Lateral dislocation with occurrence of buccal bone plate fracture in a deciduous tooth: clinical case study / Luxação lateral com ocorrência de fratura de tábua óssea vestibular em dente decíduo: relato de caso clínico

ABSTRACT Dental trauma can happen at any stage of life; however, it is very common in preschool and school aged children. Dislocation injuries in the primary dentition are the most commonly described traumatic dental injuries in the literature. Tooth displacement in the primary dentition is favored due to the greater porosity and resilience of the alveolar bone. Through the study of a clinical case, this article presents the clinical conduct performed in the case of trauma of lateral dislocation with involvement of a fracture of the buccal bone plate in order to assist the clinical practice of dentists who care for children. The treatment carried out in this clinical case study took into account the magnitude of the displacement, the degree of development of the tooth and its relationship with the permanent germ, the length of time since the trauma, and the degree of cooperation of the child in the face of the suggested treatment. This treatment does not only involve emergency intervention; the patient must undergo a radiographic clinical follow-up and control after 30, 60 and 120 days, as well as annually, until the Exfoliation of the deciduous tooth. The child's health was restored aesthetically and functionally.

RESUMO Traumatismos dentários podem acontecer em qualquer fase da vida, entretanto, é muito comum em crianças na idade pré-escolar e escolar. As lesões de luxação na dentição decídua são as lesões dentárias traumáticas mais comumente descritas na literatura. O deslocamento dentário na dentição decídua é favorecido devido à maior porosidade e resiliência do osso alveolar. Através do relato de caso clínico, o artigo apresenta a conduta clínica realizada diante um trauma de luxação lateral com acometimento de fratura de tábua óssea vestibular no intuito de auxiliar a prática clínica de cirurgiões-dentistas que atendem crianças. O tratamento realizado neste caso clínico levou em consideração a magnitude do deslocamento, o grau de desenvolvimento do elemento dentário e sua relação com o germe do permanente, o tempo de procura após o trauma e o grau de cooperação da criança diante o tratamento sugerido. O tratamento não envolve apenas a intervenção de urgência, o paciente deve passar por um acompanhamento e controle clínico radiográfico depois de 30, 60 e 120 dias e anualmente até a Esfoliação do dente decíduo. Pôde-se verificar que foi restabelecida a saúde da criança no aspecto estético e funcional.

Influência da progesterona injetável na taxa de prenhez e perda gestacional de fêmeas nelore de distintas categorias reprodutivas submetidas a inseminação artificial em tempo fixo / Influence of injectable progesterone on the pregnancy rate and gestational loss of Nellore females of different reproductive categories undergoing fixed-time artificial insemination

Progesterone (P4) is essential for embryonic development and maintenance of pregnancy when deficiency causes early embryonic loss. In this study, we investigated the ability of hormonal supplementation to improve the fertility of Nellore females subjected to fixed-time artificial insemination (IATF) protocols. Here, we evaluated the effect of long-acting injectable progesterone (iP4) supplementation in the D4 after IATF on pregnancy rate and pregnancy loss in Nellore females (Bos taurus indicus) from different reproductive categories in Western Amazonia. Eight hundred thirteen Nellore females from 5 farms were selected and distributed into 2 groups: control [GC; administration of 0.5 mL of 0.9% saline solution, intramuscularly - IM] (n = 407) and a group that received injectable progesterone (iP4) that was long-acting [GiP4; administration of 0.5 mL of iP4, 300 mg, via IM four days after IATF] (n = 406). Each group contained 3 subgroups: heifers, primiparous cows, and multiparous cows. Of the 407 animals in the CG, 103 were heifers, 107 primiparous, and 197 multiparous. Of the 406 animals in the GiP4 group, there were 101 heifers, 107 primiparous, and 198 multiparous. On a random day of the estrous cycle (D0), an intravaginal device containing 1 g of P4 and 2 mg of estradiol benzoate (BE) was inserted by intramuscular injection. On D8, the P4 device was removed and 150 µg of D-cloprostenol (PGF2α), 300 IU eCG, and 1 mg BE were administered IM. Cows were inseminated at D10, 48-52 h after procedure on D8. Pregnancy diagnosis was made between 35 and 40 days after insemination through ultrasound examination. Between 80 and 90 days after insemination, a new ultrasound examination was performed to assess early pregnancy loss. The data were processed using the SAS 9.2. The conception rate, pregnancy loss, and final conception rate were analyzed using PROC GLIMMIX according to groups (CG and GiP4), categories (heifers, primiparous and multiparous), and their interactions as variables. The differences in the means of least squares were adjusted using the Tukey­Kramer method. Statistical significance was defined as P < 0.05. The general conception rate was 46% (375/816). Regardless of the animal class, GiP4 animals (51.97%) had higher conception rates (P < 0.05) than CG (40.29%). In the subgroups (heifers, primiparous and multiparous cows), there was a difference (P < 0.05) between animals treated with iP4 (52.48%, 57.94%, and 48.48%, respectively) and those who were not (39.81%, 41.12%, and 40.10%, respectively). Gestational losses, regardless of the animal class, were higher in females in the CG (7.93%) [P < 0.05] compared to those in the GiP4 group (2.84%). Regardless of treatment with iP4, the percentage of gestational loss in heifers was significantly higher (10.64%) than that in primiparous and multiparous cows (3.77% and 2.86%, respectively). The final conception rates were higher in animals that received long-acting iP4, which increased the final pregnancy in all parity categories. In the present study, the use of iP4 increased the pregnancy rate in Nellore females, regardless of the category. Although there has been no consensus on the use of iP4, there is an agreement that increases in the pregnancy rate are related to the moment of exogenous P4 application. In addition to influencing the pregnancy rate, reduction in pregnancy losses is also attributed to iP4 treatment, a fact demonstrated in the present study, where animals treated with iP4 had a lower pregnancy loss rate than normally occurs in beef cattle. Supplementation with long-acting iP4 increased the pregnancy rate at D35-40, reduced pregnancy losses, and increased the conception rate on D80-90 days in Nellore females reared in the Western Amazon, regardless of the animal category.(AU)

Consequences of eight consecutive applications of equine chorionic gonadotropin on ovarian follicle development and ovulation in bos indicus cows / Consequências do uso consecutivo de oito doses de gonadotrofina coriônica equina no desenvolvimento folicular e ovulação de vacas bos indicus

ABSTRACT: The equine chorionic gonadotropin (eCG) is a glycoprotein produced in mare endometrial calices. In bovine, it is used in estrus synchronization protocols. However, studies have shown that it is potentially immunogenic and its effect can decrease after repetitive use. This study aimed to evaluate antral follicle dynamics, corpus luteum (CL) and ovulation rate in bos indicus cows submitted to an estrus synchronization protocol in association with eCG for eight times consecutively. Ten cyclical, multiparous, and pasture raised beef cows were divided into two groups: control group (n=5) and eCG group (n=5). In 30 day interval, all animals were synchronized with the same estrogen/progesterone based protocol, totalizing 8 re-synchronizations. Cows in the treatment group received 300IU eCG 48 hours prior to the presumable ovulation. Ultrassound examinations were performed on Day 4 of the protocol (approximately 1.5 days after follicle recruitment) to count antral follicles, on Day 10, to count antral follicles and to measure size of the largest follicle and on Day 18 to measure the diameter of the CL. No difference (P>0.05) between follicular growth and size of the pre-ovulatory follicle was reported between groups. Cows treated with eCG had a larger (P<0.05) CL and increased (P<0.05) ovulation rate (18mm and 92%, respectively) when compared with control group (14.1mm and 80%, respectively). Furthermore, consecutive treatments did not affect CL nor ovulation rates. In conclusion, eCG treatment increased CL size and ovulation rate even after 8 consecutive treatments.

RESUMO: A gonadotrofina coriónica equina (ECG) é uma glicoproteína produzida nos cálices endometriais da égua. Em bovinos, é utilizada em protocolos de sincronização do estro. Estudos têm mostrado que ela é potencialmente imunogênica e seu efeito pode diminuir depois de utilização repetida. O objetivo do presente trabalho foi avaliar a dinâmica folicular, o diâmetro do corpo lúteo (CL) e taxa de ovulação em vacas bos indicus submetidas a um protocolo de sincronização estral com eCG por oito vezes. Dez vacas de corte, cíclicas, multíparas e solteiras foram divididas em dois grupos: grupo controle (n=5) e grupo eCG (n=5). Em um intervalo de 30 dias, os animais foram sincronizados com um protocolo de estrógeno/progesterona, totalizando 8 re-sincronizações. Os animais do grupo tratamento receberam 300UI eCG 48 horas antes da provável ovulação. Exames ultrasonográficos foram realizados no dia 4 do protocolo (aproximadamente 1,5 dias após o recrutamento folícular), para contar folículos antrais, no dia 10, contar folículos antrais e medir o tamanho do maior folículo e, no dia 18, para medir o diâmetro do CL. Não foi encontrada diferença (P>0,05) entre folículos no dia 4 ou 10. Vacas tratadas com eCG tinham um maior (P<0.05) CL e elevada (P<0.05) taxa de ovulação (18mm e 92%, respectivamente) quando comparadas ao grupo controle (14,1mm e 80%, respectivamente). Além disso, tratamentos consecutivos não afetaram o CL nem as taxas de ovulação. Em conclusão, o tratamento com eCG aumentou o tamanho do CL e taxa de ovulação, mesmo depois de 8 tratamentos consecutivos.
