The effects of orthognathic surgery on periodontal status

The aim of this study was to investigate the effects of orthognathic surgery on periodontium in the 3rd and 6th months after the operation. Methods: In a total of 10 orthognathic surgery patients (7 females, 3 males, mean age 23.2 ± 4.83), full mouth clinical periodontal measurements such as plaque index (PI), gingival index (GI), probing depth (PD), bleeding on probing (BOP), clinical attachment level (CAL), and mobility (M) were performed before the surgical procedure (T0) at all teeth except the third molars. Six of these patients underwent double jaw orthognathic surgery, 2 patients sagittal split ramus osteotomy, and 2 patients Le Fort I osteotomy. The same full mouth clinical periodontal measurements were repeated in the 3rd (T1) and 6th (T2) months after surgery. Results: There was no statistically significant difference between the T0 and T1 and T2 values in any of the parameters (PI, GI, PD, BOP, CAL, and M) at any of the regions measured (maxillary teeth, mandibular teeth, or full mouth). Conclusion: Within the limits of this study, it has been observed that orthognathic surgical treatments do not have a significant effect on periodontal status. However, further studies are needed before final conclusions can be provided
