Diverse microbiota in palatal radicular groove analyzed by Illumina sequencing: Four case reports

Figure 3 Alpha diversity analyses of bacterial communities in various sections of palatal grooves diagnosed with endodontic-periodontal infections. A: The Chao1 richness estimator; B: The angiotensin converting enzyme richness estimator; C: The Shannon diversity index; D: The Simpson diversity index. Boxes and dots represent the values generated from each group. Line in the middle of the column indicates the average value of each part. P values were shown above the connection lines, and no significant differences were detected among groups. ACE: Angiotensin converting enzyme; GG: Cervical samples; GJ: Apical samples; GZ: Middle samples.
