The X-ray picture is not complete because the end of the root which is the most important area to assess the completeness of root canal treatment, is missing. Nonetheless, there seems to be a broken portion of instrument in the canal and tooth definitely requires repetition of root canal treatment if extraction is to be avoided. Although I have to point out that it might not be definitely possible to retrieve that broken instrument but nonetheless an effort should definitely be made because extraction is always kept as the last option.
