O uso do bisturi eletrônico como selador do ápice radicular, após apicectomia : estudo in vitro /Wagner, João Carlos Birnfeld. January 2002 (has links)
Orientador: Antonio Cesar Perri de Carvalho / Banca: Márcio Giampietro Sanches / Banca: Paulo Villela Santos Júnior / Banca: Nilza Pereira da Costa / Banca: João Gualberto de Cerqueira Luz / Resumo: Este trabalho objetivou avaliar a ação do bisturi eletrônico sobre o ápice de dentes monorradiculares superiores, incisivos e caninos, extraídos de humanos, todos com rizogênese completa. Utilizou-se, como solução evidenciadora, o azul de metileno a 2%, em estufa biológica a 37ºC por sete (7) dias. Para tanto, foram usados 48 dentes, divididos em 6 grupos. No primeiro grupo, Grupo Controle, não foi usado o bisturi eletrônico no ápice. Todos os dentes foram apicetomizados a 2mm do ápice. Cinco grupos foram impermeabilizados sem fixação, após o uso do bisturi eletrônico no ápice, e colocados em solução evidenciadora. No outro grupo, a impermeabilização foi fixada em estufa biológica a 37ºC, por 24 horas. A análise dos resultados mostrou diferentes graus de infiltração do corante, evidenciando claramente as alterações na luz do ápice dentário, diretamente proporcional ao tempo de ação do bisturi eletrônico. / Abstract: The aim of this paper is to evaluate the action of the electrocautery in the radicular apex of extacted humans superiors incisors and canines, all of them with completed rizogenesis. It was used 2% blue methylate as marker, in biological stove at 37ºC during 7 (seven) days. The experiment included 48 teeth, divided in 6 groups. At the control group the electrocautery wasn't used. All the teeth were apicoectomized 2 mm from the apex. Five groups were made impermeable without fixation, after the used of electrocautery in the apex and putted in the marker solution. In the other group, the teeth with the impermeable were fixed in the biological stove for 24 hours. The analysis of the results showed different levels of intiltration of the marker, making clear the alterations in the light of the dental apex, straightly proportional at the period of time that the electrocautery was used. / Doutor

The effects of apical modification on the vitality of replanted permanent monkey teethWalsh, John Senan, 1951- January 1977 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / A study was conducted on the effects in a rhesus monkey of increasing
the surface area of pulpal tissue available for revascularisation
and regeneration of nerves after replantation of permanent teeth. Four
teeth were replanted and used for controls, including two with incomplete
apical development. Twelve teeth with completed apical development
were replanted immediately after apical modification to increase
the surface area of exposed pulp. The technique consisted of creating
a facial and lingual groove in the apical region and exposing additional
pulpal tissue. Radiographs were taken periodically and the replanted
teeth were stable during the study period. The monkey was sacrificed
after 93 days.
The first hypothesis, that the apically modified teeth would sustain
a healthy periodontium clinically for a period of ninety days, was
disproved.
Histological sections of the teeth and their supporting tissues
showed varying amounts of root resorption and ankylosis. All of the
apically modified teeth showed pulp necrosis, while three of the four
control teeth had reestablished blood and vascular supplies and appeared
vital. Ingrowth of granulation tissue was seen in the replanted teeth
with pulp necrosis including one control tooth which had failed to revascularize.
The second hypothesis, that the apically modified teeth would demonstrate
significantly more apical revascularisation and nerve regeneration
than the control teeth, was also disproved.
In conclusion, the apical modification technique as performed to
increase the area available for regeneration of nerves and vessels was
not a success. As expected, however, immediate replantation of avulsed
teeth resulted in reestablishment of periodontal membrane attachments.
