Abstract
DesignRandomised controlled trial in a university setting.InterventionPatients were randomised to epinephrine impregnated gauze or aluminium chloride for periapical surgery involving a single tooth with a periapical area of <10mm.Outcome measureHaemorrhage control.ResultsOne hundred and twenty patients were randomised, with 98 being allocated. Forty-eight patients in the epinephrine group and 51 in the aluminium chloride group were analysed. Adequate haemostasis was achieved in 25 (52.1%) of the epinephrine group and 37 (72.5%) of the aluminium chloride group, a statistically significant difference.ConclusionsThe outcome showed better efficacy of haemostasis in the aluminium chloride group than in the gauze impregnated epinephrine group. The analysis of the patients and tooth-dependent variables showed no relationship with the effectiveness of haemostasis.
