Popis:	Experimental periodontitis was induced in the premolars of two adult beagle dogs by cotton ligature placement and administration of a soft diet that facilitated plaque accumulation over 24 weeks. Periodontal flap surgery, including root planing was carried out by using curettes and root demineralization with 0.3 N hydrochloric acid (HA) for 5 min. In the HA-demineralized group, new cementum formation was seen on the non-resorbed dentin surfaces, and the newly formed cementum matrix fibers became interlaced and/or attached to the exposed dentin matrix fibers through an amorphous granular substance. In the non-HA-demineralized control group, the regenerated junctional epithelium covered the planed dentin surface, and no new cementum formation was observed. The present study suggests that 0.3N HA treatment can induce the formation of new connective tissue attachment to a previously diseased root surface.
