Brief summary
Smoking and dual using associated with poor periodontal health.
Detailed description
Aim: To investigate how snuff use, smoking and risk behaviour affect periodontal health and mortality in a Swedish cohort, hypothesizing that they indeed have a poor impact and increase the risk of death. Material and methods: Study cohort of 1080 subjects aged 31 to 40 years (528 men and 552 women) from Stockholm area was clinically examined in 1985 and followed for mortality until 2015. Associations between periodontal health parameters, snuff use, smoking and age of death were analysed by classifying all subjects into four groups: dual-users (current snuffers and current smokers); pure snuffers (current non-smoking snuffers); pure smokers (current non-snuffing smokers) and non-users (non-snuffers, non-smokers). SPSS was used for analyses.
