This study assessed the porcine palatal mucosa dissolution, from artificial grooves, by a final rinse of sodium hypochlorite (NaOCl) solely or mixed with Keratobacter ((KB); or agitation) passive ultrasonic irrigation (PUI) or sonic activation (SA). Soft‐tissue samples ( n = 123) were weighed and placed inside root canal grooves in central maxillary incisors. The specimens were randomly divided into six test groups ( n = 20): NaOCl 3% with or without KB and the irrigation dynamics: positive pressure (PP), SA or PUI. An EDTA intermediate rinse was included. Soft‐tissue weights were measured subsequently. The NaOCl + KB_PUI group showed the highest mean weight reduction, whilst the NaOCl_PP group recorded the lowest. NaOCl + KB subgroups were associated with hastened reduction compared with NaOCl subgroups. NaOCl_PP presented with significantly lower weight reduction when compared with the remaining experimental groups. The addition of KB to NaOCl or its agitation enhances tissue dissolution ex vivo . The agitation of KB‐containing mixtures offers no further benefits.
