COMPARSION BETWEEN PANORAMIC PERIAPICAL AND VERTICAL BITEWING RADIOGRAPHY IN DIAGNOSIS OF PERIODONTAL BONE LOSS

Abstract

Introduction. For diagnosis and treatment planing and detection the quality of remaining Alveolar bone the radiography is very useful so the type of radiography is very important. The purpose of this study is the comparison between panoramic, periapical (bisecting technique) and vertical bitewing radiographs in diagnosis of periodontitis.
Methods. Twelve patients (3 male and 9 female) with a mean age of 35, with a moderate to advanced periodontitis were evaluated. At the time of periodontal surgery, in the posterior site of two jaws (in 6 and 7 teeth), the bone loss was measured from CEJ to the base of alveolar bone, and compared with the radiographic findings of proximal bone loss.
Results. The average of distance between CEJ and alveolar bone in 48 surfaces were 4.27 in clinic, 4.80 in panoramic, 2.62 in periapical (bisecting technique), 2.98 in vertical bitewing and 4.05 in panoramic without magnification.
Discussion. In this research we cancluded that both techniques (periapical and vertical bitewing) are not accurate in detection of proximal bone loss and there was significant difference between quantity of proximal bone in clinical measurment than radiographic measurment and this study showed that the panoramic (specially panoramic without magnification) is more careful than other radiographic techniques in detection of proximal bone loss.
