치은 염증 상태에 따른 치주낭 측정 깊이와 방사선학적 측정 깊이, 외과적 측정 깊이의 비교 연구

Abstract

The purpose of this study was to evaluate relationship of probing attachment levels, radiographic measurements and surgical measurements according to gingival inflammatory condition. Patients with incipient to moderate periodontitis were selected. Upper and lower premolar and molar teeth excluding third molars were measured. At first visit, gingival index and bleeding on probing were taken, and subjects were grouped into 4 categories as follows ' Experimental group I: gingival index 1 and no bleeding on probing. Experimental group II: gingival index 2 and no bleeding on probing absent. Experimental group III: gingival index 1 and bleeding on probing present. Experimental group IV: gingival index 2 and bleeding on probing present. Probing attachment levels were measured with manual probe on mesial and distal surfaces from cementoenamel junctions to terminal ends of probe. Radiographic measurements were made to assess bone loss by measuring the distance from cementoenamel junction to the alveolar crest. After thorough scating, a flap was raised exposing the alveolar bone and surgical measure- ments were made from cementoenamel junction to alveolar bone. The results were as follows: 1. Differences between probing attachment level and radiographic measurements showed 1.01+-0.73mm for experimental group l, 0.98+-0.48mm for experimental group II, 0.59+-0. 66mm for experimental group III, 0.98+- 0.38mm for experimental group IV and with no significant difference between groups. 2. Differences between probing attachment level and surgical measurements showed 1.36+- 0.80mm for experimental group I, 1.47+- 0.54mm for experimental group II, 1.06+- 0.1가39 mm for experimental group III, 1.41+- 0.40mm for experimental group IV and with no significant difference between groups. 3. Differences between surgical and radiographic measurements showed 0.36+- 0.48mm for experimental group I, 0.51+-0.54mm for experimental group II, 0.57+-0.72mm for experimental group III, 0.41+-0.49mm for experimental group IV and with significant difference between experimental group I and experimental group II, III, IV(P<0.05).
