Introduction: Periodontitis manifested by the presence of periodontal pocket depth and loss of attachment level is detected and measured by using periodontal probes. Various generations of probes have been discovered and are used to measure the pocket depth. There has been a huge difference in the accuracy of different generations of probe. Aim: To compare the interprobe accuracy of first, second and third generations of probe on clinical parameters in patients with chronic periodontitis. Materials and Methods: This randomised comparative clinical study was conducted at the Department of Periodontics, Bapuji Dental College and Hospital, Davangere, Karnataka, India and included 30 chronic periodontitis patients, randomly allocated into three groups with each group consisting of 10 patients. The study was conducted over a period of eight months, from February 2001 to October 2001. Conventional periodontal probe, True Pressure Sensitive (TPS) probe and Florida probe were used to examine the patients. The probes were used in sequence of I, II and III for first 10 patients, II, III and I for next 10 patients and III, I and II for the last 10 patients to avoid bias due to examiner memory of clinical parameters. The recorded clinical parameters were Plaque Index (PI) (Silness and Loe 1964), Gingival Index (GI) (Loe and Silness 1963), Bleeding On Probing (BOP) index (Ainamo and Bay 1975), Probing Pocket Depth (PPD) and Clinical Attachment Level (CAL). At baseline, all the clinical parameters were recorded by two calibrated examiners i.e., Examiner-1 and Examiner-2. Examiner-I recorded all the clinical parameters postoperatively at Ist, IInd, IIIrd and IVth consecutive weeks. The statistical analysis was done using paired t-test, One-way Analysis of Variance (ANOVA), studentised range test and Karl Pearson’s correlation coefficient test for calculation and comparison of interexaminer and intraexaminer variability. Results: Among the 30 patients included in the present study, 22 were males and eight were females. The mean age of the patients involved in the study was 45.16±1.33 years. The mean value of PI and GI showed a statistically significant reduction at different intervals with a value of 0.16±0.21 and 0.22±0.21 postoperatively (4th week). The probing depths measured using Williams periodontal probe, TPS probe and Florida probe were reduced to 4.2±0.4 mm, 3.9±0.4 mm and 3.5±0.4 mm, respectively at the end of 4th week. The CAL measured using Williams periodontal probe, TPS probe and Florida probe were reduced to 7.0±0.6 mm, 6.6±0.5 mm and 6.1±0.6 mm, respectively at the end of 4th week. Conclusion: The TPS probe, Williams probe, and Florida probe showed their superiority regarding the accuracy of recording clinical parameters in the decreasing order respectively
Introduction: Periodontitis is a chronic inflammatory disease which affects the supporting tissues of the teeth and was initially thought to be environmental in origin. The difference in the disease prevalence among the population could not be attributed to environment alone. Limited studies have been done on diagnosing the future occurrence of periodontal diseases by recording the finger print patterns of the patients. Aim: To evaluate the relationship between finger prints patterns existing among patients with plaque induced gingivitis, chronic localised and generalised periodontitis. Materials and Methods: This was a cross-sectional observational study, carried out over a period of 6 months from January 2022 to July 2022) at Rajas Dental College and Hospital, Kavalkinaru. Subjects were equally divided into three groups including 100 patients under each group- Group-I as plaque induced gingivitis, group II as localised chronic periodontitis and group III as generalised chronic periodontitis based on 1999 classification system. The finger print patterns observed were loops, whorls and arches. The fingerprint patterns were compared within the group and also between the three groups. Boneferroni test and analysis of variance test were used for statistical analysis. Results: Total of 300 patients were included in this study, out of which 175 were males and 125 were females with the mean age 34.16±1.33 years. On comparison of the fingertip patterns within the groups, a significantly equal distribution of whorl and loop patterns with a value of 4.950±3.11 and 4.750±3.10 respectively were found among the Group-I subjects. A significantly increased prevalence of whorls with a value of 5.300±3.37 was found in Group-II subjects and significantly increased prevalence of loop pattern with a value of 5.800±2.72 was found among Group-III subjects. The arch pattern was more in Group-II and GroupIII when compared to Group-I with a value of 1.450±2.21 and 1.200±1.33, respectively. Conclusion: It was concluded that a strong association between fingerprint patterns and chronic periodontitis existed. The present study proved that dermatoglyphics can be used as a powerful tool for early prediction and better prevention of periodontitis.
