Effectiveness of custom-designed pointed laser light for teaching intraoral radiographic technique to undergraduate students: A comparative study.

Objectives: Intraoral periapical radiographic techniques are mandatory exercises taught to undergraduate students during their training. The key challenges encountered while teaching the bisecting angle technique (BAT) include correctly positioning the X-ray cone and adjusting the central X-ray beam to the tooth of interest. To address this, a custom-designed pointed laser light (CDPLL) was fabricated and attached to the X-ray cone.
