Abstract
The purpose of this investigation was to clinically and histologically evaluate the pulps of severely periodontally involved teeth, after vigorous root scaling and planning had been performed. About 110 human teeth with severe amounts of periodontal disease were randomly selected for participation in this study. One-half of this sample was used as controls, so that each treated tooth had its own control from the same patient.
The specimens were carefully documented as to their previous periodontal status and their present status. Radiographic analysis, occlusal, and pulp vitality tests were thoroughly performed to assess the condition of the pulpal tissues. All pretreatment specimens must have tested clinically normal in order to be included in this study. The teeth selected to be treated were scaled and root planed at various depths depending on the extent of the periodontal disease. A two week recovery period was allowed. Prior to extraction, the same thorough diagnostic procedures were performed. The teeth were then carefully extracted, fixed, sectioned, and stained.
The histologic examination confirmed the clinical findings. Seven teeth out of 62 treated teeth became pulpless. Six of these had to be opened for drainage on an emergency basis. Ten teeth developed a pulpitic condition. Fourteen teeth developed clinical hyperemia. Histologic evaluation also revealed various stages of pulpal inflammation from the apex of the root, coronolly. It was therefore concluded that periodontal curettage may sever lateral or apical canals causing loss of blood supply and eventual total necrosis through a retrograde pulpitis.
