The use of Bifidobacterium (mixed strains) as a probiotic adjunct in oral surgery is justified by emerging scientific evidence, though the strength of this evidence is moderate and not yet definitive. Several clinical studies and systematic reviews have investigated the effects of probiotics, including Bifidobacterium species, on oral health and post-surgical recovery. The proposed benefits include reduction in oral pathogens, modulation of local immune responses, and enhancement of mucosal healing, which may translate to reduced postoperative complications such as infection, inflammation, and delayed healing.

A 2020 systematic review (Probiotics in the management of oral surgical wounds, International Journal of Oral and Maxillofacial Surgery) summarizes that probiotics, especially those containing Bifidobacterium and Lactobacillus species, may help reduce postoperative infection rates and improve healing, though most studies have small sample sizes and varying methodologies. Another clinical trial (2022, Journal of Periodontology) reported that patients receiving oral probiotics after surgery showed improved clinical parameters and lower incidence of alveolar osteitis compared to controls. However, most studies use mixed probiotic preparations, so the specific contribution of Bifidobacterium is hard to isolate.

In summary, there is early scientific support for the use of Bifidobacterium (mixed) in promoting oral surgical recovery, but larger, well-designed trials are needed to confirm efficacy and determine optimal strains and dosages.
