Histological location of a standardized periodontal probe in man.
The purpose of this study was to locate the position of the periodontal probe tip using a pressure of 126 N/cm2 (force of 0.30N using a round periodontal probe tip with a diameter of 0.55 mm). The influence of gingival inflammation on this position was also studied. Subjects with three levels of periodontal health and disease were entered into the study and each contributed one experimental tooth. At each site a standardized probing system was used to place a probe into a clinical pocket. The probe tip was luted to the test tooth surface. The tooth with its gingival tissue and probe tip was extracted, fixed, and processed for histological measurements. Distances in mm were obtained from the cemento-enamel junction (CEJ) to the probe tip, to the base of the crevice/pocket, and to the most coronal connective tissue attachment. Analysis of the data indicated that clinical inflammation was not a factor in the placement of the probe tip at crevice/pocket's landmarks relative to the CEJ; however variability of probing may have caused the non-significance. The probing system placed the probe tip 0.66 mm apical to the base of the crevice/pocket and 0.06 mm coronal to the most coronal connective tissue attachment. These conclusions corroborated the results of the previous study in dogs which predicted probe placement of 0.44 mm apical to the base of the crevice using the standardized pressure of this probing system.[1]References
