De acordo com o summary in this paper, the healing of extraction wound was studied in the presence of foreign bodies (fragments of silver malagam and of zine oxide eugenol impression paste). Clinically, a little delay in the gingival union was noted, mainly in the sockets with fragments of silver amalgam. The histological observation on the 3rd, 11nd, and 40th post-extraction days revelaed that both materials used in the experiments prduced foreign body reaction only in the early stage of the socket healing. Histologically, the results showed that silver amalgam fragments produced a longer delay in the helaing process than zine oxide-eugenol paste fragments, but in both cases, healing was reached."

De acordo com o summary: "A follow-up evaluation of socket healing in the presence of retained root caused by incomplete exodontia was carried out. Depending on the conditions, the remmant root may or may not be left in the alveolus. The small fragment of vital dental root almost never provokes any complication, but it is encapsulated by osseus and cementum neoformations. Its extraction is recommended only if it involved by any pathological disturbance. When the fracture occurs at the superficial leval, the salivary infiltration leads to a constant contamination, preventing the extraction wound from completely healing."

De acordo com o abstract: "Small bone from a dog fixed in formaldehide from onte to four weeks, were used as homoimplants in the left post-extraction sockets of dogs, and the right ones were allowed to heal as ungrafted controls. The animals were sacrificed 5, 11, 22 and 60 days after implantation. No obvious differences were discovered either clinically or in X-rays between the repair of the controls sockets and the experimental ones. However, appreciable histological differences could be noted. the presence of the implant disturbed and retarded both the organization of the granulation tissue abd the process of the intra-alveolar ossification. The attempt to use homogenous bone implants that had been preserved in formaldehyde in order to stimulate osteogenesis in the host produced unsatisfactory results, for it retarded the process of the post-extraction alveolar repair."

"O processo de todo processo inflamatório equivale ao acionamento de outro fenômeno biológico, cuja finalidade maior consiste na restauração normal da continuidade anatômica do órgão ou tecido agredido. Sempre que ocorrer perda de substânica, por trauma 9acidental ou cirúrgico) ou por necrose, de qualquer natureza, ocorrerá um mecanismo biológico de restauração, o qual se preocessa segundo dois aspectos totalmente diversos, ou seja, a regeneração e a reparação.
A regeneração é um fenômeno pelo qual a perda tecidual é restituída pela proliferação de células semelhantes às destruídas. Ocorre principalmente em tecidos especializados como os parênquimas...."

"Small bone sticks from a dog, fixed in formaldehyde from 1 to 4 weeks, were used as homimplants in the left postextraction sockets of dogs, and the right sockets were allowed to heal as ungrafted controls. The animals were killed 5, 11, 22, and 60 days after implantations. No obvious differences were discovered, either clinically or radiographically, between the repair of the control sockets and that of experimental sockets. However, appreciable histologic differences could be noted. The presence of the implant disturbed and retarded both the organization of the granulation tissue and the process of the alveolar ossification. The attempt to use homogenous bone implants taht had been preserved in formaldehyde in order to stimulate osteogenesis in the host produced unsatisfactoey results, since it retarded the process of postextraction alveolar repair."

Ao presente estudo froam aplicados, por via sistêmica, o acetato de metilprednisolona, isoladamente, e associado ao Acetato de 4-clorotestosterona, em cães, portadores de feirdas de extrações dentárias. Observou-se clínica e radiograficamente, que o acetato de metil-prednisolona retardou, de forma sensível, a cura alveolar; o acetato de 4-clorotestosterona, quando associado ao Acetatto de metil-predonisolona, neutralizou satisfatoriamente, seus efeitos indesejáveis."

De acordo com o resumo: "Serão apresentados neste trabalho, os resultados clínicos, radiográficos e histológicos de reimplantes dentais efetuados experimentalmente em cães. Três grupos distintos de 10 animais foram utilizados. No grupo I, os dois incisivos laterais superiores de ambos os lados foram extraídos. Os incisivos laterais direitos foram conservados em solução fisiológica, previamente ao reimplante, em vários tempos diferentes, pré-determinados, e serviam como controle. Os incisivos laterais esquerdos foram conservados em formol a 10% nos mesmos tempos e reimplantados. No grupo I e II, procedeu-se de forma idêntica utilizando-se soluções de fluoreto de sódio e estanhoso em determinadas concentrações. O objetivo destes trabalhos é o de verificar se tais soluções empregadas tem propriedade de inibir ou pelo menos de retardar o processo de reabsoção redicular após reimplantação dentária, que é o fator de insucesso desta intervenção."
