A Comparative evaluation of vasoconstrictor efficiency between adrenaline and triphala during gingival retraction in tooth preparation for fixed partial denture-An Observational study.

BACKGROUND: Gingival retraction is a critical step in tooth preparation, particularly for fixed partial dentures, as it allows for the proper exposure of the gingival margin. This facilitates precise impression-making and ensures that the final restoration fits accurately. Effective gingival retraction requires controlling gingival bleeding and ensuring that the retraction cord properly displaces the gingiva without damaging the surrounding tissues. Hemostasis is an essential aspect of this process, as uncontrolled bleeding can interfere with the impression-taking process and compromise the final prosthesis. Traditionally, vasoconstrictors like adrenaline have been used in combination with retraction cords to control gingival bleeding. Adrenaline works by constricting blood vessels, reducing blood flow and achieving rapid hemostasis. However, there are concerns regarding its systemic effects, especially in patients with cardiovascular issues or sensitivity to vasoconstrictors. This has led to the exploration of alternative agents, such as herbal astringents, that can offer hemostasis with potentially fewer side effects. Triphala, a well-known polyherbal formulation in Ayurvedic medicine, consists of three fruits: Amalaki (Emblica officinalis), Bibhitaki (Terminalia bellirica), and Haritaki (Terminalia chebula). It has been studied for its various therapeutic effects, including anti-inflammatory, antimicrobial, and astringent properties. Given its potential as a hemostatic agent, Triphala presents a promising alternative to chemical vasoconstrictors like adrenaline. AIM: The aim of this study is to compare and evaluate the effectiveness of an herbal astringent (Triphala) against a chemical vasoconstrictor (adrenaline) in achieving hemostasis during gingival retraction for tooth preparation. Through a randomized, double-blind approach, the study seeks to determine whether Triphala can serve as an effective and safe alternative to adrenaline in clinical practice, thereby expanding the options available for gingival retraction procedures in modern dentistry. MATERIALS AND METHOD: Adrenaline, Triphala and Retraction cords are the materials used.3 Groups with Group A as Triphala Churanam injected plain cords , Group B being Adrenaline injected plain cords and Group 3 as plain retraction cords(control). 5.5-30% of the salt form of triphala is mixed with polyol gel of about 67-90% and made into a solute. This is then injected into the OOO plain retraction cords and is dwelled until solidification occurs. The cords are then placed after tooth preparation during gingival retraction in 3 different groups. The efficiency of hemostasis is assessed in the groups by visualization with, score 0-no bleeding,score1-bleeding controlled with air and water spray within 1 minute, and score 2-bleeding not controlled within 1 minute. Comparison between these three groups are to be done by double blinding randomization method. RESULTS: The results were statistically analyzed using SPSS-Statistical Package for the Social Sciences windows software. The mean value of the bleeding index between the groups were calculated and standard deviation and f value were compared within the groups using one way ANOVA and post hoc test with 95%confidence level. CONCLUSION: The comparison between Group A and B were statistically insignificant, which implies that Triphala can be used as an adjunct to adrenaline in modern day practice in retraction cords.
