70 ± 1.37 mm respectively (p > 0.05). The HA/β-TCP-EMD group showed seven closed furcations versus four in the HA/β-TCP group (p > 0.05). Conclusion Both treatments lead to improvements in all clinical variables studied in the present trial. However, the closure of proximal class II furcation defects is still unpredictable. © 2012 John Wiley & Sons A/S.403252259Aguero, A., Garnick, J.J., Keagle, J., Steflik, D.E., Thompson, W.O., Histological location of a standardized periodontal probe in man (1995) Journal of Periodontology, 66, pp. 184-190Ainamo, J., Bay, I., Problems and proposals for recording gingivitis and plaque (1975) International Dental Journal, 25, pp. 229-235Anderegg, C.R., Alexander, D.C., Freidman, M., A bioactive glass particulate in the treatment of molar furcation invasions (1999) Journal of Periodontology, 70, pp. 384-387Armitage, G.C., Development of a classification system for periodontal diseases and conditions (1999) Annals of Periodontology, 4, pp. 1-6Armitage, G.C., Svanberg, G.K., Löe, H., Microscopic evaluation of clinical measurements of connective tissue attachment levels (1977) Journal of Clinical Periodontology, 4, pp. 173-190Avera, J.B., Camargo, P.M., Klokkevold, P.R., Kenney, E.B., Lekovic, V., Guided tissue regeneration in class II furcation involved maxillary molars: A controlled study of 8 split-mouth cases (1998) Journal of Periodontology, 69, pp. 1020-1026Bowers, G.M., Schallhorn, R.G., McCkain, P.K., Morgan, R., Reynolds, M.A., Factors influencing the outcome of regenerative therapy in mandibular class II furcations: Part i (2003) Journal of Periodontology, 74, pp. 1255-1268Carranza, F.A., Jolkovsky, D.L., Current status of periodontal therapy for furcation involvements (1991) Dental Clinics of North America, 35, pp. 555-570Casarin, R.C., Ribeiro, E.D.P., Nociti, Jr.F.H., Sallum, A.W., Sallum, E.A., Ambrosano, G.M., Casati, M.Z., A double-blind randomized clinical evaluation of enamel matrix derivative proteins for the treatment of proximal class-II furcation involvements (2008) Journal of Clinical Periodontology, 35, pp. 429-437Casarin, R.C., Ribeiro, E.D.P., Ribeiro, F.V., Nociti, Jr.F.H., Sallum, A.W., Sallum, E.A., Casati, M.Z., Influence of anatomic features on the effectiveness of enamel matrix derivative proteins in the treatment of proximal class II furcation involvements (2009) Quintessence International, 40, pp. 753-761Casarin, R.C.V., Ribeiro, E.D.P., Nociti, Jr.F.H., Sallum, A.W., Ambrosano, G.M.B., Sallum, E.A., Casati, M.Z., Enamel matrix derivative proteins for the treatment of proximal class II furcation involvements: A prospective 24-month randomized clinical trial (2010) Journal of Clinical Periodontology, 37, pp. 1100-1109Chitsazi, M.T., Farahani, R.M., Pourabbas, M., Bahaeddin, N., Efficacy of open flap debridement with and without enamel matrix derivatives in the treatment of mandibular degree II furcation involvement (2007) Clinical Oral Investigation, 11, pp. 385-389Donos, N., Glavind, L., Karring, T., Sculean, A., Clinical evaluation of an enamel matrix derivative in the treatment of mandibular degree II furcation involvement: A 36-month case series (2003) International Journal of Periodontics and Restorative Dentistry, 23, pp. 507-512Garnick, J.J., Keagle, J.G., Searle, J.R., King, G.E., Thompson, W.O., Gingival resistance to probing forces.

Ocorrência da ferrugem da videira em Minas Gerais

A ferrugem da videira causada por Phakopsora euvitis Ono constitui-se numa ameaça às regiões produtoras de uva em função do potencial destrutivo da planta. A doença foi detectada no Brasil, pela primeira vez, em 2001. Atualmente, ela ocorre no Paraná, Mato Grosso do Sul, São Paulo, Rio Grande do Sul, Mato Grosso, Roraima, Espírito Santo e Santa Catarina. Em abril de 2010, observaram-se na estação experimental da Unimontes, Janaúba, Minas Gerais, plantas da cv. Niágara rosada com sintomas típicos da doença. A análise dos sintomas e a caracterização dos urediniósporos sésseis, levemente equinulados, com formato oval, ou elipsoide formado em urédias subepidérmicas na origem, inrompentes e com paráfises circundantes dorsalmente, levaram à diagnose de Phakopsora euvitis como o agente causal da doença. Este é o primeiro relato da doença no Estado de Minas Gerais
