Evaluation of the effects of AB0 blood types on the severity of peri-implant diseases

INTRODUCTION: Peri-implant diseases are inflammatory conditions with a complex etiology including host-related risk factors and genetic traits which may affect the soft and hard gum tissues around dental implants. The aim of this study was to evaluate the effects of blood types on the severity of peri-implant diseases.
METHODS: A total of 77 dental implants of 39 patients with peri-implant diseases were included. Demographic data of the patients such as age, sex, frequency of tooth brushing and interdental cleaning and blood types were recorded. Clinical variables such as probing depth (PD), gingival index (GI), and plaque index (PI) and radiographic bone loss level were also noted.
RESULTS: Dental implants were divided into two groups as Group 1 (n=19) including those diagnosed with peri-implant mucositis and Group 2 (n=20) including those diagnosed with peri-implantitis. The PD and GI scores and radiographic bone loss level were significantly higher in Group 2 than Group 1 (p<0.005). The frequency of tooth brushing was significantly higher in Group 1 than Group 2 (p=0.002). There was no significant difference in the distribution AB0 blood types between the groups (p>0.05). However, the majority of the patients had A Rh (Rhesus factor) (+) blood type in Group 1 and 0 Rh (+) blood type in Group 2.
DISCUSSION AND CONCLUSION: In conclusion, the blood types have no significant effect on the severity of peri-implant diseases.
