RETROSPECTIVE EVALUATION OF SEPARATED INSTRUMENTS TO THE TYPE OF USED FILE , TOOTH TYPE, CANAL TYPE AND PORTION OF CANAL- DATA ANALYSIS IN UNIVERSITY SETTING

Instrument separation is a common occurrence during the endodontic treatment due to the use of hand or rotary files, Gates Glidden burs, lentulo, pluggers, spreaders made of different materials like NiTi, stainless steel. The mishap of instrument separation is a frustrating situation for the endodontist as it prevents access to the apex and impedes full length instrumentation and obturation of the root canal. Aim: This study evaluated the separated instruments to the type of used file, tooth type, canal type. Materials and method: There were a total of 78 instrument separation cases from June 2020- March 2021 that were evaluated. Patient details like age, gender, tooth type, canal type, portion of canal, type of instrument and method of retrieval were included in the study. The collected Data was analysed using SPSS. Results: The odds for rotary instrument separation were higher than the hand instruments with 57%. The probability of separating a file in the coronal third was more compared to the apical and middle third. The highest percentage of instrument separation in the mandibular posteriors with 36%. Furthermore, the odds of file separating in a single canal (38%) and mesiobuccal canal (19%) were higher. There was no significant difference (p>0.05) in instrument separation between type of instrument and portion of canal involved.
