Gingivitis is an inflammatory condition of the gingival tissue, most commonly caused by bacterial infection.The plaque control is considered the most important preventive factor concerning caries, gingivitis, and periodontitis Mechanical means of plaque control, e.g. tooth brushing, flossing and use of other mechanical devices are the most commonly used methods. However, ideal plaque control solely by mechanical means requires a significant effort and is difficult to achieve.This has led to the introduction of chemical methods of plaque control using antimicrobial agentsMore specifically, chemotherapeutic agents with antimicrobial properties, such as 0.12% chlorhexidine (CHX).chx has side effects encourage the need to develop alternative mouthwashes with similar efficacy but without these issues.hence the mouthwash enriched with a combination of aqueous extracts of Salvadora persica L. and green tea used as a substitution to CHX with minimal side effects .The objective of this study was to investigate the efficacy of the combination of Gt aqueous extract and Sp aqueous extract in reducing plaque buildup and gingivitis for 4 weeks duration.
