High risk
  • Active periodontal pocket with inflammatory exudation
  • Diffuse (active) periodontitis – Periodontal pockets 5 mm or more, BOP+
  • Periodontal abscess in a multirooted tooth
  • The risk in these cases increases the tooth mobility and grade of mobility
  • Fistula with inflammatory exudation
  • Denticio difficilis
  • Acute apical periodontitis
  • Chronic apical periodontitis with fistula
  • Chronic apical periodontitis not bordered
  • Peri-implantitis IMI = 4
Medium risk
  • Endodontic treatment of the root canal insufficient – bordered chronic periodontitis present – lamina corticalis intact – the focus larger than 2 mm
  • Semi-impacted teeth
  • Cysts
  • Peri-implant mukositis IMI = 2, 3
  • Caries close to the pulp or penetrating the pulp ++ with periapical clearance
  • Initial periodontitis
  • Furcation lesions uncleaned or uncleanable
  • Periodontal abscess in a single-rooted tooth
  • The risk in these cases increases the tooth mobility and grade of tooth mobility
  • Chronic plaque-related gingivitis with pseudo pockets
Low risk
  • Endodontic treatment of the root canal sufficient – bordered chronic periodontitis present – lamina corticalis intact, clearance up to 2 mm
  • Endodontic treatment of the root canal insufficient – without periapical enlargement and lamina corticalis intact
  • Impacted teeth
  • Caries close to the pulp or penetrating the pulp ++ without periapical clearance
  • Poor oral hygiene without clinical findings on periodontium
  • Gingivitis without pseudo pockets
Note:

+ Caries close to the pulp or penetrating to pulp (cannot be accurately distinguished in X-ray image) – toxins are already present in periapical section – must be considered in cases with profound immunosuppression.
Dentin caries, pulpitis and compromise prosthetic works do not represent an infectious focus but should be solved prior to challenging general treatment.
The severity of periodontitis increases with the number and depth of periodontal pockets and with their inflammatory activity.

+ According to radiological findings, it is more appropriate to define "quiet periapical lesions" as intact periapical lamina corticalis. Alternatively, whether or not the periapical aperture is enlarged.
++ Caries close to the pulp or penetrating to pulp (cannot be accurately distinguished in X-ray image) – toxins are already present in periapical section, sometimes with clearance.
Dentin caries, pulpitis and compromise prosthetic works do not represent an infectious focus but should be solved prior to challenging general treatment.
