      Abstract

      In this study, we aimed to examine the effectiveness of self-irrigation following the extraction of mandibular third molars. A randomised controlled clinical trial was conducted with 155 patients who had undergone extraction of a mandibular third molar. The irrigation group was instructed to self-irrigate the extraction socket with tap water using a syringe three times a day, starting seven days after the tooth extraction. The incidence of complications and mouth opening, halitosis, plaque/gingival index, and oral health-related quality of life (OHRQoL) were measured. The irrigation group showed a lower incidence of complications than the non-irrigation group. The halitosis, plaque, and gingival scores were lower by mean (SD) 19.66 (5.19), 0.58 (0.06), and 0.62 (0.08), respectively, in the irrigation group than in the non-irrigation group (p = 0.0001). A greater amount of food packing was associated with higher halitosis, plaque, and gingival scores and poorer OHRQoL (p < 0.05). Further, more frequent irrigation was associated with lower halitosis, plaque, and gingival scores and better OHRQoL (p ≤ 0.016). Self-irrigation of the extraction socket using a syringe containing tap water is a very effective method for keeping the extraction socket clean. This technique reduced halitosis, improved plaque and gingival indices, and increased OHRQoL.
