Farias, Vanessa Costa;Tesch, Ricardo de Souza;Denardin, Odilon Victor Porto;Ursi, Weber;
Dental Press Journal of Orthodontics , 2012, DOI: 10.1590/S2176-94512012000200011
Abstract: objective: early identification of craniofacial morphological characteristics allows orthopedic segmented interventions to attenuate dentoskeletal discrepancies, which may be partially disguised by natural dental compensation. to investigate the morphological characteristics of brazilian children with class iii malocclusion, in stages i and ii of cervical vertebrae maturation and compare them with the characteristics of class i control patients. methods: pre-orthodontic treatment records of 20 patients with class iii malocclusion and 20 control class i patients, matched by the same skeletal maturity index and sex, were selected. the craniofacial structures and their relationships were divided into different categories for analysis. angular and linear measures were adopted from the analyses previously described by downs, jarabak, jacobson and mcnamara. the differences found between the groups of class iii patients and class i control group, both subdivided according to the stage of cervical vertebrae maturation (i or ii), were assessed by analysis of variance (anova), complemented by bonferroni's multiple mean comparisons test. results: the analysis of variance showed statistically significant differences in the different studied groups, between the mean values found for some angular (sna, snb, anb) and linear variables (co - gn, n - perp pog, go - me, wits, s - go, ar - go). conclusion: assessed children displaying class iii malocclusion show normal anterior base of skull and maxilla, and anterior positioning of the mandible partially related to increased posterior facial height with consequent mandibular counterclockwise rotation.
Bases epidemiológicas para análise das más oclus?es morfológicas como fatores de risco no desenvolvimento das desordens temporomandibulares de origem articular
Tesch, Ricardo de Souza;Ursi, Weber José da Silva;Denardin, Odilon Victor Porto;
Revista Dental Press de Ortodontia e Ortopedia Facial , 2004, DOI: 10.1590/S1415-54192004000500006
Abstract: among the researches undertaken in epidemiology, a peculiar group of pathologies present either unknown or not totally understood origins. temporomandibular disorders (tmd) can be classified in this subgroup. three basic observational strategies have been used to approach the etiologic role of malocclusion in tmd development, inside the epidemiological repertoire. they are sectional, case-control and cohort studies. some clinical trials are conducted based on the removal of the suspect etiologic factor. based on the literature reviewed in terms of the methodology applied in the selected studies, we can infer that: the definition of possible etiological factors related to specific sub-groups of tmd is primordial not to underestimate the role of malocclusion in the development of this kind of disorders; the characterization of a normal occlusion like the one associated with the lower risk for tmd problems development can be useful, but the application of these parameters will probably result inappropriate for the resolution of a joint problem which is already established; the concept of lower risk occlusion would involve a small slide discrepancy between rcp and icp, small incisal overlap, positive overbite and no posterior crossbite. this concept is similar to the concept of normal occlusion supported for decades, although a deviation from the normal criterion instead of an absolute criterion must be tolerated; although it may be prudent to establish therapeutic morphologic goals that seek what is observed in untreated occlusions deemed normal or ideal, the establishment of an occlusion that reach all these gnathologic criteria, by means of orthodontic treatment, might be either impossible or probably unnecessary.
Possíveis fatores etiológicos para desordens temporomandibulares de origem articular com implica??es para diagnóstico e tratamento

Dental Press Journal of Orthodontics , 2010, DOI: 10.1590/S2176-94512010000300010
Abstract: the authors reviewed the factors involved in the etiology, diagnosis and treatment of temporomandibular joint disorders (tmd). although essential, specific criteria for inclusion and exclusion in tmd diagnosis have shown limited usefulness. currently, the research diagnostic criteria for temporomandibular disorders (rdc/tmd) offer the best evidence-based classification for the most common tmd subgroups. the rdc/tmd includes not only methods for physical diagnostic classification, comprised in axis i, but also methods to assess the intensity and severity of chronic pain and the levels of non-specific depressive and physical symptoms, in axis ii. although historically malocclusions have been identified as risk factors for the development of tmd-including those predominantly joint-related-in many cases the association established between these variables seems to have taken opposite directions. regarding internal tmj derangements, the results of studies on the induced shortening of the mandibular ramus, secondary to anterior articular disk displacement, indicate that repositioning the displaced disk in children or young adolescents may make more sense than previously imagined. the therapeutic use of dietary supplements, such as glucosamine sulfate, seems to be a safe alternative to the anti-inflammatory drugs commonly used to control pain associated with tmj osteoarthritis, although evidence of its effectiveness for most tmd patients has yet to be fully established.

Schnitzer, Jenniffer Aparecida;Faria, Ricardo Tadeu de;Ventura, Mauricio Ursi;Sorace, Mauren;
Acta Scientiarum. Agronomy , 2010, DOI: 10.4025/actasciagron.v32i1.71410.4025/actasciagron.v32i1.714
Abstract: the vegetative and root development of the species of brazilian orchids cattleya intermedia (john lindley) and miltonia clowesii (john lindley) using different substrates and pyroligneous extract were assessed. seedlings from in vitro propagation were transferred to vessels with: t1 -pinus bark (pi), coconut fibers (co) and charred peel of rice (cr); t2 - picocr and vegetal charcoal (ch), t3 - picocrch with the charcoal treated with pyroligneous extract (pe); t4 - cocrchep and t5 - cocrch. the materials used in substrates were placed in the same ratio. plant height, number of roots, length of the greater root, number of buddings, total fresh mass and ph were assessed seven months after experiment onset. for para c . intermedia, t3 was superior than the other treatments, with higher values for the studied parameters. t4, followed by t2, were the treatments in which the values were closer to the best treatment. for milt. clowesii the same tendency was found, although without the same magnitude in the differences among treatments. in general, pyroligneous extract incremented the vegetative and root development of the studied orchids.

Wanderley, Christina da Silva;Faria, Ricardo Tadeu de;Ventura, Maurício Ursi;
Acta Scientiarum. Agronomy , 2012, DOI: 10.4025/actasciagron.v34i2.12488
Abstract: the effect of using chemical fertilization, organic and pyroligneous extract (epl) on the seedling development of areca bamboo palm was evaluated. treatments were: t1 = no fertilizer (control), t2 = 0.1% epl, t3 = 0.2% epl, t4 = npk-20-5-20, t5 = npk-20-5-20 + 0.1% epl, t6 = npk-20-05-20 + 0.2% epl, t7 = castor bean cake, t8 = castor bean cake + 0.1% epl and t9 = castor bean cake + 0.2% epl. the epl solutions were 0.1 or 0.2%, 100 ml per pot, applied every two weeks. npk 20-5-20 chemical fertilizer was applied at three month intervals and castor bean cake organic fertilizer was applied once a month (40 g per pot for both). plant height and the number of leaves and shoots were evaluated one year after the beginning of the trial. the organic fertilizer on its own and with epl (t7, t8 and t9) produced the tallest plants and highest number of leaves. organic fertilizer with 0.1 and 0.2% epl produced the most shoots. for all variables, chemical fertilizer, both with and without epl, was less effective than organic fertilizer with epl and treatment with only epl was less effective than treatment with organic fertilizer.

Abstract: O desenvolvimento vegetativo e de raízes de espécies das orquídeas brasileiras Cattleya intermedia (John Lindley) e Miltonia clowesii (John Lindley) utilizando diferentes substratos e extrato pirolenhoso foi avaliado. Mudas produzidas in vitro foram transferidas para recipientes com: T1 – casca de pinus (Pi), fibra de coco (Co) e casca de arroz carbonizada (Ca); T2 – PiCoCa e carv o vegetal (Car); T3 – PiCoCaCar, sendo o carv o vegetal tratado com extrato pirolenhoso (EP); T4 – CoCaCarEP; e T5 – CoCaCar. Todos os materiais foram utilizados na mesma propor o. Altura da parte aérea, número de raízes, comprimento da maior raiz, número de brotos, massa fresca total e pH foram avaliados sete meses após a instala o do experimento. Para C. intermedia, o T3 foi superior aos outros tratamentos, com valores maiores para os parametros estudados. O T4 e, a seguir, o T2 foram os tratamentos nos quais os valores mais seaproximaram do melhor tratamento. Para Milt. clowesii, a mesma tendência se verificou, entretanto sem a mesma magnitude nas diferen as entre os tratamentos. De maneira geral, o extrato pirolenhoso incrementou o desenvolvimento vegetativo e radicular das orquídeas estudadas. The vegetative and root development of the species of Brazilian orchids Cattleya intermedia (John Lindley) and Miltonia clowesii (John Lindley) using different substrates and pyroligneous extract were assessed. Seedlings from in vitro propagation were transferred to vessels with: T1 - Pinus bark (Pi), coconut fibers (Co) and charred peel of rice (Cr); T2 – PiCoCr and vegetal charcoal (Ch), T3 – PiCoCrCh with the charcoal treated with pyroligneous extract (PE);T4 - CoCrChEP and T5 - CoCrCh. The materials used in substrates were placed in the same ratio. Plant height, number of roots, length of the greater root, number of buddings, total fresh mass and pH were assessed seven months after experiment onset. For Para C. intermedia, T3 was superior than the other treatments, with higher values for the studied parameters. T4, followed by T2, were the treatments in which the values were closer to the best treatment. For Milt. clowesii the same tendency was found, although without the same magnitude in the differences among treatments.
