The Impact of a Lacto-Ovo Vegetarian Diet on Post-Operative Recovery and Wound Healing Following Mandibular Third Molar Extraction—A Prospective Study

<b>Background/Objectives</b>: Despite the increasing popularity of lacto-ovo vegetarian (LOV) diets, their impact on oral wound healing remains underexplored. The aim of this study was to evaluate the potential influence of the LOV diet on soft tissue healing following lower wisdom tooth operation. <b>Methods</b>: This prospective study involved 40 participants equally divided into two groups: the LOV group (lacto-ovo vegetarians for at least seven years) and the control group (general diet). The main inclusion criterion was the need for third molar extraction, while smoking, pregnancy, and systemic diseases that may compromise wound healing were disqualifying factors. Parameters such as wound length, swelling, pain, analgesic use, and bacterial plaque index were assessed on the 3rd and 7th days post-surgery. <b>Results:</b> LOV participants exhibited significantly faster wound healing, with reduced wound length and swelling by the 7th day compared to the control group. Pain levels and analgesic consumption were also lower in the LOV group at the end of the observation period. Although the LOV group had higher trismus on the 3rd day, it normalized by the 7th day. These outcomes may be, apart of the diet type followed, partially attributed to the younger age and shorter surgical time observed in the LOV group. <b>Conclusions:</b> The findings highlight the potential role of dietary interventions in optimizing recovery, warranting further research to confirm these benefits in broader populations.
