2	Efeitos clínicos periodontais da expansão rápida da maxila em incisivos centrais superiores / Periodontal clinical effects of rapid maxillary expansion on central upper incisors Ortiz, Samira Falleiros 16 October 2018 (has links) Introdução: O arco dentário superior de pacientes com mordida cruzada posterior normalmente apresenta-se atrésico e a expansão rápida da maxila é indicada para esses casos durante a dentadura mista promovendo abertura da sutura palatina mediana e incrementos transversais na região posterior e anterior do arco dentário. Objetivo: O objetivo deste trabalho consistiu em avaliar os efeitos da expansão rápida da maxila, utilizando o disjuntor com cobertura em acrílico, por meio do acompanhamento clínico nos incisivos superiores. Material e Método: A amostra do estudo foi composta por 21 indivíduos com mordida cruzada posterior, uni (2) ou bilaterais (21), e atresia do arco dentário superior. O procedimento de expansão rápida da maxila foi realizado na dentadura mista tardia, por meio do aparelho de expansão com cobertura oclusal em acrílico. Foram analisados os parâmetros clínicos obtidos mensalmente até o final do tratamento: o índice de placa dental visível (IPV), índice sangramento gengival (ISG), profundidade de sondagem (PS), nível clínico de inserção (NIC) e índice de sangramento á sondagem (SS). As medidas pré e pós-tratamento foram submetidas ao teste t pareado (p<0,05). Resultados: Não foram observadas diferenças estatisticamente significantes entre o tempo inicial e final para as variáveis ISG, ISS e PS, porém houve uma diminuição significativa para PV durante os períodos de 30, 60 e 150 dias e 180 dias. Conclusão: Alguns parâmetros clínicos periodontais (índice de profundidade á sondagem e índice de placa visível) diminuíram ou foram similares antes e depois do tratamento com ERM. Porém, o índice de sangramento á sondagem e o índice de sangramento gengival finais foram estatisticamente maiores que no início do tratamento / Introduction: The upper dental arch of patients with posterior crossbite is usually atresic and rapid maxillary expansion is indicated for these cases during the mixed dentition, promoting the opening of the medial palatine suture and transverse increments in the posterior and earlier region of the dental arch. Objective: The purpose of this study was to evaluate the effects of rapid maxillary expansion using the acrylic cover breaker, through clinical in the upper incisors. Material and Method: The study sample consisted of 21 individuals with posterior crossbite, uni (2) or bilateral (19) and upper dental arch atresia. The rapid maxillary expansion procedure was performed in the late mixed dentition using the expansion apparatus with acrylic occlusal cover. Were analyzed the clinical parameters obtained monthly until the end of the treatment: visible dental plaque index (VDP), gingival bleeding index (GB), probing depth (PD), clinical insertion level (CIL) and bleeding probing index SU). Pre-and posttreatment measurements were submitted to paired t-test (p<0.05). Results: There were no statistically significant differences between the initial and final time for GB, PD and SU, but there was a significant decrease for VDP during the 30, 60 and 150 day periods. Conclusion: Some periodontal clinical parameters (depth to depth index and visible plaque index) decreased or were similar before and after MRE treatment. However, the final bleeding index and gingival bleeding index were statistically higher than at the beginning of treatment Disjuntor de McNamara Incisivos superiores McNamara circuit breaker Orthodontics Ortodontia Periodontia Periodontics Upper incisors
3	Efeitos da expansão rápida da maxila em dentes e periodonto / Effects of rapid jaw expansion on teeth and periodontium Bottacin, Fabio Santos 01 June 2017 (has links) Introdução: O arco dentário superior de pacientes com mordida cruzada posterior normalmente apresenta-se atrésico e a expansão rápida da maxila é indicada para esses casos durante a dentadura mista promovendo abertura da sutura palatina mediana e incrementos transversais na região posterior do arco dentário. Objetivo: O objetivo deste trabalho consistiu em avaliar os efeitos da expansão rápida da maxila, utilizando o disjuntor com cobertura em acrílico, por meio do acompanhamento clínico e radiográfico. Material e Método: A amostra do estudo foi composta por 21 pacientes com mordida cruzada posterior, uni ou bilaterais e atresia do arco dentário superior. O procedimento de expansão rápida da maxila foi realizado na dentadura mista tardia, por meio do aparelho de expansão com cobertura oclusal em acrílico. Foram realizados exames de feixe cônico antes da instalação do aparelho e 06 meses após a instalação do disjuntor McNamara, na ocasião da remoção do aparelho. Nas imagens de tomografia computadorizada, as mensurações foram realizadas por meio do software On Demand 3D (Versão 1.0, Cybermed Inc., Seul, Coreia do Sul). Nas imagens de tomografia computadorizada foram analisadas a espessura das tábuas ósseas vestibular e lingual, o nível da crista óssea vestibular dos primeiros molares permanentes, a largura do palato duro, a distância transversa entre os primeiros molares superiores. Os parâmetros clínicos foram obtidos mensalmente até o final do tratamento: o índice de placa dental visível (IPV), índice sangramento gengival (ISG), profundidade de sondagem (PS), nível clínico de inserção (NIC) e índice de sangramento à sondagem (SS). As medidas pré e pós-tratamento foram submetidas ao teste t pareado (p<0,05). Resultados: Não foram observadas diferenças estatisticamente significantes entre o tempo inicial e final para as variáveis IPV, ISG, ISS, PS E NIC, porém houve um aumento significativo para PS e NIC durante os períodos de 30, 60 e 150 dias. Os resultados das medidas realizadas por meio da TCFC não mostraram diferenças estatisticamente significantes entre os tempos para a altura da crista óssea vestibular. A espessura da tábua óssea vestibular diminuiu nos molares permanentes e deciduos, sendo essa diminuição significativa apenas nos molares permanentes (p<0,05), enquanto que no lado palatino aumentou significativamente (p<0,001) em todos os dentes analisados. Não houve redução da crista óssea vestibular. À distância bi-molar mostrou um aumento significativo (p<0,001) tanto na região cervical quanto na região apical. O mesmo aumento significativo (p<0,001) foi verificado para a largura do palato. Conclusão: Os resultados dos parâmetros clínicos e das medidas realizadas por meio da tomografia computadorizada permitiu constatar o efeito ortopédico do disjuntor com acrílico na oclusal dos dentes na expansão rápida da maxila. As alterações observadas não sugerem danos significativos aos dentes e nas estruturas periodontais avaliadas. / Introduction: The upper dental arch of patients with posterior crossbite is usually atresic and rapid maxillary expansion is indicated for these cases during the mixed dentition, promoting the opening of the medial palatine suture and transverse increments in the posterior region of the dental arch. Objective: The purpose of this study was to evaluate the effects of rapid maxillary expansion using the acrylic cover breaker, through clinical and radiographic monitoring. Material and Method: The study sample consisted of 21 patients with posterior crossbite, uni or bilateral and upper dental arch atresia. The rapid maxillary expansion procedure was performed in the late mixed dentition using the expansion apparatus with acrylic occlusal cover. Cone beam tests were performed prior to appliance installation and 06 months after the McNamara circuit breaker was installed at the time of removal. Computed tomography images were measured using On Demand 3D software (Version 1.0, Cybermed Inc., Seoul, South Korea). Computed tomography images were analyzed for the thickness of the buccal and lingual bone plates, the level of the buccal bone crest of the first permanent molars, the width of the hard palate, the transverse distance between the first maxillary first molars. Clinical parameters were obtained monthly until the end of the treatment: visible dental plaque index (IPV), gingival bleeding index (ISG), probing depth (PS), clinical insertion level (NIC) and bleeding probing index SS). Pre- and posttreatment measurements were submitted to paired t-test (p <0.05). Results: There were no statistically significant differences between the initial and final time for IPV, ISG, ISS, PS and NIC, but there was a significant increase for PS and CIN during the 30, 60 and 150 day periods. The results of the measurements made through the CBCT did not show statistically significant differences between the times for the height of the buccal bone crest. The thickness of the buccal bone plate decreased in the permanent and deciduous molars, which was only significant in the permanent molars (p <0.05), whereas on the palatine side it increased significantly (p <0.001) in all teeth analyzed. There was no reduction of the buccal bone crest. At the bi-molar distance showed a significant increase (p <0.001) in both the cervical region and the apical region. The same significant increase (p <0.001) was found for the width of the palate. Conclusion: The results of the clinical parameters and the measurements made by means of the computerized tomography allowed to verify the orthopedic effect of the acrylic breaker in the occlusal of the teeth in the rapid expansion of the maxilla. The observed changes do not suggest significant damage to the teeth and to the periodontal structures evaluated.

5	A Hawkish Dove? Robert S. McNamara in the Cuban Missile Crisis and the Vietnam War, 1962-1968 Unknown Date (has links) Robert S. McNamara served as U.S. Secretary of Defense (SOD) for Presidents John Kennedy and Lyndon Johnson. McNamara participated in the Cuban Missile Crisis negotiations in 1961 and became a key formulator of Vietnam policy. This thesis challenges scholarship that characterizes McNamara as a fierce hawk who relentlessly executed military escalation in Vietnam. By drawing parallels between McNamara’s role in the Cuban Missile Crisis and the Vietnam War, and by exploring how McNamara’s concept of loyalty to the presidency influenced his decisions, this thesis argues that the SOD was willing to escalate the situation militarily as a form of political communication with the adversary. To McNamara, military pressure was a means to create avenues for diplomacy. McNamara became increasingly uncomfortable – and ultimately resigned in 1968 - when the Johnson administration pursued military escalation without an organized campaign towards negotiations. He was therefore not as hawkish as other scholars have claimed. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection McNamara, Robert S, 1916-2009 Cuban Missile Crisis, 1962 Vietnam War, 1961-1975

7	The Limits of Fire Support: American Finances and Firepower Restraint during the Vietnam War Hawkins, John Michael 16 December 2013 (has links) Excessive unobserved firepower expenditures by Allied forces during the Vietnam War defied the traditional counterinsurgency principle that population protection should be valued more than destruction of the enemy. Many historians have pointed to this discontinuity in their arguments, but none have examined the available firepower records in detail. This study compiles and analyzes available, artillery-related U.S. and Allied archival records to test historical assertions about the balance between conventional and counterinsurgent military strategy as it changed over time. It finds that, between 1965 and 1970, the commanders of the U.S. Military Assistance Command, Vietnam (MACV), Generals William Westmoreland and Creighton Abrams, shared significant continuity of strategic and tactical thought. Both commanders tolerated U.S. Army, Marine Corps, and Allied unobserved firepower at levels inappropriate for counterinsurgency and both reduced Army harassment and interdiction fire (H&I) as a response to increasing budgetary pressure. Before 1968, the Army expended nearly 40 percent of artillery ammunition as H&I – a form of unobserved fire that sought merely to hinder enemy movement and to lower enemy morale, rather than to inflict any appreciable enemy casualties. To save money, Westmoreland reduced H&I, or “interdiction” after a semantic name change in February 1968, to just over 29 percent of ammunition expended in July 1968, the first full month of Abrams’ command. Abrams likewise pursued dollar savings with his “Five-by-Five Plan” of August 1968 that reduced Army artillery interdiction expenditures to nearly ten percent of ammunition by January 1969. Yet Abrams allowed Army interdiction to stabilize near this level until early 1970, when recurring financial pressure prompted him to virtually eliminate the practice. Meanwhile, Marines fired H&I at historically high rates into the final months of 1970 and Australian “Harassing Fire” surpassed Army and Marine Corps totals during the same period. South Vietnamese artillery also fired high rates of H&I, but Filipino and Thai artillery eschewed H&I in quiet areas of operation and Republic of Korea [ROK] forces abandoned H&I in late 1968 as a direct response to MACV’s budgetary pressure. Financial pressure, rather than strategic change, drove MACV’s unobserved firepower reductions during the Vietnam War. 11th marines 12th marines abrams air force allied american way of war ammunition army artillery attrition arvn australian b-52 birtle budget cap cea classical clausewitz clifford coled-v collins communist congress constraints conventional counter-battery counterinsurgency dollar expenditures filipino finances fire support firepower five-by-five free world military fwmaf h&i haines harold harrassment hunt hybrid interdiction johnson kalergis komer korean krepinevich laird leonard taylor lewy lyndon macv marines mcnamara mekong nagl new zealand nixon nva observed operations philippine preemptive preparatory resor restraint riverine rok savings sensors sorley south vietnamese strategy summers tactics thai third country trinity unconventional unobserved usarv van fleet viet cong vietnam westmoreland wheeler wise men
