Endodontic instruments becoming separated within the root canal is an undesirable occurrence. A different device prevents the root canal system from being completely debrided and sealed. As a result, every effort must be taken to recover the shattered instrument. When an instrument separates from the canal, the clinician is left in a state of despair, worry, and, finally, optimism that nonsurgical retreatment approaches will aid in the removal of the device.


The aim of the current study is to find the most common type of instrument separated during root canal treatment among 10 -70 years of age visiting private Dental College and Hospitals.



The current study is a descriptive study which is performed under university settings where the instrument retrieved data was collected from the Hospital Records management system at a Private Dental College. All the instruments fractured / separated during root canal treatment datas were collected.The sample size of the study was found to be n=40. The data was obtained and tabulated in excel, imported to SPSS software by IBM ,a statistical software with variables defined. The significance of this study was set at p<0.05,obtained using Chi square test and the results were interpreted.


From the statistical analysis, it is observed that the type of instrument separated has equal gender predilection and the most commonly involved age group  is  around 30 - 40 years. The most commonly involved tooth for instrument separation in both the arches was found to be canines and the most commonly involved type of instrument separation was found to be rotary files Chi square statistical test was done and the p value was found to be 0.492 (Chi square -p value >0.05,  not significant


 Within the limitations of the current study, it is found that instrument separation is more common among 30- 40 years of age with equal gender predilection, and higher incidence with canines.
