Description
Wang and co-authors follow a ten-year-old girl whose injured front teeth faced a second accident, in this 2026 Case Reports in Dentistry article. After the first trauma, one incisor had its broken crown managed with a pulpotomy. The other developed external inflammatory root resorption, a process eating away at the root, plus infection around its tip. Regenerative endodontic therapy, which encourages the tooth's own tissues to heal, was used on the resorbing tooth.
Follow-up X-rays confirmed healing, with a clean border around the resorption site. Seven months after the first injury, a second blow concussed both teeth; no treatment was needed beyond monitoring. At twenty-six months both teeth stayed symptom-free and sound. The authors say the case shows regenerative therapy can stop root resorption durably, even through later mild trauma.
