Study summary

The aim of the study is to evaluate the influence of PRF application in case of alveolar osteitis.

Read the detailed description

The main objective was to compare the effects of using two different methods in the treatment of dry socket (alveolar osteitis), which is a postoperative complication of dental extraction. The first was Nipas, applied, if dry socket was diagnosed following a tooth extraction. In case of subsequent extraction of homonymous tooth and reoccurrence of dry socket, patients were treated with application of PRF.

Exclusion criteria

Exclusion Criteria:

  • patients treated previously for existing dry socket,
  • patients allergic to acetylsalicylic acid ,

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

What researchers measure

Primary outcomes

  1. Intensity of pain vs. PRF and Nipas application

    In order to evaluate the relationship between intensity of pain after application of PRF and Nipas, Numeric Rating Scale pain scale is used. NRS is a horizontal line with an eleven point numeric range. It is labeled from zero to ten, with zero being an example of someone with no pain and ten being the worst pain possible. The higher score means worse outcome in case of present study.

    Time frame: 24 hours

  2. Influence of treatment on bacteria levels in wounds

    The second part of the study was dedicated to analyzing the number of bacteria in tooth extraction wounds.

    Time frame: 24 hours
