Smokers have a higher risk of inflammatory peri-implant disease than non-smokers

Oral Dis. 2018 Mar;24(1-2):30-32. doi: 10.1111/odi.12730.


Aim: To comparatively evaluate peri-implant health status in smokers and non-smokers.

Materials and methods: A total of 142 implants (74 implants in non-smokers, 68 in smokers) in 43 smoker or non-smoker systemically healthy patients were included in the study. Demographic and clinical periodontal data were recorded and analysed by chi-square and Mann-Whitney U tests.

Results: Peri-implantitis and mucositis cases were significantly more frequent in the smokers than non-smokers (p = .001). Suppuration, bleeding and plaque scores around the implants were significantly higher in smokers than non-smokers (p = .001; p = .002; p < .0001, respectively).

Conclusion: The present findings indicate that smokers have a higher risk of inflammatory peri-implant diseases. Therefore, more frequent recalls may be recommended in smokers with dental implants.
