Purpose: To evaluate changes in the periodontium of teeth restored with ultrathin (0.2 to 0.39 mm) ceramic laminate veneers (CLVs) placed subgingivally without a finish line compared to the same teeth before restorative treatment and to nonrestored antagonist teeth in healthy periodontium patients. Materials and Methods: A total of 73 CLVs were bonded onto the enamel surface of teeth without a finish line and with the cervical margin placed about 0.5 mm subgingivally. The gingival crevicular fluid was collected before bonding (baseline) and at 7, 180, and 365 days after bonding to quantify S mitis, P intermedia, and P gingivalis by quantitative polymerase chain reaction analysis. Visible plaque index (VPI), bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL), gingival recession (GR), and marginal adaptation were evaluated from baseline to 365 days in both groups. Results: No statistically significant differences were observed in VPI, PD, or BOP at any time point in the intragroup or intergroup comparisons (P > .05). All restorations obtained the alpha concept for marginal adaptation (ie, the restoration margin remained ideal at all time points). There was a statistically significant difference for S mitis between 180 and 365 days (P = .03). No statistically significant difference was observed for P gingivalis at any time point (P > .05). Conclusion: The periodontium in the restored group showed a clinical behavior similar to baseline. Overcontouring of the ultrathin (up to 0.39 mm) CLV, similar to the cementoenamel junction convexity, did not contribute to plaque accumulation or changes in the oral microbiota of patients with a healthy periodontium and proper oral hygiene instruction.

O presente trabalho tem como objetivo relatar o caso de uma criança com 1 ano e 8 meses, em mau estado geral e choque hipovolêmico, atendida na urgência com edema agudo hemorrágico da infância (EAHI), ou a sua variante: Púrpura de Schoenlein-Henoch (PHS). As informações foram obtidas por meio de revisão de prontuário, entrevista com mãe do paciente, registro fotográfico dos métodos diagnósticos ao quais o paciente foi submetido e revisão da literatura. O caso relatado e as publicações pesquisadas trazem à luz a discussão do diagnóstico de uma situação complexa que é a doença meningocócica e o EAHI em suas várias formas, bem como na terapêutica mais adequada em momento de urgência. Descritores: Púrpura de Schoenlein-Henoch; Vasculite; Meningite.This paper aims at reporting the case of a 1 year and 8 months old child who was in a bad general state, and was admitted at the emergency room while going through hypovolemic shock, with acute hemorrhagic edema of infancy (AHEI) or its variant: Henoch -Schoenlein purpura (HSP). Information was obtained through a review of medical records, an interview with the patient, a photographic register of the diagnostic methods to which the patient was submitted. A literature review was also conducted. The reported case and the publications researched bring to light and discuss the diagnosis of a complex situation, which involves the menigococcal disease and the AHEI in its various forms, also discussing the proper therapy in urgent cases.
