The relationship of initial clinical parameters to the long-term response in 112 cases of periodontal disease.
The purpose of the present study was to determine whether any of the clinical parameters recorded during an initial periodontal examination would relate to the course of periodontal cases maintained for long periods of time. Based on available documentation, cases which had a downhill course were assembled from a population previously studied. In addition, long-term cases currently under maintenance care were drawn from our private practice. On average, the patients had been under care for 23 years. The study population was heavily weighted toward downhill cases to better compare these cases with those usually found in periodontal practice. Positive statistical correlations were found between the amount of subgingival calculus and the degree of gingival inflammation at initial examination. Disease severity initially was positively correlated to long-term course of disease. The amount of subgingival calculus did not relate to the long-term result. There was a strong correlation between inflammatory gingival hyperplasia initially and good long-term maintenance. The results suggest that, in combination, initial characteristics of periodontal cases coupled with long-term results of treatment may aid in further subclassifying the periodontal diseases.
