Estudo topográfico da dor de origem dentária / Study of refered pain of dental origin

Milene Camargo Regatão 26 March 2010 (has links)
A maioria dos pacientes que têm dor de origem dentária pulpar ou periapical tem dor referida, e algumas características da dor parecem influenciar este fenômeno. Por meio do preenchimento de fichas clínicas, com informações sobre as características da dor, investigamos, em 60 voluntários, a distribuição topográfica de áreas de dor referida de origem dentária. Por meio de métodos psicofísicos, comparamos a resolução espacial da dor com a resolução espacial de outras modalidades somestésicas (mecânica e térmica). Nossos resultados indicam que a intensidade da dor favorece o fenômeno da dor referida e interfere na sua dispersão topográfica. Dentes algógenos com polpa viva influenciam um maior espalhamento da dor. A organização hodológica do núcleo espinal do trigêmeo e mecanismos fisiológicos de integração neural podem explicar de maneira satisfatória várias características da dor referida. Além disso, observamos que a resolução espacial na localização da dor é maior que a resolução espacial da localização de outros estímulos somestésicos nos elementos dentários. / The majority of patients who suffer from toothache report referred pain to other sites in the head and neck. Thus, the aim of this study was to investigate the clinical and psychophysical characteristics of referred pain in the orofacial region and how factors such as intensity, duration and nature of odontogenic pain might modulate them. We employed psychophysical and clinical methods to correlate pain perception with the anatomy and physiology of the trigeminal system. Sixty patients reporting primary toothache were investigated as to the clinical and psychophysical aspects of their pains symptoms and signals (intensity, duration, location and state of the pulp inflammatory process). Pain intensity and state of irreversible pulp inflammation were found to significantly affect facilitate the incidence of referred pain and its spread across vertical laminations. Considering these results, we proposed a physiological model based on both neuronal integration (spatial and temporal summation) and the topographic organization of the trigeminal system, which is able to explain the observed characteristics of referred dental pain.

A produ??o das perdas dent?rias: narrativas de usu?rios do SUS

No. of bitstreams: 1 JussaraAD.pdf: 601035 bytes, checksum: cffe252603743caec8889a83b0645aab (MD5) Previous issue date: 2008-08-27 / For a complete comprehension of the effect of tooth loss is necessary to listen to the patients that have it. This study, of qualitative approach, investigate, in the dental history of users of SUS, listening to his/her experiences with the services of dental care, the reason that lead his/her to dental lost and the repercussion of this in his/her life. The collect of data was made by narrative interview, obeying to a pre-defined schema. The subjects interviewed were six (three of urban zone and three of rural zone), all of them were users of Family Health Units. The criterions of inclusion were the followings: the presence of tooth lost (total lost in both dental arch or in one of them, or partial lost in at least six elements in one of the arches); age between 25 and 59; male or female; to live in municipal district of S?o Tom?/RN or Natal/RN. Based on previous interviews was elaborated the odontological history of each patient. Such narratives, systemized in odontological history, were analyzed taking as base the studies of Souza71 and the proposal of Schutze, suggested for Jovchelovitch, Bauer34. The results show that toothache was the main reason for the search of odontological care. The patients confront the ache with home-made medicaments, allopathic ones, and searching for dental care. The searching for exodontics was stimulated for geographic access difficulties or for repressed demand, which as a result produced the aggravation of the lesions and the discredit in restoration s treatment. The self-care practice of tooth-brush with ju? or toothpaste and the controlled ingestion of sugar was not sufficient to avoid dental lost. Guilty sentiments were identified in relation with lack of care with teeth. The acceptance of dental lost as a natural factor is an important motivation in lack of pain and in the belief that it was a simple part of life in old age. Life with dental prosthesis makes clear the difference between which was natural and which was unnatural, and difficulties with the prosthesis appeared. The limitation of the prosthesis in its functional aspect can be compensated by esthetic restitution, making possible smiling expression. Starting with this study and considering the high number of dental lost, mainly in low-rent population, which live with toothless limitations or bad-quality prosthesis which do not rehabilitate adequately, we suggested the realization of qualitative researches which include, also, another actors in heath care services such as professionals and administrators / A compreens?o ampliada dos efeitos da perda dent?ria exige escuta dos sujeitos que a experimenta. Este estudo, de abordagem qualitativa, investigou, na hist?ria odontol?gica de usu?rios do SUS, a partir do relato de suas experi?ncias com os servi?os de sa?de bucal, os motivos que os levaram ? perda dent?ria e as repercuss?es desta em suas vidas. A coleta de dados foi realizada por meio da t?cnica de entrevista narrativa, adaptada, utilizando-se roteiro semi-estruturado. Os sujeitos entrevistados, num total de seis (tr?s da zona urbana e tr?s da zona rural), foram usu?rios de Unidades de Sa?de da Fam?lia. Consideraram-se os seguintes crit?rios de inclus?o: presen?a de desdentamento (perda total em ambas as arcadas, ou em uma delas, ou perda parcial a partir de seis elementos em uma das arcadas); idade ente 25 e 59 anos; qualquer g?nero; ser morador dos munic?pios de S?o Tom?/RN e Natal/RN. A partir do conte?do das entrevistas foi elaborada a hist?ria odontol?gica de cada entrevistado. Tais narrativas, sistematizadas em hist?rias odontol?gicas, foram analisadas com base em estudo de Souza e na proposta de Sch?tze, sugerida por Jovchelovitch, Bauer. Os resultados indicaram que a experi?ncia de dor foi o principal motivo pela procura por assist?ncia odontol?gica. As formas de enfrentamento da dor deram-se pelo uso de medica??es caseiras e alop?ticas e pela busca do servi?o de sa?de. A procura pela exodontia foi favorecida pela dificuldade de acesso geogr?fico ou pela grande demanda reprimida, o que produziu agravamento das les?es e descr?dito na efic?cia do tratamento restaurador. A pr?tica do autocuidado atrav?s da escova??o com ju? ou creme dental e o controle do consumo de a??car n?o foram suficientes para evitar a perda dent?ria. Foram identificados sentimentos de culpa relacionados ? falta de cuidado. A aceita??o da perda dent?ria como natural teve forte rela??o com a garantia de aus?ncia de dor e a cren?a de fazer parte do processo de envelhecimento. A conviv?ncia das pessoas com a pr?tese dent?ria mostrou a diferen?a entre o que era natural e o que era artificial e, a partir da?, foram aparecendo situa??es de estranhamento com a pr?tese. A limita??o da pr?tese quanto ao aspecto funcional pode ser compensada pela restitui??o da est?tica, ao possibilitar a express?o do sorriso. A partir deste estudo e considerando o elevado n?mero de perdas dent?rias, especialmente em popula??es de menor poder aquisitivo, que convivem com limita??es pr?prias da condi??o de desdentado e ou com pr?teses de m? qualidade que n?o reabilitam, adequadamente, sugere-se a realiza??o de pesquisas de abordagem qualitativa que inclua, tamb?m, outros atores implicados na produ??o de cuidados e servi?os de sa?de profissionais e gestores
