Βακτηριακή αποίκηση σε ασθενείς με περιοδοντίτιδα ενηλίκων: μορφολογική μελέτη

THE PURPOSE OF THIS STUDY WAS TO IDENTIFY -BY USE OF DARK FIELD MICROSCOPY- MICROBIAL MORPHOTYPES IN DEEP POCKETS OF PATIENTS WITH ADULT PERIODONTITIS AND TO SEEK A PATTERN IN THEIR COLONIZATION SEQUENCE. THE CORRELATION BETWEEN THREE CLINICAL PARAMETERS (EDEMA, ERYTHEMA AND BLEEDING ON PROBING) AND THE PRESENCE OFMICROBIAL MORPHOTYPES WAS ALSO STUDIED. SIXTY ADULT PATIENTS (26 MALE AND 34 FEMALE) WERE USED, WITH MODERATE TO ADVANCED PERIODONTITIS AS DETERMINED BY CLINICAL AND RADIOGRAPHICAL CRITERIA. A SITE FOR MICROBIAL SAMPLING WAS SELECTED INEACH PATIENT WITH POCKET DEPTH EXCEEDING 6 MM AND RADIOGRAPHIC EVIDENCE OF BONE LOSS. MORPHOTYPE INDENTIFICATION WAS BASED UPON THE CRITERIA ESTABLISHED BY LISTGARTEN AND HELLDEN (1978) AS MODIFIED BY OFFENBACHER ET AL (1985). MICROBIALMORPHOTYPES WERE ENUMERATED UNDER OIL AT 1000 MAGNIFICATION ON AN OLYMPUS BH-2MICROSCOPE USING DARKFIELD OPTICS. EXAMINATION OF THE CLINICAL PARAMETERS REVEALED THAT 86,6% OF THE SITES WERE POSITIVE FOR EDEMA, 80% FOR ERYTHEMA AND 93,3% FOR BLEEDING ON PROBING. THERE WAS A STATISTICALLY SIGNIFICANT CORRELATION BETWEEN EDEMA AND ERYTHEMA (P<0.01). IN ADDITION, STATISTICALLY SIGNIFICANT RELATIONS WERE NOTED BETWEEN EDEMA AND ERYTHEMA AND THE PRESENCE OF SMALL, MOTILE COCOBACILLI. DATA ON THE PRESENCE OF BACTERIAL MORPHOTYPES -WHEN EXPRESSED IN PERCENTAGES- GAVE THE FOLLOWING RESULTS: S-SP:93,3%, L-SP:30%, S-MO-R:100%, L-MO- R:88,3%, S-MO-CB:75%, VO:51,6%, FUS:60%, FIL:83,3%, S-R:76,6%. A HIGHLY SIGNIFICANT CORRELATION (P<0.01) WAS FOUND BETWEEN SMALL AND MEDIUM SPIROCHETES. STATISTICALLY SIGNIFICANT CORRELATIONS (P<0.1) WERE ALSO REVEALED BETWEEN FUSIFORMS AND SHORT RODS AS WELL AS BETWEEN FILAMENTS AND SHORT RODS.
