Tissue Levels of Matrix Metalloproteinases in Pulps and Periapical Lesions
Journal of Endodontics, 2002The purpose of this study was to evaluate the tissue levels of matrix metalloproteinase (MMP)-1, -2, -3 and their distributions in inflamed human dental pulps and periapical lesions. Samples were subjected to enzyme-linked immunosorbent assay and/or immunohistochemistry by using specific antibodies to MMP-1, -2, and -3.

Sodium hypochlorite injection into periapical tissues.
Dental update, 1995The following case report demonstrates the tissue changes that may occur when sodium hypochlorite, an irrigant used for debridement of the root canal system, is inadvertently injected into periapical tissues.

Periapical tissue response to two calcium hydroxide-containing endodontic sealers
Journal of Endodontics, 1990One-hundred twenty root canals of dog teeth were cleaned, shaped, and obturated with gutta-percha and sealers using a lateral condensation technique. The sealers used were Sealapex, CRCS, and zinc oxide-eugenol. The animals were killed after 30 or 180 days and the specimens were examined histologically.

Pulpal and periapical tissue response to butyl 2-cyanoacrylate
Oral Surgery, Oral Medicine, Oral Pathology, 1969Abstract A series of experiments was conducted with the use of butyl 2-cyanoacrylate and cavity varnish on traumatically exposed pulps in the albino rat. Histologic comparisons were made between three groups of animals, showing that the sealing effect of the cavity varnish was dissipated in between 1 and 7 days.

Endothelial Cell and Stromal Antigens in Human Periapical Granulation Tissue
Journal of Endodontics, 2000Periapical granulation tissue consists of vasculature of varying sizes and types, infiltrating cells, and other stromal elements. We examined the differential expression of endothelial and stroma antigens in this tissue to determine their tissue distribution in order to obtain hints on their functions. Some of the antigens examined were present only in

Influence on periapical tissues of indigenous oral bacteria and necrotic pulp tissue in monkeys
European Journal of Oral Sciences, 1981Abstract – In nine monkeys (Macaca Fascicularis) the pulps of 78 teeth were aseptically necrotized. Twenty‐six of the pulp chambers were kept bacteria‐free by sealing, while 52 were infected by the indigenous oral flora. The results were recorded clinically, radiographically and microbiologically at the begining of the experiment and after 6–7 months.

PERİAPİKAL DOKU REAKSİYONLARI-PERIAPICAL TISSUE REACTIONS
2013ÖZETBu makalede periapikal iltihabın oluşmasında ilgili faktörler olarak, pulpa iltihabı, endodontik işlemler, kök kanalı dolgu maddeleri, gözden geçirilmiştir. Ayrıca periodontal hastalıkların, pulpa ve periapikal dokular üzerindeki etkisi konusundaki tartışmalarda bu makalede incelenmiştir.

Influence of combinations of oral bacteria on periapical tissues of monkeys
European Journal of Oral Sciences, 1982Abstract – The present study deals with the ability of 11 bacterial strains, in various combinations, to induce periapical reactions. The indigenous oral bacteria were originally isolated from an experimental apical periodontitis in monkey. Eight of the strains were a complete collection isolated from one root canal.

Infections and tumors arising in and from the periapical tissues
Oral Surgery, Oral Medicine, Oral Pathology, 1957Summary o 1. The data from 505 specimens obtained from 2,735 consecutive surgical cases have been presented. 2. The radiographic appearance and histopathology of the various lesions arising from the periapical tissue have been discussed. 3. The frequency of significant pathology in periapical involvement has been presented and discussed. 4.

[Evaluation of the periapical tissue lesions by roentgenogram].
Stomatologia, 1991Most of the periapical tissue lesions appear as radiolucent areas in a reontgenogram. However, several lesions of pulpal and periodontal origin as well as lesions caused by benign or malignant tumors appear in the roentgenogram as radiopaque areas.
