A case report of triple dental injury: from the replantation to extraction in 27 years

Preventive dentistry has undergone significant advancements in recent years, leading to a shift in the causes of tooth loss. In contrast, dental injury has emerged as the leading cause. Objective: This study presents a case involving multiple dental injuries at the permanent maxillary left central incisor (21) during a 27-year follow-up. Case report: An 18-year-old male patient suffered a dental injury that resulted in a root fracture and avulsion of 21. Tooth replantation was performed 90 minutes after the accident. After 30 days, the endodontic treatment was performed. Thirteen years later, the patient presented to the dental office with a complaint of pain after internal and external dental bleaching. Radiographic signs of root resorption were observed. Endodontic retreatment was then carried out. Twenty-three years from the first trauma, the same tooth suffered a lateral luxation. Twenty-seven years after tooth replantation and four years after stabilization due to lateral luxation, 21 suffered a cervical horizontal root fracture. Thus, extraction was performed. Conclusion: This case report’s singularity is the long follow-up time associated with the sequence of events, including different types of dental injuries and bleaching. In addition, sharing treatment strategies can suggest insights for future studies and help other professionals with similar situations.
