    Undergraduate students encounter challenges with the bisecting angle technique in endodontic radiography, particularly with maxillary teeth and rubber dam use. Distortion, superimposition, and missed root apices are common issues needing solutions.

    Area of Science:

    • Dentistry
    • Radiology
    • Endodontics

    Background:

    • The bisecting angle technique is a fundamental method for endodontic radiography.
    • Accurate radiographic interpretation is crucial for successful endodontic treatment.
    • Undergraduate dental students may face specific challenges in mastering radiographic techniques.

    Purpose of the Study:

    • To identify and highlight common problems encountered by undergraduate students using the bisecting angle technique in endodontic radiography.
    • To assess the impact of specific factors, such as tooth type and the presence of rubber dam equipment, on radiographic accuracy.

    Main Methods:

    • A retrospective survey design was employed.
    • Radiographs of maxillary and mandibular incisors and premolars taken by undergraduate students were analyzed.

  • Specific radiographic errors, including distortion, superimposition, and apex visualization, were evaluated.

    • Main Results:

    • Maxillary incisors and premolars exhibited greater distortion compared to mandibular teeth.
    • The presence of rubber dam equipment significantly affected radiographic accuracy, especially for maxillary anterior teeth.
    • Other identified issues included superimposition and indistinct or missed root apices.

    Conclusions:

    • The bisecting angle technique presents specific challenges for undergraduate students in endodontic radiography.
    • Maxillary teeth and the use of rubber dam equipment require particular attention to improve radiographic quality.
    • Implementing targeted educational strategies can help overcome these identified problems and enhance diagnostic accuracy.
