Abstract
Background
Post extraction bleeding requires effective management to promote healing and comfort. Black tea contains tannins with astringent and hemostatic properties that may aid in bleeding cessation. Material and methods: This parallel group randomized controlled trial included 44 patients undergoing forceps molar extraction, allocation (1:1) by simple randomization to either 0.5% povidone iodine impregnated gauze (PVI group, n=22) or black tea extract impregnated gauze (BTEI group, n=22). The primary outcome was primary bleeding cessation time (PBCT), assessed at 2-, 5-, and 7-minutes post-extraction. Secondary outcome was the occurrence of adverse effects.
Results
In the BTEI group, 54.5% achieved bleeding cessation within 2 minutes, with all achieving cessation by 5 minutes. In the PVI group, 77.3% stopped bleeding within 2 minutes, and all by 7 minutes. Data was analyzed using Chi-square test. The difference in PBCT between groups was not statistically significant (P = 0.104). No adverse effects were reported in either group.
