MODIFIKASI SUDUT PENYINARAN VERTIKAL TERHADAP KEAKURATAN DIMENSI PANJANG GIGI KANINUS RAHANG ATAS PADA TIPE KEPALA MESOCEPHALIC DENGAN BISECTING TECHNIQUE RADIOGRAPHY

Abstract

Distortion is the alteration of radiograph images compares to the form of the actual object. Among other distortions caused by the placement of a film that is not correct, an error setting the angle of the head position settings, shines or the plains of occlusal, improvement of the object film distance (OFD), decreasing the distance with conus as well as due condition of the jaw, teeth and oral cavity of the patient. According to various references to the right of the vertical shines angle of the dimention accuracy of long of maxillary canine type mesocephalic head with bisecting technique radiography. Methods. This research is laboratory experimental research using a sample of maxillary canine elements planted on the model of the maxillary teeth by respondent type mesocephalic head previously done molding, casting, and drilling on the canine, then made the manufacture of radiograph with modification vertical angle +40o, +45o, +50o, and +55o using bisecting technique radiography. The observed variable is the difference in the long of the description of a radiograph of the canine at various angles and sought after corner with long teeth in a radiograph of the most close to the long of the actual teeth. The results of research conducted subsequent data analysis using a test one way anova test then proseceed with LSD. Results. The results showed there was a difference in the accuracy of dimentions long of maxillary canine using various vertical angles +45o angle is the most excellent shines vertically to obtain the accuracy of dimention long of maxillary canine.
