- Abstract
The present pilot study was designed to examine the healing sequence when cells from the PDL are allowed to migrate coronally and populate the curetted root surface. Mucoperiosteal flaps were reflected around the premolars and mandibular incisors of two beagle dogs with naturally-occurring periodontal disease. The roots were thoroughly planed, and grooves were marked at the level of the crest of remaining alveolar bone. Millipore filters (pore size 3 microns) were adapted circumferentially to the roots and sealed to the teeth above the CEJ with cyanoacrylate before suturing the flaps. Histologic analysis of the experimental and sham-operated control teeth was done at 5, 7, 8, 10, and 12 weeks after the surgery. An initial phase of root resorption was followed by new connective tissue attachment coronal to the groove in successful experimental teeth. No new connective tissue attachment could be seen in the controls although the JE appeared to be located slightly coronal to the groove with time. The findings of the present study suggest that the chances of obtaining a new connective tissue attachment may be enhanced if surgical procedures are designed to allow selective population of curetted root surfaces by cells arising from the PDL.
