“…As regards the latter, it is our opinion that it is extremely hazardous to attempt to ascribe etiology to lesions based on their size. As regards the reliability issue, we have demonstrated that periodontal attachment loss may be diagnosed with a degree of reliability sufficient to warrant the considerations also of the more subtle levels of periodontal destruction (27).…”

“…The intraexaminer agreement for clinical attachment loss recordings ranged between 96.5% and 98.8%, while the corresponding interexaminer agreement ranged between 94.6% and 96.0% (27). No attempts were made to assess the reliability of the NUG recordings.…”

“…who conducted the clinical examinations in the case–control study was also the gold standard for the training and calibration of the examiners who conducted the screening examinations. Calibration was achieved using test–retest exercises in groups of patients before the screening examination study and repeated test–retest exercises in large groups of adolescents at different intervals during the screening examination (45). The overall percentage agreement for intra‐examiner reliability when assessing CAL ≥ 3 mm in the screening examinations was 99% and the corresponding overall kappa value was 0.85 (45).…”

It has become increasingly recognized that groups of microorganisms interact within the subgingival plaque of adult subjects with periodontitis. It is much less clear, however, whether the consortia of microorganisms associated with periodontitis are different in early and more advanced cases of periodontitis. To investigate this point further, subgingival plaque was collected from six sites in 87 adolescents with periodontitis and 73 controls and the samples were analyzed for the detection of 18 microbial species using the DNA-DNA hybridization technique. Actinomyces oris accounted for the highest proportion of the flora and was more predominant among controls. Prevotella nigrescens, Prevotella intermedia, Porphyromonas gingivalis, and Tannerella forsythia were present at higher levels among the subjects with periodontitis. Factor analyses identified one factor characterized by highly positive loadings for T. forsythia, Campylobacter rectus, P. gingivalis, P. intermedia, P. nigrescens, Parvimonas micra, and Treponema denticola, and another factor characterized by highly positive loadings of A. oris, Capnocytophaga ochracea, Eikenella corrodens, Streptococcus intermedius, Selenomonas noxia, Streptococcus oralis, Streptococcus sanguinis, and Veillonella parvula. Aggregatibacter actinomycetemcomitans and Streptococcus mutans did not load on any of the two factors, while Fusobacterium nucleatum loaded on both. These findings confirm the occurrence of clustering of subgingival bacteria according to case status also among young individuals.

“…Details on the sampling strategy, sample size estimations, participation rates, clinical recordings used to identify the cases, intra-and interexaminer reliability in the recording of CAL, and a detailed description of the clinical periodontal features of cases and controls have been previously published [8,9,11,12]. Ethical approval for the study was obtained from the Ethics Committee of the University of Chile, and informed written consent was provided by each participant or their parents, as appropriate.…”

The aim of this study was to assess whether adolescent cases of periodontitis present with different hemogram findings than control subjects. This case-control study comprised 87 adolescent cases presenting with clinical attachment loss ≥3 mm in at least two teeth and 73 control subjects. Blood samples were obtained by venipuncture and analyzed in an Abbott Cell-Dyn 3,500 hematology analyzer for values of white blood cells and red blood cells, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, red-cell distribution width, platelets, and mean platelet volume. Hematocrit values were obtained using volume fractions read from capillary tubes. The associations between log-transformed hemogram variables with each of the three exposure variables "case status" (yes/no), a "high percent sites with PD ≥4 mm" (yes/no), and a "high percent sites with BOP" (yes/no) were investigated using multivariate linear regression analyses. Periodontitis cases presented with 5% higher values for the mean platelet volume than did controls. Subjects with a high percent sites with probing depth ≥4 mm had eosinophil counts that were on average 27% lower than among subjects with fewer deepened pockets. They also had 7% higher values for the mean platelet volume than did persons with less pocketing. Eosinophil counts and mean platelet volumes may be associated with the parameters of periodontitis in adolescents. While standard hematological testing did not show abnormalities in adolescents with periodontitis compared to healthy controls, eosinophil counts and mean platelet volumes may reflect periodontal inflammation.

Reliability of Clinical Attachment Level Recordings: Effects on Prevalence, Extent, and Severity Estimates

Abstract: Examiner variation may preclude comparisons of prevalence estimates between studies. Valid comparisons may be made between studies of extent estimates provided that uniform parameters are used to express the extent of periodontal breakdown.
