Avaliação de cultivares de arroz de terras altas sob condições de sequeiro em Cassilândia, MS

O uso de cultivares selecionadas é uma das tecnologias de mais fácil adoção pelo agricultor, pois além de incrementar a produtividade, é um dos insumos de menor custo na produção agrícola. Assim, é fundamental obter informações sobre o desempenho de novas cultivares, nas mais diversas regiões de cultivo. Objetivou-se, neste trabalho avaliar o comportamento de cultivares de arroz de terras altas (Oryza sativa L.) (BRS Aroma, BRS Bonança, BRS Colosso, BRSMG Conai, BRSMG Curinga, BRS Soberana, BRS Talento e IAC 202), sob condições de sequeiro, na região de Cassilândia, MS. O delineamento experimental foi o de blocos ao acaso, com quatro repetições. A semeadura foi realizada em 30 de novembro de 2005, no espaçamento de 0,40 m entre linhas e 70 sementes viáveis por metro. As cultivares BRS Talento, IAC 202 e BRS Soberana apresentaram comportamento superior. As cultivares BRS Soberana, BRS Bonança, BRS Colosso, IAC 202 e BRS Talento apresentaram maior rendimento de grãos inteiros. É possível obterse boa produtividade (acima de 3.000 kg ha-1), na cultura do arroz de terras altas sob condições de sequeiro no município de Cassilândia, MS, desde que sejam utilizadas cultivares adequadas.

Histometric analysis of ligature-induced periodontitis in rats: a comparison of histological section planes

The purpose of this study was to analyze the histometry of ligature-induced periodontitis in rats at different histological section depths. Sixteen male adult Wistar rats were randomly assigned to two groups: ligature and control. In the ligature group, rats received a sterile 4/0 silk ligature around the maxillary right 2nd molar. Thirty serial sections containing the 1st and 2nd molars, in which the coronal and root pulp, cementoenamel junction (CEJ) in the mesial side of the 2nd molar, interproximal alveolar bone and connective fiber attachment were clearly visible, were selected for histometric analysis. The histological sections were clustered in groups of 10 sections corresponding the buccal (B), central (C) and lingual (L) regions of the of periodontal tissue samples. The distance between the CEJ in the mesial side of the 2nd molar and the attached periodontal ligament fibers (CEJ-PL) as well as the distance between the CEJ and the alveolar bone crest (CEJ-BC) were determined. From CEJ-PL and CEJ-BC distances measured for each specimen, the measurements obtained in the B, L and C regions were recorded individually and together. Data were submitted to statistical analysis. Significant differences (p<0.001) were observed between the control and ligature groups regarding CEJ-PL (0.05 mm and 0.26 mm, respectively) and CEJ-BC (0.47 mm and 0.77 mm, respectively) measurements. Regarding the depth of the buccal, central and lingual planes, the means of CEJ-PL and CEJ-BC of both groups showed no statistically significant differences (p>0.05). In conclusion, the selection of 10 serial sections of the central region of periodontal tissue samples at any depth can be considered as representative for the evaluation of periodontal ligament fiber attachment and bone loss in ligature-induced periodontitis in rats.

Hyperbaric oxygen therapy treatment for the fixation of implant prosthesis in oncology patients irradiated

doi: 10.1111/j.1741-2358.2012.00636.x Hyperbaric oxygen therapy treatment for the fixation of implant prosthesis in oncology patients irradiated Objectives: This study aimed to present a clinical report of an irradiated oncologic patient who underwent hyperbaric oxygen therapy to be rehabilitated with implant-supported prosthesis. Materials and Methods: A 67-year-old man was admitted at Oral Oncology Center (FOA-UNESP) presenting a lesion on the mouth floor. After clinical evaluation, incisional biopsy and histopathological exam, a grade II squamous cell carcinoma was diagnosed. The patient was subjected to surgery to remove the lesion and partial glossectomy. Afterwards, the radiotherapy, in the left/right cervicofacial area of the supraclavicular fossa, was conducted. After 3 years of the surgery, the patient was submitted to hyperbaric oxygen therapy. Then, four implants were installed in patients mandible. Five months later, an upper conventional complete denture and lower full-arch implant-supported prosthesis were fabricated. Conclusion: The treatment resulted in several benefits such as improving his chewing efficiency, swallowing and speech, less denture trauma on the mucosa and improving his self-esteem.
