Background . Immediate single implant placement and restoration (IIR) is recognized as a novel method and is the main request of many patients. This study was designed to evaluate the aesthetic outcomes of immediately restored single implants placed in extraction sockets in theanterior maxilla. Methods. In this case series study, 18 patients were selected from two private clinics after placing a single-tooth implant in the anterior maxilla. Immediate provisional crowns were delivered on the following day or at most 48 hours later, and guidelines were provided. The Pink Esthetic Score (PES) questionnaire was used at 6- and 12-month follow-ups to assess aesthetic outcomes. Data were analyzed with single t-test and dependent t-test. Results. In general, the results showed that the status of the mesial papilla, distal papilla, curve of the facial soft tissue line, level of the facial peri-implant mucosa and root convexity soft tissue in IIR method were optimal (P<0.05), with total PES means of 9.44±0.783 and 8.58±1.003 after 6 and 12 months, respectively. Also, the results showed a significant difference in PES between the 6-month and 12-month intervals (P<0.05). Conclusion. IIR is a viable method that resulted in optimal aesthetic outcomes based on PES in the short term. Considering its confirmation in this study and previous studies, it is recommended that dentists apply this method.

Background: Metabolic Syndrome (MetS) is a collection of conditions that puts people at an increased risk of cardiovascular disease. Objectives: The present study aimed to evaluate the association of periodontal disease severity and its parameters with MetS in a group of northwestern Iranian patients. Methods: The current study was conducted on 100 participants aged 25 - 78 (50 patients with MetS and 50 without MetS). Clinical and laboratory characteristics, periodontal components, including clinical attachment level (CAL), pocket depth (PD), and bleeding on probing (BOP), and the number of missing teeth were recorded. The differences between the two groups were evaluated by an independent sample t test. Results: The MetS group demonstrated significantly higher CAL, BOP, and missing teeth, which markedly increased by the number of MetS components. Nonetheless, the two groups did not reflect any difference in PD. Moreover, compared to participants without MetS, patients afflicted with MetS presented with more severe periodontal disease. Furthermore, CAL, BOP, and missing teeth were higher in patients with dyslipidemia, hypertension, and central obesity without dysglycemia than in the control group (P < 0.05). Conclusions: MetS patients demonstrated more severe periodontal disease, and the number of MetS components increased the odds of the disease. In addition, higher periodontal parameters (except for PD) were detected in participants with MetS. Moreover, no considerable change was observed in the obtained results upon the elimination of diabetic patients.
