Dental plaque is one of the major causes of periodontal diseases, and the management of dental plaque is the best way to prevent periodontal diseases. There are two ways to take care of dental plaque. One is self-care, and the other is professional care. Self-care isn’t efficient enough to ensure the perfect control of dental plaque, and assistance from dentists or dental hygienists is required. The purpose of this study was to make a case analysis of the application of a professional dental plaque management program by a dental clinic in an attempt to lay the solid foundation for the
settlement of systematic dental plaque control programs. A case study was implemented from May 8, 2006 to August 29, 2008. The subject was a male patient who was at the age of 43. 1. In the first dental examination, his plaque index(O’Leary index), BOP(bleeding upon probing) and supra & subgingiva calculus rate were all 100 percent. His pocket depth was 2 to 7mm, and there was a deeper pocket in part, which was 5 to 7mm in depth. 2. After the program was applied, he showed an improvement in the plaque index(O’Leary index), BOP, supra & subgingiva calculus rate and pocket depth, which respectively dropped to 25 percent, 31.3 percent, 8.9 percent and from 3mm. 3. When he paid a revisit a year and five months later, however, his plaque index (O’Leary index) was 28.2 percent, which showed that he didn’t pay careful attention to dental plaque self-care. He bled less in the revisit than in the second examination immediately after the application of the program, as his BOP was 16 percent. But the pocket depth was of 4 to 6mm, which was deeper than it was in the first examination. It meant that he had a return of the periodontal disease.
