Abstract

Background Some studies have been conducted to determine radiographic distortion on the various technique, including panoramic radiographic distortion on the vertical dimension and the horizontal dimension, Until now there is still no study on distortion of SLOB technique, therefore it was needed to eximine horizontal distortion by using inovative tool with modified film holder in SLOB technique particular', on permanent mandibular first molar. Purpose. To know the difference of distortion mesial and distal with 20 degrees angulation. Methods. Using analytical observation, the number of samples were 24 patients, lower permanent first molar teeth covered with wax and clasp, then the tooth photographed with the periapical projection using modified film holder in SLOB technique at the angle 20 degrees on mesial and distal, then clasp mesured using the term Boley Gauge to know its distortion. Result. There was significant difference between the use of the film holder modification techniques SLOB angulation 20 degrees to mesial and distal on permanent mandibular first molar. Conclusion. Angulation of 20 degrees to mesial and distal revealed a significant distorsion and suggested this technique merely use in qualitative study.
