Inflammation and infection of the pulp and periapical tissues: A synthesis

Oral Surgery, Oral Medicine, Oral Pathology, 1972
Abstract This paper is a compilation, correlation, and summarization of the views of participants in the Workshop on the Biologic Basis of Modern Endodontic Practice. It represents a synthesis of three input sources: the position and review papers presented at the Workshop, the consensus of the Workshop participants, and the particular expertise of ...

Periapical tissue reaction to root fillings with Sealapex

International Endodontic Journal, 1990
Summary. The histological response of periapical tissues to root canal fillings with Sealapex, pure calcium hydroxide and gutta‐percha points was studied in dogs' teeth. After putpal extirpation the root canals were enlarged, irrigated and dried. Teeth in the first group were filled with gutta‐percha points alone, those in the second group were filled

Experimentally Induced Alterations in Periapical Tissues of the Cat

Journal of Dental Research, 1980
Ten cats were immunized with subcutaneous injections of keyhole limpet hemocyanin (KLH). After it was determined that the experimental animals had developed circulating antibodies to KLH, challenge doses of KLH were administered via the root canal system. The radiographic and histologic findings suggest that antigen-antibody complex reactions can occur

Tissue pH of developing periapical lesions in dogs

Journal of Endodontics, 1983
pH readings were taken at various time intervals of the periapical tissues of beagles' teeth with open apices. The teeth had been infected with a virulent strain of Streptococcus faecalis . After inoculation, some teeth were treated with an acid paste, others with a basic paste, and others infected only. Regardless of treatment, all periapical tissues

Inflammation and infection of pulp and periapical tissues

Oral Surgery, Oral Medicine, Oral Pathology, 1972
Abstract The state of our scientific knowledge concerning inflammation and infection of pulp and periapical tissues is reviewed with respect to the correlation and lack of correlation of this body of scientific fact with present-day clinical practice. Gaps in our knowledge are emphasized, and suggestions made as to possible paths of future research.

Influence of combinations of oral bacteria on periapical tissues of monkeys

European Journal of Oral Sciences, 1982
Abstract – 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, 1957
Summary 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.

Tissue Levels of Matrix Metalloproteinases in Pulps and Periapical Lesions

Journal of Endodontics, 2002
The 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.

MESENCHYMAL STEM CELL MARKERS IN PERIODONTAL TISSUES AND PERIAPICAL LESIONS

Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology, 2020
Mesenchymal stem cells (MSCs) are characterized by the potential to differentiate into multiple cell lineages, high proliferation rates, and self-renewal capacity, in addition to the ability to maintain their undifferentiated state. These cells have been identified in physiological oral tissues such as pulp tissue, dental follicle, apical papilla and ...

Influence on periapical tissues of indigenous oral bacteria and necrotic pulp tissue in monkeys

European Journal of Oral Sciences, 1981
Abstract – 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.
