Miniplacas de ancoragem no tratamento da mordida aberta anterior

INTRODUÇÃO: o relato de caso apresentado descreve um tratamento ortodôntico auxiliado por miniplacas, de uma paciente adulta que apresentava mordida aberta anterior acentuada, rotação horária da mandíbula, biprotrusão e ausência de selamento labial. Após a extração dos primeiros molares e retração dentária superior e inferior, associada ao controle vertical propiciado pelas placas, ocorreu uma pequena rotação anti-horária da mandíbula e a correção da mordida aberta anterior, com significativa melhora facial. OBJETIVO: o presente relato corrobora as evidências atuais quanto à eficiência do uso de miniplacas de titânio como ancoragem temporária, especialmente em situações de correções de grande amplitude, envolvendo um problema vertical.

Biomecánica da movimentação ortodôntica--resposta inicial dos tecidos periodontais.

There occurs a biological response of the tissues of dental support, in answer to the external physiological forces and those realized during clinical treatments with orthodontical purposes. These forces differ from the first ones because they are continuous and time dependent. A great dental mobility is related to the degree of tissue organization of the periodontium system and the orthodontical movement must utilize this exceptional capacity of renewal and adaptation of the periodontium structures adequately. Therefore, through histological means a search was made to evaluate the succession of alterations of the periodontium system after the application of an orthodontical force on the molars of young rats and to interpret the standards of horizontal mobility and their consequences on the periodontium structures, biologically. An orthodontic force was applied on young rats utilizing steel wire placed in a ring form on a contact point between the first and second lower molars. The animals were sacrificed after 30 minutes, 1, 2, 6, 12, 24, 48, 72, 96 and 168 hours after the placement of the metal ring. After technical preparation, the microscopic slides were examined and the results were compared. In all the sections there was evidence of an intense metabolic activity. A gradual evolution of modification on the phenomenons had occurred.

Estudo retrospectivo dos procedimentos anestésicos realizados em cães e gatos submetidos a neurocirurgias

Neurosurgeries are frequent in the routine of veterinary hospitals and, therefore, knowledge of the different anesthetic protocols to be used for each patient is necessary to prevent the morbity and mortality in the after and trans-surgical period. The objectives of this study were to evaluate the anesthetic protocols used in patients undergoing neurosurgeries; the results of those protocols; the rate of complications, and if those complications are related to the duration of the anesthesia time. We studied the anesthetical data of 52 dogs and two cats submitted to neurosurgery between January of 2003 and December of 2006, in the Veterinary Hospital of UEL. Findings showed that the main protocols used were propofol for induction and halothane or isofluorane for maintenance of the anesthesia. These protocols induced adequate anesthesia for the surgical procedure and did not occur complications during the anesthetic period in 37/54 (68,5%) of the cases. 7/19 (36.8%) of the complications observed occurred in patients submitted to anesthesia with halothane and 8/32 (25.2%) in patients with isofluorane. The complication most observed in this study was bradicardy, which occurred in 15/54 (27.8%) of the patients. Two deaths occurred in patients submitted to slot cervical. Good knowledge of the neurological disease and of surgical and anesthetic techniques are essential to prevent alterations in the central nervous system caused by the drugs, disease or association of these factors.

Modificações no periodonto de ratos diabéticos após a movimentação ortodôntica

Aim: The aim of this study was to evaluate the periodontal ligament changes after induced dental movement of the upper incisor in diabetic rats. Methods: Twenty Wistar rats (Rattus norvegicus) with 105 days of age were used. The rats were divided in four groups: C - normoglicemic animals not submitted to dental movement; CAO - normoglicemic animals submitted to dental movement; D - diabetic animals not submitted the dental movement; DAO - diabetic animals submitted to dental movement. The animals had remained with dental movement devices during 5 days. The number of sanguine vessels and the thickness of the periodontal ligament were evaluated at cervical, medium and apical histological cut regions. Results and Conclusion: At tension side, the dental movement in the animals of group CAO resulted in a thicker periodontal ligament (17.64% apical, 39.28% medium, 51.35% cervical) when compared to C group (p < 0.05 for medium and cervical area). Group DAO exhibited an increase of periodontal ligament thickness of 50.55% (apical), 48.14% (average) and 50% (cervical) when compared to group D (p < 0.05). The periodontal ligament sanguine vessels number did not differed significantly for all groups (p < 0.05). At tension side, bone reabsorption lacunae were observed in CAO, D and DAO groups. The pressure side was not examined in this study phase.

Valores Referenciais para Procedimentos Odontológicos (VRPO) em Ortodontia

Introduction: The cost of orthodontic treatment is a very important issue. The aim of this study was to analyze the current Indicative Values for Dental Procedures (IVDP) for orthodontic procedures. Methods: Laws, dental entities papers and scientific literature were utilized. Results: Laws are too general and only offer abstract parameters when define remunerations. Current IVDP vary in the same State, according to the consultant entity. Dental entities interpret that general clinicians can practice Corrective Orthodontics, but new scientific studies begin to question this understanding. The Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR) suggests that IVDP for orthodontic specialty must be formulated. Conclusion: Current IVDP are not standardized and are below the correct values for orthodontic procedures, because they are the mean of general clinicians and orthodontists remunerations; and ABOR is legally and ethically supported to claim specific IVDP for orthodontic specialty.

Diferentes procedimentos na determinação de indicadores internos para estimativa de produção fecal e fluxo duodenal de matéria seca em bovinos

Times of in situ incubation (144 and 288h) for determination of internal markers IADF and INDF and the effects of differents procedures (wash or not the nylon bag every 72h incubation) was evaluated in samples of diet, duodenal digesta and cattle feces. The duodenal flow dry matter and fecal production utilizing the internal markers to compare with the external marker chromium oxide there was estimated. The animals were fed with sorgum silage, concentrate or urea. In this experiment, a latin square design was used, in a factorial scheme (two times of incubation × two processing nylon bag). No was observed effect of the incubation time or processing in the internal markers INDF and IADF concentration and the in situ incubation after 144h is adequate to reproduce the indigestible markers fraction in samples. For fecal production estimation, the external marker chromium oxide presented similar result (1.26 kg day-1) as the total fecal collection (1.49 kg day-1). Both the internal markers overestimate the duodenal flow dry matter when compared with the external marker chromium oxide.

Acupuntura: Um auxílio efetivo em procedimentos de fertilização in vitro?

The purpose of the present study was to evaluate the impact of acupuncture on in vitro fertilization outcomes of patients undergoing acupuncture during embryo transfer. A retrospective study was realized with records of 30 patients undergoing acupuncture and 108 patients not undergoing acupuncture during embryo transfer. The data was compared to verify the differences onto fertilization, embryo cleavage, pregnancy and abortion rate. To the statistical evaluation the X2 Test was performed, set as significant p<0.05. There was no statistical significance difference in any feature analyzed among the groups, although the acupuncture group presented higher pregnancy rate and lower abortion rate. Acupuncture did not presented positive or negative statistical relevant effects into the outcomes of in vitro fertilization procedures. Regardless this result, the present study did not exclude the possibility of acupuncture administration as a tool to pain relief during other procedures, as the transvaginal ultrasound-guided oocyte retrieval. © Todos os direitos reservados a.
