Abstract
Our study was undertaken to establish a rational system for the dental care management and treatment of periodontal disease in mental deficient adults.
42 mental deficient adults were selected for this study. Following an initial examination comprising assessments of plaque accumulation rate (Pl. R), gingival index (G. I) and pathological pocket rate (Po. R), all participants were subjected to oral hygiene instruction only during 6 months.
At the 6 months reexamination, all participants were divided into two groups (A and B). Namely, the A-group consisted of 17 subjects who had Pl. R of≥26%, while the B-group consisted of 28 individuals who had Pl. R of≤25%.
For the subsequent 6 months, the A-group subjects were given oral hygiene instruction only as well as the first 6 months, while the B-group subjects were treated by scaling in conjunction with oral hygiene instruction.
The results were as follows:
1. In the A-group during the first 6 months (0-6M) there was significant decrease of Pl. R and G. I, but at subsequent 6 months (7-12M) Pl. R only had significantly improved.
2. In the B-group, during the first 6 months there was significant decrease of Pl. R, G. I and Po. R, but at subsequent 6 months G. I only had significantly improved.
3. In the B-group subjects who had Pl. R of≤25% at the 6-months reexamination, a great number of teeth with initial probing depth≥4mm were improved in probing depth≤3mm by oral hygiene instruction only.
The rates of the improvement were 91.2% for the teeth with initial probing depth 4mm, 51.9% for 5mm, 42.3% for 6mm, respectively.
4. In the B-group subjects, who were given scaling in conjunction with oral hygiene instruction between 7-12 months, the rates of the improvement at the 12 months reexamination were more increased than the 6 months reexamination.
The rates of the improvement were 94.7% for initial probing depth 4mm, 63% for 5mm, and 61.5% for 6mm, respectively.
But the rates of the improvement for the teeth with initial probing depth≥7mm were extremely low.
