Guided Tissue Regeneration in Periapical Surgery

Journal of Endodontics, 2010
Tissue regeneration by using membrane barriers and bone grafting materials in periapical surgery is an example of tissue engineering technology. Membrane barriers and/or bone grafts are often used to enhance periapical new bone formation. However, the periapical tissues also consist of the periodontal ligament (PDL) and cementum.

Sodium hypochlorite injection into periapical tissues

Journal of Endodontics, 1989
Sodium hypochlorite is a useful adjunct to endodontic therapy but it must be confined to the root canal. A case of periapical injection of hypochlorite with untoward sequellae is presented.

Human periapical granulation tissue contains osteogenic cells

Cell and Tissue Research, 2004
Bone defects caused by periapical inflammation can be treated and improved by endodontic therapy. However, the mechanism for osseous healing of periapical lesions after root canal treatment is unclear. In this study we examined whether fibroblastic cells from human periapical granulation tissue could produce calcified matrix in vitro.

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

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

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 ...

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.

Periapical tissue reactions after pulp exposure in rat molars

Oral Surgery, Oral Medicine, Oral Pathology, 1975
Apical periodontal lesions were produced in the rat molar by exposing the pulp to the oral environment. The natural history of the undisturbed lesion was studied at time intervals ranging from 2 days to 1 year postoperatively. The earliest reactions were usually inflammatory infiltration at the apex.

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.

Cytokine expression in periapical granulation tissue as assessed by immunohistochemistry

European Journal of Oral Sciences, 2000
The aims of this study were to investigate the expression of pro‐inflammatory, anti‐inflammatory and immune‐related cytokines present in periapical lesions. We investigated the expression of cytokines: namely interleukins IL‐2, IL‐4, IL‐6, IL‐10 and interferon‐γ(IFN‐γ) in formalin‐fixed, paraffin‐embedded sections of periapical granulation tissue.
