It causes localized inflammation, due to various inflammatory mediators such as cytokines and chemokines. These inflammatory mediators are responsible for various reparative and resorptive processes in the dental pulp. The balance between these processes ultimately determines the viability of the tooth. Due to the important properties of various inflammatory markers, the correlation of cytokinin gene expression in various stages of inflammation becomes necessary to focus on. Several studies in the past have focused on the importance of such correlation to help in diagnostic applications. The nature of these inflammatory mediators can help us in diagnostic evaluation. Several attempts have been made to focus on these associations so that it can assist in making clinical decisions effectively. The data available are vast but are the most neglected topic. This review article briefly outlines and summarizes the importance of various inflammatory mediators such as cytokinin and chemokines in various pathways of pulpal and periapical inflammation in explanatory and diagrammatic forms. Knowledge gained about pulpal inflammatory response may aid in understanding the molecular level of inflammatory pulpal and periapical diseases, which shall modify our future diagnostic modalities. Several medicaments are used in the treatment of minimal to advanced dental caries which leads to periapical infections. Thorough understanding of these medicaments can resolve secondary infection and can improve the prognosis of the treated tooth.","PeriodicalId":516572,"journal":{"name":"Journal of Conservative Dentistry and Endodontics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140274940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aims to evaluate and compare the effect of herbal antioxidants on SBS of composite resin to bleached enamel at different time intervals.\u0000 \u0000 \u0000 \u0000 Sixty extracted single-rooted maxillary incisors postdecoronation, keeping their labial surfaces up were mounted in cold-cure acrylic resin. The samples were randomly divided into: Group I – unbleached; Group II – 10% pine bark extract for 10 min postbleaching; Group III – 10% pine bark extract for 20 min postbleaching; Group IV – application of 10% rosemary extract for 10 min postbleaching, Group V – application of 10% rosemary extract for 20 min postbleaching; Group VI – no application of antioxidant. 35% hydrogen peroxide was used for bleaching all the samples except those which served as negative control. Later composite cylinder 4 mm in diameter and length were built on prepared enamel. The maximum load at failure was recorded using the universal testing machine.\u0000 \u0000 \u0000 \u0000 Data were analyzed using the analysis of variance and Tukey’s t-test with significance level of P < 0.05.\u0000 \u0000 \u0000 \u0000 Highest load was exhibited by Group I. Group V showed satisfactory shear strength followed by Groups IV, III, II, and VI.\u0000 \u0000 \u0000 \u0000 Both 10% rosemary and 10% pine bark extracts showed better results when applied for 20 min as compared to 10 min application. Increased duration of antioxidant application increases the SBS.\u0000","PeriodicalId":516572,"journal":{"name":"Journal of Conservative Dentistry and Endodontics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140276684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
