An associations between bony changes in the marginal interproximal areas on bisect. ing-angle technique radiograms and clinical findings (Plaque Index: PI, Probing Depth: PD, Calculus Index: CI, Bleeding Index: BI, Gingival Index: GI, Teeth Mobility: TM) related toperiodontal disease were examined. Subjects were 31 prosthodontic patients with the early stageof periodontal lesion (Table 3).
1. Regarding the bone height, significant association was found between the bone scoreand PD (P<0.005), CI (P<0.005) and TM (P<0.0005).
2. Regarding the type of bone defect, frequency of H-type of bone loss was higher in thesamples with dental calculus than in ones without dental calculus (P<0.05).
3. Significant relations were also detected between continuity of the lamina dura and CI (P<0.05).
4. As to periodontal space, no significant clinical finding existed so far as we examined.
