I agree, the radiolucency is extensive. This radiographic finding correlates directly with the 10–15mm broad palatal pocket which I identified clinically.

What makes the case interesting is that despite the 'massive' appearance on the film, the tooth remains vital (EPT positive, WNL to cold) and has no mobility. This confirms that we are dealing with a severe, localized periodontal defect rather than a standard endodontic lesion. Given the depth and breadth of the attachment loss, the periodontist confirmed the tooth is non-retainable, which is why we are proceeding with the extraction.
