“…This number can also be expressed as a ratio or a percentage. 33 After Pg infection, all planes presented some degree of bone loss. When assessing alveolar bone loss, the vertical bone height percentage was compared by subtracting the value found in the Pg-infected group from that found in the control group to assess how much loss occurred at each site.…”

Purpose This study introduces a standardized 2-plane approach using 8 landmarks to assess alveolar bone levels in mice using micro-computed tomography. Materials and Methods Bone level differences were described as distance from the cemento-enamel junction (CEJ) to alveolar bone crest (ABC) and as percentages of vertical bone height and vertical bone loss, comparing mice infected with Porphyromonas gingivalis (Pg) to controls. Eight measurements were obtained per tooth: 2 in the sagittal plane (mesial and distal) and 6 in the coronal plane (mesiobuccal, middle-buccal, distobuccal, mesiolingual, middle-lingual, and distolingual). Results Significant differences in the CEJ-to-ABC distance between Pg-infected mice and controls were found in the coronal plane (middle-lingual, mesiobuccal, and distolingual for the first molar; and mesiobuccal, middle-buccal, and distolingual for the second molar). In the sagittal plane, the distal measurement of the second molar was different. The middle-buccal, mesiobuccal, and distolingual sites of the first and second molars showed vertical bone loss relative to controls; the second molar middle-lingual site was also different. In the sagittal plane, the mesial sites of the first and second molars and the distal site of the second molar showed loss. Significantly different vertical bone height percentages were found for the mesial and distal sites of the second molar (sagittal plane) and the middle-lingual and distolingual sites of the first molar(coronal plane). Conclusion A reliable, standardized technique for linear periodontal assessments in mice is described. Alveolar bone loss occurred mostly on the lingual surface of the coronal plane, which is often omitted in studies.

Introduction: Periodontitis is one of the major reasons for tooth loss in adults. Therefore, it is important to know the true prevalence of the disease. Aim: This study was designed to find out the prevalence of periodontitis in Delhi state based on the American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) 2017 classification scheme. Materials and Methods: It was a descriptive cross-sectional study involving 2200 patients. Periodontal data were collected using the Community Periodontal Index of Treatment Needs-Epidemiological probe. Periodontal disease was diagnosed with the 2017 AAP and EFP definitions and classifications. Results: Of the study population, 93.2% had no detectable clinical attachment loss (CAL), 34.8% (n = 52) were classified with Stage I, 34.8% (n = 52) with Stage II, 16.8% (n = 25) with Stage III, and none with Stage IV periodontitis. Grade A was the predominant grade, being diagnosed in 50% of the periodontitis cases. The majority of cases (62%) demonstrated generalized periodontitis. Conclusion: The new periodontal disease classification system introduced in 2017 has provided a comprehensive description of periodontal disease which can classify the periodontal disease on the basis of various factors. Based on this, our study reported a maximum number of Stage I and II periodontitis patients.
