Trauma to a [[:Category:Teeth - Anatomy & Physiology|tooth]] (mechanical, chemical, thermal, infective) often results in [[Enamel Organ#Pulp|pulpal]] inflammation ('''pulpitis''').

Treatment for all three entities is the same, i.e. [[Endodontic Treatment|'''endodontic therapy''']] or if there are complicating factors, e.g. advanced [[Periodontitis|periodontitis]], then extraction.

* A Class I lesion, or endodontic–periodontic lesion, is endodontic in origin, i.e. pathology begins in the pulp and progresses to involve the periodontium.

* A Class II lesion, or periodontic–endodontic lesion, is periodontic in origin, i.e. pathology begins in the periodontium and progresses to involve the pulp. <font color="red">(picE10) </font color>

* A Class II lesion, or periodontic–endodontic lesion, is periodontic in origin, i.e. pathology begins in the periodontium and progresses to involve the pulp.  

* A Class III lesion, or true combined lesion, is a fusion of independent periodontic and endodontic lesions.
