What does symptomatic apical periodontitis refer to?

Inflammation usually of the apical periodontium, producing clinical symptoms including a painful response to biting and/or percussion or palpation. It might or might not be associated with an apical radiolucent area. Signup and view all the answers

Study Notes

Periodontal disease and endodontic disease are two distinct types of dental diseases that can impact the oral health.
Periodontal disease: causes inflammation in the extra-radicular tissues, leads to apical migration of attached gingiva and crestal bone loss, and usually has a vital pulp.
Endodontic disease: sources inflammation from the pulp, leads to apical bone loss, and usually has a non-vital pulp.
The dental pulp and periodontal tissues are intimately related during tooth development, with three main avenues for communication: dentinal tubules, apical foramen, and lateral and accessory canals.
Dentinal tubules: serve as communication pathways between the pulp and PDL, extend from the pulp to the dentino-cemental junction, and have a diameter ranging from 1 to 3 microns.
Apical Foramen: most direct route of communication to the periodontium and can cause periapical pathosis due to bacterial and inflammatory byproducts.
Lateral and Accessory Canals: present in about 30-40% of teeth, and can facilitate the spread of infectious material from the pulp to the PDL.
Periodontal disease has a negligible effect on the pulp until it involves the apex, and causes tissue destruction (resorption of bone, cementum, and dentin) leading to periapical radiolucency.
Effects of periodontal disease on the pulp are degenerative in nature, including an increase in calcifications, fibrosis, and collagen resorption.
Periodontal disease and endodontic disease can be challenging to diagnose and treat due to their interconnectivity.
Simon, Glick, and Frank developed a classification system for endo-perio lesions based on their origin and involvement.
Primary Endodontic Lesions: tooth is non-vital, signs and symptoms include sensitivity to percussion and palpation, sinus tract and apical and lateral bone resorption.
Primary Periodontal Lesions: tooth is vital, signs and symptoms include gingival swelling, loss of crestal bone, supporting periodontal soft tissues, and clinical attachment.
Primary Endodontic Lesions with Secondary Periodontic involvement: untreated suppurating primary endodontic disease leads to periodontal breakdown, and requires both endodontic and periodontal treatments.
Primary Periodontal Lesions with Secondary Endodontic involvement: apical progression of a periodontal pocket leads to involvement of the pulp, and rare cases may require extraction.
True Combined Lesions: endodontic and periodontal diseases exist concomitantly and can be challenging to diagnose and treat, and usually require extraction.
