Formulation and Development of Clove and Coriander Combination Herbal Dental Anticaries Gel and Evaluation of its Antimicrobial Activity

Background:: Dental caries is one of the Periodontal diseases that has been recognized as a major public health problem for decades throughout the world. It occurs in all groups, ethnicities, races, and genders at all socioeconomic levels. Natural remedies are more acceptable in the belief that they are safer with fewer side effects than synthetic ones. Clove and coriander oil are established herbal drugs for periodontal diseases. Objective:: This research work was intended to formulate a dental gel containing clove and Coriander as the major constituents and evaluate it for dental caries treatment. Both of the herbal oils have a vast range of antimicrobial activity against a great number of periodontal pathogens; therefore, they are used for periodontitis treatment. Methods:: The combination gel was prepared using carbopol 934 as a gelling agent, clove oil and coriander oil as therapeutic constituents, polyethylene glycol as a co-solvent, methyl paraben and propyl paraben as a preservative and a required quantity of distilled water as vehicle. Results:: The gel was analyzed for various properties like antimicrobial activity, pH, spreadability, extrudability, drug content etc., and it was shown that the combination gel is a satisfactory dosage form that is used in periodontitis treatment. The combination gel revealed the ZI (zone of inhibition) of about 22.05±0.04 mm. Conclusion:: The present study concluded that the combination gel preparations of clove oil and coriander oil reported satisfactory physicochemical properties along with good drug content compared to the single gel preparation.
