Association among COVID-19, multisystem inflammatory syndrome in children, and oral health status.

The pathophysiology of multisystem inflammatory syndrome in children (MIS-C) and associated oral symptoms have not been clarified yet. The aim of the present study was to compare the oral health status of children with MIS-C-associated Coronavirus disease 2019 (COVID-19) and COVID-19. A total of 54 children with SARS-CoV-2 infection, 23 with MIS-C-associated COVID-19 and 31 with asymptomatic, mild, and moderate COVID-19 were recruited for the present cross-sectional study. Sociodemographic variables, medical examinations, oral hygiene habits, and extraoral and intraoral findings (DMFT/dmft index, OHI scores, and oral mucosal changes) were recorded. The t-test for independent samples and the Mann-Whitney U test were used (p < 0.05). MIS-C was found to be associated with chapped lips (all patients) and oral mucosal changes, including erythema, white lesion, strawberry tongue, and swelling of the gingiva as compared to the COVID-19 group (frequency of more than one mucosal change: 100% vs. 35%) (p < 0.001). Children with MIS-C presented higher DMFT/dmft scores (DMFT/dmft 5.52 ± 3.16 for the MIS-C group vs. 2.26 ± 1.80 for the COVID-19 group) (p < 0.01). Elevated OHI scores were also associated with MIS-C (mean ± SD: 3.06 ± 1.02 (MIS-C) vs. 2.41 ± 0.97 (COVID-19) (p < 0.05). Oral manifestations, mainly strawberry and erythematous tongue, were characteristic features of MIS-C. Prevalence of oral/dental symptoms was elevated in children with MIS-C when compared to COVID-19. Therefore, dental professionals should be aware of the oral manifestations associated with MIS-C, which may have high mortality and morbidity rates.

Therefore, dental professionals should be aware of the oral manifestations associated with MIS-C, which may have high mortality and morbidity rates.

Effectiveness and predictability of titanium-prepared platelet-rich fibrin for the management of multiple gingival recessions.

OBJECTIVE: Titanium-prepared platelet-rich fibrin (T-PRF) is activated with titanium, which results in a more mature and aggregated form than PRF. In our previous studies, we established that the fibrin carpet formed with titanium had a firmer network structure, and longer resorption time in the tissue than the fibrin carpet formed with glass. The purpose of this randomized controlled clinical trial is to compare the effects of autogenous T-PRF and connective tissue graft (CTG). MATERIALS AND METHODS: A total of 114 Miller Class I/II gingival recessions with abrasion defects were treated either T-PRF (63 teeth) or CTG (51 teeth) using a modified tunnel technique. Clinical periodontal indexes, keratinized tissue (KTW), gingival thickness, and recession depth were recorded before surgery and at 6- and 12-month follow-up examinations. The visual analog scale and healing index scores were assessed. RESULTS: The mean root coverages were 93.29 and 93.22% in the T-PRF and CTG groups, respectively, at 12 months post-operatively. CTG resulted in greater gingival thickness than T-PRF at 6 and 12 months post-surgery compared to baseline. Furthermore, the mean amounts of KTW increased by 1.97 and 0.75 mm in the T-PRF and CTG groups, respectively. CONCLUSION: Within the limits of this study, the results demonstrated that T-PRF is safe and effective for treatment of multiple Miller Class I/II gingival recession defects. CLINICAL RELEVANCE: T-PRF can serve as a good autogenous alternative to CTG, which is the gold standard for root coverage.
