Improvement on OHRQoL after endodontic treatment associated with aPDT in traumatized primary teeth: a 12-month follow-up case report.

Dental trauma is often associated with a negative impact on the oral health-related quality of life (OHRQoL). The management of traumatized teeth is a challenge in the daily pediatric dentistry clinic, due to the sequels generated over time. Pulp necrosis is a frequent sequel that requires a pulpectomy. Antimicrobial photodynamic therapy (aPDT) is an adjuvant technique, effective in eradicating microorganisms from the root canals. This case report aimed to describe OHRQoL after endodontic treatment associated with aPDT in traumatized primary teeth of a 4-year-old female patient attended at a Dental Trauma Care Program considering a period of 12-month follow-up. The Brazilian version of the Oral Health Early Childhood Impact Scale (B-ECOHIS) was used to evaluate the OHRQoL. The dental trauma and its sequels had a negative impact on the child's OHRQoL. The proposed treatments (endodontic and restorative procedures) improved the patient's OHRQoL. The association of aPDT with conventional endodontic treatment was effective in this case. It allowed the sinus tract regression and new bone formation. Besides that, this case report emphasizes the need and importance to follow-up dental trauma cases in the pediatric dentistry clinic.
