Fig 2. Histomorphometric analysis of periodontal tissues.

Fig 2

Means and standard deviations of ANB (A; furcation area) and AL (B; interproximal area), with comparisons among groups. Photomicrographs of periodontal tissues in the furcation (C-F) and interproximal areas (G-J) of mandibular first molars: Group C (C and G); Group PROB (D and H); Group EP-SRP (E and I); Group EP-SRP-PROB (F and J). Abbreviations and symbols: ab = alveolar bone; ct = connective tissue; pdl = periodontal ligament; ANB = area of no bone; AL = attachment loss; FM = first molar; SM = second molar; black arrows = cementoenamel junction; white arrows = epithelial attachment; * = p<0.05; ** = p<0.01; *** = p<0.001. Scale bars: C-J = 200 μm. (Hematoxylin and Eosin stain).
