Comparison of the postoperative anti-inflammatory efficacy of chlorhexidine, saline rinses and herbal mouthwashes after mechanical debridement in patients with peri-implant mucositis: A randomized controlled trial.

AIM: The null hypothesis is that there is no difference in the post-operative anti-inflammatory efficacy of chlorhexidine (CHX), 2% saline rinses (SR) and a herbal mouthwash (MW) after non-surgical mechanical debridement (MD) for treatment of peri-implant mucositis (PiM). The aim was to compare the post-operative anti-inflammatory efficacy of CHX, 2% SR and a herbal oral rinse after non-surgical MD of PiM. MATERIALS AND METHODS: The present randomized controlled trial had a single-blinded parallel arm design. Patients diagnosed with PiM were enrolled. Demographic information was recorded. All patients underwent MD and were randomly divided into 4 groups: CHX-group: 0.12% non-alcoholic CHX; Sodium chloride (NaCl) group: 2% NaCl rinses; Herbal MW group: Herbal-based MW and H2 O group: distilled water with peppermint flavour. After MD, all the participants were advised to rinse twice daily (every 12 hrs) for 2 weeks with their respective MWs. In all groups, peri-implant modified plaque index (mPI), modified gingival index (mGI) and probing depth (PD) were measured at baseline and at 12 weeks of follow-up. Sample size was estimated using data from a pilot investigation; and group-comparisons were performed. Statistical significance was confirmed when P-values were below 0.01. RESULTS: Sixty individuals (15 patients/group) were included. At baseline, mPI, mGI and PD were comparable in all groups. At baseline, there was no significant difference in peri-implant mPI, mGI and PD in all groups. At 12-weeks' follow-up, there was a statistically significant reduction in peri-implant mPI (p < 0.01), mGI (p < 0.01) and PD (p < 0.01) in CHX, NaCl and herbal MW groups compared with H2 O group. There was no significant relation between implant location, duration for which, implants were functional, gender and peri-implant clinical parameters in all groups. CONCLUSION: After non-surgical MD, post-operative use of CHX and herbal and NaCl MWs is useful for the management of PiM in the short-term.

Postoperative Analgesic and Anti-inflammatory Effectiveness of Ginger (Zingiber officinale) and NSAIDs as Adjuncts to Nonsurgical Periodontal Therapy for the Management of Periodontitis.

PURPOSE: The authors hypothesize that ginger (Zingiber officinale) tablets and non-steroidal anti-inflammatory drugs (NSAIDs) are effective in reducing postoperative self-rated pain and periodontal parameters (plaque index [PI], gingival index [GI], and probing depth [PD], clinical attachment loss [AL] and marginal bone loss) following non-surgical periodontal therapy (NSPT) in patients with periodontitis. The aim was to compare the postoperative analgesic and anti-inflammatory effectiveness of ginger tablets and NSAIDs as adjuncts to nonsurgical periodontal therapy for the management of periodontitis. Materials and Methods: Patients with periodontitis were included. All patients underwent NSPT. In groups 1 and 2, patients received postoperative ginger (400 mg) and non-steroidal anti-inflammatory drugs (400 mg), respectively. Demographic data were collected, and full-mouth periodontal parameters (PI, GI, PD and CAL) were evaluated at baseline and at 7, 14 and 21 days. Self-rated pain scores were assessed at baseline, and at 24 h, 3 and 7 days of follow-up. In both groups, self-rated pain was assessed pre- and postoperatively using the numeric rating scale (NRS). Power analysis was performed on data from a pilot investigation and group comparisons were done. Statistical significance was set at p < 0.01. RESULTS: Baseline mean NRS scores in groups 1 and 2 were 4.19 ± 0.12 and 4.13 ± 0.08, respectively. All participants had stage II/grade B periodontitis. At baseline, self-rated pain scores were significantly higher among patients in groups 1 and 2 at 24 h (p < 0.01) and 3 days (p < 0.01) of follow-up. In groups 1 (p < 0.01) and 2 (p < 0.01), self-rated pain scores were significantly higher at 24 h compared with 3 days of follow-up. In both groups, there was a significant reduction in PI (p < 0.01), GI (p < 0.01) and PD (p < 0.01) at 7, 14 and 21 days of follow-up compared with baseline. CONCLUSION: Ginger and traditional NSAIDs are effective in reducing postoperative pain and inflammation following NSPT in patients with moderate periodontitis.

Analgesic Efficacy of Curcuma longa (Curcumin) after Surgical Periodontal Therapy.

PURPOSE: To compare the analgesic efficacy of orally administered Curcuma longa (curcumin) and mefenamic acid (MA) after surgical periodontal therapy (SPT). MATERIALS AND METHODS: Seventy-six periodontitis patients were randomly divided into two groups. In the test group, patients received curcumin capsules (200 mg), and in the control group, patients received MA (500 mg). All patients underwent post-operative antibiotic therapy using 500 mg amoxicillin and 400 mg metronidazole for 7 days. Post-operative pain and discomfort were evaluated using the numerical rating scale (NRS) and verbal rating scale (VRS), respectively. Evaluation were performed after 24 (T1), 48 (T2), and 72 h (T3). Group comparisons were done using Student's t-test and the Mann-Whitney U-test. The level of statistical significance was established at p < 0.05. RESULTS: All patients had stage 3/grade C periodontitis. The mean age of individuals in the test and control groups were 58.4 ± 7.3 and 57.2 ± 5.2 years, respectively. A family history of periodontal diseases was reported by 37.5% and 47.4% individuals in the test and control groups, respectively. In the test and control groups, the total mean duration of periodontal surgery was 168.2 ± 12.2 and 173.4 ± 10.7 min, respectively. There was no statistically significant difference in the mean NRS and VRS scores among patients in the test and control groups. In both groups, there was no statistically significant difference in the change in NRS scores at any time point. CONCLUSIONS: Compared with MA, curcumin is ineffective for pain and discomfort management after SPT. The possibility of the results being biased due to lack of operator blinding cannot be overlooked.
