Determining the Frequency, Severity and Complications After Periodontal Surgeries

Periodontal surgeries complications and related factors are one of the most important things that surgeons in each clinic should be aware of to prevent them. Therefore, the aim of this study was to determine and compare the frequency, severity and trend of complications after periodontal flap surgeries with and without ostectomy and related factors in the periodontics department of Tehran University of Medical Sciences.

patients in the periodontics department of Tehran University of Medical Sciences, who underwent periodontal flap surgery or gingivectomy, were included in this prospective study. The pain, swelling, and bruising levels were asked on the same day, one and three days later. At the follow-up session on the seventh day, the pain, swelling and bruising levels were asked again, the tenderness and swelling levels were recorded by the surgeon, and flap dehiscence and pus presence were assessed. The difference between the complications’ levels on different days and also the difference in their trends between different surgeries was measured by GEE test, alongside testing the association of background and surgery characteristics with the complications’ levels by Mann-Whitney and correlation tests.

The pain and swelling means on days 0 and 1 respectively were significantly higher than other days. The trend of means for complications were not different between the two groups of flap surgery with and without ostectomy. Tenderness, swelling, flap dehiscence and pus were present in 31%, 31%, 1% and 0% of patients after one week, respectively.

Complications after periodontal flap surgeries were uncommon, except for mild pain and swelling.
