Artificial periodontal defects and frequency of tooth brushing in beagle dogs (II). Clinical findings after a period of healing.
This investigation was designed to determine the influence of different frequencies of tooth brushing on artificial periodontal defects in the beagle dog after a period of healing. In 12 beagle dogs, periodontal defects were created using elastic bands placed in the sulci below the gingival margin after having cut the dento-gingival fibres to the level of the alveolar bone crest. This active phase of creating defects lasted for 6 weeks. After removal of the elastic bands, the created defects were left undisturbed during the remainder of the pre-experimental period (12 weeks). 6 premolars in the lower jaw were used (2P2, 3P3, 4P4). After the pre-experimental period, the 12 dogs were distributed into 3 groups of 4 dogs each. Each group was brushed with a certain frequency, i.e., 7 times, 3 times or once a week. Registrations of plaque index, gingival index and probing depth using a constant force probe were carried out on approximal surfaces. The experiment lasted for 24 weeks. A brushing effect was calculated for each dog to include information on all within-dog and between-dog variations. It was shown in relation to artificially-induced periodontal defects in beagle dogs that after a period of healing, brushing 7 times a week is superior to brushing 3 times a week in establishing and maintaining gingival health.
