Tooth Discoloration Induced by Endodontic Phenothiazine Dyes in Photodynamic Therapy

Objective: This study sought to assess if discoloration of tooth structures occurs after photodynamic therapy (PDT) and to determine the efficacy of a protocol to remove the photosensitizers. Background data: PDT has been used in root canal treatment to enhance cleaning and disinfection of the root canal system. PDT uses a low power laser in association with a dye as a photosensitizer. Photosensitizers can induce staining of the dental structures, resulting in an unaesthetic appearance. Methods: Forty teeth were randomly divided into four groups according to the photosensitizer used and pre-irradiation time: 0.01% methylene blue for 5 min (MB5); 0.01% methylene blue for 10 min (MB 10); 0.01% toluidine blue for 5 min (TB5); and 0.01% toluidine blue for 10 min (TB 10). Specimens were irradiated with a 660 nm diode laser with a 300 mu m diameter optical fiber, at 40 mW power setting for 3 min. Immediately after, the photosensitizers were removed with Endo-PTC cream +2.5% sodium hypochlorite (NaOCl). The shade was measured by a Vita Easyshade spectrophotometer based on the CIELAB color system (L*a*b* values) at three different experimental times: before PDT (T0), immediately after PDT (T1), and after removal of the photosensitizer (T2). Results: The results showed a decrease in the averages of the L*a*b* coordinate values after PDT (T1) in all the groups, when compared with the number at T0, with a significant statistical difference in group MB10. After photosensitizer removal (T2), all the values of the coordinates increased with significant statistical differences (p < 0.05) between T1 and T2 in L* and a*. Conclusions: It can be concluded that both methylene blue and toluidine blue dyes cause tooth discoloration, and that Endo-PTC cream associated with 2.5% NaOCl effectively remove these dyes, regardless of the pre-irradiation time used for PDT.

Digestibilidade e desempenho em cordeiros alimentados com dietas contendo feno de amoreira

The experiment was conducted to evaluate the intake, the digestibility and the performance of lambs fed with diets containing 0; 12,5 and 25% of mulberry hay in substitution of the concentrate. It was used a total of 24 lambs Ile de France breed, non castrated, average age 60 days and and 15 kg of body weight, confined, distributed in a completely randomized design. Voluntary intake of nutrients was not altered (P>0.05) by different percentages of mulberry hay inclusion in the concentrate, except ether extract which decreased linear (P<0.01). The digestibility of nutrients, days on feeding, daily weight gain and the feed conversion, were also not affected (P>0.05). The partial substitution of the concentrate, based on soybean meal and corn grain, by mulberry hay up to 25% does not compromise the intake, the digestibility of nutrients and the performance of diet of feedlot lambs.

Efeito da tosquia estratégica no comportamento ingestivo de ovelhas Ile de France em pastagem de capim vaquero (Cynodon dactylon cv Vaquero) durante a estação de monta

The experiment evaluated the effects of strategic shearing on feeding behavior in Ile de France ewes in Bermudagrass (Cynodon dactylon) grazing during breeding season. A total of 20 ewes, female, Ile de France breed, 4 years old, 71.10 kg of body weight, in grazing, in a completely randomized design with two treatments and ten repetitions, in which the treatments were composed by shorn and non-shorn animals. The length of the breeding season was 90 days, where the evaluations occurred in the 86th, 87th and 88th day of the experimental period. The grazing time (6.50 hours), rumination (1.59 hours) and idle (3.97 hours) have not changed (P> 0.05) by strategic shearing of the animals, as well as the frequency and the time by frequency grazing (18.33 grazing and 21.49 min/grazing), rumination (10.71 ruminations and 8.83 min/rumination) and idle (18.83 idles and 12.66 min/idle). In the same way, the number of bits per minute (26.37 bits) and the total daily bits (19.116 bits) of the animals were not affected. Thus, the strategic shearing in Ile de France ewes in Bermudagrass grazing during the breeding season does not alter animal feeding behavior.

Relações Públicas: a importância das relações humanas

This monograph has as objective to study the human relations and the Public Relations in the contemporary time in witch the new technologies of the information got closer to the various existent cultures, but who make of the informative society of the global era, the expansion of the capital and of the culture of the more value. Man kind is backing away from the human relations, because the social interactions in the global world are done by objects such as the television, the internet and the telephone in witch cases the subjectivity and the human contact are traded for the informative quantity, because man kind doesn’t have anymore time to think, reflect and to exchange information. Man kind isolates itself and fills it’s subjective emptiness with the products offered by the neoliberal capitalism. The public relations in the organizations seek the human values created from a complex network of social interactions in all the heterogeneous of the organization. Through the communication the public relations tries to manage the relationships with the dialogical communication, between the public-organization, to harmonize the conflicting differences of the organizational environment. Thus, the public relations has to assume the roll of the information manager, and administrator of the human relations in this new global world, informative and that functions from the capital

Geologia do alvo e da mina Sol Nascente, município de Rio Crespo, Rondônia

Eight Mesoproterozoic granite suites are recognized in the Rondônia Tin Province, called Serra da Providência Intrusive Suite (1606-1532 Ma), Rio Crespo Intrusive Suite (1500 Ma), St. Anthony Intrusive Suite (1406 Ma), Teotonio Intrusive Suite (1387 Ma ), Santa Clara Intrusive Suite (1082-1074 Ma) and Younger Granites of Rondônia Intrusive Suite (998-974 Ma), represent successive magmatic type A (anorogenic) and the intra-plate basement rocks intruded in the metamorphic complex named Jamari separated into two distinct lithologic associations, a ortogneiss (U-Pb from 1.76 to 1.73 Ga) and a paragneiss (1675 + / - 12 Ma). Tin mineralization are widely found in the Tin Province and are associated with granitic intrusions known Mesoproterozoic more closely with the last two magmatic events, represented by the Santa Clara and Younger Granites of Rondônia. The tin mineralization are of primary and secondary, with the primary form deposits of different structural styles and is presented in the form of endo-or exogreisens, veins, stockworks and pegmatites. The secondary mineralization are related to natural processes of weathering and erosion of primary rocks, leading to placer deposits classified as colluvial, eluvial and colluvial-alluvial. The Target Alvo Sol Nascente is located in the central-eastern Rondônia Tin Province and has basement rocks of the metamorphic-magmatic region represented by Jamari Complex intrusive suites and Sierra Providence and Rio Crespo. The last tectonic event spa in the area was responsible for the intrusion of Younger Granites of Rondônia (São Carlos and Caripuanã Massifis). The anomalous levels of tin, sufficient to operate (Mina Rising Sun), indicate that there was possibly mineralization event, evidenced by pegmatite veins well defined, easily found relatively close to mine. Plaque deposits associated with Quaternary sedimentary sequences can also be observed

Lesão endoperio: apicectomia com abordagem palatina: Relato de caso clínico com 30 meses de acompanhamento

Traditionally, the apicoectomies are carried out with the vestibular approach for visibility and easiness of access. The aim of this study was to present a case report of a patient with extensive injury endo-periodontal opted for the surgical access through a palatal incision. The patient presented with abscess drainage via periodontal ligament. The periodontal probing coincident with the radiographic apex in mesial tooth on dental element 22. Radiographically it was noted that the periapical lesion extended from the distal of the tooth 11 to the mesial of tooth 23. The tooth 22 had undergone endodontic treatment and showed signs of shutter material extravasation. It was decide to carry out an approach by the Palatine of the tooth to prevent gingival. After the flap elevation, the injury was debrided and apicoectomy was performed. The patient reported no pain or discomfort after surgery. Furthermore, as follow-up of 30 months there was total remission of signs and symptoms presented initially and absence of gingival recession. Therefore, according to the results showed in this case report, it is suggested that the Palatine access is an alternative approach that can be successfully employed in cases of apicoectomies in order to avoid the occurrence of gingival recessions.

Radiopacity and flow of different endodontic sealers

The present study evaluated the radiopacity and flow of different endodontic sealers: AH Plus, Endo CPM, MTA Fillapex, Sealapex, Epiphany, and Epiphany SE. For the radiopacity test, six specimens measuring 10mm in diameter and 1mm in thickness were fabricated from each material. They were radiographed on an occlusal film alongside an aluminum step wedge. Radiographs were digitized to determine the radiopacity equivalence in millimeters of aluminum. To evaluate the flow, a 120 g load was placed on top of a glass slab containing 0.05 } 0.005ml of sealer. The diameters of each material were measured (mm) with a caliper and samples were photographed. Digitized images were analyzed using the UTHSCSA Image Tool for Windows software, to determine the sealer area (mm2). Data were submitted to ANOVA and Tukey's test at 5% significance. AH Plus and Epiphany SE presented the greatest radiopacity (12.5 mm Al and 12.0 mm Al, respectively) (p>0.05), followed by Epiphany (9.6 mm Al) and Fillapex (8.9 mm Al). Endo CPM (5.46 mm Al) and Sealapex (5.51 mm Al) presented lower radiopacity. MTA Fillapex presented significantly higher values of flow than other sealers (33.11 mm and 844.9 mm2). AH Plus, Epiphany, and Epiphany SE had similar values. Endo CPM (21.05 mm and 342.8 mm2) and Sealapex (19.98 mm and 352.5 mm2) presented the lowest flow values (p>0.05). All sealers presented radiopacity and flow values according to ISO and ANSI/ADA recommendations.
