Abstract
The purpose of this study was to compare differences in pocket reduction rate between different tooth types and sites after initial treatment. Forty-one adult periodontitis patients (mean age 40.8) whose O'Leary plaque records during inital treatment were maintained at a level of less than 10% (mean level 9.02± 4.93%) were selected for this study. A total of 5983 surfaces were monitored by recording probing pocket depths (P.P.D.).
The results obtained were as follows.
1. Significant probing pocket depth reduction was obtained following initial treatment (P<0.001).
2. Significantly improved teeth were 4 2 1 1 2 4 (p<0.001), 5 5 and 5 3 3 5 (p<0.05), and 3 2 2 3 (p<0.05). Deep residual P.P.D. were observed i n 1 1, 6 6, 7 7, 616 and 7 7 (p<0.001), and 2 2 and 3 3 (p<0.05).
3. Response to treatment by tooth type was favorable in 5 4 4 5 and 4 3 1 1 3 4 and was poor in 7 1 1 7, 7 7.
4. Mandibular residual pocket depths were much deeper on proximal surfaces than on the mid-facial and lingual surfaces. Maxillary pockets on palatal surfaces were significant deeper than on facial ones.
5. Poor response to treatment was treatment was observed on the mesiopalatal surfaces (p<0.001), mid-palatal surfaces (p<0.01) of 616 (p<0.001), the distolingual surfaces of 7 7, and 7 7 (p<0.001), and the mesio-palatal surfaces of 1 1 (p<0.05). Favorable responses were observed on the disto-buccal and the mid-palatal surface of 4 4 (p<0.05), mesiodistal buccal surfaces of 5 5 (p<0.05) and mesiolingual surfaces of 4 4 (p<0.05).
This results clearly indicate which tooth types and root surfaces must be paid careful attention to during treatment.
