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.

Genetic Polymorphism and Expression of Matrix Metalloproteinases and Tissue Inhibitors of Metalloproteinases in Periapical Lesions: Systematic Review.

INTRODUCTION: Recent studies involving genetic polymorphism and expression have provided information about their role in periapical lesions. This study aimed to evaluate if there is an association between the genetic polymorphism and gene and protein expressions of matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) in the periapical inflammatory response. METHODS: A systematic review was conducted through a rigorous search in electronic databases as well as a hand search. Two reviewers (κ = 0.90) evaluated the studies considering predetermined eligibility criteria, extracted data for interpretation, and finally used the Strengthening the Reporting of the Genetic Association statement to determine the quality of the scientific evidence. RESULTS: The initial search identified 251 studies. After excluding the duplicates and applying the eligibility criteria, 15 studies were eligible to be assessed in full. Two studies had grade A and 13 grade B quality according to the Strengthening the Reporting of the Genetic Association and were included. The selected studies showed that the periapical lesion tissue samples had a high concentration of MMPs; moreover, there was an expressive decrease in the concentration of MMPs and TIMPs in patients with periapical lesions after mechanical chemical preparation. In relation to genetic polymorphisms, MMP1, MMP2, MMP3, and MMP8 were associated with a higher risk of periapical lesions. Moreover, MMPs 1, 2, 3, 7, 8, 9, 13, 14, 16, and 25 and TIMP 1, 2, 3, and 4 can play an important role in the progression of periapical lesions. CONCLUSIONS: Based on articles with medium to high quality, MMPs and TIMPs are associated with the formation of periapical lesions (PROSPERO number: CDR42018100406).

Custom-made facemask as a coadjuvant in the postoperative treatment of sport-related facial trauma: Case report.

Maxillofacial injuries are a regular consequence of sport activities that can force athletes to take a long time off from training and competitions. One way to decrease the time that the athlete needs to get back to his or her training exercises after surgery is to use a custom facemask as a coadjuvant in the postoperative recovery phase. This case report describes the case of a 16-year-old male athlete who suffered facial trauma (orbitozygomatic fractures) during a soccer game. After surgery, a facemask was used during the postoperative phase. He returned to his regular physical activities only 3 weeks after surgery. This simple and very efficient procedure is a good option for athletes who suffer facial injuries.
