The preparation of periapical lesions for flow cytometry

International Endodontic Journal, 2000
Aim  To devise an optimal protocol and to analyse the leucocyte composition of periapical (PA) lesions by flow cytometry.Methodology PA lesions were mechanically agitated, with and without proteolysis. This was with either 0.2% collagenase alone, or in combination with 0.02% DNA‐ase in serial incubations until all tissue was digested.

Periapical lesions and residual dental cysts

British Journal of Oral Surgery, 1970
DENTAL or radicular cysts commonly originate within periapical granulomas associated with non-vital teeth. The central cells of a proliferating clump of epithelium may undergo degeneration to form the nucleus of a cyst, or a cyst may arise from degeneration of a connective tissue core entrapped within a loop of proliferating epithelium (Fig. I, D).
