RESUMO
Context (Background): Periodontitis is an infectious inflammatory disease with increase in salivary Nitric oxide levels and Curcumin is known to inhibit inflammatory mediators and neutralize nitric oxide which is expressed in salivary glands. To evaluate and compare the possible improvement in parameters of periodontal disease and salivaryAim: nitric oxide levels in patients undergoing scaling and root planing (SRP) alone and scaling and root planing (SRP) with systemic curcumin administration. In one group, systemic curcumin will be administered along withSettings & Design: SRP & in another group only SRP will be performed. In Group A, SRP along with systemicMethods & Materials: curcumin was administered, and in Group B only SRP was performed. In both the groups, periodontal parameters such as the plaque Index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), presence or absence of bleeding on probing (BOP) and salivary nitric oxide (NO) levels by spectrophotometer were assessed at baseline and after three month. Chi-Square-test was used so as to evaluate and compare theStatistical Analysis used: possible improvement in parameters of periodontal disease and salivary nitric oxide levels in patients undergoing scaling and root planing (SRP) alone and scaling and root planing (SRP) with systemic curcumin administration. Results & Conclusions: Clinically significant results with improvement in clinical parameters and reduction in salivary NO levels were noticed in both the groups, although test group showed more reduction in the salivary NO levels when compared to the control group thus concluding that administration of systemic curcumin is effective against salivary NO levels and can be used as an adjunct to SRP.
RESUMO
Background: Soft tissue excision around natural teeth is carried out to increase the clinical crown lengths, expose the caries apical to the gingival margins and to correct irregular and un‑esthetic soft‑tissue contours. Aims: The study was carried out with an aim to evaluate the stability of the soft tissue margins after excision either with a laser or scalpel. Materials and Methods: A total of 20 patients indicated for soft tissue excision for correcting soft tissue discrepancies were selected. The patients with thick gingival biotype were included in the study. They were grouped randomly into excision by laser or scalpel methods. The change in the soft tissue positions from the time of excision to 1‑month follow‑up were evaluated immediate postoperatively, after 2 weeks and after 1‑month postrestoration. Results: The soft tissues remained stable in the laser group at 1‑month follow‑up, in contrast to the scalpel group and were found to be statistically significant, (Student’s t‑test) (P < 0.05). Conclusion: The soft tissue margins are more stable and stay at the point they were excised with lasers when compared with scalpel.
