This study is a parallel group randomized, Double-blinded, Placebo-controlled clinical trial The follow up of this study is set to be in a three months interval in order to monitor the effect of the periodontal treatment with/without vitamin B-3 and B-9 supplement on the periodontal repair and regeneration~The eligible patients will be randomized into three groups with four interventions:~Non-surgical scaling and debridement with placebo~Non-surgical scaling and debridement with vitamin B-3~Non-surgical scaling and debridement with vitamin B-9 Before intervention, a gingival cervicular fluid sample will be collected for all groups to measure the myeloperoxidase level at baseline before treatment then a full mouth scaling and debridement will be done by the primary investigator using ultrasonic scaler and periodontal curettes. After the non surgical treatment patients will be given oral hygiene instructions where they will be instructed to brush twice daily and shown how to brush using the horizontal scraping technique they will also be instructed to use the dental floss and shown how to use it. The systemically administered vitamin B or placebo capsules will then given to the patients and instructed to be taken once daily for 30 days. Patients are instructed not to take any vitamin B supplementations during the period of treatment, patients are also instructed to discontinue using the drug if any allergic reaction appeared and directly report it to the investigator.~Periodontal maintenance appointments which will include a review of medical and dental histories, supra- and subgingival instrumentation if needed, and oral hygiene instructions and motivation will be performed at 14, 30, 60 and 90 days.
this study addresses the effect of the vitamin B3 and vitamin B9 on the periodontal healing at the sites of periodontal destruction due to periodontitis and evaluate its added effect to the conventional non-surgical periodontal treatment on its pivotal role in the biological activities and repair in the body in general and the periodontium in specific. The research will be conducted on patients suffering from stage I and II periodontitis that typically are to be treated with non surgical periodontal therapy, the rationale of the non surgical periodontal treatment is eliminating the plaque biofilm responsible for stimulation of host immune defense causing the inflammation and hence suppressing the periodontal destruction.~the trial is targeting enhancing the treatment effect by the administration of vitamin B3 and B9 supplements which will target the host inflammatory reaction itself and directly suppressing it as well as enhancing the periodontal regeneration and the gain of the lost attachment.
