The objective of this research endeavour was to assess the efficacy of low\u2010level laser therapy and concentrated growth factor (CGF) in facilitating nerve recovery and wound healing in such instances. A total of thirty\u2010one patients (mean age 27.52\u2009\u00b1\u20095.79\u2009years) who presented with IAN injury after extraction were randomly assigned to one of three groups: control group (which received oral mecobalamin), CGF group (which received CGF gel applied to the extraction sockets) and laser group (which received low\u2010level lasers (808\u2009nm, 30\u2009mW, 10\u2009J\/cm<jats:sup>2<\/jats:sup>)) at the extraction site. Patients' recovery from IAN paresthesia was evaluated seven times over the course of 14\u2009days utilizing visual analogue scale (VAS) and the pinprick test (PP). At multiple intervals following surgery, periodontal probing and bone level measurements were utilized to assess the recovery of both soft and hard tissues. The findings revealed that, compared with the control group, both the CGF and laser treatment groups exhibited a markedly greater improvement in VAS scores and wound healing of soft tissues, as well as in PP results (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), indicating enhanced wound healing processes. Despite these improvements, there was no significant difference in wound healing outcomes between the CGF and laser groups. Notably, the CGF group showed a statistically significant improvement in healing bone defects at 30 and 90\u2009days post\u2010treatment compared with the control group (<jats:italic>p<\/jats:italic>\u2009=\u20090.003 and <jats:italic>p<\/jats:italic>\u2009=\u20090.004, respectively), underscoring its effectiveness in bone healing as a critical aspect of the overall wound healing process. However, in terms of other wound healing comparisons, no significant differences were observed. CGF and laser therapy significantly enhanced the healing of wounds, including soft tissue and bone recovery, in addition to accelerating the recovery of IAN injuries following mandibular wisdom tooth extraction. Although both treatments were equally effective in nerve recovery, CGF notably excelled in promoting bone healing, suggesting its pivotal role in comprehensive wound healing. This highlights that both CGF and laser therapy are viable options for not only nerve recovery but also for overall wound healing in such dental procedures.<\/jats:p>","DOI":"10.1111\/iwj.14651","type":"journal-article","created":{"date-parts":[[2024,1,16]],"date-time":"2024-01-16T04:18:20Z","timestamp":1705378700000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["RETRACTED:
