Ensuring clinical success begins with a careful discussion of treatment planning, comprehensively covering all variables in simple to complex cases. Procedures including the crown lengthening surgery, furcation treatment and mucogingival therapy and tooth restoration are essential treatment regimens requiring multifaceted expertise. The interplay of periodontics and restorative dentistry is present at many fronts including the response of the gingival tissue to the restorative preparations. Dental restorations and periodontal health are inseparably interrelated. The adaptation of the margins, the contours of the restoration, the proximal relationships and the surface smoothness have a critical biological impact on the gingiva and the supporting periodontal tissues. The different surgical procedures used for crown lengthening are gingivectomy/gingivoplasty, apically positioned flap with or without osseous resection and orthodontic extrusion. The paper presents crown lengthening of severely mutilated teeth to increase the clinical crown height for adequate restoration.

Background:C-reactive protein (CRP), an acute-phase protein monitored as a marker of inflammatory status, has been identified as a major risk factor for various systemic diseases. It is a reliable marker to infectious burdens and/or inflammation. The aim of this study was to compare and evaluate the systemic levels of CRP in the serum sample of the patients with healthy gingiva, gingivitis, and chronic periodontitis.Materials and Methods:A total of 60 systemically healthy patients were selected and divided into three groups: Patients with healthy gingiva (Group A), patients with generalized gingivitis (Group B) and patients with chronic periodontitis (Group C). Peripheral blood was collected and high-sensitive (hs)-CRP levels were estimated in the serum samples by using the particle-enhanced turbidimetric immuno-assay technique using a commercially available kit.Results:The mean hs-CRP level in Group A recorded was 0.437 ± 0.216, Group B was 0.771 ± 0.384 and Group C was 2.285 ± 0.381. A significantly elevated hs-CRP level was found in Group C as compared with Group B and A (P < 0.05). However, a moderate, but statistically significant increase in the hs-CRP levels was observed in Group B as compared with Group A (P < 0.05). The percentage of patients with elevated levels of hs-CRP >2 mg/l was significantly higher in Group C.Conclusion:The patients with chronic periodontitis demonstrated a mean hs-CRP levels higher than the patients with gingivitis and with healthy gingiva. Furthermore, with the increasing inflammation, the hs-CRP levels increased proportionately.
