Table 2. Periodontal indexes of patients with and without H. pylori infection.

Periodontal indexes	H. pylori positive	H. pylori negative	p value
Plaque index	2.231 ± 0.1216	2.067 ± 0.0667	p > 0.05
Bleeding index	2.462 ± 0.2683	2.333 ± 0.1869	p > 0.05
Probing depth (mm)	5.846 ± 0.4507*	4.667 ± 0.1869	p < 0.05
Attachment loss (mm)	7.231 ± 0.3782*	6.133 ± 0.2153	p < 0.05

Data were expressed as mean ± SD. Periodontal index of each site from selected patients were measured.

^*There was significant difference between patients with and without H. pylori in probing depth and attachment loss.
