Should the third molar be extracted (Fig.1 (trimmed panoramic X-ray taken prior to #2 fracture): #1). In this case, no, because there is an opposing tooth (#32). More important with the 3rd molar present, the immediate provisional at the site of #2 is more stable. The prominent pathology associated with the tooth #1 is the enamel pearl in the mesial root surface (*), which is removed after #2 extraction (Fig.2: #1).
