Purpose/Objectives: To study the influence of periodontal disease on the dental pulp. Materials & Methods: The study consists of two parts: Part I: Survey Study – 106 periodontally involved teeth were selected from patients 19-70 years of age. The teeth were divided into four groups according to the severity of periodontal disease, based on how much of the root was exposed on radiographic examination. The teeth were sectioned and looked at histologically. Part II: Paired Control Series – Twenty-two teeth from four patients, ages 39-50 years, were collected. Seven of the teeth had normal periodontium and served as controls. The remaining 15 teeth were divided into four groups according to severity of periodontal disease, as was done in Part I. All teeth were sectioned and examined microscopically. Results: Control teeth showed pulpal changes similar to periodontally involved teeth. In Part I, no relationship was observed between the amount of exposed root and the changes in the pulp. In each of the four periodontal disease groups there was a full array of pulpal changes, from mild to most severe, including complete pulpal degeneration and/or calcification. In Part II, it was found that the teeth from the same patient having a wide variety of periodontal involvements had pulps that were histologically the same or similar. Between patients, the pulpal condition varied from almost normal to advanced degeneration. There was no correlation to age and pulpal status. Author’s Conclusion: The authors conclude that the investigation disproves any influence of periodontal disease on the pulpal tissue of the involved teeth and that the pulpal structures of teeth from the same patient are similar, regardless of the degree of severity of periodontal involvement Validity of Conclusion: Conclusions are of questionable validity. Reviewer’s Comments: I think this was a good study, but the criteria for severity of periodontal disease was based solely on radiographic information/bone loss and not in conjunction with clinical findings such as probing depths and overall health status of soft tissues. This may or may not make a difference on the findings of the study, but this information would be valuable in trying to make these types of conclusions.
