The aim of the present review is to systematically evaluate the additive effect of autologous platelet concentrates (APCs) in treatment of intrabony defects when used along with other regenerative procedures and when used alone in terms of clinical and radiological outcomes. A search was performed in electronic databases (i.e., MEDLINE and the Cochrane Central Register of Controlled Trials) in order to identify randomized clinical trials (RCTs) assessing the additive efficacy of APCs for healing and regeneration of hard and soft tissues in patients undergoing regenerative surgical procedures for the treatment of intrabony defects, having a follow-up of at least 9 months. Included studies underwent risk of bias assessment and data extraction. The main variables evaluated for efficacy were: pocket depth (PD), clinical attachment level (CAL), radiographic bone filling, and postoperative pain. The effect of APCs adjunct was evaluated for the following procedures: open flap debridement (OFD) alone, OFD plus grafting of the defect with autogenous bone or bone substitutes, and grafting in combination with a covering membrane for guided tissue regeneration (GTR). Platelet-rich fibrin (PRF) has a significant additive effect when used along with OFD. Platelet-rich plasma (PRP) has a significant additive effect when used along with bone grafts. Conversely, PRP was found to be ineffective when used in combination with GTR procedures. No study evaluated the effect of APCs on postoperative pain. Platelet-rich plasma may be used advantageously as an adjunct to grafting materials, but not in combination with GTR, for treatment of intrabony defects. Moreover, PRF can be effective as a sole regenerative material, in combination with OFD. There is still a lack of evidence regarding the effect of PRF in combination with grafting materials and GTR, the effect of other types of APCs such as plasma rich in growth factors, and the effect of APCs on postoperative pain.
Herbal medicines have long been used as a traditional mode of therapy for various ailments in India. They are being used increasingly as dietary supplements to ward off common diseases. Periodontal diseases are highly prevalent and can affect up to 90% of the world population. Gingivitis is the mild form whereas periodontitis results in an irreversible loss of supporting structures of the teeth. Even though periodontal pathogens form a crucial component in the etiopathogenesis of periodontitis, there is a growing body of evidence suggesting oxidative stress playing a pivotal role in the disease initiation and progression. Studies have shown a direct correlation between increased levels of biomarkers for tissue damage induced by reactive oxygen species (ROS) to the severity of periodontal disease. Thus, the focus of attention has revolved back to herbal medicines due to their wide spectrum of biological and medicinal activities, lower costs, and higher safety margin. Internet databases Pubmed and Google Scholar were searched, and the most relevant articles were considered for review. This review briefly describes the various herbs with antioxidant capacity and their potency in the treating periodontal disease.
The adjunctive use of PRF in combination with barrier membrane is more effective in the treatment of intrabony defects in chronic periodontitis as compared with barrier membrane alone.
Sulfiredoxin is a recently discovered member of the oxidoreductases family which plays a crucial role in thiol homoeostasis when under oxidative stress. A myriad of systemic disorders have oxidative stress and reactive oxygen species as the key components in their etiopathogenesis. Recent studies have evaluated the role of this enzyme in oxidative stress mediated diseases such as atherosclerosis, chronic obstructive pulmonary disease and a wide array of carcinomas. Its action is responsible for the normal functioning of cells under oxidative stress and the promotion of cell survival in cancerous cells. This review will highlight the cumulative effects of sulfiredoxin in various systemic disorders with a strong emphasis on its target activity and the factors influencing its expression in such conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
