Periodontal inflammation are inflammation of supporting tissues of periodontium. The microbial factor can cause infection which is polymicrobial in origin and causes dysbiosis and shift in oxidative stress with compromised antioxidant capacity. This study focused at determination of the effect of nonsurgical periodontal therapy (NSPT) and vitamin C supplementation on total antioxidant capacity (TAOC) in chronic periodontitis patients (ChP). A total of 70 ChPand 35 periodontally healthy subjects (control) were recruited in this study. Further, ChP group was subdivided into ChP1 group (n = 35) which received NSPT only and ChP 2 group (n = 35) which received NSPT with vitamin C 500 mg once daily for 3 months. Serum and saliva samples were taken at baseline and at 3 months postNSPT for measurement of TAOC. Clinical parameters measured were measured at 1-, 3-, 6- and 12-month interval. Lower levels of serum and salivary TAOC levels were observed in ChP patients than healthy subjects (p < 0.05). Improvement in Clinical parameters was observed in both the groups ChP1 and ChP 2 group post therapy (p < 0.05). The periodontal treatment showed insignificant changes in serum and salivary TAOC levels (p > 0.05). The supplemental dose of vitamin C didn't have any additional benefits (p > 0.05). There lies an association of oxidative stress with periodontitis, low serum and salivary TAOC levels were seen in chronic periodontitis patients. NSPT improved the periodontal inflammatory status. However, benefits of vitamin C as an adjunct to NSPT remains inconclusive and needs to be further explored by multicentre longitudinal studies.

Objective: This clinical investigation evaluated oral health improvements after the use of a novel zinc toothpaste in comparison to a control after 3 weeks and 6 weeks of use. Clinical assessments of gingivitis, bleeding and dental plaque evaluated oral health. Methods: Healthy adults meeting the study criteria (plaque index scores ≥ 1.5 and gingival index scores ≥ 1.0) were randomized into a treatment group with 74 participants assigned to the test and 73 participants assigned to the control groups. With the assigned toothpaste, subjects were instructed to brush at home twice a day for one minute. Subjects were evaluated clinically for gingivitis, plaque and bleeding at the baseline, employing 3-week and 6-week examinations. Results: All one hundred and forty-seven (147) subjects completed the 6-week study with no significant differences between groups at baseline (p > 0.05). The test demonstrated progressive improvements at the 3-week and 6-week evaluations as compared to the control (p < 0.001). In comparison to the control, the test demonstrated reductions of 13.4%, 17.0% and 55.3% for gingivitis, dental plaque and gingival bleeding, respectively, at the final visit (p < 0.001). Conclusions: Clinical improvements in gingivitis, dental plaque and gingival bleeding were registered in the group assigned the test toothpaste as compared to the control. The test toothpaste demonstrated statistically significant and progressively improving gingivitis, dental plaque and gingival bleeding scores that were all statistically significant versus the control at each post-treatment assessment.
