Abstract :This study investigated the clinical effects of low-intensity laser therapy (LLLT) on gingival tissue integrity and healing following tooth extraction in cats. Twenty-four cats of different breeds, genders and weights were randomly selected for the study. The cats were divided into two groups, with 12 cats in each group. The first group received antibiotics and painkillers after extraction, while the second group received antibiotics and underwent DYLT at 4 J/cm² on days 0, 4, and 10, scanning the entire damaged gingiva for 90 seconds. The cats were evaluated on postoperative days 0, 4 and 10 using gingival mucosa measurements and the methylene blue test. Preoperatively, on day 0, the mucosal condition was similar in both groups. On postoperative day 4, bright pink mucosa was observed in 41.7% of cats in the laser group. By contrast, all cats in the control group showed redness (either partial or severe) and oedema (8.3% of cats in the laser group versus 83.3% in the control group). By day 10, the mucosa was bright pink and swollen in all cats in the laser group. In the control group, light pink mucosa was observed in 41.7% of cats, with oedema observed in 58.3%. The healing rate of the gingival wound, measured using longitudinal and horizontal rulers, showed a significant difference between the groups on days 0-4 and 4-10 (p <0.001). A significantly higher healing rate was observed in the laser group compared to the control group. According to the methylene blue findings, gingival healing was observed in 75.6% of cats in the laser group and 44.2% of cats in the control group on day 4. While all cats in the laser group had recovered by day 10, healing was delayed in 29.1% of the control group. In conclusion, applying LLLT at an energy density of 4 J/cm² was found to be effective in accelerating wound healing and supporting the return to oral feeding after tooth extraction in cats, by reducing oedema and inflammation.
