Objectives:Periodontitis diagnosis and efficacy, ask the same period agent with good results between diagnosis and probe type on the correlation between the results with a certain degree of influence. By researching the ordinary periodontal probe (Hu-Friedy probe) and Florida periodontal probe respectively in periodontal basis for clinical treatment before and after repeated measurements to compare the results of correlation coefficient, thereby appraised the two probe their repeated measurements periodontal probing depth, PD and its clinical characteristics, and accumulated certain clinical information, probing depth periodontal agent for common periodontal treatment short-term curative effect evaluation based provide clinical experience and research.Methods:Choose the 30 cases in our hospital in 2010, moderate and severe chronic periodontitis patients, based in periodontal before and after treatment, separately using Florida periodontal probe and ordinary periodontal probe repeated measurements PD value twice each.820 teeth were measured four times PD value, periodontal foundation treatment, before and after the two times, each time 4920 a dot can obtain values,4 times has won 19680 a locus values. A comparative treatment before and after two kinds probe twice periodontal agent respectively domain-specific depth measuring values, calculating correlation coefficient.Results:Periodontal before and after treatment, ordinary periodontal probe and Florida periodontal probe successively twice each measured quantity PD value were good correlation, and(the correlation coefficient scope for 0.81 to 0.88), two probe all can reliably applied to periodontal disease clinical research. Based on in patients with chronic periodontitis, severe periodontal before and after treatment, based on comparative use Florida periodontal probe measurement PD variation value twice, P=0.02, P<0.05significant differences, compared to before and after treatment in patients with periodontitis, use normal periodontal probe measurement PD variation value twice, P=0.36, P>0.05non-significance difference.Conclusions:This study compares the ordinary periodontal probe and Florida periodontal probe their repeated measurements of correlation and the work characteristics, and achieved periodontal basis within three months after treatment, systematic and integrated clinical information. Based on research from the result:Two probe the correlation of their respective clinical measurements were well, can reliably used to evaluate the therapeutic effect of periodontal basis. In periodontal foundation treatment, due to Florida periodontal probe measurements accurate diagnosis to 0.2mm. Therefore, periodontal foundation treatment after short-term effect evaluation, Florida periodontal probes more dominant.
